With the strength of the three people in one place, the iron chain was slowly pulled, and a series of clanging sounds filled the entire stone room.

At the beginning, the iron chain was very jerky, and the three people needed to use a lot of strength to pull a little, but as the iron chain was pulled out longer and longer, it was no longer necessary to use too much force to pull the iron chain.

When pulling the iron chain, Chen Ziyang has been carefully observing the direction of the iron chain, which is different from what he imagined before, the pull of the iron chain did not drive the string of coffins behind, and all the coffins were still in place, but with the pull of the iron chain, Chen Ziyang observed that these iron chains seemed to be connected together.

The chains in the entire one-eighth sector were pulled, coming in from one coffin, and out of another hole in the coffin, pulling between the countless coffins. And at the end of the iron chain, one of the iron chains connected to the octagonal coffin has also been pulling, but the octagonal coffin has not changed significantly with the pull of the iron chain.

In general, Chen Ziyang had already understood the routine of the chain movement, but just as he was guessing the effect of the chain pulling his head down, he heard a very crisp clicking sound in the coffin that connected the wheel on the previous floor.

Hearing this crisp sound, the three of them stopped their movements in unison, this sound was obvious, it was the sound of the iron chain pulling to a certain extent, touching some mechanism in the coffin before. All three of them stood there silently, waiting for what would happen next. But the three of them waited for a long time, and the coffins in front of them were still lying there quietly.

"Eryang, what's going on? Why doesn't it move? Shall we continue to pull, or shall we wait a little longer. Yang Lei asked.

Chen Ziyang touched the stubble on his chin, thought for a while, and said, "Let's pull it, maybe it didn't get to the place." Although he said this, he didn't have the bottom in his heart, listening to the crisp sound, it was obvious that a certain mechanism such as a tension spring had been activated, but I don't know why, the coffin in the center still hadn't opened.

This time, because he didn't need to use too much force to pull, Chen Ziyang didn't turn the wheel, he turned to the side, wanting to continue to observe the direction of movement of the chains, Yang Lei and Umbrella Shishuai continued to exert force, and pulled the chains for about a meter. With the pull of the iron chain, all of a sudden, Chen Ziyang saw the coffin lid with more than a dozen coffins suddenly popping out into the air.

The sudden loud sound startled Yang Lei and Umbrella Shishuai, and the two of them quickly stopped what they were doing, shrank their heads and squatted on the ground. Immediately after, in these suddenly opened coffins, countless arrows shot straight into the air.

Seeing the sudden change, Chen Ziyang was also so frightened that he hurriedly squatted on the ground with his head in his hands, and at the same time rolled to the side, hiding in the dead corner of a coffin next to him, and at the same time he was still thinking in his heart, this mechanism is really strange, why do these arrows shoot straight into the air, what is the use of this? Can't hurt anyone, huh? But what happened next made him slap himself in the face in the face.

The top of this stone chamber is all rock, in other words, the whole stone chamber is actually built in a huge crack in the mountain horizontally, and when he first entered this stone chamber, Chen Ziyang had observed the top of the rock three or four meters above the ground in this stone chamber.

He found that the top of the rock was uneven, but he didn't care about it at the time, this was normal, anyway, this rock was used as a roof, and there was no need to repair it so flat, but now Chen Ziyang found the use of these uneven rock tops, it turned out that this rock top was deliberately designed to look like this.

When the arrows shoot straight upward, they hit these uneven rocks, and then these arrows change direction under the action of the rock slope, no longer shooting straight upwards, but change direction, shooting down in all directions, just like a rain of arrows in the sky.

The scene in front of him reminded Chen Ziyang of the kind of weapon that can explode in mid-air that appeared in those gunfight movies, this weapon has many steel needles hidden in it, because it is exploded in mid-air, although these steel needles are fired in a straight line, but if the height is high enough, then the person hiding behind the cover will also have a part of his body exposed within the range of the steel needle, which is simply a 360-degree attack without dead ends.

Although the force of these arrows decreases when they touch the rock, because the distance is relatively close, these arrows still have a strong force after changing direction, and it is not difficult to penetrate the human body. Chen Ziyang, who was hiding behind the coffin, only hugged his head tightly at this time, praying in his heart, hoping that no arrows would be shot at his body.

Although only a few tens of seconds passed between the time the arrow was shot and the time it stopped, these dozens of seconds seemed as long as an hour had passed to Chen Ziyang. When the stone room calmed down, Chen Ziyang felt that his underwear was soaked with sweat.

"Brother-in-law, brother-in-law, how are you?" When the arrow stopped, Chen Ziyang heard Yang Lei's shout from his side, Chen Ziyang was thinking in his heart, strange, who is Yang Lei shouting brother-in-law?

"Dead Leizi, whose brother-in-law are you calling?"

"Wang Ming, he is Wang Lele's younger brother, isn't that your brother-in-law, it's your brother-in-law, that is, my brother-in-law, go and take a look, I heard him shout just now."

"When is this coming, you still have the heart to be poor here." Glancing at Yang Lei, Chen Ziyang hurriedly walked to Wang Ming's side, but he was taken aback at this look, Wang Ming was seriously injured. He planted three arrows, one in his shoulder and two in his left thigh, and all three of them were piercing wounds, which showed the power of these arrows.

The arrow that hit Wang Ming was exactly like the kind of crossbow arrow they had encountered in the passage before, it was the kind of copper pipe arrow, the tail was engraved with the word "Murowei", and the arrow was hollow, but fortunately, these arrows completely penetrated Wang Ming's body and did not play the role of bloodletting, although Wang Ming's expression was very painful, but it seemed that his life should be fine.

After the arrows stopped, Xiao Na and Wang Dawei hurriedly checked the situation of everyone in the team, except for Wang Ming, who was the most seriously injured, only two other team members had abrasions, and Wang Ming was unlucky enough, because the place where he had been hiding before was very empty, and there was nothing that could be used to dodge, so he was hit by three arrows.

At Xiao Na's signal, a pair of officers came over and pulled out the arrows from Wang Ming's body, sprinkled hemostatic powder on the wound, and bandaged him. Every time an arrow was pulled out and every time this white hemostatic powder was sprinkled, Wang Ming would always scream in pain.

But seeing his confident appearance when he screamed, Chen Ziyang also put his heart at ease, her sister was still in a coma in order to save herself, although there is a solution now, but I don't know if I can take the antidote out alive, at this time, this Wang Ming must not have anything to do, otherwise, when Wang Lele is rescued, he doesn't know how to face her.

Just when Xiao Na organized the wounded and prepared to let them leave this stone room temporarily, Xiao Na found that just now, when the arrow mechanism was triggered, in the crack in the mountain where they entered, I don't know when many wrist-thick iron bars had been born, which had sealed their retreat to death.

Looking at these iron bars, Chen Ziyang knew that this was deliberately designed by the people who designed the mechanism, if the people who entered this stone room knew how to open the treasure, then these iron bars would not fall, but if the people who entered here used the wrong method, they would touch these arrow mechanisms, in that case, it would prove that the people who came here were not descendants of the ancient country of Bohai, so it was reasonable to seal them inside.

But Chen Ziyang felt that this kind of mechanism should not be completely sealed, and it should be able to be opened again, because the designer of the mechanism would consider the possibility that it might be a real descendant of the ancient kingdom of Bohai and accidentally make a mistake when opening the mechanism, that is to say, at least he has at least one chance to continue to open these coffin mechanisms, but if they are wrong again, it is very likely that they will be doomed.

Just when Chen Ziyang was thinking carefully about what they were wrong, Umbrella Shishuai came over and told him a very important clue. It turned out that when the arrow mechanism was triggered, although Umbrella Stone Shuai was dodging these arrows like everyone else, his attention was always on the iron chain they had pulled before, and when the arrow was fired, he saw that the iron chain was being pulled upside down.

Before, after the three civil engineers heard a clicking sound, they continued to pull the iron chain, and after pulling about a meter or so, these explanation mechanisms were triggered, but as the arrow was fired, the iron chain was automatically reversing in the opposite direction, and it was also about a meter backwards, and at the same time, the umbrella stone shuai heard the sound of the machine closing, and after that, the arrows stopped shooting.

Listening to Umbrella Shishuai's words, Chen Ziyang suddenly realized, and at the same time gave Umbrella Shishuai a thumbs up in his heart, this is also Umbrella Shishuai, a person who has been a soldier for a long time, can still watch the movements of these organs in such a chaotic scene just now, if you rely on yourself, you may never find the key.

It turns out that their first step is not wrong, but it is wrong in the second step, when the machine is closed, they should not continue to pull the chain, if they continue to pull, then the mechanism inside will be triggered.

However, when the cage was closed, the coffin in the middle was not opened, so that is to say, the mechanism in the first coffin had been used up, and the rest should be the mechanism that pulled the remaining seven coffins. In other words, each mechanism can only be pulled once, so the most important thing is which of the remaining seven mechanisms should be pulled first, and which one should be pulled later.

Thinking of this, Chen Ziyang scratched his head and thought carefully, these eight coffins containing organs are in line with the direction of the gossip, there is no doubt about this, the mechanism that should be opened in the first step is wrong and wrong, and they are confused, but what about the remaining seven? He is not a descendant of the ancient kingdom of Bohai, and he does not know the order of pulling the mechanism.

Chen Ziyang regretted it at this time, why didn't he let these people retreat to the outside of the stone room before he was completely sure of pulling the mechanism, in that case, at least they now have someone to answer outside, and now all the people are trapped here, which is not easy to do.

Although Xiao Na was now leading a few people to study the iron bars that sealed the cracks in the mountain, Chen Ziyang knew that with the equipment they had in their hands, it was really difficult to open these iron bars in a short period of time.

Now the only way is to crack the mechanism in front of him as soon as possible, because Chen Ziyang has a very bad premonition in his heart, if he is the designer of these mechanisms, after the first mechanism is wrong, if the correct order of opening is not followed, then that means that these people in the tomb must not be the descendants of the ancient kingdom of Bohai, they do not know the real order in which the mechanism is opened, then the follow-up mechanism may continue to be activated in a short time.

Although Chen Ziyang has a bit of luck, he thinks that there is a possibility that there is a ** success in ten out of ten should be like this. From the moment he opened the door of this Bohai Palace, he was shocked by the subtlety of the mechanisms in this underground palace, and it was not difficult for the designer of these mechanisms to add a delayed trigger mechanism to these subtle mechanisms, and a sense of urgency permeated his heart.

Now the only clue is the gossip, Chen Ziyang hurriedly touched his body, wanting to take out the compass he was carrying, and use the gossip above to give himself some hints, although he also knew that the tips of the compass might not be of great use, but it was better than looking at the mechanism in front of him here in a daze.

Just when Chen Ziyang was touching the compass in his pocket, he suddenly touched two hard objects, and at this time he suddenly thought that these two things were the two imitation golden gears that Wang Chuan asked Yu Linglong to copy before.

In order to let Chen Ziyang crack the mechanism, Xiao Na handed over the two gears to him, but because it has been useless, Chen Ziyang has forgotten the existence of these two things. At this time, under this mold, he remembered that there were still these two things on his body.

Taking out these two imitation gold gears from his pocket, Chen Ziyang took these two gears in his hand and looked at them carefully, one gear showed the sun-shaped pattern on the front, and the other gear showed a river-like pattern on the back.

After the combination of these two patterns, it was Chen Ziyang who found the dragon hunt for this Bohai Palace, but Chen Ziyang always felt that the usefulness of these two patterns was not only that, he always felt that these patterns had other uses. At this time, because there was no way to crack this mechanism in the dungeon, Chen Ziyang focused his attention on the pattern of these two gears.

After looking at it carefully for a while, Chen Ziyang's eyes lit up, could it be so simple!
