Yellowstone: Wind in the Smoke - Chapter 102: Back to the Routine, Part 3

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

Hmmm… that guy looks like he might cause me problems in the future. Should I let him off for now and let him grow into someone that can threaten me….. Nahhh. *kill*-

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