In terms of age, Chen Hai's grandfather, had he not died young, probably wouldn't have been older than Hu Laodao before him.
Thankfully, Chen Hai wasn't drinking tea when he heard Hu Laodao express his desire to become his disciple; otherwise, he estimated he would have, just like Old Mrs. Wu, sprayed his tea all over Hu Laodao's face.
"What do you mean by that, Old Mrs. Wu? Is what I said so amusing?"
"In our Cultivation World, it's the accomplished who lead."
"With Senior Chen's strength and realm, he's more than qualified to be my master."
"To follow the senior and frequently receive his guidance is my good fortune, my chance."
...
After wiping off the tea that Old Mrs. Wu had sputtered onto his face, Hu Laodao looked at her with dissatisfaction, glaring at her fiercely.
In the past, he had been content with the status quo and had long since lost his ambition.
