Unconsciously, a thousand years have passed since Xiao Yu embarked on the journey of the silver heart. In the past thousand years, the Shenzhou civilization has undergone almost earth-shaking changes.

The most important change is that the total number of warships held by Xiao Yu has reached 160 million, which has completely exceeded the number of warships that a sixth-level primary or intermediate civilization can have. And that number continues to increase. Of the 160 million ships, about 30 million were new ships made entirely of the flesh and blood of the Treant Beasts. These new spaceships will become the most core and elite Liliang in Xiao Yu's huge fleet.

It is estimated that by the time he reaches the Silver Heart, Xiao Yu's warship reserve will reach 300 million, the number of new warships will reach 50 million, and the number of planetary-class warships will reach 100. Although this combat power is not comparable to several high-end combat forces in the galaxy, such as the Guardian Sweeper, this combat power has the qualifications to attract their attention.

The tasks of planetary transformation and the construction of various energy bases, energy harvesting equipment, etc., have been completed. According to Xiao Yu's plan, a thousand planets have either become habitable planets, or tourist planets, or industrial planets. And those previously built habitable continent-class spaceships are still in service, and Xiao Yu has even built two new planetary-class habitation spaceships, which can be regarded as a complete solution to the problem of nowhere to live due to the increasing number of intelligent creatures.

Sapient beings are free to choose whether to live on planets or ships. Xiao Yu provided them with a complete internal transportation system in the small universe, and it was not troublesome to transfer between two different planets or spaceships. At the same time, Xiao Yu predicts that based on the growth rate of intelligent creatures at the moment, he will be at least in 5,000 years. There is no need for such construction.

The completion of various large-scale construction tasks has allowed Xiao Yu to recover a lot of computing power, allowing Xiao Yu to focus more on warship manufacturing and scientific and technological research and development. Under these circumstances, a well-developed two-dimensional weapon that could be used in real combat was finally developed. For this reason, Xiao Yu specially stopped his progress and chose a star system as the shooting range for his new weapon.

Under Xiao Yu's control, a continent-class spaceship equipped with two-dimensional weapons approached a rocky planet about the size of Mars, and then released energy-infused and encapsulated two-dimensional space fragments. Under the gaze of Xiao Yu and a group of scientists. Planets that have been invaded by two-dimensional space and have begun to fall from three-dimensional to two-dimensional have erupted with unimaginably huge amounts of energy, which is even comparable to the explosions of some stars. At this moment, the light emitted by this rocky planet. It has comprehensively exceeded the brightness of the stars around it.

After the energy burst was completed, Xiao Yu saw a two-dimensional planet. From a three-dimensional perspective. Xiao Yu saw all the internal and external structures of the planet at the same time. I also noticed that this two-dimensional space was constantly decreasing under the erosion of the three-dimensional universe.

Perhaps, in the future, the huge energy released by the fall of space to the lower dimensions will also become a way to obtain energy beyond the decay of elements and the fusion of antimatter. However, judging from the technological level of the sixth-level civilization. I don't see the possibility of mastering this source of energy. Perhaps, when I reach the level of a seventh-level civilization, I will be able to master this energy. Xiao Yu thought silently, "Maybe it's because of this way of energy source." Only the seventh-level civilization can not be restricted by the river system, and can freely shuttle back and forth between different river systems. ”

After mastering all the characteristics of the two-dimensional weapon through several different weapons, and after a series of improvements to it, Xiao Yu once again began the modification operation of the built Haode spaceship. This task is much simpler, and it doesn't require much computing power from Xiao Yu. On the contrary, it is the research and development of the second maintenance cover, which occupies a lot of Xiao Yu's computing power.

However, at this time, whether it is a two-dimensional weapon or a two-dimensional maintenance cover, or a Luoya round cup, and a space jishu, none of them is important. Because the thousand-year period has arrived, if there is no accident, Xiao Yu's companion ghost clan will soon wake up and become a fourth-level ghost clan.

A fourth-level ghost clan has an incomparably huge value, even if it is not from the value level, only from the emotional level, Xiao Yu also feels sincerely happy that this loyal comrade-in-arms who shares weal and woe with him can have today's achievements.

Everything was like Xiao Yu's jihuahaode, at an accurate point in time, from a corner of the small universe, Xiao Yu noticed this fluctuation. The difference is that this fluctuation is much smaller than the fluctuation before the associated ghost clan sleeps. If Xiao Yu hadn't made great technological progress during this time, Xiao Yu really wouldn't have been able to detect it.

"Ghosts! Have you become a fourth-level ghost? Xiao Yu released a message full of joy.

Xiao Yu was greeted with a deep sigh: "Yes, I have become a fourth-level ghost clan. The answer to that question, I finally knew at this moment. I see, I see. ”

The companion ghost clan once said that there was a problem that was bothering it, and if it understood this problem, it could become a fourth-level ghost clan. But when Xiao Yu asked, the associated ghost clan said that there was no way to express this question in words or words.

"You're now a fourth-level ghost clan, so, what the hell is this, can you tell me?" Xiao Yu asked with some curiosity.

"Well, I've organized the language to talk about this question, but I can't tell you the answer." "The question is, in short, what life is. I now have the answer, so I'm a fourth-level ghost. Unfortunately, I don't have the means to put my answers into words or words for the time being. ”

"That's it." Xiao Yu replied a little stupidly, "Then let's talk about this later." Ghost, how are you fighting now? In the near future, our Shenzhou civilization will encounter a major challenge, and your combat power will be crucial. ”

"My combat power ......" The companion ghost clan pondered for a moment and replied, "My current combat power is probably similar to the combat power of the tree clan alien beast at its peak. This is the combat power of a complete version of the fourth-level ghost clan. As for the challenges...... What are the challenges? ”

After the ghost clan entered a thousand-year slumber, Xiao Yu found the news that there were seventh-level civilization ruins in the direction of the silver heart, and all the major shili in the galaxy had already planned to get involved, so the ghost clan did not know about these things.

Xiao Yu told the companion ghost clan in detail, and the companion ghost clan laughed: "Very good, very good, then let's go." With me and the Ball of Death, and the 300 million powerful warships equipped with 2D weapons that we will have at that time, even if we can't achieve our ultimate goal, we will always have no problem escaping. In other words, I've been looking forward to the day when we can really stand in front of the Taihao Alliance, the Sweepers and the Guardians, and I've been looking forward to it for a long time. ”

"Okay, then let's wait for this day to come!" Xiao Yu also replied with a comfortable daxiao.

The two-dimensional weapon has been successfully developed, and the development of the two-dimensional maintenance cover is immediately on the agenda. There are still a thousand years to go, and Xiao Yu is not worried that during this time, he will not be able to research the technology he needs.

Five hundred years later, the Shiyan second maintenance cover was successfully developed, Xiao Yu loaded it on a spaceship model with a length of only one meter, and then took various offensive methods, Shiyan took various properties of the second maintenance cover, and at the same time continued to carry out various transformation actions on the second maintenance cover.

This is a critical jishu breakthrough, and with this breakthrough as a foundation, follow-up research is much easier. Another three hundred years passed, and Xiao Yu finally got the full version of the second maintenance cover technology. During this time, the two-dimensional weapon transformation of the original warship has been completed. After the technology of the second maintenance cover matured, Xiao Yu immediately began to carry out a new round of spacecraft transformation work.

From this moment on, Xiao Yu's spaceship not only has a mature two-dimensional weapon, but also a mature two-dimensional maintenance cover. At the same time, in the process of installing two-dimensional weapons and two-dimensional maintenance covers for these spaceships, Xiao Yu also adopted a large amount of information blockade, trying his best to improve the difficulty of the enemy civilization to analyze the technology from the spacecraft after it was captured.

Xiao Yu was sure that even if the Sweeper and Guardian Civilization captured their own spaceship, it would be impossible to analyze the two-dimensional weapon and two-dimensional maintenance cover technology from their own spaceship without consuming a lot of manpower, material and social resources, and for a long time.

The two hundred years of Zuihou are the end of Xiao Yu's various construction tasks. In the past two hundred years, Xiao Yu has fully completed various construction tasks, the spaceship reserve has reached the expected 300 million, and 50 million new warships have also been completed.

The combat power of the Shenzhou civilization has reached its peak. Since Xiao Yu's birth, the Shenzhou civilization has never been as powerful as it is now.

By observing the increasing density of stars around him, as well as the various extreme stars that began to appear in frequency and increasing significantly, as well as the supermassive black hole that became more and more obvious in front of him, Xiao Yu knew that he had reached the galactic heart realm.

"The ruins of the seventh-level civilization in the mechanical direction are about to open, and the carnival feast of all the powerful beings in the galaxy is about to begin. Come on, our Shenzhou civilization is ready......" (To be continued......
