Ruan Lin saw that the familiar ground was gradually moving away from him, and the surrounding snowflakes fluttered towards the windows on both sides of the elevator at a rapid speed. The lift cabin will climb at a speed of 800 kilometers per hour, which is 222 meters per second.

Five minutes later, Ruan Lin looked at the surface again, at this time he was already 66.6 kilometers above the surface, at this altitude, Ruan Lin could already see Europa's planetary curvature, he also looked at the countless bases and robots on the surface, Ruan Lin also saw the Titan in the distance.

Fifteen minutes later, Nguyen Lam was 199.8 kilometers above the surface. Once again, he saw the white-blue ice and red rust spots on Europa's surface, and he saw the 201-kilometer-high ice fountains in other locations, as if they had met for the first time.

Ruan Lin sat in the cabin: "At this time, a classical piano song, accompanied by a glass of wine, is really rare!" ”

Unfortunately, now is not the time for material satisfaction.

Even a climb of 800 kilometers per hour takes up to 20 hours to reach the top of the elevator, a process that is extremely time-consuming and uninteresting.

"A space elevator is still too inefficient. It seems that WIT still needs to capture as many asteroids as possible, and the stock of materials is still not enough. At least four space elevators to be built! It's no problem to wait as long as you want on Europa. ”

This is simply unimaginable on the earth in the past, and no country can afford the financial, material and human resources consumed by the four space elevators.

These twenty hours were extremely boring, and Ruan Lin still transmitted his consciousness back to the computer from time to time.

The space elevator stopped suddenly, and Ruan Lin looked down: the surface of Europa was visible, and to the left, Jupiter occupied more of the field of vision, and even here, the demon's eye on its surface could be observed. And at this moment it also forms a subtle orbital distance from the sun, and the sun's light shines almost all of Jupiter, and the edge of Jupiter is illuminated red by the sun, leaving only a little light in the corner to shine on Europa, which is like the last dawn.

And at this end, there is still nothing around at the moment.

"Wit, start descending, it's time to go back."

Ruan Lin's consciousness returned to the calculations, and he discussed with WIT the next material collection and the construction of the other four space elevators.

They had to be not too far apart, and their main role was to create a spacedock.

At this time, more than three years have passed, and under Ruan Lin's instructions, countless space operation robots have been produced one after another, and 130 meteor-class destroyers have been built on the surface, all of which are 30 meters long, similar to the Titan. The tonnage reached 112.5 tons, and the overall appearance was grayish-white.

But only such a small piece can be made on the surface.

Equipped with the latest laser weapons, controlled fusion engines, and centrifugal force-making devices, these meteor-class destroyers are not equipped with EMP bombs, as there are only a few dozen of them.

Several other space elevators have also stood on Europa's surface. At the top of them, the spaceyard is connected, and its general keel has been erected, and the next step is to start the official construction.

Nguyen Lin envisioned that the construction of the space dock would take three years, and the construction of two more comet-class warships would take one year.

Ruan Lin suddenly remembered a game he had played on Earth when he was a child.

Three years and three years, if Ruan Lin remembers his age, he is already 33 years old.

But it's impossible to remember the little thing like a birthday when you're busy all day.

At this time, the number of meteor-class destroyers on the surface has reached 280, and if it were not for the shortage of materials, this number could have doubled.

And the highlight of the day is the day of this spaceyard operation. Ruan Lin named it "Hope", which carried the hope of Ruan Lin's subsequent development.

Its length has reached a staggering 2 kilometers, which requires the height of two and a half Burj Khalifas on the planet.

At its widest point, it is 700 meters, and its overall appearance is cross-shaped, and the overall paint is black. It is equipped with two docks on the left and right for the manufacture and repair of ships. Fixed laser turrets were set up on the front and rear. This is like a close defense gun, just to prevent enemy ships from getting too close.

Nguyen Lam also installed two mobile laser weapon launchers on top of it, and due to the huge size of the dock, the lenses of both launchers reached a radius of 100 meters. They have a range of up to 8000 km. This is the main force of long-range strikes.

Its controllable fusion engine is also too large to propel such a huge dockyard forward.

In the final year, two Comet-class destroyers were also built by the USS Hope, 600 meters in length and 200 meters wide at its widest point, with a streamlined overall appearance and a pure white exterior paint. They are also equipped with short-range jump engines and electromagnetic pulse bombs.

Ruan Lin named them "Photon" and "Quantum" respectively.

Ruan Lin knew that this was the time to part.

"The last thing we have to do is collect as much material as we can, and then we're going to leave the solar system." Ruan Lin said.

Half of Europa's robots made it to the dock of Hope, and the rest went to various ships.

"I finally don't have to keep them this time. We were able to pack them all up and take them away. Ruan Lin said with a smile.

"Except for the space elevator." Wit's joke amused Ruan Lin too.

"Goodbye... Europa. 400 Meteor-class destroyers on the surface. and Titan, which began to initiate controlled nuclear fusion reactions. ”

Ruan Lin could manipulate any of them, or all of them, as he pleased.

Nguyen Lam decided to directly operate 401 ships for the first time.

"The standard time for controlled nuclear fusion has arrived, ready for ignition."

I saw that the tail of 401 warships spewed out plasma sparks of tens of meters at the same time, and their ignition time was almost simultaneous.

"Climb, speed: forward three."

The 401 Meteor-class destroyers unfolded in a single plane, preparing to break through Europa's atmosphere and join the geostationary orbit of Photon, Quantum, and the spaceyard.

All the fleets quickly converged, and Ruan Lin transmitted his consciousness to his body and sat down on the captain's chair in a dignified manner.

Through the small surveillance devices on both sides of the Titan, only he knew how blood-pumping this moment was.

This was the prototype of the human fleet. Earth civilization finally has a fleet of space civilizations!

Ruan Lin planned that the next three years would be the last collection time before leaving the solar system. All materials must be received correctly! Other galaxies probably don't have as many resources.

At this time, it had been three years since Ruan Lin left Europa. All kinds of materials in the solar system have been collected to the full capsule. All ships are refueled to the top.

Almost simultaneously, all ships were heading below the ecliptic plane of the solar system.

"Earth, the solar system.

Goodbye, goodbye..."

Ruan Lin looked at the bright deep sky:

"Target: Centauri α star system. Speed: Forward four. ”
