The aloof military doctor arrives at the unit, and the tough guy can't sit still.

Director Liu was so angry he could only glare helplessly, but because of his position and fear of the negative impact, he dared not openly argue with Aunt Lü. He could only grumble indignantly.

"Shrews, you're a bunch of ignorant shrews. People like you are only fit to run a roadside stall your whole lives."

"Director Liu, a five-cent commission is already our biggest concession. Be careful not to bite your hand if you make too much money through dishonest means," Xia Qiuran continued.

Director Liu pointed at the two of them, gritting his teeth, "They don't know what's good for them."

Having studied pharmacology, he naturally understood that Xia Qiuran's plaster was made with genuine ingredients and could truly cure diseases. If it weren't for the fact that the plaster he used to promote was constantly being sought after because it was expensive, ineffective, and caused allergic reactions, which annoyed him, he wouldn't bother coming here to waste his breath on a bunch of country bumpkins.

"Five cents a patch? You're charging now?"

Just then, the old man who had taken Xia Qiuran's free plaster earlier came over and said something after seeing that the free sign had been replaced with a sign that said 50 cents a plaster.

"Yes, sir, we were having a promotion to let more people know about our plasters. Now that the promotion is over, the plasters are back to their original price." Seeing the person asking, Aunt Lü immediately stepped forward and explained, repeating what Xia Qiuran had taught her.

"Sir, what good stuff could you possibly get for free? If you really want to get better treatment, don't skimp on those two dollars. Only medicines from state-run pharmacies are legitimate and reliable." Before the old man could speak, Director Liu added sarcastically.

The old man turned his head and looked at her. His eyes seemed to dim a few shades. "I know you. You're the director of the state-run pharmacy. The woman next to you is a sales clerk at the pharmacy. She's the one who introduced me to another type of plaster last time."

Xiao Li straightened her chest and stepped forward. Last time, she had tricked the old man into buying medicine with just a few words, and she didn't believe he wouldn't take the bait this time.

"Grandpa, you get what you pay for. She's only selling it for 50 cents. The cost of the herbs in the plaster is at most 10 cents. The one I recommended is the most reliable."

The old man sneered, "Have you ever used that plaster you introduced me to last time?"

Xiao Li's eyes darted away. That plaster sold for 80 cents, and they got a 40-cent commission. As far as she knew, the boss would also make 35 cents. How could she dare to use that kind of plaster? So she forced a smile and replied, "I don't have arthritis, so of course I've never used it."

"What nonsense are you spouting if you've never used it?" The old man's voice suddenly rose, his eyes sharp and full of anger, as if he were pouring out all the anger that had been building up inside him.

"I only used that lousy plaster twice last time, and my whole body started to itch terribly. I thought I had some serious illness. Later, I went to the hospital and spent nearly 20 yuan on various tests. It turned out that I had been poisoned by expired and rotten herbs."

"In the end, it was the two plasters they gave me that cured my arthritis."

"If anyone ever tells me again that cheap medicine doesn't cure diseases, I'll kick them and cripple them with this old leg of mine with chronic arthritis." The old man glared and said it all at once, looking as if he wanted to devour the two men.

"You, you can't falsely accuse an innocent person. How can you be sure that the problem lies with the plasters we sold?" Director Liu stammered, pushing up his glasses.

"Director Liu, let's not bother with an old man," Xiao Li quickly said.

They know the quality of the medicines they sell, and if things get out of hand, they'll probably be in deep trouble.

"That's right, why waste words with these ignorant people? Old man, you'll risk getting a leg ulcer if you use such cheap plasters." Director Liu scoffed.

The old man put his hands on his hips and said, "You guys always say such heartless things, be careful your butts get rotten."

"How vulgar."

Director Liu choked on his words. Seeing that more and more people were gathering around them, and not wanting to affect their future earnings from selling medicine, the two of them could only leave indignantly.

The old man spat and turned to Xia Qiuran and the other man with a guilty look on his face. "Young comrades, I'm really sorry. I believed their nonsense and thought that if you sold it cheaply, it must be bad."

Xia Qiuran smiled and replied, "It's alright, sir. Getting cured is the most important thing. How is your arthritis now?"

The old man looked at his leg, which ached so much that he could barely walk, and said with a worried expression, "Before, when the weather turned cold, it would hurt terribly, and I couldn't even straighten my leg when I walked. The two plasters you gave me helped a lot, but I still can't walk too much."

"Grandpa, let me take your pulse again." Xia Qiuran glanced at the old man's legs and noticed that one of them was shaking violently. She gently placed her fingertips on the old man's wrist and diagnosed it in a short while.

"Grandpa, do your legs hurt terribly every night? Sometimes you even fall down for no reason. Your knees are always cold, and you occasionally feel numb and heavy. Sometimes it's so bad that you have to lie down for half a day to feel better."

"Yes." The old man nodded immediately, his admiration even more evident in his eyes. He had seen doctors before, but none had ever been so detailed or accurate. He never expected that this young girl would have such superb medical skills.

Xia Qiuran: "Sir, this is caused by cold and dampness entering your meridians, plus bone pain due to the long duration of the condition. Relying solely on plasters will only treat the symptoms, not the root cause. I'll write you a prescription, and you can go and get the medicine yourself. If you find it effective, come back and pay me a consultation fee. If you find it ineffective, just consider it as me talking nonsense."

The old man's face showed even more shame after hearing this. "Young comrade, I've already done something foolish once before, and you didn't hold it against me and even gave me free ointment. How could I not trust you now? How much is the consultation fee? I'll pay it right now."

"Alright, the consultation fee is one yuan." Xia Qiuran nodded in reply.

The old man readily pulled out his wallet and then said, "Okay, give me a few more plasters."

Xia Qiuran quickly stopped him, saying, "Sir, if you take that medicine, you don't need to use this plaster. It's more money for the same effect, so it's not worth it."

The old man paused for a moment as he paid, surprised that Xia Qiuran was so considerate of her patients. Not only were the plasters of high quality and low price, but she was also such a good person.

"Young man, actually my wife also has arthritis, and I'd like to take some plasters home for her to try first," the old man said.

"Alright, how many do you want?" Aunt Lü asked quickly, afraid that Xia Qiuran would refuse again.

Old man: "Give me twenty plasters first."

"Sir, five patches are usually enough. If it doesn't get better, you'll need to go to the hospital for treatment," Xia Qiuran interrupted again.

Aunt Lü, standing nearby, frowned anxiously, fearing that she might have missed buying fifteen doses.

"Give me twenty plasters, I'm afraid this good plaster will be sold out if I buy it again." The old man took out eleven yuan and gave it to Xia Qiuran. "Young comrade, keep up the good work, you have a bright future." He then picked up the plaster and looked at it with satisfaction in his eyes, as if he had bought something extremely valuable.
