Lu Fei suddenly realized, "Oh? So you did this experiment to verify what kind of mark will be left on the chest of the stall owner after the deceased's brain and blood drip?"

He Chuyao nodded, "Yes." Then he raised the toilet paper to Luffy again, "I believe you have seen it clearly. In fact, this paper shows exactly what happened after the deceased's brain dripped down. The imprint of presentation."

Luffy was taken aback, "Huh? No? At present, we just assume that the paper ball, chopsticks and toilet paper are the deceased’s head, iron drill, and the stall owner’s chest. In fact, when the drill penetrates the deceased’s head, blood And the brain plasma falls at the same time, not just the brain plasma."

He Chuyao smiled and said, "Of course I understand this truth. Now let's ignore the dripping blood and just count the brains."

Luffy frowned, "That's it. Forensic doctor, your setting is too weird."

He Chuyao smiled, "After ignoring the dripping blood, we only consider the dripping brains. As we have seen so far, when the chopsticks penetrated the entire paper ball, the paper ball broke, and at the same time, the water in the paper ball started. Drip down along the chopsticks, drop by drop on the toilet paper on the table."

Luffy nodded, "Well, I agree with this."

He Chuyao smiled and said, "Okay, I will continue to analyze. The reason why the water droplets fall from the chopsticks is entirely due to gravity. Because at this time, the paper ball, chopsticks and toilet paper are on the same vertical line."

Luffy nodded, "Well, I agree with that."

He Chuyao smiled and said, "Then the water droplets fall from a vertical height and drip onto the toilet paper. They will never form splashes. They will only gather in the center of the toilet paper to form a small round piece. I just said, this The three things replaced the deceased’s head, the drill and the stall owner’s chest. Therefore, if the deceased’s head, the drill and the stall owner’s chest slide down along the same vertical line, they will never fall There are splattered white spots on the stall owner’s chest, and there may be small white spots, but the number should be very small, and there is no large round white mark on the stall owner’s chest. This shows that, The white dots on the stall owner’s chest are not formed because the three are on the same vertical line."

Lu Fei immediately exclaimed, "Ah? What? He forensic doctor, I was really confused by you."

The old man smiled and said, "Little classmate, what are you confused about? What forensic doctors can analyze clearly. What forensic doctors mean is that when the deceased’s head, drill and the stall owner’s chest are on the same vertical line, It will only leave a round white mark on the stall owner's chest, just like the toilet paper he is holding, with a round mark in the middle."

Luffy said in surprise, "I understand. But at the moment, the brains on the stall owner's chest are splashes of white dots, not a large round piece. What's going on?"

He Chuyao smiled and said, "According to my analysis, this kind of splash-like dots should be formed by the deceased's head, drill and the stall owner's chest at the same level."

"Same level? But what forensic medicine, why is it the same level?"

The old man and Luffy opened their mouths in surprise.

He Chuyao nodded, "Yes, the three must be on the same horizontal plane to leave this small white spot on the stall owner’s chest. If they are on the same vertical line, the one left on the stall owner’s chest will be a large circle. I think this toilet paper soaked in water has shown us clearly."

After He Chuyao finished speaking, he raised the toilet paper again.

The three of them stared at the toilet paper that was soaked in water, and they all fell into silence. All three of them were thinking hard about what was going on at the time.

For a long time, Lu Fei coughed and coughed, "He Forensic Doctor, according to your analysis just now, the white spots on the stall owner’s chest were formed when the deceased’s head, drill and stall owner’s chest were on the same level, then Now, let’s redesign the situation at that time. At that time, the serial killer-oh, heh, here is the reasoning of the old man, and the serial killer is temporarily set as the murderer. At that time, the serial killer pierced the female with an iron drill. The head of the deceased, the female deceased did not die immediately, she immediately screamed, and rushed towards the stall selling skewers standing in front of her, shouting, save me! Please help me! The stall owner I have never seen such a horrible scene. I was so scared that he backed away. Seeing that his mother was injured, the son of the deceased woman wanted to rush to fight the murderer desperately—"

He Chuyao smiled, "Luffy, let me interrupt here. The murderer pierced her head with an iron drill. She didn't die immediately. Then, at that time, shouldn't her son protect her first? The injured mother ignored it and went to fight the murderer instead?"

Luffy groaned slightly and said with a smile, "This I think, first of all, because the son is worried that if the murderer is not stopped, the murderer will harm his mother again, so he chose to attack the murderer rather than help his mother."

He Chuyao nodded, "Well, I reluctantly accept this reason."

Luffy smiled, "Okay, I'll go on. The murderer saw his son rushing over, and immediately picked up a stone and killed him. However, at this time, the deceased woman was a little bit pierced with iron on her head. She became unconscious, so she chased the stall owner, seeing the stall owner as the murderer for a while, and then the stall owner as the savior, calling the stall owner to save her. The stall owner knew that she was crazy, plus her current situation. Looks like, oh, with an iron brace on his head, looks terrible, scared the stall owner straight back, but back, the stall owner felt his back hit a hard object, The impact caused pain in the back and the leaves fell. The stall owner turned his face and saw that he had hit the old locust tree by the river. As he was about to dodge to escape, the dead woman had already rushed over again. And this time, the stall owner did not move away. The deceased woman's pounce happened to hit the stall owner’s chest. At this time, it happened that the dead woman’s head, drill and the stall owner’s chest were on the same level. , The stall owner saw the crippled face of the deceased woman up close and exclaimed and died of heart spasm. The deceased woman was also paralyzed under the tree due to lack of physical strength. At this time, the stall owner had died and the dead woman was still on the ground. Struggling, the murderer came over, stretched out his hand to try the stall owner's snort, smiled triumphantly, and hung up another one."

After Luffy finished speaking, he laughed triumphantly, "What forensic doctor, how about it? This time the reasoning should be fine, right?"

He Chuyao didn't say a word, and the old man just looked at him directly, making Luffy very embarrassed.

"Hey, you two are talking, I've been talking for a long time, why should you give me some applause?"

He Chuyao smiled and said, "Applause should naturally be reserved for people who can fully explain the truth."
