In the evening.

Lin Feng rode the carriage and came to the famous West Market in Chang'an City.

Chang'an has one hundred and eight squares criss-crossed, with prosperous commerce, and is the most eastern and western cities in the world.

In the east and west cities, the east city is close to the imperial palaces such as Taiji Palace and Xingqing Palace, and the residences of officials and dignitaries are nearby, so the things sold are more advanced, which is commonly known as the place where luxury goods and high-end goods are monopolized.

Lin Feng lifted the curtain and looked out.

I saw people coming and going on the streets, street vendors shouting and shouting, juggling and painting circles, it was really lively, and it was even more lively than the so-called night market pedestrian street in later generations.

Lin Feng couldn't help but think of a few lines of Li Bai's poems.

"Wuling boy Jin Shidong, silver saddle white horse spring breeze."

"Falling flowers wander wherever they go, and laugh into the orchid restaurant."

The gold market refers to the West Market, and the Orchid Wine Store refers to the most distinctive restaurant in the West Market.

Datang accepts visitors from all over the world with an open mind that embraces all rivers and accepts all things, and it is not difficult for foreigners to live and do business in Datang, and because of its unique exotic characteristics, it is quite popular with ordinary people.

As a result, orchid liquor shops flourished in the western city of Chang'an, and too many literati lingered in it and were reluctant to leave.

Li Bai is one of the most representative figures.

After all, in his verses, Orchid has a high appearance rate.

In addition to the few lines of poetry just now, Lin Feng remembered a few more lines of poetry.

"Orchids look like flowers, and they should laugh in the spring breeze."

"Laughing in the spring breeze, dancing in Luoyi, you will return home if you are not drunk today."

When he saw these poems before, Lin Feng was thinking, how beautiful the orchids were, which could make Li Bai so worried, but he didn't expect to be able to meet those orchids in person today.

That's right, the place where Cheng Mumo feasted Lin Feng was an orchid restaurant, and it was also one of the three most famous orchid restaurants in the West City.

Just as he was thinking, the carriage stopped.

Zhao Fifteen's voice sounded: "Father-in-law, we have arrived." ”

Lin Feng nodded, Zhao Fifteen was originally a jailer in the Criminal Department, but now he has been transferred to Dali Temple, specifically responsible for protecting himself and waiting for his own dispatch.

And in addition to Zhao Fifteen, the guard on the surface, Lin Feng knew that there were at least a dozen guards who were secretly protecting themselves, and they were all specially applied by Xiao Yu to Li Shimin for themselves.

After all, the current self, to the Sixiang Organization and the former Dali Temple Cheng Lin Feng, is as dazzling as a lighthouse in the dark night, a thorn in their side, and the situation is still very dangerous.

After getting out of the carriage, I saw Cheng Chumo's figure.

"Hahaha, Lin Si Cheng...... No, you have to call Lin Sizheng! ”

Cheng Chumo's laughter was as hearty as his father Cheng Biting Jin.

Lin Feng smiled and arched his hand: "Tomorrow is the temple, and now it is still the temple, you can't talk nonsense, so as not to be heard by others, and it will not be good to spread it to other places." ”

Cheng Chu smiled silently: "It's okay, all the people who came tonight are my brothers, no one will chew the root of their tongue, but if Lin Sicheng thinks it's inappropriate, I will let them stop screaming." ”

Cheng Chumo is really hard to dislike...... Lin Feng nodded and said, "Thank you, Lieutenant General Cheng Lang." ”

Cheng Chumo welcomed Lin Feng into the wine shop, and said, "There are three people who celebrate for Lin Sicheng tonight, in addition to me. ”

Three?

Cheng Chumo's circle...... Is it also the son of other founding heroes?

Lin Feng was just about to ask, but Cheng Chumo had already led him to a table.

I saw three people sitting at the table.

The three are not very old, all of them are in their twenties, some are burly, some are handsome, and they have different temperaments.

Seeing Lin Feng coming, they all quickly got up and bowed their hands to Lin Feng.

Cheng Chumo smiled and introduced to the three of them: "This is the famous Detective Lin Sicheng. ”

Then he looked at Lin Feng again, introduced to Lin Feng the burly man beside him who was almost as burly as him, and said, "Lin Sicheng, this is Chi Baolin, the young secretary of the guard. ”

Yu Chi Baolin...... The son of the door god Chi Jingde?

"Lin Sicheng, long admiration!" Yu Chi Baolin had a very loud voice, and as soon as she opened her mouth, she attracted the attention of the drinkers at the other tables.

Lin Feng said with a smile: "I have heard that Wei Chi Shaoqing has excellent martial arts and extraordinary bearing, and when I saw it today, it really deserved its reputation." ”

Yu Chi Baolin is as straightforward as his father Yu Chi Jingde, and he is completely straightforward and honest with a martial artist, as soon as he heard Lin Feng's words, his eyes suddenly lit up, and he said with a smile: "Lin Sicheng really has good eyesight!" ”

Cheng Chumo's eyelids jumped, and it was just that Yu Chi Baolin, a fool, could take the scene seriously.

Lin Feng smiled sincerely: "Wei Chi Shaoqing's temperament is there, if Lin really can't see it, then it's strange." ”

Yu Chi Baolin was even happier.

Cheng Chu coughed silently, pointed to the man in the middle, who was dressed in a gorgeous costume, looked handsome, and had a tearful mole in the corner of his eye, and said, "Lai Guogong, Cizhou Thorn Shi Du Gou." ”

Lai Guogong!?

Lin Feng's eyes moved, those who can be called the Duke of the Kingdom are all people who made great contributions when Li Shimin made a fortune, such as the eldest grandson Wuji, Fang Xuanling and Cheng Biting Jin.

But the person in front of him is so young, not much older than Cheng Chumo, and he is the prince of the country at such a young age, which can only prove one point, he inherits the title of his father.

Plus his surname is Du...... Lin Feng had already guessed his identity.

The eldest son of the deceased Prime Minister Du Ruhui!

The famous fishing god in the fishing world! This is not a joke, Song Taizu personally ordered someone to build a temple for him, and the incense is continuous, and he is the real god of fishing.

Du Wei has a gentle temperament, but it implies a little majesty, the tears in the corners of his eyes make him very handsome, seeing Lin Feng looking at him, he chuckled lightly, his attitude was not close or alienated, giving people a very comfortable sense of socialization.

This unique temperament and the right sense of proportion in dealing with people and things are not found in Cheng Chumo and Wei Chi Baolin, it seems that Du Gou has taken on the responsibility of his father, and has grown a lot of money by going out to practice.

Lin Feng arched his hand and said: "The heroic deeds of suppressing bandits on the high seas of Laiguo, the lower officials have long been like thunder, as a literati, but he is not afraid of the ferocity of the bandits, and the art of war is thrown out casually, and the bandits will be easily exterminated, and then he thought of a unique method, using the strategy of fishing to strengthen the people and enrich the army, which is really the leader of the younger generation of my Tang Dynasty, and every time the lower officials think about it, they admire it in their hearts." ”

"I think if Du Sikong Quanxia knows about the achievements of Lai Guogong, he will be very pleased and proud."

When Du Wei heard Lin Feng's words, his warm eyes flashed slightly, he looked at Lin Feng, only to see that Lin Feng's eyes were clear and his smile was natural, he took a deep breath, solemnly returned the salute to Lin Feng, and said with a smile; "On the way back to Chang'an, I heard many times about Lin Sicheng's case-breaking deeds, and I was also very curious about Lin Sicheng.

Cheng Chumo glanced at Du Gou with some surprise, he knew Du Gou's temperament, Du Gou looked gentle, but in fact, he was very proud and cold in his bones, after all, when it came to status, among the younger generation, there was no one with a higher and more noble status than Du Gou.

And he didn't actually want to invite Du Wei tonight, although Du Wei was the same age as him, but after all, his status was completely different, but after hearing that he was going to have a banquet for Lin Feng, Du Wei took the initiative to ask to come along.

This made him not understand why Du Wei came now.

With his understanding of Du Gou, Du Gou's most polite and distant greetings were enough, but he didn't expect that he would say such beautiful words to Lin Feng.

Lin Feng's observation ability was extremely strong, and as soon as he saw Cheng Chumo's expression, he knew what he was thinking, Lin Feng smiled silently.

Du Wei inherited the title of Duke of Laiguo at a young age, and the pressure can be imagined, how many people are staring at him, how many people are waiting for his performance, and how many people are comparing him with Du Ruhui...... And as a literati, he personally fought against the bandits, just to show that he lived up to his grace and did not fall into the name of his father.

He praised Du Gou with reason and evidence, and said that Du Ruhui would be proud of his knowledge, which naturally meant that he was in Du Gou's heart.

Du Wei was happy, and as a return gift, he naturally had to praise himself, which was called a courtesy.

"This is the relict of the Ministry of Rites." Cheng Chumo introduced the last person to Lin Feng.

The ...... of the house is left behind Prime Minister Fang Xuanling's eldest son? The brother of the famous Fang bereavement?

Lin Feng looked at Fang Zhizhi, and saw that Fang Zhizhi was dressed in a Confucian robe, with an elegant temperament and a very bookish atmosphere, not like an official, but more like a scholar.

His eyes were clear, compared to Du Wei, who looked gentle and detached, there was more of a trace of bookish qi and righteousness, and in him, Lin Feng actually felt a trace of Wei Zheng's feelings.

He couldn't help but think of a sentence - a gentleman raises a heroic spirit.

Lin Feng said: "Before, the official didn't know what the specific performance of Haoran's qi was, but when I saw Fang Langzhong today, I understood what kind of bearing a real scholar should be. ”

Fang Yizhi heard Lin Feng's words, the whole person's expression was slightly startled, his eyes suddenly stared at Lin Feng, he was silent for a moment, and then said: "Lin Sicheng's eyesight is really extraordinary, he can see through what we think at a glance, it is rumored that Lin Sicheng is aware of everything, and he can always see the details. ”

Cheng Chumo was surprised again, how could he usually talk the least, just like Wei Zheng, who was not smiling, except for reading, Fang Zhizhi, who didn't want to talk nonsense, saw Lin Feng's first sentence, and actually said so many words?

He couldn't help but look at Lin Feng, his eyes were full of surprise, he knew that Lin Feng was very powerful, but now he felt that his understanding of Lin Feng was still too shallow.

Through the mutual praise with Lin Feng, Du Wei already had a certain understanding of Lin Feng's ability, and he was not too surprised.

Lin Feng chuckled and calmly greeted everyone's scrutiny.

"Sit sit, sit sit."

Cheng Chumo grinned and said, "Everyone is here, hurry up and drink." ”

A few people sat down, and the banquet opened.

With a good eye at first sight, the subsequent atmosphere is naturally very harmonious.

Cheng Chumo is very good at enlivening the atmosphere, Yu Chi Baolin drinks boldly, Du Gou knows the art of speaking very well after his experience outside, and the words make people feel like a spring breeze, and although Fang Yizhi does not talk much, he is very literate, quoting scriptures and classics, listening to Lin Feng's clouds and fog, and calling Niu Bi in his heart.

As for Lin Feng, not to mention, he is good at dancing with long sleeves, and his interpersonal communication level has reached the full level.

After a meal, Yu Chi Baolin pulled Lin Feng and wanted to bow down, Du Wei invited Lin Feng to go to Cizhou to meet in the future, Fang Yizhi even sent an invitation to Lin Feng to participate in the literati poetry meeting, Lin Feng hurriedly nodded politely: "Next time, I will definitely be." ”

Everyone was very satisfied with Lin Feng's "next time", and felt that Lin Feng was really a person worthy of friendship.

After drinking, everyone became more and more familiar, even Du Gou, who seemed to be gentle but alienated at the beginning, pushed the cup and exchanged glasses with Lin Feng, and when he was slightly drunk, Du Gou looked at Lin Feng and suddenly said: "Lin Sicheng, do you know that in fact, at the beginning, Lieutenant General Cheng Lang did not invite me?" ”

Hearing Du Wei's words, Lin Feng's eyebrows raised slightly, and Cheng Chumo's voice sounded: "Lai Guogong, you can be regarded as taking the initiative to mention this matter, if you don't say it, I have been itching in my heart......"

Lin Feng looked at Cheng Chumo, and Cheng Chumo said: "Lai Guogong is returning to Chang'an because of official business, and he will leave again after a short time, I am afraid of disturbing Lai Guogong's rest, so I don't want to invite him...... It was Lai Guogong who heard that I was going to celebrate Ling and took the initiative to come. ”

Lin Feng's eyes flashed slightly, he didn't think that the trivial matter of being promoted to a temple leader was worthy of the dignified Du Gou of Lai Guogong to come uninvited.

He pondered for a moment, and then said, "Lai Guogong, you should have come to me for something, right?" ”

Hearing Lin Feng's words, Cheng Chumo and the others immediately set their eyes on Du Wei.

Du Wei looked at Lin Feng apologetically and sighed: "Lin Sicheng, I'm sorry, I'm not just here to congratulate you...... To tell you the truth, I have a case and want to ask Lin Sicheng to help judge it. ”

"The case?"

Everyone was stunned, as soon as Lin Feng heard the case, he suddenly woke up, he was too sensitive to the case.

He sat up straight, looked at Du Gou, and said, "I don't know what the case is?" ”

Cheng Chumo and the others also looked at Du Wei curiously.

Du Wei said: "It was a homicide case that happened in Cizhou, and the case was not complicated, but because there was not enough evidence, the official could not determine who the murderer really was, and later returned to Chang'an on official business, and the case was shelved." ”

"On the way back, the official has been thinking about the case, but there is still no clear idea, I happened to hear about Lin Sicheng's case, and I learned that Lieutenant Cheng Lang was going to give Lin Sicheng a banquet tonight, so the official came with me, thinking that if it was Lin Sicheng, he might be able to help the official determine the real murderer."

Lin Feng understood what Du Wei meant, and he said in a deep voice: "I also ask Lai Guogong to inform the lower officials of the details of the case." ”

Seeing that Lin Feng didn't shirk at all, Du Wei's expression was even more gentle when he looked at Lin Feng, he didn't delay, and said directly: "This case happened a month ago. ”

"On that day, some people came to assassinate Shi Yamen to report the case, saying that they found that someone had been killed, and the official immediately took someone to investigate."

"As a result, the official found that the place of the crime was in a villager's house."

"In his compound, this villager was lying on the ground, he had suffered a severe blow to the back of his head, blood was pouring into a patch, the man was dead, and next to his body was a large blood-stained stone."

"According to the autopsy, there were no other wounds on the deceased's body, there were no traces of a fight before he died, the zombie was consistent with the time of death, and it was determined that the murder weapon was the stone, and the villager was smashed to the head with a stone behind him, and he was directly stoned to death."

Cheng Chumo and the others were seriously thinking about this case, and when they heard Lin Feng's voice, they suddenly remembered: "An acquaintance committed a crime? ”

Everyone was stunned and hurriedly looked at Lin Feng.

Du Wei's eyes lit up slightly, nodded directly, and said, "Lin Sicheng is really quick thinking...... Yes, according to the confessions of the neighbors and the results of the autopsy made by the deceased, the officer identified three suspects, and these three suspects were indeed acquaintances of the deceased. ”

Hearing Du Wei's words, Cheng Chumo and Yu Chi Baolin, the two martial artists, suddenly looked at Lin Feng with a shocked face, and almost called Lin Feng a cow pen.

And Fang Zhizhi, who was full of poetry and books, glanced at Lin Feng, although he was a little surprised, he was not as surprised as Cheng Chumo and them, it was obvious that he quickly deduced this.

Lin Feng saw Cheng Chumo and Yu Chi Baolin staring at him with beads in their eyes, and explained with a smile: "The place where the crime occurred is the courtyard of the deceased, which means that outsiders came to the deceased's house, and the murder weapon is a stone, which means that the perpetrator was not premeditated, but committed the crime with passion, and temporarily had the idea of killing, so he picked up a stone from the courtyard of the deceased and carried out the murder." ”

Cheng Chu was stunned for a moment, puzzled: "Why is the murder weapon a stone, so it is not a premeditated crime?" Why are you sure that the stone was picked up in the yard of the deceased? Not somewhere else? ”

Lin Feng explained: "It's very simple, Lieutenant General Cheng Lang, don't you take the place of that villager and think about it, someone is going to come to your house, call the door at the door, you go to open the door, if you see this person holding a big stone in his hand that is enough to kill you, will you let him enter your house?" ”

"Even if you can let him into your house, can you rest assured that you will give this man his back completely and let him follow you with a big rock that can kill you?"

"This ......" Cheng Chu pondered for a while, and then scratched his head: "It really won't." ”

Lin Feng said with a smile: "If it was a premeditated killing, wouldn't it be good to prepare a knife and dagger in advance?" It is easy to hide, and it will not be discovered and suspected by the deceased, and the success rate is higher, but with such a big stone, you can't hide it if you want to. ”

"Of course, if you have to be tough, say that he is premeditated, even if he is holding a big rock...... But the deceased is not stupid, when he sees someone coming to his house with such a stone, he will definitely be on guard, in this case, the murderer will definitely resist, so normally, in the case of the deceased being prepared and resisting, the murderer kills with a blunt object, and the hit should be in the forebrain, not the back of the head. ”

Cheng Chumo nodded suddenly: "I see." ”

But at this time, Fang Yizhi, who had not spoken, suddenly said: "Lin Sicheng, if the deceased is frightened by the murderer and runs in front, the murderer still has a chance to kill from behind, even if the deceased is on guard, it will still be the same result." ”

When Yu Chi Baolin heard this, she hurriedly said: "Yes, this is also possible. ”

The last thing Lin Feng was afraid of was that someone was more serious, he said, "But you ignored what you said. ”

"What?" Fang Zhizhi asked.

Lin Feng said: "If you say that the mortis of the deceased is the same as the time of death, it means that the mortis did not appear in advance, and the zombie did not appear in advance, which means that he did not exercise vigorously before he died...... If you are not a prisoner, you may not know that when a person exercises vigorously before death, it causes the protein in the body to coagulate at an accelerated rate...... Of course, you don't need to know what the protein is, you just need to know that the time of death of the deceased is exact, so that you can determine whether the deceased exercised vigorously before death according to the exact time of death, according to the deceased's mortis and physical changes. ”

"Therefore, if he did not exercise vigorously, it means that he did not flee for his life at all, and if he did not flee for his life, naturally there would not be a situation where he faced the back of his head with the murderer when he was fleeing for his life, and was stoned to death by the murderer."

Fang Yizhi's pupils dilated slightly, and after he was stunned for a moment, he looked at Lin Feng with a hint of admiration in his expression, and said, "It turns out that this is what the sentence was made, and the official really ignored it completely...... Lin Sicheng just listened to a few words from Lai Guogong, and he could think so thoughtfully, not bad at all, and he really deserved the name of a detective. ”

Yu Chi Baolin was also like a chicken pecking rice, and she agreed.

Lin Feng smiled and said, "There is a specialization in the art industry, this is my responsibility, naturally I have to think more than you think." ”

"According to what I just described, you should also know that the deceased not only let the murderer into the courtyard, but also gave his back to the murderer with great confidence, without any defense against the murderer, and did not think that the murderer would kill him at all, without any sense of crisis...... All these conditions can prove that the murderer must be someone he knows and knows. ”

Listening to Lin Feng's words, Rao likes to be more honest, and he can't help but nod in agreement.

And Du Wei, who had not spoken, also clapped his hands and praised: "After listening to Lin Sicheng's analysis without any mistakes, this official is more confident that Lin Sicheng can crack this case." ”

The reason why he didn't speak just now was because he wanted to see Lin Feng's ability with his own eyes, and Lin Feng's performance made him feel very amazing, although there were many people who could make these inferences, but like Lin Feng, there were very few people who could deduce all this perfectly after he had just introduced the case.

He said: "The murder weapon was indeed a stone in the courtyard of the deceased, which the murderer picked up casually. ”

Lin Feng nodded and said, "Who are the three suspects?" Why were they identified as suspects? ”

Du said: "When the deceased died, he let out a miserable scream, which alarmed the two neighbors next to him, and they hurriedly climbed over the wall to the deceased's house to check, and found that the deceased was dead. ”

"And when they reached the courtyard of the deceased, they saw a pedestrian passing by the door of the deceased on the road, and when they saw that the deceased was dead, they thought that the man was the murderer, and they quickly caught the man."

"After that, they went to the yamen to report the case."

"After the official arrived, he investigated the surrounding neighbors and villagers, and finally learned that at the time of the incident, it was when the heavy rain first stopped, many people were sheltering from the rain at home, no one went out, and there were witnesses who could prove that only the deceased and his neighbors lived alone, and it was impossible to prove whether they had left during the heavy rain."

"And the pedestrian happened to pass by the deceased's door at that time, and no one proved whether he had entered the deceased's house or not."

"So the three of them became suspects, and the murderer could only be one of the three of them."

Lin Feng nodded, and at the same time, the picture of the crime occurred in his mind.

The deceased was stoned to the head by the killer and let out a scream.

The screams alarmed the neighbors, and the two neighbors immediately climbed over the wall to check, found that the deceased was dead, and looked out of the door, just in time to see a figure, they thought it was the person who killed it, and controlled it.

Because the neighbor came over the wall, the speed was extremely fast, and there were pedestrians outside the door, if the other people were murderers, it was impossible to escape in such a short time without alarming the pedestrians outside the door.

So even if there is no testimony from other villagers, the murderer is definitely among the three of them.

Lin Feng pondered for a moment and continued to ask, "Is there anything missing from the deceased's house?" ”

Du Wei shook his head: "No." ”

Then it is impossible to determine the murderer based on what the deceased has lost.

He said, "Tell me about the three men and their confessions. ”

Du Wei did not delay, and immediately said: "The neighbor to the west of the deceased is called Li Feng, and he had a dispute with the deceased over land before. ”

"According to his testimony, he said that he was busy in the yard at the time of the crime, and it was raining heavily, and there was a lot of water in his yard, and he was using tools to direct the water out of the door to reduce the water in the yard."

"The official has gone to see it, and there is indeed a lot of water in his yard."

Lin Feng narrowed his eyes, his fingertips silently slammed on the table, and said, "What about the others?" ”

Du Wei glanced at Lin Feng and continued: "The neighbor to the west of the deceased is named Zhang Miao, he borrowed money from the deceased, but the deceased has not repaid the money, he has come to the door many times to ask for it, but the deceased has not paid it back, so he also had a conflict with the deceased. ”

"According to him, at the time of the crime, he was going to the toilet because of stomach discomfort, and at that time it was sunny after the rain, he raised his head and saw the sun that he had not seen for a long time, and he also saw a rainbow under the sun."

"The official went to his toilet to check ......"

Cheng Chumo's eyes widened directly: "You still went to see his deferential things?" ”

Du Gou's eyelids were fiercely raised, Rao is his self-cultivation, he almost didn't scold, he said: "This official is looking at the direction of his toilet, his toilet is facing southwest, and he can indeed see the sun when he raises his head." ”

Lin Feng nodded and said, "Lai Guogong is very serious and meticulous in investigating the case. ”

Du Wei said: "After all, this official can't determine the truth or falsity of their words, and he can only judge if he has seen them in person." ”

Lin Feng agreed, and he continued, "What about the pedestrian? ”

Du Wei said: "The pedestrian's name is Wang Wu, and he is also from the same village as the deceased, and the deceased and Wang Wu got together a few days ago because of some contradictions, and finally they were pulled apart. ”

"According to his confession, he happened to come down from the mountains to hunt at the time of the crime, but unfortunately, the road was slippery in the rain, the mountain road was difficult to walk, and the animals did not come out, so he didn't catch anything, so he had to leave empty."

"And at that time he happened to pass by the door of the deceased, and before he knew what was happening, he was held down by the deceased's neighbor."

Lin Feng thought for a moment and asked, "The way down the mountain is going to pass through the door of the deceased's house?" ”

Du Wei nodded: "That's right, there is only that way, so there is nothing wrong with his statement." ”

Lin Feng's eyes flashed slightly, and he fell into deep thought.

Seeing this, the others also frowned.

Cheng Chumo and Yu Chi Baolin stared wide-eyed, and their brains couldn't think of anything wrong with these three people.

In terms of motives, all three of them had conflicts with the deceased, and all of them had the possibility of killing.

But the confessions of the three sounded fine.

Moreover, the murder weapon was a stone in the deceased's house, and no clues could be found from the murder weapon.

It left the two of them with no idea at all.

Fang Yizhi also frowned, his dark eyes were full of thought, but he didn't gain anything for a long time.

Du Wei stared at Lin Feng with straight eyes, and he said: "The situation of the case is like this, the suspect can be determined, but the scope can no longer be further narrowed, there are no clues to prove the identity of the murderer at the scene of the crime, and the case is frozen." ”

"Rinji Cheng ......"

His eyes were full of expectation: "You solve the case like a god, can you find the murderer?" ”

Hearing Du Wei's words, the other three people also immediately looked at Lin Feng, except for Cheng Chumo, who had seen Lin Feng's case with his own eyes, the other few people had both expectation and doubt in their eyes.

At this time, they suddenly laughed when they saw Lin Feng.

Lin Feng's gaze swept over several people, and finally his gaze fell on Du Gou, and said, "Lai Guogong, I know who the murderer is. ”

Brush it up!

Hearing Lin Feng's words, everyone was stunned for a moment, and then their eyes suddenly widened.

Yu Chi Baolin was extremely shocked: "Lin Sicheng, you ...... Do you know who the killer is? ”

"You're going to solve the case!? Really? ”

Fang Yizhi also had a look of surprise in his eyes, but he was calm in his heart and did not show it like Yu Chi Baolin.

Du Gou leaned forward violently, his eyes were fixed on Lin Feng, and he couldn't help but speak directly: "Lin Sicheng, who is the murderer!?" ”

Looking at everyone's shocked and surprised expressions, Cheng Chumo hugged his arms, very indifferent, with a look of no surprise on his face.

After all, he had seen Lin Feng find out the murder of the envoy with his own eyes, what was this small case compared to the complicated murder of the envoy?

Even if he didn't have any ideas at all, it didn't hinder his confidence in Lin Feng.

Lin Feng said with a smile: "Do you know how the ghost was formed when the palace was haunted?" ”

Fang Yi's eyes flashed, and he said: "I heard my father say that that method is called small hole imaging by Lin Sicheng. ”

Lin Feng nodded: "The so-called small hole imaging, in fact, the principle is very simple, and it uses the characteristics of light. ”

"And this property is called direct light, which means that light travels in a straight line."

Fang Yi said straightly: "Later, I flipped through the classics, and found a record of small hole imaging in the "Book of Ink", although it is not called small hole imaging, but the principle is the same, it turns out that this is because of the straight line propagation of light. ”

Cheng Chumo and Wei Chi Baolin stared at each other again, didn't they solve the case and find the murderer? How did you start researching the light?

Yu Chi Baolin couldn't help but say, "Does this have anything to do with solving the case?" ”

Lin Feng smiled: "It has a relationship. ”

"In fact, the light we see everywhere has many properties."

"For example...... Reflection! ”

Lin Feng looked at everyone and said, "During the day, you pick up the smooth bronze mirror, face it at the sun, and then adjust the angle of the bronze mirror, what will happen?" ”

Yu Chi Baolin frowned and thought about it, not quite sure: "The sun's rays will be reflected in the mirror to other places?" ”

"That's right!"

Lin Feng nodded: "Because of the existence of mirrors, the sunlight is reflected by the mirror, which is called the reflection of light." ”

Fang Yizhi's eyes suddenly lit up, others didn't understand Lin Feng's words, but as a scholar and knowledgeable, he only felt that Lin Feng's words had a lot of truth.

He no longer pays attention to the case itself, but pays attention to the optical truth that Lin Feng told.

Lin Feng continued: "In addition to reflection, light also has an obvious property. ”

As he spoke, he picked up a chopstick, put it in the wine glass with wine, and said, "Let's take a look, what's wrong with the chopsticks?" ”

The crowd got up and craned their heads to look.

Yu Chi Baolin, who was rectum, immediately said: "It's bent!" Chopsticks are bent! ”

Lin Feng took out the chopsticks again: "What now?" ”

"Straight again!"

"Why?"

Yu Chi Baolin was stunned, how did he know why.

Fang Yizhi stared at Lin Feng closely, and heard Lin Feng say: "This is called the refraction of light, when light enters from one medium to another, the direction of propagation will change, so it will produce the strange scene we see. ”

Fang Yizhi's eyes became brighter and brighter, and he couldn't help nodding: "I see." ”

What a bachelor, he can keep up with my train of thought...... Lin Feng sighed in his heart, but except for Fang Zhizhi, even Du Wei had a blank expression on his face, knowing that popular science was here, and they would be completely stunned if they said more.

He looked at the crowd and said, "Light has many properties, and its properties will also create many things that we usually see, such as ...... Rainbow! ”

"Rainbow?"

Everyone was stunned.

Lin Feng said: "In fact, the formation of the rainbow depends on the reflection and refraction of the light I just mentioned, the light will continue to be reflected and refracted in the raindrops, thus forming a rainbow, and because of the characteristics of light, the appearance of the rainbow can never be in the same direction as it." ”

"That is to say......"

Lin Feng looked at Du Wei and the others, and said in a deep voice: "I don't know if you have noticed, the rainbow we often see after the rain, it ...... All appear in the opposite direction of the sun. ”

"If the sun is in the east, the rainbow will appear in your west."

"On the contrary...... If the sun is in the west, then the rainbow must be in the east! ”

"Therefore ......"

Lin Feng's voice paused, his gaze fell on Du Gou again, and said, "The second suspect, Zhang Miao, his confession said that he was in the toilet when the crime occurred, raised his head and saw the sun, and saw a rainbow under the sun...... It's absolutely impossible! ”

Du Gou's pupils shrank suddenly.

The whole person stood up suddenly.

The expression changed again and again.

Yu Chi Baolin looked dazed: "The rainbow and the sun really won't be in the same direction?" I never noticed. ”

Fang Yi frowned and pondered, the color of memory flashed in his eyes, and the next moment, his eyes widened, his eyes looked at Lin Feng tightly, his eyes were full of surprise at Lin Feng, and said, "Indeed, every rainbow I remember is indeed not in the same direction as the sun...... But it's so commonplace that I ignore it. ”

Lin Feng said with a smile: "I have never taken the initiative to observe purposefully, and even common things will be ignored." ”

Fang Yizhi couldn't help but say: "Lin Sicheng, how do you know all this knowledge?" Why have I read so many books and never seen them? ”

When Du Wei heard this, he couldn't help but look at Lin Feng curiously.

Lin Feng said: "I was persecuted by thieves when I was in prison, and I had problems with my memory, I don't remember many things, I remember this knowledge, but I don't remember where I saw it." ”

When Fang Yu heard this, he couldn't help but show regret and disappointment.

"But ......"

Lin Feng looked at Fang Yizhi, pointed to his brain, and said with a smile: "I still remember this knowledge, if Fang Langzhong wants to know something in the future, you can come to me, and we will discuss it together." ”

When Fang Yi heard this, he was not smiling and silent, and immediately said as quickly as possible: "Okay! In the future, the official will definitely bother! ”

Cheng Chu couldn't help but open his mouth wide, when did he see Fang Zhizhi so eager?

He couldn't help but look at Lin Feng deeply, Lin Feng really refreshed his perception of him again and again.

Even Du Wei's expression when he looked at Lin Feng changed again and again.

It was really Lin Feng who shocked Du Wei and the others too much tonight.

Terrifying reasoning ability, profound knowledge reserves, this is simply a god-man.

Lin Feng smiled, looked at Du Wei, and said, "Even if there is no rainbow principle that I just explained, just relying on experience, I can know that the rainbow will not be in the same direction as the sun, so ...... How could he possibly see a rainbow under the sun? It is clear that he is lying. ”

Du Wei took a deep breath, he bowed his hand to Lin Feng very seriously, and said, "Thank you Lin Sicheng!" If there is no Lin Temple to explain the problem of rainbows, unless the official happens to see the rainbow, the official will never think that the rainbow and the sun are always in the opposite direction! ”

"This time, Lin Sicheng helped the official find out the real culprit, and the official accepted Lin Sicheng's love, if Lin Sicheng has anything to do with the official, as long as the official can help, he will go all out."

Hearing this, Lin Feng let out a long breath.

Attract Fang Zhizhi with knowledge, gain Du Gou's favor with case judgment, and win the admiration and admiration of Yu Chi Baolin and Cheng Chumo with his ability.

Now, it's really time to start making friends with them.

I finally started to have my own circle.

Tonight, not in vain!
