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

The landlady looked at him with a half-smile and sneered, "Want to pay with your body? Not impossible. You're quite good-looking, and your ass is pretty perky. I'll introduce you to a brothel. The male customers there will definitely like your type. Sell your ass for one night, and you'll earn back the rent."

Chen Qing's face fell, and he said awkwardly with a smile, "Landlady, you misunderstood. What I meant was, could we only accept female guests... or you could just offset the rent directly?"

The landlady swayed her hips: "A female guest like me?"

"It's not impossible, then I'll reluctantly accept the loss..."

"Pah!" The landlady's face changed, and she spat at him. "You think you can make a move on me? If I were a widow, I might consider you, but I'm a respectable woman with a man, not Pan Jinlian. I'm giving you three days. If you can't pay the rent, pack your things and get out of here."

The landlady had given him an ultimatum. Chen Qing was at his wit's end when a notification popped up in his head: "Gynecological Master System binding in progress... System binding complete. This system can detect the patient's symptoms and provide solutions, but it is only effective for women."

Chen Qing instantly felt that his eyes could see the illness on her body.

The landlady has tiny nodules on her breasts, indicating stagnation of qi and blood along the meridians, and a cold uterus.

A few breaths later, a line of text appeared above her head: "Mrs. Hu, 31 years old, 165 cm tall, 105 catties. Long-term celibacy has led to liver qi stagnation, causing insomnia, restless sleep, frequent dreams and easy awakening, delayed menstruation with light flow, accompanied by chest and rib pain, cold hands and feet, and insufficient qi and blood. This is a gynecological condition caused by emotional distress. If the host can help treat this, a set of traditional Chinese massage techniques will be awarded."

Chen Qing's eyes lit up. The damn system had finally arrived, but this system left him speechless. The Gynecology Master System? He was a special agent, after all. What use could this be?

Chen Qing instantly had a way to deal with the landlady. He lowered his voice and said, "Landlady, have you been having trouble sleeping at night, feeling tightness in your chest, and having cold hands and feet lately?"

The landlady frowned. She had been tossing and turning at night lately, feeling tightness in her chest and cold hands and feet. He had been right.

However, this was, after all, a woman's private matter, and having Chen Qing say it like that still made her feel slightly embarrassed.

Seeing her like this, Chen Qing knew he was right. It wasn't really an illness, just a result of long-term lack of male pleasure.

If you can help cure the landlady's illness, you'll be rewarded with a set of massage techniques. Although they're not very useful, it's always good to have more skills.

Chen Qing immediately put on a serious expression: "Landlady, don't forget that I am a gynecologist. In a doctor's eyes, there are only patients. There is nothing to be embarrassed about. Don't be afraid to seek medical help. Your illness is caused by long-term emotional depression affecting your qi and blood. I will prescribe a prescription for you to regulate your body and you will be fine."

He certainly couldn't say it was because he had been living alone for years, or the landlady would probably turn on him immediately.

"Really?" The landlady asked, still somewhat skeptical.

At this point, the system provided a prescription, which was displayed above the landlady's head.

"Trust me, I'm a top student who graduated from the University of Michigan Medical School."

Chen Qing spouted nonsense, picked up a pen, and wrote down the prescription and dosage: Bupleurum, Curcuma, Angelica sinensis...

He handed over the prescription, adding, "Take one dose of this liver-soothing and qi-regulating medicine daily, decocted in water, for seven consecutive days. Before bed at night, soak your feet in water boiled with ginger and mugwort to warm the uterus and dispel cold; in the morning, brew a cup of rose tea to soothe the liver qi."

The landlady didn't know if the University of Michigan had a Traditional Chinese Medicine program, but she knew that anyone who had studied abroad must be very capable, so she believed most of what Chen Qing said.

The landlady took the prescription, her heart filled with joy, but she still asked cautiously, "This is free, right?"

Chen Qing waved his hand and said, "Landlady, what are you saying? It's naturally free for you. You can just go to the pharmacy to get the medicine. If it works well, please help me spread the word."

"Okay, if it works, I promise I'll get all my mahjong-playing girlfriends to come here for treatment."

"Thank you, landlady. I also have a set of the most popular American massage techniques, which can relax muscles and improve blood circulation. I can give you a massage for free."

"American massage? That must be good stuff!" The landlady didn't mention the rent anymore. After chatting for a bit, she happily took the prescription and left.

...............

At the Jinjiang Hotel, Wang Manchun slowly woke up. The quilt slipped off, revealing her perfect curves and the hickeys on her neck.

She was alone in the room; the warmth of their passionate night had long since dissipated. The man had left without saying goodbye.

The physical satisfaction had not yet faded, but a feeling of guilt towards her senior brother Minglou welled up in her heart.

She shook her head, shaking off the inexplicable unease, and stepped into the bathroom. The rising steam washed away the lingering pleasure from her body.

As she slowly got dressed, she noticed the black wallet hidden underneath her clothes.

She casually flipped it open; inside were only a few hundred French currency coins. She wouldn't care about such a small amount, but there was no need to throw it away—might as well take it.

After leaving the hotel, she arrived at the Paramount Ballroom, where she had been drinking heavily the previous night. Her car was parked not far from the entrance.

I drove to No. 76 and went to the office. The secretary brought me breakfast and several documents.

"Director, these documents require your signature."

While eating breakfast, she reviewed documents one by one, and one document filled her with immense joy.

"Minglou is hereby appointed as the Director of the Special Affairs Committee, and shall take up his post in Shanghai immediately."

A line of bold text made her heart pound: her senior brother was coming back! They could finally rekindle their romance!

But the next second, the face of that strange man from last night flashed into her mind, her smile froze on her face, and anxiety surged like a tide.

If her senior knew that she was no longer the innocent junior sister she once was, but a "promiscuous woman" who had a one-night stand with a stranger, would he still want her?

This hidden danger must be eliminated.

Murder to silence them!

The thought instantly took hold of her mind like a venomous snake.

She must always remain the pure and innocent junior sister in Minglou's heart, and any potential threat that might damage this image should be completely eliminated.

At the very least, I need to find out more about that man and see if he poses any threat to me.

She waved for her secretary to leave, picked up the phone, and found the Jinjiang Hotel's number in the phone book.

"This is number 76. Take me to the Jinjiang Hotel."

Once the call connected, she quickly obtained the information about the man from last night from the front desk register.

Registered name: Luo Yu, ID number: 9527, address: No. 32, Rue de Pai Dan, French Concession.

Wang Manchun immediately dialed the French Concession Police Station to verify the address, but the reply she received infuriated her: there was no No. 32 Rue Pétain; No. 32 had been burned to the ground in a fire ten years ago and had never been rebuilt; the document was fake!

She summoned her most capable investigator, Cui Mo, the head of the First Intelligence Division, and threw the black wallet in front of him.

"Is it possible to find the owner of this wallet?"

Cui Mo thought the investigation would focus on the Red Party, but the Military Unity Army had just been completely wiped out a month ago, so the only possibility was an investigation into the Red Party.

He carefully examined the wallet, then picked it up and smelled it.

"There's a faint smell of disinfectant on it, the kind of smell that people who work in pharmacies or hospitals all year round would pick up."

Wang Manchun then remembered that the man from last night did indeed have a faint smell of disinfectant; she had drunk too much at the time and had mistaken it for some kind of perfume.

"Take men and search all pharmacies, hospitals, and clinics in the French Concession. Find a man in his twenties, around 1.8 meters tall, with a strong build, short hair parted to the side, a high nose, thin lips, and a barely noticeable mole on his left eyelid. Report to me immediately if anyone matches this description!"

"Yes, Chief!" The subordinate didn't dare to be negligent and quickly turned and left.

Just then, there was a knock on the door, and a man with a cane pushed the door open and came in.

It was Liang Zhongchun, the team leader. He closed the door and said mysteriously, "Do you know what happened last night?"

Wang Manchun frowned and asked, "What happened?"

"Last night, someone from the Military Police Headquarters secretly photographed the deployment map and troop configuration of the Central China Expeditionary Army, as well as a top-secret document. Chief Nantian of the Special Higher Police Section found that it belonged to Wang Shengqian, the confidential secretary of the Military Police Headquarters."

"Has the person been caught?"

Liang Zhongchun shook his head: "No, Wang Shen ran away with film reels containing troop deployment maps and top-secret documents. My men and the Special Higher Police are chasing after him."
