Dou Hun Dalu

Trash? A good-for-nothing who can't awaken his fighting spirit? A disgrace to the Luo family name? The biggest joke in Wuling province? All of this just makes him laugh!
He was spurned by his family, hated by his father, and even strangers made fun of him! Eventually, he was disowned and kicked out of the house! But losing everything caused him to become enlightened! He realized that, on the Fighting Spirit Mainland, only the strong are respected!
When his former talent returned, what others saw as genius was nothing more than a joke to him.
They call him a demon? He responds:
"Hehe, what I, Luo Chen, love to abuse most is evil!"
