There, biotech billionaire William Pan approaches them, requesting that they bring to him his twin sister, underworld boss Ku An Qi, a jiangshi who has been consuming massive amounts of qi to expand her supernatural powers in order to take over the world. William explains to them that he and Ku are descendants of Pangu, the being who had shaped the universe, whom the first Wu Assassin killed after he went mad with power and whose essence is now contained within two talisman: one in the possession of William and the other Tommy had found on Jenny, which had formerly belonged to Ku. William tells them that Ku had killed Jenny while searching for Kai, the current Wu Assassin, but lost her talisman in a fight with her, and that now he can use both talisman to depower Ku and restore order to the universe.
