The cave was full of water, which was surprisingly clear and smellless without seeing the light of day.

Now.

There are small fish that are not afraid of people swimming under their feet.

Now he doesn't need Yun Youyou's guidance, Lin Dong can also sense the location of the mechanism that is opened. On a stone wall in the southeast, there is a huge ** array hidden inside. The upper part of it, out of Lin Dong's height is several meters, and the lower part is half-hidden underwater. Lin Dong came to the waterline, and a mark specially carved by his predecessors was inscribed on it.

"Is there a way?" Yun Youyou said that the focus of the mechanism should be pushed underwater, and if Lin Dong is not used to it, then it will be opened by her.

"Is this the door you want to open?" Lin Dong felt that it was not too easy to open this.

"It's not. Yun Youyou shook his head, indicating that this was just the beginning.

"Okay!" Lin Dong was suddenly very confident now. What he imagined was that if it were all like this, it would be difficult to get there. Unlike Yun Youyou's cognition opening method, Lin Dong didn't use his power at all, and he didn't even push this mechanism. In fact, the principle is the same, Wu Xiutong guò's own energy pushes the mechanism, touches the guardian array, meets the requirements, and then passes guò. Like Lin Dong, he gathered the energy of heaven and earth and injected it into the formation behind the stone wall, as long as the minimum requirements were met, then no matter what method it was, the mechanism would be automatically activated.

Buzz Buzz Buzz ......

With the injection of Lin Dong's energy, there was a tremor in the array inside the stone wall.

The guardian circle left by the predecessors woke up from its slumber, it has no spiritual sense, it can't distinguish between good and evil, and it doesn't matter who opens it, but there is a basic law of guardianship, and the person who touches it must meet the standard, otherwise it can't be opened.

The stone wall gradually showed up with light, faintly forming a array.

Arranged in five rows.

The five formations of metal, wood, water, fire, and earth were gradually connected, and finally connected together, and with the help of the heaven and earth energy injected by Lin Dong, it was officially revived.

At the peak of the light, the stone wall where the Five Elements Array is located rotates clockwise according to the circle of symbiosis, and the huge kinetic energy drives the internal organs, and in the rumbling roar, the stone wall Taiji Yin and Yang fish spin to both sides, revealing a huge circular cave with a diameter of more than ten meters. At the moment of opening, a spiritual wind rushed to the face, turning into energy and floating around, filling the entire cave space, more into the water before the Five Elements Stone Wall, and the small fish living in the cave immediately rushed over like a tide, scrambling to swallow it.

The light of the Five Elements Array gradually disappeared, and only a small light cluster that should be used to keep time was left, still flickering faintly.

Two and a half hours.

After Lin Dong carefully sensed it, he came to the conclusion that the time limit should be about five hours.

If you are still stranded, the stone wall will automatically reset and trap the entrant.

"Ah, your opening degree is so fast?" Yun Youyou was so shocked when he was a child, he was so stunned that he had forgotten the time it took for his master to open it before, and he couldn't make an accurate comparison with Lin Dong's now. However, even if the opening time was about the same, she felt as if the master had to work harder, and it was not as easy as Lin Dong to open it. He didn't have to exert any effort at all, and it seemed that he could open the stone wall easily.

"It's slow, isn't it!" Lin Dong estimated that it would not take ten seconds to open the mechanism of this five-element magic circle before the time crossing and returning.

"Don't you need to use force at all to open the mechanism?" Yun Youyou suddenly became a little curious about Lin Dong's cultivation.

"...... hard" Lin Dong had to patiently explain to a curious martial arts girl: "I use another force, the energy of heaven and earth, the same as you push it hard, and it's not easier than you, don't you see that I'm about to tire into a dead dog? It looks fine on the surface, but in fact it's not so easy!"

"It doesn't look like it!" Yun Youyou didn't see it at all, and he couldn't sweat a drop to be tired and a dead dog?

"Ah, if there are a few more stone gates like this, I will become a human being, can you understand this explanation?" Lin Dong gave an example to illustrate, but unfortunately Yun Youyou's sister still shook her head.

Or maybe she already understood.

It's just that I can't see this kid's appearance, so I deliberately pretend to be stupid and tease him, so as to save him from being too proud.

There is a passage in the stone wall cave, about 20 meters forward, there are artificially carved stone steps continue to extend upward, about 50 meters or so, and turn down, so up and down, twist and turn, go around the mountain, about a few kilometers forward, there is a platform in front of Lin Dongxian, who walks in front of him with a flashlight. There are stone tables and stone benches on it, and it seems that someone has lived here.

It's a pity that the items inside have been emptied by the predecessors, and even the words engraved by the original owner have been scraped and destroyed with sharp blades.

Lin Dong turned around and looked at Yun Youyou: "The black jade gourd was picked up here?"

Yun Youyou shook his head.

Yu pointed to the dark place in front of him: "Far away, there are two doors in front, and there is a sword platform in the distance, that is the 'door' that really needs to be opened!"

Sword platform? Lin Dong's heart was slightly shocked when he heard this, could it be the sword platform that the Dragon Slaying Daoist left to seal the dragon? If it is true, then it will be reached!

The two crossed the platform and continued onwards.

After about two kilometers, I saw a huge stone wall blocking the way.

"Let me open it this time!" Yun Youyou took the initiative to ask, her heart was unbearable, she was afraid that Lin Dong would really run out of energy and become a human worker, after arriving at the second layer of the stone wall, she decided to take action in person and share the task.

"Don't!" Lin Dong's eyebrows jumped lightly, and a not-so-good premonition came to the bottom of his heart.

He felt that behind this stone wall, there might be a mountain guard beast or something like that, and it wouldn't be as smooth as it was just now.

In the Xiuzhen Cave Mansion, it is inevitable that there will be fierce beasts guarding it, otherwise if you go out to the house and let the thief empty it, then the face of the cultivator can still be wanted? Whether it is a panacea, a magic trick, or a rare treasure, these things are not allowed to be touched by outsiders. Some cultivators are powerful, and their skills are incomparable, and they can expand the entire cave mansion into Lingshan Immortal Island, the big one is comparable to a big 6, there are not only guardian beasts on it, but also disciples and their vassal races, thousands of people live in it, it is like a country outside the sky.

Generally speaking, cultivators with the level of the head sect master can rest assured, they don't need to worry about the cave mansion being invaded, unless the sect is destroyed, their cave mansion is safe.

Or the Futian Cave Land, or the Meditation Secret Realm, located in the sect he founded, and guarded by a special person.

There are also those who are solitary laymen, and there are no disciples to protect them.

Then release some demon beasts around the cave.

Instead of guards.

First, to avoid being disturbed by outsiders, and second, to get it when needed, without having to go out to hunt and kill.

There are also some monks who are particularly kind-hearted, and they will live in the company of certain fairy creatures, so that they can communicate with each other and take what they need.

"There is a cold aura behind this door!" Lin Dong looked at Yun Youyou strangely, and hurriedly told her to be careful: "It may be some monsters, or it may be the mutated descendants of the Mountain Gate Guardian Beast." Be careful, because these things are imprisoned, their whole lives and cognitions are distorted, often bloodthirsty, only killing instincts, without a trace of kindness. ”

"I've been in there, I know a little bit about the situation, you're right, there are a lot of big snakes in there, and there are a lot of weird insects that look very ugly......" Yun Youyou looked at Lin Dong with big eyes, suddenly smiled, and covered his mouth with joy: "These things are very bullying and afraid of hard, as long as your strength is far away, they generally won't provoke you." Still, thank you for the reminder, hehe!"

"I'll open this door, you save your strength first, in case you can't beat it, let's run." "Lin Dong always thinks about the consequences first, and does not fight uncertain battles.

It's not impossible for the cloud to come and open.

If you are not afraid of 10,000, you are afraid of what happens.

If you are unfortunate enough to encounter an ancient monster that has just awakened from its slumber...... Lin Dong had not encountered this kind of thing before, the entire team, the large team of twenty-five monks, except for Lin Dong and his companions who were extremely good at hiding under the Moon Shadow Sect who escaped, the other twenty-three people were all wiped out. At that time, Lin Dong's strength in the team was not ranked in the top ten, and he was able to escape because of his premonition on the battlefield and his caution. To this day, Lin Dong still feels chilled when he thinks about it.

In the course of the expedition, any mistake in every detail, any period of carelessness, may lead to death.

Lin Dong was tired.

You can also absorb the spirit stone to restore the fù, and the impact is not great.

As a martial cultivator, if Yun Youyou is tired, it will directly affect his combat effectiveness!

Inside the second stone wall is the reverse Five Elements Great Array, and the opening process is more dangerous than the first one, but fortunately, Lin Dong is familiar with these Five Elements Formations that belong to the general formation in the Xiuzhen world, and it is not too difficult to solve, and the energy consumed is not very much.

The stone wall rumbled open.

There is a kind of yin qi like a poisonous mist, which permeates from within, and if it is an ordinary person's will, it will definitely be affected by it, or fanaticism, or fear, or anxiety, in short, all kinds of negative feelings will come to the mind. Lin Dong kept his mind, walked slowly through the passage, looked left and right, and now the second stone wall is directly opened in the middle of the cliff, and below, is the underground dark river formed after the mountain breaks.

Lin Dong slowly descended along the slippery stairs, and before there were two hundred stone steps, a dark river as black as ink appeared in front of him.

"The right side is blocked, and we go to the left. Yun Youyou was about to lead the way, suddenly, she saw that Lin Dong had a treasure map in her hand, and when she looked at it under the flashlight, it was no different from this underground dark river, and there were some secret locations that she didn't know, and she suddenly sweated for it, where did this come from?

"Are you really cute like this?" Lin Dongxian, this girl's courage is even greater than the sky.

Shirtless and dressed in a tracksuit.

I don't have any half of the talisman treasure on my body, so I dare to come in and explore and hunt for treasures...... Hey, can you be a little more female? Laura from Tomb Raider, at least they have a pistol!

Yun Youyou glanced at him.

said that he begged not to say it if he knew that he didn't, so it made people feel very stuffed!

In the dark river, several giant pythons with a body length of more than twenty meters were lying lazily in the river, some hanging between the river stones and pretending to be dead, and some simply twisted on their companions' bodies, twisted together in a mess, they turned a blind eye to the arrival of Yun Youyou and Lin Dong, and there was no abnormal reaction at all. Yun Youyou walked on them very calmly, constantly jumping forward with the help of the river stones or bodies next to them.

Lin Dong looked at it.

Full of rainstorm pear blossom sweat!

Because of the relationship between wearing the jade pendant, although she didn't know how to use it, the creatures in the dark river instinctively gave birth to a sense of awe.

Yun Youyou didn't hurt them, they didn't dare to resist at all, and let her trample her body forward.

Lin Dong not.

As he walked past them, the pythons looked wary and looked up at him, until they sensed that the aura emanating from him was strong and domineering, far superior to himself, and quickly dismissed the idea of a full meal, and resumed his original lazy appearance of pretending to be dead.

There are giant pythons in the dark river, and the banks or cliffs are crawling with strange-looking lizards, each five or six meters long, and their bodies are larger than crocodiles.

When Lin Dong was observing himself, they were also looking at this strange human being.

Some even chased him and crawled for some distance.

Lin Dong walked forward a little further.

From time to time, some strange insects that look like centipedes and a bit like lobsters will emerge in the dark river, with huge individuals and tails about two or three meters long, and their appearance is particularly ugly. One of them didn't open his eyes, thinking that Lin Dong was delicious food, and tentatively stabbed him with a chelicerae with a sharp barb.

"Look for death!" Lin Dong flew up violently.

Blasts the entire head of the monster worm.

Blue blood and countless fragments of stumps flew into the sky, and the body of the headshot monster was still not dead, and it struggled in the dark river for a long time, until its companion took advantage of the weakness and dismembered its body to eat, and its life was truly over. Yun Youyou stood on a river rock, stopped, and looked back at him: "I came here when I was nine years old, and I didn't have any insects to bite me, so you must have a bad character!"

Lin Dong really wanted to tell her, you take off the jade pendant and try it, it's strange that those insects don't announce the start of the meal!

The words rushed to his lips, but in the end he still didn't say it.

It should be for the sake of the black jade gourd.

Yun Youyou's sixth sense is strong, and when he saw that he was a little unhappy, he understood what he meant, and he couldn't help but have countless apologies in his heart: "Lin Dong, it's my fault to put you in danger, if it's really dangerous, then let's go back, I can't let you take risks just because I want to fulfill Master's wishes." ”

"Forget it, I've already come here, don't say it's okay, it's just that there are really swords, mountains and fires in front of me, and I have to break through. Lin Dong hurriedly comforted her.

I just finished saying that.

In the distance, two kilometers away in the dark river, a huge head suddenly rose, hideous and terrifying......
