Before leaving, Zheng Libing said he would gather footage of the individuals’ daily gaits as soon as possible and would return to have Yan Feifan identify them.

After the police officer left, Yan Feifan quickly opened the thin envelope and took out a cashier’s check.

The first digit was a 1, followed by five zeros.

One hundred thousand!

Yan Feifan was quite satisfied with this number.

It was a windfall, after all.

Recently, Yan Feifan had clearly noticed a change in his sister. Perhaps it was because the pressure was off, or maybe it was a rebound from being too suppressed before. Her desire to spend was growing, and her spending habits were becoming more upscale.

‘With this extra one hundred thousand in income, plus our family’s savings,’ Yan Feifan thought, ‘we most likely won’t have any financial trouble for the next year or two.’

‘As for what happens after a year or two… my sister should be married by then, right?’

Yan Feifan suddenly noticed Mr. Wang watching him with a wide smile. He hurriedly put the check away and said with a straight face, “Mr. Wang, shall we continue with your lecture?”

Wang Chuan smiled and said, “It’s twenty minutes to nine. Let’s call it a day.”

“Oh, by the way, Yanyan has invited your sister and Xiaoyu to Phoenix Tail Mountain again.”

“I have to pick them up and take them home in a bit.”

Yan Feifan let out a soft “Oh” and handed the envelope over.

“Mr. Wang, could you please give this check to my sister then? She handles all our family’s finances.”

He then changed the subject. “Mr. Wang, I’m planning to have Yu Suye join the pro-bono plastic surgery project for the orphanage children.”

“The surgical fees will be paid from those two charitable donations…”

Yan Feifan explained his idea, adding, “Once Mr. Xiao reports on it, we might receive more donations, allowing the project to continue indefinitely.”

Wang Chuan grunted in acknowledgment. “You can decide for yourself how to use that charitable donation.”

“But just to keep the project going?”

Wang Chuan sighed. “Feifan, to be honest, if I got involved and reached out to a few big bosses and a few big celebrities, I could easily raise several million, maybe even tens of millions.”

“However…”

After a pause, Wang Chuan said quietly, “The more alms you give, the more beggars you attract.”

“And the orphanage might not appreciate this kind of high-profile publicity…”

“Really?” Yan Feifan didn’t quite understand.

Wang Chuan didn’t explain, only saying vaguely, “Feifan, you don’t need to know the reasons why.”

“Just follow your heart and do what you think is right…”

Zheng Libing’s next invitation came quite quickly.

Around four in the afternoon, Yan Feifan was brought to an office in the district’s criminal investigation department to watch several video clips on a computer screen.

Yan Feifan noticed that the face of the man in the first video was pixelated.

“Mr. Yan, you saw their headshots this morning. By covering their faces, we don’t have to worry about their appearance influencing your judgment.”

Yan Feifan thought Zheng Libing’s explanation made some sense, so he continued watching the videos one by one.

As he watched, he carefully compared their gaits to the one he had seen in the video that morning.

A few seconds after the fifth video started playing, Yan Feifan blurted out, “That’s him!”

Zheng Libing asked doubtfully, “Mr. Yan, are you sure?”

Although annoyed by the other man’s distrust, Yan Feifan patiently explained, “Mr. Zheng, I know we have to be careful with something like this. We can’t wrong an innocent person.”

“But please, trust my professional expertise. This is absolutely the guy from this morning’s video.”

Zheng Libing looked at the man in the paused video, hesitated, and said, “Mr. Yan, it’s not that I don’t trust your expertise.”

“To be frank, we added videos of several other people to this set to act as confounders.”

“And this man is one of them.”

“This person… had already been cleared of suspicion in our preliminary investigation.”

Yan Feifan stood up, clearly displeased. “After all that, you still don’t trust my professional judgment.”

“Why don’t you question whether your own preliminary investigation was flawed or if you were misled?”

At this, Yan Feifan proposed, “How about this, Mr. Zheng? Go film some of your colleagues walking, and let’s see if I can identify each and every one of them.”

Zheng Libing slowly nodded. “That is indeed a good suggestion.”

He then apologized with a smile. “Mr. Yan, it’s not that we don’t believe you. But with a skill like yours, we need to see it to believe it.”

Yan Feifan said impatiently, “Mr. Zheng, I understand your concerns. You put more faith in so-called technical analysis and verification.”

“Hurry up and film the test videos. My time is valuable too…”

After Zheng Libing left, Yan Feifan waited boredly in the office for over ten minutes before a female officer in her twenties pushed the door open and came in.

“Mr. Yan, one of our colleagues isn’t feeling well. Could you take a look at her?”

He had nothing else to do, so Yan Feifan naturally agreed.

Soon, a pale-faced female officer in her thirties was helped into the room by the younger officer and sat down in a chair.

Seeing how weak she looked, Yan Feifan asked, puzzled, “Why didn’t you just take her to the hospital?”

The young officer explained, “We tried, but Mrs. Na insisted on working. She said it’s just menstrual cramps.”

The officer called Mrs. Na forced a smile. “Mr. Yan, I have a chronic problem with menstrual cramps. I’ve been busy with a case these past few days and haven’t been resting well, which just made it worse.”

The younger officer said anxiously, “Mrs. Na, when you got up to get some water just now, your legs gave out and you fell.”

“Weakness in the legs?” Yan Feifan asked, on high alert.

Mrs. Na hesitated for a moment, then nodded. “When I stood up just now, my legs suddenly felt weak. Even now, they still feel weak and numb.”

Yan Feifan checked her carotid artery. Her heart rate was 97, and her pulse was reasonably strong. He then felt Mrs. Na’s legs but found no edema.

With reduced muscle strength in the lower limbs, the first thing to rule out was a stroke, such as a cerebral hemorrhage or cerebral infarction.

Yan Feifan saw that Mrs. Na was currently lucid and asked her a few questions, to which she gave coherent answers.

Furthermore, when he checked her, Mrs. Na’s tongue protruded centrally, her nasolabial folds were symmetrical, and there was no drooping at the corners of her mouth. There wasn’t much evidence to support a cerebrovascular accident.

Yan Feifan asked again, “Besides the menstrual cramps and weakness in your legs, are there any other abnormal symptoms or discomfort?”

Mrs. Na thought for a moment, then said hesitantly, “I’ve been drinking a lot of hot water since this morning, but I haven’t been to the bathroom at all.”

“Mr. Yan, does that count as abnormal?”

Yan Feifan inquired further, “How much water have you had, specifically?”

“And how long has it been since you went to the bathroom?”

Seeing Yan Feifan’s serious expression, Mrs. Na couldn’t help but grow nervous.

She recalled, “To ease the cramps, I’ve been drinking hot water one cup after another. Each cup is one or two hundred milliliters, so I must have had more than ten cups.”

“As for going to the bathroom, I haven’t been since I got to the station at eight this morning!”

Mrs. Na added, “I don’t even feel the urge to urinate right now!”

She had drunk at least two thousand milliliters of water, hadn’t been to the bathroom for eight hours, and felt no urge to urinate.

These were not good signs at all.

‘Weak legs, no urination, and menstrual cramps?’

A sudden chill went through Yan Feifan. ‘What if this “intensified menstrual pain” isn’t actually caused by menstrual cramps at all?’

Combining these symptoms, one possibility immediately came to his mind.

Aortic dissection.

If an aortic dissection tears all the way down and affects the renal arteries, the kidneys will become ischemic, leading to anuria.

If it affects the mesenteric artery, it will cause intestinal ischemia and abdominal pain.

If the dissection affects the blood vessels of both lower limbs, the resulting ischemia would also cause weakness and numbness in the legs.

Thinking of this possibility, Yan Feifan had Mrs. Na hold out both her hands.

He pressed his fingers to both her wrists, carefully feeling for her pulse.

Seeing this, the young officer asked curiously, “Mr. Yan, are you also a practitioner of traditional Chinese medicine? Can you read pulses?”

Yan Feifan didn’t respond. He closed his eyes, focused on feeling the pulses in Mrs. Na’s wrists, then withdrew his hands.

He said with extreme seriousness, “I’m not a TCM practitioner, and I wasn’t reading your pulse just now. I was feeling the pulse pressure in both of your arms.”

“There is a significant difference in blood pressure between your upper limbs.”

“This points to a strong possibility: aortic dissection.”

“You must get to the hospital immediately for a contrast-enhanced CT of your chest, abdomen, and pelvis…”
