I'm not a genius detective

Chapter 168 It's impossible to possess such power.
After leaving the Municipal Bureau, Han Ling and Tong Feng drove to the gym, which was on the way, since the hospital was farther away than the gym.

"What are you talking about... sternal angle, does it require a lot of force?" Tong Feng, in the passenger seat, asked, having little concept of the rigidity of the human body.

Aside from specialized professions like forensic scientists and doctors, most people don't really have a concept of human anatomy; at most, they know about edible animals—because killing them isn't illegal.

Han Ling said, "Yes, we need to. Didn't you see that the murder weapon was bent and dented? That was a Western-style chef's knife. Although the blade was thin, it was still very hard."

Western-style chef's knives are designed to be relatively thin to achieve perfect cutting results, but the high-quality high-carbon steel and precise forging process still ensure the hardness of the blade, thus balancing sharpness and strength.

A Western chef's knife is not easy to bend, but how much force would it take to bend a murder weapon?

"Really?" Tong Feng recalled the knife in his house, still not quite understanding it. He didn't cook. "So you don't think he's the murderer? Or is there an accomplice? This feels like we're back to Hou Jiarou's case."

One person was missed in the Hou Jiarou case, and he personally experienced the process of conducting an investigation in another location while following Han Ling.

Han Ling: "I just wanted to confirm."

Tong Feng said "Oh": "How do you know that the sternal angle requires a lot of force to penetrate? I don't think we learned that in the police academy, right? The autopsy report didn't mention it either. Your knowledge is a bit scattered."

"Heh." Han Ling sneered, "Experience comes from practice."

"???" Tong Feng turned to look at Han Ling's profile. "Don't joke like that. By the way, can we pierce through it?"

Han Ling: "Yes, most normal adult men are fine, but patients with late-stage cancer will become very weak and experience a significant decrease in strength due to the combined effects of the disease and treatment."

Tong Feng nodded: "That's right. I know that chemotherapy and radiotherapy can kill cancer cells but also damage normal cells, causing side effects such as fatigue, nausea, and loss of appetite, which can further aggravate physical weakness."

"Huh? Now that you mention it, Zhang Zhenhua killed three people, all using violent methods. That's pretty impressive."

Han Ling: "Just ask and you'll find out."

The two arrived at the gym.

It was very late, the gym was closed, but the lights were still on inside, and the doors were locked from the inside.

Han Ling called out twice, which brought the boss out.

The owner is very young, looking to be under thirty. To be able to open a gym in Qingchang, he must either be a second-generation rich kid or have made his first fortune in his early years.

"Brother, what time is it?" The boss mistook the two for customers.

Han Ling took out his ID and explained with a smile. When he learned that the other party was a policeman, the young boss's attitude softened, and he opened the door to invite the two of them in.

After inquiring, we learned that the owner lives in the gym and has rooms on the second floor.

"Zhang Zhenhua, huh? We're familiar with him. He's been coming here often these past two years. Didn't he just call? Was it the Municipal Bureau?" The shopkeeper poured water for the two of them.

Han Ling nodded: "Yes, we want to know the results of Zhang Zhenhua's training, mainly in the last three months."

Boss: "The results?"

Han Ling added, "The effect on strength."

The boss then understood: "He's sick, so he's not very strong. He can only lift two or three kilograms of dumbbells, less than ten kilograms of bench press, three or four kilograms of overhead press, and two kilograms of bicep curl."

Han Ling: "They're all very light, how come you remember them so clearly?"

The owner laughed and said, "It's not easy to see a regular customer. In places like gyms, everyone only goes for a short time. They might come here on a whim to work up a sweat today, but we might not see them for the next two months."

People as self-disciplined as Zhang Zhenhua are quite rare, so he left a deep impression on me. I often gave him free pointers on his movements.

Han Ling nodded and asked, "I think his muscles are pretty good, is that reasonable? How did he do that?"

Cancer patients have difficulty building muscle because cancer cells prioritize consuming nutrients.

Boss: "He controls his diet and supplements his protein intake. His diet is very standardized, even more so than mine and the gym trainers. I have to admire him."

Han Ling: "So he just looks muscular, but he's not actually very strong."

Boss: "You could say that."

"Thank you."

"You're welcome."

The two left the gym, and the owner closed the door completely this time.

Han Ling stood there, took out a cigarette and lit it. Tong Feng, who was standing next to him, said, "Can you prove that Zhang Zhenhua didn't have the means to commit the crime just by looking at his fitness scores? When people are angry and under high stimulation, they can unleash power beyond their own capabilities. I think there's nothing wrong with this case."

"Let's go to the hospital and get checked out. We can ask the doctor about the medical records," Han Ling said.

Zhang Zhenhua is receiving treatment at Qingchang People's Hospital, the same hospital where Xu Qinghe works.

Han Ling hadn't seen her for a while.

Upon entering the hospital, Tong Feng headed straight for the emergency room.

"Where are you going?" Han Ling called out to him.

Tong Feng turned around and said as he walked, "Go find your girlfriend. Why don't we both go through all this trouble when we know someone there?"

"Huh?" Han Ling didn't know what to say at this moment. The emergency room was very close to the gate, and Tong Feng had already found Xu Qinghe's location while they were delayed.

Xu Qinghe is at work tonight.

"Hello!" Tong Feng greeted Xu Qinghe, who was seeing patients, since there were no patients at the moment.

Xu Qinghe looked up and saw Tong Feng. Her eyes brightened slightly. Tong Feng's arrival meant that Han Ling was likely here as well. It was so late; Tong Feng couldn't possibly be loitering around the hospital, and he didn't seem to be sick.

Sure enough, Han Ling soon appeared behind him.

The room not only had Xu Qinghe, a doctor, but Han Ling's appearance also attracted their attention. He was Xu Qinghe's boyfriend, so they had to take a good look at him.

It's no exaggeration to say that among all the female doctors in Qingchang, there's probably none more beautiful than Xu Qinghe. The single male doctors in the hospital have long since mentally torn Han Ling to pieces.

"Aren't you busy?"

Han Ling walked in and greeted Xu Qinghe.

He finds the current relationship between the two parties very comfortable.

If this woman had a sense of boundaries and was mentally sound, she would be much more pleasing to the eye.

"I'm not busy, why did you come over?" Xu Qinghe stood up, stepped forward and gave Han Ling a light hug, whispering in his ear, "Just to help me out, some colleagues don't believe I have a boyfriend."

Han Ling understood, smelling the girl's unique fragrance, and gently stroked her hair.

The sweet scene made the other colleagues sigh, wondering how this young policeman managed to win over Dr. Xu.

"Can you stop provoking me?" Tong Feng complained.

The two separated, and Han Ling took Xu Qinghe's hand and walked out, saying, "I need your help with something."

In the corridor, Han Ling explained the situation to Xu Qinghe.

This visit to the hospital was a routine police investigation, and the hospital had a responsibility to cooperate. However, Tong Feng was right; having an acquaintance could indeed save a lot of trouble, at least time.

"Huh?" Xu Qinghe was puzzled after hearing Han Ling's words. "Excessive protein intake by cancer patients will increase the burden on their liver and kidneys. Late-stage cancer patients have very weak liver and kidney function. What is he trying to do?"

Han Ling said directly, "I want to kill someone."

The word "murder" made Xu Qinghe's gaze sharpen. After a moment of silence, she said, "Come on, I'll take you to Director Li. He's an authority in this field. The person you're talking about should be seen by Director Li."

The two followed Xu Qinghe upstairs to the ward area, where Director Li was on duty that night.

It's clear that Xu Qinghe is a celebrity at the hospital; everyone on the street greets her warmly, though it's unclear whether it's because of her good looks or her high level of skill.

Xu Qinghe pushed open the door to the director's office without even knocking.

Having witnessed Xu Qinghe's status in the hospital, Tong Feng thought to himself that he had to cultivate a good relationship with her. Who could guarantee that they wouldn't get sick in their lifetime? Hmm... First, he would build a good relationship with Han Ling and give her a computer next year.

In the future, there will be no need to register for medical treatment, and even the scarce hospital beds may be reserved.

"Xiao Xu? What brings you here?"

"Is this your boyfriend? First time meeting him, hello, hello."

Director Li was a middle-aged man. He wasn't wearing a white coat; he was wearing a t-shirt, casual pants, and sneakers, and looked very energetic.

Upon learning Han Ling's identity and purpose, Director Li was very helpful and immediately retrieved Zhang Zhenhua's medical records.

“I have a deep impression of him.” Director Li showed Han Ling the medical records. “Statistically speaking, he wouldn’t live that long, but miracles can happen with any disease. Treatment is only an auxiliary means; how well he recovers depends on the patient himself.”

Maintaining a good mindset is more important than anything else. When you have a good mindset, your brain secretes a variety of neurotransmitters, which can directly or indirectly activate immune cells and improve the efficiency of engulfing pathogens.

Conversely, if a patient is negative, the hormones they secrete can suppress the activity and number of lymphocytes. Therefore, mindset is extremely important, and for seriously ill patients, it directly affects lifespan.

Tong Feng listened attentively, preparing to tell his parents the exact words when he got home.

Han Ling quickly browsed through Zhang Zhenhua's medical record. The record was very detailed, including family history, past medical history, current medical history, and comprehensive physical examination records, covering all aspects without any blind spots.

Suddenly, his gaze froze as the words "hypokalemia" came into view.

"Hypokalemia..." Han Ling read it aloud.

Upon hearing this, Director Li explained, "Oh, that's alright. Compared to cancer, Zhang Zhenhua's hypokalemia is not serious. At most, the clinical manifestation is muscle weakness, and its progression is faster than cancer..."

"Myasthenia gravis?" Han Ling interrupted, turning to look at Director Li. "Zhang Zhenhua has myasthenia gravis?"

Director Li: "Yes, muscle weakness is the most typical clinical manifestation of hypokalemia. It starts from the lower limbs, making it difficult to climb stairs, and gradually spreads to the upper limbs."

Hearing this, Tong Feng was stunned for a moment, feeling that Han Ling was really weird and a bit too weird.

Why does every case end with a big surprise?
"Director Li!" Tong Feng couldn't help but ask urgently, "Is it possible that Zhang Zhenhua used a knife to pierce the angle of the sternum?"

Director Li looked at Tong Feng: "Sternal angle? It's very hard. A normal man can do that."

Zhang Zhenhua was already in the late stages of cancer, his body was weak and his strength was declining. In addition, he had hypokalemia, so it was impossible for him to have this kind of strength.

What happened? He stabbed someone with a knife?

Tong Feng: "..."

It's over, it's ruined.

I made a mistake again.

Zhang Zhenhua was not the one who killed Li Dechang.

Even the person who killed Xiong Chuan and Wu Cuicui might not necessarily be him.
