Chapter 254 Poison Lake
Ask for a reward, begging for a reward.

--------------

There was no rise in the carbon dioxide accumulation area, and Fang Hong moved forward all the way.

There are no plants in the entire sunken valley, but above, there are lush trees.

The huge leaves on both sides don't let go of any inch of space, and seal the top of the valley. In other words, even if you fly a plane under the clouds, you will probably not be able to find this place.

In fact, the valley did not sink too fast all the way, but fell slowly. When Fang Hong walked a few hundred meters, the entire drop dropped only a little.

"This doesn't look like a valley at all. On the contrary, it looks like a road dug by hand. Of course, it's just like that. I don't see any traces of digging by man."

Fang Hong came here to look for artificial traces.

But don't forget how this island came to be, it is recorded in Captain Kidd's treasure map, there are still a lot of treasures in this place!

At the corner of the valley, there is still a long way to go, but Fang Hong saw a lake at a glance, a lake with light blue water.

"Is this a river channel?"

"It should be. There will definitely be water in the rainy season."

"What the hell is the rainy season, the places covered by clouds for 360 days, five days and three hundred days are divided into rainy seasons and dry seasons?"

Not far ahead was the lake. Fang Hong climbed up the nearby cliff and sat on the two-meter-high cliff top, looking at the lake.

Turning his head around the sky, he didn't know why Fang Hong came to this place.

"It's so cozy, beautiful view."

Just when Fang Hong relaxed, Chao Tian exerted force with his claws, scratching Fang Hong's shoulders, and he didn't know if his skin was broken, and Chao Tian also yelled loudly.

It was on Fang Hong's shoulder, next to his ear, and it was so refreshing that it nearly deafened Fang Hong.

"Why, why."

Under the watchful eyes of all the water lovers, ripples appeared on the surface of the crystal blue Far Island Heart Lake.

Fang Hong obviously felt a shock: "Earthquake? Animals are keen. When an earthquake comes, they can sense it in advance."

"The shock was very small, about magnitude three."

It only shook for more than ten seconds, and Fang Hong was not too excited. However, above, opposite the lake shore, along a circular area of ​​the lake, countless birds suddenly flew up in the woods.

The sky around this oval lake is occupied by birds.

The Asuka didn't hesitate, and all flew out.

"What the hell, a hundred birds chasing the phoenix?"

"Is this court? This is escape!"

Shuiyou told the truth.

Right in front of Fang Hong's eyes, the crystal blue Yuandao Heart Lake suddenly turned blood-red, and the entire lake seemed to be boiling, churning endlessly.

"Is the water boiling?"

That's impossible, except for an atomic bomb, nothing could bring such a large expanse of water to a sudden boil.

If it is not a nuclear explosion, there is only one possibility. The gas escapes, causing a scene similar to boiling water.

Gas escape?What gas?
Under Fang Hong's gaze, the surface of the oval-shaped lake suddenly turned red, and the boiling water was instantly red, covering the entire lake at a speed visible to the naked eye. The whole lake looked like the pupils of a ferocious beast.

In the panoramic shooting, Fang Hong saw another scene.

Under this lake, there are actually many huge oval-shaped bubbles. These bubbles are like the legendary water shelter, covering the entire bottom of the lake.

Fang Hong always felt that this scene was very familiar, but he didn't know what it was, and he couldn't remember where he had seen this scene before.

With the shaking of the earthquake, these bubbles surged up quickly, from being pressed by the bottom of the lake to escaping upwards, some large bubbles began to split into small bubbles, some large bubbles rushed out of the lake, and the small bubbles shattered During the process, the lake water began to turn red, and large and small bubbles gushed out of the lake surface, directly bursting the lake water and flying up, as if the water was boiling.

Fang Hong sat up straight away, remembering where he had seen this kind of scene: "Damn, the volcanic gas is escaping!"

I have seen it in Antarctica, the bubbles in the magma lake surge up and then burst.

It's just because the water is not as viscous as the magma, so many bubbles are directly scattered into small bubbles.

"I finally know where the carbon dioxide comes from!"

Fang Hong turned around and ran away, without further ado, what was it like.

And the torch in his hand was thrown into the carbon dioxide in the valley.

This fucking volcanic gas must have hydrogen sulfide gas. Running with a torch is like running with a burning gas tank, and it will collapse into the sky in a while.

"This island should be a volcanic island. Although there are no traces of volcanic activity, and there have been no volcanic eruptions for many years, the magma is still active. Carbon dioxide enters the lake through the crust and gathers at the bottom of the lake under the pressure of the lake. , turning into big bubbles attached to the bottom of the lake one by one."

"Brother Gun, the gas is so light, shouldn't it float in the water?"

"Haven't you ever drank carbonated drinks? Without external force, carbon dioxide can stick to the bottom of the bottle for a lifetime."

The bubbles when drinking cola are carbon dioxide. When they gather into bubbles, the pressure changes suddenly when the bottle is opened, and they are sprayed out directly. In the air, although the air pressure becomes higher, it will not be sprayed out with Coke.

By the same principle, the earthquake just now caused a large amount of carbon dioxide to escape.

This phenomenon is scientifically known as the 'lake tumbling theory'.

Judging from the behavior of these birds, they seem to have known for generations that this lake is a bird-killing lake, so escape is integrated into their genes, and they will flee immediately when an earthquake occurs.

In fact, carbon dioxide is a poisonous gas. Although there is a lot of it in the air, we are not poisoned because the oxygen content is higher. Once exposed to a large amount of carbon dioxide, it is called a real colorless, odorless and highly poisonous gas. Whole corpses can only be checked to die of suffocation, and it will not be too painful before death, because you have fallen into hallucinations or even fell asleep.

While running wildly, Fang Hong smelled a smell of rotten eggs, which was hydrogen sulfide. Fortunately, he threw the torch quickly.

"The main part of these gases is carbon dioxide, and there are also sulfide gases. The escape of sulfide gases is faster than carbon dioxide. It is estimated that in a short period of time, the oxygen content in this area is seriously insufficient, and it is a restricted area for life."

Of course, that is a short period of time, and the plants will not be affected at all, because once there is no oxygen absorption, the plants will be in the daytime and carry out photosynthesis, and at night, the plants need to breathe oxygen.

It is estimated that these gases will not accumulate for that long.

"Brother Gun, do you need to run so fast, you can't die."

"On August 1986, 8, a large amount of carbon dioxide leaked from the volcanic lake of Nyos. The lake released a small amount of sulfide gas and a large amount of carbon dioxide for a short period of time. According to incomplete statistics, at least 21 people were killed by the poisonous gas, and a large number of livestock died. The village of Gamneo, which is closest to the volcano, was the hardest hit, and only 1740 of the 650 residents in the village survived."

In other words, of course you are not dead if you stay here now, after 10 minutes, there will be no oxygen for you to escape if you want to run.

"What the hell, killing so many people by carbon dioxide?"

"You know why our ancestors stick to the land of China and don't want to communicate with the outside world. Although our country's land is not the most fertile, it is the safest."

At least, there is no such lake in China that can escape volcanic gas.

In fact, this kind of lake is also rare. After all, the Antarctic volcano is so big. When Fang Hong went to investigate, he rarely saw volcanic gas, and the machine rarely detected it. However, the volcano in Kenya National Park escaped water vapor instead of carbon dioxide.

This lake is very rare. There are only three volcanic lakes on the earth that have recorded murders.
