A few months ago the fishermen at the Beinan Sea happened to discover pearls in the sea. But because the sea is at the border of the Northern and Southern lands , fishermen from both places had been fighting over the pearls. As a result, several fishermen had been drowned during the fights and it came to the attention of the governments of both dynasties.
After a few letters were exchanged between the Emperors of both dynasties,they agreed to meet physically to discuss the issue. Emperor Gu Cheng Yi of the Northern Border Dragon Dynasty loved travelling and exploring new places so he found going to the Southern Dynasty for the negotiation a great opportunity for him to explore. The last time he went to the Southern Dynasty he was still a prince and now he was a forty year old Emperor,so he felt like it had been ages since he went to the South.
