Shanlian de Sishen

The pure of heart Ah Dai was born into a live of thievery. One day, he was taken away by Gliss, a powerful alchemist to make a god instrument. His new fate leads him to save the life of the country's top assassin “King of Hell”. To repay him, Ah Dai is taken away by the assassin to receive intensive training. What will become of Ah Dai? Ah Dai is a very kind and soft-hearted kid. His favourite thing is steamed bun and his favourite girl is Ya Tou. But steamed buns are always in shortage and Ya Tou left him, never coming back. "What is wrong and what is right", even someone as silly as Ah Dai sometimes asks this question, especially when he was forced by a gangster to pickpocket others on the street. One day, he got a money bag full of amethyst coins from a passerby, and the coins started to talk and shine with mysterious light. "Do you want to go with me?" That rather strange handsome passerby asked him. "Can I have steamed buns everyday." "Yes, you can." And our Ah Dai joined this mysterious magician to start his fantasy cultivation journey...and eat steamed buns everyday...
