If there is no interference from the outside world, it may be possible to maintain a balance, but if a relatively violent shock occurs, such as an earthquake, large-scale rockfall, volcanic eruption, etc., or if it is thrown into the lake like generations of Haihun Hou,

A lot of corpses and a lot of construction work.

At that time, the bottle of "Fat House Happy Water" that has been shaken violently will suddenly unscrew the cap, and the large amount of carbon dioxide that has reached the critical value will be poured out instantly.

Not to mention the lake water boiling at this time, it is extremely normal for the phenomenon of "water dragon pillars" that are tens of feet high to appear that Yang Wanli heard from folk rumors.

Under normal circumstances, carbon dioxide at that concentration in the air is a non-toxic, harmless, colorless and odorless gas.

But if the carbon dioxide concentration exceeds the normal concentration.

Once it reaches 10%, it will make it difficult for all aerobic organisms to breathe. Soon, the alveoli in the lungs will be paralyzed due to excessive carbon dioxide concentration, resulting in respiratory center paralysis and hypoxia suffocation.

Once it reaches 15%, most aerobic organisms will not even have time to react and will die immediately!

In addition, carbon dioxide is denser than air.

When such a large amount of carbon dioxide pours in a short period of time, the carbon dioxide will form a gas layer tens of meters thick and spread rapidly along the ground.

All aerobic organisms enveloped by this gas layer were as if their noses and mouths were tightly covered by a pillow falling from the sky in an instant, and they were caught off guard and suffocated to death.

See what happened just now and combine it with the details in the rumors.

Wu Liang is almost certain that the current Linghu Lake is such a "terrifying murderous lake"!

Because this inexplicable bubbling phenomenon also appeared in the three horrific murder lakes discovered in later generations. Even if the locals did not know the inside story, they would still come to watch it as a wonderful "spectacle".

"This is a bit troublesome..."

Thinking of this, Wu Liang was no longer in the mood to make "Beggar and Waterbird" and frowned slightly.

Because this problem is simply not something he can solve...

Even in later generations, a relatively stupid "artificial degassing method" was used to target the horrific murder lake.

People will place several floating platforms in the center of the lake, and install an exhaust pipe on the platform that leads directly to the bottom of the lake. Then use a powerful water pump to suck up the water with a high carbon dioxide content at the bottom of the lake and spray it high-speed to high places.

During the high-speed injection process, the carbon dioxide in the water will be released into the air.

In this way, a large amount of carbon dioxide is divided into low concentrations and released slowly in multiple batches. Such a low dose will not cause harm to the breathing of nearby animals.

But even so, the degassing efficiency is extremely low.

According to scientists' estimates, even if a multi-pronged approach is taken, it will take several years to remove all the carbon dioxide currently in the terrifying murderous lake.

What's more, during this process, new carbon dioxide will still be continuously produced under the water...

If this is the case in later generations, Wu Liang will naturally be even more powerless.

The only way he can think of to solve this problem now is the power of nature...

As far as Wu Liang knows, the reason why the Haihunhou Tomb is considered a relatively well-preserved tomb in later archaeological discoveries.

The main reason is that the tomb was damaged during a major earthquake in the Eastern Jin Dynasty. A large amount of lake water poured into the tomb, which made it difficult for tomb robbers who were not capable of underwater operations. Moreover, the isolation of water can also better block most cultural relics.

Oxidation.

Based on this, it can be inferred that the reason why "Spirit Lake" no longer has the ability to be a "terrifying murderous lake" in later generations is probably related to this major earthquake.

In that big earthquake.

The earth's crust moved again, causing the rock cracks at the bottom of the lake to be completely sealed, or the location was advantageous, so that carbon dioxide would no longer accumulate at the bottom of the lake, and the phenomenon of "a vicious lake sucking souls" would no longer occur.

But these are all things for later. Now Wu Liang does not have the power of "Shock Fruit" to summon a major earthquake, nor can he build the "artificial degassing" machine of later generations.

If that's the case, I'm afraid I can only...

Wu Liang frowned and thought for a long time, and finally looked at Yu Ji and said, "Old sir, let's go up the mountain to find the tomb first? Please."

"Easy to say."

Yu Ji didn't refuse, stroking his beard and nodded slightly.

"Huh? Wait a minute, can you still catch the waterfowl? Can you still do the waterfowl?"

Bai Jingjing quickly caught up and asked.

She had already shed a lot of tears for those waterfowl, but now that Wu Liang suddenly stopped mentioning it, wouldn't the tears have been in vain?

"Catch! Some waterbirds will build nests in the woods near the water. You can also catch them when you go up the mountain."
