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

At this moment, Wu Xiaona interrupted, "Mom, didn't I buy you disposable sanitary pads? Using wood ash is so unhygienic!"

"I've used wood ash my whole life and never gotten sick. It's too expensive to use it all at once. How much money do we have to spend like this?"

Yan Jun's mother immediately retorted that she came from a poor family and could not accept such a wasteful behavior of using something once and then throwing it away.

"Auntie, but it's not easy to find that much wood and grass to burn to ashes in the city these days," Xia Qiuran continued to ask.

The fact that wood ash has been used for so long is based on certain reasons. Burning wood has a certain bactericidal effect, so simply using wood ash will not easily cause illness.

"Yes, that's why I still use some old cotton and scraps of cotton," Yan Jun's mother continued.

Xia Qiuran became increasingly confused after hearing this. Many people use old cotton and scraps of cloth, so it shouldn't cause such severe pelvic inflammatory disease.

"Alright, shut up. I'll settle the score with you when we get home. You're discharged right now." Yan Jun's father was so angry that the veins on his forehead were throbbing. He scolded him on the spot.

Since it wasn't caused by the sanitary pad, it must have been something else that caused this disease. At such an advanced age, to cause such a shameful incident is truly embarrassing.

"How dare you scold me? Don't you know your own character? I'm embarrassed to say anything to you in front of the children. I think this illness is probably caused by you."

At this moment, Yan Jun's mother also became angry, pointing at Yan Jun's father with a livid face.

She has lived an upright and honest life, and she is not afraid of what anyone says. However, Yan Jun's father had a lot of scandals when he was young. Once, she even saw Yan Jun's father sitting on a park bench with another woman, chatting and laughing. Now he dares to say such things about her.

"You crazy woman, you have a dirty disease yourself and you want to blame others. I think you deserve a beating."

Enraged, Yan Jun's father reached out to hit Yan Jun's mother.

Several people inside the house quickly came up to break up the fight.

Yan Jun's mother retorted just as fiercely. "You're the one who's unclean. I don't know which slut you've been messing with outside. I disinfect my underwear with DDT powder. What makes you think I'm unclean?"

Upon hearing this, Xia Qiuran was completely stunned.

"What? You're using pesticides for sterilization and disinfection?"

She could hardly believe her ears, thinking she must have misheard, or that Yan Jun's mother had said something wrong.

Pesticides are highly toxic substances, how could anyone use such a thing for disinfection? Wouldn't that just make things more toxic?

"That's right. Pesticides can kill pests and diseases, so how could they not kill a few bacteria?"

Yan Jun's mother, however, acted as if it were perfectly normal, and didn't think she had done anything wrong.

The cause of the disease has finally been found.

It's surprising that a woman like Yan Jun's mother, who has lived in the city for many years, could be so ignorant.

In fact, Yan Jun's mother had been like this for quite some time. Her menstruation was irregular and she had lower abdominal distension, but she was embarrassed to go to the doctor for these reasons. Later, her condition became more and more serious, and she experienced nausea, vomiting, and abdominal pain, which is why she finally went to the hospital.

When she arrived at the hospital, she didn't mention any symptoms such as irregular menstruation. She only said that she felt nauseous, vomited, and had an upset stomach. In addition, the doctor's skill level was average, which led to the doctor's misdiagnosis.

"Auntie, you're healthy and only have some inflammation. If you were in poorer health, you might already be in the intensive care unit. You mustn't use pesticides for disinfection next time."

"Disinfection can be done by boiling in hot water or exposing to the sun, but it's best not to use other methods that you've heard about from others."

After giving her instructions, Xia Qiuran glanced at the time and quickly said goodbye to Yan Jun's family.

"Wait, Dr. Xia, we're so grateful to have troubled you again. You're truly our family's savior. Please keep this money."

Yan Jun said gratefully, and then took out ten yuan from his pocket and stuffed it into Xia Qiuran's hand.

"Comrade Yan, this is too much. Just give me one yuan."

Xia Qiuran immediately refused. She was here as a visiting doctor, so how could she charge more money just because she cured someone's illness? Besides, Yan Jun and Lu Zhenghan were good brothers. Although Lu Zhenghan disliked her now, he had helped her a lot before. She could charge more money from anyone but Yan Jun.

"Dr. Xia, please accept this. My son and my mother-in-law have both been indebted to you. This money is rightfully yours."

Wu Xiaona followed up with her advice.

"Comrade Yan, Comrade Wu, whether it's this time or the last time, I've only done what I was supposed to do. You really don't need to be so polite. I don't have change for this 10 yuan either. How about this, we'll settle it next time?"

Seeing that she couldn't refuse the two, Xia Qiuran simply turned around and left.

"Wait, Dr. Xia!"

"We agreed to settle the payment after the work was finished, how can you owe us money?"

Yan Jun immediately chased after her. Seeing that Xia Qiuran refused to accept the 10 yuan no matter what, he could only take out another yuan and thank her sincerely.

"Thank you very much, Dr. Xia."

Xia Qiuran accepted the one yuan directly, said a few polite words, and then quickly walked out.

This trip to the hospital has taken up a lot of time, and I don't know if I'll be late for class if I go back now.

Xia Qiuran borrowed a bicycle from a colleague and rode it quickly to the military base.

With only two minutes left before class started after arriving at the tutoring center, Xia Qiuran rushed to the classroom without even catching her breath.

There are rules in the military that no one is allowed to reserve a seat for someone else, no matter what they are doing; whoever arrives first gets priority in choosing a seat.

When Xia Qiuran arrived at the classroom, she found that all the front seats were already taken. The only empty seat was next to the disheveled soldier who had sat with Bai Yunyun last time. In order to hear the lecture better, Xia Qiuran didn't think much of it and went to sit down.

But then a handbag was thrown onto the chair.

"This is my seat," Bai Yunyun said as she walked over.

"Dr. Bai, you're not allowed to reserve seats in the classroom, and there's no such thing as assigned seats. What makes you think this seat is yours?" Xia Qiuran said angrily.

Bai Yunyun just chuckled and tilted her head back, looking completely unconcerned.

"Didn't you see my bag on the chair? I got here first, so the seat is mine."

Just then, Lu Zhenghan walked in with his textbook. Xia Qiuran didn't want to cause any trouble, so she turned around and sat down at the back.

Bai Yunyun sat down with a smug look on her face. She glanced at the slovenly soldier next to her out of the corner of her eye. Although she was disgusted, there was nothing she could do. After all, she had been late again because she had forgotten the time.

Meanwhile, the disheveled soldier next to him saw two of the most beautiful women in the unit vying to sit next to him, and subconsciously straightened his collar, which was already covered with black stains, and slowly curled up the corners of his mouth.

The saying "gold shines wherever it is" is indeed true. A man with inner beauty and substance like him can shine no matter how unkempt his appearance may be.
