The rain gradually became lighter and there was only strong wind left.

Bai Yutang's car drove off the highway quickly and slowed down a little in front of the botanical garden.

Zhan Zhao leans against the car window and looks at the botanical garden gate in the distance... The botanical garden is not a place for tourists on weekdays, and the trees are too lush, so overall it is a quiet and even gloomy place.

Zhan Zhao suddenly asked, "Who do you still remember the case of the Botanical Garden ten years ago?"

Zhao Hu raised his face and thought, "I was in high school ten years ago."

Ma Han looked at the botanical garden that was not very calm in the wind and rain, "What case was ten years ago?"

"Ten years ago, it should be when I was in college." Zhan Zhao said to himself.

Zhao Hu and Ma Han subconsciously looked at each other, and they were stunned and remembered, almost forgot that Zhan Zhao was a grade-skipping monster. He was studying for graduate school when an ordinary person was in high school.

Bai Yutang has always been with Zhan Zhao, and was together when he was in school, and he was a little puzzled, "How did you come into contact with the murder case at that time? Why didn't I know?"

"No." Zhan Zhao shook his head, "Do you still remember that summer vacation that year, when I often borrowed Gongsun's study to make a paper?"

Bai Yutang nodded, "Gongsun started to be a forensic doctor for the police station at that time. He was very busy every day, so he simply gave you all the keys at home."

Zhan Zhao nodded.

Zhao Hu and Ma Han were both a little curious and asked Zhan Zhao, "What happened at that time? Is it related to the case ten years ago?"

Zhan Zhao thought for a while and said, "The exact time of that day should be August 7th, on a typhoon day, it rained heavily and the wind was strong."

Bai Yutang frowned, not sure if there was such a day.

"You were taken to the police station by Uncle Bai that day." Zhan Zhao said, "I was sent by my father to Gongsun's house to find information. When I got home, your father and you picked me up. When we got home, the wind was very strong. There was a billboard on the road that almost hit our car."

Bai Yutang showed a clear expression on his face, and he had obviously remembered it and asked, "What happened that day?"

Zhan Zhao nodded, "That day, as usual, I found the information in Gongsun's study and started writing papers. At about three o'clock, Gongsun came back.

Everyone was waiting to listen to Zhan Zhao's words.

"Gongsun didn't run in and chat with me as usual, and didn't make a little noise, so I was a little doubtful if it was a thief." Zhan Zhao continued, "When I walked outside, I saw Gongsun wearing a black raincoat, his hair was soaked, and he was holding the tool box he would use when he went out for a mortal examination. He sat on a chair in the living room, looking straight ahead, and he was dazed. He didn't even change his shoes, and the carpet was covered with water.

Everyone was a little surprised. This phenomenon was used on Gongsun, which means two words - abnormal!

Although Gongsun is a forensic doctor, he is also a bit obsessed with cleanliness to some extent. He is very neat and picky. The biggest taboo in life is to enter the door without changing shoes!

In Gongsun's opinion, home is a quiet and free place. You must change your slippers when you enter the house. It is a crime to wear shoes and go directly into the room.

Bai Yutang also felt something was wrong and asked, "Gongsun seemed to be stimulating."

Zhan Zhao nodded.

"Ten years ago!" Zhao Hu leaned over and said, "Gongsun was still young at that time. I guess the autopsy was scared?"

After hearing Zhao Hu's words, Ma Han suddenly laughed.

Zhan Zhao also laughed.

Zhao Hu was puzzled and asked Ma Han, "What's so funny?"

Ma Han said, "If he was afraid of the corpse, he would not be a forensic doctor. When Xinxin went to the Medical University, she would take photos of all kinds of bloody corpses to eat. This is a professional quality."

"I don't think the body would scare Gongsun." Bai Yutang turned around and the car drove onto the coastal road.

"The scenery here is nice!" Zhao Hu was attracted by the scenery outside the window. "It's a pity that it's cloudy and windy. It should be fun to come here to ride a bike or run when the weather is good!"

Everyone looked out the window. At this time, the sea in the distance was stormy and stormy, but as Zhao Hu said, when the weather here is sunny, it must be very beautiful.

"What's wrong with Gongsun?" Bai Yutang pulled the topic back to Gongsun and asked Zhan Zhao.

Zhan Zhao's super memory made him feel like he had experienced the experience of the time again...

Seeing Gongsun in a daze, Zhan Zhao was afraid that he would be scared when he suddenly walked out, so he gently knocked on the door frame of the study.

Two "tuk" sounds really made Gongsun wake up suddenly. He looked up and saw Zhan Zhao, and seemed very surprised.

Zhan Zhao leaned against the door frame, looked at Gongsun curiously, and asked, "What's wrong with you? You're like you're terrified."

Gongsun suddenly sighed softly and said in an unknown way, "Isn't it just a ghost?"

...

After hearing Zhan Zhao say it, everyone was stunned.

Hu Zi's door was a little higher, "Crashing a ghost?"

Ma Han also felt strange, "Do Gongsun actually believe in these?"

"He said this and stopped talking about it. He soon went to work hard again." Zhan Zhao said, "This matter was not mentioned afterwards. However, when I saw the unsolved criminal files of the police station, I discovered the case that happened that day.

Zhan Zhao leaned on the back of the chair and looked at the turbulent seaside beside the road around the sea. "The case that day was a woman hanged herself on a longan tree in the botanical garden."

"Suicide case?" Ma Han asked.

"Gongsun was responsible for the autopsy at that time." Zhan Zhao said, "his autopsy report clearly stated that it was homicide."

"I also looked at the scene photos on the information. The longan tree was quite tall. The branches hanging on the body were nearly ten meters away from the ground. The female deceased was wearing a pair of high heels on her feet. She was just hanging on the tree with a decent look." Zhan Zhao recalled the case in her memory. "At that time, the police transferred the cloud ladder from the fire brigade. Gongsun should have gone up the cloud ladder to check the scene. In addition to many details that were artificially hung up, he also found a very strange detail."

"What details?" Zhao Hu was curious.

"The knot of the rope that hangs the corpse." Zhan Zhao pulled out a napkin and rolled it into a rope shape, and then said, "Gongsun took photos of the knot of the rope from all angles. It was a knot method that I had never seen before."

Zhan Zhao tied the knot and showed it to Ma Han and Zhao Hu behind him.

Ma Han frowned slightly. He had never seen this knotting method before.

Zhao Hu picked up the knot and said, "This is a knot used for marking."

Zhao Hu said something, Zhan Zhao was surprised, "I have checked many books but I have not found the meaning of this knot..."

Hu Zi was so amused and crying, "Of course I can't find it in the book! This is for thieves and is used for counting."

"Count?" Bai Yutang was also confused.

Zhao Hu nodded, "Before the thief started, they touched the bottom, especially some places with guards. For example, three guards at the front door, two back doors, and one next to the window. As long as you tie this kind of knot in an inconspicuous place, I used to play with a group of undercover agents, and they taught me. However, those who can use this technique are all old people, and young people rarely use it. Modern thieves use invisible ink, wear special glasses, and even write an article on the door of others. "While speaking, Zhao Hu took a few more napkins and rubbed them into long strips, demonstrating the knots for everyone, "This is one, this is two, this is three..."

When Zhao Hu demonstrated the knot that Zhan Zhao had just tied, he said, "This number means six."

"Six..." Zhan Zhao frowned.

At this time, Bai Yutang stopped the car and looked out the window and arrived at the residential area on the beach. Although this place is not as luxurious as the villa area on the distant hillside, it is definitely a very high-end community. However, it is far away from the city, and young people may find it inconvenient, but it is definitely suitable for the elderly to spend their old age in peace. The key is that the environment is good.

"Is Liu Jin living alone?" Bai Yutang asked.

Zhan Zhao looked at the information, "His wife divorced him when he was diagnosed with half of the disease. He never remarried since then and lived alone."

At this time, the rain had stopped, and only strong wind was left. Everyone got out of the car and walked into the community. The wind was mostly gone by the buildings on both sides. The entire community was spotless, clean and beautiful.

"What's the housing prices here?" Zhao Hu went to the gossip.

"It was very cheap at the beginning, and it was not very expensive now. After all, it was too far from the city." Zhan Zhao said, "Liu Jin's financial situation is quite good. In addition to his rich income, he also has enough wealth. In addition, he has two sons, a doctor and a pilot, both of which are quite reliable. His wife, who divorced him, is a painter, and now they are still in touch..."

While reading the information, Zhan Zhao sighed, "Where did Jiang Ping find so many messy information? It's comparable to gossip magazines!"

After walking around the garden community for a few times, everyone finally arrived in front of Building 7 where Liu Jin lived.

Building 7 has three floors in total, all of which are duplex. Liu Jin lives on the third floor.

Zhan Zhao and others raised their faces and found that the balcony of this small building was very large. There were no windows on the balcony on the third floor. The scene above the balcony made everyone feel a little stupid.

I saw more than a dozen rows of small windmills hanging on the ceiling of the balcony on the third floor.

Zhan Zhao couldn't help but praise the designer who came up with this roof design plan. The taste was so unique!

The yellow and blue four-leaf windmills should be made of plastic paper, one by one, one by one, hanging horizontally on the roof, and hung several rows, hanging the entire roof full of... The wind was strong now, and all the windmills turned around, and the scene was strange from the downstairs.

"This is quite creative." Zhao Hu said.

Ma Han frowned, "Will you feel dizzy after watching it for a long time?"

Bai Yutang took a look and felt that watching more might cause "intensive phobia", so he walked over and rang the electronic doorbell.

Zhan Zhao also looked up at the rows of windmills that were rotating rapidly, thinking about something.

After the doorbell rang three times, a voice came, "Who is it?"

Everyone was slightly stunned, and the sound was like a little girl.

"Hello, we are from the police station, look for Liu Jin." Bai Yutang replied.

"Oh, grandpa!" The little girl called out to grandpa from the electronic doorbell, and the noise was quite loud.

Everyone looked at each other, maybe they were their granddaughters.

After a while, the door was opened with a "click".

Bai Yutang and others entered the building. When they turned around, they saw Zhan Zhao standing downstairs looking at the roof, so they waved to him.

Zhan Zhao ran in and everyone walked upstairs. Bai Yutang suddenly asked, "The case in the Botanical Garden has never been solved? Are there any other clues?"

Zhan Zhao shook his head, "The police have no clues at all."

"Why did Gongsun say hell?" Bai Yutang was curious.

"I really don't know this." Zhan Zhao shook his head, "Ask him after he goes back? When I mentioned this in the morning, although he was a little uncomfortable, he was not particularly repulsive."

Bai Yutang nodded, and while he was speaking, everyone had already reached the door of the third floor.
