Liang Xiao grew up in an orphanage. He was an excellent student and easily got into one of the top universities in South China's province. At a school gala, he confessed his feelings to Shen Mei, the class beauty, only to discover that she already had a boyfriend. It turned out that after learning Liang Xiao was pursuing Shen Mei, her boyfriend had told her to deliberately get close to him, then humiliate him in front of the whole school. Liang Xiao had been insecure since childhood, and couldn't bear the shame. He ran to an abandoned building and leaped off. As he fell through the air, a voice suddenly rang in his mind: "Ding-dong! The strongest System has been bound to the Host, you lazy fish!" Watch him turn his life around!
