It turns out that Divine Doctor Zhang's unexpected request was to learn the art of acupuncture from Lin Yi.
In the vast lands of Dayu, Divine Doctor Zhang was already an invincible figure, yet he was willing to learn a skill from a youngster. This spirit of lifelong learning truly touched Lin Yi.
Lin Yi appeared to be in a difficult position; he could not consider himself a top master of acupuncture, at best he was only skilled in its techniques.
Seeing Lin Yi's embarrassed look, Divine Doctor Zhang knelt down then and there to kowtow, directly performing the ritual of prostration.
"Master above, please accept your disciple Zhang Hongyun's bow!"
Before his words even trailed off, Divine Doctor Zhang respectfully bowed three more times.
The sense of ceremony was already complete; for Lin Yi not to take on a disciple would seem unreasonable.
'Oh, Divine Doctor Zhang, you're old enough to be my grandfather. With you kneeling like this, aren't you shortening my life? Oh my!'
