Jing Ping'an is reborn in the Northern Hua Dynasty as a discarded son of a marquis's household, exiled to the borderlands. After ten years of honing himself, he lies in wait like a hidden dragon. Armed with the advantages of transmigration and knowledge centuries ahead of this world, he enters the imperial court in one fell swoop, stirs up the winds and clouds, maneuvers through political intrigues, campaigns across the land, wins the submission of all four directions, and builds a glorious empire.
