My Black Tech Shelter

On May 22, the second day after the meteorite fell, Lu Chen got up in the morning and started preparing materials to make a heater. However, it would be a bit of a loss to use the nano core directly, so Lu Chen planned to upgrade the 3D printer in the workshop first. Lu Chen looked at the upgrade interface

"Industrial 3D metal printer

Printing range: metal

Power: 10 kilowatts

Transformation direction: Industrial 3D printer-composite 3D printer

Attributes after transformation:

Printing range, metal, polymer

Power: 15 kilowatts

Transformation consumption: 100 energy points"

After Lu Chen selected it, he confirmed the manufacturing, and soon, a nano insect nest was manufactured.

Then Lu Chen came to the workshop and put the nano insect nest on the printer. The silvery-white nano insect nest suddenly turned into flowing water and began to merge into the printer.

When it was fully covered, the nano insect nest began to extend, and soon it occupied half of the size of the workshop. After a while, the shape stabilized, and then the silvery-white liquid began to gradually turn into a solid. Lu Chen looked at it and estimated that there was still half an hour left, so he went out to wash up and come back to see.

After half an hour, Lu Chen came to the workshop and found that the printer had been transformed. What appeared in front of him was a closed processing equipment with a sense of science fiction, just like a small processing center, but there were not as many equipment in the processing center.

Lu Chen looked at the processing equipment in front of him, thinking that it was worthy of being the creation of an advanced civilization, it was awesome.

Then he opened the manufacturing interface and prepared to see what he could make, but found that the manufacturing interface was blank. Lu Chen saw this and thought about it and found that he had to import the drawings.

Lu Chen then took out the USB drive to import the blueprint and checked the manufacturing interface. He found that it would take about 50 kg of metal materials to make a small heater. As long as the metal materials were put into the raw material inlet, the printer could dissolve them into metal powder by itself, and then read the blueprint for manufacturing.

Then Lu Chen did some research and found that the printer could only hold 100 kg of raw materials at most, so items over 100 kg could not be manufactured for the time being. However, the shelter was not large at the moment, so small equipment was enough and could be upgraded later.

Then Lu Chen brought 100 kg of metal raw materials from the warehouse, put them into the printer, and then chose to make a small heater. The printer showed that it would take 4 hours to make it. After Lu Chen set it to make two pieces, he began to check how to reinforce the shelter.

There are many manufacturing blueprints in the nano core, but these blueprints were optimized after Lu Chen got the nano core and used the nano core to download the scientific and technological information on the Internet. They still belong to the technology on the planet.

Most of the blueprints can be manufactured by the technology on Earth, but they are not as good as those made directly by the nano core. After all, it is nano-level processing, and the processing accuracy is different. For example, the processing accuracy of gears is different, and the service life and usage accuracy will also be different.

Now Lu Chen wants to reinforce the shelter. After all, the volcano has been erupting frequently due to meteorites recently, and there will be aftershocks from time to time, so it is imperative to improve the earthquake resistance of the shelter. After all, if even the shelter is destroyed by the earthquake, then it is useless to say anything else.

"Special nano insect nest manufacturing consumption: 100 energy points, metal 1000KG

Description: Specially manufactured nano insect nests, after setting the range, can enter the wall and foundation, transform the steel bars in the wall and foundation from the nano level, strengthen the steel density, strength and toughness, and at the same time strengthen the wall solidity and increase the wall hardness."

Seeing that there is enough energy, Lu Chen chose to manufacture, and then after the manufacturing is completed, put the nano insect nest on the ground. After starting, only silver water flows continuously in the shelter. When it covers all the walls, ceilings and floors, it gradually sinks into the interior until it disappears. Then Lu Chen takes the nano core to scan the entire shelter, showing that it is being reinforced, and the estimated completion time is 1 hour.

After finishing all these, it was almost noon. Then Lu Chen thought about it and found that there were many things he couldn't do for the time being, so he went to study first.

. . . . . . . .

At the same time, the netizens on the forum who were ready to trade with Lu Chen began to prepare to trade materials.

In a group of mountains, there is a hidden shelter at the foot of the mountain. The internal space is much larger than Lu Chen's shelter. There is also a small plantation inside. At the same time, there is an orchard in a small valley on the mountain. This is the original home of the fruit farmer.

Originally, the fruit farmer had an orchard at home. When the disaster came, he opened a shelter at the foot of the mountain. Because he was a grower, he still had some assets, so he built a bigger one. And considering that the orchard was outside, for safety, he also opened a small plantation inside, just in case.

At this time, fruit farmer Li Zhi left the shelter and began to collect fruits in the orchard. After filling three sacks, he loaded them into a Wuling car and prepared to trade them in the afternoon. However, Lu Chen had not given him the address yet, so he could not go for the time being. However, Li Zhi also sent a private message to Lu Chen on the forum and waited for Lu Chen's reply.

…

In a large courtyard, there were building materials everywhere, and there were cameras all around the courtyard wall. There was also a large warehouse in the courtyard. This was the home of the infrastructure maniac.

Infrastructure maniac Xu Jian's family was in the building materials business. They had a rich family background and did not want to suffer in the official shelter, so they also spent most of their property to build a shelter, located below the warehouse.

At the same time, adequate safety facilities were installed, including a large number of surveillance cameras and infrared alarm devices in the courtyard. A half-meter-high high-voltage power grid was set up on the courtyard wall. And because we had money, we built solar panels on the top of the warehouse and in empty spaces in the courtyard to generate electricity. , and two wind turbines have also been set up, so there is no need to worry about electricity and a high-voltage power grid can be established.

At this time, Xu Jian and his father were loading some building materials and metal ingots into a small truck, which were also used for trading with Lu Chen.

After Xu Jian loaded all the things into the car, he said to his father:

"Dad, you can go and have a rest after putting this batch of supplies in the car. I will go down and contact Mi Chong later to see when the transaction can be made tomorrow. I will drive there by then. You are at home. Anyone can Don’t open the door when you come, even if you are an acquaintance.”

Xu Guoli replied: "I understand, I'll go down first. Your mother's food is probably ready soon. You can come down to eat when you are done with your work later. You can also confirm the trading location with your friend in the evening. Don't worry if you trade early."

"I got it, Dad! Get down quickly."

Xu Jian replied, and then watched his father walk into the shelter and began to check the vehicle to ensure that it could be used normally tomorrow.

…

There is a two-story house next to the highway, with a signboard "Wang Xinyi Vehicle Repair Center" hanging on it.

This is the home of mechanic Wang Xinyi. The upstairs is a residential home, and the lower floor is for repairing vehicles. There is a small yard at the back with a small parking lot. There are several cars, including an SUV and a small parking lot. An off-road vehicle, a pickup truck, and an accident tow truck.

Wang Xinyi is a car mechanic and a master of modification. Many rich second-generation car owners like to come to him to modify their cars, so he also has a lot of wealth (as expected, private shelters are not affordable for ordinary people).

Therefore, he spent a lot of money to build a shelter under his home. The interior extends to the yard, so the space is still very large (at least these three netizens are richer than Lu Chen). When disaster strikes, Wang Xinyi chose to be with his wife and children, and since he was far away from the city, he had nothing to lose.

Now Wang Xinyi is repairing a pickup truck in the yard. This pickup truck was used to pull goods. It was bought not long ago and cost only tens of thousands of yuan. Unexpectedly, disaster struck after a few uses, and it was left idle. Now that I'm at home, I think it's worth it to exchange this little-used car for three heaters.

After all, after a disaster strikes, many cars will be abandoned on the road. You can just pull a few cars back and assemble them to make a car. But you don’t know how to make the heater yourself. It’s okay to repair it. If you make it yourself, there are no drawings and no processing. Equipment, so I would like to exchange it with something I have at my fingertips. After all, heaters will be a hot commodity in another month.

"After the heater is replaced, we will put one on the first floor of the second floor and in the underground shelter to ensure that it does not get cold. Moreover, we can also exchange other equipment with Mi Chong later. He can manufacture these sophisticated things. It shows that he is engaged in the manufacturing industry and is probably a leader in the industry.”

After Wang Xinyi inspected the car, he got up and sat next to him to rest. He thought that Lu Chen probably had a lot of manufacturing capabilities. Now he had established a good relationship with Lu Chen. If he needed any equipment later, he could exchange it with Lu Chen.

"It's impossible to say that Mi Chong can even make guns!" Thinking of Lu Chen's manufacturing ability, Wang Xinyi couldn't help but think about this.

I stood by the car and thought for a while, then put four brand new tires, an automatic air pump, and some fuel into the car body. When I was preparing to trade the day after tomorrow, I asked if I could trade another heater. After all, I had an extra spare. is also good.

…

After waiting for the alarm clock set by Lu Chen to ring, Lu Chen got up from the computer and went to the workroom to take a look. Two heaters had been processed. After taking off the two heaters, Lu Chen took out 100KG of metal from the warehouse. Put the raw materials into the printer and let it continue to work. Then contact the fruit farmer on the forum and send the address privately to the fruit farmer so that he can come and trade.

…

After receiving the message, the fruit farmer here looked at the time. It was already around four o'clock in the afternoon. He looked at the address and found that it would take half an hour to drive to Lu Chen's place, and an hour to go back and forth, plus the half hour required for the transaction. I arrived home when it was almost dark. After saying hello to my family and asking my family to take care of the house, I drove off.
