Everyone didn't speak, they were all looking at Jiang He. Jiang He walked forward silently, leaving everyone behind. No one knew what Jiang He was doing or what he was thinking, but everyone pinned their hopes on Jiang He. They believed that, just like every time before, Jiang He could always find more subtle clues from the smallest details.

A brand new one hundred yuan, with a very strong ink smell. But if it is a RMB that has been in circulation for more than a few years, the smell of ink will gradually disappear, and it will be replaced by the taste of countless lives. No one would deliberately smell the renminbi, and at this time, Jiang He was doing it.

Pictures emerged in Jiang He's mind:

It was a noisy Sichuan restaurant, the restaurant was small, but there were many patrons. This one-hundred-yuan note was handed over from the diners to the boss. That's right, the money has a taste of Sichuan restaurant.

It was a worker who had access to the sewer. He got up from the damp and cold sewer, took the one-hundred-yuan bill handed over by the customer, and stuffed it into his pocket at will. A rotting, cold sewer smell.

It was a scavenger who picked up garbage. He filled a tricycle with the bottles and cans he picked up, and then took it to the junk station to sell it. He took the hundred-yuan bill with his dirty hands. It smelled like a junkyard.

It was a criminal consultant dressed in black. He used trinitrotoluene to make TNT explosives in a dark abandoned chemical factory. After that, he gave the hundred yuan to the kid near Jiang He's house.

And now, this note fell into Jiang He's hands.

So how did the criminal advisor get the bill? One hundred yuan is the banknote with the largest face value. It cannot be recovered from shopping. It can only be paid by someone else, or stolen, or simply bought. I don't know how many hands this banknote has passed through, but only these kinds of flavors can be smelled by Jiang He.

Explain that this is a recent smell.

Sewers, Sichuan restaurants, garbage dumps, TNT, no, there is a smell of rain.

"Xu Yiman!" Jiang He suddenly opened his eyes and said to Xu Yiman, "The composition of rain in the chemical industry area is different from that in the non-chemical area, right?"

"Yes." Xu Yiman nodded: "There is a lot of different dust in the rain. If the environment of the two places where the rainfall is different, then the composition of the rain is naturally different."

Jiang He put the 100 yuan back into the evidence bag and said to Xu Yiman, "Check the chemical substances on this 100 yuan piece, maybe we can narrow it down a bit."

Elder Shao came over and asked Jiang He, "Do you have any clues?"

Jiang He nodded and said to Mr. Shao, "The smell of explosives, the smell of strong peppers, the smell of sewers, the smell of garbage, and the smell of rainwater. If this is the clue that Wei Demian left us, then as long as It's good to know if there is an element in the money that is not found elsewhere."

Elder Shao patted Jiang He's shoulder and said, "Very good, it's autumn rain now, and it has been raining for a long time in many places in Longcheng. And because of the rain, the sewers in some places are indeed blocked. If We found a Sichuan restaurant that once had a clogged sewer and needed someone to clean it up, and the scope was basically determined."

Jiang He said, "But I'm not more than 50% sure, I can't determine the order of money circulation, so it may be a hundred and eight thousand miles away. The chance is very small, so small that I don't want to believe it myself. "

Shao Lao looked into Jiang He's eyes, he pointed at Jiang He's chest, and said, "When you got this coin, did this idea suddenly pop into your mind?"

Jiang He looked down at his chest and said, "Yes."

Elder Shao grabbed Jiang He's hand and placed it on Jiang He's chest, and said, "If it's a thought that pops up in an instant, it's called intuition. This kind of thought appeared in his mind for no reason, but after thinking about it, There is also a certain truth. What is needed to solve a case is evidence, reasoning, and logic.”

"But sometimes, solving a case also requires intuition." Shao Lao looked at Captain Liu who was fighting the fire in the distance, and then looked at Jiang He and said, "Logical ability and reasoning ability can be practiced, but intuition alone cannot be practiced. It came out. That's why others call this kind of thing talent, superstitiously, it was taught to you by God's blessing."

"Look." Shao Lao said: "This time, abandon your probability theory and gamble with your own intuition."

After speaking, Shao Lao said to Yuan Jun: "Yuan Jun, arrange it immediately, all the people will find a restaurant, this restaurant can't be in the city center, it is better to be near the old industrial area, the sewers of this restaurant have been blocked, So I hired a sewer master to clean it up."

"It's still the restaurant owner who is looking for this sewer." Yuan Jun asked, scratching his head.

"Look for everything." Shao Lao said.

"What about the southern suburbs?" Yuan Jun asked.

"Leave him alone." Shao Lao said firmly.

Several people understood now that Elder Shao had put all his hopes on Jiang He this time. If Jiang He's guess is correct, then he is likely to find Wang Chao within twelve hours. If Jiang He's guess is wrong, a lot of police force will be wasted and everyone's hard work will be in vain.

It's just that Jiang He's reasoning is too bizarre, too avant-garde.

But several people did not have any doubts, because earlier, Shao Lao told them one word - trust.

Xu Yiman said: "We must go back to the city bureau immediately. If we want to test this hundred yuan, we can't do it in a few hours."

Shao Lao nodded and said, "As soon as possible."

Yuan Jun drove the crowd back to the Public Security Bureau, but no one in the car spoke.

Wang Chao had been missing for three months, and they didn't even know about it. When Wang Chao recovered and was discharged from the hospital, several people were busy investigating the case, and they never congratulated Wang Chao. But time has passed, and in an instant, things have changed. Wang Chao has become a wanted prisoner in the city, and they are on their way to arrest Wang Chao.

Twelve hours may seem like a long time, but everyone understands that every minute and every second that passes now is the passing of life.

When Xu Yiman took the one-hundred-yuan bill to test, there were still ten hours left.

Jiang He stood motionless in the courtyard, waiting for Xu Yiman's result. At this moment they have no clue, all they can do is wait.

Pieces of leaves fell from the front of Jiang He, fluttering in the wind, lying on the ground. Autumn told everyone in this straightforward way that she was here.

Jiang He watched the leaves fall one by one, and after a while, there was a small pile of fallen leaves beside him. Looking at the fallen leaves on the ground, Jiang He suddenly stood up. A thought flashed in his mind for a moment, the fallen leaves, which he had seen in one place.

It is different from the fallen leaves here. Although the fallen leaves here fall randomly, they do not cover the entire yard. Most of these leaves are concentrated in one area. Although there are fallen leaves in other places, they are very few. The fallen leaves in the yard are dense and scattered, some areas are more, some areas are less.

Jiang He understood that this was the meaning of randomness. Random does not mean that the fallen leaves will randomly cover the entire yard, but that the probability of falling here is high, and the probability of falling elsewhere is small.

"Old Shao!" Jiang He shouted as he pushed open the door of the conference room.

Elder Shao was holding his tea jar and thinking with his eyes closed. Hearing Jiang He's words, he stood up abruptly and said, "Are there any results from Xu Yiman?"

Jiang He shook his head and said, "No, I have a clue about Lu Zhengye."

"What?" Shao Lao asked.

Jiang He motioned for Mr. Shao to come out with him, and said, "Elder Shao, when we were at Wei Lingyong's house, we saw fallen leaves in the yard. He said that he had never cleaned them, and those leaves were from the big tree outside. The fallen leaves from the tree, right?"

"What's the problem?" Shao Lao asked.

Jiang He pointed to the ground and said, "But the leaves here haven't been cleaned either. In a yard that hasn't been cleaned, there should be more fallen leaves in a certain area and less leaves in a certain area. Either because of the location of the tree, or because of the wind blowing. But, the fallen leaves of Wei Lingyong's house are covering almost every corner of his yard."

"This shows that he didn't clean it, but after careful care, he evenly spread the leaves all over the yard."

Jiang He looked at Mr. Shao and analyzed, "Before Wei Lingyong persuaded Wei Linghui to leave Lu Zhengye, but after Lu Zhengye was released from prison, Wei Lingyong did not persuade his sister again. This is not logical."

Shao Laoyi clapped his hands and said, "Yes, if it wasn't for Wei Lingyong who felt that he couldn't separate the two and chose to give up. Then Wei Lingyong knew that Lu Zhengye would no longer be able to pester his sister, that is to say …”

Jiang He and Shao Lao said together, "Wei Lingyong killed him!"

Shao Lao said: "That's right. No wonder when the police went to his house and asked him some basic questions, he would drink so many glasses of water nervously. I thought he was feeling guilty for his daughter at the time. , but now it seems that he is afraid that we will see that he killed Lu Zhengye."

"If Lu Zhengye was killed by him, then Lu Zhengye has been dead for at least 88 days." Shao Lao said, "Where do you think he hid the body?"

Jiang He said decisively: "The latrine. I noticed that he looked at the latrine in the courtyard several times. He drank so much water, but he had no intention of going to the toilet. If he threw Lu Zhengye's body into the cesspool , then everything can be explained.”

"Call the rest." Shao Lao said: "We will set off immediately and leave the detection of the hundred-yuan bills to the others. If Lu Zhengye is found, then this clue is more important than the hundred-yuan bills."
