In recent years, there have been frequent natural disasters on the earth, frequent earthquakes, droughts in the north, floods in the south, and rare super typhoons in coastal areas. It made people panic, and some wondered if the end of the world prophesied by the Maya was already happening in another form. At this time, Li Mo, an ordinary university student, like everyone, lives a carefree college life every day.

"Xiaomo, have you heard, there was a big explosion in a dangerous goods factory in Tianjin, it is said that more than 100 people have died, and a deep pit created by the explosion can even be photographed by satellites, so terrifying." Li Mo's tablemate and roommate Xie Yuan said in surprise while watching the news on his mobile phone. "Well, I heard that the fire has not been extinguished yet, and many firefighters have sacrificed themselves. Let's hurry to class, or we'll be late. Li Mo looked at Xin, his eyes darkened, and said. Silently picked up the books needed for class, ready to go to class, the afternoon is the ideological and political class, is the big class of the grade, the class is an old man in his fifties, the class is read according to the textbook, it is very boring, people listen to it, they want to sleep, so many students like to skip class, but this old man is very treacherous, it seems that there are few people in the class, that is, the name is on it, write it down, if there is more absenteeism, then you are finished, no matter how good you are in the exam, you will be disappointed this year. Then just wait for next year's exam. Li Mo is a member of the study committee of the class, usually to inform the classmates of the class of the course arrangement, collect homework, but also quite idle, today's class, sure enough, the teacher saw that there were fewer people, and named again, so the teacher recorded it in the book, and more than ten people in the class died gloriously. Li Mo actually doesn't like this class very much, but because she is a member of the study committee, and she needs the scholarship money, she can't hang up a subject, so she can only stick to it. Li Mo's family is not rich, her parents are farmers, and they rely on farming to support their families every year, she originally had no money to study in college, but Li Mo went to the bank to take out a loan, and she could pay it off within a year after graduation, without interest, her plan was to take out a loan to pay for tuition, and then rely on scholarships for living expenses. Li Mo has a secret in her heart, she likes a boy named Zhong Peng in her class, Zhong Peng is the kind of tall and thin type, three-dimensional facial features, very gentle. She usually likes to wear white shirts, and every time she sees him, her heartbeat suddenly accelerates, and she often thinks that it would be nice if he liked her. But this is just thinking about it, because she heard two days ago that Zhong Peng had confessed to another girl in the class, that girl's name was Yu Wan, she was from the same city as her, and she was very beautiful, when she heard Li Wan tell her, she could only bury the secret again, and silently shed tears in her heart. That night, Li Mo hid in the quilt and wept silently, not letting anyone know, and the next day, his eyes were also red. Life goes on as usual, Li Mo is an optimistic person, if no one loves himself, then he will love himself more, in a few days it will be his birthday, on his 20th birthday, he gave himself a gift, this day she saw a bracelet when she visited a jewelry store, and immediately attracted her attention, this bracelet is green, more than a dozen beads emit a soft luster, Li Mo likes it very much, but after turning around, I found that this bracelet has a bead in the middle of the bead There is a sesame big black dot in the middle, frowned. "Boss, how did you sell this bracelet?" "Little girl, this bracelet is 100 yuan, it's very beautiful, buy it if you like it." The boss said as he put down the bracelet. "Why is it so expensive, boss, there is a black spot in this bracelet, is it okay to have less?" "Oh, little girl, it can't be missing, this bracelet is sold so little because of the black spots" You look at the similar ones next to this, it's not at this price." Li Mo looked at the one next to him, it was indeed a lot more expensive, and after looking at it, he really liked it, who was more expensive, but today was his birthday, so he gritted his teeth and bought it. After giving the money to the boss, I put the bracelet directly on, which was just right, and I felt a lot more comfortable. I went to buy some other daily necessities and went back to the dormitory. "Xiaomo, have you heard, Li Qing and Zhong Peng are already together now, today I saw them at the school gate and just came back from a date, holding hands together, not to mention how sweet it is." Xie Yuan saw Li Mo coming back and gossiped. "It's progressing so fast," Li Mo said bitterly. Silently put things away, went to the shower and went to bed. Li Mo was lying on the bed, looking at the bracelet he had just bought today, his hand stroked it gently, and smiled, for Zhong Peng, he really let go now. I let out a long sigh, closed my eyes, went to sleep, and had to wake up early for class tomorrow. What Li Mo didn't know was that in a place they couldn't see, a disaster was quietly spreading. When I got up the next day, there was a lot of news on the Internet that many citizens in City B suddenly fainted and were sent to the hospital, and the hospital was helpless, it is said to be a flu virus, infected through the air, infected people, the whole body is hot, lethargy, and now the hospital is overcrowded, and many can only recuperate at home because there are no beds. Many schools over there have also closed for the holidays because of this. The place where Li Mo lives has also slowly begun to spread. Li Mo just finished reading the news, looked at Xie Yuan who was playing with his mobile phone on the bed, and said worriedly, "Yuanyuan, let's go to the supermarket to buy something and save it, at this time, the flu will rise, and you can cook rice at that time." Even if it doesn't rise, we can keep it and eat it slowly, don't go out, otherwise we will be in trouble if we are infected. Li Mo said worriedly. "Okay, I don't really want to go out during this time, let's buy more." Li Mo and Xie Yuan took the oversized shopping bag and went to the supermarket opposite to buy it, Li Mo took a lot of bread with a long shelf life, and a lot of noodles, the noodles are cheap and easy to cook. I also bought some chocolates, and when I was hungry at night, I could lie on the bed and eat, Xie Yuan also bought a lot of things, and there were a lot of snacks, accounting for half a bag, and the small cart for two people was full, so I went to check out, and they decided to buy it back first, and if it wasn't enough, they would come back for a second trip. The two of them carried heavy bags and walked back from the supermarket with difficulty, and they were relatively close to the place where they lived, otherwise they couldn't go back at all, and when they arrived at the dormitory, they were so tired that they couldn't move in bed. Li Mo looked at the things he bought, feeling panicked in his heart, as if something was going to happen, he picked up his mobile phone: "Hey, Dad, there is a flu during this time, it is full of seriousness, it may soon spread to us, you buy more things at home, try not to go out, prices should rise today, buy more rice and save it." "Well, I know, I also watch the news, so be careful over there." After making the call, Li Moyou went out to buy some things before he felt better.
