What is the minimum defense against the small drill wind in the Monkey King?

Flies. Wu Cheng'en's The Journey to the West is one of China's four classical novels, which mainly tells the story of four masters and apprentices in the Tang Dynasty learning from the West. In the novel, Wukong looked around and heard the thunder and the bell, so he found a small diamond wind, then turned into a fly and hid it next to his hat. At first, the Monkey King heard Xiao Zuifeng say, be careful that Monkey Sun will turn into a fly. He thought he had found out, but it turned out to be his least defensive joke.
