Listening to what Xiaolongnu said, Tang Xiaosheng was quite surprised.

Since the year 2069, humans have been investigating the origins of the scientific research base beneath Crescent Island. It is inconceivable that such a large and advanced scientific research base can be quietly established on such an island.

Exactly how the basement of Crescent Island was built remains a mystery to this day.

Tang Xiaosheng had a variety of speculations about this mystery, among them, he suspected that this scientific research basement might have traveled through time and did not originally belong to the earth.

This suspicion was originally a fictitious speculation and was not credible.

It wasn't until today, when Xiaolongnu said that the basement of Crescent Island was a bit like an ancient tomb at the foot of Zhongnan Mountain, Tang Xiaosheng felt that his previous guess was not completely impossible.

"Long'er, do you really think that this basement is a transformation of an ancient tomb?" Tang Xiaosheng verified that although he had been to the time and space of "The Legend of the Condor Heroes", because the soul of "Yang Guo" in his body had been refined into a soul pill, and the relevant memories had also been sealed, he did not have much impression of the ancient tomb.

"I'm not sure if it's from an ancient tomb, but as soon as I walk into this basement, I feel like I'm back in the tomb." "Although this basement is empty, without many of the tomb's chambers and mechanisms, its overall structure, wall decoration, soil texture, and height of the chamber are very similar to those of the tomb. ”

Hearing this, Tang Xiaosheng began to face up to Xiaolongnu's opinion. Soon after her birth, Xiaolongnu lived in the ancient tomb and lived there for more than 20 years. She was all too familiar with the environment of the ancient tomb, and it was unlikely that she would be mistaken.

Since the little dragon girl thinks that this basement is very similar to the ancient tomb, I am afraid that it is true.

In this way, Tang Xiaosheng couldn't help but suspect even more that this basement was related to the traverser. It may have been built by a time-traveler who had been to the tomb, or it could have traveled directly from time and space in The Legend of the Condor Heroes.

In order to further determine the reality of this basement, Xiaolongnu specially walked around, and as a result, the more she walked, the more she felt that the basement was the ancient tomb where she had lived for more than 20 years.

When Xiaolongnu, Xiaohuangrong, Guo Xiang and more than a dozen other people took a big turn in the basement, it was already more than 3 o'clock in the morning Beijing time, and it was only more than three hours away from 7 o'clock in the morning.

"Dad. It's almost 4 a.m. "At this time. Tang Xiaoyu reminded.

In just over three hours, Bai Jingjing in 2017 will travel to a female tourist on Thousand Star Island, and she will be able to get the moonlight treasure box at that time.

Anyway, this basement is empty, and there isn't much to visit. Tang Xiaosheng then suggested: "It's not too early. Why don't we go to Thousand Star Island now. Prepare a little ahead of time? ”

Everyone agreed.

After the discussion, Tang Xiaosheng, Xiaolongnu, Xiao Huangrong, Zixia and other fifteen people prepared to leave the basement, and then took the "Golden Pigeon No. 1" to Qianxing Island......

As the aircraft "Golden Pigeon 1" stopped on the beach on the east coast of Crescent Island. They need to get out of the basement and back to Crescent Island Beach before they can get on the plane.

So, everyone walked towards the exit of the basement, ready to return to the island.

Thinking of seeing the Moonlight Treasure Box soon, Tang Xiaoyu and Xiao Huang Rong were a little excited, and when they left the basement, the sisters trotted all the way, rushed to the front, and ran towards the exit of the basement together.

Unexpectedly, when they ran to the exit, an accident happened.

At the exit of the basement, there seems to be an invisible wall blocking the way. When Tang Xiaoyu and Xiao Huang Rong ran to the exit, the two petite bodies collided with this invisible wall, and with a bang, the two little Loli were suddenly bounced away by the invisible wall and flew out more than ten meters away!

"Rong'er! Rain! ”

Seeing this, Tang Xiaosheng and Dongfang Undefeated looked slightly shocked, their bodies flashed, and at the same time, they quickly stepped forward and hugged Tang Xiaoyu and Xiao Huang Rong who were bounced off the invisible wall.

"Rong'er, you're fine, right?" After hugging Xiao Huang Rong, Tang Xiaosheng immediately asked.

Xiao Huang Rong had the Northern Darkness True Qi Protector on her body, and the impact just now did not cause any harm to her, and she shook her head: "It's okay." Little finger pointed to the exit of the basement and asked curiously, "Brother Jing, I seem to have bumped into something there just now." ”

"I bumped into it too." At this time, Tang Xiaoyu, who was held in Dongfang Undefeated's arms, also asked Tang Xiaosheng in a childish voice, "Dad, what is that?" It's amazing, my sister and I were bounced off all of a sudden! ”

When Xiao Huang Rong and Tang Xiaoyu just ran to the exit of the basement, it was clear that they had bounced back after hitting a foreign object that had hit an invisible wall. It's just that Tang Xiaosheng doesn't know what this invisible wall is.

He had been to the basement of Crescent Island seven or eight times, and he had always come and gone without hindrance, and he had never found anything unusual.

Now, there was a foreign object blocking the exit of the basement, Tang Xiaosheng couldn't help but be suspicious, seeing that Xiao Huang Rong and Tang Xiaoyu were fine, he walked quickly towards the exit.

When he came to the exit, he suddenly stopped.

It wasn't because he didn't want to keep walking, but because something was holding him back, and he couldn't move half a step forward. As he walked through the exit, he felt a completely transparent wall blocking his path.

"There really is an invisible wall at the exit!"

After discovering this invisible wall, the internal force in Tang Xiaosheng's body turned, and his right palm was raised, shooting forward!

Boom!!!

When his right palm hit the invisible wall at the exit, there was a loud bang, and under the action of the rebound force, Tang Xiaosheng snorted, and was immediately bounced dozens of meters away.

Seeing this scene, Xiaolongnu, Zixia, Bai Xiaoxiao and others showed surprise on their faces at the same time.

After being bounced off, Tang Xiaosheng landed steadily, his body floated, and returned to Xiaolongnu, Zixia and others.

"Supreme Treasure, what's going on? How can there be something blocking the exit? Zixia asked strangely, she had been to this basement once before, and she didn't notice anything unusual at the exit, so she asked puzzledly. What is the transparent thing blocking the exit? ”

Tang Xiaosheng shook his head: "I don't know what to do, but it seems to be an energy wall." ”

"Energy wall?"

"Yes. I've just tried to break it with Northern Darkness True Qi, but it doesn't seem to work. Tang Xiaosheng said, "I'll try it again now with the power of my soul to see if I can break it." ”

After speaking, he condensed slightly, and several wisps of soul power gathered in his palm, and his heart moved. A burst of white light shot out. Hit the invisible wall directly at the exit!

Airplanes!!!

The soul power shot into the invisible wall, making a slight noise.

The invisible wall was even tougher than expected, and after being hit by the power of the soul, it seemed to be intact.

Tang Xiaosheng gathered ideas. Doubles the power of the soul. The white light that shot out suddenly flourished.

It's just that. The invisible walls are still not pierced.

Seeing this, Zixia, Bai Xiaoxiao, Qingxia, and Bai Jingjing on the side shot at the same time, and four white lights were sacrificed at the same time. Shoot at invisible walls.

Immediately afterwards, Xiaolongnu, Zhao Min, Ren Yingying, Wang Yuyan, Dongfang Undefeated, Xiao Zhao, Guo Xiang, Gan Nineteen Sisters and other eight people came out to support one after another.

Seeing that everyone had made a move, Xiao Huang Rong and Tang Xiaoyu were not idle, silently reciting the immortal formula, with a movement of their minds, with a wave of their little hands, two white lights containing the power of the soul shot towards the invisible wall.

In this way, Tang Xiaosheng, Xiao Longnu, Zixia, Xiao Huang Rong and other fifteen people cast spells at the same time, gathering the power of fifteen people, trying to use the power of their souls to break through the invisible wall at the exit.

After a while, the fifteen people had consumed a lot of soul power.

However, the invisible wall was still unharmed, and the soul power did not seem to cause any damage to it.

"Let's stop it, don't waste any more soul power." At this time, Tang Xiaosheng withdrew the spell and said to everyone, "Our soul power doesn't seem to have any effect on this invisible energy wall. ”

Hearing this, everyone withdrew their hands one after another, and Zixia asked, "What is this invisible wall, which has such a strong defensive ability?" ”

"This wall is a bit weird, but let's think about it in the long run! It's four o'clock in the morning, so we've got to get out of here. Tang Xiaosheng pointed to the stone wall above the basement and said, "Since the entrance is blocked by an invisible wall, we can't get out at all, so we can only use the "Wall Piercing Technique" to penetrate the stone wall and return to the top of Crescent Island." ”

Zixia nodded: "That's all I can do now." ”

"Dad, I'll come first!" At this time, Tang Xiaoyu said.

Tang Xiaosheng asked, "Yu'er, have you also learned the "Piercing Through the Wall"? ”

"Well, I learned it last year." Tang Xiaoyu said.

"I learned it the year before last!" At this time, Xiao Huang Rong interjected.

Tang Xiaosheng smiled and said, "Okay, then Yu'er and Rong'er will show their hands first." ”

So, Tang Xiaoyu and Xiao Huang Rong took a step forward, and the two little Loli calmed down slightly, silently reciting the immortal recipe of "Piercing the Wall" in their hearts, and the power of the soul in their bodies flowed rapidly.

Sou!

A moment later, the two little Lori's bodies flashed, turned into two white lights, flew off the ground like lightning, jumped up rapidly, and swept directly towards the wall above the basement!

Boom!!!

Tang Xiaosheng thought that Tang Xiaoyu and Xiao Huang Rong would be able to pass through the stone wall smoothly, but unexpectedly, when they hit the stone wall, they were directly bounced away and fell from mid-air.

Seeing this scene, Tang Xiaosheng and Dongfang Undefeated stepped forward again and caught the falling Xiao Huang Rong and Tang Xiaoyu respectively.

"Yu'er, you're fine, right?" After hugging Tang Xiaoyu, Dongfang Undefeated asked with concern.

Tang Xiaoyu shook his head, tilted his head, and looked at the stone wall above the basement, Xiao Liu bent his eyebrows, and asked strangely, "Why was I bounced back again?" Can't I wear "Through the Wall" too? ”

Hearing what she said, Tang Xiaosheng, Dongfang Undefeated, Zixia and others couldn't help but be slightly shocked in their hearts, and they all immediately realized something.

Sou!

At this time, Zixia moved, and also performed the "Wall Piercing Technique", turning into a purple light and flying upwards!

Boom!!!

There was another loud bang, and then, Zixia was unable to penetrate the stone wall, and was also ruthlessly bounced back.

After failing to penetrate the wall, Zixia did not give up, changed positions again, and tried seven or eight times in a row. Unfortunately, all attempts ended in failure.

On the stone wall above the basement, there seems to be an invisible wall shrouded in it!

"Could it be that the entire basement has been shrouded in an invisible wall of energy?" When the ninth failed to penetrate the wall, Zixia said worriedly.

Hear the words. Only then did everyone realize the seriousness of the problem.

In order to find out, Bai Xiaoxiao, Qingxia, Xiaolongnu, Ren Yingying, Bai Jingjing, Dongfang Undefeated and others have performed the "Crossing Technique" and tried in dozens of different directions in the basement. All attempts were equal, and they were bounced back by the invisible walls that shrouded them.

It was only then that the crowd was sure of one thing - they were trapped in this basement.

The entire basement has been enclosed by invisible walls.

As for what this invisible wall is, no one knows.

They have tried to penetrate this invisible wall with various methods such as soul power, "Wall Piercing Technique", and "Perspective Technique", but unfortunately, all efforts have been in vain.

"Wasn't this basement so good before, how could it suddenly be trapped?" Zixia asked suspiciously.

Tang Xiaosheng looked around and said, "Do you think that this basement has actually been set up by someone?" ”

"Lay out the formation?"

"Yes." Tang Xiaosheng analyzed. "This basement has now been turned into an absolutely enclosed space. We can't escape here even if we try our best, and this situation is exactly the same as the 'Great Five Elements Bagua Array'. ”

"You mean that the basement has been planted with the 'Great Five Elements Bagua Array'?" Zixia asked.

"Yes."

"However, the 'Great Five Elements Bagua Array' was invented by you, how can others use it? Let alone. The 'Great Five Elements Bagua Array' requires the cooperation of thirteen people to be activated. The formation is extremely complex. The average person is certainly not up to the task. Zixia said puzzled.

Guo Xiang on the side said: "If someone really laid the 'Great Five Elements Bagua Array' in this basement, it should have been laid down after we entered the basement. Thinking about it this way, there is a very important question - how did the people who set up the formation know that we would come to this basement today? ”

"And. If someone really set up the 'Great Five Elements Bagua Array' nearby, with the cultivation of more than a dozen of us, it would be impossible for them to be unaware. Bai Jingjing added.

Zhao Min's eyebrows moved slightly, and he said: "Your analysis is reasonable, according to common sense, it is true that no one can set up a 'Great Five Elements Bagua Array' to trap us here." However, it is precisely because of this that it seems even more terrifying. ”

Hearing what she said, everyone couldn't help but look at each other.

"Let's not scare ourselves, it's imperative to find a way to get out of here first." At this time, Tang Xiaosheng said.

Zhao Min said: "If the basement is really laid with the 'Great Five Elements Bagua', then how do we leave?" The 'Great Five Elements Bagua Array' blocked time and space at the same time, and it was a desperate situation at all, and even the ever-changing 'strange energy' could not escape. ”

Tang Xiaosheng also understood this truth, but he couldn't sit still, and said, "No matter what, we have to try it." This basement is so big, let's look separately, maybe we can find an exit. ”

At this point, there was no better way, so everyone had to try.

So, Tang Xiaosheng, Xiaolongnu, Zhao Min, Ren Yingying and other fifteen people acted separately and began to search all corners of the basement, hoping to find areas or exits that were not shrouded by invisible walls.

This basement is about the size of Crescent Island, which is about 3.4 square kilometers in size, which is larger than 200 football fields combined. To find an exit on such a large scale, the amount of work can be imagined.

After searching for nearly 1 hour, they still found nothing.

By the time we got here, it was already five o'clock in the morning, and there were only two hours left until seven o'clock. Two hours later, Bai Jingjing in 2017 will travel to Thousand Star Island, and if she doesn't rush to Thousand Star Island, she may miss the opportunity to get the Moonlight Treasure Box.

It was precisely because of the urgency of time that everyone couldn't help but speed up the search.

Tang Xiaosheng was looking for an exit on the ground east of the basement, at this time, he swept away and found that the little dragon girl was standing dozens of meters away and looking around, as if she was looking for something, and while looking for it, she kept measuring the distance with her footsteps, which looked a little abnormal.

So, Tang Xiaosheng stepped forward and asked, "Long'er, what's wrong?" Did you find something? ”

The little dragon girl's thin lips opened lightly and asked, "Later, do you remember when we were trapped in the ancient tomb?" ”

"Trapped in the Tomb?"

"Hmm." Xiaolongnu recalled, "At that time, my senior sister came to the ancient tomb to snatch the 'Jade Girl-Heart Sutra', so I put down the 'Broken Dragon Stone' in the ancient tomb. The exit was sealed, and as a result, me, Guo'er, my senior sister and others were all trapped in the ancient tomb. ”

Hearing what she said, Tang Xiaosheng remembered.

In the world of "The Condor Heroes", Li Mochou's master and apprentice once went to the ancient tomb to try to win the "Jade Girl-Heart Sutra", but the little dragon girl was no match for Li Mochou, so she put down the 'Broken Dragon Stone' of the ancient tomb and wanted Yang Guo to escape, while she herself continued to stay in the ancient tomb.

At that time, Yang Guo was reluctant to give up the little dragon girl. So he didn't leave alone. Outcome. Yang Guo, Xiaolongnu and Li Mochou's master and apprentice were all trapped in the ancient tomb.

Because the "Broken Dragon Stone" weighs thousands of pounds, once it is put down, it cannot be opened. Therefore, Yang Guo, Xiaolongnu, Li Mochou and others thought that they would be trapped in the ancient tomb.

"Excuse me. Do you remember when we were trapped behind an ancient tomb? How did you leave the tomb? The little dragon girl asked.

Although the "Yang Guo" in Tang Xiaosheng's body has not yet woken up. But he was familiar with the novel of "The Condor Heroes" and was no stranger to this plot, saying: "Of course I remember. Then. We stumbled upon a map of the tomb in one of the tombs, and learned that there was a secret passage through which we could exit the tomb. Later, we found the secret passage and dived into a pool, and after swimming through a certain waterway, we finally reached another lake outside the tomb, and we managed to leave the tomb. ”

The little dragon girl nodded, pointed to the basement in front of her, and explained: "Now the overall structure of this basement is very similar to the ancient tomb, so I wondered, since there is a secret passage in the ancient tomb, does this basement also have a secret passage?" Could their secret passages be in the same location? ”

After listening to her explanation, Tang Xiaosheng's heart sank, and he suddenly felt that Xiaolongnu's thinking was still quite divergent, and she was able to think of this problem.

The overall structure of this basement is almost exactly the same as the ancient tomb, so could the location of the secret passage of the ancient tomb also be the location of the basement exit?

Thinking of this, Tang Xiaosheng felt that Xiaolongnu's method was worth trying, and said, "Long'er, do you remember the location of the secret passage of the ancient tomb?" ”

The little dragon girl nodded: "Yes." ”

Since the little dragon girl remembered the location of the secret passage of the ancient tomb and was familiar with the map of the ancient tomb, she could use the map of the ancient tomb to this basement and use the map of the ancient tomb to find the location of the secret passage in the basement.

The little dragon girl's beautiful eyes froze, and while carefully looking around the terrain, she recalled the map in the ancient tomb in her mind, and said: "In the ancient tomb, the position we are standing in now is a circular hall, and through the hall in the direction of the east, we will reach a jade bee room. ”

After speaking, she walked more than twenty steps towards the east, stopped, thought for a moment, and then said, "There is a door to the east of the Jade Bee Room, after entering that door, then turn left, and you will reach a secret room." ”

Before the words fell, the little dragon girl walked more than a dozen steps in the direction of the east, and then, turning left, after walking ten steps, she stopped, continued to recall the map of the ancient tomb, and said, "When you arrive at the secret room, you will find a mechanism on the south side of the secret room, and after opening the mechanism, you will find a secret passage." ”

"After entering the secret passage, you must first walk forward for about 30 meters, then turn right, walk another 30 meters, and then turn right at the last point, and after passing through a narrow path about 100 meters long, you will see a lake, which is the exit from the ancient tomb." ”

Thinking of this, Xiaolongnu continued to walk forward, and after walking 30 meters, she turned around and turned in the direction to the right of Lu, and then walked another 30 meters, and after the last, she turned to the right again and walked forward for a distance of about 100 meters.

After walking, the little dragon girl stopped, pointed to the open space in front of her, and said, "After that, the lake at the end of the secret passage in the ancient tomb is located, and it was from this place that we left the ancient tomb. Perhaps, this place is also our exit from this basement. ”

Hearing this, Tang Xiaosheng stepped forward quickly, staring at the open space pointed by the little dragon girl, his eyes were sharp, and he displayed "Perspective Eye"!

As soon as "Perspective Eye" came out, his vision penetrated the basement floor, and after penetrating a distance of about fifty meters, he saw a body of water!

A dark water.

"There's really an exit here!"

Seeing this, Tang Xiaosheng was overjoyed. In the rest of the basement, "Perspective Eye" could not penetrate, but this small open space found by the little dragon girl could penetrate, and there was no doubt that there was really an exit here.

As long as you perform the "Wall Piercing Technique" and penetrate the formation of fifty meters downward, you will be able to enter a body of water. By then, once out of the water, you should be able to leave this basement.

This is very similar to the situation when Yang Guo, Xiaolongnu and others left the ancient tomb.

Since he found the exit, Tang Xiaosheng immediately called the others over: "Rong'er, Yu'er, Xiang'er, Xiao Zhao, Yu Yan, Minmin, Yingying." Jingjing. Come here, all of you! There's an exit here! ”

Whoosh!

As soon as Tang Xiaosheng finished speaking, thirteen people, including Xiao Huang Rong, Tang Xiaoyu, and Guo Xiang, flew over with lightning speed.

After everyone gathered, Tang Xiaosheng pointed to the open space in front of him and introduced, "Long'er just found an exit here. There is no invisible wall blocking this exit. Therefore. We can get out of here with Piercing Through the Wall. ”

When they heard this, they were amazed and delighted.

Tang Xiaosheng added: "After we use the Crossing Technique to penetrate a distance of fifty meters, we will enter a body of water. The light in the water is very weak. In order to prevent us from getting separated in the water, we are now fifteen of us holding hands and entering the water together. ”

Everyone nodded, and Xiao Huang Rong said, "Brother Jing, I want to hold your hand." ”

"Dad, I'm going to hold your hand too."

Tang Xiaosheng smiled: "Okay! ”

So, Tang Xiaosheng held Xiao Huang Rong with his left hand, Tang Xiaoyu with his right hand, Tang Xiaoyu led Dongfang Undefeated, Dongfang Undefeated led Zhao Min, Zhao Min held Xiaolongnu, Xiaolongnu led Wang Yuyan, Wang Yuyan held Ren Yingying, Ren Yingying held Zixia, Zixia held Gan Nineteen Sisters, Gan Nineteen Sisters held Qingxia, Qingxia led Bai Jingjing, Bai Jingjing led Xiao Zhao, Xiao Zhao led Guo Xiang, Guo Xiang led Xiao Huang Rong.

Fifteen men held hands in a large circle and stood in a large circle above the clearing.

"Alright, let's get ready, we're going to perform the "Wall Piercing Technique" at the same time!"

"Hmm."

After holding hands, the fifteen people looked at each other, their minds moved, and with a whoosh, the fifteen people turned into fifteen afterimages at the same time, and jumped directly under the clearing.

After using the "Wall Piercing Technique" to pass through the nearly fifty-meter layer of soil, the fifteen people successfully entered a body of water.

Crescent Island is located in the Atlantic Ocean, and it is not surprising that Tang Xiaosheng and others will enter a body of water by using the "Wall Piercing Technique" to pass through the fifty-meter soil layer in the basement of Crescent Island.

However, Tang Xiaosheng still found some abnormalities.

It stands to reason that after the fifteen of them only entered the water, they should only dive into the sea area at a depth of several tens of meters, and there should be some light in the seawater.

However, when they entered the water, they were surprised to find that the surrounding area was black, there was almost no light, and they could not see anything clearly in their field of vision, as if they had entered a sea bottom thousands of meters deep.

At the same time, Tang Xiaosheng's clothes are equipped with a miniature satellite navigation device, which can help him quickly identify his current position. As a result, after entering this dark water, which could not be reached, the navigator did not receive any signal, and he had no idea where he was at the moment.

Fortunately, the fifteen of them are holding hands, otherwise, it would be really difficult to find them once they are separated.

Since Tang Xiaosheng and the others had all practiced immortal arts, they were able to provide energy to the human body through the power of their souls and maintain a normal metabolism, so they were able to stay in the water for a long time.

"Supreme Treasure, what kind of place is this?" At this time, Zixia used the power of her soul to sacrifice a sound wave and said.

"I don't know either, the satellite navigator seems to be completely blocked." Tang Xiaosheng also used his soul power to send out a sound wave, "We will continue to use the 'Wall Piercing Technique' now, walk upwards together, and float to the surface of the water as soon as possible." ”

"Hmm."

After speaking, fifteen people held hands and used the "Wall Piercing Technique" to quickly pass upwards together, with a speed of about 500 kilometers per hour.

Tang Xiaosheng and the others thought that it would not take a minute to rise to the surface of the water, but as a result, when they walked together for nearly 20 minutes and rose a distance of about 150 kilometers, they were still in the water!

This result was a source of great puzzlement for everyone.

The deepest sea area on earth is only more than 10 kilometers.

Things seemed a little strange, and everyone became more and more confused about where they were. However, the current situation does not allow them to think too much, and the top priority is to get out of this vast and dark water as soon as possible.

Fifteen people continued to move through at a rapid speed of about 500 kilometers per hour.

During the journey, everyone silently hoped to see the light early and reach the surface of the water as soon as possible.

However, as time passed, all hopes were lost.

20 minutes. 30 minutes, 40 minutes, 50 minutes, 60 minutes......

Time passed minute by minute, and Tang Xiaosheng and the others no longer knew how long Lu Dao had traveled through the waters, let alone how many kilometers Lu Dao had traversed.

The only thing I know is that there is still darkness ahead, and this water is like a bottomless pit of infinite darkness, with no end in sight.

Since I couldn't see the light all the time, I didn't even have a basic sense of direction. Everyone couldn't help but feel a little apprehensive in their hearts.

After all. In such waters, no one knows what awaits them.

"Dad, can't we get out?"

At this time, Tang Xiaoyu asked with a sound wave with the power of his soul. Although there is no end in sight. But she wasn't too scared. Because she was holding her father's hand in one hand. Holding my mother's hand in one hand, I feel very down-to-earth.

"Don't worry, Yu'er. We'll be able to get out. Tang Xiaosheng comforted, although he said so, but his heart was completely bottomless.

They were now just moving upwards by feeling, and it was impossible to determine what exactly was above them, or whether they were heading in the right direction. If the direction is wrong, won't it be the opposite direction?

What's even more terrifying is that so far, they have traveled at least 700 kilometers upward, and they have not yet reached the end, it is hard to imagine how big this pitch-black water is.

If you haven't found the surface of the water, won't you be trapped here?

The thought of such a question can inevitably make anyone feel fearful.

However, Xiaolongnu, Zhao Min, Ren Yingying, Bai Xiaoxiao, Wang Yuyan and other dozen people are relatively calm, not because they are not afraid of death, but because Tang Xiaosheng is by their side now, even if they encounter any accidents, they do not have much regret.

"Duan Lang, are we going in the wrong direction?" At this time, Wang Yuyan said.

"Yu Yan's suspicions are not unreasonable, we have traveled such a long distance in this direction, and still have not surfaced, how can there be such a deep ocean in the world?" Dongfang Undefeated said, "We may be traveling in a direction parallel to the sea level now, so we will not be able to reach the surface of the sea." ”

There was nothing recognizable in the entire water area at all, nor did there be any reference, so Tang Xiaosheng was not sure whether the direction of the journey was right or not, and only chose this direction by instinct. Now that they had traveled at least 700 kilometers through the water and still not reached the surface, he was a little suspicious that they might be going in the wrong direction.

He then said, "Otherwise, let's go in a different direction now." ”

As Dongfang Undefeated said, the direction of travel may be parallel to the sea level, which will lead to the inability to reach the sea surface. Therefore, if you want to change the direction of travel, you should change it to a direction perpendicular to the direction you are traveling in front of you.

However, there is still a very difficult problem in determining this idea. Because in a three-dimensional space, there are countless directions perpendicular to a line, which one is better?

Tang Xiaosheng then asked everyone: "Which direction do you think we should go in now?" ”

Zhao Min said: "We don't know anything about this body of water now, in fact, no one can really say which direction is good, we can only rely on our own intuition." ”

"Then tell me your intuition! It is said that a woman's intuition is very accurate, especially that of a beautiful woman. In order to ease the tense atmosphere, Tang Xiaosheng deliberately joked.

Although Tang Xiaosheng said the topic so easily, the beauties still didn't dare to give their opinions easily. Because if you make a mistake, you may waste everyone's energy. After all, once the direction is determined, everyone needs to expend soul power to travel through.

Seeing that all the beauties were silent, Tang Xiaosheng had no choice but to ask Xiao Huang Rong: "Rong'er, which direction do you think we should go through?" ”

Xiao Huang Rong bent her eyebrows, blinked her big eyes, and glanced around, it was dark here, she couldn't see anything, where did she know where to go through, and said, "I don't know the way." ”

"It's okay, Rong'er can talk about it casually, and it's okay to say it wrong." Tang Xiaosheng encouraged.

"Brother Jing, I really don't know what to do!" Xiao Huang Rong said again.

In desperation, Tang Xiaosheng had no choice but to ask Tang Xiaoyu: "Yu'er, which direction do you think the sea level will be?" ”

Tang Xiaoyu thought for a while, and after a while, said, "Dad, I don't know what to do. ”

It seems that Xiao Huang Rong and Tang Xiaoyu are both honest children, and Tang Xiaosheng will no longer be embarrassed by the two little Lori. He turned to other beauties and asked: "Long'er, Minmin, why don't you point in the direction with your intuition!" ”

Xiaolongnu, Zhao Min and the others remained silent, because their intuition was a bit mysterious and completely untrustworthy. If you say it nicely, it's called intuition, and if you say it ugly, it's called guessing. If you guess the wrong direction, it is tantamount to asking for trouble for everyone.

As a result, everyone did not dare to give their opinions.

"We've been together for almost a hundred years. Why are you all so restrained? Tang Xiaosheng pretended to be relaxed. Don't be nervous, we'll be able to get out of here. Since everyone thinks that the direction of travel may be wrong now, let's change the direction, and you can just say one direction. It doesn't matter if it's wrong. It's a big deal. ”

Listen to him. The beauties still didn't make a sound.

A moment later. Bai Xiaoxiao's thin lips pursed slightly, and then he mustered up the courage to say: "Official, I think the sea level should be in the direction of my left-hand side." ”

"Left-hand side?"

The direction of the left hand side of the white minimum. The direction in which everyone was moving was just perpendicular, so Tang Xiaosheng clapped and said, "Okay, let's change the direction now and walk in the direction of Bai Xiaoxiao's left-hand side." Come, everyone, pay attention, prepare to change direction. After a pause, he ordered, "After I count three times, everyone will change direction together." Three, two, one! ”

Sou!

As soon as the words fell, Tang Xiaosheng and the other fifteen people changed the direction of travel at the same time and moved in a vertical direction.

After changing direction, the group continued to travel at 500 kilometers per hour.

For them, a new direction is a new hope.

Unfortunately, hope turned into disappointment.

When they traveled for 1 hour and covered a distance of about 500 kilometers, it was also dark and there was no light in sight.

When she walked here, Bai Xiaoxiao suddenly felt guilty in her heart, because she felt that she must be pointing in the wrong direction, and said, "Official, I'm sorry, I pointed in the wrong direction." ”

Before Tang Xiaosheng could reply, the little dragon girl had already preemptively comforted: "White girl, don't blame yourself, how can I blame you for this?" ”

"yes, you can't see anything here, it's normal to be wrong. Besides, pointing in the wrong direction isn't necessarily a bad thing. At this time, Zhao Min analyzed, "We have traveled about 500 kilometers in this direction, and still have not reached the sea surface, which probably means that this direction is also parallel to the sea level." As a result, we now know that there are two directions in which the road is parallel to the sea level, and with these two directions, we are able to determine the direction of the sea level. Now that we know the direction of sea level, we can reach sea level as long as we move in a direction perpendicular to sea level. ”

In solid geometry, two straight lines can determine a plane. Tang Xiaosheng and others have tried to travel in two directions in the water, both of which seem to be parallel to the sea level, and the plane formed by these two directions is naturally parallel to the sea level.

In this way, the direction parallel to this plane is the direction to the sea level.

However, at this point in the analysis, there is still a problem: there are two directions perpendicular to a plane, one of which leads to the sea level and the other to the bottom of the sea.

As far as the current situation is concerned, Tang Xiaosheng and the others don't know which direction of the road leads to the sea level, so they can only choose one at random and test it. In case you choose the wrong direction, turn around and travel in the opposite direction.

Once they had made their decision, they changed direction a second time and traveled in a direction perpendicular to sea level.

Since the deepest ocean on earth is only more than 10 kilometers deep, and Tang Xiaosheng and others travel at a speed of 500 kilometers per hour, at this speed, within 2 minutes, they can know whether the direction they chose is right or wrong.

Because if they are going in the direction of sea level, then they have already traveled 17 kilometers in 2 minutes, and they must have reached sea level; Conversely, if they are heading towards the bottom of the sea, they will be at the bottom of the ocean within 2 minutes.

So, if nothing else, in about 2 minutes, things will be clear.

Unexpectedly, the accident happened.

After more than an hour of walking through the waters, they did not reach either the sea level nor the bottom of the sea, and the waters in front of them still did not see any light, and it seemed that there was no end in sight.

When they got here, everyone was a little confused, feeling that this water area was becoming more and more weird, even unreasonable.

They have traveled at least 500 kilometers in three mutually perpendicular directions. It stands to reason that there must be a direction that will allow them to reach sea level. Because even the Pacific Ocean, the largest ocean area on Earth, does not have such a large capacity.

However, after tossing for so long, Tang Xiaosheng and the others were still trapped in the dark waters, unable to find any breakthrough.

The situation is just too scientific.

"Dad, which direction are we going to go now?" At this time, Tang Xiaoyu also seemed to understand the seriousness of the problem, and said with a little worry.

Zixia reminded: "Supreme Treasure, it is not a way to consume it like this. The power of our souls is limited. ”

The situation at hand is a bit bad. This body of water is wider than imagined, and even more bizarre than imagined, and it cannot even be judged and analyzed by the common sense of the earth.

Tang Xiaosheng frowned slightly, it was not a way to try his luck like a headless fly like this. So I tried to do all kinds of analysis in my mind: "This body of water is obviously not a normal space on Earth. Its rules are not the same as those of Earth. It's probably another space. So, what kind of space will it be? We entered the waters from the basement of Crescent Island, don't we...... Is it a virtual ......?"

Then. Tang Xiaosheng's eyes froze, as if he remembered something, and after a while, he suddenly made a decision and said, "Zixia is right, you can't go on like this." So let's pick a direction and go all the way to the end. ”

The beauties discussed it and finally agreed to the plan, and Zhao Min proposed: "Wuji, it's up to you to set the direction!" ”

"Yes, officer, you set the direction! I heard that men's intuition is very accurate, especially the intuition of genius scientists. Bai Xiaoxiao said.

Tang Xiaosheng said quietly: "I think we chose the right direction at the beginning. ”

"Then listen to you and go in the original direction!" Zhao Min said.

Tang Xiaosheng asked tentatively, "Aren't you afraid that this direction is wrong?" ”

"Wrong is wrong, anyway, no one knows the exact direction of the road now, so it's better to gamble." Zhao Min said. She felt that the situation in front of her was completely unclear, that information was very limited, and that the only thing that everyone could rely on was intuition. Although this may seem like a bit of a stroke of luck, it is also an option that has no other choice.

Zixia agreed: "Min Min is right, anyway, we are all guessing, let the Supreme Treasure choose a direction intuitively, maybe he is right." ”

Xiaolongnu added: "Guo'er, since everyone agrees, then it's up to you to decide, we trust you." ”

"Dad, I believe in you too!" Tang Xiaoyu said childishly.

"The eyes of the masses are really bright." Tang Xiaosheng teased, looked confident, and said, "Okay, let's change direction again now and walk in the original direction." ”

"Hmm."

So, at Tang Xiaosheng's suggestion, everyone continued to walk together in the direction they had started to walk.

After hundreds of kilometers, the road ahead was still dark.

However, everyone did not give up and continued to move forward.

In the uncertain future, time passes minute by minute.

1 hour, 2 hours, 3 hours, 4 hours......

Gradually, everyone's concept of time was a little blurred, and they didn't know how many kilometers they had traveled, and they became a little numb.

I don't know how long it took, just when all the beauties didn't have much hope, suddenly, a glimmer of light appeared in front of me!

Yes, there is light!

"Look, there's light ahead!" At this time, Tang Xiaoyu shouted excitedly.

Because the speed of everyone's passage was too fast, in a moment, they had already passed through hundreds of meters of water, and as soon as Tang Xiaoyu finished speaking, the glimmer of light in front of him suddenly became bright!

Seeing this, the hearts of the people were overjoyed, because since there was light, it meant that they were getting closer and closer to the water.

Sou!!

Sure enough, not long after, Tang Xiaosheng, Xiaolongnu and other fifteen people left the water at an astonishing speed, broke through the water, and flew into the air above the water.

"It's finally out!"

"I finally saw the blue sky and white clouds again!"

"Look, there's the sun in the sky!"

……

After flying out of the dark waters, Tang Xiaoyu, Xiao Huang Rong and others all cheered. How could I not be happy to have been trapped in the pitch-black waters for so long, after such a long journey, and now that I have finally left this water?

It's just that when they lowered their heads and looked down at the water below their feet and saw the scenery below, they were all stunned. (To be continued......)
