When Wu Zhong arrived at the hotel, Zhao Mei was playing with her son, watching the mother and son immersed in joy, Wu Zhong's heart was full of infinite satisfaction brought by happiness. The next morning, Wu Zhong got up early in the morning and rushed to the unit, but saw Zhou Cheng who had not slept all night. As Zhou Cheng's master, Wu Zhong admires Zhou Cheng's work attitude very much, the police profession is not like other jobs with a certain regularity, overtime and staying up late are already commonplace, maybe one moment you are still sharing dinner with your family, then the next moment you may be recalled to the unit by a phone call to perform tasks, this is also a matter of no way, after all, the nature of the work is there. As a rookie who has just joined the work, Zhou Cheng's work attitude and hard-working quality are indeed worthy of cultivation by his predecessors, and Wu Zhong has no less to worry about for this.

Wu Zhong walked to Zhou Cheng's side, slapped Zhou Cheng on the back of his head, and said angrily: "How many times has Lao Tzu said, don't stay up all night if you have nothing to do, don't you know what hurts your body the most!", Wu Zhong's slap seemed to be merciless, but in fact, it didn't use much strength.

Zhou Cheng, who was in a state of selflessness, was woken up by a slap, turned around and saw the arrival of his master Wu Zhong, and immediately stood up excitedly, pointed to a pile of materials on the desk and said, "Master, come and see, what did I find!", Zhou Cheng's expression was like a child who had dug up a treasure, and he was extremely happy to show off his achievements to adults.

It turned out that Zhou Cheng stayed up all night, and he sorted out all Liu Dabiao's trajectory for nearly a year, and finally analyzed and unearthed a very suspicious clue, or his bold hypothesis. Liu Dabiao's trajectory is as follows: starting from May last year, Liu Dabiao set off from a city in S province to a city in HB province, stayed in this city for two months and then went to a city in SD province, or two months and then went to a city in JS province, and arrived at a city in ZJ province two months later, until he is now in Baishan City in province A, and the time has been nearly two months. If Liu Dabiao's identity is only a worker, it is absolutely impossible for him to travel to six provinces and cities across the country within a year, and each city only settles for two months, which is a big doubt in itself, so what is the purpose of his doing this, is it that he is hiding something, or is he looking for something.

There is a famous saying that says: make bold assumptions, reason carefully, the meaning of this sentence is simple and easy to understand, don't be afraid of how bold and exaggerated your hypothesis is, as long as its existence is likely to be realized, use careful reasoning to test it.

Zhou Cheng's bold assumption is that Liu Dabiao will be a suspect who is on the run to commit crimes, and within a year, a gang that spans half of China's six provinces and cities, will step on the spot to find the target within two months in each city, and will not stop after succeeding and immediately transfer to the next province to continue the crime. Around this idea, the second middle school began to study again, they called up the bill situation of the first five cities, after a lot of screening, found some clues, and finally locked a gang of burglary and robbery, this gang has a strong sense of anti-reconnaissance, and the location of each crime is very clever to avoid the monitoring range, and the time of the crime is also selected at two in the morning. Around three o'clock, usually this time period is the deepest time for people to rest, if the victim is found out during the crime, the suspect will immediately use violence to control or knock the victim unconscious. After ransacking the victim's home, they took advantage of the darkness and blind spots of surveillance to escape, leaving few valuable clues at the scene. Every time this gang goes to a city, it will frantically commit more than a dozen crimes overnight and disappear without a trace, and it is very rare to be skillful in modus operandi, strong in anti-investigation, and arrogant in arrogance. Judging from Liu Dabiao's behavior trajectory, it is very consistent with this rampant theft gang, but there are still many details that need to be scrutinized.

"Ah Cheng, the brother units of several cities, are there any photos of this group of people?"

"No, it's all face-covering," Zhou Cheng replied.

"What about the surveillance footage?" Wu Zhong said calmly.

Zhou Cheng quickly handed a pile of materials to Wu Zhong and said, "There is a ......."

In the afternoon of the same day, Wu Zhong and Zhou Cheng reported the entire case to the higher-level leaders, including their master and apprentice's inferences and ideas, and after intense and orderly work arrangements, two days later, the members of the special case team successfully cracked this theft gang that had spread throughout the country, and all nine gang members except Liu Dabiao were arrested. As for Liu Dabiao, he should have been arrested together, probably his luck was extremely good, at the moment before the implementation of the arrest plan, Liu Dabiao went to the toilet with stomach discomfort, and saw the police in action from the window on the way, and the frightened Liu Dabiao hurriedly did not have time to report to his accomplices, so he climbed out of the window and jumped from the second floor to escape the catastrophe, for which the police sent a lot of police force.

Liu Dabiao's father died in a car accident before he was born, and he lived with the Li family since he was a child, and the orphans and widows were also very pitiful. Liu Dabiao's mother, Li, was vicious and very spicy, and everyone in the township knew her temperament, and no one was willing to provoke her, so that several hooligans in the nearby township did not dare to bully her. After Liu Dabiao's father died, Li received a sum of compensation, and she took all the money to open a commissary. It's a pity that the good times didn't last long, when Liu Dabiao was a teenager, Li suddenly fell seriously ill, and after spending all the family's savings, he didn't cure the disease, and then Li had to stay in bed all the year round, and only the teenage Liu Dabiao took care of her at home. Liu Dabiao, who dropped out of school and stayed at home, did not know any life skills at all, and he was thin and weak at that time, and could not engage in manual labor, in order to buy medicine for his mother to treat his illness, and also to have money to buy rice to fill his stomach, Liu Dabiao, who was forced by life, began to steal a lifestyle. At the beginning of the period, he only dared to steal scrap iron and firewood in other villages to exchange for food, and later he became notorious for his unclean hands and feet, and everyone avoided him. Sometimes Liu Dabiao's "harvest" is good, and he can last for a few days, sometimes he is caught and beaten, and then silently returns home to endure hunger, even then he will not let his mother Li go hungry, and the family will always have Li's rations. Liu Dabiao is a filial son, after all the stolen things are exchanged for money, he immediately goes to buy medicine for his mother Li, and the rest is to buy some dry food, he never takes money to spend indiscriminately, even if this money sometimes comes so easily. Before the teenage child has not formed an outlook on life and has no concept of good and evil, the law of the law of the jungle and unscrupulous means is engraved in his heart early. In his heart, no one is so important except his mother, Lee.

A month later, Liu Dabiao, who had been in hiding, finally absconded back to his hometown of a village in S Province after a lot of hardships, where his mother Li, who was more than 50 years old, lived in a two-room earthen house. Liu Dabiao hid in the woods and watched his home, at this time Wu Zhong and four or five plainclothes policemen were visiting his home, Liu Dabiao knew Wu Zhong, it was he who led a large group of policemen to copy their gang, and he was very impressed by this person. The frightened Liu Dabiao knew that the police had found his home and wanted to arrest him, but he was not worried about his mother Li at home, so he had to patiently hide in a hidden place and observe. More than an hour later, only to hear the sound of the ambulance from far and near, and finally stopped at the door of Liu Dabiao's house, the villagers who rushed to the scene crowded around the ambulance to look into the house, Liu Dabiao hid in the distance and did not know what happened, after a few weeks, the ambulance drove away, and the onlookers gradually dispersed, at this time it was dark, Liu Dabiao dared to take advantage of the night to enter the house......

The reason why the police are so anxious to find Liu Dabiao is mainly because a certain member of this theft gang reported to the police a major crime of the leader of the gang, Zhang, according to the informant, he heard Liu Dabiao say after drinking one night a year ago: Once Liu Dabiao was anxious to use money to buy medicine for his mother to treat her illness, but the wind was very tight at that time, and the gang had not committed a crime for more than a month, just to avoid the limelight. In desperation, Liu Dabiao decided to secretly go alone, at more than 2 o'clock in the morning, Liu Dabiao went out to commit crimes, when he returned to the den before 4 o'clock, he happened to see the head Zhang in the grove behind the den, Liu Dabiao saw Zhang sneakily carrying a sack to the back mountain, so he quietly followed behind, and found that Zhang was actually burying the body! Liu Dabiao, who was frightened, held his breath and did not dare to make a sound at all, and did not dare to return to the den until Zhang left. Liu Dabiao, who was urged by curiosity, originally wanted to find a time to go to the place where Zhang's body was buried, but the next morning Zhang suddenly announced that he was going to transfer the den, and Zhang used the excuse that 'this place has been exposed', only Liu Dabiao guessed in his heart that the real reason for the transfer of the den may be related to the corpse. After the police got this clue, they immediately sent people to the grove mentioned by the informant, but the scale of this so-called grove is actually very large, and the police want to find the location of the burial in such a large piece of wood, and the difficulty can be imagined. At the same time, the police interrogated Zhang, and the cunning and abnormal Zhang took advantage of the fact that the police did not have direct evidence, so he bit his tongue and refused to admit the crime, so the task force intensified its work and patience to find the witness Liu Dabiao.

It is often said that 'seeing is believing, hearing is false', but does what you see have to be true?

Half a month later, Liu Dabiao quietly sneaked back to Baishan City, Province A......

At this time, Wu Zhong was still taking care of Liu Dabiao's mother in the hospital, and the original plan of the task force was for Wu Zhong to take people to Liu Dabiao's house to do ideological work to persuade his family to vote, and if conditions permitted, he could arrange for plainclothes to squat near his home for a few days. Wu Zhong first learned about Liu Dabiao's family situation from the village cadres, and learned that Liu Dabiao's mother, Li, was tired all year round, and finally caused her to be sick in bed, and Liu Dabiao had to support her family secretly when her family was poor. As a filial son, Wu Zhong was very sympathetic to Li's suffering, and felt pity for the human tragedy that the current situation of a family directly led Liu Dabiao astray, and finally Wu Zhong bought a lot of nutritional products out of his own pocket to visit Li.
