I Freeze the Undead in a Foreign Land

Long ago, Song Dingbo of Nanyang caught a ghost in Wancheng, turned into a sheep, and sold it for 1,500 coins. Today, Zhang Yangping, an apartment ant, catches ghosts in another realm, using divine power to freeze undead spirits and make ice cream to sell. Crushed by his mortgage and car payments, Zhang Yangping enters another realm by a twist of fate and is rescued by Patriarch Tang Sanzu of the Three Sages Mountain. He becomes a divine envoy to the mortal world and receives a magical artifact, setting out on a path of ghost hunting, upholding justice, and freezing undead spirits!
