 Lu Chen hid in the safety cabin. With a violent vibration, the entire safety cabin was shaking violently, as if it was going to crack at the next moment. Lu Chen could hear the sound of the metal brackets breaking. After what felt like a long time, the shaking finally stopped. Lu Chen quickly came out of the safety cabin, breathing heavily.
 "I feel like I was almost suffocated to death. This needs to be improved, and oxygen supply needs to be added later,"
 Because it was a temporary safety warehouse, even a large iron box fixed on the ground, I almost suffocated myself to death.
 After Lu Chen calmed down for a while, he found that the power inside the shelter had been cut off and it was pitch dark. Lu Chen walked to the bedroom in the dark, took out the flashlight from the bedside table, and started to walk to the power generation room, preparing 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, and then started the battery pack to provide power. First, he turned on the lighting facilities inside the shelter. After turning it on, Lu Chen found that the situation was worse than he thought.
 Because a meteorite struck nearby, causing strong vibrations, part of the power distribution room collapsed. The generator was buried by the landslide just on the side, and it is estimated that it cannot be used.
 "I didn't expect it to be like this. Since it's like this, it's better to do it all at once, directly replace it with geothermal power generation units, and manufacture large-scale power storage equipment."
 Lu Chen looked at the power generation room in front of him, which was one-third smaller. He felt that since this was already the case, he could directly use nanocores to create geothermal power generation in one go.
 Afterwards, Lu Chen went to the warehouse, took out the nano core, entered the manufacturing interface and started manufacturing equipment.
 “Name: Small geothermal power generation unit;
 Manufacturing requirements: 200 energy points, 500KG iron, 100KG copper, 10KG rubber,
 Performance: Generate 200 kilowatts per hour
 Explanation: The small geothermal steam turbine generator set optimized using nano-core is inefficient, but after being manufactured with nano-core, maintenance requirements are greatly reduced,"
 . . . . .
 "Name: Small and high-efficiency solid-state power storage equipment
 Manufacturing requirements: 100 energy points, 200KG iron, 50KG copper, 3KG lithium
 Performance: can store 1 million KWH
 Explanation: Although I am young, I can eat it. The most efficient solid-state power storage equipment, although it is also a low-level facility, is better than liquid lithium batteries."
 Lu Chen found these two power generation and storage devices in the nano core. He ran to the warehouse and used the nano core to create two nano insect nests. Then he took the nano insect nests and walked to the power generation room. One was placed in the original generator. On the other side, the other one is placed directly on the power storage facility.
 Lu Chen prioritized the activation of the geothermal nano-insect hive. After activation, the center was the origin, and the nano-insect hive began to expand. At the same time, the buried generator began to be swallowed up and exposed.
 At the same time, the Nano-Insect Hive stretched out a probe arm and began to drill holes into the ground, and silver liquid continued to extend downward. After about half an hour, the Nano-Insect Hive ended its expansion, and a small The geothermal generator appeared in front of Lu Chen,
 Then Lu Chen activated the power storage nano-hive, which expanded and swallowed the original power storage device. A larger device than before appeared in its place.
 Lu Chen started the generator. In an instant, all the equipment inside the shelter started running. The excess power flowed to the power storage equipment. The charging light on the power storage equipment began to flash, indicating that it was in a charging state.
 After seeing that the power system was back to normal, Lu Chen began to check the conditions of other facilities inside the shelter.
 After inspection, Lu Chen found that the condition of his shelter was a bit bad. First, the ventilation ducts were damaged and needed to be repaired. Then there were many landslides that required re-excavation and reinforcement. In addition, after inspection, he found that the main structure of the shelter had also been damaged a lot. Major damage. If left unchecked, another shock will probably disable the entire shelter.
 Lu Chen then used the nano core to create two nano insect nests. One was used to repair the main structure of the shelter, and the other was used to repair the ventilation system. However, due to exhaustion of energy, he could no longer create nano insect nests.
 Lu Chen put one insect nest into the ventilation system and the other into the wall.
 After Lu Chen's nano-worm nest was operating on its own, he was ready to go out and take a look. After all, a meteorite fell nearby, so he had to see what happened.
 Lu Chen opened the door and found that the sky was gray. The edge of the city in the distance had turned into a big pit, and the edge was still burning. However, the sound of fire trucks could be heard in the distance. It was probably the fire brigade in the city starting to put out the fire. , but many places in the city are burning, and it is a doomsday scene. It is estimated that the fire brigade is only a drop in the bucket.
 At this time, Lu Chen's phone rang. It was an official text message. The general content was:
 "Due to the impact of meteorites, global volcanic eruptions and the density of particles in the universe, which reduces sunlight, the earth will usher in an ice age of tens to hundreds of years. The general public is reminded to rush to shelters in time. At the same time, personal and corporate shelters should be Increase the collection of supplies to ensure that you can survive better,"
 Lu Chen looked at the gray sky, turned around and entered the shelter, closing the door.
 Lu Chen came to the workroom, 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 restored energy by irradiating the sun, but now due to the obstruction of volcanic ash, the nanocore can only absorb free dark energy in the air to replenish it every day. The efficiency is too slow, and many things can only Can wait”
 Lu Chen looked at the nano core
 "Nano Core
 Energy: 0
 Recovery rate: 10/H
 Function: According to user needs, select the corresponding drawings, use energy and materials to manufacture nano nests, and after unfolding in the open space, relevant equipment can be formed. This process is irreversible."
 Lu Chen looked at this interface and calculated that it was 240 points of energy a day. The 360 ​​points of energy stored before were all used up. If he wanted to do other things, he had to wait until tomorrow. The power generation and storage equipment were 300 points, plus 20 points for repairing ventilation equipment, and 40 points for repairing and reinforcing the main structure. All of them were used up.
 "But now many equipment need to be upgraded or modified. It is not realistic to rely solely on nano cores. After all, energy recovery is too slow and can only be used on some key facilities."
 "Maybe I can modify the 3D printing equipment, so that I can print parts and assemble many equipment by myself. Although it is not as good as the one made with nano cores, it is convenient and good for emergency or trading."
 Considering that after the 3D printer is modified, many things do not need to be made with nano cores, which can save a lot of energy, and only electricity is needed. Although it still consumes materials, energy Points are hard to come by, so we should consume as little as possible.
 Lu Chen looked at the printer's transformation conditions,
 "Industrial 3D metal printer
 Printing range: metal
 Power: 10 kilowatts
 Transformation direction: Industrial 3D printer-composite 3D printer
 Attributes after transformation:
 Printing range, metal, polymer
 Power: 15 kilowatts
 Transformation consumption: 100 energy points"
 Looking at this consumption, Lu Chen said that it was still acceptable. After all, it reduced energy consumption and expanded the printing range, so that many things can be printed out.
 Lu Chen also thought that frequent volcanic eruptions in the future would probably lead to frequent earthquakes, so the main structure of the shelter still had to be reinforced to prevent the situation like today from happening again.
 After a while, Lu Chen found a way to reinforce the main body
 "Special nano insect nest
 Manufacturing consumption: 100 energy points, 1000KG metal
 Description: The specially manufactured nano insect nest can enter the wall and foundation after the range is set, and transform the steel bars in the wall and foundation from the nano level, strengthen the density, strength and toughness of the steel bars, and at the same time strengthen the wall solidity and increase the wall hardness. "
 Lu Chen felt that this could meet the requirements for now. When the energy is sufficient, he could add another layer of alloy wall inside.
 "100 points for printer modification and 100 points for special insect nest. There is a total gap of 200 points. We can only wait until tomorrow."
 Lu Chen looked at the glaring 0 above and thought helplessly.
 "Forget it, let's log in to the forum to see how they are doing!"
 Lu Chen had joined a local forum before and communicated with a group of people who built personal shelters.
 Fruit farmer: "A meteorite just fell nearby. Is everyone okay? Those who are still there, please make a bubble."
 Mechanic: "I'm far away and it's okay. Is everyone else okay?"
 Infrastructure maniac: "I'm a little closer, but I built it with high strength when I built it, so it's not a big problem."
 Little transparent: "Thank your ancestors for blessing me. I almost died. Now the shelter is almost destroyed. I have asked for help from the official. I will go to the official shelter later. See you all later. ”
 The forum user went offline not long after posting, probably to pack up his things
 Lu Chen replied in the forum:
 Struggling parasite: “I’m doing OK, just a little bit of loss, but I’ve dealt with it. "
 Lu Chen started chatting with a group of people in the forum.
 Suddenly, the infrastructure madman said: "I heard from the official that we are about to enter the Ice Age, and the global temperature will drop. Have you prepared heating equipment? Who has extra equipment? I have a lot of building materials here and can exchange with him."
 Everyone in the forum was silent after seeing the words of the infrastructure madman.
 Fruit farmer: "I don't have any here, I can also exchange. I have a lot of fruits here, and I can exchange with him with fruits."
 Mechanic: "Although I have heating equipment, I bought it before, which is only enough for my own family. Moreover, the heating equipment consumes a lot of electricity. You have to think about whether you have enough electricity."
 Lu Chen saw this and looked for it in the nano core, and saw such a heating equipment.
 ...
 Small heater
 Manufacturing requirements: 50 energy points, 10KG metal
 Power: 5 kilowatts
 Applicable space: 100㎡
 Description: Small heating Heating equipment, don't expect it to bring you much warmth, it can only guarantee that you won't freeze to death
 ... . . .
 Lu Chen was a little speechless after seeing the above introduction, but this is also a more practical device at this stage. Putting two at home can also ensure that the winter that lasts for decades is no longer cold
 Lu Chen saw this and replied on the forum, "I can make a simple heating device here, but the power is not high, and the maximum temperature can only guarantee 100 square meters, but the comfort level is not very good. Generally, it can be placed in the bedroom to ensure that it is at a comfortable temperature for a human body."
 Lu Chen just sent this sentence and received private messages from fruit farmers and infrastructure enthusiasts.
 Fruit farmers: "Rice worm, I can exchange fruit with you here. I will exchange 100 kilograms of fruit for one"
 Infrastructure enthusiasts: "Rice worm, I still have a lot of infrastructure materials and metal raw materials here. See how you can exchange them."
 Lu Chen looked at these private messages, thought about it, and replied:
 "Fruit farmer, I agree to your exchange terms, but you need to come here yourself. I don't have transportation, so I can't go to your place."
 "Infrastructure madman, I need 500KG of metal raw materials here, and I need you to transport them to trade. I can't go now."
 The infrastructure madman saw the reply and thought about it, and replied to Lu Chen: "I will give 1 ton of metal raw materials, I want to exchange for two units."
 The fruit farmer replied in a similar way and was also ready to exchange for two units.
 At this time, the mechanic found Lu Chen: "I want 3 units here. I have a second-hand pickup truck, which is 80% new. Can you take a look?"
 Lu Chen agreed immediately after seeing this. After all, it was still very inconvenient for him to have no transportation, so he agreed to the transaction.
 Lu Chen replied to them one by one in private messages: "I can only start manufacturing heating equipment tomorrow, and I can manufacture about 3 units a day, so fruit farmers, you come to pick it up tomorrow morning, infrastructure madman, you come to pick it up the day after tomorrow morning, and mechanics can only wait until the day after tomorrow."
 Looking at Lu Chen's reply, everyone was quite satisfied. After chatting for a few words, Lu Chen went offline.
 Lu Chen looked at the time. It was already six or seven in the evening. Lu Chen ate something, studied for a while, and then went to bed.
