In court, when Bai Xiaoli was charged with intentional injury and stood in the dock, lawyer Chen Haoming behaved very calmly, and he used his professional knowledge and strong arguments and arguments to win the lawsuit with ease. When the judge solemnly announced the result of the trial, Bai Xiaoli was acquitted and released from court, Bai Xiaoli looked at Chen Haoming with gratitude and admiration, and Chen Haoming also smiled at Bai Xiaoli.

The next day, Bai Xiaoli suddenly disappeared.

Zeng Lei, a criminal policeman who has just joined the work for more than a year, is bent on solving big cases. After receiving a clue from a gangster, who is also his informant nickname "Da Long", he follows A Qiu, the lover of a drug suspect Du Wei, day and night, waiting for an opportunity to arrest Du Wei.

Zeng Lei, who graduated from the Criminal Police Academy, is smart, clever, and good at using his brain, and he is sensitive to detect Ah Qiu's suspicion. He found that Ah Qiu's daily expenses were very large, and the places he went in and out every day were only shopping malls, restaurants, beauty salons, nightclubs and other places, which made Zeng Lei's suspicion of Ah Qiu even heavier.

He talked to Ah Qiu back to the criminal police team several times, and Ah Qiu didn't say that he won money from playing mahjong, but that it was left to her by her previous boyfriend. As for her former boyfriend, she can't even name her real name. In short, she refused to give an account of the true source of her property. Zeng Lei understands that drug abuse is a serious crime in our country, and as long as he embarks on this road of drug abuse, it is impossible to turn back or admit it willingly. In desperation, he had no choice but to continue to wait for the rabbit.

The criminal police team has a new case for Zeng Lei, but he doesn't want to take it, first, he doesn't want to give up the line of Aqiu, he is eager to solve the big case, not to mention the eyebrows, and the most important thing is to have a sense of achievement. The second is the new case given to him by the team, which is a case of wounding, and he suspects that the case is small, and he feels that it is far less enjoyable than the feeling of arresting the drug suspect Du Wei. But due to the rules and orders of the team, he had to take it again.

So, he secretly asked his informant Da Long to follow Ah Qiu for him. Every night at 9:10, he and the informant Da Long would meet at the back door of a small bar, and Da Long would tell him about Ah Qiu's daily whereabouts. For example, when and where you met someone, or what you did. As for whether there is an abnormality, it is up to Zeng Lei to judge.

The first and second days were all fine, and on the evening of the third day, Zeng Lei was at the "joint" they had agreed on, without waiting for the appearance of Dalong. This night, Zeng Lei couldn't sleep all night. He wanted to go to the place where Dalong frequented him, but he was afraid that he would be startled by it. So, he guessed that Dalong might have fallen asleep after drinking too much, and maybe he would come the next night.

As a result, the next day, at the back door of the small bar where Zeng Lei and Da Long had made an appointment to meet, people found Da Long's body. The corpse was packed in a woven bag with red, white and blue stripes, and Dalong's body was badly damaged and his face was horrible. Obviously, the back door of the small bar was not the scene of the first crime, and the body was specially transported after death. The murderer's original intention can be seen, he must have discovered the "secret" of Zeng Lei and Dalong, so he chose to kill people.

Zeng Lei fell into confusion, pain, and deep self-blame. "It's me who wants to investigate Ah Qiu, it's I who want to arrest Du Wei, I want to solve the case, why don't I go myself, but let Dalong do it for me? If I do this, I will let him die for me! Damn it's not the dragon, it's me! Zeng Lei knelt in front of Dalong's corpse, hiding his face and crying.

The leaders of the criminal police team were very dissatisfied with Zeng Lei when they knew about this incident, saying that he did not follow the rules and did not obey the order to investigate the case privately, so that others died in vain. The team made a decision to punish him, deducted his bonus for one year, and wrote an examination. The captain also specially emphasized to him: "The examination should be profound, at least 10,000 words." Zeng Lei responded with a sneer.
