Under Xiao Yu's coordination, everything was carried out in an orderly manner. It's been five years since I came to this planet. In the past five years, Xiao Yu's various infrastructures have been completed, and a total of thousands of large-scale gathering bases have been built, which are producing huge amounts of minerals every moment for various research and construction of shiyan instruments.

"The predecessors of the ghost clan said that I have eighty years of development, but this time is a combination of scientific and technological research and application. There's always a buffer period when a new jishu is developed until I make the finished product. So, my time is not actually eighty years, but ...... Only fifty years at most. In 50 years, I will put together all the new jishu that I have developed and complete all the construction tasks in 30 years. ”

"When the time comes, I will turn this star system into the grave of the fleet of the Morlian civilization." Xiao Yu secretly made up his mind.

Yes, Xiao Yu is not ready to leave here to fight against the Molian civilization. Xiao Yu can completely use the safe development time of these decades to operate this star system into a complete interstellar fortress, and then go to fight a defensive battle with the Molian civilization and destroy the other party in defense.

In defensive warfare, the most effective and powerful weapon is undoubtedly the negative matter cannon. In Xiao Yu's current theoretical system, there is no effective way to defend the negative matter cannon. In the face of negative matter cannons, there is only one way to defend against them, and that is to rely on the same amount of energy or mass to neutralize the tachyon torrent. This is the same for either a fifth-level civilization or a sixth-level civilization.

Through the construction of the first large negative matter cannon, Xiao Yu mastered a lot of relevant knowledge, and after the construction of the ground base, Xiao Yu immediately started the construction of the new negative matter cannon. The site where this negative matter cannon was built was set in the orbit of this planet. Because the relevant technology is not perfect at present. Therefore, this negative matter cannon is still only experimental in nature and has no practical significance.

The length of the previous negative matter cannon was five kilometers, but the muzzle diameter was only two hundred meters, and its attack power was nothing compared to its huge size. And it was also unstable, Xiao Yu only did one shot shiyan, and it burned out completely.

The construction of the last negative material cannon exposed a number of jishu problems. Now, these jishu problems have been solved one by one by Xiao Yu and scientists of various races, and the negative matter cannon built this time is also five kilometers long. But the muzzle diameter reached the level of five hundred meters. After it was built, its power was increased tenfold.

So far, there are more than thirty large space bases orbiting the planet, all of which are integrated in nature. They can even complete the construction of various instruments on their own. In this case, some precision parts are simply made in space. It was then transported to the nearest place where the negative material cannon was built. Xiao Yu manipulated the robot to assemble.

On this planet with constant plate collisions, strong earthquakes, volcanic eruptions, and extremely active geological activities, Xiao Yu's spaceship is busy shuttling back and forth, transporting endless construction materials from the ground to space. In response, one shiyan data after another was transmitted back to the ground, and the massive negative matter cannon was slowly increasing in size......

At this time, another obstacle was placed in front of Xiao Yu. Xiao Yu felt it. My own computing power is gradually insufficient.

Although a large number of automated equipment has been used to manipulate the instruments, Xiao Yu no longer touches the calculations at the bottom of the machine, but only controls them in the overall situation, but even so, the computing power they require is still an astronomical amount.

Xiao Yu has maintained the current quantum computer architecture for many years, and after so many years of development, the computing power of the main computer has slowly fallen behind.

"Is it to allocate computing power and develop a computer with a completely new architecture, or is it to do some tinkering on top of the current architecture? In the case of the former, it is estimated that it will take me at least 30 years to allocate at least 10% of my computing power, but I can increase my computing power by at least 30 times. In the case of the latter, the finished product can be built in five years, and the computing power can be tripled at the current stage...... Well, it's too busy right now, so let's put the new architecture in the future, and just fix the current computer architecture for the time being. Three times the computing power, which is enough for the time being. ”

After thinking about it for a while, Xiao Yu made a decision.

"My junior, I am amazed by your development potential and execution ability. I see in you the shadow of the Lord civilization, and at your present stage, it is as crazy and full of spirit as you. It's just a pity that it still failed to defeat the Neutron Battlestar in the end. ”

While Xiao Yu was busy with work, the message of the ghost clan was delivered.

Xiao Yu responded: "Senior, I am honored to be protected by you and to have this precious decades of development time. The pressure of survival was always pressing on me, so I had to go crazy and have to be energetic. By the way, how are you doing now? ”

"My situation...... It's the same old way. My body is aging, and the huge energy from the stars is almost unable to suppress the negative matter raging in my body, and when the positive energy can no longer suppress the negative energy, it is when I die. ”

Hearing this, Xiao Yu's heart moved.

What kind of existence the ghost clan is, Xiao Yu has not been clear until now.

"Can you tell me what state the Ghost Clan is in? Will the Weishenme Ghost Clan have such a strong combat power? ”

"Spectres......" it groaned for a moment, and continued, "You may have heard of the Spectre Clan's grading method. The Spectre Race's abilities are measured in a completely different way than the rest of the races. The ghost clan that your people turned into is probably at the second-level level now, and I'm a fourth-level ghost clan. ”

Xiao Yu recalled the scene when he fought with Lucca's civilization fleet. When the Ghost Clan first appeared, the commander of Luka's fleet seemed to have said something like "Second Rank Ghost Clan".

"The existence of the ghost clan is not logical, at least, with the scientific and technological strength of the sixth-level civilization, it is not possible to explain the ghost clan for the time being. Even I don't know what state I am. My main civilization once captured a sixth-level primary technological civilization, and they analyzed me in detail, do you know what the conclusion is? ”

The Ghost Clan's tone carried a hint of ridicule in it, and he continued: "The analysis results of this sixth-level civilization show that I do not exist in this universe. Yes, you heard it right, my total mass is zero, total energy is zero, everything is zero. In other words, there is no such thing as a ghost race in this universe - since the total mass and total energy are zero, how can it be said that a thing exists? ”

Hearing these words, Xiao Yu had a strange feeling in his heart.

Does something that has no mass, no energy, exist in this universe? At least Xiao Yu has not been found at this stage. Even the photon, although it does not have a resting mass, is undoubtedly carrying energy. Although the total mass and total energy of negative matter are negative, they do not exist stably in this universe.

At the end of the day, no matter whether the total energy and total mass are negative or not, they always have a meaning to exist. However, a thing with zero total mass and total energy, like the legendary dragon that exists in the house, cannot be seen, touched, or detected by any means, and it cannot have any effect on reality - in that case, it is better to simply assume that it does not exist.

"But you're real, aren't you?" Xiao Yu cautiously asked, "How can a thing with zero total mass and total energy have its own independent consciousness and such a strong combat power?" ”

"I don't know." The Ghost Clan replied, "This again involves the question of the classification of the Ghost Clan, and the Ghost Clan is divided according to the matter they possess. The first-level ghost clan is the ghost clan that only masters positive matter, the second-level ghost clan masters the positive matter and also masters antimatter, and the third-level ghost clan has more dark matter. Every time one more substance is mastered, the combat power of the ghost clan will increase a lot, until the fourth-level ghost clan masters all four substances. ”

"The total energy and total mass of the first three levels of the ghost clan are positive, only the fourth-level ghost clan that has mastered negative matter has a total mass of zero, but it is also the fourth-level ghost clan that is the most powerful."

"In other words, as a whole, the total amount of positive and negative matter in my body is equal, the two cancel each other out, and I don't exhibit any mass or any energy in the eyes of the outside world. But I do exist, I can cling to the stars, I can draw the energy of the stars, and I can travel through the universe and slaughter other civilizations at will. My existence is illogical, and at least the sixth-level civilization cannot explain my existence. ”

"Illogical?" Xiao Yu muttered to himself, feeling as if his mind had entered a dead end, and he couldn't turn around.

Xiao Yu has never been able to accept that a thing with zero total mass and total energy can be so powerful?

"This is the secret of the Ghost Clan's own construction, and if you study this issue thoroughly, you may be able to use this principle to develop more powerful weapons to defeat the Neutron Battlestar."

"Defeat the Neutron Fighting Star?" When he heard this, Xiao Yu's head instantly rolled into waves. (To be continued......)
