Rebirth 78, the beginning of the marriage was broken off by the female educated youth

"I didn't recognize the voices of several people!"

Wei Jingfei shook his head, but immediately said, "It was a very quiet night. The prisoner said it was around ten o'clock when he heard soft voices from next door... He had arthritis and his legs hurt at night, so he slept lightly. He heard some noise in a daze, but when he listened carefully, it was gone quickly!"

"How long did it last?" Li Xiangnan asked with a frown.

"He doesn't understand it either. He thinks he's hallucinating..." Wei Jingfei pondered, "But I don't think it will last too long. Otherwise, he wouldn't think he's hallucinating. Isn't it just an occasional shudder? If it lasts longer, he might wake up and listen for a while..."

It is indeed possible.

Wei Jingfei immediately followed up, "If there were voices, then there must be more than just Xu Sheng."

Li Xiangnan didn't rush to answer.

If Xu Sheng had mental problems, it was possible that he was talking to himself or talking nonsense.

But according to the information we received earlier, Xu Sheng's mental state is normal.

In other words, there was indeed a second person in his room last night.

There was another person in his cell last night.

"Besides that!" Wei Jingfei reminded, "Advisor Li, a supervisor said he smelled a strange odor while on patrol last night, like something burning..."

"Oh?" Li Xiangnan narrowed his eyes. "What time?"

"Nine o'clock!"

"Nine?"

"Hmm!" Wei Jingfei continued, "He felt like something was burning, but when he hurriedly searched the corridors and cells, the smell disappeared. It was very faint and fleeting. He searched for more than half an hour, but there was no movement in the cells, so he went back!"

Li Xiangnan raised his eyebrows: "Has he been to Xu Sheng's cell?"

"I have been there. He asked Xu Sheng if he was okay, and he replied that he was fine!"

In other words, before 9:30 last night, Xu Sheng was at least still alive.

So the time of his death was between 9:30 and 1:00 in the morning!

Li Xiangnan noted this time point.

At this time, the door of the heavy-duty prison area suddenly opened, and a middle-aged man in his forties hurried into the corridor and ran towards the library. He happened to run past the two of them and looked at them with confusion.

Li Xiangnan noticed that the man's eyes were full of panic, as if something bad had happened and bad luck was about to happen. The buttons on his clothes were all wrong, and he was in a completely dazed state, as if he had been suddenly woken up from his sleep.

"Shi Jian!"

"District Chief Cheng!"

Two shouts were heard from inside, and Li Xiangnan then realized that the person was District Chief Cheng whom they had been waiting for.

Cheng Sanmin, the district chief of the heavy criminal detention area.

"Ask Xiao He to come over and make a copy of the recent book borrowing records!" Li Xiangnan glanced at Wei Jingfei, who understood and left quickly.

Shi Yang had already walked over quickly with Cheng Sanmin, introducing him: "Advisor Li, this is District Three Chief Cheng Sanmin! District Chief Cheng, this is Li Xiangnan, the Criminal Investigation Consultant of the Municipal Public Security Bureau!"

"Ah... hello, hello!" Cheng Sanmin called out first, then his face turned pale and he quickly said, "I've heard a lot about you!"

Li Xiangnan's name is now not only well-known in the medical community of Yanjing, but also a terrifying presence in the police station.

There is no prison nearby that is unaware of what happened in Qincheng Prison.

"District Chief Cheng!" After exchanging greetings, Li Xiangnan didn't exchange any pleasantries and asked directly, "Are you familiar with this book? May I ask who lent it to Xu Sheng?"

"Huh?" By the time Cheng Sanmin realized what was happening, Shi Yang had already taken the child psychology book from Li Xiangnan and handed it to him. He looked down, puzzled, "This book... I borrowed it for Xu Sheng. What's wrong, Consultant Li?"

Li Xiangnan nodded, turned the page, pointed at the Chinese characters with horizontal lines, and asked, "Did you draw these characters?"

When he asked this question, he stared at the other person closely, afraid of missing any subtle expression on his face.

But Cheng Sanmin quickly shook his head: "No, it's not me! I'm not interested in this book at all. I usually only read novels, like Officialdom Unmasked."

"Then why did you write Xu Sheng's name on the book you borrowed?" Li Xiangnan asked again, "Is there any special reason for doing so?"

"There are many serious criminals in our prison area. Generally, if someone needs a book, I will help them borrow it. Sometimes there are too many books and I can't remember the title, so I can only write the borrower's name directly to make it easier to find it later!"

As soon as these words were spoken, Shi Yang and the librarian in front of him all breathed a sigh of relief.

That's it!

Li Xiangnan looked at Cheng Sanmin for a long time and nodded slightly.

The reason is valid and very reasonable.

He walked to the front desk, took out the original records from the police officer Xiao He, and flipped through the records back to three months ago. There was no borrowing record of the psychology book, except that Xu Sheng had borrowed it once two days ago.

As if guessing what Li Xiangnan was looking for, Cheng Sanmin said nervously, "Advisor Li, only books that have been borrowed are registered. If you're reading in the reading room, you don't need to register. You can retrieve or change them at will... Did you find something in this book?"

Li Xiangnan naturally wouldn't answer his question, so he shook his head and said, "Thank you, District Chief Cheng!"

"We don't want this form anymore. You don't need to copy it. Just take it away. I'll get a new one!" The librarian on the side quickly expressed his attitude to the police officer Xiao He, in a very humble manner.

Xiao He looked up at Li Xiangnan, and after getting a nod, he stood up and handed the watch to Li Xiangnan.

"District Chief Cheng, please go and take a statement with Comrade Xiao He. Sorry for taking up your time!"

Cheng Sanmin was stunned, his face looked ugly for two seconds, but he nodded, said nothing, and followed him out.

"Advisor Li, I have arranged an office for the public security comrades to rest. I will take you and Advisor Song there!" Shi Yang, sweating, quickly offered his courtesy.

As soon as I entered the office, Guo Qian came over with a lunch box. The three of them chatted in the office while sharing the progress and eating.

At one o'clock, Duan Sijiu was brought in by Shi Yang.

"Xiao Li!" Duan Sijiu was confused when he came in. He probably didn't know why Li Xiangnan called him here.

Li Xiangnan didn't bother to stir up trouble. He showed him the rope in the evidence bag and asked, "Old Duan, someone was just hanged with this rope. I remember you told me that this fisherman's knot is a variant, right?"

Duan Sijiu cried out, his face frozen when he heard someone was dead, but he quickly recovered and sank into a chair. He looked at the knot with a pale face and recognized it in just two seconds: "This is a deadly fisherman's knot!"

After saying this, seeing Li Xiangnan and Guo Qian's eyes tighten, he studied it again: "This kind of knot is usually used between veteran dock workers and fishermen on boats. It requires skill to tie, and once it's tightened, it's extremely difficult to break free! Not many people know how to tie this knot now!"

He finished his words, his voice full of pity and sympathy, "How could someone kill someone with something like this?"

Li Xiangnan took the rope and said, "Old Duan, if I asked you to identify a fisherman who has been around for more than ten years, could you recognize him?"

"Yes!" Duan Sijiu nodded immediately. "People who live in the sea all year round have a special smell on their bodies! It's the smell of being pickled in the sea!"

Li Xiangnan and the other two were delighted and pushed the lunch box over. "Old Duan, after you finish your meal, go with Captain Guo to identify the murderer!"

"..." Duan Sijiu twitched his lips, looked at the fiery light in his eyes, and nodded subconsciously, "It's better to obey than to be respectful!"

Tatata!

At this time, Liu Yiming hurried into the office.

"Advisor Li, Forensic Doctor Wang called and asked you to return to the bureau immediately. There's a major discovery!"

"Oh?"

Upon hearing this, Li Xiangnan quickly stood up, tucked his coat in, and waved, "Captain Guo, Lao Duan, you guys stay here to investigate. Xiao Song and I will go back to the bureau!"

Guo Qian clasped his palms together and said excitedly, "Damn, this case was solved so quickly! Consultant Li, please come back quickly. I'll be waiting for your news!"

"I'm waiting for your news too! It's better to wait until I come back, because the murderer has been caught by you!"

Li Xiangnan smiled faintly and quickly led Song Zimo out...
