Siheyuan: How dare I mess with a man who is an expert in men's health?

Cao Anping was bored and finally waited until the end of get off work. Doctor Song came to his clinic as promised and invited him to go back and read medical books together.

He smiled, tidied up the table briefly, and walked out with empty hands.

Doctor Song looked as if he wanted to say something but hesitated, his expression a little unnatural.

Cao Anping saw this and asked in confusion: "Come on, Doctor Song, is there any problem?"

Doctor Song forced a smile and wanted to ask: "Aren't you bringing your own medical books? If you like my books, you can exchange them. This is a bit like getting something for nothing."

But in the end, he could only squeeze out one sentence: "It's okay, let's go."

Cao Anping actually knew everything in his mind, but he couldn't possibly show the 'Thirteen Needles of Ghosts and Gods' to this guy. He was 99% sure that there was something wrong with this guy. If such a good thing accidentally flowed abroad, it would be a sin.

He went there to investigate and was always ready to send the other party in. Naturally, he would not care about the other party's feelings and of course he would shamelessly take advantage of the situation for free.

When leaving the clinic, several interns looked at Cao Anping and his companion's backs curiously. They didn't expect that Dr. Song, who was usually taciturn, had such a good relationship with Dr. Cao. Could this be what it means when heroes appreciate each other? Only people with ability can have something to talk about?

The two men, each riding a bicycle, rode out of the steel mill quickly and headed in the opposite direction of Nanluoguxiang.

Cao Anping thought to himself: "Perhaps Dr. Song has chosen this address carefully, otherwise it is too close to Nanluoguxiang. If he accidentally runs into the deaf old lady, he might be exposed. But I have to admire his courage. He is lurking right under our noses."

After riding for nearly twenty minutes, they arrived at a large courtyard, and they got off the bike and pushed it into the yard.

The residents of this courtyard are even more densely populated than those of No. 95 Nanluoguxiang. Most people move their stoves under the eaves. When the neighbors see Dr. Song, they greet him warmly and it seems that they have a good relationship with him.

However, Dr. Song just forced a smile to respond to everyone, and the neighbors didn't think he was being rude. It seemed that they were used to it.

After entering the courtyard, Cao Anping became extremely alert. Not only did he start the space exploration, he also kept observing everyone, but he didn't find anything unusual.

He sighed in his heart: "He is really a great man hiding in the city. This guy has been lurking for at least ten years and has long been deeply rooted. I guess his only flaw is that the deaf old lady kept a photo of him out of nostalgia."

When they arrived at a room in the backyard, Dr. Song opened the door and said with a smile, "This is my home. Welcome Dr. Cao to visit me.

But my house is a little messy since few people come to visit. I hope Dr. Cao doesn’t mind.”

Cao Anping felt the space probe and showed a strange look. He walked into the house and replied with a smile: "How could it be? I am bothering you."

After Dr. Song entered the house, he said, "Please sit anywhere," and started fiddling with the stove. After all, he was the only one at home, and the house was a bit cold when the stove was turned off during the day.

Cao Anping looked around the room. It did look messy, like a room without a hostess. But there was a photo frame on the cabinet, and the photo showed a pretty woman.

He didn't consider the other person's feelings at all, like a young man with no emotional intelligence, and asked directly:

"Doctor Song, this is your wife, right? She looks well-educated and well-mannered. You must be very happy."

Doctor Song's hand trembled noticeably as he lit the fire. He turned to look at the photo on the cabinet, then sighed and replied, "Yes, it's a pity that she died early due to illness."

At this time, everyone should have said a few words of comfort, but Cao Anping was not a man. He then asked:

"It's a pity. Doctor Song, where are your children? Are they about to graduate and start working?"

Doctor Song lowered his head and a trace of gloom flashed across his face, and then doubt emerged. He was a little confused whether Doctor Cao really spoke without restraint, or whether the other party saw through something and deliberately pointed at him?

However, he could only suppress his suspicion and replied with a wry smile: "Hey! No children, I have some health problems..."

Cao Anping was shocked: "Good fellow! Doctor Song is really honest, unlike some people."

Yi Zhonghai! I'm talking about you. Learn from Dr. Song and be brave enough to admit that you are not good enough! You are a real warrior!'

After Cao Anping finished complaining in his heart, he sighed: "Hey! Doctor Song, you didn't meet me earlier. You don't know my nickname is 'Magic Hand of Men'? If..."

Doctor Song's scalp was numb. He didn't expect Doctor Cao to be such a chatterbox. He didn't even light the stove and quickly interrupted:

"Those things are in the past, let's not talk about them anymore... Let me get you the medical book first! So you don't get bored!"

Cao Anping curled his lips, wanting to see if the spy who was hiding so deeply could be breached by his eloquent tongue.

The other party went into the inner room, and he began to use space to explore the inside and outside of the house, scanning the ground and the beams inch by inch.

However, in the end, they only discovered one anomaly that they had discovered outside the door at the beginning: there was actually a basement right below the house.

There weren't many things in the basement, and it was impossible to tell what they were just by looking at the outline, but one of the things caught Cao Anping's attention.

That thing looked a lot like a radio, and it had two antenna-like outlines, but which normal person would put a radio in the basement, so he doubted that it was something like a radio station.

Cao Anping did not move anything for fear of alerting the enemy. He could not kill the other party directly for fear of causing trouble. It seemed that he had no choice but to report it.

At this time, Doctor Song came out from the inner room, holding a dozen books carefully in his hands.

He put the book on the table and said with a smile, "Doctor Cao, please take your time reading. I'll cook first and we'll have dinner together later."

Cao Anping did not refuse. He picked up the book and started reading. However, he felt overwhelmed after reading it for a while. Half of these medical books were ancient books written in traditional Chinese characters. He had no desire to read them and no need to stay any longer.

So he flipped through them casually and said, "Doctor Song, these books of yours are very valuable. You exchanged so many medical books for my one family medical book. Aren't you losing out a bit?"

Doctor Song's eyes lit up, and he said nonchalantly, "Medical books are only valuable if someone studies them. You can read them. So, Doctor Cao, are you willing to exchange with me?"

Cao Anping was speechless. Of course you don’t care. I’m afraid you have already made a copy and sent it away, or the more precious original has been sent overseas.

He suppressed his desire to complain and replied, "You are right. Medical books are only valuable if someone learns them. I agree to exchange studies.

But I didn't bring it today, so I'll bring the medical book to the steel mill tomorrow, and you can read it while you're at work."

Doctor Song replied happily: "Okay, then I'll trouble Doctor Cao."

Cao Anping asked embarrassedly: "I love studying so much that I don't even want to eat after reading the medical book. Do you think I can take the book home to read?"

Doctor Song said readily, "Of course, but Doctor Cao, you should eat before you leave."

Cao Anping insisted, and said calmly: "No, I can't wait to concentrate on my studies." After that, he picked up the book and stood up to leave.

Dr. Song did not try to persuade him to stay, and said with a smile that he did not expect Dr. Cao to be such an impatient person.

Before leaving, Cao Anping thought for a moment, and used the space to silently place the several pieces of information he had stolen from the deaf old lady, as well as the photo, at the bottom layer of the closet in the inner room before he strode away.

Doctor Song looked at Cao Anping's back, the smile on his face disappeared, and a thoughtful expression appeared. As a cautious undercover agent, it was impossible for him not to notice some abnormalities in Cao Anping.

But he didn't know Cao Anping at all, so he wasn't sure whether his abnormality meant something or whether his behavior was simply due to his personality.

After Cao Anping left the yard, he felt happy and got more than ten medical books for free.

As for the promise to show Doctor Song the 'Thirteen Needles of the Ghosts and Gods' tomorrow, he didn't take it to heart at all. Since the other party had been arrested, the debt would naturally be settled.
