The experience between life and death several times made Chen Ziyang's mind unusually clear, especially when such a strange thing happened. Chen Ziyang's brain was running rapidly.

The passage here is not bifurcated, and the front and back of the passage are the same width, so it is impossible to have the kind of optical illusion fork in the shallow water fish dragon, and at the same time, there is no ghost hitting the wall here, and the direction of the passage is really changing.

Excluding the above two points, then there is only one possibility, this channel is rotating in its own direction, but it is relatively stable when it rotates, so everyone does not feel it.

Thinking of this, Chen Ziyang found one of the most fatal loopholes in this mechanism, that is, there is no magnetic interference here, and the compass and compass can accurately indicate the direction here.

As long as you have something that can point you in the right direction, it won't be difficult to crack the mechanism. Now Chen Ziyang only needs to put the compass firmly on the ground and pay attention to the direction of rotation of the compass pointer to find the law of the rotation of this channel.

After figuring out the laws of the rotation of the passage, you only need to send a few people to walk forward along the passage to find the boundary of the mechanism. Any mechanism that turns in this direction has a limit and does not turn the whole world around.

So as long as you find the rules and find the boundaries, then it will be easy to crack this rotating mechanism and get out of this changing channel.

In the tombs of the shallow water fish dragon and Li Yan before, there was the interference of magnets or iron ore and other things, which caused Chen Ziyang's compass to be unusable, so it was impossible to crack the mechanism inside, if the compass could be used at that time, Chen Ziyang would easily discover the secret of the optical illusion in the shallow water fish dragon.

Just when Chen Ziyang wanted to put the compass on the ground and monitor the changes in this passage, he suddenly reacted, someone who can design such an ingenious mechanism will definitely not ignore such an important thing as a compass.

"Be careful, everyone, there may be a mechanism nearby." Chen Ziyang hurriedly reminded.

"A large amount of unidentified smoke and dust gas has been found in the rear, which is approaching us at a very fast speed." Not long after Chen Ziyang's words were finished, the flashlights of the two team members in charge of the broken rear of the team shone on the entire passage, and a piece of flour-like thing rushed towards them.

Fortunately, thanks to Chen Ziyang's reminder, Xiao Na immediately reacted as she should have been. "Move quickly and dodge the dust."

That's right, this is the effect that this organ should play, Chen Ziyang thought in his heart, if he let others know that he was thinking like this in his heart, he would have to scold him. Hit someone else's mechanism, seeing that the deadly things were all pounced, not only did he not know that he was in a hurry, but he was also admiring the ingenuity of other people's mechanism design.

Now Chen Ziyang has completely figured it out, the reason why the compass can be used in this underground palace is that it is estimated that if you want to crack the mechanism here, you will definitely use the compass, so that the person who takes the treasure later can have the ability to crack the underground palace mechanism.

The person who designed the dungeon should have something other than the golden gear to keep track of how to crack the mechanism in the tomb, but these things didn't reach their own hands. Moreover, when cracking the tomb mechanism, it is necessary to use the compass, so there will be no magnetic things around the dungeon that affect the use of the compass.

And the reason why there is no such dust-like mechanism for attacking people in the first passage they enter is because it is the first passage, whether it is a person who strays into this underground palace or a person who really comes to collect treasure, they will pass through the first passage.

So there won't be any mechanism in that passage, but in the same way, although Chen Ziyang and the others had the opportunity to observe the transformation of the passage in that passage, they missed this opportunity because they didn't find anything strange about this passage at that time.

Now, due to the change in the second lane, the team may have entered the wrong lane. And the person who can enter the wrong passage is definitely not the treasure hunter of the Bohai Palace. Therefore, they must be greeted here with all kinds of killing moves, and this kind of killing moves should be one after another, so that the people in the passage will not have the opportunity to use the compass to crack this mechanism.

Chen Ziyang, who had figured all this out, knew that the agencies behind him would come one after another, so he reminded everyone to be careful of the surrounding organs. But then he realized that his reminders were useless.

Because the smoke behind it came too fast, forcing everyone to move forward quickly, at such a speed, any mechanism can only go head-on, there is no way to be careful.

Now Chen Ziyang didn't have time to look at the change in the direction of the pointer on the compass, and he didn't know if the passage had changed again. This kind of mechanism is really cleverly designed, and when the passage changes direction, the people standing in the passage don't even feel it at all.

Although he is now in a fantasy realm, Chen Ziyang has no sense of fear, because Xiao Na's team is really outstanding, all the people are uniform, and no one is panicked because of fear, which also makes Chen Ziyang and several others feel relieved, and at the same time stimulates their own potential.

But what Chen Ziyang feared finally happened. Just as the team was running wildly, all the people suddenly noticed that a stone wall appeared in front of them, and this passage had already run to the end!

On that stone wall, there was a hideous sculpture of the beast's head, because it was dark in the passage, and the people in the team did not see what the beast head was.

As soon as you look at the stone wall in front of you, everyone in the team knows that it is not good, so that the dust behind will immediately rush into the team. Everyone subconsciously looked back, but was surprised to find that the dust that had been chasing behind them suddenly disappeared without knowing when.

"Be careful!" The soldier at the front of the line shouted, pulling the trigger in his hand. The weapon in his hand slammed something out.

Chen Ziyang hurriedly looked back, and when everyone turned their heads to look at the smoke behind them, only this soldier was still sticking to his post, still staring at the front. And then he found that just now, the beast head on the wall seemed to move, so he subconsciously used the weapon in his hand, which is also a habit he has developed for many years, and it is already a conditioned reflex.

The weapon in the soldier's hand was not a gun, but a very thick but short iron bucket-like thing, Chen Ziyang had seen this weapon before, and thought it was some kind of small hand-held cannon or something, but what was fired from the weapon in the soldier's hand was a net, a net woven with steel wire.

This huge net is square, and there is a nail-like thing at the four corners, and under the huge firing force, this steel wire mesh flies forward and opens quickly, and at the same time, the steel nails at the four corners are nailed out in four directions, and they are firmly rooted into the stone wall of the passage and fixed.

And because the anti-shock force of the launcher was too great, the soldier was shocked to fly backwards after firing the steel wire, fell into the crowd, and reluctantly stopped after knocking down two people.

After the net was opened, everyone heard a crackling sound, and it turned out that countless crossbow arrows were shot at the net, but they were stopped by the net made of steel wire.

Although the soldier who fired the net reacted quickly and made the right choice the first time, he was a little slower, and two crossbow arrows passed through the net on the side before the wire mesh could be fully opened, piercing into the ranks behind him, and digging firmly into the neck of one of the soldiers.

The soldier wanted to shout but couldn't make a sound, so he could only cover his neck with his hands, and then everyone realized that this kind of crossbow arrow was not an ordinary crossbow arrow, it seemed to be something like an iron pipe, and it turned out to be hollow.

The crossbow bolts pierced the man's body, and blood spurted out from the back of the bolts, and two long pillars of blood announced the soldier's death.

In front of everyone, the crossbow arrows were still shooting at the net, but fortunately the net was relatively strong, and the four corners were fixed relatively firmly, so that not a single crossbow arrow penetrated, and the smoke and dust behind it were all gone.

It is very rare, now that everyone is in a safe area, Chen Ziyang didn't care about anything else, quickly took out the compass and put it on the ground, and observed it carefully.

Xiao Na led the team, still closely watching for any other movements in the front and back directions of the passage. After a few minutes, no more crossbow arrows were fired from the wall carved with the sculpture of the beast's head. And there was no more smoke and dust behind the passage.

Seeing that the people in the team were temporarily safe, Xiao Na ordered everyone to take Chen Ziyang as the center and divide into two directions to protect him, and at the same time arranged for several people to take turns to stand guard, and the others rested as much as possible while protecting Chen Ziyang.

Looking at Chen Ziyang's focused eyes, Xiao Na knew that it was up to him whether she could get out of this changing passage or not.

While carefully observing the compass and recording something in detail on the paper beside him, Chen Ziyang was so focused that he didn't care about the changes around him at all.

At this time, a scream suddenly sounded in this passage, and it was only at this time that Umbrella Shishuai realized that he was still clutching the two wings of the bat in his hands, and the bat was still alive.

Idle and nothing, Umbrella Shi Shuai hurriedly studied this bat, the size of the bat is very huge, the wingspan is also very long, and at the same time, on the four claws before and after the bat, there is a claw with a very long tip, and very sharp, I think it was these claws that attacked the people in the team, so that everyone was slightly injured.

The bat suddenly stretched its head forward, sticking out two long fangs from its mouth, which looked very similar to the vampire bat in the cartoon.

These two fangs grazed Umbrella Shi Shuai's wrists, almost causing him to hurt him again, looking at this bat, Umbrella Shi Shuai was angry, reached out and took out the sapper shovel, and slapped it on the bat's head at once.

Not only did he knock out one of the bat's fangs, but he also smashed half of the bat's head, and the bat's body was thrown to the ground, already dead.

A few hours passed, Chen Ziyang raised his head and turned his attention to something else, he needed to rest his brain.

Because these few hours were very torturous for him, Chen Ziyang originally thought that by taking advantage of these safe times, he could understand the law of the change in the direction of this passage and find out the cycle of the passage change, which would help to crack the mechanism of this channel.

But in the course of a few hours, the passage did not change again. At the beginning, Chen Ziyang thought that his compass was broken, but looking at everyone's watches, it was still the same, which made him confused, could it be that the previous guesses were all wrong!

Looking at the huge steel wire fence standing in the passage, Chen Ziyang thought of two things, first, the professionalism of Xiao Na's team was beyond his imagination, this weapon seemed to be specially designed to deal with the crossbow arrows in this square passage.

Once fired, four steel nails are fired in four diagonal directions, and the nails are firmly embedded in the passage, so that the net is completely opened.

But fortunately, the width of this passage is not very wide, and the height is not very high, otherwise the net would not work.

At the same time, Chen Ziyang looked at the stone wall where the crossbow arrows were fired, this mechanism was very cleverly designed, everyone was chased by those smoke and dust, and suddenly found that something was blocked in front, and all of them would subconsciously turn around and look behind to see where these smoke and dust had been chased, and they had no chance of survival.

At this moment, the crossbow arrow will shoot from the back of the person, making it impossible to guard against it. If it weren't for the soldier who stuck to his post, such a powerful crossbow bolt, and at the same time so many of them, and they were shot from behind, everyone would have turned into hedgehogs.

What gave Chen Ziyang the most headache was that his guess of the mechanism here was completely incorrect, the person who designed this underground palace was really a master, an absolute master.

Soon it was time for lunch, and the people in the team began to simply replenish some food, because they were trapped in this dungeon, there was no follow-up supply, and everyone didn't know when they would be able to go out, so Xiao Na strictly limited the amount of food that everyone could eat.

Everyone in the team was allowed to eat only one compressed biscuit and drink two hundred milliliters of water at the same time. Wang Dawei threw a small piece of salt into everyone's water to replenish their strength.

Looking at the dead huge bat on the ground, Wang Dawei smiled, then took out the dagger on his body and chopped off the bat's head at once.

Chen Ziyang and Yang Lei were taken aback by his actions and didn't know what he was going to do, and then Wang Dawei skillfully cut open the body of the bat with a dagger, and cut a few pieces of meat inside, and he actually wanted to eat the bat.
