Wang Xiaoliang, an ordinary college student who is about to graduate, is confused in life and has achieved nothing. Stimulated by his roommate's jumping off the building, he accidentally obtained a seemingly absurd "Book of Destiny". Following the seemingly ordinary "life-changing techniques" in the book, he began to clean diligently, keep a regular schedule, and say good things, and his life really began to undergo earth-shaking changes. Not only did he successfully start a business, he also got together with Wei Zijin, the school beauty he had a crush on for four years. However, when good luck came one after another, he gradually discovered that there seemed to be a deeper meaning behind the guidance in the "Book of Destiny", and a huge test about changing his destiny was quietly unfolding.
