Knights and Magic – Because It‘s His Hobby (FAP-67)

It was a good story That was a little like an isekai but at least not in your traditional sense. The character instead of being teleported to a new world and being overpowered, he is reborn into a new world after dying and he retains his memories, at least from what we are led to believe, and takes leaps in technology. Ending with a battle between 2 people that are over the top about robots although they view them differently.
