The wind is whistling.

Yellow sand fills the sky.

In the ruins of the city, a single-family gymnasium stands proudly.

No matter how big the wind and sand are, there is nothing to do about it.

This stadium is now the last shelter and hiding place for more than 10,000 surviving humans.

No matter how great the catastrophe from heaven comes, there will eventually be a gap that will leak out, allowing human beings to survive, allowing human beings to crawl forward, and making human beings difficult to breathe.

However, this is by no means a mercy from heaven.

It is easy to die, and it is not easy to live.

The dead are ignorant.

In order to survive, the living will be in awe and fear.

Because of awe, because of fear, God is a majestic God, and human beings are humble human beings.

After the magnetic earthquake, there is the earthquake.

The earthquake was followed by a sandstorm.

Are there any other disasters after the sandstorm?

Did the heavens leave a way for mankind to live?

How can humans survive?

In the gymnasium, among the more than 10,000 surviving people, except for Jiang Mantian, no one had a definite answer in their hearts.

In fact, even Jiang Mantian himself doesn't know how far he can lead everyone.

But he wasn't very sad.

Anyway, there must be ups and downs, there must be life and destruction, and no one can escape the reincarnation of the world.

Anyway, even the universe that has existed for 13.7 billion years will disappear one day.

However, if destruction must come, Jiang Mantian also hopes to postpone this day as much as possible.

Because he can't live up to the decades of day and night study, the ardent expectations of more than 10,000 pairs of eyes, and the glimmer of life left by God for mankind.

So, he opened his mouth and slowly explained to everyone.

"The universe began with the Big Bang and has been expanding since its inception. The rate of expansion, over time, decreases from year to year. When the rate of expansion becomes zero, the universe enters a cycle of great contraction! Today, this is the tipping point. ”

"Perhaps, there will be tens of billions of years between the universe entering the Great Contraction Cycle and the real demise of the universe, but for us human beings, from this day on, it means the arrival of the end times!"

Jiang Mantian held the dusty billiard table with one hand, and moved gently on the world map of the desktop with the other.

His voice was hoarse, his expression was solemn, his hair was unkempt, his face was black and gray, and the bottle-bottom glasses on the bridge of his nose, one of which had been shattered, looked very funny.

However, everyone listened attentively.

"So, Mr. Jiang, what will happen to the great contraction of the universe? Why do so many people die of cerebral hemorrhage for no apparent reason? Why did there be earthquakes and sandstorms?"

The person who asked the questioner was called He Dali, a third-year student in the Department of History of NUS, who had thick eyebrows and big eyes, broad shoulders and a round waist, resembling an iron tower.

As his name suggests, he is good at shot put, javelin, weightlifting and other power events, and has won several major championships with world record breaking results.

After the catastrophe, Jiang Mantian was carried out of the ruins of the building by He Dali, and during the sandstorm, it was thanks to He Dali who pulled him, otherwise, he would probably be buried in the sand.

Jiang Mantian straightened out his thoughts, picked out the key points, and said concisely: "The great contraction of the universe will first lead to the reversal of the geomagnetic field, that is, the reversal of the north and south poles of the earth. ”

"The geomagnetic flip has four important effects on us:

First, when the geomagnetic field is flipped, it will produce a very strong magnetic shock, which will cause all charged or magnetic life forms to have different degrees of discomfort and even death.

That's why so many people died of cerebral hemorrhages before. Those who died were all because the magnetic induction of the brain was too strong, and the body was too weak to withstand it.

Magnetic shock will also weaken, disappear or even reverse the magnetism of the original permanent magnet, so many electrical appliances are now unusable.

However, magnetisms theoretically only happen once, and now that they have passed, we don't need to mention them again.

Second, when the geomagnetic field is reversed, it will produce natural disasters such as global earthquakes, tsunamis, tornadoes, and subsidence, causing a large number of casualties in the world.

Everyone has seen and experienced this, so there is no need to say more. ”

A young female teacher asked, "So what are the last two influences?"

This female teacher is called He Tingting, wearing washed blue skinny jeans, pure white knitted sweater, simple and elegant temperament, beautiful appearance, perhaps because of staying in school all the year round, exuding a strong bookish atmosphere.

After the earthquake, Jiang Mantian had been in a coma, but she woke him up.

Jiang Mantian nodded slightly, took off the broken glasses covered with a thin layer of ash, and rubbed his sore eyebrows.

"The third effect, when the geomagnetic field flips, will cause a temporary loss of the magnetosphere above the world.

Without the protection of the magnetosphere, a large number of cosmic rays and high-energy charged subatomic particle streams will quickly attack the world's lifeforms, and all living things in the world will appear in different directions in the following time.

The fourth effect, after the geomagnetic reversal, under the new world magnetic field, the human brain will be completely liberated.

We know that the human brain usage rate is basically less than 5 percent, and more than 95 percent of the functions have not been developed. Under the new magnetic poles, the human brain will be used at a terrifying rate of more than 95 percent. ”

He Dali's eyes lit up and he asked, "That is, human beings will become twenty times smarter?"

"With more than 95 percent brain usage, it doesn't necessarily mean getting smarter or having a better memory, but other new abilities may emerge. Every individual will not be exactly the same. Moreover, the liberation of this brain is not done instantaneously, it requires a process. ”

A teacher asked, "You said that the geomagnetic flip will only happen once, which means that the rest of us will not die like those who suffered cerebral hemorrhages before?"

In the billiard room, hundreds of teachers and students eagerly looked at Jiang Mantian, waiting for a reply.

In Huaxia, the name Jiang Mantian is simply known to everyone, and no one knows it.

As the only natural scientist in the history of the Nohard Prize who has won three awards in the fields of physics, chemistry and medicine, and as a young professor who has won the prize at the age of 36 and enjoys special national allowances, the news media have reported and broken the news about him in a series of articles, and they are full of details.

His academic achievements and character are well known.

Therefore, his words are credible.

"Yes. ”

Jiang Mantian affirmed: "The threat we are facing now is the imminent steady stream of natural disasters and the extraordinary evolution of all other species. ”

"But we humans ourselves will evolve, and this is also an opportunity. He Dali's heart swelled with a trace of inexplicable excitement and expectation.

Jiang Mantian smiled bitterly and shook his head.

If the evolution of humanity needs to be exchanged for the extinction of most of its kind, then what is the point of such evolution?

"Professor Jiang, what should we do next?" He Tingting had been standing beside him, knowing that the difficulties that human beings would face next were probably far greater than he had imagined.

Jiang Mantian pursed his lips lightly.

For this catastrophe that mankind will inevitably face, Jiang Mantian has imagined it thousands of times in his mind.

He has been frantically engaged in scientific research for decades, and his fundamental motivation is nothing more than to deal with disasters in advance.

Because he had expected it in his heart, he was not very frightened or sad when it really came, but only a deep sense of powerlessness.

In the past, he was a little afraid of death.

Because before the disaster strikes, he must race against time to use all the time to continue the scientific research work and tell everyone the predictions.

But now he was not afraid.

First, because his most important research topic has been completed by today, and this research report has been sent to the relevant state institutions, and he has fulfilled his responsibility;

Second, he also thinks that people are actually going to die, sooner or later, it is not a big deal. No matter how long a person's life is, it is just a fragment of time. Since the death of one person is not a big deal, the death of a group of people and the destruction of the entire human race is probably nothing more than that!

Looking at He Tingting's beautiful face, long eyelashes, and watery eyes, he suddenly thought that he had missed too many things in his past life.

If he could choose his life again, he probably wouldn't be a scientist again.

Isn't it nice to be an ordinary person honestly?

But unfortunately, he is not an ordinary person.

Therefore, he must use his achievements in theoretical research to predict the future situation and lead these tens of thousands of surviving teachers and students out of the predicament and towards a new life.

This is a responsibility that he must shoulder.

Of course, He Tingting didn't know what Jiang Mantian was thinking when he looked at her, she just looked at Jiang Mantian quietly, waiting for him to show everyone the way.
