My Sister from Zongman

My name is Su Quan, and I have traveled through time. I have a system, I have a cheat, it has no lower limit, but please ignore it. And I also shoulder the responsibility of an older brother. There are many younger sisters waiting for me, but I am really not a sister-controller. I was just forced by a system with no moral integrity and no lower limit. Teacher Eromanga and Izumi Kirisa: Brother, are you really not a girl-controller? Then why so many games like that. This is a heartwarming story about many sisters being saved by their brothers.
