Blade Heart

Set in the early reign of Ming Emperor Wanli, the masked and mysterious Jinyiwei Captain Yuwen Feng serves the eunuch Zheng Cheng in his power struggle against rivals Zhang Juzheng and Eunuch Feng Bao when his investigation into an attempt on the Emperor's life leads him to encounter one Mrs. Wang, the widow of a private security firm owner. As it turned out Yuwen is in fact a Wu dang disciple by the name of Ling Feng who, 20 years prior was married to Tong Bik, the daughter of one of two prestigious sword smith clans in the capital. Their lives are uprooted one fateful night when the Tong clan are framed for treason and sentenced to death with all believing to have perished but Ling. Admiring his swordsmanship, Zheng Cheng (who is the director of the Jinyiwei) offered to spare Feng from execution and provide a new identity in return for his sworn loyalty for the next 20 year after which Ling would be permitted to seek revenge on the Sima sword-smith clan which he is told are responsible for the Tong clan's extermination. Having accepted the deal, Feng wears a mask to hind his identity while rising through the ranks under Cheng completely unaware that his wife Tong Bik is in fact still alive and also seeking revenge on the Sima clan. Having given away her and Feng's child for this endeavor, she eventually remarries a security bureau officer, having a second child with him before leading their bureau to the capital in his dying years as Mrs. Wang.

Recognizing his former wife while his mask keeps his identity from her, Feng is forced by his yet to expire contract with Cheng to watch from the shadows as his wife reestablishes a sword forgery in the capital and challenges the position of the Sima clan while planning to assassinate the elder Sima brother, Sima Yi who is believed to have masterminded the Tong's fate. The separated couple is however faced with further challenges as they come to find their past has returned to haunt them with Wang's first son unknowingly becoming entangled in her plot for revenge while Feng comes to find out just deep the plot against the Tongs are as he begins to question his trust in Cheng.
