Zhao Xue and several people focused on the harm of solar storms, which are divided into three aspects, the first is to affect the safety of satellites, which may cause logic errors in microelectronic devices, cause program confusion, and in serious cases, may cause short circuits and breakdowns inside the devices. The second is to affect communication and navigation, as long as a solar storm occurs, it will affect human radio communications, causing the interruption of satellite communication links and so on. The third is to affect ground technology, the emergence of solar storms will cause geomagnetic storms, and the drastic changes in the earth's magnetic field will induce geomagnetically induced currents on the earth's surface, and this additional current will damage or burn the transformers in the power grid, causing power outages. This has the greatest impact on human life.

After that, Xu Haoran found a video from his mobile phone, about the disaster that mankind will face after the solar storm comes, a total of fifteen minutes, and several people watched it very seriously.

Zhao Xue also took out her small notebook and listed the materials that needed to be prepared for the disaster that appeared in the video while watching.

After the video was played, several people breathed a sigh of relief.

"I'm only twenty-two, I really don't know how I lived forty years ago when there was no electricity and no running water, and I still have food stamps, I have never seen it." Xu Haoran shook his head and sighed.

"It's not just you, we haven't seen each other. Okay, don't say it's useless, I don't know when the disaster will come, we must hurry up and stock up as much as possible, I'll talk about what I think of first, and you will replenish it in a while. Zhao Xue picked up her notebook and began to speak, "The main disaster of the solar storm for the people is the power outage, no electricity is terrible, no scientific and technological products can be used, and the preparations we have to make should also focus on this point."

First of all, you can't use your phone to buy things without electricity, so you have to prepare as much cash as possible. ”

"Do you have money to prepare? When the time comes, there will be no electricity and no water, and it won't take long to mess up, is it still useful to prepare money, I guess whoever has a hard fist will have the final say. Xu Haoran reminded that the monster world he and Sister Zhao went to before was like this, at the beginning he was stupid to take points to exchange money for materials, but within a few days he had to run out to live on the street, and the materials prepared in advance were useless and wasted.

"The chaos is definitely going to be chaotic for a while, but I just learned about the situation in this country, if what is said on the Internet is true, the country will not let this chaos last too long, even if it can't be taken into account, these residential communities in the city are also the first place for the army to order." Lee disagrees, after all, the country's government is people-oriented.

Zhao Xue nodded approvingly, that's for sure, disaster relief and rescue soldiers have always rushed to the front line, without exception.

"It must be so, the military of our country is this." She gave a proud thumbs up, "So, before the military takes over the city, it is very necessary to have some cash and weapons." ”

"When I came over, I grabbed a storage backpack, and there was only one cubic meter for 10,000 points, and I brought some of the important ones with me." Zhao Xue said, opened her backpack, and took out a large pile of cash from it.

"Wow, where did all this come from?" Fu Hanru happily watched her take out a stack of stacks, and at a glance, she knew that she was also a money worshipper, and her eyes lit up when she saw the money.

"I bought it in the last copy." Zhao Xue calmly pushed the money on the coffee table, very energetic to spend a lot of money, and pressed a handful of li001 on top of the money.

Xu Haoran grabbed the gun in annoyance, "You said I was stupid, why didn't you think to bring my gun." "He also had the same gun in the last copy, but after the copy was released, he put the gun in the warehouse, and he couldn't open it when he came to the warehouse here, and the gun couldn't be taken out at all.

Li Weixuan took out the storage bag that he had never left with a smug face, and then learned from Zhao Xue and took out the materials he stored in the bag, mainly for display, proud display.

"Wow, Brother Li, you are good enough, and there are really a lot of weapons in store." Immediately, Xu Haoran was dazzled by the various bows and crossbows and cold weapons that Li Weixuan took out.

"It's okay, my main storage is weapons, and I don't have Xiao Zhao's heart." Li Weixuan was modest.

After the two of them posed together for a while, they finally got to the point again.

"In addition to weapons, we also need to store some daily necessities, such as lighting tools and candles that do not use electricity."

"We still have to buy some fuel, we have to use it for cooking and boiling water, we can't do without this for the time being, it's unrealistic to chop wood or something."

"And tools, axes and saws, in case you need to use them in the future, you won't be blind."

"It's September, and although it's the south here, it's not too cold in winter, but I also need to buy a few more quilts in case of emergency."

"You have to have enough medicines, cold medicines, diarrhea medicines, antibiotics, etc., and in the future, there will be no electricity, and the medicine will not be produced, so you need to be prepared."

Zhao Xuelala muttered everything she thought of, and then asked everyone to add.

"Tents and sleeping bags have to be bought, and in a month we will most likely have to go out of the city, and it is slightly better to have tents outside." Xu Haoran said.

"I also have to buy water purification tablets, there is no tap water, there must be some water to drink in the future, prepare some water purification tablets, save diarrhea and parasites." Li Weixuan added.

"And buy some underwear and toilet paper or something, you can't wash them if you don't have water." Fu Hanru also filled in two things, she is a girl, and her focus is different.

"There must be transportation, and if you can't turn on electricity, you can only replace it with human manpower."

"Lighter ......"

Zhao Xue wrote down all the things that everyone added, and after making sure that there was nothing to add, she began to assign work.

"I'll take care of the rice, flour, grain, oil and water, my family runs a small supermarket, and I'll call the wholesaler to send me some more goods in a while. In addition to these, my family's money also has to find a way to get out more, that is, all the money saved by my family is the death period, and the cash withdrawn on the day is estimated to not exceed 50,000," Zhao Xue calculated, there should be two passbooks at home, one is the passbook that her parents have saved for many years, and the other is the 160,000 she won in the lottery some time ago, "I should be able to take out nearly 100,000 more, in this way, it adds up to 430,000, which should be enough in the early stage." ”

"Brother Li, you go buy tools and outdoor products in a while." Zhao Xue gave him a list and asked him to buy it, and then handed him a credit card, "You take this, you can swipe it directly when you buy something, and the password is 456823."

Li Weixuan took the credit card, raised his eyebrows and asked, "Yours?" ”

"My dad, they did both of them for what kind of activities, and they haven't used it, but the overdraft limit should be 20,000, and you will use your mobile phone to log in to my payment software for a while, and when the credit card is swiped or can't be used, you will use your mobile phone to pay." Zhao Xue just turned out the family's savings and all the cards, and there was no electricity in the future, so if she didn't take advantage of the two days to swipe hard, she would never have a chance again.
