Noh Bo-jun, a world-renowned robotics engineer and Nobel Prize-winning physicist, opens his eyes to find himself reincarnated as the third young master of a noble family in a medieval fantasy world.

Instead of worrying about ruling his territory, he has only one thought:

"I don't even have to manage the territory? I can just focus on my research? This is paradise!"

Armed with genius-level engineering knowledge and cutting-edge scientific expertise, he sets out to revolutionize a medieval world—one invention at a time.
