Take Me In, My Lord

I’m the daughter of the leader of Lingji Sect, a top killer organization. Though I’m not good at killing people, one day a strange man came to me and asked me to complete a mission for him. Strangely enough, he said I was the only one who can do the job. That is, to steal a secret letter from the man himself! Only it was the “him” from 10 years ago. Who exactly is this man? What does his future have to do with me…
Lord! take me in , 盟主大人 收留我吧
