Start with a planet hitting the earth

The red dwarf turned into golden light and was swallowed by Chen Yuan.

Chen Yuan's mass grew from 60% of the mass of the sun to 69% of the mass, and his volume became about 75% of the volume of the sun.

"It's not enough. This volume and this mass can't swallow the sun. At least I have to increase the volume and mass to the point where I can swallow the sun, then it can be considered a proper star."

"I have to find the next target."

Thinking of this, Chen Yuan used his perception ability to find the next target.

"Red dwarf..., another red dwarf? 7% of the mass of the sun is too little..."

Suddenly, Chen Yuan 'saw' another star.

This is another red dwarf.

"Twenty-one% of the mass of the sun?"

This is much higher than the first red dwarf.

Chen Yuan now has 69% of the mass of the sun. If he swallows that red dwarf, he will have 90% of the mass of the sun!

In other words, as long as he swallows a few more red dwarfs, he can surpass the volume and mass of the sun!

Thinking of this, Chen Yuan was immediately excited.

"You'll be my next target."

After making up his mind, Chen Yuan set off directly.

He flew halfway.

Chen Yuan noticed a yellow dwarf not far away.

This yellow dwarf is much bigger, half the size of the sun, and about 1.5 times the mass of the sun.

Next to the yellow dwarf, there are six planets orbiting.

The six planets are in a plane, orbiting the yellow dwarf, and look very similar to the solar system.

The six planets, the front four are terrestrial planets, and the back two are relatively large Jupiter-like planets, that is, gas giant planets.

The yellow dwarf is too big, and Chen Yuan has no appetite.

He habitually glanced at the six planets orbiting the yellow dwarf.

For Chen Yuan, who is now a yellow dwarf, the size and mass given to him by the planets are already difficult to meet his needs. However, he used to help these stars clean up the planets next to them when he passed by, so he developed a habit.

After Chen Yuan took a look, his attention was attracted by one of the planets.

The planet was slightly larger than the Earth, and small patches of blue and large patches of green could be seen throughout the planet.

That was the color of the sea and the forest.

In other words, it was a planet with life.

"Has a new civilization been born on that planet? I wonder what the advanced intelligent creatures inside would be like."

Thinking of this, Chen Yuan looked inside with curiosity.

The scene he saw shocked Chen Yuan.

There were many creatures inside.

And these creatures gave Chen Yuan a feeling, that is, big!

Incredibly huge.

The largest of those unknown animals was estimated to be as big as six or seven floors.

The size of other animals was also shocking enough.

Chen Yuan also found that the oxygen concentration in that planet was almost several times that of the Earth civilization where Chen Yuan was originally.

"The creatures on this planet are really big."

Chen Yuan was thinking.

Suddenly, Chen Yuan "saw" a few people through his perception.

They were not like people, but more like primitive people.

These primitive people walked in groups holding huge sticks.

What shocked Chen Yuan was their huge size.

The size was estimated to be five meters tall, covered with black hair, and looked very scary.

"Giant civilization?" Chen Yuan thought subconsciously

"Civilization?" Ya's voice came: "They do have some wisdom, but this is just a short-lived civilization."

"Short-lived civilization?"

"Yes, the planet is currently rich in oxygen, which causes the animals inside to become very large, but this situation will not last long. After a period of time, the oxygen in the planet will slowly decrease until it drops to about 20%. Those animals inside will die, including the civilization you see now."

Oxygen is related to the size of animals.

When the oxygen in a planet is higher and more concentrated, the size of the animals and plants inside will be larger.

Conversely, if the oxygen concentration is lower, the size will be smaller.

Humans like the Earth civilization live in a world with an oxygen concentration of 20.9%.

Perhaps someone will ask, if the oxygen on Earth becomes more concentrated, will humans become larger? Will they become giants?

Actually, it won't.

Humans have adapted to the world of low concentration. For humans, it doesn't mean that the richer the oxygen, the better.

If there is less oxygen, humans will experience symptoms of hypoxia, but if the oxygen is too rich, the human body will not be able to withstand such an oxygen concentration, resulting in premature oxidation and aging of the human body. If the oxygen concentration exceeds 70%, humans will suffer from oxygen poisoning and die.

"Is that so?" Chen Yuan looked at the planet and said, "Then, is there no huge and intelligent civilization in the Milky Way?"

"Yes, but that kind of civilization is a minority. Are you interested in going to see it? I can take you there." Ya's voice was full of interest.

Chen Yuan was slightly startled and said, "Forget it, I have something else to do."

"I knew it."

Chen Yuan retracted his sight and continued to fly towards the target.

According to Ya, that is to say, there are still giant civilizations in this vast universe. Now the civilization of this planet is expected to perish, but there are still giant civilizations in other places.

This vast universe really has everything.

"Wait a minute, if there is a giant civilization? Does that mean there is a Lilliputian country?"

Thinking about it, Chen Yuan suddenly became a little interested.

There is probably no need to think too much about this. The universe is so vast and so big. Since it can produce giant civilization, there must be a Lilliputian civilization.

Chen Yuan didn't think much about it.

"Forget it, these are not important to me. What's important now is to swallow some celestial bodies first, make myself as big as the sun, and then go back to the solar system to see our old friend, the sun."

In the vast universe, he flew for a while and encountered some wandering planets when passing by.

Swallowed them all directly.

However, these wandering planets are almost useless to Chen Yuan now. Swallowing them will not increase the volume and mass much.

Later, he simply chose to ignore them.

Only when it hits head-on, it swallows a little, and the rest is just let go.

That day.

Chen Yuan noticed through his perception that something seemed to be approaching him.

"What?"

Chen Yuan subconsciously refined his perception and locked onto the thing that was flying towards him.

At a glance.

Chen Yuan saw a huge warship, which was flying straight towards Chen Yuan.

This is obviously a warship of a certain civilization, but the question is why a warship of a civilization would fly towards Chen Yuan?

There is only one possibility, their target is Chen Yuan.

Chen Yuan had been bombed by warships before, and this time he saw the oncoming giant warship.

Chen Yuan had a bad premonition.

"Are they coming to bomb me again?"

"They are coming to bomb you." Ya's voice sounded: "I forgot to tell you. There is a blue wave civilization ahead of you. If you follow your path, you will probably eat up their planet alive."

"Ah? In such a big universe, you are going to get scammed just by flying around?" Chen Yuan was speechless.
