Moshi Wanwu Shengji Xitong

As a person from the 21st century, I was moved into the body of a man named Su Bei in a different world, with a feedback system "up to 10,000 times to take students". All my students are beautiful, and they are all very lucky girls. Each of them can become a protagonist in a novel. But they all hate me so much that they want to kill me . What did Su Bei original to his students do in their previous life? !!
