Firstly, both Ning Fan and Old Tang were absolute experts in the realm of traditional Chinese medicine, and their basic skills were evident; no one was surprised, and there was nothing particularly remarkable about it.
Therefore, people from the Chinese Medicine Family came up with this idea.
Of course, if it had been a normal person, with their martial prowess, they naturally would have spotted it instantly.
So they found an ordinary person and merely told him he was ill, without revealing what the illness was.
Faced with such a large audience, and knowing that he was ill but not the specific illness, this person would naturally develop a psychological condition.
Furthermore, facing so many people, plus having an elder from the Tang Clan treat him, this person would naturally be very nervous; under these circumstances, his pulse and breathing might vary slightly.
This wasn't due to being ill; it was purely because this person was nervous.
