A secret edict from the Dayong Dynasty suddenly issued, and Lin Xuanran, an abandoned son from the border city, was ordered to enter the "Secret Realm of Tianguan" to compete with the princes and prodigies on the fate of the country. The winner would get the dynasty's secret treasures, while the loser would have his sect destroyed and his family line dispersed. He was originally a young man with a useless lineage who could be bullied, but he held an ancient black gold seal that no one could see through. From the moment he stepped into the secret realm, he had to risk his life to rewrite the chess game of the entire dynasty.
