Yu Nanqing is the Prince Gong of Great Jin, once a glorious war god who conquered the Southern Barbarians and repelled the Northern Bandits. He has been paralyzed and bedridden for three years after a serious injury during the East Sea Saltpeter battle. His temper became volatile and he is rumored to have killed many maids. He is thin, pale, and covered with bedsores due to neglect. Despite his condition, he retains formidable internal energy, as shown when he blasts soldiers away with a palm strike. He initially distrusts and threatens Su Wanyan, but later protects her from the Emperor’s soldiers and even suggests a divorce for her safety, revealing a hidden gentleness.
