What? I'm Such a Hero

That day a voice asked me, did I want to be a hero? At that time, I had just traveled through time, and the original owner owed a lot of money and couldn't even afford food. I naturally refused, but I didn't expect that he would actually reward me with gold? What! ? Be, be a hero! But what the hell is course tutoring? What does psychological counseling mean? Why do I keep doing these meaningless things? Hey, I traveled through time and became a hero. Can't you give me some serious work? For example, a hero saves a beauty or something like that. System: "Okay, how about letting you transform into Akainu and defeat the evil forces? Or how about letting you transform into Uchiha Itachi and save the people trapped in the illusion?" So from that day on, I truly became a hero, and people began to spread legends about me. Serious introduction: That day, people in this world were a little strange. There was a voice in their ears that others could not hear. The voice said that he would give you super powers, but please do not reveal his existence. But the strange thing is that on that day, many people died in this world, and many people were resurrected.
