After Being Bound to the System, the Police Academy Team Was Forced to Forget Everything

When a magician was having a great time in the police academy and suddenly picked up a forum system... Magician (according to the forum, he recalled his experience in the third dimension before time travel, and found that he couldn't pull it out in the police academy group that killed four out of five, and his eyes were vacant): Tongjiang, do you think I should find a way to kick the shit out of these four guys? There is absolutely no way to imagine these guys looking like gray photos. System (very calm): No problem at all, you can do whatever you want. Magician (thinking seriously): First of all, all the dangerous things they can handle must be taken care of by me. After all, I am not afraid of these dangers. Then they should let them forget about my existence first. How about I learn from Hermione? Like forgetting everything or something. System (lost his composure for a moment):? ? ? ! ①The protagonist is a three-dimensional traveler. ② I used to think that this world was the world of Hogwarts. I followed the trio of saviors to kill the faceless man with the Avatar, and then when I retired to reality and wanted to be an ordinary person, I came into contact with the five-person group of the real police academy. ③After having fun with them for a while and becoming close friends, I found a forum system and discovered that this world seemed to include the world of science. ④The protagonist finally decided to take advantage of it, so he gave the five members of the police academy, the instructors and others a detailed version of forgetting all their memories of him. ⑤This article is the story before, this and after. ⑥Finally, this is my first time writing this, so please let me know OOC. (In short, I paid for the cover of this book, and my friend urged me to add it) Purpose: In order to protect his best friend, he kicked off the lunch box and created a sophisticated version of forgetting all those who knew about it.
