Under the bustling surface of the modern city, a thrilling adventure quietly begins due to a mysterious "orange key".
Lu Chenzhou and Su Cheng originally lived ordinary lives, but they were unexpectedly involved in a dispute surrounding the "Orange Key". This "orange key" is not an ordinary thing, but a key that hides a huge secret. Behind it involves business secrets, historical mysteries, and a mysterious organizational force that wants to control everything. The mysterious organization does whatever it takes to obtain the "Orange Key" in order to achieve its ulterior purpose. This puts the lives of Lu Chenzhou and Su Cheng into a crisis-ridden situation.
In order to protect justice and uncover the truth behind the "Orange Key", the two resolutely embarked on a journey of exploration full of unknowns. They started from the corners of the city and traveled all over ancient ruins, abandoned factories, dusty academies and other mysterious places. In the process of pursuit, they met Lin Yu, who has a strong interest in history, and Chen Feng, who leads a private investigation organization. Several like-minded people worked together to deal with the ensuing dangers and challenges.
The mysterious organization is like a tarsal maggot, constantly creating difficulties and obstacles. In the mysterious ancient building near the river, the two sides launched a fierce confrontation; in the Huguo Temple Tower, they faced a test of life and death; when they went deep into the misty valley, they fell into many traps. Every encounter is fraught with danger, and every escape is thrilling.
As the exploration deepened, they gradually discovered that the "orange key" was closely related to the mysterious power left by the ancient wise men, which was divided into multiple parts and scattered everywhere.
