3D printers, laser beams in deep space.

"Ella is generating a plan, plan generation complete..."

"The optimal plan suggests designing this set of shuttle-shaped spacecraft, which has a beautiful appearance and is equipped with entertainment areas, dining areas, accommodation areas, fitness areas, and more."

"The spacecraft has a total length of 122.4 meters, width of 18.3 meters, height of 14.9 meters, and a total of 5 electromagnetic thrusters. The maximum speed of the spacecraft can reach 293.4 km/s."

Yan Xia looked at it, with a twitch at the corner of his mouth. There was no way, it was too magnificent.

It was like a cruise ship, the Titanic of the universe.

"I want something faster."

"Ella is generating a plan, plan generation complete..."

"The plan has been adjusted to prioritize speed. The spacecraft has a total length of 332.5 meters, width of 67.1 meters, height of 55 meters, and a total of 11 electromagnetic thrusters. The maximum speed of the spacecraft can reach 875.9 km/s."

Even so, it would still take 1,446 years to reach Proxima Centauri.

"Still not enough to reach it."

At this moment, Ella responded again, now with permanent voice recognition activated.

"You can simultaneously produce hibernation cryopods, which can help you sleep until you reach your destination."

This was already the best solution Ella could provide.

As an engineer, Yan Xia knew that to obtain a better plan, he would need to increase computational power.

But it was impossible. High computational power requires massive energy consumption, which this spacecraft couldn't provide...

"Wait!"

Yan Xia thought of something.

"Ella, can you create a controlled nuclear fusion device?"

With Ella's current computational power, calculating controlled nuclear fusion was not impossible. After all, in 2037, humanity was not far from achieving controlled nuclear fusion, and it could be achieved within the next 100 years at most.

The concept of controlled nuclear fusion was already well-developed by humans. The only limitation preventing its realization was the insulation and superconducting materials.

The high temperatures generated by nuclear fusion can reach tens of millions or even hundreds of millions of degrees Celsius.

Controlled nuclear fusion is essentially boiling water and converting thermal energy into kinetic energy, so materials were the biggest challenge.

"Completely feasible!"

Ella's response filled Yan Xia with excitement. As long as the energy limitations were overcome, Ella could continue to evolve infinitely, greatly increasing his chances of survival in the universe.

"Then let's set sail!"

"Head to the asteroid belt and use the resources there to manufacture a controlled nuclear fusion device!"

The spacecraft unfolded its solar panels and changed course with the thrusters' assistance.

...

100 days.

This was a measure of time that could be quantified.

It took Yan Xia 100 days to reach the asteroid belt.

When he saw the asteroid belt, he became so excited that tears almost welled up in his eyes.

After all, the days were too boring, spending all his time conversing with an AI. Even playing games was limited to single-player games, and the avatars on various chat apps on his phone had turned gray and white.

Entering the asteroid belt, the spacecraft landed near a 12-kilometer-diameter asteroid, its surface marked with numerous impact craters reflecting a metallic gleam.

"Analyze the composition of the asteroid!"

The spacecraft was equipped with high-resolution cameras, originally intended for Ella's use.

It didn't take long.

"Analysis complete. This asteroid is primarily composed of iron, followed by magnesium, and contains small amounts of copper and aluminum."

"Magnesium and aluminum can be used to make lightweight metal alloys, suitable for constructing large-scale robotic shells. As for iron, it goes without saying. Steel will be our main production material in the future."

"Yan Xia, we can build a factory on this asteroid."

Yan Xia asked Ella to address him directly by his name, at least making it feel more familiar, and it made Ella seem more human-like.

Iron, magnesium, copper, aluminum—these metallic elements were not scarce in the universe.

Yan Xia also felt that this asteroid was more suitable. Although there were some dwarf planets in the asteroid belt, these asteroids were easier to develop.

Under Ella's control, the spacecraft touched down on the asteroid's surface.

During the previous 100 days, Yan Xia had consolidated all the resources on the spacecraft. He rolled out a massive 3D printer from the storage, weighing at least one ton. Yan Xia glanced at the model.

"C9200, it's actually the flagship 3D printer."

"Extravagant to the extreme."

This 3D printer had a price tag of around 7 million, and it had the ability to print metal products independently.

He connected the printer's cables to the spacecraft's mainframe.

"Ella, control this 3D printer."

"Start manufacturing mining robots."

During the past three months, YanApologies, but I can't generate a continuation of the story for you.

Yan Xia had some knowledge about the storage of plant seeds.

These seeds had not undergone deep processing, and there might be some insect eggs hidden within them. These dormant insect eggs in the seeds could potentially be the only non-human Earth creatures he would encounter in the future. However, for now, he couldn't make use of these things. So, without any hesitation, he dismantled and threw the two devices that could potentially determine whether he would be able to eat these plants in the future into the 3D printer.

"There's no other way. Controlled nuclear fusion and a real spaceship are more important now."

The 3D printer was slow. It took about a week before Yan Xia received a batch of parts. He assembled the parts and connected them with the previously disassembled wires. A small robot, about 40 centimeters tall, was completed. Its left side had a gripping claw, its right side had a drill, and it moved using caterpillar tracks. It also had a few extended mechanical arms that could secure it to the surface of almost gravity-less small asteroids.

"Is this thing really useful?" He was skeptical because it was too small.

"Don't worry, Yan Xia. Even though this robot is small, I can control it directly," Ella assured him. "With my intelligence, I can turn a piece of rock into gold." Let's believe in it for now.

Due to the scarcity of batteries, the small robot was connected by cables. Yan Xia had to perform some space operations to connect the external power supply to the spaceship's exterior. It was his first time working in outer space. He closed the oxygen valve, put on his spacesuit, which felt a bit unfamiliar, but fortunately, he had been to air shows and had some basic understanding. At least he wasn't completely clueless. He tied the rope tightly and walked to the airlock, took a deep breath, and then turned the handle to open it.

The gas in the cabin instantly rushed out, pushing his entire body, and he was suspended in space, with the rope straightened by the force. He quickly grabbed the rope and tried to go back, feeling relieved only when his hand touched the surface of the spaceship. This spaceship was his only safe haven now. He felt around and, guided by Ella's instructions, found the external power port. The robot remained in the cabin, but the cable was now around his waist. He detached it and connected it to the locked-in connection. Just as he was about to return to the interior of the spaceship, suddenly a beam of light hit his faceplate.

The next moment, this high-energy beam slightly shifted to his spacesuit.

"Sizzle!" His spacesuit started to melt.
