Jiang Chen is the famous sick sixth prince of the Great Xia Dynasty. During the day, in the eyes of outsiders, he was powerless and a useless person who was incompetent in both writing and martial arts. But no one would have thought that after guarding the imperial mausoleum for twelve years, he accidentally obtained the inheritance of the Divine Dragon Cauldron and learned the Yin-Yang Divine Art, which made his talent different from ordinary people. He single-handedly created the Palace of Hell, which frightened Daxia and surrounding dynasties, and he himself was nicknamed the Living King of Hell because of his decisive killing at night.
