What happens when a scientist from a futuristic world reincarnates in a World of Magic and Knights? An awesome MC is what happens!

Alternative: Leylin is transported from an advanced technological era into a medieval world— except there’s magic.

Yet strength is only a tool for Leylin, like any other. His goal, in the end, is his own.
