At this moment, the kitchen no longer had the stench of sheep dung, but instead had the aroma of fried fish. Yu Jiao said to Song, who was sitting under the stove, "Aunt Song, could you please help me get the medicine grinder?"

Song extinguished the fire in the stove, stood up and went back to the east room to get the medicine grinder, "Is this for external application?"

Yu Jiao nodded and said, "It's for external application." She put the roasted dried crucian carp into the medicine grinder and ground it into powder with a pestle.

Wang Mengyan was curious. Although she had been married to the Yu family for several years, she knew nothing about medical treatment. The old man had never used such unconventional methods to treat illnesses. She asked, "Can this kind of filthy food cure illnesses?"

Yu Jiao chuckled, "Of course."

Mu Yan was getting impatient as Yu Jiao hadn't returned yet. Yu Ruhai came out to look for Yu Jiao and urged her, "Why did you leave the patient in the kitchen? Uncle Mu is getting impatient. What medicine do you need? Tell me clearly."

Yu Jiao held the medicine grinder in her hand, stood up and walked towards the main hall, saying to Yu Ruhai, "I will go apply the medicine to Master Mu, while you go make two kinds of pills, Lianqiao Baidu Pills and Shuiniujiao Jiedu Pills, twenty pills each."

Yu Ruhai naturally responded, but he didn't know how to make these two pills. He was a little embarrassed and asked in a low voice, "How should these two pills be made?"

Yu Jiao was well aware of Yu Ruhai's mediocre medical skills, but she did not show any contempt on her face. She dictated the prescriptions of the two pills in detail, and Yu Ruhai took notes carefully.

The two returned to the west room. Mu Yan sat on the stool with a gloomy look on his face, looking very unhappy.

Yu Ruhai went to the shelf to look for medicine and make pills. Yu Jiao poured the powder from the medicine grind onto the paper, took a thin wooden spoon, looked up and said to Mu Yan, "Master Mu, you need to undress again. I will apply the medicine for you."

Mu Yan looked at the powder in her hand and smelled a fishy aroma. He asked, "What is this?"

"It's a good medicine that can cure your sores." Yu Jiao said calmly.

Mu Yan snorted coldly, "Whether it is a good medicine or not is not up to you to decide. Only if it can cure the disease can it count."

Yu Jiao smiled slightly and said, "Mr. Mu is right."

Yu Jiao responded so softly. If Mu Yan said anything else, it would seem that he was being unreasonable. At his age, he didn't need to argue with a little girl. He slowly took off his outer clothes.

"It will be a little painful, Master Mu, please bear with it for a while." Yu Jiao said as she scooped some medicine powder with a wooden spoon and mixed it into the sore on Mu Yan's back.

Mu Yan's face turned pale in pain and he cried out. Mu Nianjiu, who was watching from the side, felt his heart wrenched and his brows furrowed.

Yu Jiao carefully stuffed medicine powder into each sore. After applying the medicine, Mr. Mu's forehead was in pain and beads of sweat appeared. He clenched his teeth and his cheeks bulged. He didn't have the energy to blame Yu Jiao anymore.

Wrapping the remaining powder in straw paper, Yu Jiao handed it to Mu Nianjiu, "After taking the medicine, the carbuncle on your uncle's back should all break out in three days. Apply medicine to all the carbuncle again according to my method just now."

Mu Nianjiu took the medicine, took note of it carefully, and asked, "In this way, will my uncle's back carbuncle be cured?"

Yu Jiao nodded, and Mu Nianjiu looked happy. He looked down and saw that his uncle's face was still pale. He handed the medicine bag to the servant and hurried forward to help him get dressed.

Yu Ruhai had already prepared two kinds of pills. Yu Jiao handed them to Mu Nianjiu. "These are Lianqiao Baidu Pills and Shuiniujiao Jiedu Pills. Take two pills each morning and night, along with the decoction I prescribed earlier. You will see results in five days."

"Thank you, Miss Meng." Mu Nianjiu was overjoyed and helped Mu Yan stand up. "Uncle, you won't have to suffer from back carbuncle in the future."

Mu Yanyin had not recovered from the medication yet, so he was too lazy to say more. Although after this diagnosis and treatment, he had already realized that the young granddaughter-in-law of the Yu family was not a quack doctor who spoke eloquently, but she was indeed a real talent, but he couldn't save face and wanted to see if these medicines really worked. It wouldn't be too late to thank her after seeing the real effect, so he just said, "Let's go home, I'm tired."
