”What is justice? What is evil? If given a second chance, I would no longer care about the opinions of others and only seek immortality.“With a cry to the heavens, Dusk Vale met his tragic end.But fate had other plans. He was granted a mysterious power that sent him back 300 years to the moment everything began.In this new life, he would live without concern for the judgments of others. No more restraint, no more hesitation — he would use any means necessary to achieve true immortality.What is the best villain? In my opinion, it is someone who does a lot of evil but is still considered a good person by some people. Someone who never really thinks about others but has many people who are loyal to him.Can one person defeat the entire world? Stupid, humans are born on the same level; surpassing one person is already not easy, let alone surpassing all of them combined. That is why Dusk will absolutely not act alone in this life.
