Gu Xuan, who received a mysterious bamboo slip when he climbed Mount Everest, came to the prehistoric world after his death, and his remaining soul accidentally merged into the first human body created by Nuwa using the soil of the Nine Heavens. He saw that it was cumbersome for Nuwa to knead earth to create a human being, so he suggested that he use gourd vines dipped in mud and thrown to help Nuwa accumulate merit and become a saint. As the first human race and a hero, he was awarded the title of Human King and started the rise of the human race with the treasure of the road.
