On the way back, Xu Lang told Wu Liang to ask the people from the technical department to do a paternity test for the dead child, Zhou Yongli, Wu Gai and Wu Jiu.

For Xu Lang's suggestion, Wu Liang naturally knew.

The police car stopped in front of Xu Lang's house, Xiao Yueyue took the lead in pushing open the back door and getting out of the car, while Xu Lang sat in the co-pilot, looked at Wu Liang and said, "After I go back, I will also do a paternity test for Wu Jiu's child." ”

Wu Liang looked at Xu Lang with a puzzled expression and asked, "Why?" Did you find something? ”

Xu Lang shook his head, "I just have a guess, you just have to do what I say, and when the results come out, you will know." ”

Wu Liang glanced at Xu Lang deeply, and then nodded, his eyes were a little complicated.

Xu Lang didn't seem to notice Wu Liang's expression, and he continued: "Carefully ask about the relationship between these two families and seven people, there may be unexpected gains, this is not a simple murder case. ”

Wu Liang was more and more confused by Xu Lang's words, he didn't understand why Xu Lang emphasized this point, but when he saw Xu Lang after saying this, he pushed open the co-pilot's door, and after getting out of the car, he knew that Xu Lang didn't give him a chance to ask questions, obviously he didn't want to tell him his inner guess, Wu Liang didn't feel anything strange about this result, after all, in the past few years, Xu Lang has been like this every time, Wu Liang just needs to do what Xu Lang said, There will be unexpected discoveries, which will bring great help to the detection of the case, even if there is no practical help at the beginning, but every time they get into the quagmire at the end of the case detection, what Xu Lang asked him to do before will play a key role, so Wu Liang has an unreasonable trust and worship for Xu Lang.

After seeing Xu Lang get out of the car, he had already taken out the key to open the door of the house, and after taking Xiao Yueyue in, Wu Liang did not stop here any longer, started the car and drove towards the public security bureau, after all, there are still many things he needs to do, moreover, today is the Chinese New Year's Eve, many police officers are on vacation, the manpower is already insufficient, if he does not rush back early, in the face of three corpses, five injured and suspects, there may be some mistakes.

On the way back, Wu Liang kept thinking, what did Xu Lang ask him to do a personal appraisal of Wu Jiu's child, the cause of this case was because of the gossip of the villagers, suspecting that Zhou Yongli's child was born to Liu Xiaocui and Wu Gai, which caused the murder, logically speaking, as long as the child who was killed by Liu Xiaocui fell to death, what is the use of doing a personal appraisal for Wu Jiu's child?

Thinking of this, Wu Liang remembered the forensic doctor's preliminary judgment on the cause of Wu Gai's death, as well as the testimony of the neighbors at the time, Wu Gai died after drinking the poisoned wine poured by his daughter-in-law Li Hongmei, if it was really a murder caused by gossip, Li Hongmei should stand with Wu Jiu's family, she should have no motive for committing the crime, it is rumored that Liu Xiaocui has an improper relationship with her husband Wu Gai, not her husband Wu Jiu, what is the purpose of her doing this?

Is it because she and Liu Xiaocui are cousins?

Wu Liang shook his head, thinking it was unlikely, not to mention that they were just cousins, not sisters, just because she was Wu Jiu's daughter-in-law and Wu Gai's daughter-in-law, she had no motive to commit the crime.

Wu Liang thought of this, and felt that things were a little unreasonable, and he thought that when Xu Lang was about to get out of the car, he asked himself to inquire about the relationship between the five people who survived, and said that there was an unexpected gain, so what would this unexpected gain be? Isn't it a neighborly relationship? Husband and wife? Cousin relationship? Wu Liang couldn't figure out what else was related to them.

Because he couldn't figure it out, Wu Liang remembered the man with dazzling white hair, Xu Lang.

For Xu Lang, Wu Liang's attitude has always been very complicated, first, he was amazed by Xu Lang's intuition and judgment in many cases, that keen intuition, logical clarity and rigorous reasoning, Wu Liang has always wanted to learn but can't learn anything, second, he feels that Xu Lang is a man with a story, a very dangerous man.

Xu Lang came to this small county five years ago, his appearance was so sudden, and he also brought a small baby, these years, Xu Lang has been alone to raise Xiao Yueyue from a nursing baby to a child who has begun to go to school, in five years, Xu Lang has never left Zhuxi County, nor has he looked for a job, but he seems to have endless money, although Xu Lang's home does not look very rich, but, for Wu Liang, who is already married, he knows, How much does it cost for a man to live with a child?

What if the child is small and needs to be fed, and there is no woman around? can only eat milk powder, and Wu Liang has long noticed that when Xu Lang was young in Xiao Yueyue, the milk powder he bought for her was the best and most expensive, and a can cost hundreds of yuan, which is a big burden for an ordinary family, but Xu Lang did not, the child grew up, and the degree of food and clothing needed to be updated as the child grew up, which required a lot of money, in addition, Wu Liang often went to Xu Lang's house to eat, and he found that the meals Xu Lang made for Xiao Yueyue were very nutritious and looked ordinary, but, In terms of price, it is not affordable for ordinary families.

These all need money, and Xu Lang has no job, no work, and no financial resources, so where does he get all this money from? Wu Liang has always been very curious, he once asked Xu Lang in a joking tone, but Xu Lang at that time just let him drink and didn't explain anything.

Wu Liang didn't suspect Xu Lang, whether he was a robber, or did something shady behind his back, but, in the past five years, he didn't find that Xu Lang had done anything illegal and undisciplined, he and Xiao Yueyue were like an ordinary family, Wu Liang once took Xu Lang's ID card, investigated Xu Lang's information within the public security system, and did not find that Xu Lang had a criminal record before, Xu Lang's information was very clean, only knew that he was from S City, H Province, a coastal city in Huaxia Kingdom, As for more information, no.

There is another thing that makes Wu Liang feel very strange, he found that Xu Lang's marital status is not married, nor divorced, let alone widowed, but unmarried, not married, how can he have children? Although young people in today's society, unlike the older generation, have children after marriage, today's young people, happy together, have a relationship, and do not pay attention to protective measures, in case of pregnancy, so many hospitals, it doesn't cost much to do an abortion, many young people do this, do not know how to take care of their bodies, even if they have to get pregnant, there are too many girls, after giving birth, either give the child away, or abandon the child, or even directly to death, This kind of thing happened not once or twice, but many times, and Wu Liang had handled several similar cases.

However, Xu Lang is already a thirty-one-year-old man, and he will be a thirty-two-year-old man after the New Year, he is four or five years older than Wu Liang, Wu Liang himself will not do that, with his current understanding of Xu Lang, he knows that Xu Lang is not the kind of irresponsible man, so he feels strange.

Wu Liang couldn't see through Xu Lang, he often went to Xu Lang, in addition to these things because of the case, he was more likely to test Xu Lang, and Xu Lang knew this, but he didn't say it, but, five years have passed, except that he knows that Xu Lang has cooperated with the police many times in S City, he has not tried anything else, which makes Wu Liang very depressed.

And today, there are two things that make Wu Liang feel even more incredible, one of which is related to Xu Lang, that is, when they arrived at the scene, when there was about to be a fight, Xu Lang easily took the gun from his body, and fired a shot, at that time, when Xu Lang fired, Wu Liang keenly found that Xu Lang's hand that fired the gun did not tremble at all, it was so steady, at a glance, I knew that Xu Lang had touched the gun before, and the technique was very good, this was the first time Wu Liang found out, also made him feel that Xu Lang was really dangerous.
