I have a space station

“Finally reached Level 4!” Dongfang Chen exclaimed.

A year! It took over a year to upgrade the space station from Level 0 to Level 4.

Level 4 is a dividing line.

Before Level 4, the space station could only be considered a miniature space station, its purpose solely to provide the necessary conditions for building a large space station later on.

“Commander, the space station has met the upgrade requirements. Do you want to upgrade?” Xiaolin asked.

“Upgrade,” Dongfang Chen said.

“Okay.”

“System upgrading, please wait…”

Since the ground operations are currently being handled by the supercomputing center, the space station's upgrade will not cause any interruption to ground services.

Half an hour later, the system upgrade was complete.

As before, the space station's upgrade only involved adjusting the pointers of the program valves. After the upgrade, only the core module and the power module had their functions released, increasing their level to 5. The other modules did not undergo any adjustments and remained at Level 4.

“Commander, the core module needs to be expanded, otherwise it cannot be upgraded again. Do you want to start building a new core module?” Xiaolin asked.

“Start it,” Dongfang Chen said.

“Okay. Do you want to synchronize the upgrade tasks for the other modules?” Xiaolin continued to ask.

“Synchronize them!” Dongfang Chen said.

“Okay. The instructions have been issued,” Xiaolin said.

“Why does the construction of the core module take so long?” Dongfang Chen was very surprised when he saw the estimated time displayed on the screen.

It showed: 43 days.

In his impression, with the current number of Worker Bee robots, building a new module should only take a few days at most.

“Commander, the new core module is larger and requires more raw materials,” Xiaolin replied.

“Then, if all the Worker Bee robots are used to build the core module, how long will it take?” Dongfang Chen asked.

“It is estimated to take 21 days,” Xiaolin replied.

“Then let's do that. Suspend the other tasks. Use all the Worker Bee robots to build the core module,” Dongfang Chen said.

“Okay, Commander, the instructions have been issued,” Xiaolin said.

“Now that 20 settlements have deployed signal towers, they have the prerequisites to provide basic communication services. Xiaolin, design a mobile phone that can use the signal towers for communication, based on the style of our early human candybar button phones. Imitate the previous mobile communication providers and integrate the chip onto a SIM card,” Dongfang Chen said.

“Commander, wouldn't it be more convenient to integrate the chip inside the phone? Why produce a SIM card separately?” Xiaolin asked.

“You don't understand this, just do as I say,” Dongfang Chen said.

“Okay, Commander.” Xiaolin didn't ask any further.

“Commander, the first fully automatic amphibious harvesting and feed processing aircraft has been assembled.” Following that, Xiaolin reported another message.

“Great, I'll go take a look!” Dongfang Chen was overjoyed.

This was going to be a major money-making machine for a long time to come, and he had to pay close attention to it.

The aircraft was already parked in the base's underground hangar.

Looking at it, the size of this harvesting aircraft was much larger than his plane. Moreover, several mechanical arms were integrated in the four directions and the top of the aircraft. The shape of each arm was different, probably designed to perform different operations.

The overall shape of this aircraft was a rounded cuboid, with a length of nearly 50 meters and a width of about 20 meters. Without wings, it looked very bulky. In the four directions, front, rear, left, and right, of the aircraft, there was also a lateral thruster each, in order to maintain the stability of the aircraft as much as possible when harvesting or hunting large animals.

Including the dozen or so landing gears responsible for support at the bottom, its overall height was 15 meters.

Dongfang Chen could understand why this aircraft was built so large. That was because it also integrated a fully automatic feed production line.

The reason why Dongfang Chen designed it this way in the first place was to simplify the process of hunting insects and fish as much as possible. If a batch was salvaged, it would be really troublesome to transport these corpses back and forth. It not only wasted time, but also increased operating costs. The chamber of commerce would have to have someone specifically responsible for recycling it, right? A special feed production warehouse would also have to be established, right? After the feed was produced, it would have to be sold, right? Just thinking about it was troublesome.

So, what feed to sell? Just wasting effort.

Therefore, he made a decision to sell the aircraft directly and earn the money back in one go.

As for the matter of producing feed, let those who want to do it do it, he said he was not interested.

Lowering the ramp, Dongfang Chen entered the interior of the aircraft.

It was quite spacious inside, like a very large office. A circle of consoles surrounded the perimeter, with a total of 16 seats. Each seat was equipped with a seat belt and a fixed rod to ensure that the staff would not be thrown out during rapid flight. Each seat had three screens directly in front of it, probably to facilitate the display of different information.

These seats could be rotated 180 degrees. This made it easy for everyone to look at the screen to work, or to turn to the middle and discuss things face to face.
