The door to the pill refinement room had been sealed for an entire three years when one day, the room finally opened with Han Li quietly emerging from within. All of his valuable demon cores had been turned into demon core pills.
For the first two years, Han Li had used all of his time to refine grade five demon core pills.
Although these medicine pills had no significant effect on his cultivation as of current, even a single one of these pills was immensely desired by Foundation Establishment cultivators; even a single pill would leave them in ecstacy.
After refining these medicine pills, Han Li's pill refinement techniques had finally ascended to a higher level. After all, even genuine pill refinement grandmasters wouldn't have the opportunity to squander as many demon cores for practice as he did. Ordinary pill refinement masters were only able to use about forty demon cores as practice in their lifetime. Even then, it was an infrequent occurrence.
