Maybe it's because there haven't been guests at home for a long time, maybe it's because of the stimulation of alcohol, maybe it's because Xu Lang and his grandson Yu Hongxuan are of the same age, today's Yu Zhen is very talkative, the old man who usually only drinks one glass of medicinal wine alone, today he drank two glasses for the first time, and the dishes on the table were added and added, he watched Xu Lang keep talking about medical things, and Xu Lang has been listening silently beside him.

After eating this meal for more than two hours, Yu Zhen was also drunk and was helped into his bedroom by Xu Lang and Zhao Hua to rest.

After Xu Lang arranged for the old man to lie down, he looked around Yu Zhen's room.

The old man's room is very simple, a big wooden bed, a large wardrobe, and some other bits and pieces are placed in the room, in addition, on the bedside table, Xu Lang saw a table, on which is a family portrait of a family of four, the photo is a black and white photo, it has begun to yellow, it seems that it is an old photo of some years.

In the photo, Yu Zhen is still relatively young, although his hair has turned gray, but his body is not rickety, and he does not have crutches in his hands.

There was also a boy about seven or eight years old sitting on Yu Zhen's lap, the boy's eyes were very bright, he smiled very happily, and there was a shallow dimple on his face, the boy looked very delicate and cute, if he didn't have a flat head, it was easy to think of him as a girl.

Standing on both sides of Yu Zhen's back, there was Xu Lang and the woman they had seen, Lu Qinxuan, Lu Qinxuan was still very thin at that time, not as plump as she is now, she was also very beautiful and delicate when she was young, her hands were tightly holding a man's arm, smiling very happily and happily, her eyes were full of sweetness, the man's right hand was in his pocket, and the other hand was on the back of the chair where Yu Zhen was sitting, although the man did not smile, but the expression on his face was very warm, the man was wearing a pair of glasses, It looks like it should be glasses with high myopia.

This is a family portrait that looks very happy and happy, three generations in the same house, for the man in the photo, it should be Yu Tian, who has been dead for seventeen years, Xu Lang looked at the man, and finally put his eyes on the boy sitting on Yu Zhen's lap, Xu Lang looked at the photo of the boy, and had to admit that the boy was really beautiful, yes, that's right, it was beautiful, beautiful like a girl, which made Xu Lang feel a little weird.

Just as Xu Lang was watching with the table, a woman's voice came from behind them.

"It was a photo taken 19 years ago, and it was specially taken on my father's 60th birthday."

Xu Lang turned around with the table, looked at the woman standing at the door, one hand on the door frame, Xu Lang smiled slightly, turned around and carefully put the table on the bedside table, and then, Xu Lang walked out of Yu Zhen's bedroom with Zhao Hua, and after closing the door, Xu Lang said to Lu Qinxuan: "Can you take me to your son's room to have a look?" ”

Originally, Xu Lang thought that Lu Qinxuan would refuse, but what he didn't expect was that Lu Qinxuan only hesitated a little and nodded in agreement.

Yu Zhen's home is a three-story building, the old man Yu Zhen lives on the second floor, Lu Qinxuan lives on the first floor because of his inconvenient legs, and Yu Hongxuan's bedroom is on the third floor, the third floor is much smaller than the second floor, there is only a locked bedroom and study, Lu Qinxuan held on to the handrail of the stairs, limped with Xu Lang and they came to the third floor, took out the key and opened the door of Yu Hongxuan's bedroom.

When the room was opened, Xu Lang didn't smell any musty smell, after Xu Lang walked in, he saw that the room was neatly tied, a single bed, the mattress sheets were stacked neatly, and there was a desk next to the window, and there was a pen holder on the desk, several books related to medicine, these books were neatly placed, and in addition, there were several thick notebooks on one side of the desk.

Xu Lang walked over, first picked up the book as thick as a brick and flipped through it at will, Xu Lang found that many places on the book were written on it with different colored pens, many of which were some relevant annotations, it seems that Yu Hongxuan is indeed very interested and obsessed with medicine, Xu Lang turned a few pages, put the book back in its place, and then picked up the notebook and looked at it, and found that the thick notes were also densely written on a lot of notes, which contained a lot of special terms and some formula codes related to medicine, Xu Lang is not very familiar with medicine, so he doesn't understand it very well, so, after Xu Lang looked at it a few times, he put it back into the distance, just when Xu Lang put down the notebook, he suddenly found that at the bottom of the notebook, there was a book, it was a detective, Xu Lang pulled out from under the notebook, flipped through it, Xu Lang found that the book was very badly worn, it should be caused by someone reading it often, in addition, there are many places in the book that have been marked, these places have been marked, It's all about the details of how the murderer carefully disposes of the body after killing someone.

Xu Lang read the book from beginning to end, and then quietly put it back into the distance, and then looked around the room, Xu Lang found that the room was very simple, except for the bed and desk, that is, in the cabinet where clothes were placed, there were no posters or some sports tools such as football and basketball like other children, and there were no cartoon dolls or the like, clean, very clean.

Xu Lang walked to the side of the wardrobe and opened the wardrobe to take a look, Xu Lang found that Yu Hongxuan's clothes are also very simple, only white and black two colors, among them, black is the majority, in addition to these two colors of clothes, Xu Lang did not see any other color, in addition, Xu Lang also found a small detail, that is, no matter what kind of clothes, they are black and white, Xu Lang looked at the clothes in the wardrobe and asked: "Are all his clothes selected by you?" ”

Lu Qinxuan glanced at the inside of the closet, shook his head, and said, "Since his father's accident, he has bought everything by himself. ”

"Don't you think it's strange that he only buys black and white clothes? And buy two sets of the same style? Xu Lang asked as if chattering.

Lu Qinxuan shook his head with a wry smile and said, "Strange, how can it not be strange?" Before, his grandfather asked him why he did this, he said that he likes black and white, white will give people a feeling of sunshine and cleanliness, black can make him feel safe, his grandfather has also tried to buy him other colors of clothes before, but, every time after buying, he is very angry, saying that he is not willing to wear anything, over time, we are not reluctant, after all, his father is no longer there, I have become the way I am now, hey"

Lu Qinxuan sighed deeply when he said this.

Xu Lang fully understood Lu Qinxuan's mood, he didn't continue to ask anything, he closed the closet, looked around again, and then left the room with Zhao Hua, after that, they asked Lu Qinxuan about some things about Hongxuan, although Lu Qinxuan was Yu Hongxuan's mother, but she didn't know much, Xu Lang and they couldn't find any results, so they said goodbye and left.

When Xu Lang and Zhao Hua left, they walked on the muddy dirt road, and after the two of them walked for a distance, Xu Lang subconsciously stopped and looked back at the house, and found that Lu Qinxuan was still standing at the door, looking at them from a distance, because the distance was too far, Xu Lang couldn't see Lu Qinxuan's expression clearly, but Lu Qinxuan's slightly narrowed eyes and the light emitted, Xu Lang could still feel it.

"Brother Lang, what are you looking at?" Zhao Hua saw that Xu Lang had stopped, so he also stopped, turned his head, glanced at Yu Zhen's home, and then looked at Xu Lang and asked.

Xu Lang smiled and waved at Lu Qinxuan, Lu Qinxuan also waved at Xu Lang, and then turned around and put it back at home.

After Lu Qinxuan completely entered the house, Xu Lang's face, which was originally full of smiles, suddenly became gloomy, and he said slowly: "There is something wrong with this Lu Qinxuan." ”

"Lu Qinxuan has a problem? What's the problem? Why didn't I see it? Zhao Hua asked with a puzzled expression.

Xu Lang turned around and continued walking, saying as he walked, "Lu Qinxuan's leg is fine. ”

Zhao Hua was stunned for a moment, then looked at Xu Lang in disbelief and asked, "You mean to say that her limping walking posture was pretended by her?" ”

Xu Lang didn't speak, but nodded.

Zhao Hua didn't believe it at first, and felt that it was impossible, if Lu Qinxuan's leg was fine, then why did she pretend to be lame? However, although Zhao Hua didn't quite believe that this was the truth, Xu Lang would never say something that he was not sure of, and besides, Xu Lang said it so surely, Zhao Hua asked, "How did you see it?" ”

Xu Lang said lightly: "Although the current medicine is very developed, it is not a big problem to let a person who has been paralyzed for many years stand up again, as long as he has an operation and recovers well, it can still be done, but, have you noticed that Lu Qinxuan's leg has not atrophied." ”

Hearing Xu Lang ask, Zhao Hua nodded subconsciously, Lu Qinxuan's legs did not atrophy, Zhao Hua couldn't understand why Xu Lang asked this, is there something strange in this, he looked at Xu Lang with a puzzled face.

Xu Lang saw Zhao Hua's expression, and explained with a smile: "Lu Qinxuan was paralyzed in the car accident seventeen years ago, it stands to reason that a person who has been paralyzed in bed for many years, even if her family takes good care of her, it is understandable that she has no hemorrhoids, after all, Yu Zhen is a doctor, and she herself is a nurse, but if she is bedridden in the longevity area and does not exercise, even if she takes care of her well, her muscles will atrophy, but you should have seen it, Lu Qinxuan's legs are no different from normal people, not only have they atrophied, And there are also strong muscles. ”

After Xu Lang's analysis, Zhao Hua remembered the situation when he saw Lu Qinxuan just now, when Lu Qinxuan came out of the kitchen, his legs were limping, but Lu Qinxuan's legs were indeed the same as Xu Lang said, there was no atrophy, and he walked very strongly.

Xu Lang continued: "Generally, people with leg disabilities, especially those who are limping, their legs will be long and short, but Lu Qinxuan does not, and people with leg disabilities will wear out their pants and shoes, and the wear and tear on both sides will be different, but have you seen Lu Qinxuan's shoes and pants?" ”

"The wear on both sides is the same, almost, it seems that she is indeed pretending to be lame." Zhao Hua suddenly realized.

Xu Lang nodded, another point is that a person with a real leg disability, when they walk, they will be the same as normal people, they will not care about their walking posture and movements, it is normal for their feet to be deep and shallow to move, but Lu Qinxuan is different, every step of her is exactly the same, it is obvious that it can be hidden and disguised.

"Why would she pretend she's disabled?" Zhao Hua asked puzzled.

The question asked by Zhao Hua is also the answer that Xu Lang wants to know, why? He couldn't figure it out either.

After Xu Lang pondered for a moment, he said to Zhao Hua: "After you go back, you go and check Lu Qinxuan's hospitalization records after the car accident to see if she is really paralyzed or pretending to be paralyzed." ”

Zhao Hua nodded when he heard this, he knew what Xu Lang was suspicious of, and now he could only do so.

After the two of them walked out for a distance, Zhao Hua asked again, "Brother Lang, did you find anything wrong?" ”

Xu Lang didn't rush to answer Zhao Hua's question, but asked rhetorically, "Did you find anything wrong?" ”

Zhao Hua thought for a while and said: "First, Yu Hongxuan's bedroom is too clean, Yu Hongxuan hasn't come back for seven years, it stands to reason that it can't be so clean and tidy, the flyers and bedding are all new, which is too unusual, second, Yu Hongxuan actually only has two colors of clothes, although he is a boy, men's clothes are not so particular, but a person always wears only two colors of clothes, and it is the same clothes, which is also very unusual, third, in their home, Except for a very old photo in the old man's bedroom, there is not a single photo, not only is there not an old man's, nor Lu Qinxuan's, nor is there a photo of Yu Hongxuan, which is very abnormal. ”

Xu Lang listened to the three points that Zhao Hua said, Xu Lang nodded, it seems that Zhao Hua is worthy of being an investigator, and his observation is still very subtle, Xu Lang noticed what he said, but Xu Lang also noticed one thing, that is, the detective book on Yu Hongxuan's desk, which is a book that tells in detail how criminals should commit crimes perfectly, although it is, most of the content is apocryphal, but some of the criminal methods in it are still real, as for why Xu Lang knows this, That's because Xu Lang also has this book, and it is a collector's edition, so when he saw the title of the book, he knew the content inside.

Xu Lang can deduce from the books that Yu Hongxuan put on the table and his notebook that Yu Hongxuan is indeed a person who is very obsessed with medicine, and he must be very talented in this regard, but the more this is the case, the more Xu Lang suspects him, for no other reason, that is, after Jin Enpei was killed, the incision surface of the corpse wound was made by a person who knows the structure of the human body very well, so whether Jin Enpei was killed by Yu Hongxuan?

Wu Yong told Xu Lang that Yu Hongxuan did not go abroad seven years ago, but was still in China, so where is he now? Is it in S or T? Or in other cities? None of this is known.

Now, Xu Lang has begun to contact Yu Zhen and Lu Qinxuan, since Xu Lang has discovered that Lu Qinxuan is pretending to be lame, then, what we have to investigate now is seventeen years ago, after the car accident, was Lu Qinxuan really paralyzed, and if Lu Qinxuan was really paralyzed, then when did she recover? If she wasn't paralyzed, then why was she pretending to be paralyzed at the time? And this pretense is seventeen years? There must be something hidden in this, and Xu Lang and they must investigate it clearly.

In this way, after the two of them returned to the guest house, Zhao Hua left the guest house and went to investigate Lu Qinxuan as Xu Lang instructed, and Xu Lang returned to the room alone.

Xu Lang was standing by the window, he was pondering, thinking about things, Xu Lang was not thinking about Jin Enpei's case, nor Lu Qinxuan's purpose of disguising himself, let alone where Yu Hongxuan was now, but remembering that Yu Zhen inadvertently mentioned that he had seen a person very similar to Xu Lang more than twenty years ago after he got drunk.

Twenty-three years ago, Xu Lang was only about three years old, Yu Zhen couldn't know what he would be like when he grew up, then, at that time, what Yu Zhen saw must be his father Xu Yuan, and Yu Zhen also told Xu Lang that he went to S City to have a major operation, although Yu Zhen did not say who to operate on or what to do, but Xu Lang can be sure that Yu Zhen, as a famous surgeon in T City, asked him to go from T City to S City to have surgery, it must be a very tricky operation, so what kind of operation is it together? What will be the outcome of the surgery? Why was my father there? Could it be that Yu Zhen was operating on a police officer within the public security system at that time?

Xu Lang felt that this was very likely, if it was an ordinary operation, the medical staff in S City would definitely be able to complete it, so if Yu Zhen was invited over for surgery, it must be an operation on an important person, so who would it be? Xu Lang didn't know, at that time, he didn't want to ask Yu Zhen, it's just that Yu Zhen just mentioned it so casually, after saying this, he changed the topic, and Xu Lang came for Jin Enpei's case, it's inconvenient to ask so much, as the saying goes, Yu Zhen is an old man who is nearly eighty years old, an out-and-out old fox, he has eaten more salt than Xu Lang has eaten rice, as long as Xu Lang shows a little flaw, it will definitely attract the attention of the old guy, if this is the case, Xu Lang will be very passive at that time, so he couldn't help but not ask at that time.
