Lin Xi's ability to make pills was taught to him by the old man since childhood.
The old man claimed that this was also to give him a bit of survival ability for when he was thrown into a perilous forest alone.
After all, when injured, finding some herbs to refine into pills would be quite effective.
Back then, Lin Xi didn't believe it and thought, "Why didn't you refine some for me in advance when you threw me in there?"
Hmph, it was clearly just the old man being lazy.
As for now, using an iron pot for alchemy and natural gas to provide high temperatures seems like a bizarre method, since in everyone's impression, alchemy surely requires a pill furnace and specialized firewood.
But for Lin Xi, where can he find those things now?
Besides, for everyone, pill refining is just a deceptive trick used by Daoists.
Even the Shangguan family doesn't have any concept of pill refining.
