Guo Xuan, an unemployed man who is heavily in debt, unexpectedly steps into a mysterious place shrouded in shadows. It seems ordinary but there are hidden dangers everywhere. In order to find out the truth, Guo Xuan disguised himself as an undercover agent and went deep into it, but found himself trapped in a thorny thicket of layers of mysteries. In order to cover up the truth of the supernatural incident, the villain organization obstructed Guo Xuan's investigation in every possible way and sabotaged his acquisition of supernatural resources. Guo Xuan hides the identity of the system owner. Once exposed, he will be frantically hunted by the villain organization.
Not only that, Guo Xuan's initial abilities were insufficient and he was unable to deal with powerful supernatural threats. The resources of the mysterious land were exhausted and he was disciplined by the villain organization, which severely restricted his development and freedom. Guo Xuan was also misunderstood by the local people as an accomplice of the villain and faced a crisis of trust. At the same time, the supernatural power is about to get out of control, and Guo Xuan must solve the complex mystery within a limited time to prevent the disaster from happening.
In this process, Guo Xuan relied on the tasks issued by the system to continuously solve supernatural events and obtain rewards to improve his abilities. However, every victory is accompanied by the injury or sacrifice of the helpers around him, which is full of bitterness. Whether Guo Xuan can resolve misunderstandings, break through difficulties, uncover the mastermind behind the scenes, and prevent supernatural disasters in this environment full of horror and suspense is still unknown.
