When he was twenty, Yang Xiaoyu returned to the empty old house and found only a letter on the table, written in blood-red ink: Grandpa went to look for your father. A strange symbol shaped like an eye and a keyhole shattered everything he had believed for twenty years. His father might still be alive.
The only thing he could rely on was the art of deciphering mechanisms, which his grandfather had rigorously taught him since childhood. Following the clues, he entered a stone chamber full of ancient mechanisms. All he found was a warning and a name. The road ahead was perilous, and he could not make it alone. He had to find companions.
He found them.
Yuan Lan, a solitary geography prodigy who could read the lay of the land.
Huan Huanling, a calm physician who had embarked on a dangerous journey to find missing family.
Zhong Zhenzhen, a rebellious heiress eager to prove her worth and skilled at navigating social situations.
From eerie ancient tombs to ruins deep in the mountains, they form the "Spirit Wardens." Amid interlocking mechanisms built over a thousand years and the covetous forces lurking in the shadows, they struggle to survive. Every mechanism they solve is a contest with death; every choice tests their fragile trust.
They are searching for the whereabouts of their loved ones, for a long-buried secret art of "spirit warding," and, above all, for the shocking truth behind the plans of the grandfather who left them riddles. When the final mechanism is activated, they discover that the only key to breaking the shackles of fate is the backs they entrust to one another and the hands they never let go.
The ultimate trial of intellect, courage, and trust begins.
Theme: I hope everyone can find someone they can trust with their back.
