[Douluo Dalu] Flower of Evil

Even after living another life, Tang Yu still couldn't understand the seven emotions or make sense of human hearts. He was a demon, incapable of understanding human joys and sorrows. Until someone taught him. PS: The protagonist is a siren, the half-human, half-fish creature from Western legends, also known as a mermaid. These sirens are said to lure humans into the sea with their songs, where they drown. They're beautiful and vicious, not the kind of little mermaid who saves a prince in distress and turns into sea foam. Since the protagonist isn't human, his behavior and values are extremely twisted at first, though he gets better later on. Please don't flame the story. There are many original settings. Read the story for details. The protagonist is Tang Yu, paired with Third Brother. They are not related by blood. His Martial Soul is a siren, accompanied by the Flower of Evil Thoughts. His soul skills are based on the seven deadly sins. The golden finger is overpowered. If that's not your thing, please leave quietly. Theme: Good and evil are rewarded in kind; be kind first.
