At eight o'clock in the morning on May 24th, after Lu Chen got up and added raw materials to the printer again, he took out the two heaters that had been printed and put them at the door, there are already four of them, you can contact the infrastructure maniac first, let him come over to trade in the morning, and then contact the mechanic to come over in the afternoon, end the transaction within a day, and then save a few days of energy to expand the shelter.

Lu Chen has been eating quick-frozen food for several days in a row, and is ready to start improving the living environment after the end of the transaction, and Lu Chen found that the water system has not been transformed, although there is a supply of waterworks, but after the ice and snow in the back, even if the waterworks can continue to supply water, the water pipes on the road are estimated to be unusable, so if the temperature has not dropped much now, you can be prepared.

"And now I am going to expand the plant cultivation room into a vegetable field, the rice reserve is enough for a year, and I also checked the information, if the temperature and humidity are suitable, the rice can be harvested twice a year, plus I bought so many rice seeds, it can be used for a long time, so the plantation can not be so big."

While Lu Chen was washing, he was thinking about his future plans,

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

......

Energy required for "Small Multi-functional Manufacturing Platform": 200 points

REQUIRED MATERIALS: 1000KG OF METAL RAW MATERIALS, 20KG OF RUBBER

Manufacturing time: 1H

FLOOR AREA: 2 M LONG, 1.5 M WIDE, 2.3 M HIGH

Description: According to the multi-functional manufacturing platform transformed from the machining center, after retaining some points of the machining center, the processing capacity of complex parts is increased and the manufacturing speed is increased.

Power: 30KW

Processing size: 1000 mm

Unfolded 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, it was already nine o'clock in the morning.

Then click on manufacturing, looking at the nano core that was working, Lu Chen left the processing room, and then came to the bedroom to contact the remaining two traders to determine the trading time.

......

An hour later, with the connection with the nanocore, Lu Chen knew that the multi-functional manufacturing platform nano worm nest had been manufactured, Lu Chen came to the nano core, took out the silver-white small ball-like nano worm nest, came to the open space on the side, started the nano worm nest and threw it on the ground, and then the nano worm nest began to expand,

Lu Chen looked at the time, anyway, it would take an hour to fully unfold and form, plus the infrastructure maniac was about to arrive, and he could prepare to trade items.

......

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

Lu Chen spent a lot of time transporting metals and building materials into the shelter, and then Lu Chen lay on the sofa in the living room thinking that if he was alone every time these things were moved, there was no way to transport some large materials by himself, so Lu Chen was thinking about ways to rest while lying on the sofa

"The best way is to use the nanocore to build a robot out, because of the connection with myself, I can direct it directly in my mind, but in this case, the energy consumption is estimated to be a lot, and now many facilities in the shelter need to be transformed, and only 240 points of energy can be collected in a day, the energy gap is very large, so I will not consider it for the time being, and put it in the alternative;

Secondly, you can use the knowledge you have learned to process parts to manufacture robots, so that you only need a small amount of energy to manufacture key equipment to manufacture the corresponding parts, and then you can manufacture them in batches, the advantage is that there is no shortage of manpower behind you, but there are also shortcomings, energy consumption is estimated to increase, and the electricity generated by the small geothermal generator in the shelter is estimated to be stretched, so you have to increase the power generation equipment, and you have to enter the supporting program, but you can produce a micro nano nest to assist in control,

However, my current knowledge reserve is insufficient, and I can't build a robot for the time being, and at my current learning progress, if I only specialize in robot knowledge, I can almost build a simple robot in a month to assist my work."

Lu Chen thought of this and suddenly thought of seeing in the news that there was a simple exoskeleton device in the army before, which can greatly improve the strength of the human body and carry heavy materials, when I saw that it said that after wearing it, it originally took four people for a box, but now it only needs two people, thinking of this, Lu Chen felt that it was good to use this method first, and then Lu Chen sat on the sofa and opened the nano core to start designing.

"First of all, the drive method can use hydraulic pressure and motor, but I am going to put a high-energy battery in the back position, so that the motor can be used to drive, the power can be larger, and the second is the support part, which is made of high-strength alloy, and then the control program uses micro nano nest control."

Then Lu Chen thought that he had heard the statement of graphene batteries before, and then found out the information and looked at it, and found that the ability of the nanocore can make graphene batteries, but it is necessary to find an efficient power storage structure, so that by using the rapid charging and discharging characteristics of graphene and the large-capacity power storage structure, there is no need to worry about the problem that the exoskeleton has a short battery life, and this battery can be used to create vehicles with a long range, including other equipment.

Then Lu Chen began to look for large-capacity battery information on the Internet, and found that most of the new battery technologies are some theoretical data, and there are no specific experimental data, Lu Chen looked on the Internet for a while and found no new discoveries, so he could only use the battery technology in his own distribution room, although the energy storage of the battery pack in his distribution room is very high, but it occupies a large area, and finally Lu Chen thought about it for a while, and decided to use the structure of ordinary batteries first, and then add graphene technology to make it have the ability to charge and discharge quickly.

"But for the time being, I'm not in a hurry to make it, and I'll have to wait a few days to renovate the nest before doing this."

After Lu Chen made a memo, he looked at the time and saw that it was not early, it was almost 12 o'clock, so he walked to the processing room to take a look, and found that another heater had been manufactured, and the remaining materials were being made The last one, Lu Chen took out the manufactured heater and put it next to the two heaters that had been made before, and then ran to the kitchen to cook.

After eating, it was almost one o'clock in the afternoon, and after getting in touch with the mechanic and determining the time of arrival, Lu Chen came to the edge of the multi-functional processing platform, prepared the materials, and began to make the parts of the crossbow, almost two hours later, Lu Chen finished making all the parts and 30 crossbow arrows, and then came to the side of the assembly table to start assembling the crossbow.

After the crossbow was assembled, Lu Chen came to the outside of the shelter with a few crossbow arrows, aiming at a tree ten meters away and firing, only to see that after the crossbow arrow hit the tree, the crossbow arrow sank into a depth of nearly five or six centimeters, Lu Chen nodded with satisfaction when he saw this effect, and then Lu Chen put 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 a second-hand pickup truck to be traded to Lu Chen, and then the two got to know each other and completed the transaction.

Seeing Wang Xingyi drive away, Lu Chen drove the pickup into the garage, and then Lu Chen took out a miniature nano worm nest and put it on the car.

After the inspection, Lu Chen also roughly knew the specific performance of the car now.

The load has been increased from 0.5 tons to 1.5 tons, and the fuel consumption has 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 vehicle being optimized, but the focus is still on the load and power, after all, Lu Chen is ready to drive to find materials, and the comfort is almost on the line, which is also consistent with the optimization direction set at the beginning.

Lu Chen calculated that the fuel consumption of 100 kilometers was 15 liters, and the diesel fuel he had prepared for the diesel generator was more than 400 liters, and it could still be used for a long time to search for supplies in this city for the time being.

Then Lu Chen closed the door and entered the shelter, ready to design it to see how the water system is transformed, after all, it is now the official water supply, but after the cold and the ground freezes, the pipe will either be broken, or the inside will be frozen and blocked, and then if you try to get water, you will already eat it, and now it will be transformed first, and it will not be passive in case of a situation in the future

Lu Chen looked at some cases of water collection systems on the Internet for a while, combined with the actual situation of the shelter, prepared to drill a well downward, and then prepared a 10-ton water storage tank, prepared a small water collector, and connected the pipe to the outside, when it rains, rainwater can be collected, and the rainwater can be used to provide water to the plant cultivation room, which can save domestic water.

Therefore, Lu Chen planned to spend the last few days planning and renovating the shelter first.

Subsequently, after eating dinner, Lu Chen came to the bedroom and began to plan the tasks for the next few days

"First, first of all, water resources, because I am located in the south, there are still more underground water systems, you can drill a well, and at the same time, in order to avoid accidents, you must have a water tank, plus pipes to the kitchen and bathroom and other places, plus filtration devices;

Second, after the source of water is solved, it is necessary to strengthen security, the main structure of the shelter itself has been reinforced, and now the materials are sufficient, the gate can also be reinforced, and the houses on the ground should also be reinforced, and the safety of the houses on the ground should be strengthened and heating facilities can be installed;

The third is the plant culture room, in order to survive and quality of life in the future, must be expanded, now I live alone, the people around me are either demolished and moved, or into the official shelter, I can expand to the surrounding places, and then need other functions can be expanded downward, fruits can be exchanged with materials and plum plants, so I need at least one acre of area to plant crops, which is converted to about 666 square meters, but I am a high-yield rice seed, with a yield of about 1600 catties per mu, Even if the yield is reduced, the yield of 1200 catties can be guaranteed, so about 600 square meters can be separated, half is planted with rice, half is planted with vegetables, plus temperature and humidity control, you don't need to consider the season, and I also checked it on the Internet, if adults consume rice a year, 500-600 catties is enough, and the rest can be used to exchange fruits, meat and other materials. ”

Lu Chen thought about it for a while and continued to write in his notebook:

"The fourth is the safety of going out, it is not too cold outside, but the temperature outside will definitely drop below zero in another month, so it is necessary to consider making some cold-proof clothing, and although the country has zero tolerance for illegal crimes, but this situation also has not been taken care of, I also have to prepare some self-defense weapons, the crossbow made before is still a little insufficient, only one crossbow arrow can be fired at a time, the firepower is a little weak, the crossbow on the Internet can only find information, and the specific production process is still relatively difficult to find."

Thinking of this, Lu Chen felt a little pity, if he got the nano core earlier, then many equipment could be directly manufactured without having to buy it, and he could directly find a way to copy it and master its structure, and he could directly manufacture it, if he didn't want to only have drawings, the consumption would be much greater, and many devices could not find drawings on the Internet, and could only be deduced based on theoretical knowledge, which would consume a lot of energy and a lot of time.

Perhaps because the nano core can independently gather energy after binding to itself, Lu Chen recently found another function in the core, that is, if there is theoretical support, then the core will consume different energy according to the completeness of the theory to make corresponding items, such as Lu Chen's most wanted high-performance energy storage battery, lithium-ion batteries and sodium-ion batteries that have been said on the Internet, if Lu Chen inputs theoretical knowledge, the nano core deduces the night theory according to the completeness of the theory, and consumes different energy. After it is perfected, it can consume energy to make items, and it can also consume energy again to deduce the equipment that makes batteries, but if there is a complete physical object, then it can be made by directly consuming energy, so Lu Chen felt a little regretful

"Since you want to use a repeater, it is better to directly produce thermal weapons in one step, although the most advanced firearms only know the structure, there are no detailed drawings, but the drawings of bolt-action rifles and semi-automatic rifles decades ago have been declassified, and the online drawings can be found casually, so simply make a gun, but firearms need bullets, although I don't have so much copper, but my country uses a steel core bullet, and the outside is plated with a layer of copper, so the bullet shell is there, but what about gunpowder"

Lu Chen thought of this and had another headache, this went around and around or returned to the original point, if you use hot weapons, materials and processes are lacking, although you can consume energy to deduce, but now there is also a shortage of energy in other places, so in the end, you can only choose to make cold weapons first.

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

Lu Chen suddenly had a flash of inspiration, if he can make a high-energy battery, then according to the electromagnetic principle, can he make an electromagnetic gun?

Then Lu Chen smiled bitterly, it's all energy, it's too lacking, think about what to do now

"As for self-defense weapons, let's use crossbows for the time being, and see if we can find the design of the repeater on the Internet

The fifth point is to go out to collect supplies, I now have a pickup, but the pickup itself is not large, and the space is limited, I have to prepare a large load vehicle at will, this will be said later, but the pickup has been transformed after the horsepower has become stronger, I can make a simple trailer body to hang behind the pickup, and then install a small boom behind the pickup, at least a ton of items can be dropped, so that the heavy items can be directly transferred to the back of the trailer body, and the light one I can move myself, Especially those building materials, which can save a lot of effort and time."

Writing this, Lu Chen can only take into account these aspects for the time being, let's talk about special circumstances later, and then Lu Chen looked at the time, went to study for a while and then rested.
