After Li Qingye inspected the ancient city of Titan, he went directly to Saturn's civilization fire research base through a synchronous robot.

This civilization spark research base is not far from the former Iapetus.

Titan is also a testing ground for the flame of civilization.

When Li Qingye came here.

Several people in charge who had already received the news quickly appeared in front of him.

"Mr. Chairman, welcome to your guidance." Zhao Changfeng, the director of the base, said while introducing to him: "This is Dr. Lexington, the head of scientific research, and this is the head of the test site, Loos?" Ali ......"

Li Qingye smiled and shook hands with everyone one by one, and then he asked, "I heard that the civilization fire can already be put into use?" ”

Dr. Lexington nodded: "There are not too many problems with the technology itself, but there are some problems with the delivery vehicle." ”

"Tell me about the specific problems you encountered?"

Dr. Lexington led the group to a small testing site.

And Los, who was in charge of the tests? Ali explained in a whisper on Li Qingye's side: "Chairman, this is the interstellar navigation simulation test site. ”

I saw that the entire test site was empty, with a length radius of 500 meters, and it was a spherical vacuum field.

In a moment, Dr. Nexington and Los? Ali and the others controlled the system and activated the test site.

Suddenly, a number of micro-flying machines were released into the spherical vacuum field.

Li Qingye could see at a glance that this was an interstellar space that simulated the solar system and the surrounding planetary systems.

After some manipulation, in this simulated test site, the fire of civilization and camouflaged comets emitted by the super electromagnetic orbital accelerator slowly flew out of the solar system.

"Is the speed only 22 kilometers per second?" Seeing this result, Li Qingye immediately frowned.

Dr. Lexington nodded helplessly: "Yes, Mr. Chairman, the fastest speed of the camouflaged comet is only 22 kilometers per second, if the speed continues to increase, the camouflaged comet will not be able to withstand it, and then gradually disintegrate in interstellar space." ”

"Is there any other way?"

"Yes." Dr. Lexington called up other backup options: "This is a backup plan, and there are two ...... that are more feasible at the moment."

Li Qingye took a look at it.

The two standby schemes are: casing scheme, casing + auxiliary thruster scheme.

The casing scheme is very simple, which is to add another layer of super-strong alloy to the camouflaged comet body, which can increase the initial speed to 80 kilometers per second.

The casing + auxiliary thruster scheme is based on the casing scheme, adding a nuclear fusion power system and ultra-high-speed plasma thruster, and with the stardust collector in interstellar space, the speed can be increased to 6,000 kilometers per second.

For these two backup plans, Li Qingye immediately understood the drawbacks.

In the universe, it is difficult for normal asteroids and comets to travel at speeds of more than 50 kilometers per second.

If you go with Alternate Option 1, that's a little better, at least it's not too much faster.

But if you use Alternate Option 2, the speed is almost 2% of the speed of light, which is not something that asteroids and comets can do.

As soon as any civilization detects an asteroid or comet that reaches 2% of the speed of light, it will instantly recognize that something is wrong.

Therefore, the possibility of exposure to Alternate Option 2 is very high.

For example, at this time, Homo sapiens has been densely packed with a large number of monitoring stations and monitoring satellites disguised as asteroids within a radius of 0.06 light-years in the solar system.

As soon as a star flying at a speed of more than 20 kilometers per second enters this range, it will be detected by these monitoring stations.

Of course, it cannot be ruled out that the other party's technology surpasses Homo sapiens too much and can avoid those monitoring stations and monitoring satellites.

However, the Homo sapiens company has absorbed a large number of technologies from the six-clawed civilization and the intelligent machine civilization, and unless it is a quasi-second-level civilization, it is difficult to avoid the monitoring of the Homo sapiens company.

Since Homo sapiens can monitor astral bodies with abnormal velocity, there's no reason why other first-tier civilizations can't.

Lowes? Ali saw Li Qingye's thoughts, and he said a supplementary plan:

"Mr. Chairman, if you are close to the boundary of the planetary system one light year, you can reduce the possibility of detection, if you slow down, reduce the speed to 15 kilometers per second, and abandon the metal shell and thrusters."

However, Li Qingye shook his head: "There is no need for that, the civilization that can detect the abnormal speed of the star is definitely not an ordinary zero-level civilization, and it is basically impossible for the civilization fire to develop obscenely under the nose of the other party." ”

"And the civilization that can't detect the abnormal speed of the star is most likely a zero-level civilization, or a wild planetary system that is uninhabited."

Everyone immediately reacted.

As Li Qingye said, it can be found that the abnormality has no way for the flame of civilization to take root; What can't be found is the habitat where the fire of civilization can develop.

After thinking about this truth, everyone suddenly became enlightened.

Dr. Lexington saw that the last problem had been solved, and a smile appeared on his face: "Chairman Yingming, it seems that the Tinder of Civilization plan can be implemented." ”

"Do you have any plans for this?"

Zhao Changfeng nodded: "Yes." He then investigates a detailed list of all the planetary systems within a 100-light-year radius around the solar system.

"We plan to divide into three phases with a radius of 10 light years, a radius of 10~30 light years, and a radius of 30~100 light years, and the first stage is a planetary system within a radius of 10 light years."

Zhao Changfeng then enters the data and calculates it at 2% of the speed of light.

Within a radius of 10 light-years from the center of the solar system, it would take about 500 Earth years to travel farthest.

However, the recent six-clawed giant star only needs about 150 earth years to reach the civilization fire, but it is a pity that the six-clawed giant star has a first-level civilization, and it must not be able to launch the civilization fire.

Another goal, which is 4.2 light-years away, will take about 210 years.

Li Qingye didn't care too much about this sailing time.

After all, under normal circumstances, the life expectancy of new humans is about 170~180 years.

If an absolute zero freezer chamber is used, it can be extended by thousands of years.

That is to say, if Li Qingye has no way to continue to extend his normal life at this stage, he can also use an absolute zero freezer cabin, wait for the technology to be more developed in the future, and then use new technology to extend his life.

Therefore, when the flame of civilization reaches the planetary system within 10 light years, Li Qingye can still see it.

As the general direction puzzle is solved, the launch time of the civilization fire is also determined, and it is expected that in 7 months, Homo sapiens will launch the first civilization fire to Proxima.
