In the more than 30 years since the Neutron Battle Star disappeared, Xiao Yu didn't know what had happened. But Xiao Yu knew that the conflict that occurred during this period of time must have been extremely intense, even beyond his imagination.

It is not an exaggeration to say that this is under the seventh-level civilization, and it is not an exaggeration to say that this is the most high-end war.

On the one hand, it is the Taihao civilization that failed to attack the seventh-level civilization, but has a semi-four-dimensional structure, and on the other hand, it is the cleaner civilization that has mastered the seventh-level civilization creation and the neutron battle star.

The duel between these two powerful civilizations is like the master tricks described in some martial arts novels, if you look at it from the outside, you can only see two masters palms against palms, motionless, at most a little steam on the head, plain, but the danger in the shadows will only be known by those who have personally participated in the battle.

The battle between Taihao and Neutron Battlestar is such a process. Xiao Yu only saw that the neutron battle star had disappeared for more than thirty years, the Taihao civilization had been quiet for more than thirty years, and the rest of Xiao Yu didn't know anything. Xiao Yu only knew that after more than 30 years, the neutron battle star reappeared, and Taihao was torn apart.

"Taihao is dead." Seeing this scene, Xiao Yu thought a little sadly.

The environment of the open star cluster in the middle of the war at this moment, Xiao Yu can probably guess it. In this battlefield, there must be a lot of hot material from the bursting stars, and all kinds of extremely intense rays are sweeping across the entire open star cluster, and the environment there must be extremely harsh.

In that environment, even the most powerful warship in Xiao Yu's hands, the Hebei, was not sure that it would survive.

"This level of war is really not something I can touch." Xiao Yu sighed, "It seems that Taihao threw me away in advance." The decision not to get too close to the battlefield was the right one. Otherwise, I would have died with Taihao. ”

Taihao's death brought Xiao Yu a short period of distraction. After coming back to his senses, Xiao Yu saw that the countless points of light that were entangled with the Sweeper Civilization seemed to be panicked at the moment when Taihao died. As soon as the neutron battle star appeared, it fiercely rushed into the densest place of light. This pile of light spots is like a pile of fireflies and insects that have been hit by something, and they scatter violently with a bang.

The death of Taihao Civilization represents this war, and the victory and defeat are truly divided.

In the midst of the scattered dots of light. The most conspicuous is a spot of light that takes on a pale orange color. This point of light seems to be the most powerful. At the moment when the Neutron Battlestar appeared. It instantly shifted a distance of several light-years, dodged the most violent blow of the neutron warstar, and then disappeared in an instant, disappearing from the open star cluster, and did not know how to escape.

The rest of the points of light were not so lucky. Under the chase of the Neutron Warstar, and the rest of the points of light belonging to the Sweeper civilization. These points of light can't even escape, but can only be extinguished one by one by the Sweeper civilization.

In the end, there was not one out of a hundred points of light that escaped.

This huge war. The curtain has finally come to an end.

This war gave Xiao Yu a clearer understanding of the strength of the Sweeper civilization.

"I didn't expect that the Guardian civilization would be able to escape in such a situation. It seems that during these tens of millions of years, the Guardian civilization may have focused most of its energy on escaping and hiding its tracks. According to Luca's scientists, tens of millions of years ago, when the Sweeper civilization did not have a neutron battle star, the Guardian civilization was still on par with the Sweeper, but now, there is such a huge gap in strength. Neutron Battlestar, Neutron Battlestar...... It's really so powerful......"

"In this great event, there is no doubt that the Sweeper civilization has reaped the greatest benefits. It has wiped out the Taihao civilization and eliminated hundreds of fourth- and fifth-level civilizations, I don't know how much benefit this will bring to them, I don't know if the luck brought by destroying so many powerful existences can make them break through to the level of seventh-level civilization......"

"I hope not. If they break through to the level of seventh-level civilization, then the rest of the civilizations in the galaxy will suffer. However, it is not good to say, maybe the seventh-level civilization can break through the limitations of the river system and start a distant journey calculated in millions of light-years, tens of millions of light-years, and lose interest in low-level civilizations from then on. ”

So far, what Xiao Yu has seen and heard is still all limited to the galaxy. The Great Magellanic Galaxy is just a satellite system of the Milky Way, and the relationship between the two is similar to the relationship between the Earth and the Moon, so the Taihao civilization from the Great Magellanic Galaxy still belongs to the Milky Way in a strict sense.

The extragalactic galaxy, like the seventh-level civilization, is an unknowable existence for Xiao Yu. Xiao Yu guessed that perhaps after reaching the seventh-level civilization, he would have the ability to sail the river system.

In the midst of speculation, Xiao Yu manipulated the fleet and began to accelerate again, galloping towards the predetermined target.

In the decades since observing the war, the number of Lucca has increased again, and at the same time, there have been some breakthroughs in biotechnology, and the average life expectancy of Lucca has exceeded the millennium mark. As a result, the number of scientists who can work for Xiao Yu has reached 3,000.

These 3,000 scientists, together with Xiao Yu, are busy researching science and technology all the time. However, in the past few decades, Xiao Yu's science and technology have not made a breakthrough.

"Sure enough, as I imagined, when science and technology have advanced to a certain extent, it is no longer possible for a genius scientist to promote its progress independently. If my technology wants to improve again, it has to be built up over time. Looking at the brighter star in front of him, Xiao Yu sighed in his heart.

During the long journey, Xiao Yu's fleet had shrunk to less than 70,000 ships. But fortunately, at this moment, Xiao Yu is no longer far away from his destination, and there is probably only one year left for the voyage.

Xiao Yu had already transformed several faster-than-light village-level spaceships in advance, carrying some instruments to start exploring this star system in advance. Xiao Yu was greatly encouraged by the results of the detection.

The data shows that although the star has entered middle and old age, it is still in a stable stage by and large, and it has a huge gas planet, which is four to five times the mass of Jupiter. On top of that, the gaseous planet is home to hundreds of rocky moons. These satellites will provide Xiao Yu with an endless supply of building materials.

Therefore, while still on the journey, Xiao Yu began to make intense preparations.

Xiao Yu is already familiar with how to transform a star system and how to maximize access to resources, and has accumulated a lot of relevant experience in the four star systems of Tianyuan and the Aquila Nebula. In the ten years since arriving at this star, Xiao Yu has the confidence to rebuild his industrial system.

In the midst of busy preparations, a year later, Xiao Yu arrived around the star. Looking at the place where he had to stay for at least a hundred years, Xiao Yu's heart was full of admiration.

"What a paradise place." Xiao Yu admired.

Stable stars, huge gas planets, and hundreds of moons, all of these are full of strange temptations for Xiao Yu.

"This star...... Let's call you the Star of Hope, this planet, simply call it Hope One. The satellites orbiting Hope 1 are sorted alphabetically by size. ”

After slowing down, Xiao Yu's fleet smoothly entered the orbit orbiting Hope One. After that, the first thing Xiao Yu did was to determine the naming rules of these stars and notify the Lucca scientists. In the future, Xiao Yu and Luca's scientists will follow this set of naming conventions to communicate.

After determining this, Xiao Yu began a huge, messy, but well-organized planetary system transformation project. Xiao Yu first sent a large number of satellites to carry out detailed exploration work on hundreds of satellites of Hope 1, and determined their elemental composition, size, mass, utilization value and other related data.

With this data, the next step is much easier. On the spaceship, Xiao Yu had already prepared a huge team of construction robots, and these robots were sent to different satellites according to their different functional classifications to carry out their own work.

They first carried out the construction of the collection bases, which will be responsible for the supply of raw materials for all Xiao Yu's future construction projects. After the base is collected, there is the preliminary forge factory.

These factories will carry out the initial processing of the minerals mined at the mining base for later use.

After the forging factory, there will be a robot casting factory and a various parts production plant. Because of the limitation of the tonnage and volume of the spaceship, it is impossible for Xiao Yu's spaceship to carry too many robots, so the construction of a robot casting factory is also very necessary. The parts factory includes a variety of precision instrument foundries.

In addition to ground construction projects, Xiao Yu also built thousands of huge space docks in space. These spaceyards will be responsible for the construction of new spaceships, as well as the faster-than-light retrofit of old spaceships.

Under the control of Xiao Yu's huge computing power, all complicated things are carried out in an orderly manner.

The robot foundry factory at the ground base has become the heart of Xiao Yu's entire construction project, and these hearts are exporting a large amount of fresh labor every moment to supplement various organs. The collection base is constantly exporting nutrients and supplying them to various factories.

The era of vigorous construction has once again opened. (To be continued......)
