True enough, someone else was able to notice Yao Ling's power from afar. Rong Jie had long gone, so it wasn't him. It was the enemy. Aunt Yue's power could only be felt by Rong Jie because of their bond, after all, she already had the skill to cover it up.
However, Yao Ling was a newbie and she didn't learn how to cover it up from her grandmother. She was able to use the power was already good enough ah~!
Even Yao Ying could feel the fluctuation of Yao Ling's power in the air, so any person with high martial art skills must have been able to feel it. They could easily differentiate it with qing gong because the power essence was quite different.
