Amon looked at Ethan with pity, the man beside him was quite strong at the 6th Stage Spirit Core Realm, but that wasn't enough.
In the original novel, this old man was saved by Ethan thanks to his special Qi, but that was only temporary and would resurge after a month, causing him to suffer Qi deviation and become a cripple husk.
Sadly Amon didn't impress his mother in his past lives, nor did he sell elixirs.
So this clash wasn't over the elixir but was supposed to be when Ethan showed off to Alice and brought the recipe to her—then the old man saved him from having it snatched, and the two became friends.
However, Alice wasn't there; the strongest person wasn't the sick old man.
Amon had complete confidence to deal with the situation as he had already told his mother someone might try to barge inside with a strong cultivator to threaten them.
'Tsk tsk... this time it's on my turf, and my good family member Chen Fan is here.'
