Three days later.

The Shenzhou returned to the Earth's spaceport in tatters, as if it had just returned from the battlefield of death, and the hull was so tattered that it seemed as if it would disintegrate with another shell.

The Shenzhou was moored at the spaceport, and the personnel on the battleship disembarked one after another.

"How did this happen?" When the logistics maintenance team saw the appearance of the Shenzhou, they couldn't help but ask such questions.

Niu Dazhi, who was the first to step down from the Shenzhou, had messy hair all over his head, and said with a sluggish face: "God knows what we have experienced, Fang Yuan, this neurotic, said that it can't be faster, it can't be faster, he still has to speed up......"

10% speed of light, this is the final result of the Shenzhou test curvature engine.

For ordinary people, just looking at the numbers, they will feel that they have not even reached the speed of light, and they cannot feel the meaning at all.

However, this data is a thunderbolt in the minds of scientists.

Only those who truly understand physics understand how exaggerated the speed of light is at 10%.

Under the framework of the theory of relativity, matter with a resting mass cannot reach the speed of light, and the closer it is to the speed of light, the greater the energy required, up to infinity.

Curvature drive is to change the curvature of the universe to achieve ultra-high speed.

Fang Yuan, with the assistance of the Warframe Curvature Module, could only reach 1% of the speed of light.

It is conceivable how terrifying it is that the Shenzhou test curvature engine reached 10% of the speed of light.

……

After the curvature engine test, all data is sent to the Curvature Drive Lab.

Yang Yuping led the scientific research team and immediately began to sort out and analyze the data.

"Professor, professor......" Fang Yuan had a question he wanted to ask.

"What? I'm busy, I'll talk about it in a few days. Yang Yuping waved his hand, didn't want to pay attention to Fang Yuan, and plunged into the data model.

"The Shenzhou has only reached 10% of the speed of light, and I feel that the curvature engine of the Palese civilization spacecraft should not have such a little speed." Fang Yuan directly said the doubts in his heart.

According to the previous speculation on the scientific and technological level of the Palassee civilization.

The curvature engine of the Palasse civilization ship is absolutely capable of faster-than-light, and it may be many times exceeding.

However, when Shenzhou tested the Palasse curvature engine, it only reached 10% of the speed of light, which is very unreasonable.

"Professor, did you not do a good job of modifying the curvature engine, and reduced the performance?" Fang Yuan asked.

"No way. It's still a bit difficult for us to build a curvature engine now, can't we make a curvature engine? The reason why it failed to exceed the speed of light was because there were three curvature engines on the Cleaner spacecraft, and Shenzhou only tested one. Yang Yuping casually replied for a reason.

Fang Yuan suddenly thought of a possibility: "Then is there a way to repair the complete Cleaner Ship?" ”

"This ...... It can be repaired to a certain extent, but it takes a while to restore it to its original intimacy. Yang Yuping has not carefully analyzed this question, so the answer given is not very positive.

"As long as the power engine can basically reach the original level, if it can fly faster than the speed of light, then the plan to destroy the ε star gate of Pegasus can be executed, which will give humans a long buffer time." Fang Yuan spoke his mind.

Yang Yuping has been engaged in scientific research all his life, and he usually doesn't think so deeply, but when he heard Fang Yuan say this, he also felt that it made sense:

"This is a good idea, if the star gate of the Palese civilization is destroyed, then it will be difficult for the Palese civilization to send a fleet to the solar system in a short time. Yes, the center of work should be placed on the repair of the Washer ship. ”

Once the goal is determined.

The Super Tech Lab has been officially established to restore the Cleaner spacecraft.

With the help of Eve's mechanical bug-level abilities, the repair work is very fast.

Coupled with the mature technology of strong nuclear force materials, it is also very smooth when repairing the shell of the Cleaner spacecraft.

In the end, it only took more than a month to repair all the Cleaner spacecraft.

"To what extent can it be restored?" Fang Yuan saw the repaired Cleaner Spaceship and asked a key question.

"More than 80% of the performance is definitely there, and if you just talk about the sailing speed, it can be almost 90%." Yang Yuping answered.

The repaired Cleaner ship has been renamed the "Counterattack" Star Destroyer.

Subsequently, the military scientific research team boarded the counterattack star destroyer and conducted a test flight.

Finally, under the powerful curvature engine, it reached 10 times the speed of light.

This is the speed of conversion driven by curvature, not the actual speed of driving energy.

"10 times the speed of light, you still can't carry out the mission of destroying the ε stargate of Pegasus."

After the final curvature speed came out, Fang Yuan found that the speed was still not enough.

The constellation Pegasus ε 673 light-years from Earth, which means that it would take 673 years to travel at the speed of light.

Even if you go at 10 times the speed of light, it will take 67.3 years.

That's a long time, enough time to change a lot of things.

Therefore, even if you go to the ε Pegasus at 10 times the speed of light, it is difficult to cross such a distance.

"Something is wrong, the Scavitter ship should be more than 10 times the speed of light." Fang Yuan still felt that something was wrong.

Previously, when the Cleaner spacecraft returned to the solar system, it also pointed to where it had departed from, and it only took more than a month to arrive in the solar system.

The diameter of the solar system is about 4 light-years.

In other words, if the Cleaner spacecraft were flying at 10 times the speed of light, it would simply not be able to fly back from outside the solar system within a month.

So, there must be a secret that hasn't been discovered.

When Fang Yuan saw Rahu again, it was still in that hemispherical building.

"When will the promise of giving me more space for events be fulfilled?" After Luo Hu saw Fang Yuan, he took the initiative to ask to fulfill his promise.

Fang Yuan had promised him before that as long as he was willing to cooperate, he would give him more space to move, provided that the scientific and technological strength reached a reassuring height.

"There's no hurry, I still have some questions to figure out. According to calculations, it took just over a month for the Cleaner spacecraft to fly back from outside the solar system. This is simply not something that a 10x sonic curvature engine can do. Fang Yuan said the question in his heart.

"It's useless for you to ask me, you only know the curvature engine, not the curvature generator, or in words that you can understand more easily, the curvature generator is like a slingshot that can be launched by a spacecraft to reach extremely high speeds." Rahu replied.

"Curvature generators, it takes time to build, right?"

When Fang Yuan heard his explanation, he immediately understood what a curvature generator was, and at the same time discovered the loophole in Rahu's answer: "Moreover, it is definitely not easy to build a curvature generator, and it is impossible for the Cleaner Spaceship to build a curvature generator anytime and anywhere. Even if you have a curvature generator, how much more can you increase the speed? So, it can't be a curvature generator. ”

"If it's not a curvature generator, then it can only be a more powerful technology mastered by the Palese civilization, such as dimensional technology, or a wormhole detector, which specializes in finding naturally formed wormholes in the universe, so as to pass through wormholes, cross long distances, and reach wormholes around the destination." Rahu explained again.
