In the process of taking the "ancient elevator", Li Daoyi suddenly sighed: "Hey! After tossing and turning for a long time, let's go back to the original path......"

"Not really!"

Liu Ru shook her head and retorted: "According to the direction of the passage, we should be here ......"

As she spoke, she took out the neatly folded "Sheepskin Scroll" from her coat pocket, spread it out in front of Wei Zede, Li Daoyi, and Liu Kai'an, and pointed to the map printed on the back of the scroll.

"Liu Yatou (Liu Ru), why did you take out this map?"

Wei Zede and the others were angry for a while, if they could see this map earlier, everyone wouldn't have to run around like headless flies.

"I just remembered!"

Liu Ru's answer was very crisp, and there was no trace of sincerity.

Shaking their heads, Wei Zede and the others leaned their heads to the map and looked at them carefully.

Under Liu Ru's guidance, Wei Zede noticed that at this time, they were in the center of the "Seven Star Disk Dragon Lock Demon Array"!

Based on the information obtained from the "Parchment Scroll", Professor Liu Kai'an believes that the place where the people are about to arrive is an "ancient altar" carved into the rock formations of the mountains, and the passage to the legendary "Great Xianbei Mountain" is located here.

"This Lost City (Da Xianbei Mountain) is really mysterious......"

Liu Ru said with emotion: "Maybe only after going through hardships and dangers and overcoming ninety-nine eighty-one difficulties...... Only those with great perseverance and wisdom can find this lost city! ”

"Great perseverance? Great wisdom? I don't care about any of that, all I care about now is how to make it to the end of the mission! ”

Wei Zede and Li Daoyi glanced at each other, and both of them could sense the worries in each other's hearts.

With a "clang", the group of people left the underground passage full of miserable green fire and entered a new space with the rising bluestone slab.

"Who is it? Speak! ”

At this moment, a very nervous shout came from the darkness!

Wei Zede and the others were stunned when they heard this, isn't this the voice of Captain Zheng Hongzhi? How did he end up here?

While Wei Zede was pondering, Li Dao responded loudly: "Is it Captain Zheng?" I'm Li Daoyi! ”

The pillars of light emitted by the two "wolf eye" flashlights immediately turned to the direction in which Li Daoyi spoke.

"It's really Comrade Li!"

"They didn't die ...... either"

“……”

With the sound of noisy footsteps, several vague figures approached from the darkness.

"Captain Zheng, what's wrong with you? What about the others? ”

Seeing that Captain Zheng and the others were injured, Professor Liu Kaian asked again and again.

"Others?"

Zheng Hongzhi was obviously relieved after seeing Wei Zede and the others, and he replied: "There are no other people, there are only these few people left in our rescue team......

The atmosphere was very solemn.

"Don't be discouraged, everyone! Even if we can't complete the mission, we still have a good chance of getting out of here alive......"

After hearing Professor Liu Kai'an's words, the spirits of Zheng Hongzhi and others were lifted.

"Old Liu, are you saying that we can still get out alive?"

"That's right!"

Professor Liu Kai'an nodded affirmatively: "That 'parchment scroll' is on Liu Yatou's body...... I believe that as long as you can follow the instructions on this map, you will be able to leave here! ”

At Professor Liu's suggestion, Liu Ru unfolded the "Parchment Scroll" again.

Pointing to the map engraved on the back of the scroll and the location marked "Altar" on the map, Professor Lyukaean explained to the crowd: "Look, we are in this place now—the altar!" ”

"And the passage out of here is in the center of the altar......"

Looking at Zheng Hongzhi, who looked a little excited, Professor Liu continued: "As long as we find this passage, we can leave this underground space!" See the light of day again! ”

"Good!"

Captain Zheng Hongzhi patted his thigh and said excitedly: "As long as we have a clear goal, we will have hope and motivation to do things!" ”

"Don't say nothing, it's all about living!"

After a short break, Zheng Hongzhi and everyone embarked on the journey again.

"Captain Zheng, it stands to reason that the state should also provide our rescue team with a copy of the Sheepskin Scroll, right?"

Walking on the road, Wei Zede asked Zheng Hongzhi.

Zheng Hongzhi shook his head.

"I know a little bit about this!"

Liu Ru explained for Captain Zheng: "I don't know what kind of material this parchment scroll is made of...... After the professional instrument test of the Chinese Academy of Sciences, the conclusion is unknown! ”

"Unknown? What does that mean? ”

Professor Liu said, "What Liu Yatou means is that this ancient scroll can be confirmed to be made of leather, but experts can't determine the type of leather!" In other words, the origin of this skin is an unknown creature that has never been seen before. ”

"I don't know where the leather comes from...... Is that still called 'sheepskin'? ”

Li Daoyi pursed his lips: "These things you are talking about don't seem to have anything to do with the state providing 'copies' to the rescue team, right?" ”

"It's related!"

Liu Ru continued: "It was the 'leather' factor that further contributed to the fact that the parchment scrolls could not be rubbed. ”

"Photography, memory, hand-drawing...... We've tried all of them, but none of them work! ”

Professor Liu bowed his head and said, "Yes! I tried to draw a map by hand, but when I was done, I realized that the hand-transcribed content was very different from the 'parchment scroll'! And when it comes to photography, the washed out negatives are blank and nothing! ”

Wei Zede and the others nodded, accepting this explanation.

Unlike the others, they couldn't remember everything on the Sheepskin Scroll, but Weizel did remember it vividly...... After thinking about it, he didn't tell anyone about the situation.

"Judging from the information recorded in the ancient scrolls, this altar is connected to three passages, two in and one out."

"Zheng Hongzhi and they should have taken the top-down passage, and I and Li Daoyi, Professor Liu, and Liu Ru walked the bottom-up passage."

"And the remaining passage must be the exit to the 'Lost City (Great Xianbei Mountain)'......"

Just as Wei Zede was recalling the map information on the back of the scroll, there was a sudden "click" sound under his feet! This made his whole body freeze all at once.

"There's a trap! Don't move, everybody! ”

While warning him, Wei Zede took the "wolf's eye flashlight" and shone it under his feet.

Everyone immediately calmed down and watched Wei Zede's movements.

"Whew! It's good that it's not a ......."

When he saw clearly that he was stepping on a white bone, Wei Zede exhaled.

"It's okay! It's just a bone, let's keep walking! ”

Everyone else breathed a sigh of relief, and no one blamed Wei Zede for making a fuss, and in their opinion, such a cautious behavior was very necessary.

"Strange! How can there be bones here? ”

Professor Liu crouched down, picked up the broken bone that Wei Zede had stepped on, and examined it carefully.

"Wait a minute!"

Professor Liu Kai'an's face changed suddenly, and he pointed to the white bone in his hand and said, "This is a human bone!" You'd better stop and search to see if there's anything else you find! ”

Under Zheng Hongzhi's arrangement, everyone divided into several groups and searched to the left and right sides and the front.

"There's a lot of corpses here!" Captain Zheng's voice came from the left.

"There's it too!" Lee Do-il's voice sounded on the right.

"Front...... There are also a lot of bones in the front! Lieutenant Du Xuyao, after probing the front, also loudly reported his discovery.

"Captain Zheng, do we still have flares?" Wei Zede asked loudly.

"Yes! But that's all there is to lose! ”

"Then use it, don't keep one!"

With two flares lifted into the air, the Abyssal Altar was revealed in its entirety to everyone's eyes.
