Since Einstein broke the concept of absolute mass and absolute energy and came to the conclusion that mass and energy are interchangeable, human research in this area has not stopped.

The atomic bomb and the hydrogen bomb are the most haode proof. To put it bluntly, nuclear fission and nuclear fusion are just a way to convert mass into energy, but the conversion efficiency of nuclear fusion is a little higher.

For this kind of research, Xiao Yu can be regarded as standing on the shoulders of giants, with the research results of all mankind as a reserve, and on Jupiter, the personal teaching of the great natural teacher, Xiao Yu is very confident in breaking through the jishu barrier of controllable nuclear fusion.

Five hundred kilometers away from the base, Xiao Yu rebuilt a small base and used Fengshen 1 to transport fifty specially made robots here for research purposes.

This is a specialized institute for controlled nuclear fusion. Although Xiao Yu already has a lot of confidence in mastering this jishu, he still has to make some risk estimates, if the fusion reactor explodes, it is not a joke, such a power may be able to wipe out the base that Xiao Yu has worked so hard to build in one fell swoop.

Taking out the raw materials such as deuterium and tritium that had been prepared long ago from the old spaceship, Xiao Yu began intense research.

At the same time, in the other direction, which was nearly a thousand kilometers away from Xiao Yu, in the long dark night, a bright spot suddenly appeared, then a second, a third, a total of seven.

This is a prospecting squad. The seven robots were armed with enough equipment to conduct field reconnaissance of a rare earth mining area here.

Behind the robot formation, a strange plane in the shape of a semicircle let out a roar, and after a powerful air flow erupted from the bottom, the entire plane quickly took off and flew towards the base.

This is the Fengshen 1, which has completed the delivery task, and has returned home.

On the ground, in the darkness, only seven lonely robots remained, walking forward step by step with strange steps.

Xiao Yu divided his spirit into hundreds of millions, and through the night vision devices of seven robots, he was paying attention here.

The ground is still gentle, with little undulation, and the terrain here is basically the same as the rest of Titan.

A robot slowly bent down, the searchlight above its head illuminated the ground brightly, and a large area of orange-red ground was photographed and sent to Xiao Yu's head through the satellites in the sky. Xiao Yu gave the next action order.

The robot stretched out its right hand, and a shovel poked out of its palm, scooping a shovel of dirt on the ground, and then, with its head up, emitted a strange red glow in its eyes, and began to analyze the objects.

The other six robots went in other directions and dispersed. One of the robots stopped after a kilometer, then crouched down, sticking a drill out of its arm and digging into the ground.

Xiao Yu was staring at this place tightly.

The drill is getting deeper and deeper. One meter, two meters, three meters......

It stretched to five meters underground before stopping. Then, the robot began to slowly lift the drill out.

At the bottom of the iron drill, some samples taken from five meters below Titan have been contained. The robot also leaned its head up, and its eyes began to glow with a strange red light, and began to analyze the minerals.

At the same time, Xiao Yu, who was a thousand kilometers away, had already obtained these data in real time.

The field survey lasted two days, and the seven robots surveyed a total area of about five kilometers. Synthesizing the data obtained by the seven robots, Xiao Yu took a breath softly: "This is, this is a rare bonanza, the reserves are so rich, and it is easy to mine, such a vein is rare on the earth." ”

Moreover, the most important thing is that not far from this vein, there is a methane lake that is not too big or small, which means that Xiao Yu can get energy supplements nearby, and he only needs to replenish oxygen here regularly. Such conditions are really unique.

This result made Xiao Yu very happy.

Even, this result made Xiao Yu immediately make up his mind to build another industrial base in this high-quality rare earth mining area.

Xiao Yu is rich now, and it is not the same as the time when he wandered in the starry sky. With almost unlimited energy on Titan, and high-quality metal veins in the open air, there is no need to worry about the source of energy or materials, and building an industrial base is a matter of time.

The main base is the No. 1 base, the Institute of Controlled Nuclear Fusion is the No. 2 base, and here, the No. 3 base.

During this time, ten more robot production lines were launched, and now, more than 70 robots are born almost every day. If it weren't for the scarcity of some metal raw materials, Xiao Yu could even increase this production rate to more than 120 units per day.

Of course, this "day" refers to the time on Earth, and the day is twenty-four hours. You can't forget your roots, even if you leave the earth. Xiao Yu said.

"For the sake of this vein, we had to suspend the manufacture of the rest of the less important equipment...... Well, we have to design and manufacture some special mining equipment for this rare earth mine. Also, there is no iron ore there, and building materials for various factories must be prepared. ”

Xiao Yu laid out a timetable and prepared to complete all preparations in two months.

The machines roared, the robots were busy shuttling, and countless strange machines were created, converging on a temporary storage point on the outskirts of the base.

Fortunately, Xiao Yu is now a shotgun, and with the strong computing power provided by the photonic computer, Xiao Yu is not crushed by these huge computing data.

In the huge computer room, countless red or blue indicator lights are constantly flashing, and the faint white mist that is constantly floating out of the liquid hydrogen cooling pool proves how much heat Xiao Yu's brain has at this moment. There are at least dozens of robots shuttling around, busy handling all the daily tasks.

It took two months for Xiao Yu to complete all the preparations. In the temporary storage point of materials, there is a large group of robots lined up in a neat line, pulling all kinds of simple board trucks, on which countless materials are stacked, as well as large machinery.

"Rare Earth Expeditionary Corps, let's go!" At this moment, Xiao Yu shouted a slogan unusually heroically.

The so-called Rare Earth Expeditionary Corps is composed of 1,000 robot units including construction robots, mining robots, flamethrower robots, maintenance robots and other robots, as well as various rare earth mining equipment, a lot of building materials, and the Fengshen 1 helicopter. Because the amount of materials was too large, Xiao Yu could not use Fengshen No. 1 to transport them, so he simply formed a team known as the Rare Earth Expeditionary Corps, which was actually a group of transport convoys. The Fengshen 1 helicopter took on the role of navigator.

As Xiao Yu's order to set off was given, a thousand robots took steps at the same time, pulling the board car behind them and starting to move forward. Large machines on wheels set themselves in motion, following closely with the troops. There is also simple computer equipment installed on it, and under Xiao Yu's control, you can go wherever you want, which is extremely convenient.

The huge legion set off, and under the dust, it looked like a group of refugees fleeing. Xiao Yu was a little dissatisfied with the flying dust, because it was a little different from the magnificent scene he had conceived in his head.

"A small place is a small place, where can it be compared to the earth." Xiao Yu pursed his lips and began to prepare for the next batch of supplies to transport the troops.

In this unit, almost every robot pulls tons of supplies. It's unthinkable on Earth, but here's Titan, where gravity is less than one-sixth that of Earth, and where everyone is a Hercules.

Dozens of flamethrower robots carrying heavy and strange-looking canisters and huge flamethrowers in their hands kept shooting at the ground with their flamethrowers in front of the troops, evaporating all small lakes of liquid methane and opening the way for the large troops behind. Overhead, the Fengshen No. 1 helicopter, which was full of science fiction atmosphere, hovered at low altitude, constantly roaring, and under Xiao Yu's control, guiding the direction of this unit.

Huge robot troops are moving forward in an orderly manner, and the rain can't stop them, the wind can't stop them, and the darkness can't stop them. The Rare Earth Expeditionary Corps is firmly moving forward, vowing to use the light of technology to illuminate this dark corner of the solar system.

They advanced at a speed of about twenty-five kilometers per hour. As long as there is enough energy, they don't need to rest. At this rate, they will be able to reach their designated location in about two days.

Due to a small mountain range and a large lake on the way, the rare earth expeditionary corps had to make a detour and delay a little, but even so, it reached this rare earth vein forty-seven hours after departure.

At this time, it happens to be the dawn of the rare earth mining area. Faint sunlight travels 1.7 billion kilometers and penetrates Titan's thick atmosphere to hit the Rare Earth Expeditionary Corps.

In the middle of the dawn, on a field of orange, stood a thousand robots, as well as countless supplies and countless heavy machinery. Overhead, the huge Fengshen No. 1 helicopter kept circling, searchlights arrogantly strafing everywhere, until it was confirmed that the rare earth expeditionary corps had successfully arrived at its destination, and then let out a low roar and flew away.

The sun reached the middle of the sky, and it was already noon. After resting and checking, a thousand robots and various machines began to get busy.

The construction of the No. 3 base began.
