"Director, I know your concerns, but at least it's not too late for me to finish these two cases." Xu Sa persuaded Sun Ju bitterly.

Sun Ju looked at Xu Sa thoughtfully, his heart was reserved.

"You've been working under me for so many years, and I've treated you like half of my son, so okay, you can stay until this case is closed." Sun Ju also knows that it is not good to do too ugly, after all, there are still some feelings after getting along with each other for so many years.

"But you can't attend, you can only stay in the bureau." Sun Ju emphasized Xu Sa again.

"I understand." Xu Sa bowed to Sun Ju and left the office.

I met a lot of colleagues in the corridor, and everyone deliberately kept a distance from Xu Sa. Xu Sa understood why they were like this, and acquiesced in this embarrassing situation.

During the regular meeting in the morning, Su Tong took a photo of the physical evidence he obtained in the evening and asked He Xingchen to put it on the big screen. And the general progress was explained.

"Sun Ju," Xu Sa looked at Sun Ju, "I think the content of this letter is probably not that simple, I think we can pretend to release Shang Minghua and lure the murderer out." ”

But Wen Yan sat on the side and didn't think so. "I object, at the beginning we all suspected that Shang Minghua was hypnotized to commit the crime, in fact, he was very likely to be controlled by others, and now that Shang Minghua is released rashly, how can you be sure that he is not letting the tiger return to the mountain?"

"Officer Su, what do you think?" Sun Ju saw Xu Sa and Wen Yan fighting each other, so he had to look at Su Tong, "I also think it's not good to let Shang Minghua come out." Then he recounted what he had said last night.

"Officer Su has a point, then do what you think." Sun Ju finally agreed with Su Tong's idea.

Su Tong left the conference room with the people in his group and chose to sit around Su Tong's position to make a summary.

"This is what I read on that destroyed disc." He Xingchen turned up the volume on his laptop.

I can only hear what spring, what gang, and then there is a long piece of babbling strange music.

"What are these things?" He Xingchen scratched his head.

"Pure is pure, masculine is strong. Because it does not generate itself, it can live forever. Su Tong only vaguely heard these two sentences.

"What? Ancient Chinese? He Xingchen said dumbfounded.

"It's the Tao Te Ching! You idiot. Zhou Li looked at He Xingchen, is this person Chinese? I haven't even heard of the Tao Te Ching.

"Tao Te Ching?" He Xingchen looked at Su Tong.

"Not all, the first sentence is not, the latter sentence is the Tao Te Ching." Su Tong took a pen and wrote down those two sentences, repeating these two sentences in his mouth.

"What does that mean?" He Xingchen asked.

"Pure is pure, masculine is strong. Is it purely Zhong Yuehong? She was bred by her immediate family, and from the perspective of ancient times, the bloodline is the purest source. Yang refers to men, and heart yang refers to the heart..."

Su Tong began to ask himself again, "Could it be, could this be a sacrifice?" ”

Everyone was speechless, He Xingchen swallowed his saliva and sacrificed with the boy's heart?

"So in this CD, it might be some kind of cult slogan?" He Xingchen said unnaturally.

"Because it does not generate itself, it can live forever. The original meaning of this phrase refers to spiritual eternity. But I guess that's how the murderer misinterpreted the meaning of this sentence, thinking that by sacrificing people's hearts, they could get immortality. Su Tong shook his head and said with a complicated expression.

"But that's not right, if he wants to control people's hearts to achieve some kind of goal, then why did he kill Zhong Zhixin too?" Zhou Li looked at her notes, but still couldn't understand the murderer's intentions.

"Is the report of the evidence recovered last night out?" Su Tong looked at He Xingchen.

"There are still some that need to be identified, but the forensic team called and said that a suitcase was found under Zhong Zhixin's bed yesterday, which contained all kinds of anatomical textbooks, which were full of notes, and after handwriting identification, it was confirmed that Zhong Zhixin owned it." He Xingchen showed Su Tong the electronic version of the computer's appraisal report.

"And one of the CDs in this DVD box that Zhou Li retrieved, the contents of which were determined by Chen Lao to be the surgical process of cardiac dissection." He Xingchen switched the screen of the computer screen and clicked to play the video.

The person who was undergoing the operation did not expose the part above the chest during the whole process, nor did he speak, and the video content ranged from the preoperative preparation, the scalpel showed the detailed process including how to take the heart, and the person did not speak during the process.

"Can you find out when this video was filmed?" Su Tong asked.

"The source code of the video can only be found out about the model of the shooting and the time when the recording disc was uploaded, but not when it was filmed." He Xingchen shook his head, the shooting time of the video is not recorded, because as long as the standby button is pressed during the recording process, the date will remain fixed, and it can even be adjusted randomly.

"Ding-" The computer sent out a message alert. After He Xingchen checked it, he looked excited.

Shirley said that the man in the video who had surgery was probably between 30 and 40 years old, and his posture with a scalpel was unprofessional, and he was probably self-taught. He Xingchen handed the email that Shirley replied to Su Tong to see.

"1. There is a slight varicose phenomenon in the green muscles and blood vessels on the back of the hand, and this symptom will become more and more serious between the ages of 30 and 40. 2. Professional doctors will put the back of the knife against the finger of the index finger when using the scalpel, but the person in the video obviously often slides the knife, and the finger tip may have cocoons caused by other reasons, so the scalpel cannot be fixed.

3. The distal phalanges of those hands are significantly thicker than the middle and proximal phalanges, and this appearance is most common in pianists and anyone who needs to play an instrument with their fingers. 4. The lowest mistake is that the knife does not separate the three steps when cutting the muscle layer. ”

After Su Tong read Shirley's reply, he quickly locked on the suspect in his heart.

Immediately call Zhong Zhixin's mother and ask her to tell all the information about Zhong Zhixin's piano teacher. Send someone to arrest it as soon as you get the address. Su Tong picked up his mobile phone and dialed a certain number, and said to Zhou Li at the same time.

He Xingchen was so confused by this sudden contrast that he didn't know how to react, but he didn't soon understand.

"Hey, Old Chen, there's something I want to ask you for, so..."Su Tong said on the phone in a serious tone.

After she finished speaking, she turned around and found Xu Sa standing at the door of the conference room, looking at herself from afar. Su Tong avoided it weakly.

"Officer Su, Zhong Zhixin's mother said that the piano teacher lives in Anding Square in the center of the city, and it will take about twenty minutes for us to go there." Zhou Li hung up the phone and said quickly.
