At the age of five, Zhou Yang went up the mountain. After fifteen years of grueling training, he mastered four arts: martial arts, medicine, divination, and poison. Following his master’s orders, he comes down from the mountain to fulfill an ancient marriage contract.
His fiancée is Shen Muyao, the famously icy CEO of Tianhai City. He thinks it will be a marriage of convenience, but gradually discovers that beneath the neon lights of this bustling metropolis, hidden currents are at work. The ancient mystic sects, secretive people with extraordinary abilities, and mysterious organizations pursuing forbidden technology all turn their attention to Shen Muyao and to him.
Meanwhile, his eight senior sisters, who came down from the mountain a year before him, begin appearing one after another. Some wield power, while others keep to the shadows. Their arrival brings not only the warmth of a long-awaited reunion, but also clues to dangers lurking all around him. It seems everything points to the shocking event twenty years ago that made him an orphan.
When the shadow of the Netherworld Hall falls over Tianhai, Zhou Yang has no choice. He takes the legacy of the immortal mountain as his blade and the mortal world as his battlefield. His martial arts cow the wicked, his medical skills turn death around, his divination exposes hidden schemes, and his mastery of poison keeps the corrupt in check. This time, he must not only protect the icy CEO whose feelings for him are beginning to grow, but also join forces with his senior sisters to uncover the mystery of his birth and cut down the mastermind behind it all. In this steel jungle, he will write a city legend of his own.
