My Black Tech Shelter

July is usually a pleasant time, but this year’s July was so cold that even the bare-legged magic weapon was useless.

After getting up on the morning of the 1st, he saw that the energy had reached 120 points, but it was not enough for the time being. Lu Chen planned to use a 3D printer as the basis for the processing room to form a small automated assembly production line, so that the printer could be used to print parts and then use the products. The lines are assembled,

However, this Lu Chen needs 1,500 energy points after the nano-core deduction. Judging from 240 energy points a day, he will have to wait a few more days.

Afterwards, after Lu Chen washed up, he went to the garage to check the condition of the vegetables in the carriage and found that they were well preserved. Lu Chen nodded, then took out the trolley from the warehouse and put it in the car, and drove to the official transaction district.

An hour later, Lu Chen arrived near the official shelter. As he approached the official trading area, more vehicles began to appear, but many of them were electric tricycles, as well as some SUVs, pickup trucks, etc., and there were more than a dozen vehicles in the distance. There are people sitting in the big truck,

Moreover, Lu Chen observed that in addition to those electric tricycles, there were people staying in other SUVs, pickup trucks, and container trucks. Lu Chen felt a little envious when he saw this. After all, he had been living underground alone for a month. If he hadn't been Being busy, I probably feel uncomfortable too.

However, before Lu Chen saw that there were only a few people in the forum he was in, he thought that there were not many private shelters. But today he found out that it was not that there were not many, but that he was too homely to look for these shelters. But today he came to the transaction It's not too late to get there. Then you can see if there are any items or specialties you need, and you can trade them privately later.

Then Lu Chen parked the car on the roadside near the trading area, put on his helmet and got out of the car, took out the trolley from the car and placed it on the ground, then unloaded the vegetables on the trolley, locked the door, and pushed it The car entered the trading area.

As soon as you enter the trading area, you will see a vast room in front of you. The space inside is very large, just like a vegetable market. There are stalls one by one, but the intervals between stalls are still relatively large. There is an announcement next to the door. The sign says

——

1. This trading area is a trading place opened by the government. There are two trading methods. One is to rent a stall and set up a stall by yourself and barter. The other is to exchange the materials you own into the official shelter. Credit points, use the credit points to exchange for the supplies you need,

2. Fighting and other criminal activities are prohibited in this trading area. Please abide by the relevant laws and regulations of Dragon Kingdom.

3. Stall rental requires credit points, and materials can be used to exchange for credit points.

——

Afterwards, Lu Chen saw the materials that could be exchanged and the exchange locations written at the bottom of the bulletin board, and pulled the trolley to the material exchange office. There was also a sign next to the exchange office, which stated the exchange prices of some regular materials.

1kg of rice = 1 credit point

1kg of ordinary metal = 1 credit point,

1kg of fruits and vegetables = 10 credits

10kg of plastic = 1 credit point

There were some supplies below, but Lu Chen couldn't use them for the time being. Later, Lu Chen exchanged 50kg of cabbage, applied for a card, and had 500 credit points credited into it, and then spent 10 more credit points to rent one. Stall, put your own vegetables on the stall.

What Lu Chen didn't expect was that when the people around him saw that the supplies Lu Chen set up a stall were vegetables, they immediately took a breath of cold air. It was not that no one had set up a stall to sell fruits and vegetables, but they had never sold so many fruits and vegetables to Lu Chen, 300kg of cabbage. And 90kg of lettuce, maybe it was nothing before the apocalypse, but what is the situation now? Every inch of land in the underground shelter is extremely precious. Who would spend a lot of space to grow vegetables? Those who have such a large space usually have strength. Relatively strong corporate shelters, and corporate shelters are not just for one person, but for many people, so they generally grow staple foods. Only senior executives and technical personnel can eat vegetables and fruits. They are not available for every meal, and vegetables are not available for every meal. Fruits consume a lot of water resources. Although staple foods also consume water, they also consume water resources, so it is not as good as growing staple foods.

A lot of people immediately gathered in front of Lu Chen's stall. Everyone was asking Lu Chen how to trade. When Lu Chen saw that there were so many people, he took out the small sign that he had prepared. It read

10 kilograms of ordinary metal = 1 kilogram of vegetables

1kg of fruit = 1kg of vegetables

10 kg of rice/wheat = 1 kg of vegetables

10 ordinary electric car batteries = 5 kilograms of vegetables

1 liter of fuel = 10 kilograms of vegetables

Everyone fell silent looking at the price tag above, and then everyone returned to their stalls to discuss with their own people. Lu Chen was not worried when he saw people leaving. After all, there were so many vegetables here, so no one wanted them. Moreover, Lu Chen’s goal is not these individual people. The main target is the official shelter. I believe that even if it is as powerful as the government, it is impossible for everyone to have vegetables for every meal. The police and some officials may only eat vegetables every few days. Once a vegetable, the next target is those corporate shelters. Although the official shelters have recruited a lot of talents, the background of some large groups cannot be underestimated, such as those Internet giants and some industrial giants. They need technology and technology. , resources are needed, and now the government has lifted military control of those mines and returned them to their previous owners.

After Lu Chen waited for a while, people came to exchange vegetables one after another, but they were all small orders. After a while, a group of people came from a distance and came to Lu Chen's stall. The leader smiled. Said to Lu Chen:

"Hello boss, I am the person in charge of the administrative division of Ali Company. My name is Wang Dong."

"Hello, I'm Lu Chen"

Lu Chen looked at the person in front of him and introduced himself.

"Boss, we, Ahri, have collected all of your vegetables, and we are using ordinary metal in exchange."

"Okay, I have 200 kilograms of vegetables left here."

"Then we will give you 2 tons of ordinary metal ingots, boss. Please wait for an hour and I will notify the company to send someone to deliver them."

Lu Chen spent 10 credit points to rent a warehouse and put the exchanged materials into the warehouse. Among them, he replaced a lot of electric vehicle batteries. After all, these things are relatively easy to get, but metals, food and fuel are basically unavailable. It was exchanged, so Wang Dong's batch of metals came in time, allowing him to save a lot of energy.

Then, while Lu Chen was waiting for the supplies from Wang Dong, he walked around the exchange to see if there was anything he could use. After walking around, Lu Chen found that most of the people at the stalls were The items on display were common materials found in the city, such as scrap iron, plastic, etc. In the end, Lu Chen felt that these individuals probably had all the good stuff hidden, and they had to make deals with large companies or officials.

An hour later, Wang Dong's truck transporting supplies arrived. After Lu Chen loaded the items from his warehouse onto the trolley, he led Wang Dong and his group to where he parked his car.

Then Wang Dong's employees began to unload the metal ingots on the ground. Each bundle of these metal ingots weighed 100 kilograms, a total of 20 bundles. Lu Chen also handed the vegetables to Wang Dong, and then carried a bundle of metal ingots to his car in one hand. Put it up,

Wang Dong looked at Lu Chen who was wearing protective clothing thoughtfully. Wang Dong still knew about the hydraulic power-assist device, but there was no power-assisted device like Lu Chen that could easily lift 400 kilograms.

And in order to drive such a huge power, and the style of the protective suit looks a bit like the power armor in science fiction movies, I guess the energy system should be very good.

Afterwards, Wang Dong saw that after the transaction was completed, he walked to Lu Chen and started chatting with Lu Chen.

"Boss Lu, look at your outfit, it's not that simple,"

Lu Chen looked at Wang Dong and said casually: "Where it is, it's just something I did casually, it's not worth mentioning."

Wang Dongyou said casually: "Boss Lu, you are being humble. If you want to move normally, your energy system is unusual. The protective clothing we are wearing now has a limited activity time and can only last for four or five hours. It is not as good as going to the mainland." The boss is so persistent.”

"Oh? This means that your battery is not good and cannot store enough power."

"Yes, yes, it seems that Boss Lu can get high-capacity batteries. If I want to replace some batteries from Boss Lu, I wonder what Boss Lu thinks?"

Lu Chen looked at Wang Dong and was silent for a while. In fact, he was very happy. He was really dozing off and gave him a pillow. After upgrading his battery, the original graphene battery was no longer used. He was about to find someone to take advantage of. Can you use this backward product to exchange for some supplies? I didn't expect this Wang Dong to be so smart.

After thinking for a while, Lu Chen said to Wang Dong: "It is difficult to manufacture this kind of battery here. The technology is very difficult and the output is very low."

"Boss Lu, we won't let you suffer. If you have any needs, you can ask us."

"I am currently studying the technical difficulties here, but I really have no good solution due to the lack of raw materials. So if you want this kind of battery, you must provide raw materials. According to the quantity of materials you provide, the battery you produce will be You can take away 70%.”

After hearing this, Wang Dong thought for a while and said:

"In that case, Boss Lu, what is the specific performance of the battery you are studying? With the specific parameters, I can report to the company to confirm whether it is a transaction."

"Yes, this battery uses graphene technology, which can charge and discharge 10 times faster than ordinary batteries, and the energy density is also good, reaching 1000WH/kg, which is twice as high as the density of batteries on the market. How about it, Manager Wang, this data is okay."

Wang Dong took a breath when he heard this. What did Lu Chen do before? Is it so scary to get a battery? The best battery density for ordinary electric cars is only 300WH/kg, and the charging speed is average. Lu Chen's battery parameters would definitely have caused a sensation in the past, but now I am the only one who knows about it, so I must have a good relationship with it.

Wang Dong knew that Lu Chen was not a simple person. He not only had achievements in batteries. Just looking at this armor, he knew that Lu Chen could definitely make weapons if he wanted to. Moreover, the authorities were also eyeing these companies now, so If you want to do something secretly, you must set up a lantern in the toilet to look for shit.

Then Wang Dong asked Lu Chen to wait for a moment, and then immediately reported the situation to the company, and then watched what Wang Dong kept saying on the side.

On this side, Lu Chen watched Wang Dong contact the company and wondered whether their communicator was made by their company or where he exchanged it. Due to the disorder of the magnetic field in the Blue Star, ordinary mobile phones were basically unable to communicate, and only wired ones were left. The network was still working, so Lu Chen found it incredible that Wang Dong could contact the company remotely.

After a while, Wang Dong came back and told Lu Chen that the company agreed to Lu Chen's plan. Then he exchanged the addresses of their respective shelters with Lu Chen and agreed to send the materials and contracts to Lu Chen's shelter in a few days. After signing the contract on the spot, he handed the raw materials to Lu Chen.

Lu Chen also asked Wang Dong about the communicator, and then he knew that it was exchanged from the official, but it was not on the public exchange list. If you know this news, you can also buy it if you ask it personally, but the price is very expensive, worth 10,000 credit points, and ordinary people can't afford it. In addition, the production is limited, so the exchange is not opened.

After listening to it, Lu Chen couldn't help but sigh at the strength of the country's scientific and technological power. It's not long since the doomsday, and these black technologies have come one after another. Before the doomsday, 5G was not laid out, and after the doomsday, quantum communication was directly developed. A group of awesome.

Afterwards, Lu Chen and Wang Dong and his party said goodbye to each other and began to return to the shelter.
