九龍城砦
On June 22, 1997, before the handover of Hong Kong, the demolished Kowloon Walled City reemerged from the realm of Yin (陰界) back to the streets of Hong Kong in the living realm of Yang (陽界). The Hong Kong Supreme Feng Shui Conference (香港最高風水会議) determined that the reappearance of the walled city was a sign of an imbalance of the Yin and Yang, and if the two parallel worlds are not separated once again, great calamity would occur. To set things straight, the order of Feng Shui would need to be re-instilled in the realm of Yin. Thus the protagonist, a Super Feng Shui Practitioner (超級風水師), was sent into the Kowloon Walled City to seek and awaken the Four Symbols so that order would be revived.
