Qin Feng's face blushed crimson, his burly stature not diminishing. At his age, to pay a "tuition fee" to a younger person like Su Han, truly made him feel unable to show his face.
But he had indeed lost, and he had even said that if he lost, he would take Su Han as his master. This...
"Doctor Qin is passionate about medicine, aiming to elevate medical skills and benefit patients, and is only too eager," Su Han glanced at him and said, "That was just a joke earlier, I hope Doctor Qin won't mind."
The "joke" Su Han was referring to was obviously about Qin Feng wanting to become his disciple.
It was not out of courtesy that he declined, but genuinely did not wish to take on disciples. The medical techniques in the "Heavenly Scriptures" were not to be passed on lightly; that was a principle.
