Among the greatest threats facing the world in the early twenty-first century is a Chinese sorcerer said by some to have been alive for millennia. Enigmatic, possessing enough power to hold the Chinese government and its vaunted Tiger Squad at bay, and said to have designs to rule all of Earth, Dr. Yin Wu has launched several schemes of conquest in the past, only to be narrowly thwarted by superheroes. With the assistance of his progeny, the Four Sons of the Dragon, he will no doubt try again soon... and this time, perhaps only your heroes will stand in his way.
This is one of the rare Hero Plus Adventures intended for use with Champions.
