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

The warm afternoon sun shone through the glass window, and Mrs. Liang slowly woke up, stretched, and the stiffness and soreness in her waist had almost disappeared. She felt much lighter and her complexion had improved.

This Dr. Chen is indeed quite skilled.

"Dr. Chen, your American massage is even more authentic than the massage therapists at the massage parlors. I feel much more relaxed, and my back doesn't hurt anymore."

Chen Qing smiled gently: "Mrs. Liang, you're too kind. You have lumbar muscle strain, which needs to be treated slowly. Come once a week, and seven times a week will complete one course of treatment. I guarantee your condition will be cured completely."

"Then I'll be there on time next week!" Mrs. Liang said readily, taking out a hundred-yuan bill from her bag and handing it to him.

"Mrs. Liang, this is too much."

"Keep it, keep it. Your skills are worth the price. I'll introduce a few of my sisters to come and experience it another day." Mrs. Liang said, pressing his hands down with both of them. The hunger in her eyes could no longer be concealed, and her words were quite ambiguous.

It seems Mrs. Liang has other ideas about me.

The landlady also advised, "Xiao Chen, you should keep it. I'm going shopping with Mrs. Liang."

"Thank you, Mrs. Liang." Chen Qing put the money away, saw the two to the door, and the landlady hailed a rickshaw, which the two then drove off in.

One hundred French francs could be exchanged for more than thirty silver dollars. Half of that had to be given to the landlady, and another fifteen dollars for rent. There was hardly anything left for myself.

However, it solved Chen Qing's immediate problem. If Mrs. Liang comes again next time, she'll make a profit.

Chen Qing happily put the money away, and a notification popped into his head: "Divine Acupuncture Techniques have been credited to your account."

A massive flow of information surged in like a tidal wave, instantly filling his mind.

A crystal-clear diagram of the human body's meridians unfolds in my mind. The twelve regular meridians and the eight extraordinary meridians are like luminous rivers, crisscrossing each other. The location, depth, and indications of each acupoint are clearly marked. I can even "see" the trajectory of Qi and blood flowing through the meridians.

The different shapes of filiform needles, three-edged needles, and dermal needles, the angle and depth of needle insertion, the force of twisting and lifting, the subtle differences between tonifying and reducing methods, and the operating principles of warm needling and electroacupuncture—each and every detail was explained in such detail that it was as if he had personally studied them for decades.

Even more remarkably, countless memories of acupuncture techniques seemed etched into his muscles. A strange sense of familiarity arose in his fingertips, as if he had held, inserted, and manipulated the needles hundreds of times. Whether it was the combination of Shenshu and Dachangshu points for treating lower back pain, or the application of Ashi points for treating strain, he knew them by heart. He could even clearly sense that if a patient came at this moment, he could accurately locate the acupoints with a simple gesture, moving the needles with lightning speed and without the slightest error.

Chen Qing stood there, stunned for the time it takes to drink half a cup of tea. His eyes gradually shifted from initial bewilderment to shock, and then to undisguised ecstasy.

Now I'm a traditional Chinese medicine doctor myself, although I specialize in gynecological diseases.

Chen Qing went to the pharmacy and spent two silver dollars to buy a set of silver needles. With acupuncture, he could cure some difficult and complicated diseases.

He went to the pharmacy, picked out a set of high-quality silver needles, all sizes available, and the shopkeeper asked for two silver dollars. He didn't haggle, paid directly, and put the silver needles away.

According to the original owner's memory, there was a dead mailbox in Zhongshan Park not far away, hidden under the stone bench in the park.

The Military Intelligence Bureau had an undercover agent codenamed Squirrel in the 76th Division. He would always hide intelligence in a dead mailbox, and the two sides never met.

The original owner received the intelligence and sent it to headquarters via the radio at the liaison station. Since it was on the way, he decided to check if there was any intelligence in the dead mailbox.

The afternoon sun was shining brightly. He bought a newspaper, turned into Zhongshan Park, and went straight to that quiet bench.

But then he saw a man in his thirties sitting in the chair, wearing a long gown and with a gloomy expression.

There was a wheelchair parked nearby, and an elderly woman with gray hair was sitting in it. Her mouth was crooked, her eyes were slanted, her left hand was hanging limply, and her eyes were cloudy. It was obvious that she had suffered from the aftereffects of hemiplegia.

Chen Qing couldn't directly touch the dead mailbox, so he could only wait for the person to leave. He then sat down in a corner of the bench, pretending to read the newspaper, but his gaze fell on the old lady. The system unconsciously scanned the old lady's symptoms.

The pathological mechanism and symptomatic treatment of hemiplegia caused by cerebral infarction instantly came to mind from the acupuncture knowledge he had just acquired, and he felt more confident.

Cerebral infarction is very common in later generations, but in the Republic of China era, when people couldn't even get enough to eat, only the very wealthy could afford to get this disease.

Chen Qing put down the newspaper and said gently, "Sir, judging from the old lady's symptoms, it seems to be hemiplegia caused by a cerebral infarction."

The man turned his head, a strange look flashing in his eyes. He then sighed, nodded, and said, "Yes, my mother has been sick for half a year. We've been to all the major hospitals in Shanghai, spent a lot of money, and taken a lot of medicine, but there's been no improvement at all. She can't even speak properly now."

"Why not try traditional Chinese medicine acupuncture?" Chen Qing immediately got itchy and pressed on, "For the old lady's illness, acupuncture to regulate the meridians and unblock the qi and blood might have a different effect."

"Impossible." The man shook his head without hesitation. "Western medicine instruments can't find a cure, so how could a few needles from traditional Chinese medicine work? Besides, I've already tried an old Chinese medicine doctor before, and after more than a month of treatment, there was no improvement whatsoever."

Chen Qing said confidently, "Sir, you may not know this, but acupuncture emphasizes diagnosis and treatment, and requires exquisite techniques. I happen to have some experience in treating hemiplegia caused by cerebral infarction, and I happen to have a family-inherited acupuncture technique. Why don't you let me try it?"

The man frowned, clearly still unconvinced, and was about to refuse when the old woman in the wheelchair suddenly stammered, "Ah...ah..." She raised her left hand with difficulty and pointed tremblingly at Chen Qing, her eyes revealing a hint of urgency, as if she was gesturing for him to give it a try.

"Mom?" The man paused, then leaned closer to the old woman. "You mean, let this gentleman give it a try?"

The old woman nodded with difficulty, her mouth crooked, but she still tried to force out a vague expression, as if she were pleading.

At this moment, several people who were strolling around also gathered around to watch the excitement.

An old man said, "Young man, I see you're still young. You've just learned acupuncture and want to practice, but don't be reckless. What if you hurt yourself?"

Another old lady said, "It's already like this, we might as well try anything, it can't get any worse."

Everyone chimed in with their opinions, and after a moment's hesitation, the man said, "Since my mother insists on trying, then you...you can give it a try. But let me make this clear beforehand: you'd better be careful and don't hurt my mother."

Chen Qing said no more, took out the set of silver needles, and used the alcohol swabs he had just bought. Acupuncture requires disinfection, and disinfection is of utmost importance and cannot be taken lightly.

He gestured for the man to roll up the old lady's sleeves slightly, exposing her left arm and neck area, and then asked him to adjust the wheelchair angle to make the old lady's sitting posture more stable and improve blood circulation.

Chen Qing focused his mind and instantly came to mind a plan of acupoints for treating hemiplegia caused by cerebral infarction: Jianyu, Quchi, Shousanli, Hegu, Huantiao, Yanglingquan... The location of each acupoint was clear as if it were engraved.

A faint sense of energy lingered around his fingertips as he raised his hand and precisely placed it on the old lady's Jianyu acupoint. He gently pressed with his thumb to confirm the acupoint was correct, then held the silver needle and quickly inserted it using the "single-hand needle insertion method," with the angle and depth being perfectly accurate.

The moment the silver needle entered the acupoint, the old lady frowned slightly, as if she felt a slight soreness, but it was gone in an instant.

Chen Qing twisted the needle with his fingertips, using the "twisting and tonifying method". The force was even and the rhythm was steady. The needle was seen to rotate gently in the acupoint. The air flow, which was invisible to the naked eye, flowed into the meridian along the needle and cleared the blocked blood and qi.

His movements were fluid and graceful; in a short time, he had inserted several silver needles into the designated acupoints.

While observing the old lady's expression, Chen Qing adjusted the depth and technique of the needle from time to time, sometimes lifting and inserting, sometimes twisting, with a focused expression.

Finally, the acupuncture was finished, and he removed the last silver needle.

"Mom, how are you feeling? Does it hurt?" the man asked anxiously.

The old woman blinked, her lips moved, and her face returned to normal. She raised her left hand and clearly uttered two words: "It... doesn't hurt."

"Mom!" the man exclaimed, his voice trembling, "You can speak!"

The onlookers, who had initially been just curious onlookers, could no longer contain themselves and erupted in a deafening gasp.

"My God! This is amazing! He was just lying there with his mouth and eyes crooked, and now he's all better?"

"Absolutely! I just saw that the old lady couldn't even lift her arm, but now she can move it freely. This acupuncture technique is simply miraculous!"

"This doctor is so young, yet so skilled; he's even more capable than the specialists at those big hospitals!"
