Street Day. Guangong Town rushes to the streets on the third and eighth days of the lunar calendar every month.

At four o'clock in the morning, the eaters had already gotten up, started a fire, soaked flour, stuffed with stuffing, put on the steamer, and sold rice noodles and all kinds of pasta were already busy. There are constantly sellers in the vegetable market who put all kinds of dishes such as chili, eggplant, loofah, water spinach, cauliflower, tofu, chicken, duck and fish on the stalls that have been picked up in the afternoon before. The blacksmith has already burned the furnace, and the sound of sorting coarse materials and finished products can be heard in the shop, where the farmers' kitchen knives, hoes, and plows are all purchased.

From five o'clock to six o'clock, the villagers of each village poured into the town in groups of three or five. The endless vegetables grown by the family, the endless cubs raised by dogs and cats, the squeezed rapeseed oil, tea seed oil, bamboo and firewood on the mountain, are all picked up or carried to the market in the town, sold for change, and bought new clothes, children's snacks, pesticides and fertilizers. On this day, the young people who stay at home to work as farmers will put on the most fashionable and good-looking clothes that they are usually reluctant to wear, wipe their shoes, put nylon socks on their feet, and walk around the street for hours in high spirits.

Today is a Saturday, there are no classes at school, and Xu You plans to go for a walk on the street.

During this time, everyone was unhappy, and Wu Ping took turns summoning people he thought were suspicious. The place where classes and accommodation were held was also turned upside down by the police investigating the case.

The autopsy results have come out, Zhou Guoqiang died of a throat injury on the day of the school anniversary, and the murder weapon was an iron disc, and the murderer did not know. Wu Changan died of a heart attack and respiratory failure caused by chronic poisoning, and the murderer is unknown. There has been no progress in the two murder cases so far, and the county public security bureau has held a special meeting to study and make arrangements for the investigation work.

Shortly after coming out of Wu Chang'an's house that day and talking to Wei Chili, Xu You found the doorman Li Chuang, under the pretext of drinking. Drinking is Li Chuang's hobby.

Xu You asked a lot about the school, and Li Chuang seemed to be deliberately avoiding important topics, picking out anecdotes about Zhou Guoqiang's death and the unusual situation at the school before he was killed, Li Chuang either kept silent or shook his head to say he didn't know. In Li Chuang, Xu You didn't get anything.

Wu Ping was also clueless, he sat on a stool in the conference room and smoked wildly.

Wu Ping focused his main energy on searching for the source of the murder weapon, and if he found the source of the murder weapon, it would not be difficult to find the person who bought the murder weapon or bought parts to make the murder weapon, and this person was either a murderer or an accomplice. "Keep looking. Department stores, hardware stores, blacksmith shops, carefully investigate one by one. "He gave instructions to the criminal police who handled the case." It is a controlled chemical, and it is difficult to buy it in the market, so ask for underground buyers through other means. ”

"Martial arts team, I have a classmate who is engaged in chemistry, I asked him, *** can refine and make it yourself." Criminal policeman Liu Debao took Wu Ping's words. He is tall, sturdy, clever and diligent, and is Wu Ping's apprentice, and he is very liked by Wu Ping.

"You ask about the raw materials for making ***, make a list, and let the brothers take a look. On the one hand, we investigate the finished product, and on the other hand, we investigate the raw materials, and we do it at the same time. ”

Wu Ping continued, "There is one more thing that needs to be done immediately. On the day of the incident, Wu Changan's wife, Li Xuelan, told me that he had made a trip back to his hometown of Pingyang shortly before the accident. Wu Changan died of chronic poisoning, and the intake was very small, so the people he had been in contact with in the period from half a month to a month before his death had to be investigated. He glanced around and arranged, "Bao, you take a few brothers and go to Pingyang." ”

Xu You had already taken a turn on the street.

He didn't plan to go back to the school cafeteria for lunch, so he sat down at a rice noodle shop and asked for a bowl of beef noodles.

"Ah Lian, can you accept it, the former me, let me come back to you......" The tape recorder on the empty table in the corner was playing Dai Jun's song. Xu You didn't leave immediately after eating the powder, he wanted to finish listening to the song. The singing voice is light and emotional, causing people to think of many things with the lyrics and rhythm - Yu Chi Li, Xu You's mind comes to mind Yu Chi Li's face, she is smiling at him. Xu You shook his head vigorously, and quickly wiped out Yu Chili's shadow from his head. He can't have feelings, children's private feelings, feelings will make him weak and kill him.

At this moment, a familiar figure flashed from the crowd on the street.

It was Li Chuang, and he left in a hurry. Xu You quickly got up and joined the crowd to follow.

Blacksmith's shop.

It's noisy inside. Bargaining, picking finished products to turn the impact of iron, blowing wind to pump coals to burn, forging woolly iron, all kinds of sounds converge and burrow into the ears.

Xu Yu stopped at the door.

Li Chuang didn't notice that he was being followed all the way, he walked into the blacksmith shop, looked around, touched, picked up and put down, squatted down and stood up, and finally chose a narrow-bladed knife with a length of 20 centimeters, which was very suitable for cutting watermelon.

With the help of the crowd, Xu You slowly approached Li Chuang - it is normal to buy a watermelon knife, and Xu You also has one, he thinks it is a bit of a fuss.

Li Chuang finished the account and walked out from the other door. Intuition told Xu You that Li Chuang was not an ordinary guard, at least unlike most of the guards he had seen, Li Chuang lacked the specific laziness of the doormen of government institutions and institutions, which instantly turned into bowing his head when he met a leader, and instantly turned into a commanding man when he met a stranger. Li Chuang has a solemn and gentle temperament.

Li Chuang's figure disappeared.

Xu You didn't follow.

"Choose a few, it's cheap, it's all good." The blacksmith who had traded with Li Chuang strongly recommended his items to Xu You, who was the boss here, "Not satisfied? You can also sample processing, you draw the drawing, as long as you can draw it, I will do it. The blacksmith dropped the hoe he was holding, confident in his craft.

Speaking of drawing drawings, Xu You's mind immediately flashed the strange device that shot Zhou Guoqiang, so he asked for paper and pen, drew an outline according to the image of the catapult that killed Zhou Guoqiang, and handed it to the blacksmith, "Just do this, okay?" ”

The blacksmith took the drawing, and when he looked at it, a panicked look immediately appeared on his face, "This...... I can't do this, I can't do it. He swallowed, didn't want to trade with Xu You anymore, and hurriedly excused himself and walked away.

Why? Xu You thought like this in his heart, if he can't do it, he won't do it, and boldly admit that it's okay, what are you nervous about.

The next day it rained heavily.

After the rain stopped, the sky did not clear up immediately. It's gloomy, and it looks like it's going to have to go on. May in the south is the rainy season, once the rain falls, it is endless, wet everywhere, everywhere is not clean, the things at home, food, clothes, furniture, if not well stored, will soon become moldy and deteriorate.

It's really a tiresome season, and Yu Chili and Xu You's thoughts are just the opposite, she feels that the weather in May is gentle and delicate, just like a woman's skin, lubricated and watery, and it will burst when blowing.

Li Xuelan's parents, siblings have rushed to school, and her daughter has also returned, and the mother and daughter have many people to comfort and take care of them, so Yu Chili has nothing to do.

She walked out of the school gate alone and went to the nearby fields to see: the river was gradually rising, slowly soaking the soil on the bank, and from the soil suddenly appeared a lot of green weeds, many flowers that could not be named, and bees were buzzing on them. The rain finally continued to fall. Falling on the tips of the hair and on the face, thin, like smoke and mist, the pond and the roofs of people's houses in the distance, densely woven like a net. "The slanting wind and drizzle do not have to return." Yu Chili walked all the way forward, and her mood slowly improved.

Now, she has time to think about some of the recent events: Wu Chang'an's death, *** poisoning, suicide or murder; Zhou Guoqiang's death was struck by an iron disc fired by a pre-installed and hidden instrument, and he was killed with one move. The Wu Zhou people she knew were polite and polite in life, and it would be hard to believe that they had a grudge against others because of something and caused them to be killed. However, the banter with Xu Yu that day has now been confirmed by the public security - they did die of murder, at least, Zhou Guoqiang's death. Man dies for money, birds die for food, if not for hatred, then for money. However, in these prosperous years, no one has a lot of savings, and the teacher's salary is not high, so he will not recruit people to rob the house.

The more she thought about it, the more chaotic she became, and Yu Chili put away her thoughts for the time being. She stood still, looked around, her eyes were full of green, and she suddenly felt much more comfortable. "Go back and ask Dad, he has been dating Uncle Wu for many years, and he must know a lot of things that I don't know."

In the evening, the rain had not stopped. Li Chuang went to Xu You's dormitory to find him and invited him to drink. His purpose was simple, to test Xu You.

Late that night, when Xu You sneaked into Wu Changan's office and secretly replaced ordinary rice paper with *** rice paper, the person who appeared at the door was Li Chuang, who witnessed the whole process of Xu You stealing beams and changing pillars. And Xu You didn't know that person was Li Chuang.

In other words, the person who killed Zhou Guoqiang was Li Chuang.

At that time, Li Chuang didn't know what Xu You had done, and he didn't have time to think about it.

Until Wu Changan's death on the day of the school anniversary, and later the Public Security Bureau reported that Wu Changan died of *** poisoning. "Oh, I see." Li Chuang was completely sure that Xu Yu had done something on the rice paper. Li Chuang thought again, why did Xu You kill Wu Changan?

Li Chuang decided to find out the ins and outs of the matter immediately, and at least, to make sure again whether Xu You knew that he had killed Zhou Guoqiang.
