Noticing Liu Er's six quivering ears, Taoist Bodhi realized that he wasn't trying to find the Eye of Formation while angrily breaking the formation. Instead, he was tempting him to make any sound at all. Being Liu Er Macaca Mula of the Four Monkeys of Destruction, Liu Er naturally had excellent hearing and was able to notice where the Eye of Formation was by following the noise.
How cunning Liu Er was! Though he was the enemy, Taoist Bodhi had to admire Liu Er's agility. However, it wouldn't be easy to break the formation just by finding the Eye of Formation. He snorted and said, "Liu Er, I got to give you props for finding me. But so what if you found the Eye of Formation? I'm guarding it and you'll need to confront attacks from the formation as well. I shall wait and see how you'll break it."
