In 1938, he was duelling with Yamamoto Kazuo, a major of the Imperial Japanese Army, when they were interrupted by Cheung-San, the progenitor of all vampires.

During this time, Fong meets Ma Siu-ling, the heiress to a clan of sorcerers dedicated to ridding the world of evil supernatural beings.

Meanwhile, Yamamoto has become the influential boss of a big company in Hong Kong and has a small group of vampire followers under his command.

However, a sorcerer called Rahu later resurrects Yamamoto and controls him to do his bidding, preparing to carry out a ritual during a blood moon to dominate the universe.

At the end of the second season, it is revealed that Pangu, the creator of the universe in Chinese mythology, is not a single entity, but a clan of divine beings who are all first-generation vampires.

Faced with these problems, Chan decided to make bold changes to the script and create a new character – Ma Siu-ling, a female ghostbuster wearing high heels and a miniskirt who is greedy for money.
