What is a neutron star?

Neutron stars are the celestial bodies with the largest density except black holes. They are one of the few end points that a star may become after a supernova explosion occurs through gravity collapse. Their density is many times greater than any matter on the zimuth star.

Each cubic centimeter of neutron star has a weight of more than 100 million tons, which is one million times the density of water. If Ziwei Star is compressed into this, the diameter of Ziwei Star will be only twenty-two meters!

The diameter of the neutron star in front of them is nineteen kilometers. If there are a few more kilometers, it will collapse inward to form a black hole.

It was such a terrifying extreme astral body that was actually tamed. Just as Tang Xuan and Lin Wan looked at each other, a gentle female voice came into their hearts.

"Welcome to you, guests from afar."

Tang Xuan was shocked.

Where did this sound come from?

Has the other party discovered us?

Tang Xuan was a little nervous, although he could not hear the malice from this voice.

Not only Tang Xuan and Lin Wan heard this voice, but more than one billion people on the motorcycle also heard it, but the other party did not continue to speak, but took practical actions.

The strong gravity acted on them, sucking them towards the weird galaxy.

They were still far from this weird galaxy, but halfway through a black tunnel, they left the tunnel and reached the interior of the weird galaxy.

"ah!"

Tang Xuan heard the screams of the passengers behind him.

In fact, he always heard screams, but it was particularly loud at this time.

Because they almost stick to the surface of the steel planet.

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

Tang Xuan also felt a dead atmosphere.

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

Do people on this planet live underground?

Tang Xuan couldn't help thinking.

At this time, a gentle force pushed them into the distance.

Tang Xuan knew that this was also gravity.

Gravity is one of the greatest forces in the universe. From cells to black holes, everything is affected by it.

If the planet in front of you is really a neutron war star, then it is very reasonable to have this delicate ability to manipulate gravity. After all, if a creature wants to gain a foothold in a neutron star, it must first fully control its gravity.

Feeling the effect of gravity on him, Tang Xuan's heart was shocked. He was sure that what he saw now was a neutron war star transformed into a weapon by an unknown higher civilization.

Although it is a small matter, it can easily destroy a star with just a fancy impact without any harm.

In science fiction novels, neutron warships are river-level warships of god-level civilizations. As long as a civilization has a neutron warship, it can run rampant under a huge astronomical scale.

No wonder this is a Class A treasure land.

As long as he gets an advanced technology from the neutron war stars, it will be enough for the Federation to benefit from it for countless years.

The soft female voice sounded again: "The trial is about to begin. Can you please return to your planet?"

Tang Xuan's ears keenly captured the word.

Trial!

"I can get them back to the planet." Tang Xuan said without hesitation, "but I want to ask a few questions."

After saying that, he held his breath and waited for a response.

He believed that people on the Neutron War Star could listen to his words.

Tang Xuan didn't wait for a long time.

"Hello--young traveler."

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

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

The gentle female voice replied: "There is no point in coordinates without a common reference system. If your civilization can achieve good results in the trial, even if it fails, I am willing to provide you with a star map of a nearby one million light years."

The star map is the map of the interstellar era.

The gentle female voice continued: "The trial is to find the successor to the Mothership of the Defense Kingdom by testing offensive, defensive and strategic wisdom."

Tang Xuan was stunned.

Looking for successors for the Mothership of the Wei Kingdom?

What does this mean...

Tang Xuan looked up at the neutron war star in front of him, and his heartbeat speed suddenly increased.

The gentle female voice seemed to know Tang Xuan's doubts, and she explained gently: "This small star in front of you is a neutron star transformed into a war weapon. It is the pride of our Hill civilization and the last legacy, and its name is Weiguo."

"That successor is..."

Tang Xuan's breathing became rapid.

"All the citizens of the Hill civilization have been killed in battle, leaving only this neutron war star. According to the order of the Supreme Commander, I have the obligation to find a new successor for the Weiguo Name and pass on the glory of Hill civilization."

It sounds like the mother civilization of the Wei Kingdom has been destroyed in the war, leaving only this neutron war star.

Tang Xuan's eyes were slightly red: "As long as you pass the trial, you can inherit the name of the Kingdom of Defense. Are there any other conditions?"

The gentle female voice replied: "In addition to defeating competitors in the trial, the successor also needs to add the historical part of the Hil civilization in the database of the Vatican database to the historical course of his civilization; it cannot prevent interested citizens from studying the Hil civilization; it cannot drive the Vatican to conduct 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 name of the Kingdom of Wai is not used for matters that violate Hill civilization's values.

Tang Xuan hesitated and said, "Justice?"

Different civilizations have different definitions of justice.

If Hill's justice happens to be the evil of the Federation, even if he gets the neutron war star of the Guardian Kingdom, he will not be able to drive the Guardian Kingdom to fight.

The gentle female voice dispelled Tang Xuan's concerns: "The Weiguo has been connected to your civilized computer. It does not bully the weak, nor does it hurt the innocent. Our justice is similar."

"What is the specific content of the trial?"

Tang Xuan asked afterwards.

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

This time it was a bit urging.

Tang Xuan nodded slowly.

[Cosmic Fancy Motorcycle Driver] Cancel!

The fan-shaped seats fell to both sides, and dense meteors appeared in the sky of Ziwei Star, like peacocks shaking their gorgeous feathers.

Tang Xuan's body also fell, but in the last second, he suddenly had a new problem.

He asked, "You said that all the citizens of Hill civilization were killed in battle, so what are you?"

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

But the answer seems self-evident.

Tang Xuan turned his attention to the neutron war star not far away.
