At the end of the Qing Dynasty, most of the people in the city contracted strange diseases. He Miao, who cares about the fate of the country, hopes that Zhang Xiaozhi will help him to get the treasure in the underwater underground palace. But several other forces started a big fight in order to obtain the treasures of the underground palace.

During the Northern Song Dynasty old monk Zhishan adopted an abandoned baby with a scar on the baby's belly, "Son of Wang Wen of Dongchang". Zhishan discovered that the baby was half-human and half-fox, and decided to adopt him and teach him to be kind. He named the baby Wang Zi and taught Wang Zi to recite sutras and meditate daily.
