Lin Qiye is a handsome and capable operative for the Peace Affairs Office, specifically assigned to Squad 136 within the Night Watch organization. His primary duty involves eliminating mysterious creatures that threaten human safety. Despite his professional competence, Lin Qiye leads a relatively ordinary life, unaware of the deeper supernatural machinations surrounding him. He suffers from recurring physical ailments, such as unexplained mosquito bites and body aches, which he dismisses as mere health issues. His world shifts dramatically when he encounters An Qingyu, a brilliant but eccentric young man with a background in forensic science and a peculiar interest in mysterious creatures.
An Qingyu is not merely an ally but a secret observer with obsessive tendencies. He has installed listening devices in Lin Qiye's belongings and secretly visits him at night while he sleeps, engaging in intimate acts that Lin Qiye attributes to vivid dreams or physical discomfort. An Qingyu possesses a unique ability called the Forbidden Domain, allowing him to dissect and replicate the powers of defeated mysteries. This power makes him an invaluable asset to Lin Qiye’s missions, yet his true motivations remain shrouded in a complex web of obsession and protection.
The narrative unfolds through a series of supernatural cases, beginning with the Nanda Serpent Demon incident at Tomato University. During this mission, Lin Qiye and An Qingyu form a tactical partnership. An Qingyu guides Lin Qiye’s aim during combat, creating moments of physical closeness that Lin Qiye interprets as professional assistance. The duo successfully identifies and eliminates the demon, revealing An Qingyu’s sharp deductive skills. However, the case also exposes An Qingyu’s hidden laboratory in the sewers, where he stores specimens and conducts unauthorized experiments. Instead of reporting An Qingyu, Lin Qiye chooses to overlook his transgressions, establishing a fragile trust between them.
As the story progresses, the stakes escalate with the appearance of Loki, the God of Mischief. Loki reveals a catastrophic secret: the city of Cangnan was marked for erasure by the Outer Gods ten years prior. Lin Qiye’s existence as the dual-god proxy is the sole factor keeping the city intact, but this protection only works within Cangnan’s borders. When Loki lures Lin Qiye out of the city, the threat of total annihilation becomes imminent. Lin Qiye engages Loki in battle, summoning powerful entities from his mental psychiatric hospital to defeat the god’s avatar. The fight leaves Lin Qiye severely injured, with his soul damaged and his body weakened.
Following the battle, Lin Qiye is admitted to the Fasting Institute, a secure facility for individuals with supernatural conditions. An Qingyu accompanies him, assuming the role of his primary caregiver. For a year, An Qingyu tends to Lin Qiye’s every need, including bathing and feeding him, all while Lin Qiye remains unconscious. During this time, An Qingyu’s obsession deepens, and he manipulates Lin Qiye’s environment to ensure total dependency. When Lin Qiye finally awakens, he is unaware of the true nature of his condition and the extent of An Qingyu’s actions. He attributes his physical marks to insect bites and views An Qingyu as a loyal friend.
The story concludes with Lin Qiye and An Qingyu planning an escape from the institute. Lin Qiye begins to notice changes in his own body, such as increased sensitivity, which he attributes to recovery. Meanwhile, An Qingyu continues to orchestrate events from the shadows, using his intelligence and powers to maintain control over Lin Qiye’s life. The narrative sets the stage for a complex relationship dynamic, where Lin Qiye’s innocence contrasts with An Qingyu’s calculated devotion, hinting at future conflicts as the truth behind the Fasting Institute and the Outer Gods’ threat comes to light.
