My Brother Is a Devil, How Can I Be a Good Person?

My name is Jiang Chen, and I am an ordinary person. I have read a lot of anime and novels, and I have always known that those superpowers are fake. But when I was young, I always imagined that one day I would gain extraordinary power. Show your holiness in front of people, save people from fire and water, and then say lightly: The greater the ability, the greater the responsibility. This is what I should do. However, when my dream came true, I found that reality was completely different from my ideal. My brother became a demon and killed without blinking an eye. It seems that I am just a sundry among extraordinary people, surviving on a little bit of luck. The girl I like looks down on me and wants to slap me in the face but doesn't have the strength. I don't seem to be much different from an ordinary person? But what's the difference between me accepting my fate at the age of twenty and being a salted fish! I pray to the gods, just once! I also want to be impressed by others! But the only response was my own gasping. Then, let me be that miracle! Because people who believe in miracles are just like miracles!
