"This interplanetary flight, with our existing two ion engines as the main power, is estimated to take about 20 days each way, so the living area does have to be retained, but it is not necessary to be so large, too large a living area will produce additional unnecessary mass and increase fuel consumption. ”

As he spoke, Chu Jungui waved his hand and cut off two-thirds of the living area, and then said, "The specific design is like this......"

He picked up a pen and began to revise directly on the blueprint. The subject's precise control of the body is manifested in the blink of an eye becoming a master of drawing, and when he pulls it, it is an absolutely straight line.

Just looking at the brand-new living area, Lin Xi's face turned a little green, Li Ruobai finally couldn't help it, and shouted: "Wait, what are these long square boxes you designed?"

"Bedrooms. ”

"This thing is one meter high and one meter wide and two meters long, you call it a bedroom?

"Lie down, there's plenty of space. I can lie in. Chu Jungui looked left and right, and felt that there was no one taller than himself except for No. 4. However, the height of No. 4 is less than two meters, so it must be stuffed in.

"What's so good about this thing?"

"The structure is simple and reliable, standardized production, and then can be stacked in layers to maximize the shipment of personnel. ”

Chu Jungui immediately drew a sketch of the other side of the living area, which is actually an automatic shelf with a lattice, which can insert the 'bedroom' directly into it, which can really save space to the greatest extent. As early as the era of the home planet, people invented the container for transporting goods, which is basically the same concept.

Li Ruobai's face also began to turn green, and said, "Is this comfortable?"

"What comfort do you need?" Chu Jungui looked dazed, "If you spray hypnotic gas during the voyage and keep it at a low temperature, you can sleep for seven to eight days at a time." One sleep is enough for the entire voyage. ”

"You continue. Li Ruobai had no temper in the face of this plan.

Of course, the test subject was not completely impersonal, and a bathroom was designed. The bathing toilet and washing and changing clothes are shared with an area of four square meters and ten cubic meters of space.

This time, even Lin Xi didn't have a temper.

The vacated space was divided between the cargo hold and the fuel tank. As for why such huge fuel tanks were needed, it was quickly explained.

Unlike Li Ruobai's plan of using an anti-gravity engine to reduce the weight of the spacecraft, the method of the test subject was simple and crude: the original rocket engine was used to propel the spacecraft away from the planet.

The primitive thing of rocket engine, with the existing production conditions, can be built in a day, and it is still a complex model. With the materials in the experimental base, the production of high-energy fuel is not a problem. Chu Jungui directly tied six rocket engines to the spacecraft in one breath, abandoned two after taking off, and flew to Planet One with the remaining four.

The gravitational pull of Planet 1 is much greater than that of Planet 2, and Chu Jungui's solution to this is more rocket engines.

When they find the target ship, they will rebuild four to six rocket engines on the spot, and then all the rocket engines will be overloaded together to send the ship into space, which is considered to have completed its historical mission. Rocket engines that are scrapped will be discarded and turned into space junk.

At that point, the Winter Hunt team will return to Planet Two with coordinate data and a full tank of rare metals and fusion fuel. By the time they returned, the remaining personnel should have built more rocket engines.

That's right, Chu Jungui wants to send supplies into space with a massive number of rocket engines and assemble a new long-distance spacecraft directly in space.

This is the idea that was used by the earliest humans when they walked out of their home planet, but they did not expect to reappear in the hands of test subjects more than a thousand years later. However, the efficiency of the high-energy fuel extracted by the equipment of the experimental base is more than double that of the most efficient fuel of mankind, so the carrying capacity of the rocket engine has also increased exponentially.

Now a new high-thrust rocket can easily put nearly 100 tons of payload into orbit. The difference is that it takes only three days to build a launch vehicle at the experimental base. By the time Li Ruobai and Chu Jungui returned from Planet 2, there were at least seven or eight rockets available.

This mode of transportation can be described as economical.

Finally, the test subject finally added a somewhat technical design, which was to add a few stellar sails to accelerate in space.

All in all, in order to reach Planet One faster and more accurately, the subject cut everything he thought was useless. Li Ruobai even suspected that if it weren't for the fact that there was still a little distance between the two planets, and it would take some time on the road, Chu Jungui might even cut down the toilet.

The advantages of this scheme are very obvious, first of all, there is no need to wait for several months, at most twenty days, and the spacecraft will be on the road. Then it no longer takes a month to fly to Planet One, ten days is more than enough. When they return, they can immediately start building a new long-range spaceship, and build a temporary communication tower to notify Sheng Tang's side to respond.

Looking at the new plan that finally took shape, Li Ruobai's face was swollen red, and he held back for a long time before he said a few words: "You thing, it's too ugly, right?"

Chu Jungui's final plan was to tie a circle of small pillars to a large thick pillar, and as for the two ion engines, they were buried in the pillars and could not be seen at all.

The more Li Ruobai looked at it, the more awkward he became, he couldn't help it, pointed to the small pillar, and said, "Can't you add another one here, just fill this vacancy." ”

"Why add one? Six is enough. ”

"But seven of them are exactly in a circle!"

"Seven is not needed. ”

"Then you can make it thicker, six in a circle. ”

Chu Jungui felt that Li Ruobai was a little inexplicable, "Now the power is enough, there is no need to be thicker." ”

"Do you have to leave a space here?" Li Ruobai began to growl.

Subject is still unable to understand the inner world of a person with OCD and shakes his head again in refusal.

The more Li Ruobai looked at it, the more irritable he became, the gap was particularly dazzling, and he couldn't wait to stand up and fill the gap.

In the end, he had to look at Lin Xi and said, "Sister Xi, you decide! I can't do anything about this kid." ”

Lin Xi was silent.

Li Ruobai snorted and said to Chu Jungui: "Do you expect Sister Xi to sit on your broken spaceship?

The subject didn't speak, originally he was just giving a suggestion, and the final decision was still in Lin Xi's hands.

Lin Xi didn't hesitate for long before making a decision.

Half a moon later, a large pillar with six small pillars spewed out a roaring tail flame, slowly rose into the air, and then flew faster and faster, disappearing into the sky in the blink of an eye.

On the spaceship, Li Ruobai's face was swollen red, he waved his hand excitedly, and kept saying: "How can this be?

Chu Jungui walked over with a rectangular box, expressionless, and said, "Don't complain, go in and sleep." ”

Li Ruobai hung his head and followed Chu Jun towards the living area.

On the ground, Lin Xi stood on the top of the building, watching the spaceship go away.
