Liam had other options. Even without his Master's inheritance, he knew recipes for other poisons handy enough to use as nutrients.
However, Liam didn't restart concocting.
First of all, smoking was functional in ways that other ways of ingesting poison weren't.
Each batch of Liam's poisonous powder could last him a week. The nourishment wouldn't be as immediate as more condensed substances. Yet, it could consistently keep his core from withering, other than working as a way to recover Qi.
Liam could smoke after battles, concoctions, or training sessions without suffering debilitating consequences, avoiding remaining vulnerable in tough predicaments.
Also, Liam knew the smoking powder's recipe like the back of his hand. It was why four rounds had been enough to master its rank 2 version. It saved him time and resources he could use elsewhere.
