The Cannon Fodder's Reaper's World

I woke up from a nap to find myself on the roof of a ruined temple in ancient times. I nearly fell to my death! Then the transmigration god cruelly abandoned me. At long last, it had a change of heart and tossed me a legendary martial arts manual, only for me to discover it was written in Japanese!? Then a monster started chasing me. Are you trying to kill me or what? I’ve only just transmigrated, and I’m already going to be cannon fodder? At last, I learned the martial arts from the manual and defeated the monster. I’d hoped for a carefree life, but a whole string of troubles came looking for me. I’d hoped to be rescued by a hero, but instead I had to save someone else first. I’d hoped to act all haughty for once, but every time I got outwitted by some schemer! I’m crying buckets here!
