Qin Shu studied life and death. When she received the admission notice from Tsinghua University, she was so excited that she tripped and fell into a book on immortality she was reading. In the book, she relied on her status as the legitimate daughter to snatch the spot of cultivating immortals. However, the heroine in the book, her concubine Qin Mian, still won the favor of the immortal cultivating elders because of her extraordinary talent. After that, the original body was regarded as a waste and her cultivation has not improved, but Qin Mian suddenly became a genius in the world of cultivating immortals, and brutally killed the original body during an experience. And Qin Shu happened to pass through the original body at the moment when she entered the sect. Knowing that the heroine would never let her go with her petty personality, Qin Shu decided to continue to roll up, work hard to become stronger, and change the outcome! So, Qin Shu practiced day and night, and was involved in life and death every day. At first, the fellow practitioners around her ridiculed her for being useless, but they soon became infected by Qin Shu, and they also became involved in the practice. As a result, Qin Shu went from being a useless person to becoming stronger and stronger, while Qin Mian went from being a recognized genius to becoming more and more useless. During this period, Qin Shu also met Xie Shiyuan, the demon king who was seriously injured in the back during the Thunder Tribulation and was forced to transform into his original form. While Xie Shiyuan complained about Qin Shu's involution, he secretly gave Qin Shu some advice, and also acted on his own and fell in love with the heroine. In the end, the two work together to break through the shackles, change the ending of the original book, and live a happy life.
