When Zhuge Youyou was born, celestial omens appeared. Framed by others and accused of being born to bring misfortune to her parents, she was abandoned at the entrance of an orphanage by her superstitious grandmother. She was taken in by Zhuge Qing, the Sage of Chess and master of the Heavenly Chess Sect. Once every ten years, the World's Number One Chess Tournament is held, and every sect sends its greatest prodigies to compete. Because Youyou possesses the extraordinary Seven-Aperture Exquisite Heart, the Cunning Chess Sect schemes to send her down the mountain to participate. However, along the way, she becomes separated from her master, who suffers from dementia. A series of hilarious mishaps unfolds at the foot of the mountain. Ultimately, just as the World's Number One Chess Tournament begins, Youyou arrives and takes on seven top chess masters at once, using her mind to play seven games simultaneously and winning the championship.
