In life, Big Scar Wu was one of Hong Kong's most ruthless triad gangsters. Feared as much by those who stood against him as those who stood by him in the Sun On Yee, it was decided by the Grand Dragon that he must be stopped. Looking to send a message, they had him stabbed 42 times before feeding his bleeding corpse to the grinder at the Smiley Cat cat food plant... his final resting place, in the food bowls of the city's pet cats. It is said that if the wronged receive anything less than a proper burial, their spirit will almost certainly come back as a Hungry Ghost, damned to starve in the afterlife, feeding only on their hatred. You turn him into cat food and that's pretty much guaranteed.
With the city in chaos and its citizens possessed, Wei Shen now faces a challenge far more sinister than any before. To save Hong Kong, he must seek out the most powerful of Chinese magic, endowing him with a power strong enough to take on Smiley Cat's army of Jiang Shi and his triad ghosts.
