"Liang Li saw the man who gave Sang money, and I guess that man must not want Liang Li to see it. The man felt that Liang Li would reveal his secret, so he chose to kill her. But what exactly is the secret of the murderer? The biggest secret I can think of is that I bought Tong Sang to tell the truth about Zheng Wu's killing of Han Shuang. For this, even if we are known by the police, it will not have a big impact. Wang Shen shrugged his shoulders at Song Mu, showing a helpless look.

"By the way, on the day of Sang's accident, according to the driver who caused the accident, he didn't see the road clearly because he saw a burst of bright light, and he hit Sang. But where did that glare come from? If you shine on the convex lens downstairs from this position, will it reflect a dazzling light? Wang Shen seemed to think that he was a person in the fog, and he was anxious to seek Song Mu's help.

Song Mu sat on the chair, and most of the gleam in his eyes disappeared. He glanced at Wang Shen from time to time, and lowered his head from time to time, as if he was thinking about something. Wang Shen didn't back down at all, he left the window and walked towards Song Mu's desk step by step. Wang Shen walked to the opposite side of Song Mu, propped up the desk with both hands, and stared at Song Mu with his eyes. Song Mu didn't look at Wang Shen, just lowered his head solemnly, as if thinking about something.

"By the way, I suddenly remembered that I still have some things in my bureau to deal with in a hurry. For the rest of the time, I hope that Dr. Song will consider what I have said, and when I come to visit you again tomorrow, I hope you can give me a satisfactory answer. After speaking, Wang Shen gently knocked on the desk in front of Song Mu and left Song Mu's office.

"Hey, well, you send someone to keep an eye on someone for me. Well, yes, you go and say hello, but if you find him ordering a long-distance ticket or a plane ticket, he will be intercepted. Also, today monitor Song Mu's mobile phone and office phone, and record all calls, including the personal information of the caller. Yes, good work. As soon as Wang Shen walked out of the office building where Song Mu was, he called his colleagues in the bureau and asked them to closely monitor Song Mu's actions tonight to prevent Song Mu from planning to escape. If Wang Shen relied on the evidence he currently had, he could indeed apply for the arrest of Song Mu. But Wang Shen wanted to know more about Song Mu's motives for buying Tongsang and the reasons for killing Sang and Liang Li. Wang Shen always believes that when a person is in extreme panic, he will do something illogical. Naturally, it is also easier to expose flaws. So, this night, it's critical. Wang Shen hoped that Song Mu's actions would be as he wished.

Wang Shen returned to the police station and checked the results of Liang Li's autopsy, which showed that there were no obvious wounds on the rest of her body except for the fatal stab in the chest. Moreover, Liang Li showed no signs of being violated. The size of the shoe size has also been compared, and it is the same as Song Mu's size. Wang Shen looked at these analysis reports and guessed in his heart what Song Mu might do tonight. Suddenly, Wang Shen stretched out his arm, pinched the back of his neck, yawned, picked up his coat and left the police station.

Wang Shen didn't seem to have slept as well as he had this night for a long time, until a phone call woke him up from a good sleep. "What! Are you sure? Wait, I'll be right over! Wang Shen put down the phone, got dressed as fast as he could, stepped on the accelerator after a simple freshening up, and rushed all the way towards Song Mu's psychological clinic.

Someone reported that Song Mu committed suicide! This sentence was the first sentence Wang Shen heard when he picked up his phone. Song Mu's handling completely exceeded Wang Shen's expectations. Wang Shen originally thought that Song Mu would do some stupid things, such as talking to relevant people on the phone or something. However, according to colleagues in the police department, they tested Song Mu's phone all night and did not have any call records. Moreover, they also checked the surveillance downstairs of Song Mu's psychological clinic and did not find that Song Mu had left. Until early this morning, the police station received the news of Song Mu's suicide. The person who reported the case was Xu Wen, that is, Song Mu's only secretary.

Wang Shen pressed his temples while driving. To be honest, he really couldn't understand Song Mu's way of dealing with it. What could be more terrible in this world than death? Could it be that as Song Mu said yesterday, some people have too many sad things, and death is a relief for them?

It didn't take long for Wang Shen's car to stop at the door of Song Mu's office. Wang Shen didn't care about parking the car in the designated location, so he hurriedly got out of the car and rushed to Song Mu's psychological clinic. Wang Shen ran to the door of the psychological clinic, raised the cordon, and rushed into the scene.

"Team Wang, you're here, look at that." When a policeman saw Wang Shen arrive at the scene, he immediately put on a pair of rubber gloves and pointed at the computer screen on Song Mu's desk.

Wang Shen turned to the front of the computer screen and stared at the shimmering computer screen. A word file opens on the screen, unnamed. Wang Shen tried to read two lines: Today I am finally free, I have avenged Han Mo, and I will make him pay the price for anyone who bullied Han Mo...... This turned out to be Song Mu's confession!

Part of the confession reads as follows:

Today I am finally free, I avenged Han Mo, and whoever bullied Han Mo, I will make him pay. I also felt pathetic how stupid I was, why would I fall in love with a woman I had rejected. But love is like this, who can tell. I still remember the first time I met Han Mo, and the melancholy expression on her face was obviously a symptom of depression. But her somewhat antique beauty, combined with a little depression and melancholy, fascinated me. I'm sure I fell in love with her right then. I'm a person who doesn't believe in love at first sight, but for her, I believe. But fate doesn't always make people happy so easily. I'm a mentally clean person, and when I learned that she had been sexually assaulted by her stepfather more than once, I deliberately kept a safe distance from her. I can't accept such Han Mo. To be honest, my request for my other half is pure and quiet. And Han Mo didn't meet my expectations at all. But after all, I underestimated the power of love. That night, I learned of Han Mo's death, and I really realized that Han Mo's past experiences were nothing compared to my love for her. Perhaps, you will say, I don't love her that much. I don't know how to argue with it, but all I can do for her now is make those who bullied her pay.

Okay, I'm going to get to the point you want to know. My first target, of course, was Zheng Wu. This hateful scoundrel not only defiled Han Mo's body, but also made Han Mo's youth memory so miserable, and made me feel bad about Han Mo. I swear that I will avenge Han Mo and myself. I'm going to put this scoundrel in a situation from which he will never recover. After that, through Han Mo's narration, and under my many inquiries, I found the escort girl.
