The protagonist Li Fan is an ordinary programmer who lives a monotonous and boring life until he accidentally obtains a mysterious "Thousand-faced Book". This book gives him the ability to have multiple identities, allowing him to shuttle between different identities. Each identity is accompanied by different privileges and abilities, such as becoming a genius in the financial world, a superstar in the entertainment industry, or even the boss of the underworld. Li Fan used these identities to change his life, and at the same time encountered competition and challenges from all sides. As the plot progresses, Li Fan discovers that there is a huge conspiracy hidden behind the book, and he must find the truth, defeat the enemy, and ultimately achieve self-salvation among different identities.
