The Waste Genius of the System

I didn't expect that one day I would be able to travel through time. I was fed up with the warmth and coldness of human relationships. I thought it might be of some benefit to me, but I didn't expect that I would become a useless person. He was just useless, he couldn't live a good life, he was thrown into the misty forest for no reason, and he came back a month later. If you hurt me, I will repay you twice as much. If you love me, I will protect you. If you have the ability to fight me, I will be buried with you even if you die. Everyone in the world can bear it, but I cannot be touched.
