Twenty-eight years ago, Mo Shitian first knew Su Ruhua. As it was a time of perpetual troubles for the Mafia, the young Mo Shitian assassinated his adoptive father and took control of the Mafia by force. In the few years that followed, he ran the Mafia with an iron-fist but had to fight against the existing powers within the Mafia thanks to problems the previous godfather of the Mafia left behind while he cultivated a new power base.
At the age of fourteen, he took control of the Mafia. In his few years in power, he crossed several members of the underworld. Although the Mafia then was the top dog of the underworld, Mo Shitian encountered several assassinations within and out of the Mafia.
When he was eighteen, four full years after he took over the Mafia, Mo Shitian unintentionally encountered Su Ruhua when somebody attempted to assassinate him in a pub. With Su Ruhua's help, he escaped the scene.
They hence became good friends and often remained in contact.
