"You two are too much! There are still outsiders here!"

Sister Yue looked at You Xi angrily and kept stroking Ruoxi's head as if no one was around him, while Ruoxi was enjoying it like a kitten, and for some reason a little curious arose in her heart.

She has never experienced this feeling of touching her head.

As the princess of the Empire of Light, she grew up with the golden key in her mouth and only describes such things at the book level. It is absolutely impossible to be too embarrassed.

So when I first saw You Xi and Ruo Xi like this, I felt curious.

This kind of curiosity is fatal, and even You Xi's face became much more kind in her eyes. At least the other party gave her food and clothing, but did not drive her away.

"Sorry, that... let's talk about the main business."

You Xi took back his hand and sat upright at Sister Yue. Only then did the two of them start a deep communication.

"That numbered weapon actually represents the national weapon of our Empire of Light."

"There are 600 heavy objects in total, and f548 is the 548th artifact."

Speaking of this, Sister Yue's eyes became solemn.

"This time the channel launched by the mecha troops is a public channel, which means that all civilizations can receive these channels. If this passage is intercepted by the Dark Empire, then this star field will definitely not grow."

"Because the Dark Empire has always acted absolutely, as long as there is a planet of life nearby within a thousand light years, they will destroy it."

After hearing this, Yu Xi's breathing became a little heavier. The Dark Empire was so domineering, which means that once the news was found out by the Dark Empire, people would definitely be sent here again.

I don’t know if You Xi can still resist it.

"So you want me to help you save those mechas?" You Xi narrowed his eyes slightly and looked at Sister Yue in front of him.

"Yes, I will pay you the corresponding rewards!" Sister Yue nodded, looking like a businessman.

"Just think that I hired you, just treat it as a mercenary and follow me to rescue the trapped hostages. As long as the task is completed, money is not a problem!"

Sister Yue is confident to say this, because she is the princess of the Empire of Light. Can’t the fourth-level civilization satisfy a mere small civilization that has just crossed the first level?

"No hurry, let's talk about the function of this space detector, f54, etc."

Sister Yue hesitated on this issue for a moment and finally spoke.

"This thing is a high-tech product obtained from the alien space through hard work by our Empire Warriors. It can directly detect a person's general position and can reverse the time in a certain space."

"Time goes backwards?" You Xi was a little shocked. In the scientific community, the concept of time is actually a very special existence. Everyone knows that if you want to turn back time, you must surpass the speed of light.

However, in general theory of relativity, the speed of light is just a relative concept. Even if you are at the speed of light now, the light you see is still relatively maintaining the speed of light compared to you.

For example, if you shoot a beam of light on a plane with speed v, then the speed of light should be V-speed light s

However, this is not the case. The light emitted on the plane still maintains a constant speed. No matter from any situation, the light always exists and will not change due to any coordinate system transformation or anything.

Even the current civilization on Earth can only accelerate one particle infinitely to close to the speed of light.

But it can never reach the speed of light.

Because according to the formula in the theory of relativity, light has no static mass.

Particles have a static mass. If the particles are infinitely accelerated, the final speed will be infinitely close to the speed of light, and the closer they are to the speed of light, the harder it will be to accelerate.

Because it converts speed into mass, even if it tries hard to accelerate, the particles will only become infinitely close to the speed of light, but their mass will continue to grow.

This denies the so-called backflow of time and space from a microscopic level.

Rewind time is just a beautiful theory, and it has been established in the scientific community that is impossible.

Everything that happens will only continue to continue without going backwards.

This is the truth!

However, now someone tells you that I have a weapon that can turn back time, and Yu Xi’s first reaction is that he doesn’t believe it.

But if you don’t believe it, for the fourth-level civilizations such as the Light Empire and the Dark Empire, the existence of the earth is undoubtedly weak.

Humans cannot measure matter in the universe with their human minds.

Therefore, it is better to trust this kind of thing than to trust it without it.

"How much time can it flow back in time and space for up to what time can it flow back in time?"

You Xi looked at Sister Yue with a hint of expectation, with a glimmer in her eyes.

"It's a pity that this kind of time-space reflux is not the kind of time-space reflux you call it."

Sister Yue took out a pen and drew it in the void.

"For example, I've painted it in this place now, and I wiped it off."

As he said that, Sister Yue took out another special thing and wiped it into the air. The trace that was originally drawn quickly disappeared.

"The so-called time reflux means that these erased particles return to their original position, which means that at most, they can only restore some clues or some particularly large explosion details."

"This function may sound disappointing, but it is one of the few artifacts in the entire universe that involve the concept of time."

"And if we want to enter the fifth level civilization in the future, we must master the so-called time!"

Sister Yue's eyes were full of excitement, and she seemed to have seen the future level 5 civilization empire.

At that time, no one knows what kind of existence that kind of empire would be.

No one knows where the alien space comes from, and whether this universe is a farm where people compete and stand out. The catalyst for all this is the so-called alien space.

Of course, this kind of thing is not something that You Xi can consider at the moment. He just thought for a while and agreed to the mission of rescuing the mecha regiment, and at the same time put forward the requirement to study this weapon for a period of time.

Sister Yue agreed readily. In less than half a day, You Xi took Ruo Xi and the skeleton to the mysterious universe.

Qianqian and other planetary slaves were left in the dark world by Youxi, and the development of the dark world was accelerated.

If the task is successful this time, the reward will definitely be quite rich.
