Upon hearing footsteps, Physician Ren looked up and, after recognizing the person, said, "Please wait a moment, Your Highness."

After saying that, he buried himself in his writing again.

And so, Lu Qiqi waited for about half an incense stick's time before Physician Ren looked up again.

He folded the written paper into a long strip and put it into an envelope.

After finishing his work, Physician Ren asked softly, "May I ask what is it, Your Highness?"

Lu Qiqi told Imperial Physician Ren about her idea of ​​purifying alcohol.

Seeing that Physician Ren's brows were slightly furrowed and his face was full of doubt, he suddenly relaxed his brows and lowered his eyes, with a look of sudden realization.

After hearing Lu Qiqi's words, Physician Ren was amazed. This was the first time he had ever heard that wine boiled several times could have such a powerful effect.

"Since the water and wine cannot achieve the effect of disinfection, let's do as the village chief says!"

The wounded soldiers' camp had a considerable amount of liquor; the large distillery in the border town would send a large quantity of liquor every year.

Lu Qiqi didn't think so. She believed that refining and distilling alcohol herself would require a lot of manpower and resources.

Nowadays, the Tatars are acting without any strategy, attacking and raiding the border passes at will. Neither doctors nor soldiers can spare a group of people specifically to do this.

She said, "I do have an idea. Why don't we come up with a method for distillation and refining, and let the distillery people distill and refine it?"

The distillery will definitely have enough staff, and they also have the skills. If we distill and purify the alcohol ourselves, we'll have to make the containers, which will take too much time.”

Imperial Physician Ren clapped his hands, "Excellent! I'll go and issue the order to leave the camp right away. Let's leave the camp now!"
