Azan smiled bitterly, "Well, I shut up, the dragon can't beat the snake, I am in your hands now, and I have to bow my head."

He Chuyao smiled and said, "Just understand, you'd better obey our orders, otherwise just wait and suffer."

Luffy said, "By the way, He forensic doctor, didn't you say that you have toilet paper?"

"Yes, but I heard you arguing in the house. Forget it, I'll take it myself."

After He Chuyao finished speaking, he reached out and picked up a roll of toilet paper from the table, and waved to Luffy, "Let's go, I'll take you to verify that iron drill."

Gao Peng caught up, "I will go too."

He Chuyao shook his head, "Gao Peng, you have to stay and look at Azan, beware of him making tricks."

Gao Peng nodded helplessly.

Azan snorted coldly, "That is to say, people with IQ like you would think that if you lock me in a hospital bed, I can still play tricks."

He Chuyao said angrily, "Enough! You'd better be honest, otherwise I'll have to block your mouth." After that, he handed a towel to Gao Peng, "Hold the towel, if he makes noise again, you will use a towel to block it. Hold his mouth."

Gao Peng laughed and took the towel, "Don't worry, leave it to me."

Azan smiled bitterly, "Well, I shut up, I continue to sleep, you guys don't bother me anymore."

Luffy pushed He Chuyao out, "Go, let's continue to study that iron brace and ignore him."

He Chuyao laughed, and the two walked out one after another.

Azan said fiercely, "Neuropathy! Everything is abnormal."

Gao Peng raised the towel in his hand and coughed twice, "That Azan, shouldn't you be quieter? Otherwise, this towel is not acceptable?"

Azan said angrily, "Huh, your smile is so cheap."

Gao Peng sneered, "This is called a towel in hand, I have the final say."

Azan had to close his eyes angrily and continue to sleep.

Over there, Lu Fei and He Chuyao came to stand before the female corpse again. He Chuyao handed the phone to Lu Fei, "Come on, you help me light it up."

Luffy nodded and helped He Chuyao hold the phone.

He Chuyao took the toilet paper and wiped the blood on the iron braze, then unfolded the paper and observed carefully.

Luffy asked curiously, "What forensic doctor, what are you looking at?"

He Chuyao sighed, took out a clean toilet paper, and wiped the iron drill that had been wiped with blood. Then, he compared the blood-stained paper with the later paper. Lu Fei discovered that although there were no blood stains on the paper later, there were also a small amount of stains. It was precisely because of the presence of these stains that the paper became translucent.

He Chuyao asked Lu Fei holding two toilet papers, "Look at these two papers, is there any difference?"

Luffy frowned, "Well, the difference is, it seems that one is stained with blood and the other is not stained, but the one that is not stained with blood is also stained a little."

"Do you know what those stains are?"

Luffy shook his head, "I can't see it."

"Well, I know you can't see it. Let me tell you, these stains are oil."

"Oil? What oil?"

He Chuyao smiled, "What do you mean?"

Luffy smiled and said, "Oh, I'll guess if you are trying to test my posture. Since this iron drill passed through the female corpse's head, then these oil stains must be human oil, too. It's the oil on the female body."

He Chuyao laughed, "Don't be so terrible. Although this female corpse is fat and not a big fat pig, how can it be pierced with so much oil? Besides, iron pierced. The part of the body is still the head, not the thicker part of the body."

Luffy frowned, "What forensic doctor, you mean, these oils are not human oils?"

"Of course it's not human oil."

"If it's not human oil, then I can't think of what oil will be on this drill."

He Chuyao coughed and coughed, "Luffy, it seems that you have forgotten. I reminded you before. I said the purpose of this iron drill. Did you forget it so soon?"

Lu Fei smiled, "Naturally, I didn't forget. Didn't you just say that this iron drill looks like a lamb skewers?"

He Chuyao nodded, "Yes. So the oil on this paper, I think it should be sheep oil."

"Mutton? How could it be possible? Even if this drill is really a drill for wearing mutton skewers, it won't be mutton?"

"Of course, as for the brazier for wearing meat skewers, bamboo braziers are naturally disposable, while iron braziers are recycled. After customers eat the meat skewers, these iron braziers will not be discarded at will, but It was collected again by the restaurant owner, scrubbed, and kept for next use. In this case, it is not surprising that an iron drill has been reused many times, and there is mutton on the drill."

"Oh, if you explain it this way, I will understand."

"To verify my inference, you can smell the oil stains on this paper."

After He Chuyao finished speaking, he raised the piece of paper under Luffy's nose. Luffy frowned and sniffed it hard. Sure enough, he smelled a greasy mutton smell. After he was used to the smell of hospital disinfectant, he suddenly smelled it. The smell is so uncomfortable that I can't help but sneeze a few times.

He Chuyao smiled and said, "How is it? My inference is correct, right?"

Luffy frowned, "Well, I did smell a nasty smell. It seems that those oils are indeed mutton oil. He forensic doctor, your reasoning is absolutely correct. This iron drill was used to wear skewers in the past life. The drill, later, the murderer turned it into a murder weapon."

He Chuyao suddenly stopped smiling and frowned, "But now, the question is coming again, how can an iron brazier pierced with mutton skewers become a murder weapon and inserted into the dead woman's head? What kind of murderer would do How about using iron drills as a weapon to kill people?"

Luffy thought for a while, and smiled, "I understand, the murderer was the uncle who sold skewers. It must be the deceased woman who went to the uncle’s stall to cook the skewers. After eating, he didn’t pay for the skewers. According to her theory, the deceased woman had a hot temper. Not only did she not give money, she fought hard with her uncle. She was determined and wanted to eat the king's meal. The uncle was not a vegetarian, so he did. After the two played against each other, the uncle accounted for In order to gain the upper hand, he took advantage of the deceased woman’s attention, grabbed the iron drill and plunged it into the deceased’s eyes. Because the uncle was a cook, he used to cook vegetables all the year round, and his hands were very strong, so he immediately took the deceased’s head. It's pierced through. I think the truth is that. The murderer is the uncle who sells skewers. Legally speaking, the uncle's behavior should be a passionate murder. The uncle and the dead woman should have never met before. The only intersection between them is that the deceased woman went to his stall to eat skewers. He forensic doctor, my analysis is professional enough, praise me, and applaud."

After Luffy finished speaking, he laughed triumphantly.
