Yuanshi Tianzun: If Buddhists learn scriptures, we Taoists also send people to learn scriptures.
Tang Monk preached Buddhism along the way, which led to the growing strength of the Buddhist sect, and the Taoist sect could not sit idly by.
Immortals: Who does Master plan to send?
Yuanshi Tianzun: Aren't those three rebels in Heaven just idle? Let them escort the pilgrims.
Immortals: Who is the person who learned the scriptures?
Yuanshi Tianzun: A funny guy from the future world.
(It is a nonsensical joke and has nothing to do with the plot of "Journey to the West". It is a new route to learn the scriptures and a new story.)
