All the puzzles about the first test have been solved, and the huge fleet is cautiously approaching the dwarf planet under Xiao Yu's control.

Dwarf planets are a general term for a class of stars, such as Pluto, Xena, Sedna and other stars in the solar system, all of which belong to dwarf planets, also called pluto-like bodies. From this point of view, Pluto is very unqualified as the ninth planet, and in the Kuiper Belt, Xena is larger than Pluto, and if it is the ninth planet, it should be Xena instead of Pluto.

So astronomers in the age of Earth downgraded Pluto from a large planet to a dwarf planet. These stars can reach a spherical appearance under hydrostatic equilibrium, but their gravitational pull is not strong enough to empty the rest of the bodies above their orbit, and they are considered mutilated planets. In fact, the Moon is also a dwarf planet if it does not revolve around the Earth but around the Sun. In addition to the Moon, several moons of gas planets such as Jupiter and Saturn also qualify for this.

At this moment, in front of Xiao Yu is such a star. Sufficient material analysis data indicate that it is presumably composed of iron and nickel, and that its main composition is similar to that of Earth.

During the voyage, Xiao Yu was not idle along the way. The Torol civilization was exterminated in the war with the Sweeper civilization, and this is the remnant of the Torol civilization, which means that you can find a lot of data about the Sweeper's combat power and combat methods here.

This was the first informal encounter with the Sweeper civilization. In the past 10,000 years, Xiao Yu has only heard of the Cleaner civilization and has not seen its people, but now, he has finally really come into contact with a little Cleaner civilization.

Hundreds of thousands of years ago, the powerful sweeper civilization was also like Xiao Yu. Been to this place. The difference is that at that time, this small universe was still part of the larger universe, and at that time, it was the only tens of thousands of powerful warships left in the Torol civilization that greeted the Sweeper civilization, not the debris everywhere like now.

The strength of the Sweeper's civilization is on full display. Even after hundreds of thousands of years, the smell of destruction they left behind still shocked Xiao Yu.

Like a piece of battleship in front of you. It was about a dozen meters in diameter, and it looked like it had been torn from a spaceship. Inside, you can also see some elaborate instrumentation mechanisms. These instruments are also incomplete. As a result, Xiao Yu had no way to analyze these instruments at all. However, there is a phenomenon that has aroused Xiao Yu's great interest.

That is, the section of this fragment is too flat. Generally speaking, no matter what something is cut off, there will always be traces of it. By analyzing the different cross-sectional data, it is possible to roughly determine what it is cut off. This is true even for things that have been cut off by disintegrating rays and laser rays. The laser leaves traces of high temperature in the cross-section. The disintegration of matter will leave a special kind of radiation on the cross-section. And it cannot be eliminated.

However, on the section of this fragment, Xiao Yu could not find any traces for analysis, and its section showed a standard straight line. Although this straight line has been slightly out of shape after the invasion of time, it has been reduced and analyzed. Xiao Yu can still confirm that when this section was just manufactured, its neatness even reached the level of hadrons.

Other words. The atomic structure of these substances has been cut off at once, and even if you look at them from the atomic structure, they are extremely flat.

Such a degree of smoothness is not inferior to the teardrop-shaped detector that Xiao Yu has ever seen.

This fragment, Xiao Yu who saw it was secretly shocked in his heart. Now Xiao Yu has a feeling described in martial arts novels, a certain hero casually cut off a branch and handed it to another certain hero to watch, and a certain hero saw the magic from the broken branch, so he bowed down.

The current Xiao Yu was shocked by this branch.

"This should be a space weapon, the fracture of space will cause all the matter inside them to break with it, even the atomic structure will not be spared, all of them will be broken in two. Come to think of it, the weapon called Spatial Splitting is also the same way of killing. Xiao Yu thought secretly, looking forward to it more and more.

In fact, there are many such fragments in this galaxy, and the number is almost endless. Xiao Yu didn't intend to let go of these things, so Xiao Yu sent a huge number of miniature spaceships and micro-robots, intending to look here to see if there were any complete instruments that could be recycled and used, and it would be great if he could peek into the technology of the sixth-level civilization.

But the result disappointed Xiao Yu. All the instruments that the robot saw were completely destroyed, and there was no possibility of repair. Naturally, Xiao Yu couldn't peek into the technological level of the sixth-level civilization from them.

"It's really worthy of being called a sweeper, and it was so thoroughly cleaned that nothing of value was left for me. Could it be that this is why you have earned the title of Sweeper Civilization? Xiao Yu thought secretly, and he still slandered himself in his heart.

After thinking about it, Xiao Yu gave up the idea of getting the treasure from the garbage heap, and instead put all his mind and attention on the dwarf planet that was getting closer and closer.

At the moment, there are less than 300 million kilometers left. The white dwarf star was much brighter at this distance, probably the brightness of a dusk moon on a cloudy day, and it looked unusually beautiful.

"This dwarf planet is the lair of Intelligence-One...... Don't know what kind of test it has in store for me? ”

The distance is still slowly approaching. When the distance was shortened to 30 million kilometers, Xiao Yu received a message from Smart One.

"Good, you've passed the first test." "The great Torol civilization has left you with three tests, and next, the second test will take place. ”

"The great Torol civilization has asked me to build a fleet after all of them have died, in order to test your comprehensive combat strength...... Of course, they are not the fleets of the sixth-level civilization, they are just some warships of the fourth-level civilization with a scientific and technological level, and the number is not large, about 30,000. The Torol civilization has asked me to convey to you that if you destroy these fleets, you will pass the second test. If it cannot be destroyed and the test fails, you will remain here forever. ”

Just as Xiao Yu was watching, one after another spaceships flew up from the dwarf planet and quickly lined up in front of him.

"Is it just a fleet of fourth-level civilizations?" Xiao Yu breathed a sigh of relief in his heart, "This is not difficult for me at all. They haven't mastered tachyon and negative matter-related technologies, but they have a big gap with me in terms of defense, attack, and detection. It seems that the Sapient One may not have evolved its own independent mind, and it is still acting according to the instructions left behind by the Torol civilization. If that's the case, then there's nothing to worry about. ”

Although Xiao Yu has not miniaturized the negative matter cannon to equip it on his spaceship, and truly turned science and technology into his own combat power, the progress of science and technology is comprehensive, and Xiao Yu's combat power is still not comparable to that of a fourth-level civilization.

For example, the tachyon shield, a fourth-level civilization does not have this kind of technology. For example, antimatter engines, antimatter bombs, such as faster-than-light reconnaissance - the battlefield reconnaissance method adopted by the fourth-level civilization is still by launching a large number of probes into the battlefield, and then transmitting the relevant information back to the commander through over-distance communication, so as to remove the delay of radio transmission. However, there is a disadvantage to this, that is, on the battlefield, the survivability of the probe is not very strong, and it is easy to be destroyed.

This point has been deeply experienced in several large-scale space wars in the past. It's just that after mastering the tachyon-related technology, Xiao Yu has never worried about these things again. The faster-than-light probe can be directly equipped on the spacecraft to obtain battlefield information in real time, which not only greatly improves reliability, but also makes it much more convenient.

In addition to these, Xiao Yu also has the most powerful defensive tools, obtained from the four maintenance shields of the Taihao civilization. The four-level maintenance cover is a real sixth-level civilization technology, and in Xiao Yu's speculation, even ordinary sixth-level civilizations may not necessarily have it. The combination of various factors made Xiao Yu completely indifferent to these 30,000 fourth-level civilization technology level spaceships, and even some contempt.

"Do as you are told, Smart One." Xiao Yu sent out his own message: "We will do our best to prove our ability and prove that we will not disgrace Torol's prestige." ”

Three million spaceships were suspended in space, the Homeland spacecraft did not move, the more than one million spacecraft guarding the Homeland spacecraft did not move, all the national and provincial spaceships did not move, only a dozen city-level spaceships, carrying about 100,000 other small and medium-sized spaceships separated from the large army and sailed towards the poor 30,000 spaceships.

In Xiao Yu's visit, among the 30,000 spaceships, the largest one barely reached the standard of his own city-level spaceships, and there were only two, and there were not many county-level spaceships. Sending more than a dozen city-level spaceship formations was already the result of Xiao Yu's repeated warnings that he should not underestimate the enemy.

The distance between the two fleets is getting shorter and shorter, and the war is about to begin.

At this moment, at the edge of this star system, in the dark depths of the universe, the fourth-level alien beast curled up its body, motionless.

There was an imperceptible channel of information running between its mind and the dwarf planet, and a lot of information was rushing down this channel.

"Is that so? I understand. I'll work with you. (To be continued......)
