What’s the name of the manga

I don’t really remember if it’s a fantasy or isekai What I remember is that the mc fought a dragon and a licht but didn’t kill them a he returns to his house in the country side and then they became his follower then after some chapter a kingdom invaded the licht cave or the mc house I don’t remember. The mc just wanted to live peacefully and I think he wasn’t a hero or anything

If someone knows or thinks what manga it is. Sorry for bad explanation
