"This kind of mechanism is generally defenseless, silent, and more concealed than other agencies, but once discovered, it is easier to deal with than other agencies."

"You only need to expel the gas for a while, and use this time to break through the area covered by the poison gas."

"It's just that there are two more problems, we don't know if this covers other organs, and we don't know what the specific scope of the organs is."

"With a mechanism like this, it's possible to place multiple trigger points, and in a short tomb, there's basically no way around all of them."

"But what is sober is that the gas chamber that needs to store poison gas under this is not small, presumably even if there are other organs that cover, due to the space of the organs, it has seriously affected the area that can be covered by the organs."

"Presumably, the area we are in is not going to be a place to cover the authorities."

"In this way, we can use the same trick used by the leader of the second group to throw stones to ask for directions, but the speed must be fast."

Hidden Dragon stared at the tomb in front of him, and breathed a sigh of relief, although it was still a little troublesome, but there was already a solution, and everything was easy to do.

"Is it really that easy?" I feel a little uneasy in my heart, although Hidden Dragon is a master of this mechanism, but I always feel that the mechanism of the tomb path is not so simple.

The spike traps that almost kill the first group seem to be ordinary traps, but in fact, the trigger range of the traps is very wide, and the place where they are placed is also extremely clever, completely activating the dead end, and at the same time, it also chooses a place that is most likely to be careless.

This time, all the people Qian Lao went to the tomb to find were insiders, and there was no layman, even if he was not a master of a hundred battles, he was also a person who had several inverted fighting experiences, but no one found that something was wrong, which is already very revealing.

Although the tomb has been delayed here for a long time, and even the Hidden Dragon didn't find anything at first, I still feel that it is a little too light.

"Ready, throw all the hiking bags in, and pick them up by the way after passing the hiking bags."

Without waiting for me to say anything, Hidden Dragon lifted his glasses and spoke first, then slammed the hiking bag on his shoulder into the middle of the graveyard.

The others also threw the hiking bag off their shoulders and smashed it into the graveyard.

Click.......

Everyone stared nervously at the atmosphere and didn't dare to take a breath, and there was obviously a sound of the mechanism activating in the tomb!

Seeing that a lot of mountaineering bags smashed into it, some parts of the ground of the cemetery in front of them sank obviously, and everyone knew that the speculation was not wrong.

"Sure enough, there's a covering mechanism! If it's just a poison gas trap, it won't make this sound, there must be a large physical mechanism in it! ”

"Judging by the voice, the orientation of the mechanism after activation is directly in front of it, and the width is about 15 feet, so I can't determine what the specific mechanism is, so I suggest taking two steps back."

Wolong quietly took a step back, and the light in his eyes behind his glasses flashed with thought.

Hearing Hidden Dragon's words, almost everyone simply took two steps back.

Rumble!

Just took two steps back, there was a loud roar, and a large stone door suddenly smashed down in front of the tomb, blocking the road ahead.

"Take the bag and get back!" Hidden Dragon's pupils shrank suddenly, grabbed the bag closest to him, turned and ran wildly behind.

I'm not standing in the front position, but it's better to react quickly, and I can be considered to be the first to withdraw.

As I was leaving, I faintly heard the sound of gas being released, presumably the gas mechanism had been activated.

Now that one side has been blocked, the poison gas will only go in one direction, and they can only run in one direction, if it is a little later, who knows how quickly the poison gas in it can be deadly?

But fortunately, everyone reacted relatively quickly, only two or three did not take their bags, and everyone withdrew safely.

I don't know how far I ran, almost all of them didn't look back, they just ran forward, don't look down on Qian Lao, he is older, but he runs quite fast, and he is even at the front of the whole team.

It wasn't until they couldn't see the part of the tomb road they were in before that everyone rested for a while.

"It seems that the mechanism of this cemetery is really not simple." Qian Lao slowed down for a moment and sighed faintly.

"Now the road to progress has been blocked, and it is still filled with poison gas, which is most likely mercury vapor, which is inert and very difficult to move and dissipate, according to the poison gas commonly used in the graveyards in the past."

"If the mechanism that opens the way forward is still in that position, it will be quite troublesome, the high-purity mercury vapor is very fast, and the most mouth protector here is an industrial-grade dust mask, which can't block the mercury vapor at all."

Hidden Dragon's gaze was also quite solemn, and he said with a wry smile.

Hearing the words of these two, my heart sank suddenly, could it be that this time I can only stop at the tomb?

"There's no other way to get through? Do you think there will be other passages? "I was a little reluctant to speak, in fact, I could see that everyone present had some unwillingness in their eyes.

Especially Qian Lao, I can vaguely see Qian Lao's dry hand tightly clenched into a fist.

"Tang Li, you have observed the most carefully, have you noticed anything wrong when you came over, and there may be a place where there is a mechanism?"

Qian Lao thought for a moment, stared at the white begonia pear on the side, and spoke.

Bai Tangli's white-looking hand shook slightly, slowly touched his head, and said:

"Let me sort out what I see in my head, maybe there will be some clues."

Immediately, Bai Tangli was silent, obviously in a state of thought.

Everyone didn't make a sound at all, and they didn't dare to gasp for a while, but their eyes fell on Bai Tangli's body.

Memories kept flashing in Bai Tangli's mind, and the tombs between each other overlapped, dismantled, overlapped, and repeatedly identified in his mind.

At this time, Baitang Pear's brain is like a supercomputer, quickly distinguishing all these things that are wrong.

It wasn't until a moment later that Bai Tangli raised his head, and an inexplicable look flashed on his face.

"There are really two things that are not right, but I'm not sure, and I need to walk back along this tomb road to have a look."

"As for whether or not it can lead to the mechanism in the back, I don't know yet."

Everything can only be left to fate, I smiled bitterly, thinking that this Baitang pear can find the mechanism leading to the back.
