In society, I, Brother Cao, am ruthless and don't talk much! This is an era where if you don't eat people, you will be eaten by others. Strength is king! "My strength comes from the system." Brother Cao looked arrogant. "You don't understand the world of the system. Your strength comes from the unknown that you haven't opened the permission for yet." The system said with a stern look.
