Yun Jiao came out and took a bath again, and by the way, had the soldiers carry out the qinghao.

The soldiers didn’t think much, carrying the sacks out, thinking they were collected by the Magistrate from the city.

The next day, Yun Jiao had the soldiers soak and wring the juice early in the morning.

After finishing, she and Cai Ping split into two groups, carrying the medicine out of the city.

After they left, Prefect Wu heard that this medicine could prevent malaria, so he quickly had people follow Yun Jiao’s method, gathering qinghao, extracting the juice, drank a bowl himself first, then had everyone at the government office drink it, placed the medicine outside the government office, issued a notice, and had government officials beat gongs along the street, calling the citizens to drink the medicine.

On the next night, Yun Jiao was coming in and out again, transporting qinghao and quite a few mosquito-repelling herbs.

Then she asked the soldiers to make herbal packs with her.

The herbs used were cut into one or two-inch lengths, unable to be made into herbal balls, and could only be wrapped in yellow paper.

The Forbidden Army also listened and followed Yun Jiao’s lead busily.

Before they came, the Duke had instructed them to ensure the safety of Doctor Gu, stating that if Doctor Gu were to get even a slight injury, they would be dealt with according to military law.

Therefore, they were all afraid of Yun Jiao doing any heavy work. As soon as she started, someone would say, "Let me do it, let me do it."

For several days in a row, Yun Jiao worked on medicine during the day, made herbal packs, and transported various herbs at night, nearly exhausting her.

The number of people drinking medicine inside and outside the city increased, and she had to transport herbs for several hours each night to meet the basic needs of the people.

Every time she moved herbs, Yun Jiao would call Captain Fang and another soldier.

She estimated that they must have noticed something unusual, yet they wisely remained silent.

At this time, Yun Jiao decided not to hide anymore, as the conditions didn’t permit it, and quickly curbing this wave of infectious disease was most important.

Returning to the government office at noon, Prefect Wu came over with a smile, "A batch of flower dew was shipped from Xiang City, said to have mosquito-repelling effects, it’s really timely rain."

Yun Jiao replied calmly, "It was produced in my workshop and I instructed them to send it over before I left."

Prefect Wu felt somewhat embarrassed, he had sent someone to inquire with the Forbidden Army over the past few days and only then realized Yun Jiao’s great reputation in Xiang City, having cured the Empress Dowager, treated the Emperor Emeritus, and supposedly even revived several dead people, no wonder the Emperor chose her over the many Imperial Physicians in the palace.

Seeing these Forbidden Army soldiers following Yun Jiao in and out of the city every day, seemingly none of them contracting malaria, Prefect Wu became bolder, approached Yun Jiao, and cupped his hands, "Thank you, Doctor Gu, on behalf of the people of Yangzhou, thank you."

Yun Jiao suddenly looked at him with a change in expression, "Prefect Wu, there’s a flower-foot mosquito on your face!"

Prefect Wu’s face changed, quickly reaching out to slap his face randomly.

After a few slaps, he looked at his palm and found nothing.

He suddenly suspected Yun Jiao was tricking him, but he had no evidence.

At this time, Yun Jiao added, "Mr. Wu, it’s best not to swat mosquitoes when you see them, try to drive them away. Randomly swatting may push the mosquito’s proboscis into your skin, and even if it dies, there’s still a risk of infection."

Mr. Wu hurriedly cupped his hands to Yun Jiao, "Thank you, Doctor Gu."

He rushed urgently toward the front of the government office to grab the flower dew; there were mosquitoes even in broad daylight, and he needed to arm himself quickly.
