Not only is Xia Ren unafraid, but he even says the dragon chair is uncomfortable to sit on, angering Li Er so much that he directly demotes Xia Ren to a commoner and sends him to experience the hardships of the common folk. Unexpectedly, Xia Ren actually runs off to become a mountain king, driving Li Er mad with rage.
