Start with a planet hitting the earth

"Bang!"

A burst of bright light appeared in Chen Yuan's field of vision.

Chen Yuan noticed a supernova explosion in the galaxy not far away.

A star died.

After stars die, smaller ones will become white dwarfs, medium-mass stars will become neutron stars, and large-mass stars may become black holes.

In fact, white dwarfs, neutron stars and black holes are all created after stars evolve and eventually die.

White dwarfs have the lowest mass, so when they die, their body heat is still there, so they appear white.

But when the body heat of the white dwarf is used up, it will transform into a black dwarf.

After a white dwarf becomes a black dwarf, it will take more than 10 billion years to evolve into a black dwarf.

Theoretically, there are currently no black dwarfs in the universe.

Because based on the knowledge Chen Yuan learned from earth civilization, the current age of the universe is around 14 billion.

The time required for a star to transform into a white dwarf, and then into a black dwarf, far exceeds the current age of the universe, so there are no black dwarfs in this universe.

This is also the reason why Chen Yuan cannot see the black dwarf.

"Many stars cannot escape the fate of death as time goes by. Just like the supernova explosions that are often seen, a supernova explosion will cause death, which means that the helium and hydrogen in a star have been consumed. It's clean." Chen Yuan thought to himself.

"Time will slowly pass, and then all the stars will disappear."

"Without those stars, I don't know what would happen to that civilization."

"Without stars, there is only death." Ya gave Chen Yuan a response.

Chen Yuanyi was startled: "Death? Probably not. Isn't your advanced civilization an artificial star?"

Ya Le said: "Hydrogen and helium elements will not increase. Our civilization can use hydrogen atoms and helium atoms to create artificial stars, but we cannot create hydrogen atoms and helium atoms."

"When the hydrogen and helium elements in the entire universe disappear, then all civilizations will die, including me."

"This..., aren't you immortal?" Chen Yuan didn't expect that Ya would die too.

"Even the bodies of my generation, our bodies still need to replenish hydrogen atoms." Ya said: "As long as I have one cell left, I can be resurrected indefinitely, provided that there are still hydrogen atoms in this universe. And , As long as I stay in this universe, I am also consuming various atoms to maintain my body."

"If there are no hydrogen atoms in the universe, then I will be dead."

Ya spoke very casually, as if she didn't care about her life at all.

"I don't want you to die." Chen Yuan said.

When Ya heard this, a bad smile appeared on her face. She crossed her legs and looked at Chen Yuan: "Don't you want to? Are you already in love with me? So you start to feel sorry for me."

Chen Yuan was speechless.

"I'm bored. After so many years, I wonder what my civilization has become."

Chen Yuan changed the topic. Through the vision brought by his perception ability, he looked towards the direction of the civilization he created.

Take a look.

The sight of the scene made Chen Yuan a little depressed.

The planet has entered another era.

You can see high-rise buildings and even space planes.

But the war continued.

Some countries already have space shuttles, while others are extremely poor and seem to have regressed back to the industrial age.

Countries located in war zones are not even in the mood to develop civilization.

In other words, although these people were all created by Chen Yuan, their ancestors were all the more than 30,000 primitive people.

But now they are at war, and they are fighting fiercely.

"I really surrendered and started fighting again." Chen Yuan said: "They were originally the descendants of the 30,000 primitive people I created. They were all people with the same blood. I can understand it when they were invaded by others. , why don’t others invade, why do they still like to fight civil war?”

"It's really incomprehensible."

"Advanced intelligent creatures are all like this." Ya said: "They are competing for resources. In primitive times, wild beasts would kill each other for food and mating rights until they get something that satisfies them."

"In modern times, with wisdom, they compete for more things. In terms of status, it is reputation, status, wealth, power, etc."

"If we zoom in further, we will have to compete for resources. The resources of a planet are limited, so use less. Only when we can compete for resources can a country have the ability to develop."

Ya said casually: "As it continues to develop, civilization will enter the era of nuclear bombs. If a war breaks out in that era, that civilization will most likely perish."

"After a civilization has survived the civil war, the resources on the planet are almost exhausted, so it has to go to the universe to find resources." Ya smiled: "Just like the civilization you destroyed before, that civilization has survived Civilization after the Civil War. Your own planet has been almost destroyed, so you have to look for resources outside...well, that's the planet you created."

"However, they were quite unlucky. It was rare that they survived the civil war. It was rare that they found a planet that could be colonized. They flew thousands of miles there, only to be dismantled into atoms by you."

Chen Yuan was slightly startled, and he said helplessly: "There is no way. No matter what their purpose is, they are invaders. Since they are invaders, they deserve to die. If you want to kill others, you must be mentally prepared to be killed."

Chen Yuan did not think much.

He retracted his attention and went to look.

Chen Yuan saw an interesting phenomenon.

A massive black hole and a small black hole, both of which were attracted by each other's gravity and were approaching.

The small black hole was approaching the massive black hole in a spiral flight direction.

"Black hole swallowing black hole? Interesting."

As a black hole, Chen Yuan often swallowed other black holes, but the problem was that Chen Yuan's swallowing was abnormal.

Although Chen Yuan was a black hole, he could speed up his approach and use extreme swallowing to directly turn off the opponent's gravity.

And now in front of Chen Yuan were two real black holes.

The gravity of the small black hole was obviously not as good as that of the big black hole, so the small black hole approached the big black hole faster.

They got closer to each other.

If it is as expected, the big black hole will slowly swallow the small black hole.

But at this moment.

An unexpected situation occurred.

Chen Yuan saw that the speed at which the small black hole was circling the big black hole was getting faster and faster.

Suddenly, the small black hole was thrown out by the big black hole.

Chen Yuan felt like a ball flying in front of the big black hole and then being kicked away by the big black hole.

This scene stunned Chen Yuan.
