According to the analysis of the current situation, the bones in this trap are likely to be members of the Xiaori army that sneaked into the country back then.

According to Jin Pengfei's recollections, he really didn't hear the old man say that he had seen the army in the surrounding area.

"Could it be that all these well-equipped devils back then were folded in these organs?"

"If that's the case, how big is this cave in the army?"

"Back then, Zhang Ji ambushed 3,000 men and horses here, which was equivalent to an independent regiment. The devil came back then, looking for an opportunity for a sneak attack, and he definitely didn't dare to transfer troops inland with such fanfare, the number of people should not be too much, what do you think, Lao Wei? ”

Lin Yi asked.

Lao Wei listened to everyone's story, and nodded secretly.

Then he said what he thought:

"Advisor Lin, do you still remember that the organ we experienced before was in a state where it had just been activated, can it prove that these people did not come to the position when we came in, and they were all wiped out here."

"It should be like this, these bones in front of them may be the last hope they sent."

Lin Yi said, and suddenly remembered Gong Guisen in his mind.

The location of Zhang Ji's hidden soldier cave, Yu Wenrui knows best, and only by following the line of Yu Wenrui can he finally find the location of the hidden soldier cave.

Therefore, the real purpose of his research on Yu Wenrui and Zhang Ji was to find this special force that secretly infiltrated Ganlong back then.

Thinking of this, his mind suddenly brightened.

The fragmented information before seems to have found the main line all of a sudden, and as soon as the things in the outline appeared, all the information was strung together.

Zhang Ji dug this Tibetan soldier cave back then to deal with Lu Shuihu and quell the border rebellion.

After Yu Wenrui came here, he found the location of this hidden soldier cave, so he took the initiative to apply to stay away from the political core of the Ganlong region, and lived on the edge of the desert with a wise attitude of self-preservation.

In the image of a "crazy inventor", in this underground fortification, he carried out his own various experiments, as for his ultimate goal is unknown, but the result must not be as expected, otherwise history will definitely remember him as the number one person.

This fortification was later found by Xiao Ri's troops, who wanted to take a shortcut and infiltrate the territory with one hand to "secretly Chen Cang", but they did not expect that this hidden soldier cave was full of dangers, resulting in their total annihilation, and even their headquarters did not know their final destination.

Gong Guisen tried his best to hide his name and infiltrate the Great Northwest in order to find the whereabouts of this secret force back then.

So, after so many years, what is the purpose of Xiao Ri not forgetting to find the whereabouts of this army?

To find the answer to this question, you have to go deeper and deeper into the heart of the underground fortifications.

"Officer Jin, how are you resting?"

"No problem, it's nothing."

Jin Pengfei thumped his chest.

"Alright, pack your things, and let's move on."

The group returned from this passage and walked into the passage that Wang Qiang was looking for again.

After walking a few steps, I saw a raised brick at the lampstand on the wall.

Jin Pengfei clearly remembered that when he rushed in recklessly just now, he didn't see this thing.

That's why he rushed in regardless of it, triggering the mechanism and almost affecting everyone.

Fortunately, it didn't cause a big disaster, and now that I think about it, I really want to smoke myself dozens of mouths.

At this moment, he is even more impressed by Wang Qiang's judgment.

Lin Yi touched the bulge with the vajra umbrella, and two iron plates stretched out from the ground again, covering the area they were about to step into, ensuring that they would not trigger the trap.

It seems that as long as you can find these protrusions in the lampstand on the wall, you will be able to find the right path without any problems.

The speed of the group has also increased a lot.

In the winding road, it took about ten minutes to walk, and a total of four triggers were calmed down.

Judging by the stride of adults, they traveled about a thousand meters, that is, these mechanisms appeared every two hundred meters.

After summing up the experience, everyone's hearts that have been hanging all the way can finally be let go.

You can also chat with each other and relax on the way.

Just as they had lifted the previous mechanism, and before they had taken two steps, the green bricks under Lin Yi's feet suddenly showed signs of loosening.

"No, get out!"

Lin Yi realized that something was wrong, and hurriedly shouted for everyone to evacuate this dangerous area.

Unexpectedly, on the way here, an iron fence suddenly fell from the sky and smashed heavily on the ground, completely sealing their retreat.

"Lao Lin, the back is blocked!"

After the break, Wang Qiang shouted.

At the moment when Lin Yi turned around, another iron fence descended behind him, stirring up countless dust.

Two iron fences, one end at the other, trapped them completely.

"What the is going on?"

Wang Qiang pulled the railing of the fence hard.

The iron-cast fence does not move at all.

The heavy edges at the bottom were four fingers thick, and the weight dropped to smash the bricks on the ground into pieces.

"No, according to the distance we just estimated, how can another trap suddenly appear after passing through it? And this trap doesn't have any marker warnings. ”

Everyone is trapped in an iron cage, and now they are called every day and the earth are not spiritual, and they are completely in a state of passive beating.

The one who reacted most violently was Wang Qiang.

This path was chosen by him, and for this reason, he had a little unpleasant trouble with Jin Pengfei, and almost took his life.

I didn't expect this kind of problem to occur after just walking for more than ten minutes, isn't this equivalent to slapping him in the face?

"My hexagram won't be wrong, it will definitely not be wrong, there must be something wrong with this organ, it must be a ghost made by a little devil on a dog day, and it won't stop when it's dead!"

Wang Qiang scolded, raised his feet and kicked the iron fence a few times.

"Brother Qiang, don't be impulsive, don't be impulsive, let's think of a way, we will definitely be able to get out."

Qian Sheng immediately comforted.

Lin Yi is the backbone of their side, and they must stay calm at this time.

His gaze remained on the cast-iron fence in front of him.

"Do you see what's wrong?"

Lao Wei came up and asked.

He is worthy of being an old policeman, he is not in a hurry when encountering problems, and he gives people a very down-to-earth feeling.

The trap has so far fallen two fences, and there is no further action, and everyone's emotions have gradually calmed down.

"The cast iron used in these fences is not the same era as the iron plates we have encountered before."

When Wang Qiang heard this, his eyes widened.

A few steps rushed to Lin Yi.

"What am I talking about, it must be this little devil who kills a thousand knives to make a ghost, these bastards can't die well."

"Stop!"

Lin Yi made a "T" gesture.

"The casting process of this iron fence has not yet advanced to that point, and the process it uses is called 'steel filling method', which originated in the Northern and Southern Dynasties period, and is ahead of the casting process of laying subway slabs before, and it is only at the level of more than 100 years."
