My House of Horrors我有一座冒险屋

I see, in exchange, I want your help in looking for one. It's about a kid that gains the power of the god, Chaos, who's basically the parent of the other main gods (unbeknownst to them), and this kid goes on to join an academy/school I believe and something happens between him and a few other students with him injuring them and having his power sealed by a teacher. I can't remember all of the details since it's been god knows how long since I've once read this novel, but if you've read far enough, he has the power to make avatars and give them various tasks, like learning something, and he can absorb them to learn that knowledge. He also ends up meeting a few other gods/deities, with one being the God of War I think. Sorry for the long description, but I want to make it as detailed as possible to narrow down the options
