Rebirth of the Super Battleship

Xiao Yu had previously conducted some research on four-dimensional space and had also made some conjectures about it.

The increase in dimensions followed a certain pattern, mainly divided into two aspects. First, lower-dimensional spaces are completely visible to higher-dimensional spaces. Second, lower-dimensional spaces are completely indefensible against higher-dimensional spaces.

Simply put, imagine a piece of paper representing a two-dimensional world. If you draw a circle on this paper, the inside of that circle would be enclosed to the two-dimensional beings living on the paper, they wouldn’t be able to see inside the circle. However, a being from the three-dimensional world could easily see into the circle without any obstacle. This is the complete visibility of the two-dimensional world within the three-dimensional one. In the two-dimensional world, there are no secrets from the three-dimensional world. Accordingly, Xiao Yu speculated that the three-dimensional world would also be completely visible to the four-dimensional world.

As for being indefensible, the circle analogy could still be used. Suppose the circle represents a fortress in the two-dimensional world, extremely sturdy and indestructible. No two-dimensional being could ever break into the circle. However, for a three-dimensional being, it’s a different story, they could easily bypass the fortress walls by utilizing “height,” a dimension that does not exist for two-dimensional beings. In other words, in the two-dimensional world, no matter how tough an object’s exterior is, it can never block a three-dimensional being. Similarly, no matter how strong the shell of a three-dimensional object is, it cannot stop a four-dimensional being.

This was a simple explanation of the two features: complete visibility and indefensibility.

Xiao Yu had thought about this long ago. But seeing it with his own eyes, this was the first time.

What unfolded before Xiao Yu was a world of complete visibility and indefensibility.

In the three-dimensional world, a spaceship was sealed to Xiao Yu, a star was sealed to Xiao Yu, a Luka One individual was sealed to Xiao Yu, a cell, an atomic nucleus, all of these were sealed to him.

But after obtaining a four-dimensional perspective, all of these became open and transparent before Xiao Yu’s eyes. Xiao Yu could see every detail inside any object in front of him.

He could see the outer hull of a spaceship and at the same time see its inner walls. He could see the skin of a Luka One individual while simultaneously seeing their heart. He could see the surface of the heart while simultaneously seeing the blood vessels inside. He could see the blood inside the vessels at the same time…

In the three-dimensional world, there are no secrets for the fourth dimensional beings.

If you lost a ring in the three-dimensional world and didn’t know whether it fell under the bed or into a crack in the desk, once you had a four-dimensional perspective, you could see the ring directly without moving anything.

The four-dimensional world was that miraculous.

However, complete visibility also meant an enormous amount of information. Fortunately, Xiao Yu had an immense computational capacity, which prevented him from becoming dizzy from the overload.

“I can observe all of this through optical instruments, which proves that light can propagate through the fourth dimension. I can feel gravity, which proves that gravitons can also propagate through the fourth dimension. This means that three-dimensional objects still possess mass within four-dimensional space. Four-dimensional space is truly incredible,” Xiao Yu marveled.

He then operated a robot and directly passed it through a wall.

Neither the wall nor the robot was damaged, because the robot passed through the wall via the fourth dimension.

No matter how sturdy the wall, no matter how tight the defense, it had no protective ability against objects moving through the fourth dimension.

At that moment, Xiao Yu thought of many things.

“If I could master the fourth dimension, wouldn’t any enemy before me be like a paper tiger? No matter how strong their ship hulls are, even resistant to supernova explosions, they would still be completely defenseless against attacks from the fourth dimension…”

“However, the fourth dimension seems to be a technology only grasped by Level 7 Civilizations. As for what Taihao said about failing in evolution and teetering on the edge of destruction. I don’t fully understand, but I can perhaps simply regard it as an existence between a Level 6 and Level 7 Civilization. Taihao can only possess incomplete four-dimensional abilities, does this mean that once you truly reach Level 7 Civilization, you can fully master four-dimensional space?”

“Even the Sweepers and Guardians haven’t grasped this technology,” Xiao Yu sighed, operating all instruments at full capacity to gather data. “Taihao said he belongs to the Type C Taihao Civilization. I wonder what kinds of special abilities the Type A, Type B, and Type D Taihao Civilizations possess. And just how many types of Taihao Civilizations are there?”

“The universe’s vastness and wonder truly exceed anything I can imagine,” Xiao Yu thought with deep emotion at that moment.

“Little one, have you seen enough? Time to leave.”

At that moment, Xiao Yu received a message. Immediately afterward, everything before his eyes blurred, and the world seen through optical instruments returned to normal.

The sights of four-dimensional space were like a dream.

“It really was miraculous,” Xiao Yu sighed.

“Miraculous? I actually rather miss the three-dimensional perspective,” Taihao said. “Civilizations can only evolve through collision. I hope that during my journey in the Milky Way Galaxy, I can achieve a breakthrough.”

“Collision?” Xiao Yu’s heart tightened. He cautiously said, “In our Milky Way Galaxy, according to what I know, there are two — no, at least three super civilizations.”

“Oh? Tell me about them,” Taihao asked with keen interest.

Suppressing the excitement in his heart, Xiao Yu organized his words and said, “First, we usually call them the Sweepers. This civilization is incredibly powerful, so powerful it’s beyond imagination.”

“Sweepers, huh?” Taihao said. “Judging from the name, it seems to be a destructive civilization that eradicates any civilization it perceives. It’s somewhat similar to me. But slaughtering weak civilizations holds no meaning for me anymore. Otherwise, little one, you would have been dead long ago.”

Hearing this, Xiao Yu didn’t know how to feel and could only secretly curse in his heart. ‘Madman. They’re all madmen.’

“The second civilization we call the Guardian Civilization,” Xiao Yu continued. “This civilization is in opposition to the Sweepers.”

“Guardian Civilization? Judging from the name, it sounds like a civilization that suppresses the development potential of weaker civilizations in order to gain Luck Value. However, that kind of trickery only works on Level 4 and below civilizations. Level 5 civilizations basically won’t fall for it. Once they encounter Level 5 civilizations, they tear off their masks and become Sweepers themselves. It’s a very hypocritical kind of civilization,” Taihao commented concisely.

There was an important piece of information hidden within these words.

“Level 5 civilizations basically won’t fall for it?” Xiao Yu pondered. “Does that mean that besides the Sweepers and Guardians, there are also many independent Level 5 civilizations in the Milky Way Galaxy? This would be a huge variable. Right, Taihao mentioned before that an information storm could severely damage Level 3, Level 4, and Level 5 civilizations. A Level 5 Civilization wouldn’t go extinct but would suffer serious losses. Maybe this is my chance, if I can find an opportunity to raid a Level 5 Civilization…”

Xiao Yu thought silently.

“The third civilization is the Type D Taihao Civilization I mentioned to you before,” Xiao Yu said.

“I have little interest in that Taihao Civilization. It evolved differently from me, and its evolutionary path holds no reference value for me. If I had no other targets, I wouldn’t mind fighting it to pass the time. But since there are other civilizations, forget it. I’m much more interested in the Sweepers and Guardians. In the upcoming period, I’ll seek them out, wipe them out, and seize all their technology,” Taihao said casually, as if he were simply talking about slaughtering chickens.

“The Sweepers’ strength might exceed your expectations,” Xiao Yu said. “I once heard that they hollowed out a neutron star and transformed it into a Neutron War Star. They also once killed a powerful Specter Race individual…”

“A Neutron War Star? A Neutron War Star?” Taihao suddenly grew excited. “A Neutron War Star?! Then I must meet them. To modify a neutron star into a war star, without complete four-dimensional technology, who would believe it? I must find them, kill them all, and plunder their technology.”

Xiao Yu quietly breathed a sigh of relief.

For the sake of his own survival, Xiao Yu didn’t mind using some tricks to eliminate some enemies.

“That’s enough information. As thanks, little one, I’ll handle the upcoming information storm. Oh, and during the storm, some very interesting phenomena might occur. You should pay attention and gather information.”

“Information storm? Isn’t it supposed to arrive in a year?” Xiao Yu asked in confusion. “Also, what exactly is the information storm? What interesting phenomena? How should I gather information?”

“I’m currently traveling via a jump-style Faster-Than-Light Travel toward the edge of the Milky Way Galaxy. Through four-dimensional scanning, I detected the presence of powerful civilizations there. Moving close to the speed of light alters the flow of time, you know that, right? That’s right, from the outside perspective, a year has already passed. In one hour, the information storm will arrive.”

“Prepare for observation, little one.”
