Q: The staff first appears in the third chapter when the Monkey King goes to the underwater kingdom of Ao Guang, the Dragon King of the East Sea, looking for a magic weapon to match his strength and skill. When all of the traditional magic weapons -- swords, spears, and halberds weighing thousands of pounds each -- fail to meet his standards, the dragon queen suggests to her husband that they give Sun a useless iron pillar taking up space in their treasury. She claims that the ancient shaft had started producing heavenly light days prior and suggests that the monkey is fated to own it. The novel never explains how the pillar was made, only that it was originally used by Yu the Great to measure the depths of the world flood during times immemorial.
