Faced with the mechanism accidentally discovered by Wang Yining, everyone studied it.

Yue Xiang didn't understand this kind of thing at all, but he could also tell that there seemed to be some kind of hidden track under the floor tiles manipulating the entire structure. Perhaps, according to some law, these floor tiles hidden under the soil layer are rearranged and combined, and the truth will appear. But he wondered if there really was such a sophisticated mechanism in these days? Is it possible? Could it be some kind of trap or something? Wouldn't it be more convenient to simply use brute force to pry these bricks up and see what is hidden underneath.

But his idea was first rejected by everyone, Yue Xiang had no idea, Ma Li and Wang Yi would rather be old fritters who have been in the rivers and lakes for a long time, well-informed, and know that organs of this scale generally have a three-ring ambush, specializing in brute force destruction, and the dark crossbow flip board poison falling stones and the like are impossible to prevent, especially in this narrow and closed environment, chaos is equivalent to looking for death.

Moreover, after careful study, Ma Sandao and Li Shoucai actually saw the doorway.

These words are not indiscriminately engraved. It is a scripture, a scripture in the five parts of Hongyang Linfan Piaogao. Li Shoucai carefully discerned while chanting, "That's right, I remembered, this is the Mixed Yuan Hongyang Explicit Result Sutra in the Five Books, it should be like this, Yongxin always recognizes his hometown, and always has confidence to open his mind." There are no four phases, no old and young, and the hometown of Bliss recognizes peace and ......"

Li Shoucai shook his head and chanted the scriptures, Yue Xiang wanted to laugh when he heard it, this is also a scripture, this half-text is like a limerick, no wonder it can also deceive the ignorant people.

"So it's just a matter of moving these bricks and slabs back to the original order of the scriptures?"

"That's how it should ......"

Ma Sandao and Li Shoucai responded with their mouths, just looking down, and their attention was completely focused on the ground. Although I know how to crack the mechanism, but it is still not easy to recover, this is like a Rubik's Cube, you have to have a special brain, especially good at analysis and calculation to get it, if you try step by step, then I don't know when to get it.

"It should be a piece first, anyway, let's try it......" After watching for a long time, Ma Sandao finally squatted down and started to act. Because there is only one vacancy, the first step is either to move the left vacant seat or to move the right one, he grabbed the right tile crack and moved it hard, and then he heard the sound of a mechanism rubbing, the original vacant seat was filled, but a new vacant seat appeared.

"That's right, that's it, just restore the original order."

The words of excitement sounded, and for good reason. But before the people present could come to their senses, a change suddenly occurred. At the entrance of the chamber, an iron fence suddenly rose from the ground without warning, sealing the exit of the chamber immediately. Yue Xiang was startled, and subconsciously hid to the side, but when he looked back, there was no movement.

"W-what's going on?"

Rao is a bold person, and there is no one who does not panic at this time. Ma Sandao and Li Shoucai were also dumbfounded, thinking that they had touched some mechanism by mistake, and retracted their hands as if they had been electrocuted. Yue Xiang and the others reacted, and immediately stepped forward to grab the iron railing and shook it violently, but the iron prison door did not move at all, and no matter how strong the manpower was, it was difficult to defeat the power of machinery after all.

"It's got to be triggered, we're stuck here."

The situation in the secret room is no different from that of a prison, with lifeless empty walls and iron-barred doors. A group of people shouted inside, and Yue Xiang pulled out the sword he carried with him and slashed towards the iron gate. But the iron railing was as thick as an egg, and the sparks sparked on it, but the effect was not good. If it is chopped hard, I am afraid that if I cut one of them, the sword will also be scrapped. Moreover, depending on the tightness of the iron bars, cutting an uncreated gap may not allow people to get out.

"What the hell are you two doing!?" The others didn't move, and the suspects were naturally only those two. Ma Sandao and Li Shoucai were also inexplicable, and in the face of Yue Xiang's fierce questioning, the two waved their hands again and again to defend themselves.

"We just moved a brick......"

"! You two idiots must have gotten this mechanism out of the wrong order, get it back for me! Yue Xiang scolded, and the two hurriedly returned the floor tiles that had just been moved to their original positions, but the iron door still did not move.

"Why didn't you respond!?" Yue Xiang was really a little anxious, it seemed that he still underestimated this ancient mechanism technology, he really didn't expect this technology to be so advanced. Just now, I really should have left one person outside to control the wind, but now it's okay, give a spoonful of stew, and it's all blocked in here.

"Don't shout!" At this time, Wang Yining on the side suddenly spoke. "I think the mechanism of this iron gate is probably designed a long time ago, no matter how those floor tiles move, as long as they are touched at the beginning, they will definitely be triggered. If you think about it, if you don't, how can you guarantee that the secrets of this place will not be leaked? Isolate this place, and the people locked in it can only find a way out if they concentrate on cracking the mechanism. ”

"What? So this mechanism is deliberately set up like this? ”

"That's right, as long as this mechanism is triggered, whether you want it or not, there is only one way to crack the floor tiles. If you can find a way out, you will get out of trouble. I couldn't find it, so I naturally had to be trapped in it, and I wasn't afraid of leaking out of this secret. ”

"Those bones...... Could it be someone who has been trapped here before? ”

"It's possible, but the soil layer on the tiles has not been revealed when these people died, so I don't think it touched the mechanism of the iron gate, and there were no external injuries on the body, so I don't know how they died. There were no corpses in the tunnel outside, all of them were concentrated here, and it was conceivable that these people were also trapped in this secret room before they died, but when we came in, we didn't see the iron gate, which means that the iron gate was not activated. ”

"There are no external injuries, I guess I was poisoned. If the mechanism of this iron gate had been touched earlier, we should have seen the existence of this iron gate when we came in. So we're the first to fall for it. Listening to Wang Yining's analysis, Yue Xiang quickly calmed down, but he still had doubts.

"But there are still flaws in this, and although this iron gate is strong, it is not indestructible, and as long as the person who comes has enough tools, and there is someone outside who responds, it can still be opened. It's just that there are fewer people to make a difference. ”

"Let's not talk about the remoteness and seclusion of this place, the mountain roads are rugged and difficult to walk, whether the brigade of people can pull it up. Even if you just said it is complete, I'm afraid that this tunnel is not so simple. You can think that the people who cultivated this secret path at the beginning can naturally imagine it, and if you can't say it, there will be an ambush on the next level. ”

"What's the ambush?"

"I don't know, but it doesn't seem like it's a dead end." At this time, it really shows the importance of Wang Yining, a dog-headed military advisor, and the analysis is reasonable and well-founded. Yue Xiang thought about it for a while, and decided to follow Wang Yining's advice to seize the time to crack the order of the floor tiles and see if he could spell a way.

The four men squatted on the ground and gathered together, and Ma Sandao memorized the scriptures completely, and Wang Yining rolled his eyes to calculate the order of movement compared to the position of the floor tiles on the ground. Yue Xiang really saw the power of this guy's mind, just like the Rubik's Cube master in later generations, he was confident step by step, and even if he made a mistake, he could quickly correct it.

This guy seems to be good at finding implicit patterns and clues in a mess of conditions, but ......

Yue Xiang looked at Wang Yining, his eyes were also rolling as a thief, and he didn't know what he was thinking. Wang Yining noticed this and said dissatisfiedly: "I said what are you peeping at there, and you don't dare to come over to help?" You...... Well? As he spoke, he was about to stand up, when he suddenly swayed involuntarily, almost fell, and barely stood firm by holding on to the wall.

"Head...... Dizzy? ”

Yue Xiang thought that he had been squatting on the ground for a long time, but his mind suddenly felt dizzy for no reason. He sat directly on the ground with a shake of his body, his whole body was sore, and he couldn't even hold the knife. Looking at Ma Sandao and Li Shoucai both falling to the ground, the four men all looked the same, and they all fell to the ground in less than five seconds.

Only Xiao Wan is left, and she is fine.

Poisoned! When this word flashed in Yue Xiang's mind, his whole body was already sore and weak, and he couldn't exert half of his strength. He struggled to squirm on the ground, but fortunately he still had the strength to move his tongue.

"Ah, little ...... ......"

Xiao Wan is a female streamer, she doesn't know the scriptures of Hongyang Sect, she has no strength, and she doesn't have the same mind as Wang Yining. Just now, just to try not to get in the way, I stood aside and didn't say anything. As a result, she saw that the four men, including her husband, suddenly fell to the ground, and she was immediately stupid, and she couldn't even speak with her mouth wide open. Hearing Yue Xiang call her like a **, she reacted, and ran to Yue Xiang's side quickly, her voice was already crying, but she couldn't understand what she was saying.

"Don't ...... Don't cry...... you...... Why are you okay......" When did Yue Xiang fall into such a dilemma, he was helped up by Xiao Wan, and saw that Xiao Wan's face was not abnormal, so he asked weakly.

"Concubine...... I don't know, what's wrong? What happened to you, Xianggong? Xiao Wan burst into tears at the moment, holding Yue Xiang's body and shaking. The rest of the people tried to turn the angle of their necks, and when they saw that Xiao Wan was fine, they all showed incredible expressions on their faces.

"We ...... We've probably all been poisoned, and this room ...... It may be poisonous, and our whole body is sore and weak now...... Are you okay? Yue Xiang tried to gather a little strength, but his hands and feet felt like squatting or sitting for a long time, and the only thing that was better was that he could still speak.

"Poisoned? Concubine...... Why didn't the concubine feel it? Xiao Wan cried, not knowing what to do.

Over there, Wang Yining's body arched one after another, like a worm wriggling on the ground, and finally arched to a corner. said loudly: "Brother and sister, you ...... Didn't you get poisoned? ”

"She didn't...... Poisoning! Yue Xiang took her to answer.

"This house...... There must be poisonous gas inside, did we inadvertently touch the mechanism just now? Wang Yining was puzzled, but he didn't know what he was wrong just now, even if he touched the mechanism, there had to be a sound, such a silence, Bengen couldn't prevent it.

"Organ...... No, it's not a mechanism, I know, it's those oil lamps, those oil lamps have a problem! Yue Xiang's mind suddenly flashed with that strange miserable blue flame and black smoke, and he suddenly realized. The oil is poisonous in it, and when it burns, it turns into poisonous gas and gathers below, and our tunnel extends diagonally downward, and the poisonous gas naturally gathers in this secret room. After a long time, the house is full of natural gatherings. This poisonous gas is colorless and tasteless, and only if you don't get hit, there will be ghosts. ”

"That'...... Why is Xiaowan okay? ”

"Nonsense...... Since this mechanism is all made by Gao Huai, it is natural that one day he will have to wait for Xiao Wan to come to retrieve the treasure. Maybe it's already pre-arranged. ”

Yue Xiang has now understood Jiucheng, since Gao Huai told Xiaowan the secret words of the incense burner mountain, he expects her to come to retrieve the treasure one day. Since there is a poisonous gas mechanism here, it makes sense to take some defensive measures on her early, such as cultivating an antibody or something.

And like today's situation, if a few of them are replaced by people who hold Xiao Wan hostage, they will eventually be put down by the poison gas unknowingly, and only Xiao Wan can get out alive. It can be seen that Gao Huai took great pains to build this secret passage when he first built it, and considering various circumstances, he thought that the mechanism of this iron gate might also have a way to restore it.

"Xianggong, concubine...... I really don't know what's going on......" Xiao Wan heard Yue Xiang's tone seem to be a little wrong, and her face suddenly turned white in a hurry.

"I know...... Don't cry! Hurry up and put out the oil lamps in this house! ”

"Can't be destroyed!" Wang Yining shouted, "If it's extinguished, you won't be able to see anything, and besides, there are also outside, not bad for these four, this oil lamp can illuminate, even if it is poisonous, let it be lit, this is the only hope for us to go out!" ”

"Then what do you say now?" The latter sentence Yue Xiang shouted at Wang Yining.

Wang Yining obviously also figured out the meaning of Yue Xiang's words just now, thought for a while and said, "I don't know if this poisonous gas is deadly, it's absolutely not okay to wait here." The back road has been cut off, and there is only a way out if we quickly untie this mechanism. Xiaowan, you help me up against the wall, I will command, you will move the floor tiles, do what I say. ”

It took Xiao Wan a lot of effort to drag the four of them to the corner of the wall. Then follow Wang Yining's instructions and start moving the floor tiles. Yue Xiang leaned against the wall, gradually feeling a little groggy and delirious, and it was difficult to concentrate. Even Wang Yining's voice, which sounded in his ears, became distorted, and his saliva flowed out of the corners of his mouth, wetting a large piece of his clothes.

Time passed silently, but Yue Xiang was already difficult to feel, he only felt that there was a hazy chaos on the sensory level.

I don't know how long it took, but I heard a click. Yue Xiang's spirit seemed to have been pricked by a needle, and he was a little more perked. He opened his eyes as if he were demented, and rolled his eyes blankly. But I saw Xiao Wan tired and sweaty, standing there staring at the ground, feeling a series of mechanical sounds under the floor. Looking at the floor tile puzzle on the ground, it has been completely restored, and the only vacant space is actually in the position that I first saw.

"Spell ...... It's over......" Xiao Wan was so tired and out of breath that she couldn't stand anymore.

"This ...... Why is this not happening? Wang Yining's anxious voice echoed in the space, and the sound of mechanical operation had stopped, but no secret door was opened.

It's over...... This was the only thought that came to Yue Xiang's mind.

"Wait...... What is this? Suddenly, Xiao Wan stared at the empty seat and exclaimed, only to see that the situation inside was different from what she saw at first, and a concave shape appeared in the empty seat at some point, and the shape looked very familiar.

"This is ......" Xiao Wan hesitated to look at the concave, then took off the strange-shaped jade pendant hanging from her waist, and gently placed it in the concave, it was as tightly as if it was made in heaven and earth.

Suddenly, Yue Xiang seemed to feel a strange wave rippling his nerves, like a stone thrown into the water and causing a ripple. A burst of white light flashed before his eyes, and then he fell backwards as the wall he leaned against suddenly sank backwards, silently cracking open.

With Xiao Wan's exclamation, he fell defenselessly into the hole behind him......
