This sentence came from the thirty-third chapter of Journey to the West. It was what Sun Wukong said when he said goodbye to Tang Sanzang. When Sun Wukong said this, it meant that if he wanted to become a Buddha, then all the demons in the world would be defeated by him. If he wanted to become a demon, then what could Buddha do to him? This sentence expressed Sun Wukong's confidence and determination, as well as his pursuit of freedom and independence.
