"Although I no longer exist in this universe, I am still very relieved to see that you have finally gained the capital to fight against the Sweeper civilization. Now, I'm going to tell you what I felt and some of my experiences when I fought against the Sweepers......"

"That's right, the Neutron Battlestar does possess some kind of soul attack ability, and it is precisely because of this ability that I will be killed by it. It also possessed some sort of wide-area attack weapon that seemed to be based on spatial energy, and in the middle of the battle, it was because of this large-area attack that the forces involved in the siege of the Sweeper civilization suffered serious losses. I don't have a good way to deal with this kind of wide-area attack weapon, and I can only rely on you to resist it with your own warship. Also, the Neutron Battlestar has a high-dimensional attack ability. And unfortunately, I don't have a very good way to deal with this high-dimensional attack ability. And as for the soul attack ability...... I've found some kind of limited coping. ”

"Before I died, I finally found a way to fully promote to a four-dimensional creature, if I was given enough time, I could completely become a full four-dimensional creature, that is, a seventh-level alien beast, and enter another new stage, a new world. It's a pity that I don't have time, so I can only put these feelings of mine on the four maintenance covers...... That's right, the four maintenance shields can resist high-dimensional attacks and soul attacks to some extent, and you need to stack many four maintenance shields on top of each other - the more they are, the stronger the protection ability, and completely envelop your hiding place, this kind of attack based on the source of life will not affect you. ”

"The following are some of my thoughts on high-dimensional attacks, and I hope you can use these things to find a way to counter the high-dimensional attack capabilities of the Neutron Battlestar......"

Xiao Yu listened quietly and did not make any reply. Because Xiao Yu knew that this was just a message left by the semi-four-dimensional Taihao before he died. It is dead, completely out of the universe.

"Is that so...... Well, hopefully you're right. Xiao Yu muttered to himself, "I hope the method you said can really fight against the soul attack." Not...... I have about 23,000 or so of the Four Shields left, so let's split them into two parts, one on the Sun spacecraft and one on the MSI corpse, to protect the ghosts. The ghost will provide enough energy to keep the quadruple dome running. It's just that in this way, in the high-intensity battle, the time for the ghost to manipulate MSI's corpse will be shortened again......"

"In the message left by the semi-four-dimensional Taihao, the kind of large-scale attack that originated from some kind of spatial energy should be the space burst. There is really no good way to resist this kind of weapon, and you can only rely on warships to resist hard. But I think about it with my current battleship performance. Ships of the national level and above. It's not a problem to resist this kind of attack. ”

"I hope you're right, because I have no idea about the soul, the so-called origin of life, and I can't study it at all. Hopefully, this approach will work...... Well, this problem should be solved, but what about high-dimensional attacks? ”

Xiao Yu is now in the spaceship. Equipped with four and two maintenance covers, as well as the rest of the various guards, but one thing is undoubted, these guards. None of them have the ability to resist attacks from the fourth dimension. Just like a closed circle on paper, no two-dimensional creature can break through the lines of the circle to reach the inside, but a three-dimensional creature can easily enter the inside of the circle through a higher dimension, and the same is true for four-dimensional beings for three-dimensional.

This is the end of the message of the semi-four-dimensional Taihao. The last vestiges of it are gone. And Xiao Yu, while continuing to carry out large-scale construction tasks, also began to think about how to deal with the attack method of high-dimensional attacks.

Time passed little by little, and in the blink of an eye, half of the time had passed since the thousand-year covenant. And Xiao Yu's warship reserve has finally reached 10 billion. About 60 percent of the interstellar defense system has been completed, and the remaining 40 percent will be completed in the next time. The Taihao Alliance has been staying next to Xiao Yu, and during this time, the companion ghost clan has been manipulating MSI's corpse to fight or cooperate with the Taihao Alliance every day. Because of Xiao Yu's support, a large number of rare materials can be obtained at any time, and the injury of the alien beast Taihao has recovered a lot. It's just that after recovery, the personality of the alien beast Taihao seems to have changed a little, and he is no longer so irritable and has begun to be silent. I don't know if it's because I've been scared or because I've been affected by other life factors. Xiao Yu didn't pay too much attention to it.

Because of the existence of the seventh-level barrier, Xiao Yu's scientific and technological progress has completely stagnated. At present, the possible scientific and technological breakthroughs are found from the cubes obtained from the seventh-level civilization in the mechanical direction, the scientific and technological materials left by the seventh-level civilization in the microscopic direction, and the four-dimensional jumping technology left by the unknown seventh-level civilization. But this is a very complex and huge project, even with Xiao Yu's scientific research strength, it will take a lot of time to analyze these things to pile up before they can be completed.

Therefore, Xiao Yu didn't have the luxury of expecting that he would be able to analyze these technologies before the Sweeper Civilization attacked. Xiao Yu just regarded these things as a clue to enter the seventh-level civilization, and after waiting for himself to win the war with the Cleaner civilization, after he had no worries, he could use a lot of time and distractions to analyze these technologies, and finally enter the seventh-level civilization.

There has been no progress in science and technology, and the entire upper echelons of the Shenzhou civilization have fallen into a state of decadence. Xiao Yu knew that this state was dangerous. If an ordinary sixth-level civilization encounters this state and loses the ability to move on, the outstanding people in the civilization will invest their energy and desires in other aspects, such as war, such as internal friction. This is a very bad state.

This state continued for a while, until Xiao Yu received a message again.

This message was very unexpected by Xiao Yu, because Xiao Yu originally thought that he would never have the possibility of dealing with this civilization again in this life, and even if it was possible, it would be a long time later.

It was the Guardian Civilization who sent this message.

"Shenzhou Civilization, hello, we are the new leading group of the Guardian Civilization. Contacting you this time is a decision made after careful discussion and consideration within our civilization. Yes, that's right, we're going to help you. ”

"To be honest, we didn't help with good intentions. We hate your Shenzhou civilization very much, and we also hate the Sweeper civilization very much, so we decided to help you, because you are too weak compared to the Sweeper civilization. Even if your civilization has the corpse of the MSI civilization, we don't think your chances of winning are very high. You can't do too much damage to the Sweeper civilization right now, and we want to see both you and the Sweeper civilization lose. To lose both, you must improve your strength now. ”

"We're going to give you some scientific and technical information about the high-dimensional space. Regarding the science and technology of high-dimensional space, our civilization has not found a practical way, we only have a little experience. I hope you can find a way to deal with high-dimensional attacks on our basis......"

"Alright, so be it, goodbye, no, I hope we never see each other again."

This is the end of the message of the Guardian civilization. Xiao Yu just listened quietly and didn't make any reply. The relationship between the current Shenzhou civilization and the Guardian civilization is very strange. These two civilizations were originally enemies of life and death, but because of the existence of the powerful civilization of the Sweeper, they were temporarily united.

The reason that the Guardian Civilization said was very reasonable, and the information handed over to Xiao Yu, Xiao Yu confirmed the authenticity of these materials just by looking at them. But Xiao Yu still had some doubts in his heart.

"Is it true that you came to help us just because you hate the Sweeper civilization......" Xiao Yu thought silently, "Since you have all decided to sail to the extragalactic system, why are you still so concerned about the Sweeper civilization?" Just because of emotional anger, do you come to help me? It may be a person's character, but it is unlikely to be a civilized character. Civilizations and civilizations should interact with each other rationally, and not with the emotional factors of individuals as they do. ”

Xiao Yu remembered that during the Battle of the Silver Heart, in order to prevent the Sweeper civilization from advancing to the seventh-level civilization, the Guardian civilization would rather pay a huge price than destroy itself. It is certain that at that time, the Guardian Civilization was already in the process of building the Star Road and was nearing the end, and it was basically impossible for them to have a relationship with the Sweeper Civilization after the voyage to the river system, so why did they still pay so much attention to the Sweeper Civilization?

"There's only one possibility...... The Guardian civilization is afraid that after the Sweeper civilization is promoted to the seventh level civilization, it will continue to run to the extragalactic system to deal with them. So why are you afraid? It's hard for me to understand how a level 7 civilization would run to an extragalactic galaxy just to wipe out a level 6 civilization. Perhaps, there is still some kind of secret between the Sweeper and the Guardian that I don't know yet, and the biggest possibility is that the Guardian Civilization has something or some kind of information, and this kind of thing is the Sweeper Civilization is bound to obtain, so the Guardian Civilization knows that even if they sail to the extragalactic galaxy, the Cleaner Civilization will not let go of themselves, so they have been thinking about the Sweeper Civilization. ”

"But it's still very contradictory...... Why didn't the Sweeper civilization attack the Guardian civilization with the Neutron Battlestar while it was still in the galaxy? Is there something I don't know about this? ”

Xiao Yu was very puzzled, and he couldn't understand these things at all.

"Leave it at that...... Let's analyze high-dimensional technology first. Hopefully, in the next few years, I can perfect this technology and finally find a way to deal with high-dimensional attacks......" (To be continued......

PS: Two more are over...... Went to sleep...... Tomorrow I have to get up early to take the civilized driving test, and I have to get a license, which is estimated to delay a lot of time, so tomorrow's update should be a little later.
