"What benefits do I get?" After being silent for a long time, Rahu asked this sentence.

"You can hear the questions." Fang Yuan replied with a smile.

"Is that also called a benefit?"

"Yes, you can get information from the outside world from the questions."

"Then you ask."

Rahu really wanted to get information from the outside world, and he had been locked up for six years and had no idea what was going on in the outside world.

Even the destruction of the Star Beast Civilization was told to him by the source three years ago.

Basically, on Earth, only Fang Yuan would occasionally say a few words to him.

Other researchers who study energy life forms will never have any communication with him, not even eye contact.

"Your home planet civilization is the Cleanser civilization, right?"

Fang Yuan originally wanted to directly ask about the inexplicable attack just now, but when the words came to his lips, he still decided to confirm this key information first.

"For the Carbon-Based Alliance, yes. But in reality, it's just a war between two life forms. Only you would call me the Civilization Cleaner of my home planet. Rahu replied.

"Your home planet civilization is still at war with a carbon-based civilization?" Fang Yuan continued to ask.

"That's right, I'll give you more information so you don't have to ask. My home planet, the civilization and the carbon-based alliance, have been playing tens of thousands of Earth years. ”

The year is a time scale set by human beings according to the revolution of the earth, and the time scale used by the Palese civilization is naturally not a year.

However, Rahu has been on Earth for decades, and as soon as he opened his mouth, it was directly converted into Earth years.

When Fang Yuan heard this answer, there was no change in expression on his face, but his heart was already turbulent.

The carbon-based alliance and the Palese civilization have fought tens of thousands of earth years, and the time scale of this war has exceeded the history of human civilization.

"Very well, the Cleanser ship issued an attack order today, but so far, nothing has been found to be attacked." Fang Yuan began to inquire about today's events.

The communication channel of the military scientific research class has been open, and so far there has been no news that the Cleaner civilization has launched an attack.

When Rahu heard this, he suddenly laughed.

Fang Yuan noticed that he was smiling, his eyes narrowed slightly, and he immediately understood something: "It seems that you have extracted a lot of valuable information from this question. ”

While speaking, Fang Yuan casually mobilized the energy of "235U", ready to detonate the nuclear bomb in front of him at any time.

If the Cleanser civilization does attack, it is likely that the Earth will evaporate in an instant.

It may be so fast that he doesn't even have time to react, if that's really the case, Fang Yuan is bound to kill the smuggler of the Cleaner Civilization in front of him first.

Luo Hu saw the energy in Fang Yuan's hand, his smug expression disappeared instantly, and he said in a deep voice: "You don't have to be so nervous, as you guessed, I did get a lot of useful information in this question."

"If I'm not mistaken, you're already doing curvature-driven experiments, right? And it shouldn't be far from mastering this technology. ”

Fang Yuan was aroused, and a smile tugged at the corner of his mouth: "In this case, the attack order of the Cleanser spaceship has something to do with the curvature drive?" ”

When speaking, the communication channel is open.

Military research classes and staff departments can hear it, and many people are always paying attention to information about the civilization of the cleaners.

Therefore, when the news of the attack order from the Scavitter ship and the curvature drive spread, headquarters immediately sent someone to contact the curvature drive laboratory to have someone check it.

Meanwhile.

Rahu also gave an answer: "Curvature drive will cause a dramatic change in the curvature of space, and this change will wake up the observer left behind by the spacecraft. ”

When Fang Yuan heard this answer, he thought of a lot of things in an instant.

"In other words, the curvature engine is the technology that really touches the sensitive nerves of the Palasse civilization."

Rahu didn't answer, but the smile he showed confirmed the suspicion.

Curvature-driven, a sign that civilizations can sail across star systems, is also the starting point for faster-than-light flight.

Fang Yuan had indeed guessed why the curvature drive would drive the nerves of the Palese civilization.

The reason is simple.

Before a civilization had curvature-driven technology, it could only use ion-engine-level thrusters.

The ion engine, supported by the solar furnace, can actually allow the spacecraft to fly out of the solar system.

However, the speed is too slow, and it will take thousands of years to reach the next terrestrial planet.

For thousands of years, the development of human beings has only been a few thousand years old, so you can imagine how long this time scale is.

Moreover, even if you reach terrestrial planets, they may not be habitable, and you may need to continue to search, and you may not be able to find habitable planets for thousands or tens of thousands of years.

A civilization that barely flies out of the galaxy with an ion engine is likely to drift in the dark universe and eventually die.

Therefore, for a civilization to truly sail across star systems, it needs to have a curvature engine.

For the Cleaner civilization, a low-level civilization, as long as it can't run out of the star system, can be pinched to death.

Once a low-level civilization has the ability to sail across star systems, it means that this civilization can spread the flame of civilization to the whole universe.

This kind of civilization, which can mine everywhere, is as troublesome as the spread of cancer cells.

As a result, the Cleanser civilization will prioritize the destruction of this civilization, strangling it to the point where curvature-driven technology is reached.

Fang Yuan thought about this clearly, and said in a deep voice: "So, the attack order of the Cleanser Spaceship is for the Curvature Drive Laboratory. ”

Without waiting for Rahu's answer.

The answer has been given in the laboratory: "All the experimental data and materials in the computer in the curvature-driven laboratory have been destroyed." ”

Fang Yuan's face suddenly sank, because things were even worse than expected.

Previously, Yang Yuping had said that there would be a major breakthrough in curvature-driven technology in one year.

However, the destruction of experimental data in the computer is now a major blow to research.

Fang Yuan slammed his fist on the table and yelled at Rahu, "Tell me, what is the observer!?" ”

Rahu sneered this time: "The Cleanser spaceship is almost here, and the countdown to the demise of the human race has begun. Now let me out, listen to my arrangement, and you may still have a chance to survive. Otherwise......"

When he said this, he smiled sadly, and the rest of the words were not finished, but the meaning was already obvious.

Fang Yuan's eyes narrowed slightly, and he snorted coldly, "Don't dream. If humanity can survive, you will still have a life. Otherwise, the moment the Cleaner ship appears, you'll die first! ”

Luo Hu said gloomily: "Until now, if you still refuse to listen to me, you are walking on the road to death!" ”

Fang Yuan rolled up his sleeves, turned around and strode away: "Even if the cleaner appears, he will have to pass me first." It's also an energy lifeform, how much stronger can the cleanser be than you? ”
