Reincarnated into a fanatsy world : The system forces me to fight

I was never one to interfere in other people's business.but that day all the feelings of hopeless i felt exploded, and i wanted to fight back , i got anrgy , that brief moment of hot headed heroicness cost me my life And then, something strange happened. I found myself waking up in a different world, with a new chance at life. But this time, I was determined to be in control of my own destiny. I was given a system that allowed me to level up, but it came with a catch. If I refused to fight, I would be punished.
