In the second half of the month, Nana took over the production and operation of the base, and at present, except for food cultivation, energy harvesting, ore mining and base expansion, the rest of the area in the base is in a state of shutdown to save consumption.

Cao Chuan's room.

"The core purpose of the return to the earth plan is definitely not to get manpower, but to get a batch of materials for the final improvement of the base's production system, otherwise, even if you hire a younger brother, you will still face the dilemma of poor production conditions and a confused future, resulting in unpredictable risks."

"The materials to be obtained at the core include: the relevant components of the unmanned unit, so that the scale of the unmanned unit will be repeated several times in a short period of time; Various types of processing and production equipment to further improve the industrial production system of the base. With the above materials, on the one hand, the productivity can be further expanded, and on the other hand, the technical level of the entire base will be improved by hundreds of years, and the modern level will be fully reached. ”

"Considering the complex environment of the home planet and what I have to do, I have to conduct a psychological, sociological, and hacking simulation of the rules to prevent me and my attempts from being discovered.................. The rule simulation was in progress and took 421.6 seconds.................. The rule simulation was in progress and took 610.1 seconds.................. The rule simulation was in progress and took 555.0 seconds. ”

"Well, when the time comes, disguise, use a new identity, speak an authentic Chinese, and then use hacking techniques to eliminate your chat records, travel records, and transaction records, avoid being tracked by providing a fake IP address, and find a way to find a place that the five hooligans can't manage, and the probability of problems will be greatly reduced."

"Then there is a spacecraft to the earth because the take-off point is on the moon, and it is not difficult to focus on solving the ultra-high temperature that passes through the atmosphere."

"The process of raising supplies to get back to the lunar base will be a daunting challenge, I will have to build a truly usable rocket to achieve my goal, make sure that no one is detected in the process, and solve the problem of money and prohibiting the export of technology."

Although Cao Chuan has come up with a complete set of plans, there is only one direction, and there are still many problems to be solved.

Cao Chuan first found out the return vehicle left by the Lighthouse Country at the lunar base, conducted an inspection, and mastered how to use it.

"It is worthy of being the overlord of the Beacon of Freedom, the return to the ground is exceptionally perfect in terms of craftsmanship and performance, and even I can't find any problems before the rules are simulated, and even the fuel reserves are enough to set off now. However, if you return to Earth empty-handed, isn't it the same as starting from scratch again? ”

If he had found the Earth Returning Vehicle a few months ago, and he had not yet made up his mind at that time, let alone discovered the special abilities he had, he would definitely have made a choice without hesitation, no matter what would happen later, it would be best to return to Earth.

Now, Cao Chuan has to work hard to realize the great cause in his heart, and he will definitely not act rashly.

He held his chin: "Anyway, considering the predicament that will be encountered on the earth, if there is a way to bring some souvenirs back, it will help raise some of the money." ”

"Nana, unfold the map of the moon."

Cao Chuan stared at the map presented on the screen, thinking about what good things could be sold for money.

"There are a lot of conventional resources on the earth, and they are not easy to bring, and they can't be sold for any price."

"As for the rock samples unique to the moon......." he opened Taobao, searched for it, and nodded, "I can barely sell it for some money." ”

Looking around, within a few square kilometers controlled by the lunar base, he thought about what other specialties there were, and after ten minutes, his eyes fell on a place, the Quiet Sea, one of the most well-known Moon Seas on the Moon.

A solitary Star-Spangled banner standing on the moon, symbolizing the glory of the past, is one of the only relics of the Apollo moon landing program of the Free Lighthouse Nation half a century ago.

A footprint deep into the soft lunar wilderness, a small step for humanity, a giant leap for civilization, is also one of the only relics of the Apollo moon landing program.

"I've decided, take these two things with me." Cao Chuan's eyes lit up, he stood up, put on a spacesuit, brought some supplies, and drove a mining vehicle to the location of the map.

Fortunately, the Lighthouse Nation did not set up the lunar base too remotely, and it didn't take long for him to arrive at the designated location.

Instead of starting work immediately, he first stood in front of the flag, took a selfie with his camera, and then put his foot next to Armstrong's footprints, and then he reached out and pulled up the lighthouse flag fixed on the ground, took out his tools, and picked up a half-meter square piece of earth and stone near the footprints, and packed it away.

On the way back, I found a few minerals that can only be found on the moon by identifying minerals, and collected some of them for preservation.

"I can get enough money this way, relying on the productivity of the whole earth, and my rule simulation ability, it is possible to build a rocket to return to the moon!"

Cao Chuan finished the preparations, loaded the supplies he was going to bring back, and gave Nana a final order to take care of the operation of the base.

"Roger, master." Nana replied calmly.

Then wait patiently for the right launch time, and the re-Earth vehicle will officially set sail.

The first space trip, the result was from the moon to the earth, which couldn't help but make him feel embarrassed, and when he thought of what he was going to do when he went back, Cao Chuan was still full of ambition.

It took the vehicle a day to break free from the weak gravitational constraints of the Moon and reach the Lagrange point between the Earth and the Moon. It's a great place to see both the Moon and the Earth in its entirety, and the other planets of the solar system are also quite noticeable because they are not blocked by the atmosphere.

Then taking pictures, Cao Chuan calculated his current position, as well as the movement of the earth, so as to facilitate his entry into orbit.

A few minutes later, the side nozzle of the returning vehicle spewed out a thin air flow, slowly turning the direction closer to the earth, the closer to the earth, the greater the gravitational force, the faster the speed of the aircraft, until it was completely captured by the earth's gravity, without the centrifugal force brought by the revolution of the first cosmic speed to maintain balance, the aircraft instantly turned around and began the most thrilling landing.

300 kilometers from the earth, you can vaguely see the satellites floating in the distance, rocks, the International Space Station, as well as the brilliant auroras over the polar regions and the colorful clouds on the continental oceans.

As the aircraft approached to 100 kilometers, the terrifying speed made Cao Chuan feel breathless.

The temperature of nearly 10,000 degrees Celsius generated by the intense friction between the densely dense atmosphere and the front end of the aircraft still makes people feel that the aircraft will disintegrate anytime and anywhere, even if it is protected by heat protection tiles.

The aircraft is getting closer and closer to the earth, Cao Chuan started the reverse nozzle to slow down, and then unfolded the parachute, which lasted for more than half a year to live in a low-gravity environment, so that his physical fitness decreased significantly, and at this time he was even more overwhelmed, Cao Chuan insisted, after a few minutes of waiting, the aircraft fell into the sea with a bang, and finally completed the landing and returned to the earth.
