Duan Fei hiccuped, and Shi Bin, Guo Wei and Yue Yuqi walked to the south of the town, Duan Fei didn't dare to drink more, but he was also a little drunk, he took the lead with his hands behind his back, feeling quite a bit majestic, and was proud, only to hear Yue Yuqi say: "Brother Fei, I drank too much, I have to find a place to solve it first." ”

Duan Fei grabbed Yue Yuqi's hand with his backhand, and said with a drunken smile: "Yes, I'm also a little anxious, let's go together." ”

"Brother Fei, are you ...... drunk" Yue Yuqi said with a frown, having the intention to push Duan Fei away, but he held back.

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

The two of them sprinkled a large amount of yellow water turned into yellow soup on the root of the wall side by side, Duan Fei's eyes glanced at Yue Yuqi, and then laughed proudly, Yue Yuqi was only blushing, but he couldn't make a sound.

The afternoon was not as busy as the morning, Duan Fei triumphantly took Yue Yuqi and Shi Bin to walk along the street, and a large amount of information continued to be collected into his hands, and in one afternoon, they copied the murderer's other three hiding places, and one by one, everyone's worship of Duan Fei reached a new high.

Yue Yuqi saw Duan Fei smiling mysteriously and kept playing with the porcelain doll in his hand, and couldn't help but ask, "Brother Fei, do you like porcelain dolls very much?" Took one on the spot and now buy another. ”

Duan Fei smiled: "No, I buy these things are all useful, these two porcelain dolls will tell me who the murderer is." ”

Yue Yuqi's eyelids jumped, and he hurriedly 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 godly?" The crowd quickly looked over, and even Shi Bin, who knew Duan Fei's ability, couldn't help but reach out and touch it curiously.

"You can't touch it casually, it's a baby!" Duan Fei shrank his hand and hid the porcelain doll in his sleeve, resolutely not letting everyone touch it, he smiled mysteriously: "Tonight I want to bathe and change clothes, put on incense and worship, please bring divine power to catch the murderer early tomorrow morning!" ”

"Snort, pretending to be a ghost, I don't believe it!" Yue Yuqi shrugged his nose and said disdainfully: "I will also do this kind of trick, you just bought a candle, you want to burn some charcoal black on it, and then cover it for people to touch, people with ghosts in their hearts will not dare to touch it, and they will be exposed!" ”

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! Duan Fei held the porcelain doll in his sleeve in his palm and handed it to Yue Yuqi.

Yue Yuqi saw with his own eyes the things that Duan Fei bought at the stall, how could he believe his nonsense, under the clamor of everyone, Yue Yuqi was unconvinced and reached out and touched the porcelain doll.

"No, it's not like this, you have to hold the porcelain doll with two hands like worshipping the Buddha like incense......" Duan Fei demonstrated to Yue Yuqi, Yue Yuqi had no choice but to do it, Duan Fei's eyes flashed with a hint of joy, and he said nervously: "Let go, let go slowly......"

Yue Yuqi looked at his fingers suspiciously, and said, "Now that I have touched it, did the porcelain doll tell you?" ”

Duan Fei smiled, used a newly bought silk cloth to hide the porcelain doll in his arms, and said, "Now the divine power is insufficient, and it must speak to me tomorrow morning." ”

Everyone booed together, but Duan Fei smiled and clenched his fists in all directions, looking complacent.

After a short walk, Duan Fei returned to the government office, he first went to the mortuary to take a look, Lao Yang and his grandson Yang Sen had woken up, Lao Yang did not find more clues, the body has been taken back by the Wang family, it is said that it will be buried in two days.

Duan Fei took back the magnifying glass, returned to the bedroom arranged for him by Shi Zongyu, closed the door, and began to be in a daze at the two porcelain dolls on the table.

If there were modern investigative tools, he would have been able to extract the murderer's fingerprints from the porcelain doll obtained from the crime scene, and then compare them with other people's fingerprints, but he has no fingerprint powder, no transparent glue, even if he sees the fingerprints with a magnifying glass, they are mutilated and blurred, not to mention that to be used as evidence, he has to make the fingerprints appear so that others can see them at any time.

Duan Fei thought about it for a while, picked up the candle he bought in the afternoon, Yue Yuqi was right, when burning the candle, it would produce a fine carbon black, as far as Duan Fei knew, this should be the finest particle that humans could make before the industrial age......

However, Duan Fei didn't plan to use the method that Yue Yuqi said to solve the case, he hoped that the carbon black could show the fingerprints, and he would use a blank paper to copy an enlarged fingerprint, and he could only think of this method for the time being.

Duan Fei lit the wick of the candle, after the candle burned for a while, Duan Fei poured out the melted candle, the candle flame was in full bloom, and the black charcoal smoke rose, which was the result of the failure of the carbon polymer to completely oxidize the reaction, Duan Fei put the porcelain doll he bought on top of the candle, and let the carbon smoke roast, and the porcelain doll was covered with a layer of black soot after a while.

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

His attempt failed, carbon black may not be suitable for use as fingerprint powder, it is too subtle, the adhesion is strong, the porcelain doll is blackened, and there are no traces of fingerprints at all, Duan Fei doesn't know if it is because he chose the wrong material, or because of his own technical problems, in short, the road of using fingerprints to solve the case is temporarily impossible.

He hid in the room and didn't come out until Shi Bin came to call him for dinner, Duan Fei appeared in front of everyone with a mysterious smile, a small setback could not stop him from moving forward, he cautiously locked his room and announced to everyone: "I have already put incense in it and worshiped God, Ah Bin, Guo Wei, you two take turns guarding the door tonight, no one is allowed to enter except me, do you hear!" ”

"Yes! Don't worry, Phineas, we'll never let anyone in! Shi Bin and Guo Wei agreed loudly.

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

Duan Fei walked out with his arms around his shoulder, and said in a low voice: "What are you pretending to be a ghost, do you understand this called science, let me tell you, everyone has ten fingers, and each finger has a unique fingerprint, although there are countless people in the world, but every fingerprint on our fingers is unique, I smoke it with a candle on the porcelain doll, and the fingerprints will slowly appear, and the fingerprints will appear tomorrow morning, and when the time comes, a pair of fingerprints, isn't it accurate to catch one?" ”

Yue Yuqi didn't seem to understand when he heard it, and he suddenly shouted: "You tricked me into touching that thing, don't you still believe me, do you want to use my fingerprints to compare?" ”

Duan Fei patted him on the shoulder and said very affectionately, "How could it be? Now, except for a limited number of people, I trust you the most, I borrowed your fingerprints just to do an experiment in advance, you must know that I was not sure before, I can't just take the most important evidence to experiment, right? Wouldn't it be bad if it messed up? ”

Yue Yuqi said angrily: "Then you won't use your own fingerprints?" ”

Duan Fei laughed and said: "This is definitely the first fingerprint experiment in history, with your fingerprints, your name will go down in history in the future!" What a great honor! ”

"Glory to you big devil...... Yue Yuqi scolded hatefully: "I will quibble, since you don't trust me so much, then I will stay away from you." ”

Duan Fei hugged his hands tightly, and said: "Don't be angry, I really, really trust you, so let's do it, I have a very secret operation tonight, only Mr. Shi and the other two people know about it, and even my brother Shi Bin I didn't tell him, are you interested in participating?" ”

Yue Yuqi was suspicious: "What the hell do you want to do?" I'll make it clear first, if you doubt me or try to do anything with me, I'm going to turn around! ”

Duan Fei smiled and said, "No, no, don't worry, I promise not to joke with you this time, but ...... I'm afraid you're not bold enough. ”

Yue Yuqi rolled his eyes at Duan Fei without saying a word, and hit his armpit with an elbow, Duan Fei let go of his hand in pain, and exclaimed bitterly: "Okay, I know you are bold, but this matter is not busy, you have to wait until everyone sleeps in the middle of the night to do it......"
