Toxic gas spring is the product of late volcanic activity.

The main components of the gas emitted from the spring are hydrogen sulfide, carbon dioxide, and carbon monoxide, in addition to a small amount of sulfur dioxide, hydrocarbons, and mercury vapor.

After listening to Chen Lie's exquisiteness, everyone was still afraid.

"Depending on the concentration of the poisonous gas sprayed, the lethality varies greatly."

"Some poisonous gas springs often see poisoned mice and birds. For example, Chiquetang. In 1976, scientists put a strong goose on the poisonous vent of Chiquetang and it was poisoned within five minutes. died."

"And here, the concentration of poison gas is definitely much higher. As for how high it is, I don't have the mind to understand it. I don't mean to be a guest scientific researcher."

Chen Lie left this dangerous place as he spoke.

Looking at the corpses that he could see from time to time, Chen Lie became more and more frightened as he walked.

He is not stupid and bold.

He will also be afraid.

After all, he didn't know when the muddy water nearby would emit a blister, and then explode a lot of poisonous gas.

"I don't know how many ignorant animals have been killed here."

"Only some plants with tenacious vitality or special needs can survive."

Chen Lie jumped over a small valley that was not very deep, pointed at a small animal in the distance, shook his head and said, "Look, that little fox wants to eat the poisoned mouse, but I can foresee its outcome. ."

The poisonous gas here is so powerful that even adults can kill in an instant, the foxes...

Sure enough.

The fox ran over hesitantly, carefully along the way.

But the more careful it is, the slower the speed, the more poisonous gas it will inhale.

Gradually.

Its footsteps began to stagger and its consciousness began to blur.

Not long.

It fell down and couldn't get up again.

Even if it is still a little conscious, the weakness of the whole body makes it only slowly to death when it is conscious.

Then its fresh carcass will attract other animals that cannot find food.

This is the loop here.

So bones are piled up.

"Brother Pet, hurry up and leave, it's so pretty here."

"This is simply the most insidious place in nature."

If nothing works, I persuaded him: "Pet brother, be careful, and pit yourself in."

The queen arrived, Pengcheng Lao Lu and Xiao Lu also followed to persuade.

Interestingly.

When Chen Lie ran out of this dangerous place and saw the familiar and dangerous rain forest, everyone also resumed their active atmosphere.

"After such a big bend, it will take me at least an hour to reach my destination."

"Luckily it's already close."

Chen Lie talked and chatted: "It may be because it is close to the poisonous swamp, so there are so few animals here. Such a lush rain forest, but not many animals, is a bit scary."

"Don't be afraid of pet brother, Xiao Lu chats with you so that you are not afraid."

Pengcheng Xiao Lu replied naively: "Xiao Lu used to be afraid of a person, but if someone speaks, he won't be afraid."

"Thank you, Xiao Lu."

Chen Lie said with a smile.

Although Xiao Lu's IQ is lower than that of ordinary people, even now, it is almost the same as 8 or 9-year-olds, but he has retained enough innocence.

Pengcheng Xiaolu really wanted to chat with Chen Lie, and said, "Pet brother, my father bought me many new pets, including squirrels and hamsters, as well as a little fox and a little mink."

"They are so well-behaved, they are better than the birds I bought before."

"But I haven't forgotten the birds. I feed them three or four times a day."

Xiao Lu seems to like to chat with others.

It's endless when I talk about it.

Chen Lie knew that Xiao Lu lacked close friends, so he didn't mind this attitude, and replied: "Xiao Lu, take good care of your pets. They are your good friends. You can't bully them."

"Little Lu doesn't bully his friends."

Then there was another call.

Don't tell me, when we chat, time flies quickly.

Chen Lie came to the final destination without realizing it.

just……

Chen Lie checked the focus of the map and wondered: "It's not like, there are many rivers on the map that merge into a big lake, but this lake is not big at all."

Chen Lie looked at the map.

The map was provided by officials and elders. The elder's one is very old, but it has been revised many times and is relatively reliable.

The officials relied on the last expedition, modern and combined their own speculations, and finally painted them.

Chen Lie relies on the system to integrate the two maps.

Just according to the comprehensive map information, there should be a huge lake in front of you.

But it was just a bigger lake.

"Is it going in the wrong direction?"

Chen Lie began to suspect that he was lost.

"wrong!"

In the next moment, Chen Lie denied himself: "The lake in front of him is just a small lake formed by the intersection of two rivers, and whether it is on the map of the elders or the map of the officials, there are at least five rivers converging."

"Even if you are dazzled and wrong, it is impossible to make mistakes on such a simple issue."

"That means the place I came to is wrong."

Chen Lie thought for a while, and decisively asked for help from the live broadcast room, and asked: "The great god in the live broadcast room, I don't know who will survey the terrain? I need to find out the terrain and the direction of the water here."

"It turns out that Brother Pet doesn't understand."

"Finally saw Brother Pet asking for help."

"Great gods in the group, it's time for you to perform."

The live broadcast room started to booze, but many people really came forward, many of whom were well-known geologists.

A senior student of a geological university said: "Pet brother, the water flow is easy to distinguish. Throw a leaf into the water and the water flows in which direction."

"I know too."

"But I just saw it."

Chen Lie pointed to the other side of the mountain range and said, "The water here flows towards the mountain range."

Mountains are naturally high places.

Doesn’t the water flow in that direction violate the principles of physics?

"Water flows up high!"

Not only was the top student from the University of Geosciences not surprised, but rather surprised.

"Nonsense? The water flows to the lower part, and the pupils know it!"

"Brother Pet is going to be a monster again?"
