The future can be changed, but it is very difficult to change the future, at least on the basis of the four-dimensional space, it is impossible to change the future, at least in the five-dimensional space.

With the current scientific and technological strength of the Earth Federation, there is no power to change the future, but by the time of the fifth-level civilization, it may be possible, so it is too early to say anything.

However, four-dimensional space technology has substantial help to improve the strength of the Earth Federation.

Not to mention the improvement of combat effectiveness, at least in the aspect of detection, there has been great progress.

Ten years after the Earth Federation developed four-dimensional space technology, the first four-dimensional space probe was built.

Previous detectors were designed based on three-dimensional space, which was greatly affected by various factors, and the detection range was also limited. Even the Earth Federation, which is at the peak of the fourth-level civilization, has a detection range of only tens of thousands of light years, and even the entire Andromeda Galaxy cannot be fully detected, and the effective and accurate detection range is even closer.

But now with the four-dimensional space detector, it has directly increased a dimension, and the detection range has been multiplied geometrically, although it is impossible to detect the entire local galaxy group, but the Andromeda galaxy can be detected completely, and it is an accurate detection.

When Xiang Qian saw the Andromeda Galaxy star map scanned by the four-dimensional space probe for the first time, he also had to be full of emotion. It's all about putting the Andromeda Galaxy on the table without any secret viewing.

"Starry sky, what's going on with those seven empty areas in the core of the Andromeda galaxy?" Xiang Qian looked at the star map for a while, and suddenly found that there were seven huge blank areas around the black hole at the core of the Andromeda Galaxy. In the blank space, let alone a star. Not even a meteorite.

It is important to know that around the black hole at the core of a galaxy is the place where the matter is most dense. It is impossible for such a blank space to appear, which is simply not scientific.

"Boss, those areas are blocked by a force, and the four-dimensional space probe can't scan the situation inside, and the star map displayed now is the star map obtained by the four-dimensional space probe after scanning." Starry Sky replied.

"What does the Academy of Sciences say, why is this happening?" Xiang Qian continued to ask.

"The answer given by the Academy of Sciences is that there is a shield in those seven places, and the power of the shield is similar to that around a black hole, after the power of the four-dimensional space is scanned there. Distorted by the massive gravitational pull, time is also distorted at the same time. Since the space around the black hole can be counted as a five-dimensional space, the forces of the four-dimensional space cannot be scanned.

And there can't be such a massive black hole inside those seven regions, so experts from the Academy of Sciences believe that those seven regions are artificially shielded. ”

Artificially shielded, then inside the seven blank areas, it should be a civilization that can use five-dimensional space technology, and the civilization level should be a fifth-level civilization.

Thinking of this, Xiang Qian felt that something was wrong. There are hundreds of thousands of native civilizations in the Andromeda Galaxy. But these civilization races are all fourth-level civilizations, and there are only seven fifth-level civilizations, which is also too abnormal.

If nothing else, the Earth Federation knows about the fifth-level civilization race. There are dozens of them, not to mention those who don't know.

According to the star map of the four-dimensional space probe, the entire interior of the Andromeda galaxy is now present. In addition to the native civilization races of the Andromeda galaxy that have not been wiped out, there are at least a hundred thousand civilization races. These civilized races come from the galaxy. There are also galaxies from the galaxy where the Bright Moon Empire is located, and there are also galaxies that Xiang Qian doesn't know.

These civilizations have broken through the fifth-level civilizations. It's just a matter of time, so if hundreds of thousands of fifth-level civilization races attack seven fifth-level civilizations, what effect will ...... You don't have to think about it to know.

But Xiang Qian didn't think that these seven fifth-level civilizations were easy to eliminate, otherwise it would be too easy. With the way the universe operates, it is impossible to let more than 100,000 civilized races pass the level.

"Let the four-dimensional space probe scan around those seven empty areas all the time, and report it as soon as it finds that a fifth-level civilization has attacked in the past." Xiang Qian said to the starry sky.

"Okay, boss."

Xiang Qian had already decided that he would never let the Earth Federation enter that area until he had figured out the situation inside those seven blank areas, or until he was sure enough.

Time passed slowly, and hundreds of years passed in the blink of an eye.

With the help of the four-dimensional space probe, it is much easier for the Earth Federation to find the native civilization races of the Andromeda Galaxy.

According to the star map, the fleets of the Pabo Dilong civilization and the Silver Wing civilization began to attack everywhere, although now that the upgrade technology of the Earth Federation has been collected, no one has too much scientific and technological information. If you miss this opportunity, no one knows if there will be another chance.

Therefore, Xiang Qian is going to get all the scientific and technological materials of several major classifications, anyway, now that he knows the situation of the core of the Andromeda Galaxy, Xiang Qian is not in a hurry to go there, just before breaking through the fifth-level civilization, he has collected all the information.

Now with the four-dimensional space probe, Xiang Qian can already understand the situation of the entire Andromeda galaxy. In the past few hundred years, more and more native civilizations in the Andromeda galaxy have been wiped out, and more and more civilizations have broken through the fifth-level civilization.

At this rate, in a maximum of one or two thousand years, the native civilization race of the Andromeda Galaxy will be completely wiped out, and at that time, everyone will also break through the fifth-level civilization.

When the time comes, we will know whether the civilized races within those seven regions are bluffing or really powerful.

At a time when all the native civilizations outside the core of the Andromeda Galaxy were in dire straits, in the metal disks around the black hole at the core of the Andromeda Galaxy, the seven huge seats were staring at the projection screen in front of them.

"There have been more than 10,000 civilized races that have erupted into fluctuations in the four-dimensional space, and it is estimated that the situation around our home planet has also been discovered, but I don't know if these civilized races will feel that we are easy to bully." A figure from a large seat spoke.

"The civilized races that have survived until now are not stupid, even if we don't shield the area around our home planet, they won't dare to attack us lightly."

"When they all become fifth-level civilizations, that is, when they come to attack us, I really want to know what kind of mood they will feel when they are about to crush us when they suddenly find out that they are the objects of crushing, I really look forward to it."

"Hmph...... Crush them, and don't forget, there can be human civilization among them, and you won't be able to destroy them when the time comes. ”

"That human civilization seems to be in the area controlled by your Three-Eyed Clan, and even if it is destroyed, it will destroy your Three-Eyed Clan first. But don't worry, we'll take revenge on you Three-Eyed Clan when the time comes. ”

"It's not certain who will help who take revenge, okay, in the end, I talked with you for tens of thousands of years, and it's time to go back, everyone is free to let me go first."

"I'm going too, go back and get ready, don't scare them in the first place, it's not fun."

"That's a good idea, I'll go back and prepare it."

The figures of the seven giant thrones departed one after another, and only the projection in front of the seat was still working inside the massive disk. (To be continued......)
