Duan Fei burped, and walked towards Zhennan with Shi Bin, Guo Wei and Yue Yuqi. Duan Fei did not dare to drink more, but he was still a little drunk. He walked ahead with his hands behind his back, feeling that he was quite majestic and upright.
Feeling proud, Yue Yuqi said: "Brother Fei, I drank too much. I need to find a place to relieve myself first."
Duan Fei grabbed Yue Yuqi's hand with his backhand and said with a drunken smile: "Yes, I'm a little anxious too, let's go together."
"Brother Fei, you're drunk..." Yue Yuqi frowned and said, deliberately pushing Duan Fei away, but held back.
"I'm not drunk, how can this little wine make me drunk? I think I was drunk back then, haha..." Duan Fei dragged the reluctant Yue Yuqi into a dark corner, shoulder to shoulder.
The two of them stood side by side and sprinkled a large amount of yellow water turned into yellow soup on the base of the wall. Duan Fei glanced at Yue Yuqi, and then laughed proudly. Yue Yuqi's face turned red with shame, but he was speechless.
The afternoon was not as busy as the morning. Duan Fei proudly took Yue Yuqi and Shi Bin for a walk along the street. A large amount of information continued to come to his hands. In one afternoon, they raided three other hiding places of the murderer and arrested him.
It's true that everyone's admiration for Duan Fei has reached a new high.
Seeing Duan Fei smiling mysteriously and playing with the porcelain doll in his hand, Yue Yuqi couldn't help but ask: "Brother Fei, do you like porcelain dolls very much? I took one at the scene and now I'm buying another one."
Duan Fei smiled and said: "No, these things I bought are all useful. These two porcelain dolls will tell me who the murderer is."
Yue Yuqi's eyelids twitched and he quickly asked: "Who is it?"
Duan Fei raised the porcelain doll in his hand and said: "As long as the murderer's hand touches it, the porcelain doll will tell me immediately!"
"So awesome?" All the detectives looked over one after another. Even Shi Bin, who knew Duan Fei's ability well, couldn't help but curiously wanted to reach out and touch it.
"You can't touch it casually, this is a treasure!" Duan Fei retracted his hand and hid the porcelain doll in his sleeve, determined not to let anyone touch it. He smiled mysteriously: "I want to take a bath and change clothes tonight, and put on incense.
Worship and ask for divine power so that we can catch the murderer early tomorrow morning!"
"Hey, you are pretending to be a ghost, I don't believe it!" Yue Yuqi shrugged his nose and said disdainfully: "I know this kind of deception. You just bought a candle because you wanted to burn some carbon black on it and then cover it up for people to touch.
If you dare not touch someone who has evil intentions in your heart, the secret will be revealed!"
Duan Fei's attention was guessed by Yue Yuqi, and he said angrily: "Don't believe it? If you don't believe it, just touch it and see!" Duan Fei held the porcelain doll in his sleeve and handed it to Yue Yuqi.
Yue Yuqi saw with his own eyes what Duan Fei bought at the street stall. How could he believe his lies? Under everyone's clamor, Yue Yuqi reached out and touched the porcelain doll unconvinced.
"No, it's not like this. You have to hold the porcelain doll with both hands like offering incense and worshiping Buddha..." Duan Fei demonstrated to Yue Yuqi, and Yue Yuqi had no choice but to follow it. Duan Fei's eyes flashed with joy, and he was nervous
He said quietly: "Let go, let go slowly..."
Yue Yuqi looked at his fingers suspiciously and said, "I can touch it now. Did the porcelain doll say anything to you?"
Duan Fei chuckled, used a piece of newly bought silk cloth to hide the porcelain doll in his arms, and said: "Now the power is not enough, it will not be able to speak to me until tomorrow morning."
Everyone booed, but Duan Fei smiled, clasped his fists and bowed in all directions, looking very proud of himself.
After wandering around for a while, Duan Fei returned to the government office. He first went to the mortuary to have a look. The widower, Old Yang, and his grandson Yang Sen had both woken up. Old Yang did not find any more clues. The body had been taken away by the Wang family.
After returning, it was said that he would be buried in two days.
Duan Fei took back the magnifying glass, returned to the bedroom arranged for him by Mr. Shi, closed the door, and stared at the two porcelain dolls on the table.
If there were modern investigative tools, he could now extract the murderer's fingerprints from the porcelain doll obtained from the crime scene and compare them with other people's fingerprints. However, he did not have fingerprint powder or transparent glue, so he could just use a magnifying glass.
The fingerprints were incomplete and blurry when he saw them, not to mention that in order to be used as evidence, he had to make the fingerprints visible so that others could see them at any time.
Duan Fei thought about it for a while and picked up the candle he bought in the afternoon. Yue Yuqi was right. When burning candles, fine carbon black will be produced. As far as Duan Fei knows, this should be the finest particle that humans can produce before the industrial age.
…
However, Duan Fei didn't plan to use the method Yue Yuqi said to solve the case. He hoped that the carbon black could reveal the fingerprints, and he would use white paper to copy the enlarged fingerprints. For the time being, he could only think of this method.
Duan Fei lit the candle wick. After the candle burned for a while, Duan Fei poured out the melted candle. The candle burned brightly and black charcoal smoke rose up. This was the result of the carbon polymer failing to undergo complete oxidation reaction. Duan Fei would
The porcelain doll I bought was placed on top of the candle and allowed to be roasted by the carbon smoke. After a while, the porcelain doll was covered with a layer of black soot.
Duan Fei used a magnifying glass to look at the porcelain doll carefully by the candlelight. After looking at it, he finally placed the porcelain doll heavily on the table with great disappointment, blew out the candle, and continued to lie down on the bed.
His attempt failed. Carbon black may not be suitable for use as fingerprint powder. It is too fine and has strong adhesion. The porcelain doll was so blackened that there were no traces of fingerprints at all. Duan Fei didn't know.
Because I chose the wrong materials or it was a problem with my own skills, using fingerprints to solve crimes is temporarily unavailable.
He hid in the room and did not come out until Shi Bin came to ask him to have dinner. Duan Fei appeared in front of everyone with a mysterious smile. A small setback could not stop him from moving forward. He carefully locked his room.
, announced to everyone: "I have already burned incense and worshiped the gods inside. A Bin and Guo Wei, you two take turns guarding the door tonight. No one is allowed to enter except me. Do you hear me?"
"Yes! Brother Fei, don't worry, we will never let anyone in!" Shi Bin and Guo Wei agreed loudly.
"Pretend to be a ghost..." Yue Yuqi curled his lips disdainfully. He really kept his promise and almost became Duan Fei's follower.
Duan Fei hugged him shoulder to shoulder and walked out, whispering: "What are you pretending to be? This is called science. Do you understand? Let me tell you, everyone has ten fingers, and each finger has
There is a unique fingerprint. Although there are countless people in the world, every fingerprint on our fingers is unique. I smoked the porcelain doll with a candle, and the fingerprints will slowly appear. Tomorrow morning, the fingerprints will be
It will appear, and when the time comes, a pair of fingerprints will be enough to capture it, right?"
Yue Yuqi seemed to understand. He suddenly shouted: "You tricked me into touching that thing. Do you still believe me? Do you want to use my fingerprints to compare it?"
Duan Fei patted him on the shoulder and said very affectionately: "How could it be? Now, except for a limited number of people, the one I trust the most is you. I borrowed your fingerprints just to do an experiment in advance. You know, I didn't have anything before."
We are sure, but we can’t just use the most important evidence for experiments? Wouldn’t it be bad if we messed up?”
Yue Yuqi said angrily: "Then you can't use your own fingerprints?"
Duan Fei laughed and said: "This is definitely the first fingerprint experiment in history. If your fingerprint is used, your name will be recorded in history! This is a supreme honor!"
"Glory, you big devil..." Yue Yuqi cursed bitterly: "You know how to quibble. Since you don't trust me so much, then I'll stay away from you."
Duan Fei held his hand tighter and said, "Don't be angry, I really trust you, so tonight I have a very secret operation. Only Mr. Shi and two other people know about it.
I didn't even tell my brother Shi Bin, are you interested in participating?"
Yue Yuqi doubted: "What are you trying to do again? Let me make it clear first. If you doubt me again or try to do any experiments on me, I will fall out!"
Duan Fei smiled and said: "No, no, don't worry, I promise not to make fun of you this time, but... I'm afraid you are not brave enough."
Yue Yuqi rolled his eyes at Duan Fei without saying a word, and bumped his armpit with his elbow. Duan Fei let go of his arm in pain, and shouted in pain: "Okay, I know you are brave, but I am not busy with this matter.
We can only do it in the middle of the night after everyone has gone to bed..."
