The next morning, Lu Chen got up and saw that the basic facilities of the shelter had been improved, and he was ready to further develop the shelter, after all, if there was no accident, he would have to survive here for a long time, and now that survival is not a problem, then he must let himself live comfortably and safely.

"Now I have ensured the needs of survival, but I still have to continue to build my own shelter, first of all, security, the house on the ground of my shelter should be surrounded by a fence, and then it can be connected to the power grid, and then add monitoring equipment to the roof, and then I have to prepare weapons and equipment when I go out, maybe I should first research out high-energy batteries, so that many portable devices have a place."

Then Lu Chen looked at the nano core, he had gathered more than 100 points of energy, and entered the battery data he found into the nano core, and found that if he wanted to achieve it, he needed 200 points of energy, and it was only the energy of deduction, he could only deduce the drawings, and he had to pay for energy if he made it.

Lu Chen took a look and found that there would be enough energy until four o'clock in the afternoon, so Lu Chen first took a shovel out of the shelter and began to dig a trench along the perimeter of his house, preparing to dig the trench first, and then build the wall when the energy and supplies were sufficient.

After Lu Chen dug the foundation, it was almost five o'clock in the afternoon, Lu Chen returned to the shelter, opened the nano core, consumed two hundred points of energy and began to deduce the high-energy battery, and then Lu Chen washed up and rested.

......

At nine o'clock in the morning on May 29th, Lu Chen woke up, looked at it, and found that the high-energy battery was about to be deduced for more than a day, and then Lu Chen washed up and prepared to take advantage of the fact that it was not too cold to go out to collect materials again, this time Lu Chen just drove the pickup truck out, without adding a car body, because this time he went out to search for some living materials, after all, items like some toothpaste, toothbrushes, towels and other items still need to be prepared more, although the use of nano cores can still be made, but there are ready-made why waste energy.

Lu Chen drove to the south of the city, the empty streets made people have a faint sense of fear, Lu Chen shook his head, and drove to the edge of a supermarket, only to see that this large supermarket was affected by meteorites, and the entrance had been buried, Lu Chen looked around and found that there was a parking lot, and then drove inside, because Lu Chen knew that generally this kind of large supermarket parking lot has entrances and exits, as well as unloading channels, but Lu Chen did not find the unloading channel for the time being, so he directly found the entrance of this parking lot.

Lu Chen got out of the car and entered the supermarket, and found that the supermarket was on the second and third floors, and the location on the first floor was some merchants selling clothes and jewelry.

After Lu Chen arrived on the second floor, he found that it was empty, and the shelves were empty, Lu Chen took a flashlight and walked around, and found that there was no gain, and then looked for it, found the supermarket warehouse, and found that there were two bags of rice, some condiments and edible oil, Lu Chen brought the shopping cart and put these things in, and then put the car on the second floor, ready to go to the third floor to see

Lu Chen came to the third floor and found that the third floor was to buy department stores and clothes, and it could be seen that a lot of things had been moved, but there were still a lot of leftover things, Lu Chen harvested a lot of things on the third floor, all of which were some daily necessities, but there were not many things, it is estimated that the group of people who came in front did not collect them all, and the specific pots and pans, towels, toothbrushes, toothpaste, underwear, underwear, underwear, underwear, toilet paper, etc., not only that, Lu Chen also saw a lot of aunt towels in the paper towel area that were not taken away, and it is estimated that there are more men who came out to search for supplies.

Lu Chen also found a warehouse on the edge of the third floor, which was the warehouse for these daily necessities, but the inside had been emptied, and it was estimated that it was to see that these packaged ones were easy to take away, so there was no need for the outside.

Then Lu Chen loaded all the collected materials into the car, and then drove to continue looking for where there were still supplies, after driving a few streets, Lu Chen saw a large shopping mall, Lu Chen took a look, and found that the shopping mall had collapsed, it was estimated that it was directly hit by a meteorite, and then Lu Chen drove around the street, trying his luck to see if there were any materials that could still be searched.

In the process of Lu Chen's search, there was still a bit of gain, he passed by a hardware store, found some wrenches, pistol drills, cutting machines and other portable processing equipment, and then Lu Chen also passed by a grain and oil store, and after entering, he found two bags of rice, three bags of flour, plus some cooking oil, seasonings, etc., and also found a home appliance shopping mall, where he found two microwave ovens, an oven, three rice cookers and other small electrical appliances, and even Lu Chen also saw a gas station, a place where liquefied gas tanks were filled, However, there is nothing in it, Lu Chen feels a pity in his heart, after all, the induction cooker is still a little lacking in firepower, and if you use gas, you can do it like some stir-frying.

After Lu Chen walked around the south of the city all morning, he found that the inside of his car body was almost full, so he drove back to unload the goods first, and then came back in the afternoon to have a look.

......

In the afternoon, Lu Chen continued to drive his small pickup truck on the street, Lu Chen drove and came to a street, Lu Chen looked around, and found that the whole street was full of car 4S shops, as well as shops selling heavy trucks, Lu Chen felt that he could go to the place where the truck was sold to see if there was any gain, and then Lu Chen drove to the truck shop, and found that there were only a few trucks left, no car body, and he had no key, he couldn't open the car door, Lu Chen was disappointed for a while:

"It seems that I am not very lucky, but I have come here, so let's go in and see if there is anything I can use."

Lu Chen entered the after-sales maintenance place and found that it was almost emptied, but it was estimated that it was in a hurry, and there were still many things that had not been moved, Lu Chen picked and chosen, found a lot of screws, and even found two barrels of diesel fuel in the warehouse, about 100 liters, Lu Chen was overjoyed

"It seems that you still have to go to these 4S stores to see, the oil in the gas station is estimated to have been pulled away by the official, and these 4S stores must prepare some oil for test drives, although not much, but this street is all these car sellers, and it is estimated that there will be a good harvest after searching."

Then Lu Chen began to go in one by one to look for it, and sure enough, he found a lot of oil, diesel and gasoline, a total of 300 liters of gasoline, 500 liters of diesel, and a lot of auto parts, and even Lu Chen found an engine in a warehouse, which was well packaged.

When Lu Chen had almost scavenged the area, it was almost night, so Lu Chen cleaned up and drove back to the shelter.

......

When Lu Chen put the materials he was searching for into the shelter, he washed up and finished eating, turned on the computer and found the mechanic.

Lu Chen: "Mechanic, are you here?" ”

Wang Xingyi: "Yes, what's the matter?" ”

Lu Chen: "Do you have more batteries over there, I need four or five here, I can exchange them for supplies,"

Wang Xingyi: "Lu Chen, I still have batteries here, they are all brand new, but I don't need the materials very much, do you have any oxygen production equipment over there, I feel very stuffy in the past two days, and I checked the Internet and found that it was a problem with the oxygen content of the air." ”

Lu Chen: "I can make you a small biological oxygen concentrator here, which should be able to meet your needs over there, but I want ten batteries." ”

Wang Xingyi: "Deal, you see when your side can be done, I'll go to your side to trade." ”

Lu Chen: "I don't need you to come over, there is the car you traded last time, I'll go to your side, by the way, I'll search for other supplies, today is the 29th, I'll go over on June 1st, tomorrow I need to make the oxygen concentrator at home." ”

Wang Xingyi: "Yes, then let's say so." ”

Then Lu Chen chatted with the mechanic, and the mechanic also gave Lu Chen the address of his shelter.

The reason why Lu Chen wants to exchange batteries is to wait for the high-energy battery to be manufactured, and directly transform the ordinary battery into a high-energy battery through the nano core, which saves time and will not cause too high energy consumption, after all, if the high-energy battery is researched, he can't make it without the corresponding equipment, and he can get it out by himself, Lu Chen said that he is not Iron Man, nor Steve, before that, he was an ordinary person, Although he has improved his brain and body because he binds the nano core, he is still an ordinary person, and he is not as strong as Captain America in terms of physique, and he is not as high as Iron Man in terms of intelligence, so it is the most correct choice to do what he can do, and why not open it if there is a plug-in, isn't it fragrant to directly use the nano core to transform him,

Finally, Lu Chen said that when Lao Tzu researched artificial intelligence, with the almost plug-in ability of the nano core, he would take off directly, and the most important thing now is stability, just like this battery, if you want to manufacture it yourself, then get the battery factory, transform the equipment of the battery factory, and then put in raw materials, and then produce and manufacture, and don't do so much yourself, ten yuan is enough, so Lu Chen will ask the mechanic to store the battery.

Then Lu Chen continued his learning journey after going offline, after all, before the energy was insufficient, the technology had to climb by itself

......

On the other hand, Wang Xingyi happily told his wife about the transaction with Lu Chen after going offline, and the little couple was also very grateful to Lu Chen, after all, everyone is staying in the shelter now, it can be said that the battery can be found in any repair shop on the street, Lu Chen can find it by himself, but Lu Chen didn't, but made a deal with himself, you must know that the oxygen generator can only be exchanged here by Lu Chen for himself, but the battery is not owned by himself, so Wang Xingyi's family is still very grateful to Lu Chen.

......

On the other side, Lu Chen saw that the time was not too early and was ready to sleep, and then before going to bed, he habitually thought about what he should do tomorrow.

"Tomorrow's energy points should be enough, you can make a biological oxygen concentrator first, and then lay a good foundation on the periphery, so that the high-energy battery can also be studied at night, and when you go to the mechanic to do the transaction the day after tomorrow, you can start manufacturing protective clothing, and you can directly add the power exoskeleton together, so that you can wear it directly when you go out, whether it is searching for materials or going out to trade."

Then Lu Chen washed up and went to sleep.
