A brilliant romance and suspense wuxia drama

This drama is so good that I want to write a review about it I finished it in just 2 days the plot is so intriguing to find the spy/anonymous who entered the gong family and started killing from wuheng.the male lead is the least capable young master but somehow ends up becoming the sword warrior and the female lead is also a wuheng spy and ends up becoming fiancee of the male lead every character has a really great build up every character is involved and there are many plot twists and coming to the music it's also really good
