Eighteen-year-old high school student Lin Ye accidentally awakens the rare "eye of delusion", which can see through the true form and weaknesses of demons. He thought it was just an ordinary superpower, but he didn't expect that these eyes would involve him in a shocking conspiracy.
Under the bustling surface of modern cities, there is an unknown dark world hidden. Demons are rampant, nothingness invades, and the grudges between humans and demons are far more complicated than imagined. When the Demon Suppression Division extended an olive branch to him, Lin Ye realized that the mission he shouldered was far beyond his imagination.
From an ordinary high school student to an A-level demon slayer, from simple fighting to learning ancient sealing techniques, Lin Ye continued to grow through the experience of blood and fire. Not only does he have to face a powerful demon, but he also has to uncover the mystery of his life experience - it turns out that he is a descendant of the guardian of the ancient seal.
In Blackstone Town, he witnessed the possibility of peaceful coexistence between humans and monsters/in the city, he learned to use spiritual healing instead of simple killing. In front of the S-class demon, he realized the true way of protection.
But a bigger crisis is approaching. The conspiracy of the Void Cult, the ghost of the Demon Suppression Department, and the lost ancient civilization. Every mystery points to a shocking truth. And Lin Ye's delusion-breaking eyes seemed to be inextricably linked to all of this.
This is an adventure about growth, protection and truth. When modern technology collides with ancient magic, when the steel city merges with the world of demons, how will a young man protect the world he loves?
The door of the Demon Suppression Department has been opened for you, and the road to slaying demons begins from now on!
