In the bustling, dazzling city of Silvermoon, neon lights and streams of traffic weave a vibrant urban panorama beneath the night sky. Yet in the city's shadowy corners, a horrifying legend quietly spreads, like a venomous snake lurking in the dark, ready to deal the peaceful city a deadly blow at any moment.
They say that every night at midnight, eerie roars and howls echo from an abandoned factory on the outskirts, as if hellhounds were prowling inside. A passionate, curious young man named Ain hears the tale and boldly invites Bo Sang, a mechanical genius, and Qiao Lin, a yoga instructor with keen senses, to join him in searching for the truth.
The three step into the rust-stained, weed-choked factory, and are instantly enveloped by a chilling, sinister atmosphere. Under the flashlight beams, the old machines look like ferocious beasts. Then, with a low growl, a hellhound radiating an eerie red light appears. Its arrival is like a boulder thrown into a still lake, sending out a thousand ripples.
During the fierce battle, Ain and the others are driven into a desperate situation. At the crucial moment, Kai, Lina, and A Qiang arrive in time. Each puts their strengths to use as they fight the hellhound to the death. At last, working together, they manage to defeat it.
But that is not the end of the matter. Instead, like a line of dominoes, it sets off a series of shocking events. While investigating, Ain and the others discover that the hellhound's appearance was merely the tip of the iceberg in an evil conspiracy known as Project Shadow. A mysterious and enormous dark force has been quietly laying its plans, intent on using the hellhound as the beginning of an attack with biological weapons on the heart of Silvermoon City
