Chen Qingyuan, once the top prodigy of the Northern Wilderness, has been gone for a century since he walked into the forbidden zone called Tianyuan. When his soul lamp went dark, the world decided he was dead. Now, a hundred years later, he comes out of Tianyuan alive, but his cultivation is wiped out entirely and his past is a mystery. Inside the zone, a mysterious woman in red binds him to a pact and gives him two choices: marry her, or fulfill nine promises. Chen Qingyuan takes the promises without hesitation. He expects that choice to begin a miserable, grueling life, yet it becomes a journey bound to destiny and packed with wild power boosts. The 52-episode ONA mixes action, adventure, and fantasy.
