The inspection of the entire spacecraft was completed. Chu Jungui looked at the huge metal bucket and asked, "What shall we do with this big guy?"

Li Ruobai was also a stunner. How can there be space on the spacecraft for this huge space jumping device? How to deal with this huge barrel with a diameter of nearly ten meters is really a hassle.

After thinking about it for a long time, Li Ruobai didn't think of a reason, and he said, "What do you think?"

"Just use it like this, anyway, it just jumps once. Are all permanent magnets used on it? Isn't it cheap to recycle them?" The test subject thought from his usual perspective.

"That's true." Li Ruobai also figured it out. But he was a little bit embarrassed and didn't know where to put the big barrel. The existing spacecraft is not big enough. If you want to stuff this barrel, the reconstruction project will be no less than a new one.

"It's simple, just solder it to our ship."

"What did you say? Solder it on?"

"Yes, like those rocket boosters."

A pattern appeared in Li Ruobai's mind immediately, and a large barrel was originally attached to a cylindrical spaceship ... This pattern immediately caused the onset of obsessive-compulsive disorder, but to achieve symmetry, it seems that a large barrel needs to be posted ...

"You don't think it's a problem. Then do it. However, the new spaceship will have more people and more supplies, and the one we have is not big enough."

The test subject set up a task and tried to solve it. The question was unexpectedly easy, and the answer came in an instant: "We can make the same spacecraft cabin and then put the two together."

"How to fight?" Li Ruobai had an unpredictable hunch.

"You can spell as much as you want, side by side, or back and forth. If you want, you can cross."

"I don't want to!" As soon as the words came out, Li Ruobai remembered that it seemed to be more symmetrical only with a cross, but it was not much better.

After calming down, Li Ruobai asked, "Why design this way?"

"Easy, cheap."

"We don't need to think about costs."

"Time is cost."

Chu Jun's return made Li Ruobai have nothing to say, and that's where the chat started.

When the two got out of the spacecraft and connected with the outside team members, they began to design a disassembly plan. At this time, the drones that have been released have returned home one after another, bringing back many useful data. The good news is that the vast majority of the resources needed in the surrounding area can be dismantled from the wreckage of the spacecraft, if not.

The next task is to distribute the task. The four need to refine enough fusion fuel, and at the same time prepare a large amount of rocket fuel and assemble multiple rocket engines in order to bring the space jumping fuel tank back.

The tasks seemed very burdensome, so the four of them started working after a short break.

Chu Jun left the camp with an off-road vehicle. This time, the vehicle was equipped with an excavation module. He drove to the mining area detected by the drone, preparing to collect fusion fuel.

This is a wilderness with patches of reddish brown soil. But the composition of the soil here is completely different from the parent star.

Chu Jungui stopped the off-road vehicle and used a personal terminal to remotely explore the machine to dig the ground and analyze the composition. He himself brought a portable rig and started drilling everywhere on the ground for inspection and composition analysis.

The content of helium-3 in the soil is quite high. Chu Jungui removed a refining furnace from the car, placed it on the ground, and then connected the refining furnace to the energy of the off-road vehicle. He put the excavated soil into a refining furnace, heated it in the furnace, and then separated the helium-3 through a series of processes.

The content of helium-3 on this planet is extremely high. Chu Jungui continuously processed dozens of furnaces to obtain a whole cylinder of helium-3.

He mounted the steel cylinder on a special condensing processor, started the condensing machine, continued to dig the soil, and sent it to the refining furnace.

An hour passed in an instant, Chu Jungui smelted 30 furnaces continuously at a speed of 2 minutes per furnace, and obtained a steel cylinder of helium-3. At this time, the helium-3 of the first steel cylinder had been processed, and was successfully pressed into a fuel box the size of a shoe box, and the box was only about a quarter filled.

This box is full and will be a full half kilogram of helium-3. This is not a small number. In the era of home stars, it is said that the world's total energy demand for one year cannot consume one thousand kilograms of helium-3.

Chu Jun turned his head and worked hard until he filled the entire energy box. Seeing the time, four hours had passed. Only the test subject can endure such a long period of repeated labor without being bored and bored.

In fact, in the past few hours, Chu Jun's return was very fulfilling. He assigned a processing unit to direct the physical work, and the rest of the computing power continued to optimize his combat components.

With the fuel box full, Chu Jun returned to his home. This kind of fuel cartridge can't be made casually, it can only be manufactured at the second planetary experimental base. They only brought four of them together this time, but did not expect Chu Jun to return and get a box.

After a while, Chu Jun picked up the equipment and returned to the car, leaving a pit in a place, probably Li Ruobai would have a headache when he saw it. Anyway, Chu Jun took a lot of photos and was ready to send them to Li Ruobai's personal terminal ~ lightnovelpub.net ~ Li Ruobai's three were not slow this time. With the example of Chu Jungui, they also learned to eliminate all unnecessary steps and work directly. When Chu Jun returned, four metal barrels had been erected around the camp. This was the new rocket engine shell. All alloys were taken from the wreckage of the 151 exploration spacecraft.

Li Ruobai refined the dismembered wreckage and turned it into a raw material for the rocket engine. Anyway, the space-jumping device containing the E substance must be taken out, and a large hole must be made in the spacecraft wreckage.

In this way, four people worked hard day by day until all four fuel tanks were filled, and by the way, the spacecraft fusion ion engine was filled with fuel, Chu Jungui joined the three and began to assemble the rocket engine.

After a few more days, four new rocket engines had been assembled, and the space jumping device had been disassembled and welded to the spacecraft. Only seven rocket boosters could be stuffed around the original spacecraft, so Chu Jun returned and tied the two boosters into one, and directly plugged into the empty space. As for the protruding one, there was no sense of violation in the eyes of the test subject. .

Then add a fairing to that space-jumping device, and everything is done.

The next day, a total of eight rocket boosters spewed flames at the same time, and the billowing smoke formed a spectacle on the planet, in contrast, the faint blue light of the ion engine was completely masked.

After eight days on Planet One, the four set out on their way home.

This time Li Ruobai said he would not enter the box bedroom again, and stayed in the cab with Chu Jungui. It was only on the third day that he couldn't resist the boringness of the long journey, especially Chu Jun returned to talk one after another. As long as he doesn't speak, Chu Jungui can remain silent for a whole day, looking out of the window.

Li Ruobai didn't understand, what are the good looks of these starry sky.
