In the cold Taoist temple on the top of Qingluan Mountain, there is an eighteen-year-old genius Taoist nun Shen Lingsu. She is like a god in calculating, suppressing ghosts and channeling evil spirits, but her master declares that she is destined to bring death, and she needs to go down the mountain to find a baby to solve the problem.
The ancient jade lock entrusted by the master was a token of Xie Jinci, the young master of the Xie family in Beicheng. And this heir to a top wealthy family was born with a life-threatening disease and would not survive until thirty. Only Shen Lingsu's Dao roots can preserve his life and eliminate evil spirits. With a contract, the two became a nominal couple. When they first met, one was a little Taoist nun who retreated from the world to live in peace, and the other was a gloomy, taciturn, sickly young man, with no troubles in his heart.
He shielded her from the wind and rain of the world, and she drove away the evil spirits that haunted him. She started a live broadcast to tell fortunes and catch ghosts, and became the "top metaphysics" sought after by the entire Internet; he was strategizing behind the scenes and clearing all obstacles for her. The gentleness under the iceberg gradually appeared, and Tao's heart also quietly melted with warmth.
The jade lock that Shen Lingsu carried with her was originally the spatial treasure of the hidden family in the sky. As her relationship with Xie Jinci deepens - from the alienation at first meeting, to the trust of sharing weal and woe, to the deep love of life and death - the power of the jade lock is unlocked step by step: from the initial function of collecting objects to ward off evil, to the later rejuvenation and healing, sealing of evil spirits, and even the ability to trace dust-laden memories.
This mysterious power not only helped her advance in the path of metaphysics, but also guided her to uncover the old case of her family's annihilation. Little did he know that in his eyes, there was only the little Taoist nun who looked weak but was actually tough.
