I know this ancient god

What is a neutron star?

Neutron stars are the densest stars besides black holes. It is one of the few possible endpoints after a star reaches the end of its evolution and undergoes a supernova explosion due to gravitational collapse. Its density is many times greater than any material on the Ziwei star.

Each cubic centimeter of neutron star material weighs more than 100 million tons, which is 100 billion times the density of water. If the Ziwei star is compressed like this, the diameter of the Ziwei star will be only 22 meters!

The neutron star in front of them has a diameter of nineteen kilometers. If it were a few kilometers more, it would collapse inward to form a black hole.

It is such a terrible extreme star, and it has been tamed. While Tang Xuan and Lin Wan were looking at each other, a soft female voice came into their hearts.

"Welcome, guests from afar."

Tang Xuan was shocked.

Where does this sound come from?

Has the other party discovered us?

Tang Xuan was a little nervous, although he didn't hear any malice in the voice.

Not only Tang Xuan and Lin Wan heard the sound, but also the other billion people on the motorcycle, but the other party did not continue talking, but took practical action.

Strong gravity acts on them, sucking them towards the strange galaxy.

They were still far away from this weird galaxy, but they passed through a black tunnel on the way, and after leaving the tunnel, they arrived inside the weird galaxy.

"ah!"

Tang Xuan heard the screams of the passengers behind him.

In fact, he had always heard screams, but they were particularly loud at this time.

Because they are almost attached to the surface of the steel planet.

Tang Xuan saw a series of huge buildings on the surface of the planet. These buildings were so huge that they gave people a wrong visual perception, as if they were less than one meter away from them.

Tang Xuan also felt an atmosphere of deathly silence.

The planet was completely covered by giant buildings. Tang Xuan could not see any living creatures or man-made flying objects. The surface of the planet was silent.

Do people on this planet live underground?

Tang Xuan couldn't help but think.

At this time, a gentle force pushed them away.

Tang Xuan knew that this was also gravity.

Gravity is one of the greatest forces in the universe. Everything from cells to black holes is affected by it.

If the planet in front of us is really a neutron battle star, then it is very reasonable that it has such a delicate ability to manipulate gravity. After all, if organisms want to gain a foothold on a neutron star, they must first fully control its gravity.

Feeling the effect of gravity on his body, Tang Xuan's soul was shocked. He was convinced that what he was seeing now was a neutron battle star transformed into a weapon by an unknown advanced civilization.

Although it is a tiny thing, it can easily destroy a star with a simple impact, leaving itself unscathed.

In science fiction, a neutron battle star is a river system-level battleship of a god-level civilization. As long as a civilization has a neutron battle star, it can run rampant on a huge astronomical scale.

No wonder this is an A-level treasure.

As long as he gets an advanced technology from the neutron battle star, it will be enough for the Federation to use it for who knows how many years.

The soft female voice from before sounded again: "The trial is about to begin. Can you please go back to your own planet?"

Tang Xuan's ears caught that word keenly.

Trial!

"I can let them return to the planet." Tang Xuan said without hesitation, "But I want to ask a few questions."

After he finished speaking, he waited with bated breath for a response.

He believed that the people on Neutron Battle Star could hear him.

Tang Xuan didn't wait long.

"Hello, young traveler."

A soft female voice sounded in Tang Xuan's mind. This time it was a separate communication and no one else could hear it.

Tang Xuan suppressed his excitement: "Greetings to you, powerful unknown civilization. Where is this place and what is the trial?"

The soft female voice replied: "Without a common frame of reference, coordinates are meaningless. If your civilization can get good results in the trial, even if it fails, I am willing to provide you with a star map within one million light years nearby. ”

The star map is the map of the interstellar era.

The soft female voice continued: "The trial is to find a successor for the Patriotic mothership by testing offensive, defensive and strategic wisdom."

Tang Xuan was stunned.

Looking for a successor for the Patriot mothership?

What does it mean.

Tang Xuan looked up at the Neutron Battle Star in front of him, and his heart rate suddenly increased.

The soft female voice seemed to understand Tang Xuan's doubts. She explained gently: "The small star in front of you is a neutron star that has been transformed into a war weapon. It is the pride and last legacy of our Hill civilization. Its name is As a Weiguohao."

"The heir is"

Tang Xuan's breathing became rapid.

"All the citizens of Hill Civilization have died in the battle, leaving only this neutron battle star. According to the order of the Supreme Commander, I have the obligation to find a new successor for the Patriot and pass on the glory of Hill Civilization Go down."

It sounds like the mother civilization of the Weiguo has been destroyed in the war, and only this neutron battle star is left.

Tang Xuan's eyes turned slightly red: "As long as you pass the trial, you can inherit the title of Weiguo. Are there no other conditions?"

The soft female voice replied: "In addition to defeating the competitors in the trial, the successor also needs to add the historical part of the Hill civilization in the Weiguo database to the history curriculum of his civilization; interested citizens cannot be prevented from studying Hill. Civilization; you cannot fly the Patriot to carry out unjust military operations.”

Among these three requirements, the first two are to rebuild the inheritance of Hill Civilization, and the last one is to ensure that the Weiguo is not used for matters that violate the values ​​of Hill Civilization.

Tang Xuan hesitated and said: "Justice?"

Different civilizations have different definitions of justice.

If the justice of Hill's civilization happens to be the evil of the Federation, then even if he gets the neutron battle star of the Patriot, he will not be able to fight on the Patriot.

The soft female voice dispelled Tang Xuan's worries: "The Weiguo has been connected to your civilized computer. We will not bully the weak or hurt the innocent. Our justice is similar."

"What is the specific content of the trial?"

Tang Xuan asked.

The soft female voice declined: "The trial has not started yet, and I cannot reveal the content of the trial. Now can you let your civilized citizens return to the planet?"

This time there was a hint of urging.

Tang Xuan nodded slowly.

[Cosmic Class Fancy Motorcycle Driver] Canceled!

The seats arranged in a fan shape fell to both sides, and dense meteors appeared in the sky of Ziwei Star, like a peacock fluttering its gorgeous feathers.

Tang Xuan's body also fell downwards, but at the last second, he suddenly had a new question.

He asked: "You said that all the citizens of your Hill civilization died in the war, then who are you?"

The soft female voice did not answer. The trial was about to begin. She had other things to do and had already turned her attention away from Tang Xuan.

But the answer seems self-evident.

Tang Xuan turned his attention to the Neutron Battle Star not far away.
