Wu, Liuqi

Seven used to be the strongest assassin in the neighboring country. He can single-handedly fight against many enemies. However, during this mission, he was seriously injured and fell into the sea. After seven days and nights of drifting, he was saved by Dai Bo, but his memory was lost. He suffers from amnesia and aims to retrieve his memories with an expensive medical operation; thus, he decided to become a hitman as a get-rich-quick scheme. His assassin rank is currently 12,324, mainly due to his comedic inability to kill anything (his assassin rank used to be 1). (Source: Wikipedia)
