Sergei's face suddenly appeared, completely disrupting Chen Feng's thoughts.

He spent three days specifically re-verifying, and finally determined that Sergei was indeed the highest target of almost all animals' attack instincts.

Moreover, five hundred years have passed, and the locking intensity of this target has not diminished at all.

This made Chen Feng puzzled.

Is Sergei really alive?

Theoretically impossible.

Even his own lifespan was no more than three hundred years old, there was no reason for Sergei to live longer than him.

Sergei did not die in that catastrophe, but survived until now through human body cryopreservation?

Chen Feng thought this was impossible.

In the eighth timeline, he has seen an almost complete human civilization in the 31st century.

Various black technologies emerge in an endless stream, including plant-based battleships and antimatter Mars power warehouses.

But there is one technology that has not been broken through.

Scholars thousands of years ago had this dream, and there are actually technology companies that have made it a business, charging about 500,000 US dollars a year.

But in the eighth timeline, where the civilization level has exploded and can even overturn spherical battleships, this technology still exists only in fantasy, and research and development was stopped as early as the 26th century.

The brilliant scholars of the School of Life Sciences do not even have the courage to restart research.

It is the seemingly simple, but actually mysterious human body freezing technology.

It is very simple to freeze a person's body instantly without causing any harm, and then thaw it steadily to restore the heartbeat of life.

Humans were able to do this by the end of the 21st century.

On the surface, this indicates that the technology of human cryopreservation has matured.

However, this is not the case.

Elderly people who are about to die have become volunteers and have been frozen for six months, one year, ten years, twenty years, fifty years, one hundred years, or even longer, before being thawed.

This super-large experiment spanned hundreds of years of history, several technological eras, and took a long time, with huge amounts of manpower and material resources invested.

But the result is regrettable. The revived people can temporarily restore their heartbeats and move, but their minds are blank, just like the blank people who appeared in the seventh timeline.

These people's bodies are still alive, but their minds have disappeared. They are no longer alive, but have become a pile of meaningless organic matter.

And these resurrected volunteers soon completely lost their life breath and withered irreversibly.

After testing, when the freezing time is shortened to less than one ten-thousandth of a second, the volunteers can live like normal people, but their minds are still zero, worse than a baby who has just fallen to the ground. However, they still have the ability to learn, and can still master language and form a new personality after a period of time, but they will show all-round differences from their original personality, and this difference is basically in the worse direction.

The final research conclusion pointed out that only the human body can be preserved by low temperature freezing, but not the quantum storm that is eternally moving in the human brain.

When the body is frozen and the phosphorus atoms in the human brain stop trembling, the originally regular quantum collapse vortex loses its support and immediately disappears silently.

Therefore, unless humans can fully study the Grand Unified Force and master the absolute quantum freezing technology that is at least one level higher than the space freezing thread of the spherical battleship, human body freezing technology is meaningless and is just an unrealistic fantasy.

But this is unrealistic. The 31st century humans in the previous timeline are still infinitely far away from completely mastering the Grand Unified Theory, let alone Sergei in the 26th century in this timeline.

Even the most talented people have to talk about basic logic.

From Chen Feng's observation of the ruins of the Earth's cities, it is impossible for humans to possess such technology when the doomsday catastrophe comes. He didn't even see a part involving the cutting of the unified force.

Therefore, Sergei could not be alive today.

Why is this?

Chen Feng racked his brains but couldn't figure it out.

In the end, he chose to respect relatively objective facts, put aside all inferences, and assume that Sergei really exists and is still alive.

So where is this genius hiding?

Where is his secret base built?

How can I find him?

Almost all animals in the world are searching for him.

How can I find him before the animals?

Chen Feng spread his hands. Just because I am Master Chen, I am more powerful than all the animals on the entire earth combined?

Ridiculous.

In short, he found himself a new trouble.

He began to control Morning Breeze 1 to expand its range of activities again, collecting more usable parts while trying to find traces of human activities and humans.

The maximum flight speed of Morning Breeze 1 is 2,100 kilometers per hour,

but he can usually only set it to a slow patrol of 200 kilometers per hour.

There are two reasons.

First, with the current computing power he has, when the flight speed exceeds 400 kilometers per hour, the server will not be able to synchronously convert the information collected by the gravitational wave detector into a projection image, and can only give out a large number of digital signals. It is too difficult for him to use his brain to read such signals. This is the disadvantage of the auxiliary computing ability not being able to keep up with the performance of the detection equipment, commonly known as top-heavy.

Second, even if he cruises at a speed of 400 kilometers, his brain cannot bear to observe the three-dimensional projection with his naked eyes, and he cannot see it so carefully, which is equivalent to being blind. Without a smart super intelligence to help him filter information in advance, relying solely on a pair of naked eyes and brain seeds, his mind will collapse.

Patrolling at a speed of 200km/h is already his limit. The ability to quickly analyze information he has demonstrated is much stronger than that of the genius girl Han Yu who has the same specialty in the previous timeline.

With the amount of information his brain receives per second, a normal person would explode on the spot after just one look.

One day passed, and nothing was gained except for moving a lot of garbage into the base.

Master Chen's temples were swollen and painful.

Two days later, his temples were even more swollen.

Three days...

half a month passed, and it was April 25th.

In order to refresh his mind and withstand the fatigue of this high-load operation, Chen Feng drank about 20 kilograms of tea in this half month, an average of more than one kilogram a day, and his food was full.

His footprints were left everywhere in the five continents, but he still gained nothing, which made him very embarrassed.

Looking at the aerospace-class spaceship that had been built to one-third, Chen Feng thought silently, could it be that the aerospace spaceship has been built, but no one has been found?

Then should I leave or not?

This is a problem.

So embarrassing.

Just when he was about to give up the search and start building a spacecraft, things finally took a turn for the better.

On the evening of April 25, when he docked the Morning Breeze 1 on a small island and set up a juice bench on the beach, preparing to take a vacation, he encountered an unexpected but reasonable attack.

A giant whale suddenly emerged from the sea and tried to swallow him.

Chen Feng was lying on the chair and was too lazy to move. He picked up the remote control and controlled the only weapon on the Morning Breeze 1. A plasma high-explosive cannon opened fire and hit the giant whale in the head.

Master Chen said it was tasteless and had a big meal. He commented that the meat was not very good and tasted bad.

However, his good habit of picking up garbage prompted him to use an engineering machine to dissect the whale, trying to find special parts inside the giant whale.

Before starting work, he used a gravitational wave detector to perform a full-body CT scan on the giant whale, and found something unexpected.

It was a palm-sized square box.

Chen Feng was immediately ecstatic, thinking that this was a treasure like a black box.

He didn't want the information in the black box, which was meaningless.

He was interested in the possible smart chip inside, which could really save his life.

After he carefully dug the square box out of the giant whale's belly, he wanted to call the police on the spot.

Are you kidding me!

What the hell is this headphone jack?

He pressed the button again, and the box opened with a click.

He saw a familiar magnetic needle probe and a replica CD without any text inside.

After a simple disassembly, he burst into tears.

This thing is definitely a CD player that was eliminated in the early 21st century!

What the hell is a CD?

What I want is a quantum chip, and you give me a CD and send me away?

Are you crazy, whale? What era is it now? Why do you have a CD player in your stomach?

Are you still a whale that can listen to music?

With the idea of ​​not giving up until he sees the Yellow River, he had to know what was in the CD, so he took the CD back to Morning Breeze No. 1.

For safety reasons, he made a copy first, then he repaired the damaged capacitor in the CD player, soldered the positive and negative poles of the alkaline battery with tin, plugged in headphones, and pressed the play button.

The next moment, Chen Feng suddenly burst into tears.

He heard Zhong Lei's voice.

This is a song.

A new song by Zhong Lei that he knew existed but had never heard before. He

still remembered that night, when the two were in love, Zhong Lei said that she had vaguely caught the inspiration of the love song and would be able to come up with a finished product in about a day or two.

At that time, Chen Feng was still full of expectations, but he only regretted that he could not listen to it before "leaving".

This time when he came to the afterlife, he saw the doomsday where all record carriers had been destroyed. He thought he would never have the opportunity to preview the new song that Zhong Lei wrote for him in advance, and he had no illusions in his mind at all.

However, on this small island, there is a ray of hope after a dark period.

This song appeared in his ears in such a mysterious way.

Chen Feng was instantly mesmerized by Zhong Lei's storytelling voice, which seemed to vent her gentle yet heart-warming feelings in a subtle and wild way.

After a long time, he slowly took off his headphones and looked at his watch. Three hours had passed before he realized it.

The moon was high in the sky, and the sky was full of stars.

The sea breeze blew, and the waves surged, coming and going on the beach.

The leaves of the coconut trees overhead rustled.

There was only one boat, one person, and one robot on the quiet island.

Chen Feng looked out in the starlight, and all he saw was the dark and boundless ocean.

This was clearly an extremely lonely world, but his face was peaceful and tranquil.

Chen Feng looked down at the CD player in his hand and kept grinning.

For half a year, 182 days, he hadn't heard a single voice from other people.

He almost forgot that he was an individual, and also forgot the motivation to move forward.

He knew it was not good, but sometimes he was totally out of control.

Loneliness can really kill people sometimes.

Zhong Lei's melodious singing voice brought him back to reality from the collapsing virtual world in such an indescribable way.

Chen Feng grinned and reminded himself.

Yes, she is still waiting for me to go back in the 21st century.

I may really have nothing this time, but at least I still have the 21st century.

Silently, perhaps Chen Feng was inspired by "Happiness to the Nth Power", perhaps Zhong Lei's singing once again ignited his emotions, or perhaps the recent excessive tea drinking caused his mind to be too active.

An unprecedented and violent quantum storm once again rose in his mind.

He once again immersed himself in a state of meditation and deep thought.
