Chapter 91: Key Clue, 0.618 Golden Ratio! ,Su Ming’s Speculation

This left Xu Changsheng and Lin Tian somewhat puzzled, with an indescribable sense of astonishment.

Because they had no idea what exactly led Su Ming to deduce that the murderer of the dismemberment case at Magic City University was more likely to use a hammer grip, which is more convenient for exerting force?

He also ruled out the two common grip methods for doctors, the bow grip and pen grip, used for holding knives.

Of course, the most important thing was…The hammer grip is typically used for striking and chopping, tasks that involve broad, sweeping motions rather than fine, detailed ones.

But now.

Based on the video records they had seen.

The murderer in this dismemberment case appeared to be extremely meticulous, with outstanding knife skills.

Otherwise.

How could the size and shape of the dismembered body parts be so consistent?

Yet the hammer grip is typically not used to train knife skills.

After all.

Who has ever seen someone use the rough hand gesture of holding a hammer to practice precise knife skills?

……

It seemed that Su Ming noticed the confusion on Lin Tian and Xu Changsheng’s faces.

Without hesitation, he picked up the remote control on the table and chose to replay the video of the murderer dismembering the body.

The eerie images of bloodied hands reappeared. When the murderer exposed their palm covered in blood and prepared to display the victim’s head from various angles, Su Ming immediately pressed the pause button and zoomed in on the bloodstains on the murderer’s palm.

Then Su Ming walked swiftly to the screen, pointed to the uneven blood stains at the top of the murderer’s left palm, squinted his eyes, and made his deduction aloud.

“Director Lin, Brother Sheng.”

“First, from the analysis of the victim’s body parts and the position of the head’s fracture, we can confirm that the murderer is a left-handed person.”

“So, when handling heavy objects or swinging tools, the murderer would certainly habitually use their left hand.”

“Additionally.”

“From the murderer’s prominent finger joints and numerous healing and recent cutting injuries on the side, it’s clear that their work or training experience is not short.”

“Now carefully observe the blood stains at the top of the murderer’s left palm. Do you see the subtle variations in the depth of the bloodstains?”

“This is clearly different from the uniform blood stains at the center.”

Upon hearing this, Xu Changsheng furrowed his brow and, after a few seconds of careful thought, shook his head and said with some confusion.

“Xiao Ming, what could these uneven blood stains possibly indicate?”

“From any angle, this seems very coincidental, and it doesn’t seem to serve as a viable clue or evidence.”

“It’s like the murderer’s hand pressing in blood of varying depths, causing the bloodstains on the palm to be inconsistent…”

Before Xu Changsheng could finish speaking.

Lin Tian interrupted by tapping the table, slightly unsure, and explained.

“No, Ah Sheng.”

“Look at the uniform blood stains in the murderer’s palm, this indicates that their entire hand must have pressed into the blood.”

“But the varying depth of blood stains on the palm is curious, and coupled with Xiao Ming’s earlier point about the hammer grip that facilitates force.”

“Think about it.”

“Doesn’t the hammer grip require the entire palm to press tightly against the tool’s handle, especially the top of the palm, to secure it and prevent it from slipping?”

“Because of this.”

“During intense training and tool handling, the top of the palm would repeatedly rub against the handle, causing abrasions that eventually form thick calluses.”

“And jobs like those of doctors or forensic experts don’t require using a hammer grip, let alone developing calluses on the palm.”

“However.”

“From the meticulous way the murderer cut the body and the skilled technique displayed.”

“This murderer might…Use a hammer grip to exert force in daily work or training, but also requires fine, precise cutting and dissection.”

“To meet both of these criteria, the profession I can think of is…Butcher, chef, duck butcher, tuna fish cutter, etc., but that’s still not quite right.”

At this point, Lin Tian suddenly discarded his previous theory, furrowed his brows and lightly sniffed his index finger for tobacco smell, speaking slowly.

“Based on the posts from the dark web.”

“The details we inferred yesterday suggest that the murderer should have a relatively high social status, along with significant fame and wealth.”

“Also, judging by the state of the murderer’s hands in the video, it’s clear they’ve undergone specific hand care, but occupations like chefs and butchers don’t have a need for such hand care.”

“The most crucial point is…These professions don’t have a clear status gap with university students, so it’s hard to link them to this case as the post described.”

At the same time, Xu Changsheng also came to understand the significance of the varying blood stains on the murderer’s palm. He then followed up with Lin Tian’s thoughts.

“Master, it’s not just that.”

“If it were an ordinary profession like a chef or butcher, there would be no need to hide the left-handedness.”

“After all.”

“There are plenty of people working in these fields, and being left-handed alone wouldn’t be a distinguishing feature, so there would be no need to go to such lengths to conceal it.”

“Moreover, I remember a line in that post.”

“To avoid suspicion as much as possible, the best approach is to let the prey come to you and cover up all traces of your actions.”

“I think it’s unlikely that a profession like a butcher would have any appeal to a university student, let alone have them cover up their movements.”

“So the murderer’s occupation must be very unique, one that would have a certain appeal to university students.”

At this moment.

The entire meeting room fell silent.

Su Ming and the other two began to seriously consider what kind of profession could meet all these requirements.

A profession where the person works with their hands.

Where the fingers frequently sustain cuts.

Where tools need to be gripped tightly for long periods, involving heavy striking or cutting motions, leading to calluses on the palm.

A profession that is also adept at fine cutting work, capable of making body parts consistent in size and shape.

A profession with fewer people, better economic conditions, and one that holds a certain attraction or value for university students.

A profession with a significant social status gap compared to university students, making it difficult to connect it to the case.

From the way the victim’s body was dismembered, the murderer should also be familiar with human joints and tissues.

……

The three of them kept pondering.

The video continued to play in the background. Su Ming leaned comfortably in his chair, tapping his right index finger against his left hand’s back, squinting as he cleared his mind.

In his mind, he continued to filter through professions that could match so many criteria.

Just then.

The only words the murderer spoke in the dismemberment video slowly entered Su Ming’s relaxed mind.

“It’s even more urgent and captivating than the 0.618 golden ratio.”

“This is truly a perfect… truly perfect work!”
