I can deduce the direction of civilization

The ecological negative oxygen ion generator has been developed for three generations, and each generation has a back door, that is, it induces the morphological distortion of macrooxic bacteria and makes the allergic enzyme reaction group violently erupt.

Efficiency, multiplied to a hundred times.

Less than a month.

The oxygen concentration in the ambient air exploded to 24%.

People have been used to 21% oxygen for a long time, and when they suddenly come to an oxygen-enriched environment, the drunken oxygen reaction occurs directly.

some coffee shop.

"Aha..."

People yawn, drink coffee, and look lazy.

Most people in the plains experience fatigue, weakness, and lethargy.

If the oxygen concentration continues to rise, people must wear masks or portable ventilators to venture out, just like in the era of low oxygen.

In the era of low oxygen, the oxygen concentration ratio is 18%, and people need to wear oxygen masks when traveling.

Now, in the era of oxygen enrichment, when the oxygen is 24%, people need to wear hypoxic masks.

Humans have technological means to resist the sudden surge of oxygen-enriched environment.

But in nature, all kinds of creatures and wild animals cannot withstand the oxygen-enriched environment, and fall into a terrible catastrophe.

Three months later.

Oxygen levels rose to a terrifying 27%

A considerable number of people died painfully due to the severe drunken oxygen reaction.

In the natural biosphere, 75% of animals are dead, and some species are on the verge of extinction.

Plants have not been spared either. As oxygen squeezes the space for carbon dioxide, the plant world is also facing a major reshuffle.

half year later.

The oxygen concentration finally stopped rising, but at this time, the oxygen concentration has accounted for 30% of the air!

A large number of animals and plants died, the biosphere became unbalanced, the biological chain was broken, and the vicious circle continued to develop.

All creatures are in danger.

The entire Blue Star was devastated.

[At the end of 2081, people pointed their finger at Tianwen and Shi Wei, thinking that Tianwen and Shi Wei should bear the responsibility, but Shi Wei was not afraid at all, and did not come forward to solve and take responsibility. Tianwen has the most cutting-edge technology in the world, has There are two bases on Mars and the moon, and more than a dozen space fortresses. Now he himself has been hiding in the moon base, monitoring the development of the blue star from a high position, ignoring the clamor of the people in Kyushu, and only dealing with the dignitaries of Kyushu. For Shi Wei, When the dignitaries silenced, everything was fine. After all, the big killer was also a fatal threat to him. 】

[In 2082, based on the calculation based on the 0.16% decrease in oxygen concentration per 5500 meters, people only need to go to the plateau at 21 meters to enjoy the original [-]% oxygen environment. Therefore, the survivors set off for the plateau area one after another. 】

[Among them, only the Fozang Plateau in Zhongzhou, with an average altitude of 4000-5000 meters, is the most suitable for ordinary people to live in. The states have asked Zhongzhou for help one after another. Zhongzhou agreed, but they need to sign the Shenzhou Agreement to protect the rights and interests of Zhongzhou. The states have no choice but to do so. Signed, so far Kyushu is completed, the four seas are one, and Zhongzhou is unified. At this time, the total population is 8000 million. 】

[At the same time, the core elites and wise men of mankind, as well as some dignitaries who are willing to submit to Shi Wei, are accepted by him to go to Mars, moon bases and space fortresses to temporarily avoid disasters, and to engage in scientific research, seeking giant oxygen to break through the mysteries of human life and strength, The dignitaries expressed their approval and support. 】

[In 2090, the giant oxygen crisis that lasted for ten years finally ushered in a big turning point. In order to resist the erosion of the oxygen-rich environment, animals with unstable genetic locks once again staged an evolutionary explosion. Moreover, this evolutionary explosion, the speed Fast and short, beyond people's expectations and imaginations! 】

[Because the genetic lock is too complete for human beings, it has been delayed to open it in time due to the giant oxygen mutation! 】

Chu Tiange stood on the plateau and looked up at the sky.

Today, humans have two camps.

A "camp of nobles in the sky" represented by Shi Wei advocates the era of giant oxygen and seeks a breakthrough in the evolution of life levels.

The other camp is the camp of ordinary human beings headed by the Shenzhou Alliance and Gao Liangjiang. All living beings are flesh and blood. They only want peace, stability, and survival.

Are you born a villain? If there is no Shi Longrui in the main world, will there be Shi Wei in the future?

On the whole, Shi Wei's ambitious personality has a lot to do with Shi Longrui's careful induction.

There must be no Shi Wei in the main world!

Even if there is, there can only be one ordinary teacher, Shi Wei.

For the first time in Chu Tiange's eyes, a murderous intent appeared in Chu Tiange's eyes.

Early 2091.

The hinterland of Zhongzhou.

A well-equipped resource search and intelligence espionage team wearing hypoxic masks came to Rongcheng.

At this time, Rongcheng has been covered by tall plants and has become a paradise for animals and plants to inhabit and multiply.

Not only Rongcheng, but the whole of Zhongzhou, and even major cities in Kyushu are the same, turning into forest cities, with thick vines breaking through the reinforced concrete and merging with the walls.

Human supremacy is in jeopardy.

"Fang team, I found something strange... there is a big tiger... a big worm!"

The lips of the team members trembled, and their voices trembled.

Fang Xiaojun held up a high-power lens to observe the direction of Forest City.

"Is that how courageous you are? Next time, don't tell anyone that you are an elite soldier brought out by our small army. A tiger and a snake can scare you..."

"Fuck!!!"

"Big, big, big tiger! Big worm!"

800 meters away from them.

A huge tiger with eye-catching eyes more than ten meters high was fighting with a giant python tens of meters long and two or three meters thick.

"This is too big!"

Fang Xiaojun opened his mouth wide and muttered to himself.

……

Chapter 53 The Behemoth Attacks

The eye-catching tiger and the black-scaled python fight.

The lush giant trees tens of meters high around them were affected by the battle between the two beasts and snapped one by one.

Fang Xiaojun strictly ordered the team not to make a sound, kept silent, and sent back the battle footage in real time, because the forest city was blocked by tall trees that blocked the sky, and satellites and drones couldn't take pictures.

Quietly wait for the two beasts to fight and fight, they will be very profitable.

suddenly.

There was a gust of wind from behind.

pat, pat!

The viscous, snot-like liquid hit Fang Xiaojun and the others on the head, and it flowed all over their faces.

vomit!

The strong stench is disgusting.

They struggled to control the urge to vomit, and looked up slowly and nervously.

At a glance, flax is sluggish!

It was an Emei monkey magnified more than ten times, not as cute and cute as the Qinling golden monkey.

Its bloodthirsty red eyes stared at everyone, grinned its teeth, and scratched its ears, as if it had found a delicious prey.

The team members only felt the biting coldness go deep into the bone marrow. While their scalps were numb, cold sweat dripped down like beans.

Fang Xiaojun made a decisive decision, raised his hand and fired.

Bang!

"Squeak! Chirp!"

The giant monkey raised his hand to block it.

puff!

A metal peanut pierced through the palm.

Immediately, blood spattered everywhere.

The giant monkey felt the pain and rushed towards Fang Xiaojun and others angrily.

As we all know, the Emei monkey is the most aggressive and has a surly personality. If you provoke it, it will 100% find a chance to sneak back.

Thieves hold grudges.

This is the case before the catastrophe, let alone after the catastrophe.

"beat!"

"Fire!"

The tigers and pythons in the fierce battle stopped fighting, and the two beasts looked at the human team that was ambushing the giant monkey.

In their eyes, there seems to be a flash of wisdom that only human beings can have.

There is a posture ready to try.

Fang Xiaojun took a quick glance, his heart was shocked, and he yelled: "Don't love to fight, everyone evacuates, a big tiger and a python are coming."

The team was shocked to hear that, looking at the two giant beasts staring at them hundreds of meters away, the team members couldn't help feeling timid, and they dared not love to fight again.

The advantage of human beings lies in the possession of advanced technological weapons.

Even though the giant beast is physically strong and quick to move, if you use weapons to bombard it intensively in turn, it won't take long to shoot it into a honeycomb screen, or even use a large-scale killer to plant a mushroom. No matter what kind of powerful giant beast has to be turned into dross and dust.

But at this moment, the ammunition reserve of the entire team is limited to them dealing with one giant beast. If there are two more powerful giant beasts...

Ammunition is simply not enough.

At that time, it may not be possible to say for sure who will win the game.

When fleeing, Fang Xiaojun noticed the mottled words on a wall.

The place where they detect intelligence now, in the oxygen-appropriate era ten years ago, belonged to the area around the Rongcheng Country Zoo.

"Unlucky."

In the end, an elite team narrowly escaped death, half of them died and half of them were injured.

Chu Tiange sat on Dug's broad back, closed his eyes and meditated.

"In just ten years, giant oxygen has spawned a large number of giant beasts, and the era of giant insects has come."

"However, in the human camp, the second genetic lock has not been able to break through the shackles."

"What will they do next?"

There is a BUG that cannot be ignored.

"In just ten years, is the evolutionary explosion of the biosphere a bit too exaggerated?"

Generally speaking, evolution induced by the natural environment is not like the artificial nature of the X virus. Although giant beasts can also evolve through devouring, but in just ten years, they have entered the era of giant insects, which is a bit too fast, too inflated, and too incredible.

According to the historical inference of prehistoric paleontological archaeology, the evolution of a species may require hundreds of thousands, millions, or even tens of millions of years of continuous use and disuse. Some species will not change for hundreds of millions of years, such as Cockroaches, lampreys, horseshoe crabs, nautilus and platypus etc.

[The current system version is too low, the answer does not belong to the scope of this time-space deduction, and it cannot give a completely correct answer, but everything has two sides, everything is caused by oxygen, and the host can focus on oxygen itself. 】

"Oxygen itself?"

Oxygen, chemical formula O2.

Supplying the human respiratory system, transporting to various organs, tissues and even cells, participating in the regulation of life activities and biochemical reactions in the body, it is a necessity to maintain the normal operation of human life.

and many more.

I remember in my previous life, there was a conspiracy theory about oxygen.

Oxygen provides the human body to survive and maintain the status quo of life.

But the word oxidation is not very nice when it is placed on the human body.

On the one hand, it is said that it can promote metabolism and cooperate with the human body to provide energy.

On the other hand, oxidizing the human body, causing people to age and even die, is a chronic poison.

Whether the conspiracy theory is valid or not depends on how individuals view oxidation events and define toxic.

"Two sides... there is a problem with the oxygen itself... the negative oxygen ion generator..."
