Liu Er and Yaoji toured over the Untainted Land together, but Liu Er didn't forget his original intention which was to have a battle with Xing Tian from Wu Tribe, Kunpeng and Bai Ze from Demon Tribe, Four Ancestors of Human Tribe excluding Musen, the Three Royals and Five Emperors, and Zhenyuanzi from Wuzhuang Taoist Temple. Though he was defeated by Zhenyuanzi, Fuxi, and Cangjie, he had either won or ended up in a draw against the others thus earning himself a great reputation in the Untainted Land.
Especially during the battle with Xing Tian, they fought so fiercely that even the moon and sun were blocked by their movements. Both of them gained Enlightenment of the Law of War at the same time; Liu Er's Cudgel Techniques were agile and powerful while Xing Tian's Shield and Broadax complimented each other for defense and attack. This spectacular battle had caught the attention of the entire Untainted Land.
