CZ City, eleven o'clock in the middle of the night, Lu Chen's home

"Today is May 18th, since scientists detected the meteorite and almost a year has passed, three days ago the astronauts landed on the meteorite for blasting, but miscalculated the hardness of the meteorite, the number of nuclear warheads carried is insufficient, only the internal structure of the meteorite can be destroyed, but the meteorite can not be disintegrated, but the remaining time is not enough to send astronauts to the scene to blast again, the United Nations decided to evacuate the people into shelters within three days, and launched the Shattered Star program, planning to launch a nuclear bomb to destroy the meteorite in the atmosphere, Although it will cause a large amount of radiation to be produced around the world, the success of the plan will ensure that the earth's civilization will survive, and good luck to us. ”

Lu Chen looked at the content on the TV and thought: "Fortunately, I built the shelter in advance, and I can go to the shelter to avoid the impact when the time comes, but if it is not broken, or it is not completely broken, it is estimated that it will be difficult to escape the fate of GG by hiding in the shelter, and it seems that I can only resign myself to fate."

Suddenly, a light lit up outside the window, and before Lu Chen could react, he smashed directly at Lu Chen, and Lu Chen immediately fell to the ground, unconscious.

At 11:30 in the middle of the night, I saw Lu Chen lying on the ground in the room, with a hole in his clothes, and a wound on his chest could be seen at the crack that was healing rapidly, and the scene was very weird.

Suddenly, Lu Chen opened his eyes, took a deep breath, sat up suddenly, checked his body, and found that there was a big hole on the clothes on his chest, but he touched his chest and found that it was intact.

Suddenly, a burst of information came to my mind, and I realized that I had lost my luck.

It turned out that what hit Lu Chen was the nano core, a scientific and technological product of advanced civilization, the nano core can devour matter to produce nano worm swarm, and the nano worm swarm can analyze items and copy them, and at the same time, it can also strengthen human body functions and strengthen the speed of brain calculation.

The nanocore that hit Lu Chen has already mutated, and at the same time as hitting Lu Chen, it has bound DNA information to recognize the owner, but because it hit Lu Chen's heart, Lu Chen's life was in danger, and the nanocore detected that the host was in danger of life, repaired Lu Chen's heart and mutated at the same time, which can condense a nano storage device and import the drawing, and then after absorbing the storage device, it can be manufactured according to the drawing.

"I feel that my ancestral grave is smoking, this is the legendary catastrophe that will not die, there will be a blessing in the future, now you don't have to worry about the survival of the back, you can eat and drink spicy food in the future, and although some organic substances cannot be produced, but I can make equipment to change it, hehe"

Lu Chen is also big-hearted, he has just experienced life and death, but he is like a nobody.

"There are still three days left from tomorrow to the Shattered Star Project, and I was going to have three days to check and fill in the gaps to see if there are any neglected equipment and facilities that have not been purchased, but now the plan can be modified and modified,"

Lu Chen was ready to revise the original plan and calculated the materials that still needed to be collected

"At present, a part of the sand, gravel, cement and steel bars have been collected, and I was going to buy another batch, but now I can save it, and I can use alloy materials for later expansion, but I need to increase the purchase plan of special alloys, and I can buy some samples for each one, but now it is estimated that I can't buy it at this time, you can swallow some conventional items first, and you can also copy all the equipment in the shelter later, and then it can be repaired and replaced in case it breaks."

Lu Chen then thought

"Since some supplies and equipment can be saved, then you can add some other things, which can make the shelter conditions better, think about what equipment can be added"

Lu Chen suddenly thought that many devices could be canceled after having a nano core, after all, you can also build it yourself by downloading drawings and materials on the Internet, there is no need to waste your own funds, although it is said that prices have increased sharply now, but after all, the system of the Dragon Kingdom ensures that the country is not in chaos,

Unlike abroad, where there have been large-scale riots at this time, crime incidents have risen sharply, such as some robberies, shootings and other incidents emerge one after another.

However, in China, because the credibility of the government is very high, so the people believe that the government will lead everyone out of the predicament, coupled with the government's severe crackdown on illegal crimes and price hikes, except for the rise in prices, the lives of residents have not been greatly disturbed, and production activities have also maintained normal operation, providing a strong backing for the construction of official shelters.

"First of all, the equipment already in the shelter can be replaced with a better one, my generator is just an ordinary diesel generator, and the battery pack can also be replaced with more efficient power storage equipment, and I will check what good equipment is available on the Internet, after all, many equipment is electricity, first of all, we must ensure the power supply,"

Lu Chen's first thought was that the energy supply must be stable, otherwise many equipment would not be used.

"The second is the water source system, after the energy is guaranteed, you have to ensure the necessary water and food for survival, now there is a water tank in the shelter, which is designed to store 15 tons of water, plus a rudimentary water collection device, but it can only collect and filter rainwater on rainy days, this also needs to be renovated,"

Lu Chen checked the information on the Internet

"The place where I am located is in the south, and there are many underground water systems, so you can use the nanocore to build a well below, and then add a water pump to pump it up to ensure daily drinking water,"

"That's right! It seems that I have to take into account that if the groundwater is pumped too much, it will cause it to collapse, and I have to reinforce it with nanoworms under the shelter, and it doesn't matter if it collapses elsewhere, I can't collapse down here."

Lu Chen suddenly thought that he had seen others say that using too much groundwater would cause the ground to collapse, although he didn't know if it was true, but just in case, it would be better to strengthen it, anyway, it wouldn't cost much material.

"Water and energy are solved, below is food, the materials I store are about enough for me to use for a year, they are some easy to store food, but fresh vegetables and fruits are not to think about for the time being, then the plant cultivation room also needs to be improved, according to the previous design, the cultivated plants are only enough to extend my survival time for another half a year, but now I can expand the area of the cultivation room."

Lu Chen suddenly thought that if hybrid rice breeds the next generation, there will be trait separation, resulting in a decrease in yield, so it is necessary to prepare more seeds, and vegetable seeds must also be prepared, after all, many breeding generations are not good now.

"Now the yield of rice per mu is about 800 kilograms, and the grain consumed by normal adults a year is about four or five hundred catties of rice, so I only need to open up half an acre of space, and rice can be planted hydroponically, and more space can be saved, and vegetables are grown in hydroponics in the original place."

"And I can also close the cultivation room and adjust the internal temperature and humidity to ensure that there are two crops a year, so that I can use the limited space to get more food, but meat is not easy to obtain, and I can only ensure the daily consumption of the body by eating a lot of rice and vegetables."

Lu Chen thought that the meat was not easy to get later, so he could only ensure that he was not hungry first, and then consider adding food and clothing.

Lu Chen recorded the areas he needed to improve in his notebook, and now that water, food, and energy have all thought of ways to improve, the next is safety.
