Li Xun continued to walk in front.

"Brother Xun, it's a big commotion. ”

After walking for another ten minutes, about a few hundred meters away, Lao Niu's instrument showed that when he was now three hundred meters underground, Xiaobao suddenly said a word.

Li Xun nodded, licked his lips and said, "As soon as the hole is opened, I can smell it." This is the hole that the serpent crawled out of and crawled into. The further inside, the stronger the smell. The further it went, the newer the smell became, indicating that it had been here not long ago. It's just that I still don't understand a question. ”

Xiaobao said: "Is that the question is, it has all entered the hole, how did it build the stone slab from above, and then cover the soil on the stone slab?"

Li Xun nodded: "Yes, it's this puzzle, it's hard for me to die, it should be someone from Xujiashan Village who helped it get it, but it's not right." ”

"What's wrong?" At this time, Expert Xu took two steps closer and interjected.

Li Xun thought for a while and said in a deep voice: "I can feel from the words and deeds of those villagers in Xujiashan Village, they should not have seen the true appearance of the big snake. They had only heard of it, or had seen it indirectly, but they had never seen it with their own eyes or had come into close contact with it. ”

"Why?"

Li Xun said: "Feeling. ”

"Do you feel right?"

Li Xun smiled: "Normally, no. ”

“……”

After walking one hundred and eighty steps forward, Li Xun stopped, and a large group of people behind him also stopped.

Everyone looked at each other and was silent.

This straight cave finally came to an end, and a fork in the road appeared in front of it.

A cave is divided into two caves, and sure enough, it is the detector of the old cow, and the cave below is a set of one, which is simply ******.

Li Xun said: "Go to the left or go to the right?"

The old cow asked the warrior to carry the instrument on his back, and after opening it, he said, "I'll probe it first." ”

The sound of the radar rang out, and everyone held their breath.

After a while, Lao Niu turned off the instrument with an expressionless face, handed it to the logistics soldiers, looked at the people who were looking at him, and said, "What do you see me doing?"

Lao Xu said: "What are you talking about? ”

Lao Niu smiled bitterly: "The clear way of fart, there is no result at all." There are many caves down there like cobwebs, don't ask me, I just look at the instrument and talk. Now that the instrument is not working, I can't help it. ”

As he spoke, Lao Niu sighed again: "Li Xun, don't you know how to smell it?" It's so stupid, don't you smell it on any side of the road." ”

Li Xun spread his hands: "I've already smelled it, otherwise I wouldn't have asked you which way to go." Now, the road on the left, and the road on the right, smell of it. The intervals between the crawls were not too long, and I couldn't tell where it was thicker and where it was lighter. ”

"Both?"

The crowd exclaimed.

The old cow said, "That means, both roads are fine?"

Li Xun nodded: "Yes, try your luck, it may be possible to do both, it may be only one, which one do you say? Don't ask me, I don't feel sure." ”

Everyone stood at this fork in the road in embarrassment and discussed, at this time, Lao Xu said: "That can only block luck, five or five." I'm rock-paper-scissors with you, I won, go left. You win, go to the right. ”

Li Xun nodded: "This method is good." ”

Immediately, he and Lao Xu rock-paper-scissors made a final decision. Lao Xu won, and immediately said, "Then go to the left." ”

Li Xun took the lead in stepping into the fork in the road on the left, but found that the cave on the left was still all the way down. Now it's 400 meters underground, and it's all the way down, and God knows how deep it is.

And the strange thing is that these two roads still have stone steps. This is a bit strange, could it be that the two roads end up in the same direction?

The crowd continued downward.

After walking for about ten minutes, Li Xun suddenly stopped.

Captain Zhang followed closely, but he didn't expect Li Xun to stop suddenly, almost hit his head, and wondered, "What's wrong with you?"

Li Xun didn't speak, but his body suddenly began to sway, his face turned pale, and he didn't gasp, as if he was holding his breath very hard.

Everyone was shocked, Li Xun should be guilty of some acute illness, right? How is this good, Li Xun is simply the soul of this team, if something goes wrong, who will dare to lead the way and continue to go down.

"Li Xun, what's wrong with you?"

"What's wrong with you, Li Xun?"

“……”

The crowd gathered around and asked with concern.

Xiaobao hurriedly shouted: "Gas mask, quick, is there a gas mask?"

Gas mask?

Everyone was shocked, is there a poisonous gas here?

Seeing that everyone was still stunned, Xiao Bao screamed anxiously: "What are you, gas masks, I asked you if you have gas masks." ”

A soldier hastily took out his backpack: "Yes, yes, yes." ”

As he spoke, he took out his gas mask and ran forward, and hurriedly brought it to Li Xun.

After being strict, Li Xun's face gradually returned to ruddy, and his breath stabilized.

After a few moments, he took a deep breath and came to his senses, but there was an uncomfortable expression on his face.

Lao Xu asked worriedly: "Li Xun, what's wrong with you?" No problem, why don't we go back the same way first?"

Li Xun waved his hand weakly and did not speak.

Xiaobao said, "Are you stupid? Don't you smell a strange smell at this time?"

Not to mention that I haven't paid attention to it, everyone was collectively shocked when I said it.

sniffling, and sure enough, there was a very fishy and stinking smell in the air, which was a little choking.

I didn't notice it at first, because it was a process of gradual increase in smell. After getting out of the hole, there is a faint fishy smell. After walking through the hole on the left, there was a foul smell among the fishy ones, and the further you went inside, the stronger the smell became.

Because it wasn't a sudden smell, I walked slowly, and slowly got used to it, ignoring the smell.

At this time, after Xiaobao's reminder, everyone suddenly felt that the smell here was really disgusting. It's indescribable, it's a mixture of fishy and stinky, worse than.

The old cow was stunned and said, "Is it poisonous?"

Xiaobao said: "It's not poisonous, it's just stinky, Brother Xun is stunned." ”

"Huh?"

Stinky and dizzy?

Everyone was a little confused.

But Lao Xu vaguely knew the reason.

Li Xun's special thing is that his nose is a hundred times stronger than that of a normal human, and he can judge the scene as if it were seen by the eyes through the extremely subtle odor molecules in the air. This is an infinite amplification of the smell.

He can smell what others can't, and at the same time, he ...... Once the pungent smell appears, he will feel it more intensely than others.

The stench of this place made them all a little disgusting and choked. What's more, Li Xun, who is super sensitive to smells?

Between breathing and breathing, almost all of them endure with super willpower.

If he endures it to the limit, he can't bear it anymore. Li Xun is also a human being, in such an extremely foul-smelling environment, he soon fainted due to lack of oxygen to his brain. If he didn't rely on a gas mask to isolate his breath, Li Xun would probably be carried out.

Yes, Li Xun didn't expect it to be so stinky here. The disadvantage lies in not preparing in advance.
