Jiang Suizhou, a history professor transmigrated into the frail and hated Prince of Jing, has been dealt quite the losing hand. His only bastion of hope? The captured, incapacitated Huo Wujiu, his concubine--and the general whose vengeance will end the Jing dynasty. But Jiang Suizhou's not going down with the ship! He joins hands with Huo Wujiu with a promise--protection now for protection in the future--and seeks out a physician to heal Huo Wujiu's legs. The two men's bond and trust deepens as they step beyond their mutual obligations to trade blows with Minister Pang, the puppeteer pulling the corrupt court's strings. Stained reputations, hidden motivations, and political assassinations abound as Huo Wujiu and Jiang Suizhou fulfill their promise. But is this protection alone enough to keep them both safe...and is it all they seek from one another?
