All My Female Disciples Want to Kill Me

With memories from my life in the 21st century, I was transferred into the body of a man named Su Bei in another world and given the "10,000x Disciple Rebate" system. All my disciples are gorgeous women with amazing attributes. Any one of them could be the main character in a novel. But they all hate me so much that they want to kill me. What on earth did the original Su Bei do to his disciples in his previous life?!! (Source: Tencent, translated)
