Relying on chemical fuels for interstellar voyages is unrealistic because its energy efficiency ratio is too low.

If you really want to rely on chemical fuel, go from the solar system to the nearest star system outside the solar system, the Tianyuan Four Star System, according to the results calculated by Xiao Yu, it is estimated that you will need to build a kilometer-level spaceship, and more than 90% of its space will be filled with fuel.

It can be said that controlled nuclear fusion technology is a stepping stone to open the door to interstellar navigation, without controlled nuclear fusion, relying on chemical fuels alone, Jin Ye and Xiao Yu will be confined to the solar system for immortality, and they can't get out.

"Alright, a new generation of nuclear fusion-powered spacecraft, start building!" Xiao Yu said in a low voice.

It has to be said that the world is different from the world, and people's thinking in each world is also influenced by the world in which they live, resulting in differences.

Speaking of nuclear fusion powered spacecraft, Jin Ye has already obtained controllable nuclear fusion technology for a long time, and even achieved the miniaturization of nuclear fusion reactors, but he has been unable to build a nuclear fusion spacecraft for a long time.

Among them, the main reason is that Jin Ye has never designed a nuclear fusion engine, and this is not a big problem at all in front of Xiao Yu.

It only took about a month for Xiao Yu's nuclear fusion engine technology to make a breakthrough.

With all the theoretical breakthroughs made, a new construction plan was put on the agenda.

Build an epoch-making spaceship that uses the latest technology in terms of powertrain, structural materials, and control systems.

All the construction carried out in the early days of Titan was to serve this purpose.

The huge special steel smelting blast furnace is constantly flowing with dark red molten steel.

After condensation, the molten steel will be turned into ingots for processing.

In a huge workshop, several kinds of special metal molten steel are mixed here, and after a series of special temperature and pressure treatments, the re-obtained alloy molten steel is poured into the mold at one time, which is a new alloy researched by Jin Ye based on the Edelman alloy in the Iron Man world.

This alloy is almost comparable to the Edelman alloy in terms of performance, and can be in the stars without melting, but the manufacturing process of this new alloy is much simpler than that of the Edelman alloy.

Jin Ye believes that at least for a long time, this new alloy shell cannot be replaced, even if the civilization level is improved in the future, a solid shell can be made purely from hydrogen atoms, and in terms of hardness and strength, the new alloy will not be too far behind, at most it will be a little heavier.

In order to ensure his safety, Jin Ye also spent a lot of money this time.

Xiao Yu is doing his best to build the best quality materials. These materials, after being processed, will become parts for this great, epoch-making spacecraft, the Aurora.

And Jin Ye on the side was not idle, he had time to participate in Xiao Yu's construction plan, it can be said that Jin Ye knew every detail on the upcoming Dawn, as long as Jin Ye was given enough time, Jin Ye could even rely on his own strength to independently build a spaceship with his own hands.

In other aspects, Jin Ye naturally did not delay.

First of all, in the newly opened Dao Xuan space, all kinds of spiritual fruit seeds brought from the deity have been planted.

What is the second-generation peach fruit pit, Shouyuan fruit seeds, etc., as long as these spirit fruits grow up, they will be enough for Jin Ye's cultivation.

At the same time, Jin Ye also determined his own cultivation path, which was Jin Ye's self-created martial arts method.

The reason for this choice is also simple, first of all, there is no such thing as aura in this world, and it is even more difficult to cultivate immortals in this world.

However, Jin Ye's self-created martial arts method is different, first of all, the essence it extracts comes from its own qi and blood, and it is very little affected by the environment, and secondly, this world is not suitable for cultivating immortals, and Jin Ye's self-created martial arts method is also extremely powerful, and cultivating to a certain realm is enough for Jin Ye to crisscross this universe.

Time passed unconsciously, and while Jin Ye continued to grow stronger, various components from at least hundreds of equipment manufacturing rooms were gathered in the huge assembly workshop of the main base. At least tens of thousands of robots are busy here, assembling various precision components one by one, and it takes two months to build a spaceship.

It is an irregularly shaped spacecraft with a diameter of 20 meters and a height of about 5 meters, with a nuclear fusion engine for the power system, the latest photonic computer for the control system, and a new type of Edelman-like alloy for construction.

On the side of the ship, three large gilt characters are engraved, the Dawn.

This is a spaceship that gathers all the hard work of Xiao Yu and Jin Ye, and this is the most advanced spaceship that can be made with the current technology of the two.

In order to build this spaceship, Xiao Yu and Jin Ye spent almost all the resources they had on hand.

And today, it has finally ushered in its first voyage and test.
