The Earth is moving into the galaxy at a thousandth of the speed of light, which is slow.

At the same time that the Earth sailed into the galaxy, tens of thousands of autonomous mechanical aggregates were also sent out, carrying curvature engines, combined into hundreds of temporary warships, searching around the galaxy, looking for planets suitable for humans to build factories 10,000 years ago.

Soon, hundreds of makeshift warships were locked onto three planets not far from the star.

One of these three planets can be seen from a distance, and it is obvious that it is a living planet.

The other two, one of which is slightly closer to the sun, the whole planet has a red scene, which is obviously an extremely hot planet, but not too high, and is also suitable for building factories.

There is also one that is a little farther away from the sun, and the whole planet is cold all year round, but it is also not too cold, and it is also suitable to build a factory.

Lin Xu was still sitting under the big tree in the small courtyard, holding the tablet in his hand while chasing, while looking at the holographic projection displayed in the void around him, the images about the three planets transmitted in real time.

Hundreds of makeshift warships first disintegrated into tens of thousands of autonomous-powered mechanical aggregates over the three planets.

Then tens of thousands of autonomic machinery aggregates decompose again into hundreds of millions of small autonomic machines.

These small autonomous machines quickly changed their form and became unmanned detection machines that were the size of a palm or the size of a container.

Head to the three planets below, ready to search for them thoroughly.

The unmanned probe quickly headed towards the planet's ground, especially the suspected living planet, Lin Xu even saw all kinds of objects on the planet that were suspected to be man-made structures through the lens.

As the unmanned probe gets closer to the planet, the planet's gravitational pull begins to take shape.

Autonomous mechanical polymers have anti-gravity, and even after the autonomic mechanical polymers dissolve into small autonomous machinery, as long as the volume is not too small, they also have anti-gravity functions.

For example, an unmanned detector with the size of a container has an anti-gravity function, which can easily resist the gravitational pull of the opponent's planet and slowly move towards the ground.

But the palm-sized unmanned probe will not work, it is too small, and there is simply not enough space to install and generate anti-gravity equipment.

But it doesn't matter, there is a way.

At this time, it is the turn of the second generation of nanobots to appear.

Today's autonomous mechanical aggregates, each of which carries a certain amount of second-generation nanorobots.

After the autonomic machinery aggregate disintegrates, these nanobots are dispersed to various small autonomic machines.

Naturally, there are a certain number of nanorobots in palm-sized unmanned exploration aircraft.

Immediately, the second-generation nanobot was launched, forming a complex texture on the surface of the unmanned detector, which is a simple anti-gravity device with anti-gravity function simulated by the nanorobot.

It's not as sophisticated and reliable as a real anti-gravity device, but it's easier to use.

Even if the texture is damaged and the anti-gravity force fails, the nanobot can quickly regenerate the texture again.

Everything was carried out according to the established steps, Lin Xu watched the drama on the tablet while looking at the holographic projection, mainly looking at the planet that was suspected to have life.

He was very curious about what life on this planet would look like, so he took the time to take a look twice when chasing it.

But soon, the emergency information transmitted by the unmanned detector made Lin Xu unable to watch the drama.

"Master, the second-generation nanobots are suspected of discovering a large number of similar nanobots." Qiming's voice came.

"What's the situation? Nanobots of the same kind? Lin Xu didn't react for a while.

"During the operation of the second-generation nanorobots, they found that there were suspected nanorobot signal sources in the nearby air, but they could not contact them." Qiming replied.

"Is it a human remnant?" Lin Xu reacted immediately: "Why can't you contact it?" ”

"It's not certain if it's human. The reason why they can't be contacted is because the other party is too small, and from the perception of the signal source, it may only be one-tenth the size of our second-generation nanobots, or even smaller. ”

"Can I capture and bring it back for further analysis?" Lin Xu thinks that this may be a new generation of nanorobots that humans have come up again.

But until there is evidence of the matter, it is still necessary to treat it conservatively.

Autonomous machinery has returned home with suspected samples, and the next step will be to be tested by a laboratory.

Lin Xu nodded, and he didn't have the heart to watch the drama for a while, and waited for the test results.

Soon, the samples carried by the returned autonomic mechanical aggregates were tested and the results were obtained.

"The owner has confirmed that there are a large number of fugitive nanobots in the galaxy, the number is incalculable, and they are more advanced than the second-generation nanobots."

"A lot of escape? Not only on planets, but also in space? Lin Xu was puzzled.

When I was on Planet One at the proving ground, I was the only planet on it.

And at that time, the second-generation nanobots were not found everywhere on the planet where they escaped, at least there would be no nanobots in the air, but all of them settled on the surface of the planet, and then gathered together to become a magic crystal vein.

But the newly discovered nanobots on this planet are clearly not like this.

"Yes, this new nanobot is ubiquitous in this galaxy, and it will be denser on the planet and scarcer in space." Qiming replied.

"Is it human nanorobotics, is there a relationship between inheritance?" Lin Xu continued to ask.

"We have dismantled several nanobots, and we can already determine that they have the same technical context as the first-generation nanobots and the second-generation nanobots, and we can determine the human creations that are basically created for humans." Qiming said very cautiously.

"Is there any way to be sure that it is a human creation?" Lin Xu asked.

"There's an easiest way to do it, we need your hair cells." Qiming made a request.

Lin Xu immediately thought of the scene where he used his hair to conduct experiments on Miss Elf when he had not yet arrived at Planet 1 of the test site.

"No problem." Lin Xu said generously.

So Miss Qiu personally trimmed a small strand of Lin Xu's hair and handed it over to the chubby and round logistics robot waiting outside the door.

Then the logistics robot rose into the sky and took Lin Xu's hair to the laboratory very preciously.

Lin Xu, on the other hand, was waiting for the results of the test again.
