Touring the Ming Dynasty

Duan Fei hiccupped, and walked towards Zhennan with Shi Bin, Guo Wei, and Yue Yuqi. Duan Fei didn't dare to drink too much, but he was also a little drunk. Complacent, he only heard Yue Yuqi say: "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 also in a hurry, let's go together."

"Brother Fei, you're drunk..." Yue Yuqi frowned, intending to push Duan Fei away, but held back.

"I'm not drunk, how can I get drunk with this little wine? I think I was a huge amount back then, haha..." Duan Fei dragged the reluctant Yue Yuqi into a dark corner with his arms around his shoulders.

The two 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 triumphantly. Yue Yuqi blushed with shame, but kept silent.

In the afternoon, he was not as busy as in the morning. Duan Fei complacently took Yue Yuqi and Shi Bin for a walk along the street, and a large amount of information continued to be collected in his hands. In one afternoon, they copied the other three hiding places of the murderer. To be sure, everyone's admiration for Duan Fei has reached a new high point.

Seeing Duan Fei smiling mysteriously and constantly playing with the porcelain doll in his hand, Yue Yuqi couldn't help asking: "Brother Fei, do you like porcelain dolls very much? You took one at the scene, and now you're buying another one."

Duan Fei smiled and said, "No, I bought these things for use. These two porcelain dolls will tell me who the murderer is."

Yue Yuqi's eyelids twitched, and he hurriedly asked, "Who is it?"

Duan Fei raised the porcelain doll in his hand and said, "As soon as the murderer's hand touches it, the porcelain doll will tell me immediately!"

"So amazing?" All the arresters looked over one after another, and even Shi Bin, who knew Duan Fei's abilities well, couldn't help but want to reach out and touch Duan Fei curiously.

"You can't touch it casually, it's a treasure!" Duan Fei hid the porcelain doll in his sleeve, resolutely not letting anyone touch it, and he said with a mysterious smile: "Tonight I'm going to take a bath and change clothes, and burn incense. Worship, please use divine power so that we can catch the murderer tomorrow morning!"

"Hey, pretending to be a ghost, I don't believe it!" Yue Yuqi shrugged his nose and said disdainfully: "I can also do this kind of blindfolding. You bought a candle just now to burn some charcoal black on it, and then cover it for people to touch. People with ghosts in their hearts will reveal their secrets if they dare not touch them!"

Duan Fei's attention was guessed by Yue Yuqi, and he said angrily: "Don't believe me? If you don't believe me, just touch it!" 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 nonsense, under the clamor of everyone, Yue Yuqi stretched out his hand to touch the porcelain doll dissatisfied.

"No, it's not like this, you need 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 suit. Duan Fei's eyes flashed with joy, he was nervous Xi said: "Let go, let go slowly..."

Yue Yuqi looked at his fingers suspiciously, and said, "Now I feel it too, did the porcelain doll tell you anything?"

Duan Fei chuckled, and used a piece of newly bought silk cloth to hide the porcelain doll in his bosom, and said: "Now the power is insufficient, it must be able to talk to me tomorrow morning."

Everyone booed at the same time, but Duan Fei smiled and clasped his fists and bowed to all sides, looking very satisfied.

After a short walk, Duan Fei returned to the Yamen Office. He went to the mortuary first to have a look. Both Lao Yang and his grandson Yang Sen had already woken up, and Lao Yang did not find any more clues. I went back, and it is said that I will be buried in two days.

Duan Fei took back the magnifying glass, went back to the bedroom that Mr. Shi arranged for him, closed the door, and stared blankly at the two porcelain dolls on the table.

If there were modern investigative tools, he could already extract the murderer's fingerprints from the porcelain doll obtained from the crime scene, and compare them with other fingerprints. Even when he saw the fingerprints, they were incomplete and fuzzy, not to mention that to be used as evidence, he had to make the fingerprints appear so that others could see them at any time.

Duan Fei thought about it for a while, and picked up the candle that he bought in the afternoon. Yue Yuqi was right. When burning a candle, there will be fine carbon black. As far as Duan Fei knows, this should be the smallest particle that humans can produce before the industrial age. ...

But Duan Fei didn't intend to use the method Yue Yuqi said to solve the case. He hoped that the carbon black could show the fingerprints, and then 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, and after the candle burned for a while, Duan Fei poured out the melted candle, and the candle was full of flames, and black charcoal smoke rose up, which was the result of the incomplete oxidation reaction of the carbon polymer. The porcelain doll I bought was placed on top of the candle, and the charcoal was allowed to smoke. After a while, the porcelain doll was covered with a layer of black soot.

Duan Fei looked carefully at the porcelain doll with a magnifying glass by the candlelight, looked at it, and finally put the porcelain doll heavily on the table in disappointment, blew out the candle, and continued to lie on the bed.

His attempt failed. Carbon black may not be suitable for use as a fingerprint powder. It is too fine and has strong adhesive force. The porcelain doll was so blackened that no trace of fingerprints could be seen at all. Duan Fei didn't know what it was Because I chose the wrong material, or because of my own technical problems, in short, using fingerprints to solve the case is temporarily impossible.

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 locked his room carefully. , and announced to everyone: "I have already burnt incense and worshiped gods inside, Abin and Guo Wei, you two will take turns guarding the door tonight, and 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.

"Pretending to be a ghost..." Yue Yuqi curled his lips in disdain, he really kept his promise, and he was about to become Duan Fei's follower.

Duan Fei walked out with his arms around his shoulders, and said in a low voice: "What is pretending to be a ghost? This is called science, do you understand? Let me tell you, everyone has ten fingers, and each finger has ten fingers. There is a unique fingerprint. Although there are countless people in the world, each fingerprint on our fingers is unique. I use a candle to smoke on the porcelain doll, and the fingerprints will slowly appear. In the morning, the fingerprints will disappear It will appear, when a pair of fingerprints, isn't one accurate?"

Yue Yuqi half-understood, he suddenly shouted: "You lied to me to touch that thing, don't tell me you still trust me, do you want to use my fingerprints for comparison?"

Duan Fei patted him on the shoulder and said affectionately: "How could it be? Except for a few people, you are the one I trust the most. I borrowed your fingerprints just to do an experiment beforehand. If you are sure, you can't just use the most important evidence to experiment? Wouldn't it be bad if you screwed up?"

Yue Yuqi said angrily: "Then you don't know how to use your own fingerprints?"

Duan Fei laughed and said: "This is definitely the first fingerprint experiment in history. With your fingerprints, your name will be recorded in the history books in the future! This is a supreme honor!"

"Glory, you big bastard..." Yue Yuqi cursed bitterly: "You can argue, since you don't trust me so much, then I'd better stay away from you."

Duan Fei hugged his hands a little tighter, and said: "Don't be angry, I really really trust you, so I have a very secret operation tonight, and 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 the hell are you trying to do? Let me make it clear first. If you doubt me or want to use me for experiments again, I will turn my face!"

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 elbow on his armpit. Duan Fei let go of his hand in pain, and cried out in pain: "Okay, I know you are bold, but this matter is not busy, we have to We can only do it in the middle of the night when everyone is asleep..."
