Three hundred years ago, Ling Yeshang, master of the Frostglory Sword, killed her dao companion with her own hands and severed her mortal attachments to prove her Dao. She became a cold-faced sword cultivator renowned throughout the Immortal Realm, yet harbored an obsession no one knew about.
Three hundred years later, she ventured into an ancient secret realm and came upon Mo Chenyuan, a scar over his heart. His features were exactly like those of the dao companion she had “killed,” yet his true identity was that of an ancient Demon Venerable wanted by the Immortal Realm for a million years.
He appeared at her sect’s mountain gate with an ancient marriage contract, threatening her with a life debt to force her into marriage and exploiting her sect’s vulnerabilities. Rebellious as she was, Ling Yeshang could not defeat him and was forced to sign the marriage papers.
Only after the wedding did she learn she had married the Immortal Realm’s number-one villain. Just as she was about to break the contract, Mo Chenyuan began suffering periodic memory loss due to an old injury to his soul. Every time he opened his eyes, he fell in love with her at first sight, turning into a lovesick, clingy puppy. Once his memories returned, he became his scheming self again, teasing her and getting under her skin every day. As they bickered and tugged at each other, their feelings quietly grew, and she even became pregnant with an egg containing both divine and demonic energy.
As clues hidden in old keepsakes surfaced, the truth behind her feigned death and ascension three hundred years ago slowly came to light. Turmoil erupted at the Demon-Slaying Assembly, and the mastermind behind it all kidnapped their little egg. The couple faced the crisis side by side, and in the end, the immortal and demonic realms were united as they stayed together year after year.
