It begins with rhyme and ends with darkness. This is the beginning of darkness and the ending. Countless betrayals, humiliations and other past experiences are all presented here. The story of An, the most miserable overlord of Mao Tu, who has been wandering and full of pessimism throughout his life, will be recorded in words. The initial ignorance, the dream of entering the world, the continuous research on his hobbies, the backstabbing of his friends, Mao Tu's step by step advancement, and the memories of his final blackening are all the motivation to support his progress. (There is no heroine in this book. Master An is devoted to his goal and has no time to talk about it.)
