In the twenty-sixth year of the Republic of China, the war of resistance broke out, and the southwest was in chaos. Chen Jiu, a prodigy in the chess world of eastern Guizhou, was plotted by the warlord Vulture. His right hand was broken and he fled to the river. He escaped to Miao territory after a narrow escape and was rescued by the chess saint Aman with a secret poison. He accidentally awakened the legendary ghost hand chess bone and learned the secret skills of the chess master of the Southern Ming Dynasty.
In order to avoid pursuit and protect the Miao village, Chen Jiu changed his name to Shi Jiu and sneaked into the underground chess scene in eastern Guizhou alone. He established his power in a battle at Wangjiang Tea House, broke the chess poison, defeated powerful enemies, and swept the dark forces with his left-hand chess power. He secretly investigated the vulture's conspiracy to train the chess slave army, but he did not know that he had already been involved in a century-old chess game between the four major chess sects and the immortal chess immortal.
The chess poison gnaws at the heart, warlords run rampant, the chess sect is divided, and the family and country are in danger. Chen Jiu uses chess as his blade and his heart as his path, and step by step he transforms from an avenger to a guardian in troubled times. He uncovered the secret of the chess immortal's immortality, solved the mystery of the fate of the chessboard in the world, and used his ghost chess hand to protect the mountains and rivers, determine the right path in the world, and eventually became the most legendary chess saint in the troubled times of the Republic of China.
