Lu Chen hid in the safety compartment, and with a violent vibration, the entire safety compartment was shaking violently, as if it was about to crack in the next moment, and Lu Chen could hear the sound of the metal bracket breaking. After feeling it for a long time, the vibration finally stopped, and Lu Chen hurriedly came out of the safe warehouse and breathed heavily

"I feel like I'm almost suffocated, this one has to be improved, and the oxygen supply has to be added later,"

Because it is a temporary safety warehouse, even if it is a large iron box fixed on the ground, I didn't expect to almost suffocate myself

After Lu Chen slowed down for a while, he found that the inside of the shelter had been cut off, and it was pitch black, Lu Chen walked to the bedroom in the dark, took out a flashlight from the bedside table, and began to walk towards the power generation room, ready to switch the power supply and restart the power generation equipment

Lu Chen walked to the power generation room, first disconnected the external power supply equipment, then started the battery pack to supply power, first turned on the lighting facilities inside the shelter, and after turning it on, Lu Chen found that the situation was worse than he imagined.

Because the meteorite hit nearby, causing strong vibrations, there is now a partial collapse of the power distribution room, and the generator is buried by the collapse right on the side, and it is estimated that it is unusable.

"I didn't expect it to be like this, since this is the case, it's better to put it in place at one time, directly replace it with a geothermal generator set, and make large-scale power storage equipment,"

Lu Chen looked at the power generation room in front of him, which was one-third smaller, and felt that since it was already like this, he could directly use the nano core to make geothermal power generation in place at one time.

Subsequently, Lu Chen went to the warehouse, took out the nano core, entered the manufacturing interface and began to manufacture the equipment

"Name: Small geothermal generator set;

Manufacturing requirements: energy 200 points, iron 500KG, copper 100KG, rubber 10KG,

Performance: 200 kW per hour

Description: The small geothermal steam turbine generator set optimized by using nanocore is inefficient, but the maintenance requirements are greatly reduced after being manufactured with nanocore."

。。。。。

Name: Small and efficient solid-state power storage equipment

MANUFACTURING REQUIREMENTS: ENERGY 100 POINTS, 200KG OF IRON, 50KG OF COPPER, 3KG OF LITHIUM

Performance: 1,000,000 KWH can be stored

Description: Don't look at me small, but I can eat it, the most efficient solid-state power storage equipment, although it is also a low-level facility, but it is better than liquid lithium batteries"

Lu Chen found these two kinds of power generation and power storage equipment in the nano core, ran to the warehouse, used the nano core to create two nano worm nests, and then took the nano worm nest to the power generation room, one was placed on the side of the original generator, and the other was directly placed on the power storage facility

Lu Chen gave priority to starting the geothermal nano hive, only to see that the center was the origin after starting, the nano hive began to expand, and at the same time, the buried generator began to be devoured and revealed, at the same time, I saw the nano hive stretch out a probe arm and began to punch holes in the ground, and there was constantly a silver liquid extending downward, after about half an hour, the nano hive ended, and a small geothermal generator appeared in front of Lu Chen,

Then Lu Chen started the power storage nano worm nest, and after unfolding, he devoured the original power storage equipment, and a larger device appeared in the original place, Lu Chen then started the generator, and in an instant, all the equipment inside the shelter was running, and the excess power flowed to the power storage equipment, and the charging light on the power storage equipment began to flash, showing that it was in a charging state,

Then after seeing that the power system was normal, Lu Chen began to check the situation of the other facilities inside the shelter,

After inspection, Lu Chen found that the condition of his shelter was a bit bad, first of all, there were damaged places in the ventilation pipes, which needed to be repaired, and then there were many landslides, which needed to be re-excavated and reinforced, and after inspection, it was found that the main structure of the shelter was also very damaged

Then Lu Chen made two nano worm nests through the nano core, one was used to repair the main body of the shelter structure, and the other was used to repair the ventilation system, and then because of the energy exhaustion, the nano core entered a dormant state, and then Lu Chen put one of the nano worm nests into the ventilation system and one on the wall.

After Lu Chen's nano-insect nest operated on its own, he was ready to go out and take a look, after all, a meteorite fell nearby, and he had to see how the situation was.

Lu Chen opened the door and found that the sky was gray, and the edge of the city in the distance had become a big pit, and the edge was still burning, but the sound of a fire truck was heard in the distance, and it was estimated that the fire brigade in the city had begun to carry out firefighting operations, but many places in the city were burning, a scene of apocalypse, and it was estimated that the fire brigade was also a drop in the bucket

At this time, Lu Chen's mobile phone rang, it was the official text message push, and the general content was

"Because of the impact of meteorites, global volcanic eruptions and the reduction of sunlight due to the dense particles in the universe, the earth will usher in an ice age of tens to hundreds of years, reminding the general public to rush to shelters in time to take refuge, and at the same time, individual and corporate shelters should increase the collection of materials to ensure that they can better survive,"

Lu Chen looked at the gray sky, turned around and entered the shelter, and closed the door.

Lu Chen came to the studio, looked at the 3D printer in front of him and fell into deep thought

"Now that the nanocore has entered a dormant state, it could have slowly recovered its energy by irradiating the sun, but now because of the obscuration of volcanic ash, the nanocore can only absorb the free dark energy in the air every day to replenish, and the efficiency is too slow, and many things can only wait."

Lu Chen looked at the nanocore

"Nano core

Energy: 0

Recovery rate: 10/h

Function: According to the user's needs, select the corresponding drawings, use energy and materials to create nano worm nests, and form related equipment after unfolding in the open space, this process is irreversible"

Lu Chen looked at this interface, calculated that it was 240 points of energy a day, and the previous reserves of 360 points of energy were used up, and if you want to do anything else, you can only wait until tomorrow, the power generation and storage equipment is 300 points, plus 20 points for repairing ventilation equipment, and 40 points for repairing and reinforcing the main structure

"However, now many equipment needs to be upgraded or transformed, and it is not realistic to rely on nanocores alone, after all, the energy recovery is too slow, and it can only be used in some key facilities,"

"Maybe I can transform the 3D printing equipment, so that I can print parts and assemble many devices by myself, although it is not as good as the nano core manufacturing, but it is more convenient, and the emergency or transaction is also good"

Considering that after the transformation of the 3D printer, many things will not be manufactured without nanocores, which can save a large part of the energy, and only need to use electricity.

Then, Lu Chen looked at the transformation conditions of the printer,

"Industrial-grade 3D metal printers

Printing range: Metal

Power: 10 kW

Transformation direction: industrial-grade 3D printer - composite 3D printer

Retrofit Attributes:

Print range, metal, polymer

Power: 15 kW

Transformation Cost: 100 Energy Points

Looking at this consumption, Lu Chen said that it is still acceptable, after all, the energy consumption is reduced and the printing range is expanded, so that many things can be printed.

Lu Chen thought that the frequent eruptions of volcanoes in the back were estimated to lead to frequent earthquakes, so the main structure of the shelter still had to be strengthened to prevent such a situation from happening again today.

Subsequently, Lu Chen found a way to strengthen the main body

"Special nano-hives

MANUFACTURING COST: 100 ENERGY, METAL 1000KG

Description: The specially made nano worm nest, after the set range, can enter the wall and the foundation, and transform the steel bar in the wall and foundation from the nano level, strengthen the density, strength and toughness of the steel bar, and strengthen the wall solidity and increase the wall hardness. ”

Lu Chen felt that this could meet the requirements for now, and when the energy was abundant, he could add another layer of alloy walls to it.

"100 points to transform the printer, and 100 points to the special hive, a total of 200 points of gap, can only wait until tomorrow"

Lu Chen looked at the dazzling 0 on it and thought helplessly.

"Forget it, log in to the forum first to see how they are!"

Lu Chen had previously joined a local forum to communicate with a group of people who had set up a personal shelter

Fruit farmer: "The meteorite just landed nearby, is everyone okay?" Still bubbling up."

Mechanic: "It's okay if I'm far away from here, and everyone else is okay?" ”

Infrastructure maniac: "It's a little closer to me, but when I built it, the strength was high, so there was no big problem"

Xiao Transparent: "It's really the blessing of the ancestors, I almost hung up, and now the shelter is almost destroyed, my side has already asked the official for help, and I will go to the official shelter later, and everyone will have a period later." ”

I saw that not long after the forum Xiao Transparent was posted, it went offline, and it was probably packed up

Lu Chen replied in the forum:

Struggling rice worm: "It's okay on my side, it's just a little loss, but I've dealt with it." ”

Lu Chen chatted with a group of people in the forum

Suddenly, the infrastructure madness said: "I heard that the official said that it is about to enter the ice age, the global temperature is decreasing, are you ready for heating equipment, who has extra equipment, I have a lot of building materials to exchange with him"

Looking at the words of the infrastructure madman in the forum, everyone was silent for a while,

Fruit farmer: "I don't have any preparation here, I can also exchange, I have a lot of fruits on my side, I can exchange them with fruits,"

Mechanic: "Although I have heating equipment, I bought it before, and it is only enough for my own family, and the heating equipment consumes a lot of electricity, so you have to think about whether you have enough electricity."

Lu Chen saw this and looked for it in the nanocore, and saw such a heating device

。。。。

Small heaters

MANUFACTURING REQUIREMENTS: ENERGY 50 POINTS, METAL 10KG

Power: 5 kW

Applicable space: 100㎡

Description: Small heating equipment, don't expect it to bring you much warmth, only to ensure that you don't freeze to death

。。。。

Lu Chen was a little speechless when he saw the above introduction, but this is also a more practical equipment at this stage, and putting two at home can also ensure that this winter that lasts for decades will no longer be cold

Lu Chen saw this and replied on the forum, "I can make simple heating equipment here, but the power is not high, and the maximum temperature can only be guaranteed to be 100 square meters, but the comfort is not very good, and it can still be guaranteed to be at a comfortable temperature in the bedroom."

As soon as Lu Chen's words were sent, he received private messages from fruit farmers and infrastructure freaks,

Fruit farmer: "Rice worm, I can exchange fruit with you here, and I will exchange 100 catties of fruit for one"

Infrastructure maniac: "Rice worm, I still have a lot of infrastructure materials and metal raw materials on my side, you see how you can exchange them over there"

Lu Chen looked at these private messages, thought for a moment and replied:

"Fruit farmer, I agree to your exchange conditions, but you need to come by yourself, I don't have transportation here, I can't go to your side"

"Infrastructure maniac, I need 500KG of metal raw materials here, I need you to transport them over for trading, I can't go now"

The infrastructure maniac here thought about it when he saw the reply, and replied to Lu Chen: "I will give 1 ton of metal raw materials, and I will replace two units"

The same reply from the fruit growers is also ready to replace two units.

At this time, the mechanic found Lu Chen: "I want 3 here, I have a second-hand pickup truck here, eighty percent new, can you take a look?" ”

Lu Chen immediately agreed when he saw this, after all, it was still very inconvenient for him to have no transportation, so he agreed to the transaction.

Lu Chen replied in private messages one by one: "My side can only start manufacturing heating equipment tomorrow, and about 3 units can be made a day, so the fruit farmer, you come to pick it up tomorrow morning, and you come to pick it up the morning after tomorrow, and the mechanic can only wait until the day after tomorrow,"

Looking at Lu Chen's reply, everyone was quite satisfied, and Lu Chen went offline after chatting a few words.

Lu Chen looked at the time, it was already six or seven o'clock in the evening, Lu Chen ate something, studied knowledge for a while and then went to sleep.
