If you had to choose an identity to go undercover, you'd choose a gynecologist.

"Dr. Chen, do you remember me?"

"I remember, how could I not remember?" Chen Qing quickly asked her to sit down.

"My name is Xing'er. I... I went to get checked and found out I have MD. When the madam found out, she kicked me out of the brothel that very day... I went to a foreign hospital, but the foreign doctors just shook their heads and said that this disease is incurable. The treatment requires injecting some kind of arsenic compound. Even if it is cured, I will suffer from arsenic poisoning, my whole body will be covered in sores, and I won't live for more than a few years. Moreover, the child I give birth to will not have limbs and will look like a seal."

Chen Qing immediately understood that in this era, MD was an incurable disease.

Arsenic compound drugs commonly used to treat MD not only fail to cure the disease, but can also cause arsenic poisoning in patients, leading to a faster death.

Chen Qing said, "It can be cured, but I need to examine the symptoms first."

Chen Qing led Xing'er to the inner room, had her lie on the medical bed, and carefully examined her.

Then he picked up a pen and wrote down the prescription as prompted by the system: licorice, honeysuckle, coptis...

I paused when writing about the last dose of medicine: penicillin.

He inwardly cursed his carelessness. Penicillin also has a foreign name, penicillin. Penicillin was only produced in 1942. Where could he get it now?

He just promised to cure it, but now he only has the prescription and no penicillin. Isn't that just empty talk?

Seeing his solemn expression, Xing'er's newly ignited hope sank again: "Dr. Chen, is it... is it that this medicine is hard to find?"

Chen Qing didn't respond. His gaze fell on the system interface in his mind. Just as he was thinking about what to do, the interface suddenly refreshed, and lines of information about penicillin manufacturing methods suddenly appeared: from screening Penicillium strains and preparing potato culture medium, to temperature and humidity control and gradient purification process, the steps were so detailed that even the sterilization details of the petri dishes were clearly marked.

Immediately afterwards, a mission notification popped up: Penicillin successfully produced, curing MD. Reward: One virus.

“…………”

Chen Qing's lips twitched, speechless.

He had expected the system to reward him with rare medicinal herbs, advanced equipment, or at the very least, skill points to improve his medical skills. Instead, it turned out to be a virus.

He shook his head. This Gynecology Master System was truly bizarre. But when his gaze swept over Xing'er's face, which was filled with despair, he hesitated again.

What you say big, you must always keep.

He pushed the prescription he had written in front of her: "The penicillin in this prescription is not currently produced domestically and cannot be bought on the market."

Xing'er's face turned pale instantly, and tears welled up again, but Chen Qing interrupted her with his next words: "However, it's not entirely hopeless. This penicillin is extracted from a type of mold, and I can cultivate the strain myself and then purify the drug step by step. It's just that the process is complicated and will take at least half a month, and every step must be done correctly. If there is the slightest mistake, all the previous efforts will be wasted."

Xing'er listened in a daze, then knelt down with a thud: "Dr. Chen, as long as you can save me, I'm willing to do anything! Whatever you want me to do, I'll do it! I'll repay you by working like a cow or a horse, even if... even if there's only a sliver of hope, I don't want to die like this."

Chen Qing looked at the light that had rekindled in her eyes and felt a mix of emotions.

He handed the prescription to Xing'er: "Go and get the medicine first, then go back and decoct it to stabilize your condition. Come back every three days so I can examine you. Once I've cultured the penicillin, we'll officially begin treatment."

The "virus reward" flashed through his mind again, and he couldn't help but sigh inwardly. Whatever kind of virus it is, he'd better get rid of the illness in front of him first.

After all, doctors have a compassionate heart; they can't just stand by and watch a vibrant life slowly wither away.

Chen Qing went to a general store and bought glassware, which she repeatedly scrubbed, washed, and disinfected.

After draining the water, three layers of sterilized gauze were laid at the bottom of the basin. The cleaned potatoes were then cut into half-centimeter-thick slices and evenly arranged on the gauze to begin cultivating penicillin bacteria.

Oranges are the key carriers of the microbial culture. He selected oranges with a natural white bloom on their peels from the market, carefully wiped the peels with alcohol wipes, and waited for the alcohol to evaporate completely before using a sterile blade to make a small incision at the stem end of the orange, gently squeezing out a plump segment of pulp, and evenly spreading its juice on the surface of the potato slices.

Everything was ready, and the items were placed in the basement, the ideal place to maintain just the right humidity and temperature.

Another busy day has passed, and there weren't many customers in the afternoon. Just as Chen Qing was about to close the door, the landlady returned.

She walked straight in, smiling, and held out her hand: "Xiao Chen, you earned two hundred yuan today, one hundred of which is mine."

Chen Qing took out a hundred yuan and gave it to her. The landlady happily accepted it, but showed no intention of leaving.

"Landlady, is there anything else?"

She said somewhat shyly in a low voice, "Xiao Chen, the American massages you gave Mrs. Fang and Mrs. Wang were raved about, saying they were even more comfortable than having sex with a man. My old back has been sore lately, and I'd like to try it too, but you're not allowed to mention money to me."

Chen Qing smiled and said, "You're joking. We're neighbors, talking about money would make us feel distant. Please come in, I just finished tidying up, it's nice and quiet now."

The landlady went into the inner room, and Chen Qing locked the door from the inside, just in case someone came in and saw what was going on.

Upon entering the inner room, the landlady was already lying on the medical bed. Chen Qing said, "Why don't you take off your coat? It's hard to gauge the pressure through your clothes."

The landlady took off her coat, revealing purple underwear that subtly accentuated her curvaceous figure. Everyone says purple has a lot of charm, tsk tsk!

Chen Qing placed his hands on her shoulders and first helped her relax them. As the landlady's shoulders and back gradually relaxed, Chen Qing began to move his hands down, pressing and kneading them with just the right amount of force.

The landlady initially chatted quietly about everyday things, but after a while, all that remained was a satisfied sigh.

The atmosphere was somewhat ambiguous. Chen Qing massaged her legs and feet, and she felt like her nose was about to bleed.

After a full-body massage that lasted a full hour, the landlady had fallen soundly asleep.

Looking at the landlady's graceful figure, Chen Qing took a deep breath, rushed to the toilet, washed his face with water, and forced himself to wake up.

Which cadre could withstand such a test? Fortunately, I was determined and did not make any mistakes.

She couldn't afford to make a mistake; she was a married woman. If the landlord came back, he'd tear her apart.

He sat at the table, absentmindedly flipping through a copy of Water Margin, reading from Pan Jinlian's affair to Wu Song's fight with Ximen Qing at the Lion Tower.

I sat there until midnight when the landlady finally woke up and came out of the inner room with a flushed face.

"Xiao Chen, your American massage is so comfortable! I've wasted all these years. I'm going home now, I'll come back for another massage another day."

Chen Qing saw her out, breathed a long sigh of relief, and quickly went upstairs to sleep.
