Stock up the refrigerator and read about natural disasters" Zilmu

　　Whether it’s floods or extreme cold and heat, water is tough.
　　Needless to say, floods can contaminate water resources with large amounts of bacteria. In the last days of extreme cold, the world is frozen. You have to work hard to cut the ice, but it will still pollute the water when it is thawed.
　　It was extremely hot and everyone was left to dry out.
　　She doesn't have much space now, so hoarding a lot of water resources is a fantasy. The best way is to buy water purification equipment and water storage containers to collect rainwater at the end of the flood.
　　The price of water purification tablets is still acceptable, so you need to buy them in large quantities.
　　This thing will definitely be more expensive than gold in the last days. The more you buy, the better.
　　You also have to buy a water purifier. Considering that electrical appliances wear out a lot in an apocalyptic environment, you have to buy at least twenty units, along with matching filters.
　　Fortunately, water tanks are not expensive.
　　Ruan Ning compared the left and right, gritted her teeth and ordered one water tower with a capacity of 100 tons and two water towers with a capacity of 20 tons.
　　After paying the money, her heart was bleeding, but this thing was so useful.
　　As soon as it arrives, she can fill it with water first, so she doesn't have to filter it again.
　　This alone is not enough, Ruan Ning also bought a lot of foldable water storage tanks, which can be unfolded to store water when the space becomes larger in the future. ‖Si‖Tu‖Net‖
　　In this store selling water towers, Ruan Ning discovered another good thing.
　　The indoor soilless cultivation planter costs about 5,000. It has a built-in lighting function, simulates sunlight, and a water circulation system. It is
　　very exciting, although it has a source of vegetables.
　　Ruan Ning was in a dilemma and hesitated for a long time, but finally gritted her teeth and placed an order for two units.
　　Compared with a piece of cold-proof clothing that costs more than 4,000, this price is really not expensive, and it will be very useful in the future.
　　If it weren't for poverty and space constraints, Ruan Ning would buy 10,000 units!
　　You must know that before the end of the flood, the sun will erupt with a super flare. At that time, the global power system will be destroyed, and various electrical equipment will also be devastated.
　　During her free time while taking a taxi, Ruan Ning took the time to read the beginning of the novel. According to the description in it, most people are not prepared when a solar flare comes. The damage rate of mobile phones is 100%, the damage rate of household appliances that are powered on is 100%, and even Factories large and small across the country and around the world are unable to operate.
　　The electronic components used in the car will be scrapped directly, even if it is not on the road, because the car has its own battery, which will also be impacted.
　　When the time comes, it will be extremely difficult to change accessories.
　　This super flare has set human technology back hundreds of years.
　　Immediately after the flood apocalypse came, it was difficult for human beings to maintain basic survival, let alone develop science and technology.
　　Only the country still has a little bit of spare power, and after the end of the flood, it invested in soilless cultivation and other technologies, struggling to maintain the remaining glory of mankind.
　　However, if the electrical appliances are placed in her space, the equipment will not be damaged.
　　It's a pity that her space is only one hundred cubic meters, which is of some use to an individual, but to the entire country, the entire Blue Star is a drop in the bucket.
　　As for making apocalyptic remarks in a big way online?
　　The most likely result will be nothing, and you will be called a fool by two or three netizens. If you are accused of spreading rumors, you will be screwed.
　　Ruan Ning didn't dare to bet that her parents would come to this world. If something went wrong and she didn't stock up on enough supplies or died, what would her parents do?
　　Night comes quietly.
　　Ruan Ning cleared the space in the external refrigerator, took out beef stew and cabbage, and finished her dinner in a scruffy and rich way.
　　In the evening, she continued to expand her shopping list.
　　In addition to the supplies purchased earlier, Ruan Ning also purchased medicines and medical equipment from different stores. You must know that in addition to cold medicine, antipyretics and vitamins to refresh, she had to buy everything else.
