Starts of good but kind of falls off. Initially there is a big deal about MC having "world library" as skill, but it kind of turns into a skill that lets MC react like a isekai protagonist to things, pretty soon.Also, it seems the author hasn't really put much thought into how discoveries are done or how much impact they can have, or how hard they are to copy or accomplish.Spoiler
MC goes to his dwarf guy, tells him to make steam engine, dwarf guy does it in a day. Dwarf guy sees a gun for the first time, MC gets a gun within a few days. It honestly makes crossed the boundaries of suspension of disbelief. Not to mention MC is an idiot, MC lives in a country were power is supreme (and has suffered due to it). He gets guns, defeats am opponent and his first thought after that is to share the blueprint for guns and basically sell guns everywhere. So much for him being an advocate for peace (there is a big deal about him fighting not for war but to protect). Also how idiotic do you have to be to share the one thing protecting you?.
[collapse]Anyways, the chapters also become quite bland pretty soon, most characters don't really have any thing memorable about them (besides the robot) and the MC, once again, is a typical Japanese isekai protagonist without the isekai.
