Tianji Master Yun Che was lucky enough to be reduced to a slave in the destroyed Tianting Pavilion, and was bought by the enemy's young general Wei Heng. Relying on his "cobweb-like" reasoning ability, Yun Che uses the Wei Mansion as a chessboard and the world as a bet. Under Wei Heng's admiring and scrutinizing eyes, he reorganizes the intelligence network behind the scenes, uncovers the imperial conspiracy step by step, and finally makes a choice beyond personal grudges at the crossroads of revenge and rebirth.
