In the climax of our crossing of the sea, I accidentally dropped my magical instrument into the sea, yada yada yada, War with the Dragon King Ao Guang. He wanted the instrument for himself as he saw it floating down towards his castle and so a war between we, the Eight Immortals, and he, the Eastern Dragon King Ao Guang, began. We won the battle easily because of Ao Guang's incompetent crustacean foot soldiers and regained my super amazing magical instrument.
