It was only when he was 6 did he get run into an encounter that changed his life. A realm above the Earth, The eastern world adopted him only to find he had the strongest spirit root found in The eastern world: 'nine flames of wonder'.

When he returned a massive cliche event was taking place on Earth. Hao Jin's cliche harem school life also began...
