Cannon Fodder's Death World

When I woke up from sleep, I found myself on the roof of an ancient ruined temple. I almost fell to my death! I was ruthlessly abandoned by the master of time travel, and finally made a conscious discovery. He gave me this unique martial arts secret book, but it was written in Japanese! ? Then I was chased by monsters. Are you trying to kill me? Do you need cannon fodder just after wearing it? Finally learned the martial arts secrets and destroyed the monster. I wanted to live a carefree life, I didn't expect a series of troubles to come to me, I wanted to be saved by a hero, but actually I saved others first. I wanted to be arrogant for a while, but in fact I was betrayed every time! The face is full of bullshit!
