Yun Jiao went in and closed the door behind her.
Then she slipped into the medicine storeroom.
She found the materials needed to prepare the White Medicine and put them into the grinder.
She then got the materials for Eight Treasures Eye Powder and put the raw materials into another grinder.
Yun Jiao made sure the powder wasn't ground too fine.
It looked as though it had just been milled using stone rollers.
Afterwards, Yun Jiao came out with the medicinal powder, rested for a while in the west wing, and sat in a chair, pushing the millstone a few times with her foot. Then she opened the door, intending to call Lao Jiu and Ah Tie to grind the medicine.
As soon as she opened the door, she saw the new helper, Zhou Shaoping, coming over from not far away, smiling at her, "Boss, are you preparing medicine?"
Yun Jiao nodded at him and called out loudly, "Lao Jiu, come and work the millstone. Ah Tie, use the mortar to grind the powder."
