This is a full-length realistic novel that is deeply integrated into the science of black and white, the game of human nature, and workplace promotion. It focuses on the marketing department of a large Internet company, and fights all the way from the grassroots specialist to the position of director. It thoroughly describes the complete set of survival rules for promotion, siding with the team, dumping the blame, grabbing credit, checks and balances, layout, and counterattack. The rhythm is tight, the conflict is intensive, the whole process is high-energy, and the whole process is full of darkness.
