After learning from the Buddhist scriptures in the West, he became a positive result, wandering in the sky all day, and often drinking and making trouble. But one day, his head hurt again. It turned out that the Jade Emperor didn't trust him, so he put a golden hoop on him and read the hoop spell every three and a half months, which gave him a headache, fearing that he would make trouble after drinking. The Monkey King is seeking medical treatment everywhere in the sky, and the great immortals love to help him. One day, he heard that human science and technology were developed, so he went down to seek medical treatment. After a fall, he came to Beijing, and a robot greeted him and said respectfully; "Great Sage, have you come to see a headache?" The Great Sage was surprised. "How do you know?" The robot said, "There is a radar tester on the building. How can you not know? " The robot took the Monkey King to the fantasy world clinic. The equipment in the clinic is very simple. The Monkey King smiled and said, "It's impossible to cure my headache with these gadgets, right?" A professor in a white coat patiently explained, "Don't look at these little things, they are of great use! Look at those buttons. They can emit electric current, electromagnetic waves and infrared rays. The Monkey King, who is used by human beings to treat diseases, is confused by these new terms. The professor took out something that looked like a lighter. When he pressed the purple button, the Monkey King fell into a sweet dream. When he pressed the black button again, a white light "hippo chef" passed through the golden hoop. " All right. "said the professor. The Monkey King didn't feel anything strange and soon woke up. He jumped for joy when he saw that the golden hoop was gone. The Monkey King said with emotion, "The development of human science and technology is really fast. It seems that my grandson has to practice for a few more years. " He thanked him again and again, and then left.
