Ah Qiao's life plan is very simple: work as a chaperone in the leisurely Prince Yi's Mansion, get her monthly payment on time, have few things to do with her master, and be safe and sound until she leaves the house to get married. Her only hobby is playing chess. Colleagues were eating melon seeds and gossiping, and she was reviewing them in her mind. The little sisters were embroidering and tracing patterns, while she was fighting with herself. With this unique skill, she became the young prince's chess teacher, and occasionally she could play two games with the big boss, Prince Yi. The prince is a man of extraordinary grace and gentleness, and is the dream of all the ladies in the capital. A Qiao also thought her boss was handsome and kind-hearted, until one day, when she looked at the random game of chess played by the prince, she suddenly felt cold all over. On this chessboard, with the palace city as the belly and the imperial army as the eyes, the three parties' troops quietly surrounded and pressed forward step by step. It was clearly a road map for... Rebellion. But just now, she smiled and pointed out the "way to survive" for the prince. A Qiao: "..." Help! It seems that I accidentally participated in the rebellion! The way the boss looked at her changed from "This maid plays chess well" to "You know too much." In order to save her life, A Qiao began to live a daily life possessed by a drama spirit. The prince probed: "Ah Qiao, what do you think of my move?" Ah Qiao shook her head fiercely: "The prince is very thoughtful, but this servant is stupid and can't understand." The prince smiled: "It doesn't matter, I'll teach you." Ah Qiao screamed in her heart: No, no, no, I don't want to learn this! If you learn it, you will be silenced! This is a story about a low-level worker who accidentally discovered the shocking secret of his overbearing boss. In order to survive, he had to seek skin from a tiger, which ultimately turned the chess game upside down.
