How could Wang Ergou's body hang on the chassis of the car and fail to let Zhang Shunfa, who caused the accident, notice? This is the crux of the possibility of the kind of scenario that Li Bing hypothesizes.

Xiao Song said thoughtfully: "If Zhang Shunfa deliberately held the collision Wang Ergou on the chassis of the car, then he was intentionally murdering." In the light of the investigative situation, this seems unlikely. Because Zhang Shunfa did not slow down or stop after his car hit Wang Ergou, and when the people in the small restaurant heard the news, they did not see people or cars. In just a few seconds, if you hit someone and still tie them to the chassis of a car, even if it was premeditated, it is absolutely impossible. ”

Li Bing also took the opportunity to analyze: "In this way, there is only one possibility, after Wang Ergou hit the car, he was caught under the car, and then something was hung up, so he was dragged for 20 kilometers without the perpetrator noticing." ”

Xiao Song said: "Yes, but on the chassis of the car, what can hang on Wang Ergou's body?" If it is stuck by some parts, it is impossible to support Wang Ergou's weight and 20 kilometers of wild dragging, why is this? Are we wrong? ”

Zhang Yuanshan looked at the sad faces of the two and comforted: "Don't worry, think again." Alas, it is indeed inconceivable that a man's weight should be dragged for twenty kilometers, unless he is tied with a rope. ”

Xiao Song said: "Yes, if it is tied by a rope, then it can be judged that Zhang Shunfa is intentionally murdered." However, the situation analyzed on the spot is impossible at all, because he didn't slow down or stop, this is not something that can be done by manpower, is it really a ghost? ”

Li Bing was silent, and suddenly walked to his off-road vehicle and kept looking at the front windshield.

Li Bing suddenly said excitedly: "I found it, I found the answer!" ”

Xiao Song and Zhang Yuanshan hurriedly rushed to Li Bing's side, and Li Bing said happily: "You see, I guess it was like this at the time: when Zhang Shunfa hit Wang Ergou due to drunk driving on a rainy night, Wang Ergou's body was violently impacted and the front windshield was shattered. Zhang Shunfa was shocked, but he didn't expect Wang Ergou's body to roll off the hood and fall under the car. ”

Coincidentally, the upper part of the sealing ring on the front windshield also fell off with the shattering of the glass, which happened to cover Wang Ergou's waist. Therefore, Wang Ergou's body was caught in the sealing leather loop and hung under the chassis of the car. Zhang Shunfa ran wildly all the way, and Wang Ergou's lower body and legs landed on the ground, so the road surface was incomplete. ”

Xiao Song thought about it sideways for a while, and felt that Li Bing's analysis was quite reasonable. He asked excitedly: "Li Bing, then can you tell me why Zhang Shunfa tried to set fire to the car in vain to destroy the incriminating evidence, but did not burn Wang Ergou's body, but threw the body nearly two meters in front of the car?" ”

Li Bing smiled and said, "If the above speculation is true, it is not difficult to explain the mystery of throwing the corpse." Zhang Shunfa panicked and drove wildly. When his car hit the big tree, the car stopped instantly, and the body of Wang Ergou, which was hanging on the chassis of the car, was thrown out under the action of inertia. ”

At that time, because of the heavy rain and dark night, there were no street lights on the country road, so Zhang Shunfa panicked and did not find the body of Wang Ergou who was thrown out. He took out the gasoline, poured it on the driver's seat, lit it and fled. ”

Xiao Song high-fived and sighed, and his mouth suddenly opened. The only thing he is worried about now is whether the sealing ring on the windshield of the car can withstand Wang Ergou's weight and tow it for 20 kilometers.

Xiao Song thought for a while, dialed the number of the Xi'an criminal police, and asked them to quickly bring a car glass seal and sandbags to the scene of the crime.

Half an hour later, a police car arrived at the scene. Xiao Song greeted him and briefly reported Li Bing's analysis to the Xi'an criminal police.

Amid the exclamations of the crowd, the two detectives neatly hung the sealing ring on the hood of the police car. Xiao Song waved his hand and said, "Wait, if we want to truly simulate the scene of that day, we must start the test from the small restaurant in the city!" ”

The criminal police in Xi'an also agreed, and several cars carried everyone to the door of the small restaurant in the city one after the other.

Xiao Song instructed the two criminal policemen to hang the sandbags equivalent to Wang Ergou's weight on the chassis of the car with a sealing ring, and then drove the car himself, simulating Zhang Shunfa's drunken driving in the city at that time at a speed of 100 yards per hour, and drove to the suburbs.

The sandbags were firmly hung by the sealing ring and did not fall off, and even in the suburbs where the road conditions were poor, they were still hanging on the chassis well.

When they reached the almost abandoned country road, the speed was forced to slow down, to 60 miles per hour.

When he came to the big tree, Xiao Song braked suddenly, simulating the scene when Zhang Shunfa drove into the big tree.

A miracle appeared, after the car braked suddenly, the elimination bag that simulated the corpse of Wang Ergou, under the action of inertia, actually got rid of the constraints of the sealing ring hanging in the middle, rushed out of the chassis at once, and fell one and a half meters in front of the front of the car.

Everything has been verified, and everyone is happy that the mystery of this bizarre car accident has finally been revealed.

After a while, Xiao Song and Li Bing's expressions darkened almost at the same time. After a short period of joy, the two realized that although the mystery of solving the mystery that Wang Ergou was not murdered by someone, but really died in a car accident, it also meant that the clues to track Li Xiangmei's bizarre murder were interrupted.

The two returned to Xi'an, and after negotiating with the Xi'an criminal police, they agreed to criminally detain Zhang Anguo, who was suspected of robbing tombs, selling cultural relics, and killing Li Xiangmei, and approved Xiao Song to take Zhang Anguo back to Qianxian County for interrogation.

In the Qianxian County Criminal Police Team, after several hours of continuous interrogation of Zhang Anguo, the focus of the case fell on Mo Liwen, who entrusted Zhang Anguo with the custody of the Qing Dynasty court incense burner and then mysteriously disappeared for seven years.

Under the powerful psychological offensive, Zhang Anguo completely collapsed, and he confessed that it was he who rebelled and killed Mo Liwen.

Zhang Anguo confessed that seven years ago, Mo Liwen faced an investigation by the Xi'an Police Cultural Relics Investigation Brigade because of the tomb robbery. In a hurry, he found Zhang Anguo, who had a good personal relationship, and asked him to keep the incense burner on his behalf.

Zhang Anguo is also a master of the Tao, and when he saw this incense burner, he didn't realize that his eyes were full of strange purposes. Mo Liwen naturally saw all this in his eyes, he kept a hand and asked Zhang Anguo to write him a voucher.

Zhang Anguo almost without hesitation wrote a voucher and handed it to Mo Liwen, which made Mo Liwen feel at ease. When Mo Liwen eagerly asked Zhang Anguo how to secretly hide this priceless incense burner, Zhang Anguo pretended to pat Mo Liwen's shoulder and said, "Brother Mo, don't worry. With so many years of experience in tomb robbing, I naturally left a hand. I have an absolutely secret place to keep this incense burner, even if I commit a crime in the future and steal the family property. As long as you can find this incense burner after you come out, you and my brother will still have no worries about wealth for the rest of their lives. ”

Mo Liwen was overjoyed, how did he know that the place where Zhang Anguo said to hide the treasure was the tomb where Zhang Anguo planned to send Mo Liwen to the point of no return in order to engulf this rare treasure.
