Ye Xiao very well that the Grand Elder was keeping an eye on him all the time. Of course, there always comes sometimes when the grand elder is not 'spying' on him from the dark, however, those time comes very rarely. Even when he sleeps, he sleeps under the watch of Grand Elder.
Ye Xiao ignored the Grand Elder and kept practicing.
After a short while, he noticed the sudden presence of another Martial God. Maybe, that Martial God said something too important to the Grand Elder, a few seconds later, both of them left as quietly.
Ye Xiao's figure paused sensing the elders leaving. The next moment, when he swung his fist again, it actually became even fiercer. A dignified aura spread out from his body as he erupted with shocking strength.
The Martial Arts Skill that Ye Xiao used this time was many times stronger than what he was practicing in the presence of the Grand Elder.
