The heavens are fickle, and life is downright rotten! A 45-year-old man born in the 1980s, a business tycoon in Winter City and a longtime member of the underworld, he leads the Tianshui Gang. The gang follows its leader's motto: never bully women or children, and go after unscrupulous businessmen. They're famous on the street for cleaning up the underworld, and the Tianshui Gang has always stood up for the weak and laid down its own rules.
A car accident leaves two people in danger. Yu Jingshen, leader of the Tianshui Gang, dies saving a young man! How strange: I open my eyes and I'm still alive, but why is my voice so childish? What the hell! I've transmigrated into that kid's body. I'm a high school student now!!!!! After getting a second chance at life, how am I still stuck taking the college entrance exams??? I've got a hundred days to work hard and get into a top-tier university? No way, I'm 45 years old. I can't manage that. I'll work hard for a hundred days and get into a third-tier university instead!
