The location of Su Yan's car accident was located in the middle of Huanshan Road, a wide road sandwiched by a green forest. When I looked at the photos before, I vaguely felt that something was strange. Now when I arrived at the scene, Fu Yi felt more and more that the scene of the car accident seemed to be too shallow compared to the cases they had handled before.

Although it has been more than ten days since the incident, the scene is next to the mountain road, and people and cars are coming and going, and the preservation is no longer complete, but in the late autumn season, the plants and trees will not be released again. The accident site is not covered by natural plant growth, so the traces left by the vehicle collision on the roadside and on the grass are still relatively regular.

"Fu Team."

Yang Kaitai ran over with two pairs of gloves, squatted down and handed him a pair, and put on one.

Fu Yi wiped off the dead branches and leaves that were stained on his fingers, put on gloves, continued to fiddle with the hard grass roots, and said, "Did you find it?"

The police in Dongcheng District have searched the scene. It is difficult for them to find any new remains when they return to the scene. However, Yang Kaitai still knelt on the grass with gloves, looking for clues very carefully. When Fu Yi asked him, he said, "I discovered that this road is very wide, and the probability of a car accident is actually not high." He said, looking up at him: "Is that man-made?"

"Don't think so much."

Fu Yi said: "Chu Xingyun thought it was an accident, so let's check it out first."

As he said that, he stood up, glanced around the grass where tire marks were stuck, and said, "No need to look for it anymore, nothing was left."

He walked to the middle of the empty road and looked at the scene of the car accident from a global perspective, trying to reproduce the process of the car accident in his mind based on the few remaining ruts.

The destruction of the plants and trees at the scene was not very serious, and even the ground was not lifted up a few pieces. It can be seen that the collision was not very tragic. The road was very wide, and the probability of two cars colliding in the opposite direction was very low. On the day of the incident, they investigated the toll station at the foot of the mountain. There were not many vehicles going up and down the mountain at the time of the incident, so the vehicles on the left and right lanes could maintain a safe distance, and the probability of collision in the left and right lanes was not high. Moreover, just now he discovered that there was a suspicion at the scene, leaving three identifiable tire marks on the scene, one belonged to Su Yan's disappearance, and the other two belonged to Su Yan's vehicles that were still unknown to the suspect. These three traces all produced a drooping angle of nearly 90 degrees from the roadside, which was very regular. This was rare in the messy and complicated car accident scenes in the past. At least so far, he had never seen such a "concise and clear" scene.

Since it is impossible to collide in the opposite direction and the left and right lanes are impossible, the only possibility remains is the 't' type collision. Su Yan's car represents a horizontal line, and the suspect's car represents a horizontal line. The premise for this assumption is that there is a 't'-shaped mountain road on site.

Coincidentally, behind him is a mountain road connected to the mountain road into a 't' shape.

Fu Yi turned around and looked up at the mountain road that was winding upwards and gradually higher at an altitude.

"...Sanyang, drive the car over."

Yang Kaitai drove the off-road parked not far away over to him. After Fu Yi got on the bus, he asked, "Where are you going?"

Fu Yi pointed to the narrow mountain road leading to the shaded clusters and said, "Go up."

This road leads to the hot spring club, and Fu Yi found that this road is a one-way road, connecting to the 103 Ringshan Road and inheriting the hot spring club. In other words, those who walk down the mountain may have a starting point of the hot spring club.

In the car, Fu Yi kept silent and looked at the jungle flashing outside the window with a little thought. Yang Kaitai drove the car and looked at him frequently, waiting for him to say something, but he didn't say anything, so he had to interrupt his thoughts and said, "Captain Fu, are we going to the hot spring club to investigate Lin Yu?"

Fu Yi came back to his senses and said, "Well, I've seen the scene carefully just now. There is little chance of a collision between vehicles on the same highway. The only trace left to track down is this road. Lin Yu is the 'party' mentioned by Wu Ya, and her suspicion cannot be washed away."

Yang Kaitai thought about it and suddenly said, "Oh, I understand."

Fu Yi glanced at him and asked with a smile: "What do you understand?"

Yang Kaitai said: "Maybe Lin Yu ran into Su Yan when he drove into Highway 103."

"It's barely established, but there is a point. Lin Yu has to drive to have a car accident with Su Yan."

As she said that, Fu Yi paused and said, "But she insisted that she was just out for a walk and didn't drive."

"When she drove, we will find out if we went to the hot spring club to check the entry and exit records and surveillance."

He was right. It is easy to verify whether Lin Yu drove out, but Fu Yi has been a little uneasy.

Linjinchu is a double-story luxury mansion-style ancient building, which has created a British, European and American architectural style. At first glance, it looks like a palace and a nobleman.

They parked their cars by a hundred-meter corridor, then walked up the neatly tidy cobblestone path, and walked towards the hot spring club where they swallowed water.

When he arrived at the front desk of the lobby on the first floor, Fu Yi showed his ID and asked the front desk to retrieve all the records of Lin Yu's booking on the day of the room. The front desk staff consulted the lobby manager before starting to adjust the information.

"Ms. Lin Yu booked the room on October 19th, and the reservation time was two days."

Fu Yi's eyes darkened: "Two days?"

"Yes, two days, from 2 noon on the 21st to 6 p.m. on the 22nd."

Fu Yi suddenly walked around the front desk, walked to the staff, looked at the computer screen and asked, "What room did she booked?"

The staff brought out the thumbnail of the room and said, "It's a double couple's suite."

"She swipes the card or pays cash?"

"Swipe the card."

"Card swipe records are retrieving."

In less than five minutes, the staff found Lin Yu's card swipe record, and Fu Yi looked carefully. The cardholder of the bank card was indeed Lin Yu.

Fu Yi was discouraged for a moment and asked again: "Does there be a camera in the garage?"

The staff quickly adjusted the surveillance videos from the exit of the corridor on the 21st and the garage, and gave them up two computers at the front desk.

In fact, there is no need to check the surveillance at the exit of the corridor, because he found the parking staff and drove Lin Yu's red Audi into the garage. The red Audi was parked by chance. It was facing the camera and a doll behind the windshield was clearly seen. The car had never left the surveillance until after ten o'clock on the 21st, Lin Yu came back from outside, checked out and drove away. The time she returned to the hotel happened to meet the time point Wu Ya mentioned. So Lin Yu did not drive out during the day, and there was no possibility of colliding with Su Yan.

Lin Yu didn't drive, who did the other car at the accident site belong to?

After Fu Yi watched the surveillance, a layer of anxiety appeared in his calm and soft eyes. All the clues they looked for were proven to be "perjury". Another person at the scene of the car accident has not even had a personal choice!

He suddenly raised his hand to hold his forehead, which scared Yang Kaitai.

That is, my relationship with him is not as good as before recently, so Yang Kaitai learned a lot about him and realized that Fu Yi had a headache when he was frustrated. He was always very gentle, so he didn't often have an attack. The last time Yang Kaitai saw him with a headache was because the family of Shu Qing didn't know the inside story of Shu Qing's divorce from him two days ago, and blocked him at the entrance of the kindergarten and scolded him for being unfaithful and asking for custody of the child.

Yang Kaitai hurried over and held his arm, hurriedly looked around in the first-floor lobby, and then grabbed his hand and walked to a corner where the tea area was not eye-catching.

"Are you okay?"

Yang Kaitai bought a hot drink at the bar, squatted in front of him, and handed him the cup.

Fu Yi sat on the sofa, took the cup and held it in his hand, supported his forehead and frowned, "It's okay, just wait a little."

Yang Kaitai looked at his uncomfortable look and said worriedly: "Or why, let's go check in."

Fu Yi opened his eyes and looked at him, and a smile slowly appeared on the corner of his lips: "During work, you can't check in a room."

Yang Kaitai was stunned for a moment, and suddenly remembered something, and his ears were all red with a "swish" sound. He hurriedly got up and left his gaze and walked behind him, skillfully pressing his temples with his thumb, and muttering with a red face: "I just want you to have a rest."

After teasing him, his mood had to be relieved. Fu Yi gradually suppressed the biliary depression that had accumulated in his heart under his professional massage technique. He took a sip of the hot black tea he bought and said, "Maybe we should start with the relationship between Lin Yu and Shi Haicheng."

"What can the relationship between the two of them?"

Fu Yi looked at the direction of the front desk and said thoughtfully: "Lin Yu has decided on a double couple suite, which lasts two days, just for the weekend. Shi Haicheng also went up the mountain to attend the wedding on No. 21. Because there was something wrong in the middle, he left before four o'clock. Lin Yu arrived at the hotel at four o'clock, does it seem like...... they made an appointment?"

Yang Kaitai also heard something unusual, and thought about it, and then withdrew some force in his hand. After thinking for a while, he said, "Even if there is a male-female relationship between her and Shi Haicheng, what help will it be with the case? Overturn the witness she made for Shi Haicheng? The suspect still couldn't find it, and the other tire mark at the scene was still inconsistent with Shi Haicheng's car."

Yes, we cannot be distorted by the fact that even if Lin Yu and Shi Haicheng have a male-female relationship, they can only suspect that Lin Yu gave Shi Haicheng the witness. It still cannot be proved that Shi Haicheng is another protagonist in the car accident.

The thoughts were in a deadlock again, and Fu Yi felt bored again, lowered his eyes and thought hard, trying to find another way out of the muddy dilemma in front of him.

Although Yang Kaitai was not as good as him, he was not lazy. While helping him with massage, he analyzed the case in his heart.

Both of them thought about each other and didn't say anything. Just as his wrists were gradually becoming sore, he suddenly heard Fu Yi say, "We've missed a key issue."

Yang Kaitai hurriedly asked: "What's the question?"

Fu Yi's dark and quiet eyes seemed to have lit two jumping candles, his eyes were empty and focused, as if he had penetrated the space he was in and saw another space that was intertwined, which contained many chaotic scenes that had passed away.

"We are all looking for clues about whether another trace of the car accident scene belongs to Lin Yu or Shi Haicheng. But we only ignore the proportion of people and cars at the car accident scene."

His words were complicated and profound. Yang Kaitai had to stop his work, put his hands on his shoulders, stretched his head over his shoulder to look at him: "What proportion?"

Fu Yi patted the empty seat beside him and signaled him to sit over. After Yang Kaitai sat next to him, he said: "Su Yan and the suspect collided at the intersection. How many people and how many cars are there?"

Yang Kaitai: "...two people, two cars."

This question is so simple, are you testing him?

Fu Yi gave him a little restless smile and continued: "Su Yan died at the scene of the car accident. If the suspect wants to destroy Su Yan's body, the best way is what Wu Ya said, find a lake to sink. Then when the suspect was driving Su Yan's car to sink to the lake, how many cars were there at the scene?"

This question sounds simple, Yang Kaitai said without hesitation: "A car, the suspect drove Su Yan's car away, so the suspect's car should still be there-" As he said that, he suddenly fell silent, and then his eyes lit up: "Captain Fu, I remember we visited several passers-by who went down the mountain at around 4 o'clock. They all passed by the accident scene, but they all said they did not see the vehicle!"

Fu Yi nodded: "Yes, someone drove the suspect's car away. In other words, the participants in the car accident were not two people, but three people. In addition to Su Yan, there were two suspects. And the two suspects were in the same car, so that no car was left behind at the scene."

Yang Kaitai stopped and thought for a while, suddenly grabbed his hand and said excitedly: "Lin Yu! She didn't drive down the mountain, she was Shi Haicheng's helper! She didn't drive down the mountain, maybe Shi Haicheng came to pick her up, which just fits our speculation!"

As he said that, he suspected: "But Shi Haicheng's car had already changed its tires, and the traces left by the accident scene were not his car."

Fu Yi took another sip of hot black tea, then stood up and tidyed the collar of the coat, and said, "His car has indeed changed its tires, but it was replaced on the 21st or before the 21st. At present, it cannot be verified by an invoice and outbound record of Yu's repair shop." He said, "Don't you doubt where Lin Yu went between 4:30 and 9:30?"

Yang Kaitai suddenly understood, stood up and said in a hurry: "Change tires! She drove away Shi Haicheng's car, and she spent those hours changing the tires! Then Shi Haicheng's car was not replaced a week ago, but on the 21st day!"

The child has made great progress. Fu Yi looked at him with great satisfaction, then raised his hand and stroked his neck, saying, "That's right, so we should find out if there are any repair shops around us. The scale does not need to be very large, because large factories have monitoring and records, and a small factory opened privately is just right."

The next goal was obvious, looking for the repair shop around the hot spring club. Fu Yi asked for help from the front desk and asked her where there was a repair shop around. The front desk staff brought out a detailed electronic map for them to show. Fu Yi recorded the general locations of these factories, then took photos with his mobile phone, and left the hot spring club.

While looking for a hypothetical car repair shop, Yang Kaitai couldn't help but sigh that Fu Yi's sense of direction was really good. All the mountain roads looked the same, but he remembered who was who and could still shuttle through it unimpededly.

Two hours later, they finally found a small factory located at the corner of the repaired car park, converted into an abandoned gas station. Several electric cars and motorcycles were parked in the factory, and a thin old man was sitting at the door and was scrubbing a set of wrench covered with engine oil.

Fu Yi got out of the car and asked him, but the old man was older, and he was not only strong, but also deaf and couldn't speak clearly. What he asked, but the old man just waved his hand and signaled that he couldn't understand.

Fu Yi found Lin Yu's photo for him to show him. The old man only recognized him for a moment and turned his head impatiently, saying some vague dialects in his mouth.

Without the help of the old man, Fu Yi had to walk around the factory by himself and soon found a stack of replaced tires in the corner. He didn't know if there were any one in Shi Haicheng's car. He took photos of each tire, then greeted the old man, and returned to the car.

"Mr. Fu, what should I do now?"

Seeing that the speculation could be verified, but the old man who repaired the car could not cooperate, Yang Kaitai felt a little anxious.

Fu Yi took out his cell phone without any haste and dialed it out, saying, "Let's see Chu Xingyun now."

Chu Xingyun had just got out of the taxi when he received his call. He heard him tell the whole story of the cause and effect, lowered his head slightly, his face was gloomy, and said, "I understand, you will bring Shi Haicheng and Lin Yu back now."

"Have you found evidence that you can overthrow Shi Haimao's confession?"

Fu Yi asked.
