Former Demon Realm Supreme Lord Ning Yechen grew tired of strife and secluded himself in the human realm's mountains and forests. By chance, he formed a bond with Luo Ruying and they gave birth to their daughter Yeye, bringing the softest attachment into his heart. When his wife and daughter were persecuted and faced mortal peril, Ning Yechen resolutely stepped forward, using his supreme strength to protect his family and uphold justice, ultimately exposing the plot, punishing evil, and promoting good, as the family of three returned to a peaceful life.
