Although the Dragon Star is a satellite, its size is not inferior to that of the Earth, with lofty mountains, vast forests, rivers and dense forests!

In the vast dense forest, there are a large number of ferocious creatures: first-level creatures are everywhere, second-level creatures are innumerable, third-level creatures are innumerable, and there are more than 200,000 fourth-level dragons.

And among all the creatures, the 19 dragons scattered all over the planet are like lighthouses in the dark, and the lice on the bald heads are very conspicuous.

Their vitality is too strong, like the white cranes in a flock of chickens, the detector can detect their existence by a slight sweep, and the barbarian tower locks the location of the Dragon King, and controls the flying saucer to shoot over!

After 47 seconds, the flying saucer arrives at the location of the Dragon King!

Arctic Ice Field!

The place where the Dragon King dwells is in an icy lake on the Arctic ice field!

This lake is an ice lake, surrounded and underneath is full of cold ice, and the ice lake stands on the ice, about 50 kilometers in diameter and about 40 kilometers deep.

The slender body of the Dragon King lay quietly at the bottom of the lake, his eyes closed, and the water around him swayed slightly with his breathing, which seemed to be regular!

"Senpai!"

Suddenly, there was a loud cry on the surface of the lake, which directly woke up the Dragon King, who opened its huge eyes and saw the lake through the water dozens of kilometers deep.

"It's this kid, what is he doing here?"

Puzzled in his heart, the Dragon King's lips moved slightly, and he let out a low humming sound: "What is the matter?" ”

The sound is like rolling thunder, directly penetrating the lake and spreading to the lake's surface!

"Senior, something is wrong, I urgently need your help!" Xue Yu roared loudly.

"What's the matter, so panicked?" The Dragon King's eyelids jumped slightly.

Xue Yan hurriedly said: "I don't have time to explain now, you hurry up and go with us, in short, it is a big matter that threatens the Dragon Star!" ”

"Wow"

As soon as Xue Yu's words were finished, there was a slight sound of water breaking, and in the next moment, a behemoth appeared in front of him, which turned out to be the Dragon King.

"A danger that threatens the Dragonstar? I hope you don't lie to me, otherwise" The Dragon King stared at Xue Yu coldly: "Lead the way ahead!" ”

"Let's go!"

Xue Yan was a little shocked that the Dragon King believed his words so much, but the matter was urgent, and he couldn't say anything more, so he directly ordered the boat to start, and the flying saucer flew out with a "whoosh", and disappeared without a trace in the blink of an eye.

The Dragon King stood in place, staring at the disappearing flying saucer, and did not see it make any movements, its figure flashed, and it also disappeared, in terms of speed, it was more weird and faster than the flying saucer.

Another 47 seconds later, the flying saucer returned to the "snail" spaceship, the flying saucer had just arrived on the front foot, and the back foot of the dragon king came one after another, Xue Yu was not shocked, in his opinion, as the former Ying Long, the speed of the dragon king was much faster than that of the flying saucer.

"Senior, hurry up and destroy this spaceship!" Xue Yu flashed outside the flying saucer and pointed to the snail shell spaceship below and urged.

"What the hell are you doing, boy?"

The Dragon King stared at the spaceship, and found that this spaceship was ordinary, like a dead thing, no matter how good Rao is temper, he couldn't help but be a little angry, it felt that it had been tricked by Xue Xu.

"Senior, please believe me, this spaceship is really in danger!" Xue Yu said.

"Humph! If you dare to lie to me"

The Dragon King snorted coldly, his eyes glared at the spaceship, and in the next second, there was a "stab" sound, and the snail shell suddenly broke in half from the middle, and then, with an unpleasant stabbing sound, the entire spaceship was like a fruit chopped by a random knife, shattered into a pulp!

"Scattered"

The Dragon King let out a low shout, and it had turned into a sloppy spaceship, and the sound of "buzz" turned into powder!

Xue Yu was dumbfounded, the Dragon King didn't do anything, just stared at his eyes a few times, and the sturdy sixth-level spaceship made of eighth-level alloy turned into powder.

This kind of strength is simply unfathomable!

"Is this what was once a seventh-level lifeform?" Xue Jun muttered to himself, shocked again and again: "It's really powerful!" ”

"Boy, what about the danger you are talking about?"

After the spaceship was torn apart, the Dragon King didn't see the danger from beginning to end, and couldn't help but feel that he had been tricked, his eyes were surging with anger, and the killing intent around him involuntarily emanated.

"Senior" Xue Jun opened his mouth, and was about to explain, but he didn't think that the Dragon King suddenly stared at the spaceship that had turned into powder, and a glint flashed in his eyes.

In the next moment, a silver "water droplet" rose from the powder!

Drop?

No!

It's not a drop of water!

Rather, it is a pearl that shimmers with a silver light, and its volume is very small and less than three millimeters in diameter, so it can be said that the small one can no longer be very inconspicuous.

But the Dragon King stared at the bead, and the essence in his eyes became more and more vigorous.

"What is this?" Seeing that the Dragon King suddenly shifted his attention, Xue Ji couldn't help but be puzzled, followed and looked over, naturally seeing this silver bead, he was puzzled.

"This material"

The tower immediately released gravitational waves and began to scan the bead, and after a moment, it directly exclaimed, "Oh my God! How can there be such a thing here? ”

Hearing the exclamation of the Barbarian Tower, Xue Jun was even more curious, and even asked, "Manta, what is this?" ”

"This is the Neutron Battlestar!" The Brute Tower whispered.

"Neutron Battlestar? What is this? ”

Faced with this new term, Xue Yu was a little incomprehensible.

"The Neutron Battle Star is the most famous weapon in the universe!"

The Brute Tower explained in a low voice, "Do you know about the Neutron Star? ”

"I've heard of it!"

What is a neutron star?

It is the most extreme object in the universe other than a black hole, and it is one of the few possible endpoints of a supernova explosion at the end of a star's evolution.

To put it simply, a star with a mass of less than 8 suns will become a white dwarf after death!

A star with a mass of 82 or 30 times the mass of the Sun will evolve into a neutron star after death!

And the mass of the star is so great that after more than 30 suns, once it dies, it will evolve into a black hole!

The biggest feature of neutron stars is their high density and high mass!

Its density is as high as 810 grams per cubic centimeter to the 13th power and 210 grams to the 15th power gram, which is a massive mass of 802 billion tons per cubic centimeter!

This density, which is the density of the nucleus, is a hundred trillion times the density of water.

If the Earth were compressed like this, the diameter of the Earth would be only 22 meters!

In fact, the density of neutron stars is so great that the mass of a neutron star with a radius of 10 kilometers is comparable to the mass of the Sun.

Support, support, support!
