Chapter 159 The Third Incomplete Mass Extinction

In spring, the warm rays of light spread all over the world, the ice and snow began to melt, the sea of ​​the canyon began to thaw, the plants began to regain their greenness and youth, and everything came back to life!

And then died.

The low oxygen levels continued throughout the winter. Even in the spring when the plants woke up, there was no sign of improvement. Many creatures began to wake up. Under the influence of the temperature, their blood flow accelerated first, and then the cells recovered. The limbs also began to move.

But during this period, due to the inability to obtain enough oxygen, the vitality just obtained disappeared instantly, the creature began to be in a state of dizziness, the brain could not get enough oxygen, the limbs also became weak, and the creature became panic and fear. Occasionally, various phenomena such as vomiting will occur. After hundreds of seconds, the heart of the creature will stop beating and eventually die.

Nowadays, almost no organisms do not need oxygen, even fungi and plants need it. This phenomenon has brought great damage to organisms, and it is not an exaggeration to call it a disaster.

It's the same as the oxygen disaster that Lin experienced a long time ago, but that time it was because of the presence of oxygen, this time because of the lack of oxygen.

In the jungle where all things were revived, the screams and screams of creatures echoed. Oxygen deficiency is a very painful thing. Some creatures will goug out their eyeballs because of madness, or bang their heads, and then fall on the ground. On earth, into death.

There is only one place, which Lin calls the 'Oxygen Fortress', where the creatures can wake up normally and move normally as before.

But those creatures that lack oxygen. Most didn't get out of the sleeping dens they dug, and they just died in their dens. The state of death is quite terrifying.

Lin's snowball still floated in the wind, watching the tragedy from above the jungle.

The air in spring was supposed to be quite lively, with countless dragonflies and insect swarms flying in the air to reproduce. There are no giant-veined dragonflies in the air, they all died in their nests.

This is a new disaster...

However, Lin managed to avoid the disaster this time. This incident was not a disaster for Lin. Even if the oxygen completely disappeared, Lin would still be able to survive.

But for other species. This is a huge destruction. After a few days and nights, the smell of carrion begins to fill the jungle. The fungi have begun to decompose the corpses of these creatures. Although the fungi also need oxygen, the need is extremely low. The current situation They are hardly the same thing.

The reason for the hypoxia Lin thought about many possibilities.

The speed of this reduction is indeed abnormal, but it is not important, even if the oxygen is restored, these dead creatures cannot be resurrected.

But Lin always felt that the fungus had nothing to do with all this, and now, with the arrival of spring. Fungi began to crawl out of the surface to decompose the mass of corpses that had died from lack of oxygen.

After all, only fungi are new creatures, everything else has been maintained for a long time, and maybe fungi really caused this destruction.

However, although it is destruction. But for some creatures it is new.

That's reptiles.

Oxygen has not completely disappeared, it has only been reduced to a certain extent. Therefore, almost all those who died due to lack of oxygen were large arthropods.

In fact, more than 95% of the species that make up the jungle are arthropods. Some of them can grow to a particularly large size, but arthropods get oxygen through a type of stomata all over the body. If the oxygen level decreases, they will Oxygen is not available normally, and spring awakenings require a lot of oxygen, but they result in death.

Reptiles have an organ called 'lung' that actively draws a lot of air to get oxygen, so they don't die even if they just feel sick when the oxygen level gets low, and they adapt quickly In the current situation, some reptiles have come out to find food.

Food now...it's all over the place.

Reptiles can be said to be a kind of 'bottom' tiny creatures. They usually play the role of 'arthropod prey'. They have been running away in the jungle in panic. They are small in size and can grow to the size of crystal scale lizards. There are only a few, but they can use these giant monsters as food this time.

How will they feel? Will it be amazing? But at the moment, bowing their heads and eating wildly is the key point for them.

In addition, the head worm is also a kind of arthropod. They are evolved from some kind of evolution, but there is no problem with it. Its huge head needs a lot of oxygen, so it has a kind of 'lung'-like ability. .

It doesn't have lungs in its body, but it has a small type of soldier. Lin actually discovered that it was a type of soldier recently. At first, he only thought it was the organ that the head worm grows. The miniature type is called 'oxygen ball', and they are like a ball. , are distributed in a large number in the stomata of the head worms, they will act like lungs, inhaling a lot of oxygen to the head worms, and they do not need a 'queen' to reproduce, they will proliferate or decrease according to the head worm's physical condition, Therefore, the effect of hypoxia on the head worm is very small.

The other units of the head bug have this type of unit in the air hole, so there will be no big problem.

Sure enough, the division-type species have some methods. Because of the division of labor, they can usually cope with situations that various single organisms cannot cope with.

But Lin didn't know what happened to the Inca swarm. I remembered that they didn't have this kind of troops, and I didn't know if there was a drop in oxygen where they went.

Let's see this later, Lin thinks they can be easily solved.

There are no Aztec insects either. Maybe they will have some problems. As far as Lin knows, Montezuma II is still alive, but the large insects like the deep sand bus may not survive.

Next, Lin observed the aquatic organisms in the canyon. Lin found that the reduction of oxygen had almost no effect on marine organisms, including marine arthropods. Marine arthropods do not use stomata but gills to breathe. It can be said that the ocean is basically Not much has changed. Ancient squids, such special creatures, hid in underground caves in winter, and now they are gushing out in large numbers again.

About ten days and nights after the arrival of spring, according to Lin's statistics, almost 99% of the large arthropods died, but the small ones were basically unaffected.

In addition, a large number of reptiles lost their natural predators, and they stood in front of a new jungle...

How will these creatures change? (To be continued...)
