Li Mowu's stomach still looked a little bulging, I don't know if there are any of these things in it, Qiu Yan feels that it is better to let him vomit it all if it is safe. So he helped Li Mowu up, grabbed his throat, and made him continue to vomit, but what he vomited out next was pale green bitter water, and finally it became retching.

Qiu Yan believes that it should be gone, and if there is more, it should pass the stomach tract, so it can only be excreted by the body.

The fog has almost dissipated, and the visibility is gradually restored, Qiu Yan continued the work just now, tightened the rattan on his body, and then prepared to put it down slowly, this is very difficult, if he can't catch it a little, Li Mowu can fall directly from the tree, he is now unconscious, and he will not use his muscles and movements to protect himself, then this fall may kill him, so the length of the vine must be controlled.

Qiu Yan prepared everything, and then illuminated the tree with a glow stick, this big tree grows on the edge of the quagmire, and if it is not good, it may fall back into the quagmire directly, and all the previous efforts will be lost, so you must choose a good place.

When the fluorescence shone under the tree, Qiu Yan was stunned for a moment, only to see that the tree was foggy, and he couldn't see the ground clearly. Qiu Yan mistakenly thought that the fog had not dissipated, rubbed his eyes and looked again, it was still gray, and the fluorescence shone past, as if shining on a cloud of chaos.

Qiu Yan didn't deliberately use fluorescence to illuminate just now, and the blurred shadow on the ground could be seen in the afterglow, why can't he see it now? Could it be that the fog is thickening again, but why is it only in the part near the ground?

After careful identification, Qiu Yan found that it turned out that there was no change in this quagmire, and a black gas evaporated from the water, which had enveloped the entire water surface, and the corpses in it loomed, and they seemed to move in the black gas.

The silt at the bottom of the pond was stirred up by something, and it seemed that there was a huge thing moving under the silt, turning up the black gas that existed under the silt. The whole bottom of the pool moved, and there seemed to be an irregular whirlpool in the mud, wrapping the corpses in and spitting them out.

As the silt activity became more intense, more and more black qi turned up from below, Qiu Yan no longer had any extra strength to feel scared at this time, but the gums were tight, and the clockwork on his body had reached the tightest, and it was impossible to go any further.

These black gases can be toxic gases formed by the decay of large amounts of leaves in the swampy rainforest, which is often found beneath silt deep in the swamps and rainforests, and is released if there is a large natural climate change.

Many rainforests are untouchable because the presence of this toxic gas blocks large tracts of pathways. Some poisonous gases are due to the volatilization of special minerals or volcanic gases, or mixed with fog and form highly toxic clouds, the toxicity of this poisonous gas is very good, there are many places in the world that even birds and animals can not pass, such as Bermuda.

It is also unknown if it will cause blinding in the same way as the fog encountered in front of the camp yesterday.

I thought about whether I could go down immediately and rush back to the ruins, but after calculating the distance and time, there was no way at this time, the black gas had already filled under the tree, and Qiu Yan could no longer go down. And if the fog on the other side of the camp does not dissipate, it is likely that you will be poisoned and lose your eyesight, and if you encounter snakes again, there is really nothing you can do.

Qiu Yan prayed, this black gas only spreads under the tree, and will not float up to the canopy, but obviously this is impossible, slowly, Qiu Yan found that the black gas seemed to be alive, rolling and began to fill the entire space.

Qiu Yan knew that if this black gas was poisonous this time, I was afraid that it would be even worse than blinding, so in a hurry, he immediately tore off one of his clothes, smeared a large piece of black mud on his body, covered his mouth and nose, and also made one for Li Mowu. After that, he remembered that he was on a tree, and immediately found a vine to tie himself and hang it on the tree, in case he fell from the tree if he was poisoned and his mind was blurred.

As soon as he finished doing all this, the black qi reached his heel in a blink of an eye, and when it came up, the speed of spreading was amazing, and the black shadow was like a ghost, almost instantly enveloping the branch where Qiu Yan was sitting, and when Qiu Yan even heard it passing, the trees here made a slight crackling sound, and then the places around him were shrouded in black qi as far as the eye could see.

The thin black gas filled the surroundings at once, and looking at the black qi churning, Qiu Yan felt as if he was trapped in a house under fire, but at the same time, he smelled a strange smell, and his throat began to itch a little.

An itchy throat was obviously not a good sign, and Qiu Yan instinctively held her breath and tried to inhale as little as possible.

After a few seconds, Qiu Yan didn't feel any discomfort, and his frowning brows relaxed, obviously this black gas is not very toxic, so it has a great chance of survival, but if you inhale too much, it is difficult to say.

Qiu Yan prayed that the black gas would recede on its own like the mist, and looked up, wanting to see if he could climb higher and reach a place where the black gas was a little thinner, but when he looked up at the entire canopy, he was completely shrouded in these black gases, and under the fluorescent pillar of light, Qiu Yan seemed to see that these black gases seemed to be small particles of solid, which seemed to be smoke, not gas, and subconsciously touched it but couldn't touch it.

What is this? Qiu Yan suddenly felt that he had seen this black smoke somewhere, where was it? Thinking about it, I vaguely felt uneasy in my heart, and an extremely unlucky feeling came out.

Qiu Yan continued to carefully observe the movement of the quagmire, and suddenly, a series of water stirring sounds came from the swamp under his feet, which was very heavy, but not noisy, and sounded as if some behemoth was about to come out of it.

There must be something abnormal under this swamp, otherwise it would be impossible to have such a movement, only to hear the sound of the water getting louder and louder, as if it is getting closer and closer, under the faint fluorescence of Qiu Yan, I saw that in the black air, there seemed to be a black shadow the size of a calf, which was moving with the flow of water, but it was really impossible to judge whether it was a snake or not.
