Old Madam Shen is considered a top-level master in Neijia Kung Fu. She is very knowledgeable about Neijia Kung Fu. Inner Strength is different from External Skills; to practice Inner Strength, not only must one be exceptionally gifted and physically fit, but crucially, Inner Strength is a process of accumulation that requires time to develop.
Ordinary people require at least a year from starting Breathing and Meditation to feeling their Internal Breath. Ye Qing, however, felt his Internal Breath in just two days, which is why Old Madam Shen finds it so remarkable. Anyone else would find it incredible too.
"At first, I thought it was impossible, but it's a fact, it really happened," Shen Tianjun paused and said, "Moreover, have you noticed that Ye Qing's Inner Strength is actually quite strong?"
