Sun Wukong nodded in satisfaction and then continued to ask, "What is the origin of those three demons?"
The Sizhi Gongcao hastily replied, "There are three demons in this cave: the eldest is called the Cold King, the second is the Heat King, and the third is the Dust King. These demons have been here for a thousand years."
"From a young age, they loved to eat pastries and sesame oil. In their early years, they became demons and pretended to be Buddha statues here, deceiving the officials and people of Jinpingfu, setting up the Golden Lamps, which use pastries and sesame oil as fuel."
"Every year on the fifteenth day of the first month, they transform into Buddha statues to collect the oil; this year, after seeing your master, the demons recognized him as the body of the Holy Monk, and they have captured your master in the cave, planning to cut and fry his flesh in sesame oil in the coming days."
After hearing this, Sun Wukong nodded to himself and said, "Is that all?"
