About ten minutes later, there was a sound of footwork outside the room and the sound of two people talking.

"Detective Zang, this is it!"

"Well!"

When they entered the room, Li Yifan followed the sound and saw Han Shaocheng, 60 or 70 years old, with white hair and casual clothes. Next to him was a middle-aged man in a suit, a hat, a capable temperament and a big detective look.

"Lao Shen, you are here!" When Han Shaocheng saw the room full of people, he said with a smile, "I'd like to introduce you to Zang long, a detective who used to be a criminal investigation policeman and has rich experience. Detective Zang, this is my old friend Lao Shen, who is also a traditional Chinese medicine doctor like me. "

The man who called Zang long nodded, "Hello everyone."

People can't help but look at Zang long curiously. Suddenly, Shen Tianfeng exclaimed in surprise, "I remember, you are the famous criminal investigation expert ten years ago, who is nicknamed know it all?"

Hearing this, Zang long turned his head in surprise. "I didn't expect that there were still people who remembered my name so long ago."

"It's you Shen Tianfeng opened his mouth wide and was very surprised. He immediately showed his joy, "great! If it is you, then the cause of Han Song's death can be investigated clearly! "

Shen Shaokun was surprised. "Is this man so powerful?"

He had the impression that none of the policemen who came to investigate the scene had been so positively appraised by Shen Tianfeng.

"Of course!" Shen Tianfeng nodded heavily, "I tell you, this detective Zang used to be a famous figure! When he was still in the police station, he was the leader of the criminal investigation team. Take a case 20 years ago. At that time, the case had been defined as a pending case and could not be investigated! As a result, you can guess what happened. Ten years ago, detective Zang accidentally saw that case and found out a pending case that could not be solved after ten years! "

Hearing this, they all widened their eyes and showed a strong color of surprise.

The reason why a pending case is a pending case is that the evidence is insufficient, or there are too many interference factors when the evidence is sufficient, which makes the case unable to be solved.

There are such cases every year. Generally speaking, some cases may be solved with the development of the times and the improvement of technical level, but there are always some cases that can never be solved.

The case Zang long saw at that time belonged to a case that was defined as impossible to solve by others!

"So powerful?"

"I'm worthy of being a detective!"

The Shen family couldn't help praising.

Hearing the praise from the public, Zang Long's plain face couldn't help showing a touch of satisfaction. Although it has been so long, his past achievements still make him enjoy this pursuit.

Li Yifan couldn't help nodding, "this guy really has some ability."

He did not deny the strength of others against his will. After all, he must have the ability to solve the outstanding cases.

"It seems that this time with the help of detective Zang, the case will surely be solved!" Han Gang cried happily.

"Yes! Please this time! " Han Shaocheng's eyes to Zang long are full of expectations.

Zang long took a deep breath and nodded, "I'll try my best, but I can't guarantee that if I can detect it, I have to see the scene of the crime."

His modesty made people nod.

"Let's go!" Li Yifan looks at Shen Shaokun.

Shen Shaokun nodded and was ready to follow. But before he took a few steps, he felt a little chilly on his back. Turning around, he saw Han Shaocheng looking at himself intentionally or unintentionally with a kind of extremely cold eyes.

He thought that Han Shaocheng would not hate him?

It's over, it's over!

It must be. Everyone thinks that he killed Han song, and Han song is Han Shaocheng's precious apprentice. It's strange that Han Shaocheng doesn't hate him.

Shen Shaokun's heart moaned and sighed and followed the crowd, shrinking his body and narrowing his sense of existence.

The scene of the crime was in a bedroom on the east side of the courtyard, which was used to rest the guests.

"Detective Zang, this room is the place where the Shen family receives guests most of the time. Although there are people living in it, it's not much. On the day of the crime, Han Song happened to follow Han Tianyi to my home as a guest. Because he was a young man, he didn't pay much attention to where Han Song went and let them stay together. "

"That afternoon, Han song and Shaokun were in this room. They quarreled because of a little bit of small things. Then we heard the voice and looked at the situation. It happened that Shaokun pushed Han song and caused him to fall. Then Han Song fell and never got up again. After the examination, it was found that the person was out of breath. "

Shen Tianfeng sighed as he explained the situation of the day.

Zang long thought about it and asked, "how many people saw him push people that day?"

"Two! I have one, and my wife has one. " Shen Tianfeng replied: "when he saw it, he found that someone had an accident. Shaokun immediately yelled and told everyone about it. Then we called the police. But when the police came, they couldn't find out the cause of death. ""I see. Open the door!" Zang long nodded.

"All right!"

Shen Tianfeng unscrewed the door lock. As soon as the door was opened, there was a smell of putrid corpses. Although it was not very strong, the smell of putrid corpses still made people nauseous.

Seeing people covering their noses and changing their faces, Shen Tianfeng explained helplessly: "although it's autumn now, the temperature is still very high, so the speed of corpse decay is very fast. Because the police told them to protect the scene of the crime, there was no way. The body was still inside. I just turned on the air conditioner and lowered the temperature in the room, but I still couldn't avoid the slow decay of the body. Let's all be patient a little bit! "

Under normal circumstances, when there was a homicide, the body had to be taken away for forensic examination.

But this time, the situation was special. The incident did not take long. After obtaining evidence at the scene, the police had no harvest and clue. After discussion, they decided not to transport the body away. They planned to discuss a suitable scheme and then test the body.

In order to protect the scene and avoid damaging the evidence, the body has not been moved, and the air conditioner is directly turned on to the lowest temperature, in order to avoid the rapid decay of the body, which will affect the final diagnosis of the case.

After they had protected themselves, they opened the door and went in.

"Stand by the door as much as you can, and don't touch anything in the room. Everything can be evidence," Zang longyi reminded everyone as soon as he entered the door, and everyone stood by the door with great cooperation.

Li Yifan's eyes swept back and forth in the room.

The first thing he saw was Han Song's body, which was lying on the ground in a very strange posture. From his distance and perspective, there were no scars or bruises on the surface of the body, which looked very normal.
