Start with a planet hitting the earth

Chen Yuan was a little confused by the sudden attack of a certain civilization.

Why would a civilization attack Chen Yuan?

Chen Yuan continued to fly in the previous direction.

Through his perception ability, Chen Yuan found that there was an Oort Cloud in the direction directly in front of him.

The existence of the Oort Cloud means that there is a very likely existence like the solar system in front of him.

Chen Yuan stopped outside the Oort Cloud, he turned on his perception ability, and the perception ability rushed into the Oort Cloud.

He saw the situation in the Oort Cloud.

In this Oort Cloud, there is a celestial system.

In the middle is a star, and next to the star, there are seven planets.

And among these seven planets, there is a blue planet.

It looks a bit similar to the earth.

Obviously, this planet is a planet with life.

Previously, the three warships obviously flew out from that planet.

"There is indeed a civilization in front."

"But why did this civilization suddenly attack such a friendly planet to me?"

Suddenly, Chen Yuan subconsciously looked at the direction he was moving.

He understood.

The other party must have used some technology to observe Chen Yuan's existence, and at the same time judged that Chen Yuan would continue to move forward.

If Chen Yuan continued to move forward and entered the celestial system where they were.

With the mass and volume of Chen Yuan's brown dwarf, even if it did not hit the planet they depended on. It would also change the environment of their celestial system due to the effect of gravity.

For their celestial system, it would be devastating.

In other words, as long as Chen Yuan entered this celestial system, that civilization would usher in a mass extinction of life.

Thinking of this, Chen Yuan knew what was going on.

"No wonder that civilization sent warships to attack me, it turned out to be for self-protection."

"This civilization must be an alien civilization, not quite the same as the previous primitive civilization."

After such a long time of interstellar travel.

Chen Yuan also had a little interest. He wanted to see what these advanced intelligent life forms of alien civilizations looked like.

Chen Yuan looked at the blue planet through his perception ability.

Unlike primitive people.

There are advanced creatures on this planet that have limbs like humans, but they are different from humans.

They have long limbs, light green skin, and large heads and eyes.

"For me as a former human, they look really strange."

At this time, Chen Yuan noticed that there was a huge artificial space station outside the planet.

Through the artificial space station, you can see rows of warships inside.

The size of this artificial space station is comparable to half a moon.

The warships that just came to attack Chen Yuan were obviously flown out of that artificial space station.

If Chen Yuan wanted to attack them, he would hardly need to do anything. As long as he flew into their celestial system, they would definitely die.

However, planets with life are rare.

Chen Yuan looked at the celestial system.

There are seven planets around the star.

That star is as big as the sun, and it is impossible to swallow it.

As for the seven planets, the combined volume and mass is estimated to be only the size of Jupiter.

Before Chen Yuan was reincarnated as a planet, he was also a high-level life.

Chen Yuan still has respect for the existence of life.

"Let's go around."

Thinking of this, Chen Yuan changed the direction of his advance, chose a new luminous star point, and headed towards it.

Along the way, Chen Yuan absorbed the wandering planets he saw.

Since Chen Yuan became a brown dwarf, he swallowed the wandering planets to gain mass, and his volume also increased.

"Brown dwarfs have the ability to ignite tritium. When I swallowed other planets, I gained more tritium. The more things that can be burned, the larger the burning range, and the larger the volume?"

In the astronomical knowledge that Chen Yuan had learned on Earth before, he did not know much about brown dwarfs.

So, Chen Yuan could only guess at the volume growth of brown dwarfs at this moment.

Planets have a volume limit, and the size of Jupiter is already the volume limit of planets.

There are planets that are much larger than Jupiter, and the reason why those planets can exceed the volume limit of planets is mostly because there is a star next to them. They are baptized by the heat of the star, causing their volume to expand.

As a brown dwarf, Chen Yuan can expand to the current size only because the tritium in his body is ignited, and then Chen Yuan obtains enough heat to expand his body.

Therefore, Chen Yuan speculated that the reason why his size would increase after swallowing other celestial bodies was because he obtained more fuel.

"In other words, as long as I continue to swallow, swallow more planets, and obtain more mass, my size will also grow."

Chen Yuan thought of the binary star system formed by the two brown dwarfs he encountered before.

"In the binary star system composed of brown dwarfs that I encountered before, one of the smaller ones had a diameter of 50% of the diameter of the sun."

"In other words, as long as my diameter exceeds 50% of the diameter of the sun, I can swallow that brown dwarf?"

"But if I want to have a diameter that exceeds 50% of the sun, I don't know how many Jupiter-sized planets I have to swallow."

Chen Yuan continued to fly forward.

Chen Yuan was aiming at a light point in the universe, but he was only halfway there.

Chen Yuan found that the light spot next to him was getting brighter and brighter.

But the light spot he was chasing gradually dimmed and finally disappeared.

"Gone?"

Chen Yuan understood it all at once.

Some lights come from very far away, hundreds of light years away from here, thousands of light years away.

In other words, when some lights are emitted and seen by Chen Yuan, hundreds of years have passed.

Maybe during this time, the star has died.

"Change the target." Chen Yuan looked around and found the brightest star.

After locking the target, he set off and flew in the direction of the star.

In this way, Chen Yuan continued to swallow the wandering planets he encountered while continuing to fly in the direction of the star.

What that star is, Chen Yuan doesn't know.

It may be a star, it may be a planet, and of course it may be a star that has burned out thousands of light years away.

He only needs a target now. After all, in this vast interstellar space, it is very boring to have no target.

In this way, Chen Yuan didn't know how long he had flown.

The mass of the wandering planets he devoured on the way was close to five Jupiters, and the mass he now possessed was twenty-two Jupiter masses.

And to become a star, one must have 80 Jupiter masses.

Only fifty-eight more Jupiter masses are needed, and then Chen Yuan can become a real star.
