Amid the turmoil of the mid-Tang Dynasty, Gu Shiyan—the realm's greatest Go master—is gravely wounded and rescued by the enigmatic monk Kibi no Makibi at the Temple of Buddha's Cliff. During his recovery, he encounters haunting mysteries: a white-robed maiden whose ethereal poetry echoes through the plum groves yet vanishes like mist, and a legendary Go set (Qiuyu Qipan) rumored to grant invincibility. To find his lost love, Wu Jie Shanluo, Gu ventures into the labyrinthine capital of Chang'an, where Hu and Han factions clash in shadows. As the art of Go collides with Zen and treachery, he must master the board to survive a deadly game of power and love.
