The stars, but they become the gray wind

"Is this... a line of gravity? So, come to think of it, the form of force in the fifth dimension is indeed a constantly vibrating string?"

Kaleese observed the lines that stretched from the room and all the surrounding objects, without thickness, width or length.

The room where Calisi was was so large that it was almost impossible to measure. Before coming in, she had only thought that the volume of the five-dimensional space inside a palm-sized Metatron's cube should not exceed the diameter of a massive giant planet in three-dimensional space. Cabot had only mentioned that the space inside the five-dimensional hypercube inside the Metatron's cube could easily fit a planet. It was not until she came in that Calisi realized that Cabot's description of this place was a bit too understated.

Although it seems that this room is infinitely overlapped and extended in all directions, the three-dimensional distance from one end to the other of a single room seems to be more than 10 billion kilometers. Although it is indeed inappropriate to measure the length in three-dimensional cognition in five-dimensional space, according to Calisi's observation, the three-dimensional diameter of a single room in this infinitely overlapping room is more than six astronomical units.

The whole room was very bright. Carlisle did not see any light source or heat source in the room that could produce illumination. The trajectory of photons in this space seemed to completely defy the common sense of the three-dimensional universe. Obviously, if necessary, one could even directly insert a star into this space as a light source, but Carlisle did not find anything that looked like a light source in the room.

"Strange, it should be very dark here. Even if it's a five-dimensional hypercube, without any light source inside, it should be as dark as space in the three-dimensional universe. So... where does this light come from?"

Floating in the air, Kalisi couldn't find a support point. She tried to activate the single-person wormhole teleportation device and was surprised to find that the single-person micro wormhole teleportation was still usable. However, after she passed through the small wormhole she created, she found that the landing point at the other end of the wormhole seemed different from what she had calculated. In its calculation and positioning, the exit at the other end of the wormhole should be 1000 kilometers away, but in her perception, the exit at the other end of the wormhole appeared only less than a few hundred meters away.

"Sure enough... Coordinate calculations in high-dimensional space are completely different from those in three-dimensional space."

"We need to find the correspondence between coordinates and distances in high-dimensional space and low-dimensional space."

"Good, you learn quickly. The fact that you've thought of this shows that you're quite good." Cabot's voice rang out from the purple-haired girl's mind.

"It's similar to your high-dimensional space jump engine. A long distance in low-dimensional space is only equivalent to a short distance in high-dimensional space. Although movement in a high-dimensional coordinate system can still create wormholes that exist in higher dimensions, the coordinate calculation and distance of the wormhole will produce a completely different correspondence from that in low-dimensional space."

"For example, the wormhole you just used to teleport you 1000 kilometers away only allowed you to teleport a few hundred meters. This is also because distances that are only astronomical in three-dimensional space will also be compressed very short in five-dimensional space."

"So instead of taking the time to gossip, why don't you just teach me how to move in a high-dimensional coordinate system?" Carlisle's body was still floating in the air without gravity.

"You are still on one of the surfaces of the high-dimensional hypercube. I will pass on to you the calculation method for the wormhole coordinate coefficients in the high-dimensional space. You just need to follow this coordinate method."

A piece of information was transmitted into Carlisle's mind. This was the five-dimensional space that contained an additional imaginary coordinate, which was the calculation method of the time axis coordinate, namely the x, y, z, t and i axes.

According to the new coordinate calculation method, Kalisi reopened the single-person wormhole transmission device and successfully created a wormhole exit at the predetermined location 1000 kilometers away. After passing through the micro wormhole transmission portal, Kalisi's feet once again touched the ground firmly.

The purple-haired girl looked upwards, and countless objects overlapped and intertwined in her eyes. Each object seemed to exist in infinite copies on the same extension line. Kaliqi knew that was the timeline of the object. This was also the first time she had seen the timeline of an object intuitively. On an extension line, each overlapping shadow was a time clone copy of the object at a different time point. In the five-dimensional space-time, time does not have only one direction, but there is a negative axis. In this special five-dimensional hypercube space, Kaliqi can travel in reverse time in a very intuitive way. Time, on a higher dimensional scale, is just another physical dimension that can be artificially changed like length and width.

There were countless extension lines composed of materialized gravity above, below, and around Carlisle. She leaned down and tried to pluck one of the gravitational strings. Immediately, some disturbance occurred on the surface of an infinitely extended cube in the distance. In the girl's visual perception device, the light emitted from the cube changed. The nanomechanical aggregate body, which highly integrated almost all detection functions, detected a weak gravitational wave propagating outward from the gravitational strings under her feet and the cube in the distance.

"By disturbing the materialized gravitational strings in higher-dimensional space, objects that exhibit low-dimensional properties in higher-dimensional space will undergo corresponding changes? Interesting."

"Although you have almost learned how to move in high-dimensional space, you might as well go to this coordinate and take a look. There are some things there." Cabot's voice sounded again.

"There?" Carisi raised his head and tried to see what was there directly through his eyes, on the timeline of the materialization of this five-dimensional hypercube.

She saw this infinitely repeating and overlapping room with a diameter exceeding six astronomical units in a certain direction in the distance. At a certain point in the timeline, this room seemed to contain something complex, unlike the room at the current point in time he was in. It was empty, with almost nothing visible except some strange geometric shapes.

"What's that?"

"Some things I've collected from various points in your future and from my own collection."

"When exactly will this future reach?"

"It's much further than you think."

"Tell me about the other me that I first met?"

"Did you find out?"

"Are you saying that my other self wasn't telling the truth about how far into the future I came back from?"

"Haha, actually, the future you didn't lie. She did return to the past from a relatively not-too-distant future. It's just that before returning to the past, she had been to a very distant future."

"Just like some of the things in this five-dimensional super-cube, it's a point in time that's much further into the future than you can imagine."

…………

After teleporting through the single-person wormhole to the current time on the timeline of the room, Kalisi immediately felt the difference in the room at this point in time. Within this space, which was six astronomical units in diameter, countless spaceships, aircraft, and giant artifacts were parked in the air. The floor also seemed to be filled with rows of strange containers. These containers, along with the spaceships, aircraft, and giant artifacts in the space, were so densely packed that the end was almost invisible.

"these are?"

"What you build at various points in the future," Cabot replied calmly.

"More accurately, one of those time-cloned copies of those things."

Carlisle glanced at the densely packed spaceships and aircraft of various shapes and sizes parked in mid-air. She saw many familiar things among them, dozens of night fighters ranging in size from a few hundred meters to tens of kilometers, thousands of subsequent spaceships that were obviously similar in appearance to the Fantasy Light, and at least hundreds of millions of spaceships and giant man-made objects of various models that she couldn't even name. These spaceships ranged from tens of meters in size to hundreds of kilometers in size.

When her sight passed one of the spaceships that was obviously abnormally large, the corners of Carlisle's mouth twitched.

"Hey! This thing doesn't seem to be a product of Sky Star, right?"

"Indeed, she's not. She's a small toy I used before—United Glory MK3."

"You call this a toy?" Carlisle asked with a twitching face, pointing at the triangular flying-wing battleship whose long axis was at least close to one astronomical unit.

"In the early days of the alliance, this thing could indeed be considered military equipment, but now, at best, it's just a small toy."

"So you just stuffed a United Glory in there?"

"What, don't you like it?"

"No, I love it. I never had the chance to touch this thing before."

"If you want it, just take it out and use it."

"This thing's functions are basically kept in near-perfect condition. All you have to do is enter your identification information."

"A thing the size of United Glory is quite outrageous even on Sky Star. I don't think we will need it for the time being. However, we still need to enter our identity information in advance."

"I should be able to teleport directly into this United Glory, right?"

"Not really. When the United Glory is docked, the ship's teleportation shield is activated by default. Any form of unauthorized teleportation from the outside world to the ship is impossible."

"Then how do I get in?"

"Wait a moment. There's a hangar underneath it. I'll open the door. You can use the fixed transmitter inside the ship to find a terminal and modify your identity and permission information directly."

.........

Kalisi appeared one astronomical unit away from the main body of the United Glory. No form of teleportation could be carried out any further. The United Glory, which was in the default low-power operating state, had activated a teleportation shielding field that would make any form of teleportation and superluminal navigation impossible within a radius of one astronomical unit with itself, not even the high-dimensional space jump engine currently used by Sky Star.

And this is said to be only the low-power operating state of the transmission shielding interference field on the United Glory that uses extra-dimensional matter. For the Sky Star, which is a dependent of the United Fleet, this is still a black box technology. At the highest power operating state, with the United Glory itself as the center, a super interference field with a radius of one light year will completely fail any superluminal engine and transmission device. The area where the United Glory is located will become a "black zone" that no superluminal spacecraft can escape, no matter whether these superluminal spacecraft use warp speed navigation in the three-dimensional universe or wormhole jumps. , high-dimensional space jumps, sub-space navigation through subspace or subspace, any superluminal navigation method will be unusable in the interference field of the United Glory. According to Cabot, this is achieved through a special application of the black box technology of super-dimensional matter. She is not easy to explain the specific principle. As long as it is within the superluminal speed and transmission interference field of the United Glory, even the unreasonable drive of the Zelli Night Fighter, which modifies the local laws of cosmic physics to achieve superluminal navigation, will be seriously affected and become unusable.

Calisi found a usable small Zerri Night Fighter near the United Glory. Due to the interference field, Calisi could not approach the United Glory on her own, and the Night Fighter's FTL drive was also unusable. Calisi could only fly the Night Fighter using the conventional inertia-free engine to gradually cover the last astronomical unit of distance.

Even for light to fly across a distance of one astronomical unit, it takes more than eight minutes. Of course, the time axis in this five-dimensional hypercube does not have only one direction.

Kalisi did not drive the inertia-free space-time defect drive of the Zelli Night Fighter to the maximum speed, because the automatic defense system of the United Glory not far away seemed to be still on. If something approached at too high a speed, it would most likely be identified as a hostile target and intercepted by the automatic defense system. For safety reasons, the Zelli Night Fighter piloted by Kalisi flew at an extremely low speed of 30,000 kilometers per second while approaching the main body of the United Glory.

"At this speed, it will take about 1.3 hours to reach United Glory. Can't you just turn off the automatic defense system?"

"Of course you can, but manually turning off the automatic defense system that's on by default is very troublesome, and I'm too lazy to do it manually."

"Uh... never mind. But... how do I change the ship's permissions after I get in? We're your nominal dependants, but we're not officially members of the Combined Fleet, are we?"

"Don't worry about that. Once you get on board, find the terminal and leave the rest to me."

At one tenth the speed of light, after more than an hour's voyage, the Night Fighter finally entered a hangar beneath the United Glory. The moment the Night Fighter entered the hangar, it was hit by no less than hundreds of light beam scanning signals. However, after all the scanning signals detected the special identification marks and codes unique to the United Fleet's creations on the nano-mechanical aggregate life form and consciousness level carried by the Night Fighter, all the security detection systems entered standby mode and directly ignored the existence of the Night Fighter.

"Oh my god, I was so scared. I thought I was going to be evaporated."

"Don't worry, as long as you don't do anything destructive on this United Glory, the ship's security detection system won't identify you as a hostile target."

"Including you, and the entire Sky Star civilization, they all bear the 'mark' of the Combined Fleet. Under the influence of this 'mark' that affects almost the entire civilization, any creation of the Combined Fleet will not actively show any form of hostility. Unless you first actively engage in hostile and destructive behavior, otherwise, in our identification system, the Sky Star civilization will be identified as our protected dependents."

"You should have told me earlier... You almost scared me to death just now. I almost thought the automatic defense system would blow me to pieces."

Jumping off the night fighter that was hovering several meters above the ground, the purple-haired girl stepped into the interior of the United Glory's ship for the first time. She looked around and found that the area of ​​this hangar seemed unprecedentedly vast. From the hangar floor to the height of the ceiling, it was thousands of kilometers. The purple-haired girl had no doubt that even a dwarf planet the size of Pluto could be easily stuffed into this hangar. At the top of the hangar, the purple-haired girl even saw naturally formed clouds and atmosphere.

After searching for a while in this huge hangar, Kalisi found a small portal and control terminal that was closed.

"We've found the small transporter and terminal inside the ship. How do we use them?"

"Put your hands on it and relax."

"Ah? Relax your mind? Why do I need to relax my mind?" The purple-haired girl just finished speaking, and she felt that something was not right with her condition. It seemed that Cabot transmitted something to her. Calisi felt that she was gradually losing control of her body.

"Relax... It's me, Cabot." Carlisle opened her mouth and said, her pupils had changed from the original dark purple to the unique blue of Cabot.

Although Kalisi lost control of her body, she could still see, hear and perceive everything in the outside world, but it was difficult for her to influence the macroscopic material world through her body.

"This feels a bit weird..."

"Although I treat you as my daughters and you are considered my dependent civilization within the Combined Fleet's system, you currently do not have the authority to directly operate the Combined Fleet's technological products."

"I need to borrow your body to modify the authorization authentication of this retired United Glory and yours in the United Fleet system." Cabot pressed his hand on the terminal in front of him, and the operating terminal of the transmitter displayed the unique Nirvana Dragon symbol of destruction and rebirth of the United Fleet.

[Identity confirmed, Senior Star Governor: Cabot, Serial Number: CV16 Lexington, welcome back, Ms. Star Governor Cabot.]

[The permission authentication is being modified. Are you sure to add a new permission authentication? ]

【whether】

Cabot, who was controlling Calisi's body, pressed [Yes] on the operating interface. In an instant, a huge amount of information flooded into Calisi's mind and flashed across the operating interface in front of her at a speed so fast that it was blurred.

Despite the huge total amount, Kalisi still saw several familiar names and numbers among them, Aze, Yuuki, Anna, Elena, Renlong, Luoying, Noshalin, Nina... There are as many as trillions of names and numbers in this newly added permission authentication list information.

"This means... you've added every individual in the entire Sky Star civilization to the authorization verification process?"

"Yes, since I already regard you as our children and relatives, then it is normal for me as a mother to give you a small toy, right?"

"But...this toy is a bit too outrageous."

"So, as long as you're a Sky Starman, you can directly use all the functions of this United Glory?"

"Of course, but considering your current life form, extradimensional matter, remember that it is still a black box that is difficult for you to understand."

"But this is not a big problem. If you are willing at some point in the future, I can always turn your entire species into a united fleet of ship girls like me who can truly master extradimensional matter."

"However... judging from the future I've arrived at, you don't seem to have that desire in the short term. In that case, I won't force you. You can become one of us when the need arises."

Note: 5-dimensional space - space composed of five-dimensional hypercubes, it has five dimensions: length, width, height, time and another dimension, and a space-time with imaginary coordinates, namely x, y, z, t and i.
