My Undercover Mission Failed, but My Husband Is a Madman

Ruan Yunzheng was a spy sent by the immortal sect to the demon realm. She lived up to expectations and became a regional lord there.

She completed many missions brilliantly. Her one mistake was getting involved with Xue Jiangchen.

Xue Jiangchen ruled the Fifth Prison of the demon realm and commanded an army of bone soldiers. A beautiful madman, he was obsessed with collecting things.

He was arrogant and cruel, ruthless in his methods, and nearly pathologically obsessed with the male lead of the book.

After Ruan Yunzheng appeared, she became the object of his new craving and desire.

Later, Ruan Yunzheng helped the female lead of the book complete her mission in the demon realm, but her own identity was exposed.

Just as she thought Xue Jiangchen would kill her for it, he...

proposed to her.

The arrogant madman who stood above everyone else, untouchable and conceited, bowed his head to her.

"Don't go back, Ruan Yunzheng." He lowered his eyes, his deep gaze filled with her. "Or I can go with you."

* A fearless, bold spy who is only afraid of madmen x a beautiful, tragic, powerful villain trapped by his inner demons
