Just as Ye Xuong said, Ye Xuong and Tian Qi played a prank on Ye Tian to test their mastery of the technique to conceal their presence.
Both Ye Xuong and Tian Qi are skilled martial artists with high aptitude, so when Ye Tian taught them how to gather their internal energy into their Dantian and gradually cool it down to make their presence completely hidden, they quickly mastered it.
After just one night, they were able to skillfully hide their forms, so Tian Qi came up with the idea to spar with Ye Tian.
Although Ye Xuong initially refused, he also wanted to know how much he had improved, so he agreed to Tian Qi's unreasonable request...
After Ye Tian entered the room, Ye Xuong and Tian Qi perfectly concealed their presence, so that even Ye Tian didn't detect them at first, giving Ye Xuong and Tian Qi the opportunity to strike.
Ye Tian is the leader of Night King Hall, so naturally, Ye Xuong dared not be too forceful, making it easy for Ye Tian to dodge.
