The Daoist Equal to Heaven learned that the Water Monkey Great Saint Wuzhiqi's physical body had cultivated the Corpse Way and been captured by the King Bodhisattva, so he wanted his brothers to help him take back that body.
What is the Corpse Way? The so-called Corpse Way is when a corpse attains the Dao. Wuzhiqi's Primordial Spirit had perished, but his physical body was strong. The body absorbed the spiritual energy of heaven and earth day and night and became a Corpse King. It developed spiritual wisdom, transforming it into an immortal being of the Dao of Immortals. This is the Corpse Way. There's a saying that rats have their own paths, and snakes have their own ways. With the Great Dao having three thousand pathways, which one can't be cultivated? It is said that "a scholar is of no practical use," but Confucius with a single command, a single word, banished the Buddha of Immeasurable Life from Luoyang City.
