In the end, Bai Kaixin still didn't tell Yun Yi anything about the Dark Ages, and no matter how much Yun Yi asked, he didn't say a word. He and Syrumis originally came to the base to look for Yun Yi, and Bai Kaixin wanted to know if Yun Yi had the same problem of advanced martial arts cultivation and lack of skills as Syrumis. It's just that after seeing the robot, Bai Kaixin is no longer in the mood, and then returns to the Aquarius ship with Syrophis.

"Dark Ages...... Robot? What is the connection between the two? ”

After thinking about it for a long time, Yun Yi didn't analyze the answer. At this point, Aurelia walks over and tells him that both ships are loaded with robots and equipment and are ready to go.

These two ships are two of the only three ships that Cloudwing has now besides the Aquarius. The Isselas standard ship was extorted from the rebels when they left the capital, and although it was a little dilapidated, and the engine was scrapped due to overuse during the last escape, it was barely usable after a simple repair on the Aquarius. The only way to fully restore the broken parts is to wait until the shipbuilding plant at the base is put into operation before replacing the broken parts. The other cargo ship, as well as the small warship docked between the base and the ship, were captured by Yunyi and the other prisoners when they left Poloni.

After Yunyi boarded the ship, Aurelia gave an order, and the two ships slowly left the base dock and flew towards another celestial body not far away.

The planet is about the size of the moon, Earth's moon where humans originated, and its gravitational pull is only one-eighth of that of standard gravity. In other words, if you can jump one meter high on earth, you can jump eight meters here. The planet contains a large amount of helium-tribal, iron, nickel, manganese, carbon and other mineral resources, as well as a small number of rarer mineral deposits. Helium-3 can be used as fuel for the nuclear energy base, and other deposits will be smelted and processed to become the alloying material widely used in the base, which can be used to produce robots, build equipment, and the main structure of the spaceship. However, if you want to build a spaceship, you have to go to other celestial bodies to mine other mineral resources before you can make high-strength alloy materials for the outer armor of the spaceship and mechas.

After more than two hours of sailing, the spacecraft landed on the planet named Mine Zero Zero.

The temperature of the celestial bodies in the star belt is generally very low, so the main material of the robot is made of low-temperature resistant alloys, and there is no concern about problems. It's just that at such temperatures, fighters who lack spacesuits can't survive. After the two spaceships landed, Aurelia sat in the spaceship command room and ordered the cabin to be opened, and countless robots walked out of the spaceship in a neat formation and stood by outside. At the same time, a large number of equipment and components were put into the vicinity, which were used to build nuclear energy bases and mining plants.

The technology needed for a nuclear energy base is found in the Aquarius, and after a simple modification of the Cloud Wing, it is very suitable for operation on this planet.

After the robots received the order to start work, they quickly moved. Countless materials are transported by robots to the vicinity of the selected location, and at the same time, a large number of engineering robots begin to level the surface of the location. The efficiency of the robot is extremely fast, and after half an hour, thousands of square meters of flat ground have been sorted out. As Aurelia gave orders one by one, another robot carrying ordinary alloy steel plates began to lay on the ground. Another robot drilled a deep hole tens of meters deep and half a meter in diameter in the leveled ground, and drove solid alloy steel columns into the ground to fix the base.

During this period, Yun Yi and Lorraine were not idle.

Lorraine has been in the command room to help Aurelia control the robot, and although Aurelia is the commander, she doesn't know much about engineering. Although there is already a corresponding program for how to install it, it has also been carefully calculated by [Sakura]. However, with Lorraine by her side, Aurelia was not confused.

As for Yunyi, when the spaceship landed on this planet, he drove out in his mecha, in order to thoroughly discover the mineral deposits on this planet.

In the past, microrobots have been used to detect surrounding stars. However, due to its small size, the microrobot cannot be equipped with better detection equipment, so it can only be probed. And Yunyi this time, it is to carefully explore this planet in order to facilitate the layout of the mining plant in the next step.

……

When five hours later, the tired cloud wings flew around the planet and returned to the ship, there was already a huge building more than ten meters high and an area of 1,200 square meters. The entire structure is made of alloy steel, and although the strength is not as strong as the outer armor of a battleship, it is about the same as the main steel frame of a spaceship. The materials were all brought from the base, and the two ships returned to transport the materials once before the metal structures were transported.

And this is only the initial form of the energy base.

When the mining and metallurgical plant is put into operation and produces enough alloy steel, the base will be expanded.

This is a nuclear energy production base, and although the exterior has been completed, some of the sophisticated equipment inside is still being installed. Except for a small number of robots working in it, most of the rest of the robots drove to the nearest area with a relatively rich helium-3 resource and began simple mining. Only when you have energy can you smelt and provide high energy blocks for your base. These things must be done one by one, step by step, especially at the beginning, and must not be sloppy.

"Boss, you can take a break for the time being." Seeing Yun Yi coming back, Aurelia rubbed her somewhat red eyes and stared at the screen for a long time, even Aurelia couldn't stand it. "Now it's the delicate installation of several nuclear power furnaces, everything is going according to the procedure, and we don't have to meddle," she said. It is expected to take more than 10 hours to complete. ”

"Well, you can take a break, don't get tired." Yun Yi said soothingly, and then asked, "What about Lorraine?" ”

"He's staring at the construction of the mining plant in the machine room over there, and it's probably almost finished."

Yun Yi nodded, the construction of the mining plant is not difficult, as long as a small base is built on the ground, the next task is to go deep underground, the technical content is not high, even if no one is watching, [Sakura] can easily control the robot to complete these tasks.

Aurelia stretched, her face tired, but her spirits were good.

"Boss, are you leaving?"

Just as Yun Yi was watching the installation progress on the screen, Aurelia's voice suddenly came from behind him.

Yun Yi didn't look back, but answered, "Yes, you know the purpose of my coming to Iseras, which is to bring you all back to Berwick. It's just that you don't want to leave, so I have to go back by myself. After a slight pause, Yun Yi turned around and looked at Aurelia's charming eyes: "Xiaoya, come back with me." Leave the work here to Guyi and Lorraine, you don't have to stay here. ”

"Without my rebels, would they still be rebels?" Aurelia smiled at him, "If you want to go, just go, as long as you can remember that there is someone silently missing you in this inaccessible place when you are fine." ”

"Xiao Ya......" Yun Yi called affectionately.

Aurelia gave him a blank look: "Just kidding." Our relationship is just a deal! Do you understand the transaction? Sister, I sacrificed my body in exchange for your support for the rebels, it seems that this business is very successful, hehe, I actually got such a good base, so many robots and all kinds of technology. Boss, you are too generous, you even left the technology of the Wumu-class battleship and the God of War mecha. Aren't you afraid to wait for me to become strong and rebel against you? ”

"You're not that kind of person...... Yun Yi said with some sorrow: "Xiaoya, you tell me, in your heart, I ...... Who the hell are you? ”

"Who? The boss, of course. Aurelia stretched and glanced at him amorously, "You provide the technical equipment, and I'll help you cause trouble behind Iseras." On the day Isselas is overthrown, all you have to do is help me rescue the royal family of Hilphaster. Then I don't owe you anything, and you don't owe me anything...... Ah, I almost forgot, you have to give us a piece of land to recuperate, and don't break your word when the time comes. ”

Seeing that Aurelia was unwilling to talk about the emotional aspect at all, Yun Yi could only say helplessly: "Don't worry, I won't forget it." ”

Then, there was a dead silence.

"Yo, boss, you're back."

What broke the tranquility was Lorraine, who had just come out of the computer room next to him, wiping the sweat on his forehead, while lying on the sofa in the command room without any image, panting and saying: "I only learned today that it turns out that non-stop typing on the keyboard can make people so tired." ”

"The mine is finished?" Aurelia asked coldly.

"It's done, it's done." Lorraine exclaimed excitedly, "The digging has begun." Hey, boss and boss, do you want to take a look, those robots are digging up mines so fast, they're superhumans. As soon as the two arms of the mining robot turned, a large pile of ore fell to the ground in a hurry, and was transported to the next transportation channel by the device of the robot's legs, and the whole process did not take even a second. Watching the amount of ore in the warehouse skyrocket, it's a great sense of accomplishment. ”

Yun Yi smiled: "This is just the completion of the first mine, and there are still four mines and smelting plants to be built in the first stage, don't feel too easy." ”

"Don't worry, boss, with the help of the robot and Sister Sakura, I didn't do anything at all, just to correct the deviation. It's easy, boss, and I'm here to assure you, in three days at most, the rest of the factories will be completed, and there will be no problems. ”

"Okay, I trust you."

After Yun Yi finished speaking, he looked at Aurelia again and said, "By the way, I have to leave for the next three days, and the construction of this side of the base will be handed over to you." ”

"Where are you going?"

Yun Yi smiled slightly: "Solve the population problem of the base......"
