After eating, Zhang Tao came to the warehouse to take away the things blocked above the hole, and remotely controlled the drone to send the purchased things to the underground space, and the corners of the underground passage were installed with reflective signals, and the drone was also modified to fly automatically, and multiple drones could be remotely controlled to fly to the underground space at a time.

At 10 o'clock in the evening, I sent the purchased things into the underground space halfway, and the next day I got up early and had dinner and continued to transport things to the underground space, and transported all the materials to the underground space before the sun shone.

Next, the decoration of the underground passage began, the cement was paved in the longitudinal passage, and now only the transverse passage was left, and the remote control robot pulled the pump pipe for pumping water to the place where the cement was needed, and then loaded the cement and sand with a shovel and brought it over.

Open the cement and sand and pour them on the ground, put the bags in a nearby room with garbage, and wait until the passage is finished with cement before taking them to the ground.

Let the robot use a shovel to stir the cement and sand back and forth several times, and after mixing the sand and cement evenly, the middle part is loaded with a shovel and placed around to form a pool.

The remote control drone turned on the pump with a mechanical arm, and after more than ten seconds, the water pipe came out, and then the pump was turned off after the pool was filled with water, and the water in the pool slowly invaded into the cement and sand around when it flowed out of the water pipe.

Then remotely control the robot to shovel some cement and sand in the thin part of the pool to prevent the water from flowing out, and push the mixture of sand and cement into the water from the middle of the pool, so that the water and the mixture are fully mixed, and when the water is not enough, start the pump and then receive some water.

After the reconciliation, the cement and sand are remotely controlled by the robot and shoveled up and thrown to the wall, using the acceleration and the stickiness of the cement itself to stick to the wall, just like throwing mud on the wall.

After throwing the cement on the three walls of the 100-meter passage, the remote control robot uses a shovel to carry the pangolin-type drill, so that the driller emits a shock wave against the wall to shake the wall flat, and some excess sand and cement fall to the ground.

After the walls are leveled, turn on the spring coil of the drill and send out several supermarket ultrasonic waves against the wall, evaporating most of the water in the cement wall, so that the wall dries out quickly.

Then spread the remaining cement and sand on the ground, while paving, the pangolin-type drill was remotely controlled to pop out the spring coil to evaporate some of the water in the ground, and after the ground was paved with cement, wait for a while, and then remotely control the drill to the ground to send out a shock wave of stones and soil to shake the ground flat.

The remaining 1,000 meters were also laid at 6 o'clock in the evening, and the next step was to lay the cables, ventilation ducts and water pipes.

Zhang Tao walked in the yard for a while after dinner, and returned to the bedroom at seven o'clock, sat in front of the computer and remotely controlled the drone, grabbing the cable from the place where the oil is refined to the hole at the corner of the first slope below the warehouse, the lights of the warehouse can illuminate the first slope, so that others will not find anything if they find the hole immediately, although this possibility is very small, but be careful to make the ship of ten thousand years.

If there is a thief who is poor and crazy to find something to sell in the warehouse, and then continues to commit the crime and is caught by the police and says that it is not safe, I have read the newspaper report before that many secret things are known in this way, and the thief is a good helper for the police to solve the case.

The cables in the channel are hooked on the wall with hooks that stick to the wall, the walls are very smooth, the sticky hooks can bear four or five pounds of things, just put a few more sticky hooks, if you nail the wall will destroy the cement, and the waterproof layer will be made in vain.

The hair dryer cloth is also used to bear the weight with a hook, but the diameter of the hair dryer cloth is somewhat large and tied to the iron hook with a thin wire, the hair dryer cloth is used to pump the wind on the ground to the ground, and the hook is not very heavy, and the hair dryer cloth is also spread into the first corner hole at the entrance of the warehouse.

The oil and water pipes were laid from the place where the oil was refined to the newly opened rooms in the passage, and they were not very long and were placed against the wall.

After a day, the pools in all five rooms were built and the asphalt could be refined. Three of the four pools in the room are used for refining petroleum and the other for distilled petroleum products.

In addition, there were a total of 24 pools in the original room to refine asphalt, so Zhang Tao went to the steel factory in the city to buy some steel and other materials, and asked the steel factory to deliver the goods to the house down the mountain.

Zhang Tao processed the steel sent by the steel factory with a machine tool to make it smaller in weight and volume, packed small pieces of iron and iron filings in bags, pulled them back to the forest farm villa in a truck, and then took them to the underground space by drone.

Using iron blocks and iron filings to plate several pools into iron walls, Zhang Tao removed everything in the warehouse that blocked the holes, then opened the windows and locked the door and returned to the bedroom, using a computer to remotely control the robot to start a diesel generator and wind pump to deliver air to several rooms where oil is refined.

Then turn on the pump to pump oil from the oil field to fill the twenty-four pools, this time Zhang Tao put a few pools on top of the aluminum alloy plate that can be folded, the evaporated oil will fall into the empty pool faster, the original use of hair dryer cloth will be used for a few days will be burned by oil vapor, but also have to change to a new one.

A robot was placed in each room, Zhang Tao made the remote control device of several robots on a remote control, numbered the robot, and the digital buttons on the remote control corresponded to the switches of several robots, which was very convenient.

The gasoline is first refined, and when the pool is full, it is pumped back into the oil field with oil pipes and pumps, then diesel is refined, and finally the remaining heavy oil is refined into asphalt. Both gasoline and diesel are much more expensive than asphalt, and Zhang Tao has done this to buy some more money, but it is also worth it for the benefit of his hometown.

There are many more profitable trades than oil, and when the time comes, you just need to make the money back. The asphalt refining robot can do it automatically, Zhang Tao just checked the situation every once in a while, and used a small water tank to make bread in his spare time, and gave the bread to his relatives.

After the asphalt is refined, a pool is used to fill it with water, and then a drilling pipe and a water pump are used to pump the asphalt into the pool, the asphalt is insoluble in water, and after it is in the water, it floats in the water to cool off the asphalt solids.

The remote control robot uses a screen to fish out the asphalt blocks from the pool, and then lets the drone grab the asphalt blocks into bags and transport them to the warehouse. When the asphalt can fill the truck compartment, the asphalt is pulled to the house at the bottom of the mountain for storage, and the more than 20 houses that Zhang Tao bought have not been rented out, and there is still a lot of space left after storing the asphalt.

When pulling asphalt, it is pulled at night, and the asphalt bags are not visible to others in the truck. Zhang Tao became more and more proficient in making bread, and everyone liked to eat the bread he made, so Zhang Tao made more to give to his relatives, and if he couldn't eat it, he could also give it as a gift to their relatives and friends.
