He Chuyao smiled and said, "Then you mean that at that time, the strong man was peeing before he fell into the water?"

Luffy nodded, "Yes, I just said that if a man as fierce as a strong man, if not because he was peeing at the time, would he be pushed into the river so easily by the uncle?"

He Chuyao smiled and said, "Then now, the problem is coming again. You just said that the uncle killed the mother and the son, and then ran to the river to find the uncle. This process takes ten minutes to get together. Isn't this wrong?"

Luffy nodded, "Yes."

He Chuyao smiled and said, "Luffy, according to your reasoning, the strong man was always peeing when the uncle killed someone."

"Yes. Is there any problem with this?"

Lu Fei looked at He Chuyao with confusion in his eyes. Obviously, he didn't think there was any problem with his reasoning.

He Chuyao smiled and said, "The problem is big. You just said that after the uncle killed someone, he ran to the river. This process takes ten minutes. During the whole process, the strong man has been peeing. In other words, the strong man peeed for ten minutes. Minutes, and, you just said that when the uncle found the strong man, he was still peeing. In other words, the strong man spent ten minutes in this peeing, but he hadn't finished it?"

"This--"

Lu Fei was startled, completely speechless.

"Luffy, have you noticed your reasoning problem now? No one can do it. You have to pee for ten minutes without finishing it."

Lu Fei coughed and said awkwardly, "Maybe this brawny man, who doesn't know how to cleanse himself and loves himself, has a venereal disease, so he will always pull scum and urinary when he urinates."

"It's impossible to urinate for ten minutes. Even if you have some ulterior venereal disease, you can urinate in ten minutes, but according to your settings, you can't urinate in ten minutes."

"This--"

Luffy was speechless again.

"Luffy, so your reasoning is very problematic."

Lu Fei was denied again, obviously very depressed, but he was still not convinced.

"He forensic doctor, we shouldn't count all ten minutes as the time for the strong man to pee. In these ten minutes, the strong man might wander by the river for a while."

He Chuyao smiled and said, "Wandering? This word is very interesting. A guy who almost diaperses his crotch, does he still have time to wander?"

"Oh, even if you are peeing by the river, you have to choose a good place? So, I said he wandered for a while, that's right."

"Well, you're right. Wander first, then you continue."

"So, these ten minutes are actually the time the strong man wandered by the river, plus the time to pee. Of course, the wandering accounted for a large proportion. For example, the strong man wandered for seven minutes and used it to pee. three minutes."

He Chuyao coughed twice, "Luffy, let me ask you again, do you know how long it takes for the human body to urinate?"

Luffy frowned, "About three minutes."

He Chuyao smiled, "Three minutes? For such a long time, it seems that you should go to see a doctor."

Luffy smirked, "Hey, I didn't actually pay attention. I just estimated it casually."

He Chuyao said, "Let me tell you. Normal urination time ranges from ten seconds to dozens of seconds, and it will never exceed one minute."

Luffy was so startled that he couldn't close his mouth. "Huh? Such a short time? I thought it would take two or three minutes."

"Yes, so the three minutes you said is impossible at all. If a person insists on urinating for more than three minutes, it can only be hematuria. Because normal people do not store so much urine in the bladder."

Luffy coughed and scratched his scalp, looking embarrassed. He Chuyao laughed so hard that he couldn't straighten his waist.

He Chuyao smiled and said, "Luffy, do you still insist on the speculation that the strong man ran to the river first and then peeed?"

Luffy nodded, "Yes, the strong man wandered by the river for nearly ten minutes before he found a suitable place to pee."

He Chuyao smiled, "Well, Lu Fei is a very serious and good classmate, and immediately extended the wandering time to ten minutes. Now, the problem reappears. The uncle is killing people at the meat skewers stall. Since it is a murderer, the person killed. There will be screams, the uncle killed the mother and the son one after another, and the strong man wandering by the river has not heard any sound? You know, the kebab stall is next to the river, and there is no wall in between. And the time of the attack at that time, according to your guess, was in the middle of the night, you should know that the night is very quiet, as long as there is a little noise, you can penetrate a long distance, let alone the harsh screams. "

Lu Fei sighed, "Well, it's quiet in the middle of the night. The brawny man should be able to hear the shouts."

He Chuyao smiled and said, "That's even more ridiculous. Hearing the screams of his wife and children, this strong man still continues to wander by the river?"

At this time, Luffy was completely choked, so he said in embarrassment, "He forensic doctor, don't worry, let me think about it again."

He Chuyao smiled, "Student Lu Fei, your reasoning is getting more and more untenable. No man hears the screams of his wife and children, and can continue to wander around calmly instead of saving others. According to you The strong man clearly heard the screams of his wife and children, but he was still hovering by the river for ten minutes. After that, he unzipped and peeed calmly. This kind of reasoning is too funny. Right?"

Luffy hissed, "He forensic doctor, don't get excited. With your excitement, my thoughts are disrupted by you again."

"Okay, I won't speak anymore, you think slowly."

This time, Luffy thought for a long time before speaking again.

"He forensic, I understand."

"Well, what do you understand?"

"I understand that the fundamental reason why the strong man wandered by the river for ten minutes before urinating calmly was because the strong man did not hear the screams of his wife and children."

"Ah? How is it possible? The meat skewers stand is next to the river. How can a strong man wandering by the river not hear the screams of his wife and children?"

Lu Fei smiled, "According to common sense, the strong man should be able to hear the scream, but now the strong man does not hear the scream. What is the reason?"

He Chuyao sneered, "Luffy, are you planning to sell it to me again?"

Lu Fei smiled, "Okay, I won't sell it, I'll tell you directly. The reason the strong man didn't hear is because this strong man is deaf."

"Huh? Deaf?"

Lu Fei smiled, "In other words, he has a severe hearing impairment. Therefore, he did not hear the screams of his wife and children while wandering by the river. Moreover, when the uncle walked behind him and attacked, he had hearing problems. , Also failed to find out in time, so he was pushed into the river by the uncle."

"Deaf? Is it really deaf?"

He Chuyao walked to the corpse again, stood on tiptoe, and looked at the corpse's ears thoughtfully.
