Chapter 260 The Realm of Countercurrent
After Xian Hongye stared at the ground full of feces and bones on the other side of the river for a while, she suddenly understood the reason.

She told us both: "What Lao Tian smelled was not poisonous gas, but ammonia gas. You can't go to the other side of the river, or you will die."

It turned out that because of the large number of bats at the top of the cave, tens of thousands of tons of bat guano had accumulated on the side of the cave. These things, together with the dead bodies on the ground, would be like a huge biogas pool, releasing a large amount of bat guano. Ammonia and methane, and as the concentration continues to accumulate, those toxic gases can already reach the level of killing people.

In terms of danger, those bat guano are worse than centipedes.

As for why there is no stench in the underground river and the other side of the underground river, according to Xian Hongye's thinking, it is probably related to the extremely special air circulation system of this cave.

Similar to what I guessed when I came in, Xian Hongye also believes that there is an advanced and complex air convection system in this cave, which is related to nature and the excavation factors that I think.

Because of the existence of this "system", the air will be extremely dry when we first enter the well. The existence of this system also makes two opposite air convection environments formed on both sides of our body. The river serves as a "neutralization point" so that the humid air on one side cannot cross the other bank of the river, and the poisonous gas on the other side of the water cannot cross the water surface.

It is probably also because of this special set of air illusions that the centipedes and bats on one side formed a clear division pattern, thus sandwiching us in the middle of the river.

...After Xian Hongye finished speaking, I understood everyone's situation, but the following questions were no less than before.

You know, it is impossible to go to the other side, because we only took three gas masks when we came down. When we met the centipede just now, the one of Xian Hongye was kicked away by me along with her backpack, and the rest were also gone. It may not necessarily support our survival in high concentrations of poisonous gas.

And it is impossible to go back to the other side of the river. I know that even if those centipedes have dispersed now, as soon as our feet step on the river, those harmful things will definitely come running along the bloody smell on us, continue Harm.

In this way, the three of us tacitly understood that there was only one possibility left.

Take the water!Follow the stream all the way up.

This is indeed the only way to go right now, because if the "thing" that robbed Lin Shaosong and Batulu is really some kind of large creature, it is likely to have only this way to go. This dog's discovery, It also indirectly proves this possibility.

So, without talking too much, I took out a bundle of climbing ropes, locked the backpacks and belts together with buckles, and then everyone supported each other and went upstream to the farther source of the water.

Along the way, we slowly realized the coldness and danger of this underground water flow. As the four of us gradually deepened, the water, although the deepest and at most below the ankles, became more and more cold, and as the flow increased, It takes away body heat more quickly, and after only ten minutes, I can't even feel the existence of my toes.

But even so, we can only grit our teeth and move on, because Batulu's life and death are unknown now. I want to save him, and I want to save everyone.

During the persistence, Xian Hongye tightly grasped the skirts of me and Wang Hou, her face was also extremely ugly, her purple lips were also "talking" to us, and the heat in her body was also rapidly losing.

Xian Hongye's sensitive hands seemed to be able to feel the trembling of Wang Hou and me in the cold water, so she said to me and Wang Hou with some self-reproach: "Everyone is shaking so much, because of me, you two are in trouble again. .”

I shook my head slightly and said, "Your business is our business! And..."

I didn't continue my words, because I wanted to ask Wang Hou if Xian Hongye had feelings for him.

But in the end, I didn't say it. First, the environment is not suitable. Second, I feel that this question is meaningless.

I can feel that Xian Hongye, like her father, is a businessman in her bones. Such a woman is very smart and capable, but she is definitely not a housekeeper.And after getting in touch with Xian Yuhe and Yahai Nanzi, I suddenly discovered that their rich people's social circle and emotional world are too complicated, so complicated that ordinary people like me daunt them.

In Xian Hongye's heart, there is something that makes me feel uneasy and afraid. This kind of thing is called "class".

Also because of the existence of these two words, I feel that matching Wang Hou and Xian Hongye is a very thankless move, and... it doesn't make any sense.

Besides, although Lin Shaosong was unbearable, he could throw [-] euros for Xian Hongye, but what could Wang Hou do for Xian Hongye?Do you have nothing to do and beat people every day?
With these miscellaneous thoughts, I don't want to say anything more, Wang Hou seems to be more sensible, he shook his head slightly, said a word to go quickly, and then stopped talking.

I looked at Wang Hou's dignified face, and suddenly felt that this guy seemed to be absent-minded. He was thinking about some problems that I couldn't understand just like when he first came out...

What's wrong with this kid?
In this way, the three of us flowed upstream in the freezing water stream for half a day, and finally came to the end of this series of streams!
That... is an underground waterfall.

This small underground waterfall has a very high drop. We used a flashlight to take photos, but we couldn't see the top of the waterfall at all. If we only make a rough estimate, it would be more than ten meters.

The waterfall falls almost vertically along the stone wall, forming a pool of one square meter square. Behind it is a huge high wall of a karst cave, which is covered with bat guano and strange-shaped stalactites. Any steps or hanging ladders that can be climbed are seen on the stone wall.

For a while, we were in a desperate situation again.

Facing one after another of difficulties, everyone was inevitably a little discouraged. Wang Hou even threw the dead-faced Agou into the water, shook his head while wiping his sweat, and said, "Deadly...what should I do? There is no way."

Compared to Wang Hou's anxiety and my discouragement, Xian Hongye was much more careful. She didn't say anything, but picked up the flashlight and carefully observed the structure of the small waterfall and the rock wall of the cave, as if she was unwilling to give up the little hope she had.

Xian Hongye's attitude of giving up is good, but I think this kind of search for a needle in a haystack should be useless, and even if there is an entrance, I think the most likely place is not the stone wall, but the underground waterfall formed by the perennial impact. small pool.

etc!Puddle!
