The black medicinal liquid in the pot bubbled as it emitted steam, gradually becoming lighter and lesser with Lin Xiaoguai's constant stirring until it finally cleared completely, revealing the dregs of the used medicinal ingredients at the bottom of the pot.
She exhaled, turned off the heat, and took out a filtering cloth while demonstrating, "The next step is the final one. We need to filter out the dregs from these medicinal liquids before they cool and solidify into an ointment, and then transfer it into the containers we need."
She secured the filtering cloth over the mouth of the pot and then poured the medicinal liquid into the wooden square boxes she had prepared beforehand. By the time she finished pouring the liquid, the first box of ointment had already completed cooling and solidifying.
