Rusty Blade in Troubled Times

He was once the abandoned son that his family sold for bread, I was once an ant surviving in troubled times, Now, he is the vicious blade that makes the entire world of immortality tremble - Blood Shadow. The righteous path regards him as a devil, while the demonic path fears him as a ghost. But he just wanted to keep the last bit of warmth in his heart amidst the endless killing. There is no destination in this world, so I will find my own way back.
