The old man never taught him, how would he know that skill?
Only by acknowledging apprenticeship and strengthening familial ties could he have the chance to learn the other person's skills.
Thus, another two years passed, and the crippled old man finally imparted all his skills to Chen Mancang.
That night, Chen Mancang respectfully poured wine for the old man. When the old man was drunk and dazed, Chen Mancang excused himself to relieve himself. When he returned, he had a sheepskin in his hand.
The old man asked him, "What are you doing with that sheepskin?"
Chen Mancang replied with a smile, "Didn't we agree that I would take care of you in your old age and see you off? I'm just fulfilling that promise, coming to see you off!"
Once touched, the sheepskin crafted through secret techniques began to shrink rapidly.
The old man struggled and screamed under the sheepskin, reaching for his smoking pipe but unable to grasp it no matter how hard he tried.
