After a few rounds of the monsters that were jumping down the knife ladder, they suddenly approached and smelled the two of them, then turned around and walked towards the two backpacks that Qingyu threw down, bit the backpack and searched for something inside with their claws.

The monster seemed to have not found what he wanted. Suddenly, he turned his head and looked at the location of the passage, roared, and rushed towards the direction of the passage.

While the giant monster left, the other monsters immediately followed, no longer caring about being in the same place. Tang Qianlin and Li Qingxiang, who thought they were dead.

Li Qingxiang recovered: It’s strange, why didn’t those things bit us to death?

Tang Qianlin already understood: because we don’t have what they want.

Li Qingxiang asked: What? What do they want?

Tang Qianlin looked at the location of the altar: If I was not mistaken, this place was the place where evil spirits used to raise such monsters. The so-called night pearls I saw under the altar were the eggs of these monsters.

Li Qingxiang wondered: What night pearl? What egg?

While packing up his things and checking guns and ammunition, Tang Qianlin explained to Li Qingxiang what had happened before.

After hearing this, Li Qingxiang said: Are the Qing brothers dead?

Tang Qianlin shook his head and said: Anyway, there is so much danger. Let's chase after them to see if they can save their lives.

Li Qingxiang and Tang Qianlin quickly ran towards the direction of the passage. In fact, they were a little uneasy. Because their backpack was bitten by a giant monster, they didn't have much ammunition to carry with them, which was not enough to kill those monsters. Not to mention rescuing the Qing brothers, even the chance of self-protection would be greatly reduced.

After running in the passage for a while, until they reached the wall, neither of them found any traces of the monster and the Qing brothers.

Strange, where is the person? Li Qingxiang looked around, then turned around and looked at the direction he was running. Qingquan was injured, and it was impossible for them to run so fast.

Tang Qianlin stepped forward and touched the wall, and after a long time he confirmed: This is not the path we came.

Li Qingxiang hurriedly asked: Why?

Tang Qianlin pointed to the left side of the wall and said: The edge marks on the wall are completely different from the previous wall. I guess it was deliberately done by the workers who built the here.

After Tang Qianlin reminded him, Li Qingxiang remembered that it was indeed the case. In ancient times, whether it was to build tombs for the imperial family, to build underground palaces for nobles, or even to build secret bases for certain sects, they would leave some marks and secret codes during the construction process. Because they all knew very well what the outcome of this kind of transaction would be, but people had the desire to survive. Even under strict surveillance, they would probably leave some marks for escape.

Li Qingxiang looked around and said: So, there should be another passage. The mechanism is on the wall where we came in. The mechanism of the demon and the goddess will open two different passages respectively.

Tang Qianlin said: That's right, and it's not that the mechanism will be turned on when pressing it, but that it will delay. The purpose of designing this mechanism is to make those who intend to break into this place ultimately unable to leave the altar of care.

Li Qingxiang asked: What does it mean to raise an altar?

While searching for the mechanism, Tang Qianlin explained: Ezesai raises the shamanic demons here, which are the kind of things we saw before. I have seen records before, but because the appearance is very different from the ones in the records, I didn't recognize them at first. It was not until I copied the mural and combined with the content on the mural that I remembered.

Li Qingxiang was shocked and sweated coldly: Demon on earth? What exactly is it? Is it a monster?

No, no, no, I can tell you with certainty that there are no monsters in this world, it is just a strange creature. Tang Qianlin was slowly searching on the stone wall. In the primitive shamanism, this kind of human demon is called "Jekasa". In Chinese, it is "the dragon that can dissolve everything", and is abbreviated as "the corpse-dissolving dragon".

When Li Qingxiang heard the three words "Corpse Dragon" and remembered the Japanese soldiers who were only human skin: This name is very appropriate, where did these things come from?

Tang Qianlin pointed at his feet and said: In the world we live in, there are many things that exist, but they cannot be seen in normal times.

Tang Qianlin looked for a while and shook his head and said: We have to look back and find again. Master Xiang, you go to the left, I go to the right. I search carefully along the stone wall. Logically, the mechanism will definitely be hidden in the soil of the stone wall, and pay special attention to the stone slabs under your feet. Craftsmen usually make marks near the real mechanism, but marking on the soil is not easy, so they can only think of ways on the stone slabs.

In fact, Li Qingxiang, who was once a rushing maker, should have thought of these things, but because he had not experienced these life-and-death moments for too long, his comfortable life, coupled with his panic and loss of mind at this moment, he almost forgot all the professional skills and survival rules in his memory.

Tang Qianlin and Li Qingxiang turned around and walked back, one on the left and the other on the right, carefully searching for the mechanism on the cave wall until they reached the end and returned to the big hole in the altar, but they still found nothing.

Li Qingxiang kicked the hole wall with anger: Where is it! Damn it!

Tang Qianlin stood there calmly thinking, looking around without saying a word.

Suddenly, Tang Qianlin found that the lines on the stone slabs under his feet looked at them slantedly. He squatted down and changed to several angles before looking at the other stone slabs. He found that only one had problems with that one, so he said: Master Xiang, it must be this one.

Li Qingxiang immediately stepped forward and carefully pried the stone slab with a dagger. After prying it open, he saw a stone the size of a fist under the stone slab.

It must be this. Li Qingxiang said and raised his hand and pressed it down. As soon as he pressed it down, he heard a crackling sound coming from under the stone, and then some liquid with white smoke leaked out from the edge of the stone.

Be careful! Tang Qianlin pushed Li Qingxiang away with one palm, and Li Qingxiang fell to the ground, and the stone slowly fell and returned to its original state.

Li Qingxiang saw the smoked liquid and swallowed: It was a strong acid

Tang Qianlin nodded: That's right, if you continue to press down, the strong acid may erupt. Even if you don't die, your hands will be finished.

At this time, dense gunfire came from behind the wall, and the monsters could still be heard.

Li Qingxiang walked to the cave wall on the right with a sound, fired at the cave wall with a gun, and kicked it a few more times: It was obviously close at hand! I just couldn't find the real mechanism.

Calm down. Tang Qianlin pointed at Li Qingxiang and said in an almost commanding tone that the more you are, the more calm you should be. Senior, now carefully recall what you looked like and what your mentality was when you were most energetic back then, calm yourself down, and then think about it carefully, what we missed.

Li Qingxiang took a deep breath to calm himself down, but for some reason, the shadow of Ye Feng was shaking in front of him at this moment. He shook his head hard and shook all the fragments away.

After a long time, Li Qingxiang suddenly said two words: mark.

Tang Qianlin was puzzled: Sign?

Li Qingxiang said: That's right, you just said that craftsmen will mark the floor, so our attention is all on the floor, thus ignoring other things. Think about it, the people who designed the place here are so smart, how could he not know that craftsmen can do things?

Tang Qianlin immediately understood: You mean, there will be a mechanism for the reverse?

That's right. Li Qingxiang looked at the stone under the stone slab. Maybe this is the mechanism of turning back. Let's try again.

What is a mechanism that is a mechanism designer. He knows very well that during the process of making the mechanism, people will make marks. He deliberately pretends to be unaware of it. After the mechanism is completed, he quietly resets the mechanism.

The reason why the mechanism is designed is to prevent outsiders from entering or trapping the intruder. Since the object is human, then people will think. The ultimate goal of the real mechanism is to disrupt people's thinking and seize your psychological blind spots tightly.

The same is true for the reverse mechanism. The designer will reset the mechanism that makes the mark. On the surface, it seems to be a harmful trap, and also makes the person who discovers the mark realize that it is a trap, which creates the illusion that this is not a real mechanism, and directly gives up here and go to a dead end.

Tang Qianlin stood in front of the stone and signaled Li Qingxiang to get out of the way: Master Xiang, I will use the phoenix gun to hold the stone, stand away.

OK. Li Qingxiang no longer insists. If there is really strong acid spray, even if one person is injured, there will be another person left.

When Li Qingxiang retreated, Tang Qianlin pressed the stone directly with the end of the phoenix spear, and then used a little force.

Strong acid immediately seeped out of the edge of the stone. As Tang Qianlin exerted his hands, the more powerful acids penetrated, and there was a tendency to eject from the edge.

Stand away again! Tang Qianlin stared at the edge of the stone and shouted.

At this moment, Tang Qianlin was still worried about him, which made Li Qingxiang very moved. He once again thought of the adventure he and Ye Feng back then. When did he be like the man in front of him?

Next, something unexpected happened between Tang Qianlin and Li Qingxiang. Not only did strong acid seep out of the ground, but even the walls began to slowly seep out of unknown liquid.

Li Qingxiang looked at the gradually broken wall and shouted at Tang Qianlin who was still insisting on it: Don’t hold on, let go quickly, you will die!

Tang Qianlin never let go: it's almost over.

Li Qingxiang was anxious: This is not a reverse mechanism, this is a trap, don't hold on, don't

As soon as he said this, the wall on the right was completely broken, and a large amount of liquid with an extremely fishy smell rolled out from it, directly eroding Tang Qianlin. Tang Qianlin also lost his balance and fell to the ground, wrapped in the liquid and rushed several meters away.

It's over. Li Qingxiang was stunned and looked at Tang Qianlin who was motionless in the distance, his mind was blank.

At this moment, Tang Qianlin, who was soaked all over, got up, raised his hand and smelled his arms, and grinned: It's okay, it's just ordinary sewage.

Seeing that he got up and was smiling, Li Qingxiang breathed a sigh of relief and shook his head and said: It seems that it is really a reverse mechanism.

Tang Qianlin looked at another passage opposite the broken wall: Yes, it was the reverse mechanism.
Chapter completed!
