As the female teacher at the No. 1 Chess Academy in Jiangnan, Su Wanyi's life plan is very simple: teach chess, drink tea, occasionally win against a few blind fanatics, save enough money and return to the countryside to retire. Until that day, an edict invited her to the capital to become the youngest female chess master around the prince. Good news: The Tian family is rich, has no worries about food and clothing, and can play chess with the legendary top national players. Bad news: The prince is a sick man, and there is chaos in the court. What she teaches is not chess, but life. A game of chess determines the ownership of the three border cities. One step determines the honor and disgrace of court officials. She thought she was just a chess player, but later she discovered that she was already the most critical piece on the chessboard, and her advance and retreat were all abyss. The seemingly gentle and gentle Crown Prince always held her hand late at night and reviewed the chessboard: "Mr. Su, why do you want to give in on this move?" Su Wanyi said without raising an eyelid: "Leave a way for Your Highness to survive." He chuckled lightly, dropped a piece, and killed her dragon in an instant: "Nagu tells you that the real way to survive is to leave the opponent with no way to go." Su Wanyi: "..." Help, this job seems a bit dangerous! What about the promised paid pension? ! TAT goes from strategic moves on the board to deadly moves off the board. Su Wanyi discovered that in order to survive in this cannibal capital, she not only had to win the chess game, but also win the hearts of the people, and even... The entire world.
