Xu Haoyu slowly opened his eyes and felt a dull pain in his head.

After regaining consciousness, he looked around in confusion and found himself sitting in a room with a strange atmosphere. The only source of light was an old hanging lamp above his head, with exposed wires emitting a buzzing sound like an restless locust.

The last thing he remembered was walking home from the Sky Eye after work. Suddenly, he felt a pain in his neck, and then everything went black...

He had been ambushed!
