The two guards, Ye Feng and Ye Chao, were both experiencing emotional struggles at this point as they continued to wonder whether or not they should inform their original master about Luo Xiao's decision to enter a secret realm.
The Secret Realm was likely to be dangerous, and no one would be able to tell what kind of scenarios their young master would experience when facing it, but they also knew that if Jiang Yao arrived and wanted to stop him, then he was likely to fail.
Although Jiang Yao was the Seventh Demon Prince and used to decide everything around him, he was not a match for Luo Xiao. Luo Xiao was, although not as strong, the nemesis of Jiang Yao, as he could never go against his wishes.
Even though Jiang Yao would know that, logically speaking, such a trip to a secret realm would be dangerous, as long as Luo Xiao coaxed him a few times, he would forget about the directions of the earth and the skies, and agree to any decision he made.
