My Black Tech Shelter

At eight o'clock in the morning on May 24, Lu Chen got up and added raw materials to the printer. He took out the two printed heaters and put them at the door. There were now four.

You can first contact the infrastructure maniac and ask him to come over in the morning to trade, and then contact the mechanic to come over in the afternoon. The transaction will be completed within one day, and you can save energy for a few days to expand the shelter.

Lu Chen has been eating quick-frozen food for several days in a row, and is planning to start improving the living environment after the transaction is completed and the supplies are received.

Moreover, Lu Chen discovered that the water system has not been renovated. Although there is a supply from the water plant, after the ice and snow later, even if the water plant can continue to supply water,

However, the water pipes on the road are probably unusable, so if we modify them before the temperature drops much, we can be prepared.

"And now I am planning to expand the plant cultivation room into a vegetable garden. I have enough rice reserves to use for a year.

And I also checked the information. If the temperature and humidity are suitable, rice can be harvested twice a year. In addition, I bought so many rice seeds, which can be used for a long time, so the plantation does not need to be so big. "

Lu Chen was washing and thinking about his future plans.

After washing up, Lu Chen went to the workshop after breakfast, opened the nanocore, prepared to manufacture the multi-functional processing platform, and then saw if there was any equipment that could ensure the supply of water.

Energy required for "Small Multifunctional Manufacturing Platform": 200 points

Materials required: 1000KG of metal raw materials, 20KG of rubber

Manufacturing time: 1H

Area: 2M long, 1.5M wide, 2.3M high

Description: A multi-functional manufacturing platform modified from a machining center, while retaining some of the advantages of the machining center, increases the processing capacity of complex parts and increases the manufacturing speed.

Power: 30KW

Processing size: 1000 mm

Expansion time: 1H

Lu Chen looked at the nano core. After a night of accumulation, the energy had reached 270 points. Lu Chen looked at the time and saw that it was already nine o'clock in the morning.

Then he clicked on manufacturing and looked at the working nano-core. Lu Chen left the processing room and then went to the bedroom to contact the remaining two traders to confirm the transaction time.

An hour later, following the connection with the Nano Core, Lu Chen knew that the multi-functional manufacturing platform Nano Nest had been completed.

Lu Chen came to the nano core, took out the silver-white spherical nano insect nest, came to the open space aside, activated the nano insect nest and threw it on the ground, and then the nano insect nest began to expand.

Lu Chen looked at the time. Anyway, it would take an hour to fully unfold and take shape. In addition, the infrastructure maniac would be arriving later, so he could prepare to trade items.

Half an hour later, Lu Chen watched the infrastructure construction drive away outside the shelter, thinking that when the transaction in the afternoon was completed, I would be able to own a car and travel around.

Lu Chen spent a lot of time transporting metal and building materials into the shelter. Then Lu Chen lay on the sofa in the living room and thought, if he had to carry it all by himself every time, there would be some large materials that he would not be able to transport by himself. ,

So when Lu Chen was lying on the sofa and resting, he was thinking about ways to do it.

"The best way is to use nanocore to build a robot. Because of the connection with myself, I can command it directly in my mind.

However, this would consume a lot of energy, and many facilities in the shelter now need to be renovated. Only 240 energy points can be collected in a day. The energy gap is huge, so we will not consider it for the time being and put it into the alternative;

Secondly, you can use the knowledge you have learned to process the parts yourself to make the robot. In this case, only a small amount of energy is needed to manufacture key equipment to manufacture the corresponding parts. Then it can be manufactured in batches. The advantage is that there is no shortage of manpower later.

However, there are also disadvantages. Energy consumption is expected to increase. The power generated by the small geothermal generator in the shelter is expected to be insufficient, so more power generation equipment will have to be added, and supporting programs will have to be entered. However, a micro-nano can be produced. Insect nest to assist control,

However, my current knowledge reserve is insufficient and I cannot build a robot for the time being. With my current learning progress, if I only focus on robot knowledge, I can build a simple robot to assist my work in about a month."

When Lu Chen thought about this, he suddenly remembered that he had seen in the news that there was a simple exoskeleton device in the army, which could greatly increase the strength of the human body and carry heavy materials.

At that time, I saw it said that after putting it on, one box originally required four people, but now only two people were needed. Thinking of this, Lu Chen thought it would be good to use this method first. Lu Chen sat on the sofa and opened the nano core and started designing.

"First of all, the driving method can use hydraulic pressure and motor, but I plan to put a high-energy battery on the back, so that it can be driven by motor, and the power can be stronger.

The second is the support component, which is made of high-strength alloy, and then the control program uses micro-nano nest control. "

Then Lu Chen remembered that he had heard about graphene batteries before, and then he found some information and looked at it. He found that with the ability of nanocores, graphene batteries could be made.

However, we still have to find an efficient power storage structure. In this way, by taking advantage of graphene’s fast charge and discharge characteristics and large-capacity power storage structure, we don’t have to worry about the exoskeleton’s short battery life.

Moreover, this kind of battery can be used to create vehicles with ultra-long driving range, which can also be used in other equipment.

Then Lu Chen began to search for information on large-capacity batteries on the Internet and found that most new battery technologies only contained theoretical data and no specific experimental data.

Lu Chen searched online for a while and found nothing new. He could only use the battery technology in his own distribution room. Although the battery pack in his own distribution room had high energy storage, it occupied a large area.

Finally, after Lu Chen thought about it for a while, he decided to use the structure of an ordinary battery first, and then added graphene technology to give it the ability to charge and discharge quickly.

"But we are not in a hurry to make it now. We have to wait a few days to renovate the old house before we can do this."

After Lu Chen made a memo, he checked that the time was not too early. It was almost 12 o'clock, so he walked to the processing room to take a look.

Finding that another heater had been manufactured and the remaining materials were being used to make the last one, Lu Chen took out the manufactured heater and placed it next to the two heaters he had made before, and then ran to the kitchen to cook.

After eating, it was almost one o'clock in the afternoon. After getting in touch with the machinist and confirming the arrival time, Lu Chen came to the multi-functional processing platform and prepared the materials.

He started making the parts of the crossbow. After almost two hours, Lu Chen finished making all the parts and 30 crossbow arrows, and then came to the edge of the assembly table and started assembling the crossbow.

After the crossbow was assembled, Lu Chen took a few crossbow arrows to the outside of the shelter, aimed at a tree ten meters away, and fired.

After the crossbow arrow hit the tree, it penetrated nearly five or six centimeters deep. Lu Chen nodded with satisfaction when he saw the effect. Then Lu Chen placed the crossbow in the warehouse at the shelter today. After all, he was not needed for the time being. .

Then, at about four o'clock in the afternoon, the mechanic also came, driving a trailer with the second-hand pickup truck to be traded to Lu Chen. Then the two got to know each other and completed the transaction.

Watching Wang Xingyi drive away, Lu Chen drove the pickup truck into the garage. Then Lu Chen took out a miniature nano-worm nest and placed it on the car. After starting, the nano-worm nest began to reinforce the car body, improve the strength of the car body, and check whether there was any problem with the vehicle. , after all, it is necessary to be on guard against others.

After completing the inspection, Lu Chen roughly knew the specific performance of the current car.

The load capacity has been increased from 0.5 tons to 1.5 tons, and the fuel consumption has been increased from 12 liters per 100 kilometers to 15 liters per 100 kilometers.

The tires have been transformed into run-flat tires, and the vehicle's operability, power, and comfort have been improved, which is equivalent to the entire vehicle being optimized.

However, the focus is still on the load capacity and power. After all, Lu Chen is planning to drive it to find supplies, so the comfort level is about the same. This is consistent with the optimization direction set at the beginning.

Lu Chen calculated the fuel consumption of 15 liters per 100 kilometers with a full load. The diesel he had prepared to use for the diesel generator was more than 400 liters. It could still be used for a long time to search for supplies in this city.

Lu Chen then closed the door and entered the shelter, planning to design and see how to modify the water system. After all, the government is now providing water supply, but after the cold weather, the pipes are either broken or blocked by ice. We will go there then. If you try to find a way to get water, you've already eaten it. Let's change it now so that if something happens later, we won't be passive.

Lu Chen looked at some cases of water collection systems on the Internet for a while. Based on the actual situation of the shelter, he prepared to drill a well, then prepare a 10-ton water tank, prepare a smaller water collector, and connect the pipes go outside,

When it rains, rainwater can be collected, and later the rainwater can be used to provide moisture to the plant cultivation room, which can save domestic water.

So Lu Chen planned to spend the last few days planning and renovating the shelter.

Afterwards, after dinner, Lu Chen went to the bedroom and started planning the tasks for the next few days.

"First, water resources. Because I am located in the south, there are quite a lot of underground water systems. I can dig a well. At the same time, in order to avoid unexpected situations, I need a water tank and pipes to the kitchen, bathroom and other places. Upper filter device;

Second, after the source of the water is solved, security needs to be strengthened. The main structure of the shelter itself has been reinforced. Now that there is sufficient material, the door can also be reinforced. The houses on the ground must also be reinforced to strengthen the safety of the houses on the ground and Install additional heating facilities;

The third is the plant cultivation room, which must be expanded for future survival and quality of life. Now I live alone here. The people around me have either been demolished and moved away, or have entered official shelters. I can go to the surrounding places. Expand. If other functions are needed later, you can expand further. Fruits can be exchanged for materials and Li Zhi.

So I need at least one acre of area to grow crops here, which translates into about 666 square meters. However, I have high-yielding rice seeds. The yield per mu is as high as about 1,600 kilograms. Even if the yield is reduced, I can still guarantee an output of 1,200 kilograms, so About 600 square meters is enough, divide it into half, plant rice in half, and plant vegetables in the other half.

In addition, by controlling the temperature and humidity, you don’t have to consider the season. I also checked online. If an adult consumes 500-600 kilograms of rice a year, the right amount is enough. The rest can be used to exchange for fruits, meat and other supplies. "

Lu Chen thought for a while and continued writing in his notebook:

“The fourth aspect is safety when going out. It’s not too cold outside now, but in a month the temperature outside will definitely drop below zero, so we need to consider making some cold-proof clothing.

Also, although the country has zero tolerance for illegal crimes, there are still some things that cannot be taken into account in this situation. I also have to prepare some self-defense weapons. The crossbow I made before is still a bit lacking. It can only fire one crossbow arrow at a time, and its firepower is a bit weak. It's weak. You can only find information about the repeating crossbow online, but the specific manufacturing process is still relatively difficult to find. "

Thinking of this, Lu Chen felt it was a pity. If the nano-core had been obtained earlier, then many devices would not have to be purchased. Instead, one could just find a way to copy them, master their structure, and then manufacture them directly.

If you only have drawings, the consumption will be much greater, and for many devices you cannot find drawings on the Internet. You can only deduce them based on theoretical knowledge, which will consume a lot of energy and a lot of time.

Perhaps it is because the nanocore can independently gather energy after being bound to itself. Recently, Lu Chen discovered another function in the core, that is, if there is theoretical support,

Then the core will consume different energy to create corresponding items based on the completeness of the theory. For example, the high-performance energy storage battery that Lu Chen wants most, the lithium-ion battery and sodium-ion battery that have been talked about on the Internet, if Lu Chen inputs the theory After knowledge,

According to the completeness of the theory, the nanocore consumes different energy and deduces the night theory. After it is perfected, it can consume energy to make items, or it can consume energy again to deduce the equipment to make batteries. However, if there is a complete physical object, then it can be consumed directly. It can be made with energy, so Lu Chen felt a little regretful

"Since we are going to use repeating crossbows, it is better to directly produce thermal weapons in one step. Although the most advanced firearms only know the structure and do not have detailed drawings, the drawings of bolt-action rifles and semi-automatic rifles decades ago have been declassified.

You can find blueprints by searching online, so you might as well just make a gun. But guns need bullets. Although I don’t have that much copper, our country uses steel-core bullets, which are plated with a layer of copper on the outside, so the bullet casing is Yes, but what about gunpowder?”

Lu Chen got a headache again thinking about this. After going around and around, he still returned to the starting point. If thermal weapons are used, materials and processes are lacking. Although energy can be consumed for deduction, there is also a lack of energy in other places, so in the end he can only choose to go first. Make cold weapons.

"Actually, I don't need to make gunpowder weapons."

Lu Chen suddenly had an idea. If he could make a high-energy battery, could he make an electromagnetic gun based on the electromagnetic principle?

Then Lu Chen smiled bitterly. It was all energy. It was so lacking. Think about what you should do now.

"As for self-defense weapons, let's use crossbows for the time being. I'll see if I can find the design of a repeating crossbow online later.

The fifth point is to go out and collect supplies. I already have a pickup truck, but the pickup itself has a small load capacity and limited space.

So I still have to prepare a vehicle with a large load, which I will talk about later. However, after the pickup truck was modified and its horsepower became stronger, I can make a simple hanging body to hang on the back of the pickup truck, and then install a small boom on the back of the pickup truck. It can at least drop and move items weighing a ton.

In this way, heavy items can be transferred directly to the truck body hanging at the back, and light items can be carried by myself, especially those building materials, which can save a lot of effort and time."

After writing this, Lu Chen could only consider these aspects for the time being. We would talk about it later if there were special circumstances. Then Lu Chen looked at the time, studied for a while and then went to rest.
