The eyes of the three women immediately lit up, especially Qian Shanxue sitting next to Shen Qiang. Her beautiful eyes sparkled as she looked at Shen Qiang, shockingly saying, "Shen Qiang, you are amazing."

At the same time, Ye Xiaolei in the back row also enchantingly said, "Awesome, if that's the case, it explains why so many people were investigated back then, yet the real criminal was never found."

Just then, Ali laughed and said, "Yes, if it weren't for Shen Qiang bringing it up, who would think that everyone has fingerprints, that such a common sense issue would have errors? However, even if that veteran officer's intuition was right, this criminal is indeed a patient with fingerprint anomaly, it doesn't necessarily mean he is still alive now."

This statement immediately made everyone collect their smiles, and their expressions became serious.

Ye Xiaolei sighed and said, "Perhaps, the veteran officer's intuition was all correct. It's possible this killer is still alive, just like the officer said, still at large, so I think we need to get to the bottom of this."

Qian Shanxue frowned slightly and said, "Things aren't that simple. After so many years, even if we know he's a patient with fingerprint anomaly, we still have no leads to follow. After all, this is a Provincial City with millions of people; we can't search them one by one."

Upon hearing this, Ali sighed and said, "But at least there's hope of catching this guy, isn't there? Even if he's dead, we have to find him and confirm he's deceased; otherwise, who can assure us he won't commit crimes again? Who will bring justice to those who died?"

The atmosphere in the car became oppressive with Ali's words.

Just then, Shen Qiang raised his eyebrows and smiled, "Cheer up. How can you face challenges with such a mental state? The characteristics of fingerprint anomaly don't affect daily life. Ordinary contact won't make it detectable, but at the same time, because it's an illness, there will be certain pathological signs."

Ye Xiaolei's beautiful eyes lit up as she said, "Pathological signs? Are you saying his appearance might differ from ordinary people?"

"The differences aren't very obvious, but they can be traced, because generally speaking, people without fingerprints usually have thickened palms and soles. Their teeth, hair, and skin developments are irregular, resulting in uneven pigmentation, for example, their hair is often sparse, nails are wrinkly and brittle, and there are spots on the skin," Shen Qiang raised his eyebrows and said.

Qian Shanxue's beautiful eyes sparkled and said, "Then combining these conditions, we basically understand this criminal's situation. According to the psychological profile created by the police, his personality traits tend to be introverted, depressed, cold, unsociable, withdrawn, extremely patient in doing things, and possess a very obvious dual personality, with a strong tendency towards secrecy."

"Now adding in an age of over fifty with no fingerprints, male, sparse hair or bald, spots on the skin, irregular teeth development…"

"It's useless." Ali said, "These details, although they bring the image of this killer vividly before our eyes, relying solely on this to catch him is almost impossible."

Qian Shanxue was stunned.

Ye Xiaolei sighed and said, "Yes, elderly people with balding, hair loss, age spots are very common, and those who match these traits in the Provincial City alone might number tens of thousands. As for irregular teeth development, current dentists are very skilled. If you're willing to spend money, you can have neat and white teeth, so simply having these traits isn't enough. We still can't be sure to capture him."

"Let's start with cultivation practitioners first," Shen Qiang said, and then he made a phone call, "Find a male cultivation practitioner over the age of fifty-five, possibly wearing a wig, false teeth, with age spots on the skin, cold personality, unsociable, extremely patient in doing things."

After hanging up the phone, Shen Qiang turned his head and saw the three women were staring at him.

Shen Qiang couldn't help but smile and said, "Why are you staring at me?"

Ye Xiaolei's eyes sparkled and said, "If he is indeed a cultivation practitioner and stays here, then your informants will definitely find him."

Ali also confidently said, "Yes, didn't we catch that fat guy in the same way before?"

Qian Shanxue said, feeling tense, "If he is a cultivation practitioner, then he can't escape the monitoring of Heshenghe; we might be able to catch him soon."

Just at that moment, Shen Qiang's phone rang.

"Boss, we've checked the cultivators living in the Provincial City who are already known, and none match the characteristics you provided."

After hanging up the phone, looking at the disappointed three women, Shen Qiang said, "Don't be discouraged, the demons of Heshenghe are just auxiliary, it's just a matter of luck. To really capture this killer, it seems we have to rely on our own thinking, after all, this guy can't possibly remain unchanged over so many years."

Glancing at the files, Shen Qiang said, "Furthermore, the psychological profile provided by the police clearly mentions that this person has a dual personality. So now what he appears to be may not necessarily be cold and unsociable, possibly even the opposite. Therefore, it's best we start the investigation from hospitals."

"Investigate in hospitals?" Ye Xiaolei looked surprised.

Shen Qiang nodded and said, "Fingerprint anomaly patients have another characteristic; they have no sweat glands, meaning they don't sweat, so their skin might be quite bad. If this guy cares about himself, he should have visited the hospital's dermatology department."

Upon hearing this, Qian Shanxue's eyes sparkled and said, "Great, let's go check that out now."

But just then, Ali couldn't help but pour cold water.

"My intuition tells me that searching this way won't find the person, because from the time he started committing crimes, he has been brazen and reckless. So can we understand it as him knowing that he's fingerprint anomaly and that the police can't easily track him?"

Ye Xiaolei immediately said, "Probably, otherwise he wouldn't have the guts to act so wantonly."

Qian Shanxue was stunned, "Does that mean he saw a doctor forty-three years ago? At that time, there were no computers, no internet, hundreds of hospitals' dermatology departments in the Provincial City, countless doctors. How do we check who saw him back then?"

Ali sighed and said, "Yes, if he visited doctors forty-three years ago, those doctors might not be around now. Plus, after so many years, who can remember those events?"

Hearing this, Shen Qiang frowned slightly and said, "Let's try starting with the most reputable provincial hospital of that time."
