The Su Cheng is the Incense Master of the Yellow Lotus Triad.
The Incense Master Su Cheng is a powerful mage. Every day before dawn or after sunset, he leads the rest of the Triad in "Tai Chi" exercises. Rumor among the members and others is that Su Cheng is a vampire, as he is rarely seen in daylight.
The rumor is true, Su Cheng is an ancient vampire who is under the control of Zheng Li Kwan. Which is due to his possession of an ancient Chinese vase containing the vampire's Hidden Life. Su Cheng has been responsible for the mysterious deaths of many of Zheng's foes.
