My Black Tech Shelter

That night, Lu Chen returned to the shelter. He didn't gain much this time. After all, due to the policies of Dragon Country and the cohesion of the nation, a large part of the materials in the city have entered the official shelter.

In addition, the official organized another material collection after the meteorite fell. Now there are no materials in the city except some reinforced concrete houses.

So Lu Chen planned to start learning knowledge in seclusion after searching for materials this time, and then accumulate energy to upgrade the shelter.

At the same time, he started trading with the official after the vegetables matured, and he could also use the technology of nano core energy deduction as an exchange. However, he didn't have any connections in the official at present, and others would not believe in his technology.

So he could use some vegetables and fruits for exchange in the early stage. Lu Chen planned to open a planting room after the energy was sufficient, and then plant low-altitude fruits such as grapes.

During the few days that Lu Chen was in seclusion, the nationwide clearance strategy had achieved remarkable results. A large number of illegal armed gangs were eliminated, ensuring the normal security of various regions.

At the same time, the official trading area also began to operate. Many shelters that could not survive due to rapid environmental changes exchanged a lot of survival supplies from the official, which enabled them to upgrade and transform the shelters and strengthen their own survival capabilities.

In addition, the construction of various production bases under official shelter is almost coming to an end. The planting and breeding bases that are automatically managed by the Fuxi artificial intelligence of the Longke Institute have begun to operate normally. After the first batch of livestock is slaughtered and the grain is mature, it will be promoted to the whole country.

At the same time, the losses of the Sun Country and the Stars and Stripes Country where the meteorite fell before have been counted. Among them, two-thirds of the land of the Sun Country is no longer viable, and all underground shelters in the affected areas have lost contact. It is estimated that they are in great danger.

In addition, half of the land of the Stars and Stripes Country has been affected by the eruption of the Yellowstone Park volcano. The surface is no longer suitable for human survival. In addition, the frequent addresses in the area where the volcano erupted have caused a large number of shelters to be destroyed, and the people have to leave the shelters and flee to other areas.

At the same time, in Longguo, the Capital Environmental Monitoring Center, the alarm suddenly sounded. The staff hurriedly checked the situation and found that there was an extremely cold air moving southward from the north, which was approaching the border of Longguo. The staff immediately reported it, and it was sent to the commander-in-chief's desk not long after.

Then the relevant departments were convened to discuss the impact of the extremely cold air moving southward on my country. With the explanation of experts and scholars, everyone learned that according to previous calculations, if there was no southward movement of this cold air, then the average temperature in my country would drop to about minus 20 degrees one month after the meteorite landed, and reach about minus 50 degrees two months later.

However, with the southward movement of this cold air, the temperature will drop directly to below minus 50 degrees in 10 days. If in addition, with the arrival of winter, the final temperature will remain at about minus 70 degrees, so the situation in the future is not optimistic.

Then, the commander-in-chief asked all departments to pass on this news, and at the same time instructed the Longke Institute to speed up the development of controlled nuclear fusion, and shelters in various places should take insulation measures to ensure the safe and orderly operation of shelters.

In the next 10 days, Lu Chen did not go out to look for supplies, nor did he use the energy of the nano core. Instead, he calmed down and continued his studies.

Through these 10 days of study, Lu Chen's brain had been redeveloped, and he basically completed the basic courses of the university. In fact, it was not considered learning, but just consolidating his knowledge.

Now Lu Chen can continue to learn more advanced knowledge on this basis. At the same time, as of 10:00 on June 20, the energy in the nano core has accumulated to 2880 points of energy.

After Lu Chen got up, he looked at the energy of the nano core and felt that he could do a lot of things.

First, his power system can be upgraded. Consuming 1000 points of energy can upgrade the small geothermal generator to a medium-sized geothermal generator set, which can achieve the original goal of 2 megawatts of power. This power can generate 2000 degrees of electricity per hour, which is enough for him to use for a long time.

Then spend 1000 points of energy to start deducing a higher level of high-energy battery based on graphene high-energy batteries. The goal is to be able to store 1000 degrees of electricity, so that the vehicle can be directly transformed to achieve full electric drive.

Finally, we will wait until tomorrow to upgrade the manufacturing room and realize a fully automated workshop, where we can directly input drawings for fully automatic production.

Then, Lu Chen spent 1,000 energy points to create a nano insect nest and put it on the small geothermal generator. Then the nano core started to start, and then the power inside the shelter was instantly switched and began to use backup energy.

The shelter entered a low-power state. Then, after the small geothermal generator set was upgraded to a central generator set, the power was switched to the main power operation under the control of the intelligent program, and the facilities in the shelter began to enter normal operation.

After watching the geothermal generator enter normal operation, Lu Chen checked around and left the power distribution room after finding no problems.

Then Lu Chen turned on the nano core, selected graphene high-energy battery in the deduction column, input 1,000 energy points, and started deduction. Lu Chen looked at the time and found that it would take about five days to complete the deduction. Then Lu Chen didn't care about it anymore and continued to retreat.

The next day, Lu Chen was awakened by a burst of alarms and found that it was the central intelligent program that was alarming. Then Lu Chen turned on the intelligent program and found that the content of the alarm was related to the environment.

The information prompt detected a major change in the external environment. The external temperature continued to drop in a short period of time, which triggered the warning value set by Lu Chen in the program, so an alarm was generated.

Then Lu Chen logged into the official website of Tingcheng Shelter and found a government announcement pinned to the top. The content was that a cold air from the north had arrived in our country. Experts predicted that the temperature would drop to minus 50 degrees within ten days.

At the same time, official shelters have opened exchange channels for insulation materials and coal. If private shelters know that they cannot withstand such low temperatures and do not want to enter official shelters, they can exchange insulation materials and coal resources at the trading place.

Later, Lu Chen discovered that the temperature in the shelter had dropped by 2 degrees. This was the value after intelligent program control, and it was only in the bedroom, living room, and plantation. In other areas, the temperature had dropped to more than ten degrees.

Lu Chen thought for a while and went to the power distribution room. He dismantled the biogas generator and re-laid the pipes. He spent 500 energy points to build a small boiler and used biogas to heat the boiler to ensure that the temperature inside the shelter was normal.

He spent another 100 energy points to enhance the warmth function of the protective clothing. Finally, looking at the remaining 500 energy points, Lu Chen first spent 200 energy points and building materials to expand the original growing room to 400 square meters.

Cabbage, lettuce, and tomatoes were planted again on the extra land. Then, Lu Chen used the remaining 300 energy points and building materials to open a new growing room next to the growing room with an area of ​​300 square meters.

After plowing the land inside and adding water, Lu Chen took the rice seeds and started cultivating seedlings, preparing to use this growing room as a planting base for food rations.

After doing all this, Lu Chen continued his retreat journey.

——

Five days later, as the research on high-energy batteries was completed and a lot of energy was accumulated, Lu Chen began to modify his outfit for going out, because the vegetables would be ripe in a few days, and it was so cold outside that his car might not start anymore. Therefore, vehicles and protective clothing must be modified before the vegetables mature.

Then Lu Chen looked at the newly developed high-energy battery

——

Graphene lithium-ion battery

Manufacturing requirements: 100 energy points/50 energy points (graphene battery provided)/kg

Energy density: 200WH/g

Description: A high-energy battery developed with graphene battery technology has an energy density of 200wh/g. Its unique graphene technology brings fast charge and discharge capabilities that can release and charge a large amount of electricity in a short time, which can provide Electrical equipment provides large amounts of power (and may be directly overloaded).

——

Lu Chen took a breath when he looked at the battery. The thousand points of energy were so worth it. You get what you pay for. Each kilogram of the battery contains 200 kilowatt-hours of electricity.

This means that if you make a ten-kilogram battery, it will contain 2,000 degrees of electrical energy, which is ten times more dense than the previous one.

Then, Lu Chen saw that there were 1,200 points of energy in the nanocore, and then used 200 points of energy to modify it based on two graphene batteries. The energy of the battery reached 800 degrees, and at the same time, he used 500 points of energy to transform the outside of the protective suit. High-strength fiber materials have been upgraded to high-strength alloy materials.

At the same time, the protective clothing is no longer bulky like a space suit, but has become similar to the acceleration armor in the movie. The high-strength fiber material inside becomes the lining, which strengthens the shock-absorbing device inside the armor. ,

At the same time, the battery is integrated into the interior of the armor, also on the back of the armor, but now it is protected by the armor.

Lu Chen planned to save the remaining 500 energy points for a few more days, and when he had enough energy, he would start to modify his car from using fuel to using electric energy.

——

A few days later, on the last day of June, Lu Chen woke up in the morning and saw the panel outside the plantation showing that the first batch of vegetables was ripe.

Lu Chen took the sack and started to enter the plantation to harvest. In the end, he left 50kg of cabbage and 10kg of lettuce for himself to eat. The rest was harvested and put into sacks to be traded at the official shelter.

After Lu Chen loaded the dishes, he found that the energy of the nano core had reached 1,500 points, and he could transform the vehicle.

Lu Chen came to the garage and used 1,000 energy points to create a modified nano-hive. After it was built, he put it in the car and started it. The modification started. Lu Chen saw that it would take some time, so he went to have lunch first.

In the afternoon, after Lu Chen finished eating, he came to the garage and found that the car had been modified. The modified vehicle was similar to the Ford Raptor, but it was more aggressive than the Raptor. The rear compartment had become a fully enclosed one. , the front became a double-row four-seater, and the floor became much higher.

Moreover, the strength of the tires feels higher than ordinary tires. Lu Chen estimates that they are similar to run-flat tires. The entire car frame has also been strengthened, the load capacity has reached 5 tons, and the power of the car has been increased to about 500 horses. Looking at the big monster in front of him, Lu Chen nodded with satisfaction. The only thing he needed now was the battery.

At ten o'clock in the evening, Lu Chen had 600 energy points in his hand, and he directly used up the energy to start integrating the battery. Then Lu Chen installed the battery in the car and started charging.

1400 degrees of electricity is enough to drive this beast to run more than 600 kilometers at full load, and the internal insulation and heating are done to the extreme, which can ensure that the temperature inside the car is not lower than 15 degrees in an environment of minus 70 degrees.

With the internal oxygen supply device, it is equivalent to a small transport vehicle in the movie, but the space may not be that large.

After Lu Chen looked at everything, he loaded all the vegetables into the back compartment, closed the door and went back to sleep. He had to get enough rest because he had to go to trade tomorrow.
