Humanity is missing, luckily I have billions of clones

At this moment, Li Qingsong couldn't wait to go to the Earth to see what was happening there.

How could there be no industrial landmarks? How could there be no landmarks? So many years of development, so many people, so much advanced technology… just gone?

There is no trace left at all?

It’s a pity that Li Qingsong can’t go at the moment.

Not only can't people go there, it's impossible to even send a probe there.

Don’t be fooled by the fact that Li Qingsong has built a huge space base and owns a fleet of hundreds of warships, which seems to be extremely advanced technology.

But in reality, these are just for show.

The emergence of these things is entirely due to a most important premise.

Roselle has low gravity and no atmosphere.

The advantages of these two conditions were so great in the early stages of civilization development that Li Qingsong possessed so many space creations even though the human civilization of the national era was inferior to that of the human civilization of the national era.

It seems to be a simple matter of launching a probe, but this first involves a route planning problem.

Without a deep understanding of the planets in the solar system and without knowing their detailed orbits, masses, and gravitational field changes, how can we plan our route?

It is impossible to even plan the route, let alone use their gravity to accelerate or decelerate, let alone how to take various complex factors into consideration and make the final route calculation.

Launching a probe is not like just throwing it over with great force.

Secondly, there is another issue to consider.

How can communication be maintained when the distance is so great, even as high as 15 billion kilometers?

Even if communication can be maintained, how can the probe be positioned? Even if it can be positioned, how can its orbit be accurately adjusted to ensure that it changes its orbit when it should, and accelerates when it should?

This series of problems involves extremely profound mathematical calculations, space observations and basic principles, and is extremely complex.

But at this moment, no problems could hinder Li Qingsong's determination.

He didn't care about much else.

In an instant, hundreds of thousands of clones were drawn out. Combining his previous knowledge reserves with the knowledge obtained from interrogating the captives of the Bluetook civilization and reverse engineering during this period, Li Qingsong devoted all his efforts to the task of developing the earth probe.

The first task to be tackled was the deep space communications system.

Li Qingsong plans to deploy three large space antennas around Luoshen and Enemy Star respectively to use them to maintain contact with the probes that are about to set sail.

Secondly, Li Qingsong began to allocate manpower to carry out the manufacture of the second, third, and even the tenth space optical telescopes.

If you want to get a deeper understanding of the detailed data of the eight major planets in the solar system, an optical telescope is essential.

The third is the manufacture of the detector itself. It must not only have extremely high reliability - after all, once it enters deep space, you can no longer touch it, but also have extremely high precision and sensitivity.

The probe can only carry a limited amount of fuel, so it must be used prudently. If it wastes a little more, it may not reach its destination.

At the same time, it must be used when it is needed. The time and amount cannot be wrong at all. Otherwise, it may fly to other places.

Fourth, it is the carrier used to launch this probe.

The method of using a spaceship to accelerate it to a certain level and then throwing it out as before will not work here.

A spacecraft can only carry a limited amount of fuel, and can only provide a limited amount of acceleration.

There was no other way. Li Qingsong could only pick up rocket technology again like the human world developed aerospace technology. And not the single-stage rocket like the current interstellar missile, but a multi-stage rocket.

Only a multi-stage rocket can accelerate it to a sufficient speed to reach the earth in the shortest possible time.

Otherwise, it would be meaningless if it took decades or a hundred years to get there.

Under the premise of maintaining the normal operation and manufacturing of the base, hundreds of thousands of clones work day and night with all their efforts.

Gradually, ten optical telescopes came to the vicinity of Rosene and began to observe the inner solar system non-stop, accurately measuring the mass and density of each larger celestial body.

Deep space communication technology also made breakthroughs one after another. Finally, several super-giant antennas with a diameter of 100 meters and an area of ​​about 8,000 square meters were assembled in space.

They form a plane that is exactly perpendicular to the ecliptic plane.

Three giant antennas formed an isosceles triangle with Rosene as the center, forming an array. With the cooperation of the ground communication base, they achieved the effect of an antenna with a diameter equivalent to 4,000 kilometers.

On the enemy planet, Li Qingsong made the same arrangement, also setting up three giant antennas to form an array.

In the precision machining workshop, hundreds of clones, with the help of equipment, concentrated on making the various components of the detector bit by bit with a more meticulous and serious attitude than soldering transistors on a circuit board.

In the space factory, a super-giant three-stage rocket with a length of 230 meters and a diameter of 20 meters was slowly assembled.

Moreover, not just one, but five were built at the same time.

They have gone through multiple rounds of test runs at ground bases, but Li Qingsong is still not very confident about the overall performance.

Even humans on Earth have never built a rocket this big.

So Li Qingsong decided to conduct a test.

A total of about 40,000 tons of liquid hydrogen and liquid oxygen were poured into the huge rocket. With an ignition command, an extremely strong flame sprayed out from the tail of the rocket, pushing the giant rocket with a total mass of more than 60,000 tons to accelerate and slowly break free from the gravity of Luoshen.

But the good times didn't last long. Before it flew far, it exploded with a loud bang.

Tens of thousands of tons of liquid hydrogen and liquid oxygen turned it into an unprecedented giant bomb, like a sun, directly illuminating the dim land of Luoshen.

But it doesn’t matter, Li Qingsong still has four.

Quickly search for wreckage, analyze data, find fault points, and make subsequent modifications and optimizations...

The second rocket also failed. The cause of the failure was the failure of the second stage to ignite.

The third was also unsuccessful due to hydrogen embrittlement, which caused the fuel to leak.

The fifth rocket failed, but Li Qingsong was not discouraged. Based on his previous experience, he built five more giant rockets.

After failing three more times, he finally succeeded on the fourth try. Li Qingsong's technical accumulation gradually matured.

This fifth rocket will take on the mission of launching that small probe.

It was placed carefully on top of the rocket.

At the same time, deep space communication networks, orbit calculations, tracking, positioning and other aspects are all ready.

ignition!
