During the battle of the northern border, no less than 100 white ghouls had been killed at the Xue state defense line.
Fortunately, these white ghouls didn't know anything about formations, and most of them rushed over in a scattered manner. Otherwise, the combined forces of the 100 white Ghoul Kings would be enough to deal a heavy blow to the Allied forces of the two states.
The soul pearls of these 100 white ghost kings were equivalent to refining more than 30 batches of Foundation establishment pills.
Usually, this kind of large batch of foundation building pills would definitely require the help of a fourth-stage Alchemist, not a third-stage Alchemist.
A stage three Alchemist could only form three pills in a furnace if they were unlucky. They would be considered lucky if they could form four pills, and it was even rarer if they formed five pills. If he was a stage four Alchemist, he would be able to produce five pills in one batch, and sometimes seven.
