Reborn, Only to Encounter a Great Plague

I was reborn, but why am I due to be dragged to the marketplace and beheaded tomorrow!?

I barely escaped with my life, only to discover that this world is about to descend into chaos under the assault of a plague, and I have just 100 days left to live.

Why am I the “chosen one”!? I’m just a lowly pawn, and I have to survive while investigating the plague’s origins if I want to stay alive a little longer.

Fine! Not only will I survive, I’ll marry a princess, become the richest man alive, and lead all of civilization into a new age!
