Good-for-Nothing Sect Master: All My Disciples Are Female Emperors

I transmigrated to a fantasy world and became the Sect Master of a failing sect, a good-for-nothing on the verge of ruin. I was also forcibly betrothed to the notorious, cold-blooded number-one female killer. Everyone was waiting for me to die, for her to become a widow, and for them to carve up my sect. What they didn't know was that I had awakened the [Strongest Disciple-Recruiting System]. Every disciple I took in was a peerless prodigy hiding their true identity. Even my icy, aloof killer-wife was judged by the System to have heaven-defying potential and was waiting to be recruited as a disciple! When my disciples sweep across the eight directions and my hidden identity is revealed, the whole world will tremble at my presence!
