Su Tian, wholly absorbed in refining pills, knew nothing of Xiao Yan's departure.
At that moment, nothing existed before Su Tian but the endless process of refining pills.
Under this frenzied refining, Su Tian's soul power also continued to grow, albeit slowly, and had already broken through the realm of a Third-Rank Alchemist.

In just three short days, the ingredients Su Tian needed to refine pills had consumed a third of the Mittel Family's stock.
Although the consumption was enormous, the profits the Mittel Family earned were also considerable.
With Su Tian's alchemy, his success rate had actually reached a terrifying ninety percent. In other words, nine out of every ten attempts succeeded!
