After everyone comes.

A biology scientist in a white coat stood up from his seat and walked to the podium alone. He was 73 years old. Even though his appearance and figure showed aging, he still walked steadily.

This person's name is Zhao Caizhe, and he is currently the president of the National Academy of Sciences.

At this moment.

The older scientist came to the podium, looked around the entire large conference room, and quietly looked at the senior high-level figures present, with a very serious face.

Zhao Caizhe reached out and opened the simple amplifier on the podium and said in a deep voice, "Everyone, I specially asked Your Majesty to hold this meeting today, which will determine the future life and death of our human beings. To be precise, the life and death of ordinary people like non-evolved people."

"As for why you should use such a simple and primitive instrument, you are not allowed to bring any electronic equipment into the conference room, and we will discuss it later."

"Time is tight, Zhao is here to tell a long story."

Zhao Caizhe focused on these high-level figures, with a complex and unidentified expression in his eyes.

As soon as he opened his mouth, he was shocked by words.

"I'm unfortunate to tell you a tragic fact here."

"We humans are about to usher in a mass extinction of species and be eliminated and destroyed by nature."

When the many big people here heard this, they were shocked and subconsciously stood up with disbelief on their faces.

"What are you talking about?"

"How is this possible? How can we humans be about to become extinct?"

"How dare you talk nonsense here, bewitching people, and dragging him out and chopping him."

"Slowly, I believe that Mr. Zhao is not so stupid and nonsense, so I will never be so sarcastic and nonsense. I'd rather listen patiently and see what Mr. Zhao said."

...

In the end, it was the contemporary emperor Nangong Ji who waved his hand to stop everyone's discussion and said in a deep voice, "My dear friends, be careful, keep listening patiently, and you will understand what it means."

"I am obeying your Majesty's will."

On the podium.

Zhao Caizhe quietly looked at the various reactions and expressions of the people just now, with expressionless faces and calm eyes, and he didn't know what was thinking about.

After receiving Nangong Ji's eyes, he continued to speak out and explain briefly.

"As for why Zhao had this conclusion, please listen to a simple piece of data and understand."

"Under normal atmospheric pressure and oxygen partial pressure, the oxygen concentration that ordinary people can survive normally is 195 to 235, and the value of air oxygen content exceeds 235. For us humans, it is an oxygen-rich environment that endangers life."

"But now, just less than seven days after the mysterious blue ice rain came, the oxygen content in the city where humans gathered has soared to 289."

"I guess you have felt a little uncomfortable recently."

"And in the wild forest, this data is even more terrifying."

"I have sent dozens of elite soldiers to the forest to use instruments to measure the average oxygen content in the air, which has risen to 3123."

Zhao Caizhe looked at the puzzled eyes of everyone present and briefly mentioned, "Maybe you don't understand what this level of oxygen oxygen represents, but Zhao can give you a real example that happened."

"The Carboniferous Period, about 35.5 billion to 29.5 billion years ago, in the ancient wilderness era called the giant insect era, the average oxygen content in the air was about 35."

When it comes to the era of giant insects, some people's expressions are moved and become extremely serious.

According to the ancient fossils excavated so far, ordinary ants of that era could grow about the same age as adult men, and they still survive and hunt in groups. Their living habits are not very different from those of today.

Insects, especially arthropods, were the absolute overlord creatures at the top of the food chain and food network of that era.

But there are also more people who disagree.

I always blindly believe in one thing in my heart, that is, human technology is invincible, and no matter how large an animal is, it is vulnerable to scientific and technological weapons.

It completely ignores whether humans themselves still exist under this oxygen concentration.

Looking at the different expressions of these people, Zhao Caizhe sighed in his heart, a hint of sarcasm and ridicule flashed in his eyes, and he murmured silently, "After all, they are a group of ordinary people who only know how to play power and money..."

"In front of nature, it is just a tiny dust that can be wiped out by waves, and it is optional."

On the surface.

————

Zhao Caizhe's face was still serious, and he said in a deep voice, "Based on the data collected so far, we have obtained a more terrifying news."

"When a new global dynamic carbon-oxygen equilibrium structure is formed and established, the average oxygen content of oxygen in the air will soar to around 4213 to 4867. And this period of time is about one month left."

"The oxygen poisoning effect will cause all species that cannot quickly adapt to the high-concentration oxygen environment to become extinct on a large scale."

"Ha, it's really nonsense, it's mysterious." Among them, a man with a big belly suddenly sneered and couldn't help but sarcastically said, "The concentration of oxygen in the hospital is at least 70, and the oxygen that astronauts suck in space is as high as more than 90."

"Why didn't they die of oxygen poisoning?"

"The key factor of oxygen poisoning is not the oxygen concentration." Zhao Caizhe looked at the contemporary head of the Fu family and secretly mocked himself "Ignorance idiot" in his heart, and explained respectfully on the surface, "Oxygen partial pressure is the key factor that leads to the oxygen poisoning effect."

"Whether the hospital oxygen inhalation mentioned by this adult or the astronaut's space oxygen inhalation, the oxygen partial pressure has been re-regulated by electronic instruments. But in nature, nature will not specifically regulate the oxygen partial pressure for humans."

"Under normal circumstances, the higher the oxygen concentration of oxygen in nature, the greater the oxygen partial pressure, and the two show a positive correlation model."

"The higher the oxygen partial pressure, the more likely it is to have oxygen poisoning effect."

"Even the oxygen concentration that can allow humans to survive normally, as long as the oxygen partial pressure or atmospheric pressure is large enough, it will be enough to allow oxygen to easily extinct all human beings."

He was secretly slapped in the face once by Zhao Caizhe.

Fu Yuanji, the contemporary head of the Fu family, looked blue and red, and glared at Zhao Caizhe with some anger, with his eyes very unkind.

Before the upcoming death crisis, Zhao Caizhe no longer cared about other people's threats.
