After Lu Chen solved the basic survival, he began to think about his own safety, although there is government control, resulting in the current environment is very safe, but the heart of harming people is indispensable, the heart of preventing people is indispensable, and everything is considered in the worst case. "First of all, there is a structural problem, my shelter is an ordinary reinforced concrete structure, so I need to replace the internal structural reinforcement, and then I have to buy high-grade anti-radiation paint, replace the low-quality paint inside the shelter, and the ventilation system must also be modified to ensure that no harmful gases are inhaled, and the water source is ready to use groundwater, and there is no problem with temporary safety."

Lu Chen thought about it again:

"There is also a gate to the shelter that needs to be replaced with an alloy gate, and one gate is not very safe, you can add another gate, so that you can install defensive weapons between the two gates, and you can also give yourself time to reflect,"

"In addition, a garage can be built on the ground floor, and a lifting platform can be installed in the garage, so that large or heavy materials can be transported down"

It was already one o'clock in the morning, but Lu Chen was not sleepy at all now, and his interest was completely aroused.

"In this case, the ground needs to be equipped with protective equipment, and a lifting platform must be built, and preferably above the warehouse, a hydraulic freight trolley is needed to facilitate the transportation of goods."

Lu Chen continued:

"There are also internal and external monitoring facilities that have to be transformed, and the outside is connected by wireless and wired, so as to prevent others from cutting the transmission line and not seeing the outside, and the internal connection can be connected with a network cable,"

"The other two security doors can only be installed with automatic crossbows, although they can't be bought, but one can be made with nano cores, this is added later, now let's get the survival done first, after all, it's not so messy at the beginning, and you can see if you can get a gun later, or you can make one yourself according to the information on the Internet,"

Suddenly, Lu Chen thought:

"If you need to build a gun, it is estimated that it is useless to rely on my plastic 3D printer alone, and it is a bit useless to build it with a nano core, you can copy a small machining center, and then expand the workshop, but in this case, you have to equip the workshop with a transformer, think far"

Lu Chen smiled bitterly and stopped himself and continued to diverge his thinking.

Lu Chen then thought that an ordinary 3D printer would definitely not work now, so he checked the information on the Internet and found that there was already a domestic metal 3D printer on the market, which could be used excessively.

"Just with this printer you can transition to use first, although the 3D printer is good, but the current technology still has a lot of shortcomings, can be used with the processing center"

"Now that there are plans for survival and safety, let's add the rest later, these plans will be used as a backup first, after all, I don't know if the meteorite can be broken, if it is broken, then there is no need to be so troublesome."

After Lu Chen finished writing these, he then thought:

"There are still some materials that need to be purchased again, and they can only be given up because of limited funds before, but now with nano cores, you can save a lot, so that you can add several equipment and materials to the re-examination rate."

Lu Chen then wrote in the notebook:

"We also need to add some high-strength alloys, as well as a large number of basic materials, after all, even if we know the formula of special alloys, without basic materials, there is no way to manufacture nanocores."

Lu Chen thought about it and found that his current ability could only be taken into account for the time being, and the rest could only be checked and filled in later.

"Forget it! It's not too early, and I'm a little sleepy, so let's go to bed first, and start implementing the plan tomorrow. ”

It wasn't until now that Lu Chen's excitement to get the golden finger slowly subsided, and the corresponding sleepiness began to strike, and he finally fell asleep

Nothing to say all night........................

.............................

The next day, Lu Chen woke up from the alarm again, and the first thing he did when he woke up was to make sure that the nanocore was not there, and after finding that the information was true, he breathed a sigh of relief.

"It's good that it's not a dream." Lu Chen patted his chest.

"Let's go out and buy materials today, and you can go to which equipment manufacturers to see if you can go in and secretly copy some equipment, hehe"

Lu Chen separated a wind from the nanocore and made a hard disk, plugged it into the computer desk and began to download the materials, and then prepared to go out and start buying materials, suddenly Lu Chen thought of something

"Coupled with the national mineral distribution map, in case there are no materials or transactions in the future, then you can also go to mining"

Then Lu Chen went out and started to get busy

.........................................

First of all, Lu Chen first went to the steel factory, ordered some metal raw materials, and then found a local 3D printer manufacturer to buy a printer, and then went to the vegetable market to buy some vegetable seeds and hybrid rice seeds.

"Since you buy rice, let's buy some wheat seeds, and since you're going to plant these, you have to buy a threshing machine, hey! It's all money."

Lu Chen found that he was going to keep some money for his family, but how did he feel that he was spending more and more

"It's really a bastard, it's gone in a blink of an eye," Lu Chen looked at his balance and smiled bitterly.

"Forget it, when the things arrive, let's transform the inside of the shelter first, at least the power system must be transformed, and the rest can be put back" Lu Chen considered that the nano core needs energy, and while the power supply is not cut off now, the power system inside the shelter will be transformed first, so that in case the situation is not good, the external power supply can be interrupted to ensure that the power supply of his shelter is normal. ”

Lu Chen then thought that he could go and see if there was a geothermal generator for sale, and checked it on the Internet, and his spare money could still afford to buy a small geothermal generator, but the battery had no way for the time being.

"However, after the geothermal generator, the battery bank is also a backup power source, and you can save a fortune."

Lu Chen was quite happy when he thought of this,

Later, Lu Chen checked the Internet and found that although there are geothermal generators in China, even the most miniature of his own shelter can't be placed, so he has no choice but to download the information first, and then go back to make it with nanocores.

Thinking of this, Lu Chen decided to just buy these things first.

"Anyway, there is no money now, many things can only be used later, and there may not be any money in the future, I can barter for things, with such an artifact, I can't starve to death."

Then Lu Chen took a taxi back home and looked at the information that had been downloaded.

"Everything is ready now, just wait for the results in three days," then Lu Chen thought again:

"Now I'm just waiting for things to arrive.,It's okay to start learning for the time being.,Anyway,It's not wrong to learn more knowledge.,Now after the transformation of the nanocore.,My body and brain have been developed.,Although I don't have the ability to remember.,But it's not much worse.,What you master is your own"

Lu Chen thought that it would not be a problem to wait, so he began to browse the materials downloaded into the nano core, and began to learn, at least in case there was a problem with the nano core that day, there was a means of self-protection.
