Library

My name is Han Bing. At that time, I was 25 years old. It was just one year after I graduated from college. Because I offended my boss, I lost my job and broke up with my girlfriend. So, I returned to my hometown, City A, in anger. After two months of confusion, I finally found a job as an assistant in the library through my connections. At the beginning, I was unwilling to give in. After half a year, I finally calmed down and started reading a lot of books in the reading room every day, and I gained a lot. Just when I thought that the rest of my life would pass by in such a blur, suddenly one day, I accidentally touched an old book in the corner of the library. A secret door that had never appeared before gently opened, and I saw a dark staircase leading to the underground. As I climbed down, it was pitch black. , I couldn't see my fingers, I walked carefully all the way, it felt like the time was so long, just when I thought I was reaching the end, I suddenly tripped, and then it seemed like I fell into a bottomless abyss. I screamed in fear, but found myself opening my eyes beside the table in the reading room. Looking at the familiar environment, I finally woke up. It turned out to be a nightmare, but for some reason, my life trajectory has completely changed since then. Some people say that I have selective amnesia, others say that I have bipolar disorder, and some even say that I have entered a parallel universe...
