When the robot as4 saw that the owner was back, he was very happy. It turned on the searchlight on its head and led the way in front of it as a lighting, and opened another house. This was the original owner's room. With the help of the light, Wei Zhen and Jing Zhonghua saw that the entire house was so dust that it could not be cleaned. The furniture and supplies in the room had long decayed and fell down as soon as they touched it. The bed had completely collapsed. The robot as4 kept complaining about itself:

"I'm sorry, the master, this room cannot be accommodated, I didn't care..."

Wei Zhen patted the head of the As4 robot and said, "Okay, we'll live here, you go back."

After the As4 robot left, Jing Zhonghua asked:

"How can people live in this room? It's dust everywhere. It's better to stay in the wilderness of the immortal cave for one night."

Wei Zhen pointed to a large metal box and said:

"I saw that there was a metal box there. We used the box as a stool and sat all night."

Jing Zhonghua stepped forward and swept the dust on the metal box with her hand. The metal that removed the dust was exposed and shone brightly. It should be made of special metal. After carefully watching the lock on the box, the lock was rusted. She pointed with her finger and a beam of laser knocked off the iron lock. She opened the box and saw that it was a gun that looked like an automatic laser rifle but had a strange shape. She picked it up and looked at it for a long time and found the gun lock switch. The data showed that the gun still had a lot of energy and could be used. Jing Zhonghua pressed the gun against the wall, and a beam of blue light shot out, hitting the wall of the room, and suddenly punched a deep hole in the wall.

Jing Zhonghua wanted to try again, but was stopped by Wei Zhen and said, "This gun should be a special gun. It is best not to touch it before you understand its purpose."

She turned off the switch of the gun, put it aside, and continued to search in the box, which were filled with tools for repairing machines, as well as tools such as axes, chisels, chainsaws, electric planes and small welding machines.

Jing Zhonghua complained, "What kind of box is this? There is no treasure inside and it is locked. How can these things be used without electricity?"

Wei Zhen guessed, saying: "This may be because the people from Heaven gathered all the tools together and locked them when they evacuated."

Jing Zhonghua shook the gun in her hand and asked, "What's wrong with this gun staying here?"

Wei Zhen shook his head and said, "I can't guess... This gun must be their treasure locked in the box... It is possible that this person has forgotten it in this box in a hurry and wants to wait for him to come back to pick it up in the future."

Wei Zhen took out an axe from the box and said, "This axe is quite sharp and can be used as a weapon."

Jing Zhonghua leaned over and flipped the box through, and she stood up and said:

"These tools are just right for helping with micro man-made houses. Their houses are bungalows, and we use these tools to build them a tall building."

Wei Zhen nodded and said, "Well, what you said makes sense, but... we lack the drawings, construction materials and construction experience for building buildings, so it may be difficult."

"It's not difficult." Jing Zhonghua told him, "I have built thirty-story buildings for them. I have experience in design and construction. I just have problems with the building materials. I don't know if I can find the materials we need here."

Early the next morning, Jing Zhonghua and Wei Zhen found the As4 robot together, Wei Zhen asked:

"Do you have any materials for building a house here?"

The as4 robot did not know what materials Jing Zhonghua needed, so he took her out of the hall and arrived at the abandoned castle. He walked several streets on the street buried by wind and sand. Finally, he came to a large pile of sand. The as4 robot pointed at the pile and said:

"This is a building materials warehouse, and I don't know if the materials inside are what you need."

Jing Zhonghua was anxious to find the building materials she needed, so she began to dig up the sand pile in front of her with her hands. Unfortunately, the sand pile in front of her was too big and the speed of digging with her hands was too slow. Wei Zhen found three shovels, and three shovels kept digging, and finally dug out the door.

The door was still locked, and the shovel smashed the lock open. After the door was opened, it was indeed a large building materials warehouse. Various steel, aluminum and other metal building materials were neatly stacked inside. At the same time, a large amount of cement stacked may still be used due to the dryness and airtightness of the warehouse.

With so many building materials and cement, it is no problem to transform the entire Shenxian Cave. Jing Zhonghua said in surprise:

"Our building materials have been solved, but there are no processing tools."

Wei Zhen asked the as4 robot: "Can you find processing tools?"

The as4 robot thought about it and took them to a house not far from the warehouse. The house had collapsed. They drilled into a hole that collapsed and saw that there was a factory with machine tools and mechanical processing equipment, but it had been weathered and rusted and could not be used. However, they found a sealed box in a room in the factory, which contained a brand new hand-crank generator. After Wei Zhen installed the engine, he tried it with his hands and found that the generator was not damaged. He called the as4 robot hand-cranked generator. He tried many electric tools, and they could all be used. It really made Wei Zhen realize that these equipment could still be used after being idle for so many years.

Now the hall of the abandoned castle became a processing plant for building miniature houses. Jing Zhonghua designed a 40-story building for Shenxian Cave castle. Wei Zhen felt that the design of Jing Zhonghua was too high, which affected the beauty of the entire Shenxian Cave. Jing Zhonghua told Wei Zhen:

"The 40-story building is not high, the micro-person is 4 cm high, and the floor height of each floor is 7 cm, and the entire building is 3 meters high. The building materials we use are completely free of problems. The height of 3 meters is 3 meters. Compared with the highest mountain in the cave, I estimated that it is about 40 meters high, and the average mountain is 10 meters, so there should not be any problems."

Wei Zhen asked: "How do you solve the elevator in the building?"

Jing Zhonghua answered confidently: "I have long thought of this question. I secretly placed 30 micro elevators in each of their detectors, and there are a total of 120 elevators to be spared, which should be enough for them."

Wei Zhen praised Jing Zhonghua and said, "You think about them well enough."

Jing Zhonghua shook her head and said, "It's not that I'm considerate, but that the manufacturer has less than 140 units and they don't produce them. I still have more than a dozen units in my house."

Wei Zhen is a skillful person. He completed a 40-story building in less than a week. At the same time, Wei Zhen also used the spare materials to build three exquisite courtyard houses, and the task was completed.

Jing Zhonghua looked at the exquisite building and said:

"Your building is better than what I have in the General's Mansion. I thank you on behalf of the miniature."

Wei Zhen said proudly: "I just built a building toy, not a high-end technology, what's there to praise? If I had planned and built the castles of Shenxian Cave, I would have built them into a fairy-like residence."

Jing Zhonghua curled her mouth and said, "You are fat, you are really accustomed to it."

Although the house was built, the spare dry food on the two of them was finally eaten. If they didn't find a way, they would go hungry. Wei Zhen thought that moving all the prepared houses to the magic cave tomorrow would take care of them. He could use the energy in his body to persist, so that Jing Zhonghua could not eat or drink and support her body's energy. It is not possible for them to eat miniature human food, so Wei Zhen asked the robot as 4:

"You said that a strong frog lives by eating fish in the water and shrimps. Which cave has water, fish, and shrimps?"

The as4 robot immediately nodded and agreed to take them to find the cave. Under the leadership of the as4 robot, they quickly found the cave with their fishing tools.

Because the sun shines into the cave on the top of the cave, the light in the cave is very good. There is a large deep pool, and many plants have grown by the pond. When the flowers in the scenery look, they jump up happily and said:

"There are apple trees here...there are vegetables under the trees. Oh, it seems that someone is planting them here before."

The as4 robot nodded and said, "You are right. This used to be a supplement to the owner's food."

"Oh." Wei Zhen understood.

Jing Zhonghua couldn't wait to pick an apple from the tree and eat it. However, Wei Zhen discovered the kiwi fruits that were rarely seen on Earth. He stepped forward to pick a few, took them in his hand, looked at them, and said:

“The kiwi fruits here are good.”

Jing Zhonghua snatched one from Wei Zhen and said, "I have never eaten kiwi fruit before. Is it delicious?" She took a bite of the kiwi fruit and screamed: "It's delicious!" She immediately squatted down and picked a lot and put it in her pocket.

Wei Zhen was mainly here to catch fish. He and the As4 robot came to the edge of the pond and saw a lot of fish in the pond. Wei Zhen used a fish net bag to scoop into the water. A 5-pound fish was scooped into the fish net bag. He said happily:

"Enough, this fish is enough for us."

The as4 robot told Wei Zhen: "Your fish is too small, this is a small fish."

The as4 robot aimed the harpoon in his hand at a big fish in the pond. A big fish worth about ten kilograms was stabbed by it and caught it. Then it caught three consecutively. If Wei Zhen had not stopped it, it would have continued to catch it. There were four big fish and picked a lot of fruits and wild vegetables. The flowers and Wei Zhen felt that they were enough to eat, so they returned with a full load.

In the hall, they ate a meal of fresh fish and vegetables that they hadn't eaten for a long time. Then they slaughtered the four fish into small pieces, cooked them and put them in a bag, preparing to get the magic hole for the miniature people tomorrow.

With the help of Wei Zhen and Jing Zhonghua, the miniature people in the magic cave have now added an iconic modern 40-storey building to their castle. Regardless of whether the miniature people accept it or not, they designed shopping malls, restaurants, theaters, etc. in the building. At the same time, three very unique courtyards were built in a beautiful place. In order to facilitate travel, the two built a cement road running through the north and south in the castle.

Although Wei Zhen has returned to secular life, he still cannot forget to preach to the miniature people and promote Buddhism. He built a pagoda on a mountain more than 2 meters high near the castle, and built a new temple next to the pagoda, which specially opened a road to the mountain, named Yanggong Temple. He inlaid the Buddha statues he had been wearing in the temple hall for the miniature people to go up the mountain to worship. He believed that the souls of the people in the Heavenly Soul Hall were injected into the bodies of the miniature people. They were reincarnated, and some of them would definitely understand Buddhism.

Jing Zhonghua looked at the temple repaired by Wei Zhen and said:

"You will never forget your Yanggong Temple wherever you go. The miniature people do not believe in Buddhism. It will be useless for you to do this."
