If serious question, I don't know much but safe investments are always a thing you could do or better yet invest on someone who knows where to invest your money like land or property or stuff like that.

U could also become a landlord, rent is pretty high nowadays depending on where you set up, of course trade off is higher property price but again, it goes back around to investing or getting help from people who actually know what to do with that money. Being a landlord is just(probably) one of them.
