My brother is so cunning.

Earth, the netherworld.

On this plain, which has been dead silent for who knows how many years, the noisy and harsh construction noises echo.

The construction team of the Ultron Robot is building a large-scale comprehensive base in full swing.

According to the design drawings, this base is huge, almost a replica of the Jinling Xianzong base, and all the factories and facilities in the Jinling Zong base will be copied exactly.

At present, the Ultron robots are building mines, metallurgical plants, nano-unit manufacturing plants and robot manufacturing plants.

There is no lighting equipment installed at the construction site, but the robots work in an orderly manner in the dark, and buildings are rising from the ground, and equipment is installed one by one.

Wen Rui was also helpless. He wanted to follow Luosha to the evil demon domain for an inspection.

But knowing that she was a little princess on the run and had caused such a big mess in her hometown, he could only give up for the time being.

If Luosha was just an ordinary witch, with the strength of the two, there would be no risk in running around in a low-key manner.

But she was a little Raksha princess who escaped from marriage and stole the treasure of the tribe. The situation was completely different.

Both the Raksha and Asura tribes designated her as the most wanted criminal. Going to the evil demon domain with her was equivalent to being enemies with the two strongest demon tribes in the domain at the same time.

Wen Rui was made of iron, how many nails could he hammer?

Before making full preparations, he dared not set off rashly.

During this period, Wen Rui first forced the Raksha woman to teach him how to use the banana fan, and then began to smuggle robots, supplies and equipment to the earth like ants moving houses.

As long as the correct control formula of the banana fan is mastered, monkeys and pigs can use it at will.

This is also one of the characteristics of the innate treasures created by heaven and earth. It does not need to recognize the owner, and there is no spirit. Whoever is lucky enough to get it and figure out how to use it will naturally become the owner.

On the contrary, there are many restrictions on the use of artificially refined acquired treasures, just like setting a personal password. If it is not recognized by the manufacturer, it cannot be used even if it is snatched.

With the isolation of the Yin-Yang barrier, the spacecraft equipped with the curvature engine cannot reach the boundary through the jump even if it obtains the coordinates of the boundary.

Wen Rui can only fan out the tunnels between the two realms and act as a porter himself.

This wilderness plain is very flat, endless, completely windless, dry and cold.

After preliminary exploration, Wen Rui found that the boundary is much more vast and empty than he expected.

It is said that after passing the gate of hell, the soul of the dead can see the Yellow Spring Road and the Forgotten River, but that is only a small area near the netherworld. There is still boundless wilderness outside the Yellow Spring Road and the Forgotten River.

Once the soul does not follow the road and accidentally breaks into the wilderness, it will be like the withered human figure wandering in the wilderness, completely lost in the quiet darkness.

When enough robots are transported, Wen Rui orders Jarvis to command the robots to start exploring this area.

After the exploration, there are mixed feelings.

The good news is that the reserves of iron ore in the Earth Realm are very rich. In this way, as long as a metallurgical plant is built, a steady supply of metal raw materials for manufacturing robots can be obtained.

The worry is that the wilderness where they are located has extremely low organic matter content. The soil is like lunar soil or Martian soil, and even bacteria and viruses do not exist in it. It is a real life forbidden zone.

There are also moving "things" in the wilderness. They are withered and shriveled human figures. They seem to have no intelligence. They just move slowly and wander aimlessly.

Fortunately, these wandering things are not aggressive, and they will break at the touch, turning into a cloud of smoke and dust, but they will soon gather in the original place into human figures, get up and continue to trek.

The advantage of building a sub-base here is that the raw materials of Ultron robots and nano units are very abundant, but the disadvantage is that farms and pastures cannot be opened in the Earth Realm.

He originally planned to grow fodder and raise livestock directly in the Earth Realm, which can save a lot of trouble.

But after many attempts, even if a huge indoor ecosphere covered by glass was built, black soil rich in organic matter was transported from the mortal world, or hydroponics was adopted, crops could not be grown.

Attempts to raise livestock also failed. Even cockroaches raised in the earthly world would die inexplicably after a period of time, even if they were provided with suitable temperature, sufficient water and food.

Wen Rui also tested the radiation index and confirmed that the radiation here was not high, but it was difficult for creatures in the mortal world to survive.

Science could no longer explain it. Wen Rui could only analyze it from a metaphysical perspective, using the knowledge learned from the Jiejiao Library.

He guessed that it was because the yin energy in the earthly world was too heavy, and the plants and animals in the mortal world would be constantly depleted of yang energy here, and once the yang energy was exhausted, they would die immediately.

The earthly world is not an underground world. Wen Rui released a reconnaissance plane to explore in the air and found that there was a dark cloud above this wasteland. No matter how high the reconnaissance plane climbed, it could not fly out of the dark cloud area.

This dark cloud also has the characteristic of blocking signals. If it flies too high, the reconnaissance plane will lose contact, and the exploration of the sky can only be temporarily interrupted.

The reconnaissance plane flew in all directions, but even after flying thousands of miles, it still did not leave the wasteland.

Because he was a stowaway, Wen Rui did not expand the scope of investigation further for fear of being discovered by the ghosts of the underworld.

He only set up many hidden outposts in the area of ​​thousands of miles around the base.

In this way, once there is an abnormal situation within the range of thousands of miles, such as the ghost patrolling here, Wen Rui will be able to know it in the first time.

Wen Rui was so busy in order to open up the land base that he didn't care about looking after the Rakshasa girl. However, the Rakshasa girl seemed extremely well-behaved and followed him honestly, as if she had completely adapted to her status as a slave.

After following Wen Rui for several days, watching him busy and doing incomprehensible things, the Rakshasa girl finally couldn't bear the loneliness and asked: "Master, what are your plans? If I can't go to Jisha because of my sensitive status, Demon Realm, let’s go back to the mortal realm, why waste time in the earth realm.”

Wen Rui was looking down at the base construction drawings, without raising his head, and said: "Stop calling me master, it sounds very uncomfortable."

"What will your maid call you?"

"It's like before, just call me brother, or just call me by my name."

"This, isn't it appropriate..."

The Rakshasa girl looked cautious: "Calling you 'Master' is also a warning to myself. I always remind myself not to forget the difference in strength."

"It is precisely because I have been in the mortal world for so long that I have forgotten the rules of survival of the demon race, so I have delusional thoughts and have acted against my dignity and inferiority."

"Then you call me boss." Wen Rui said casually: "Your identity is not a slave, but my employee."

"Boss? Employee?" Rakshasa looked confused: "I have never heard of these two words. What do they mean?"

Wen Rui was stunned by the question, and after thinking for a long time, he said: "It's similar to 'master' and 'slave', but more civilized. The difference is that I will pay a symbolic salary, and you can support yourself with the salary I pay you." Own."

"It seems that the treatment of 'employees' is not as good as that of slaves." Rakshasa girl frowned and said: "After all, slaves only need to be obedient and be taken care of by their masters. They don't need to worry about how to support themselves with their salary."

"Otherwise, let me be a slave."
