Xiao Meng's weird smile was even more heartbreaking than when she was expressionless.

Cao Zhe handcuffed Xiao Meng, and Gu Qingtong ran to the villa to find out Cai Xiangli's whereabouts.

As soon as I entered the yard, a dull sound came from the direction of the pavilion.

"Sister Gu, there is a rope in the pavilion!"

Shi Dong followed Gu Qingtong's footsteps and the two ran over together.

Sure enough, Cai Xiangli's face turned into a pig's liver-colored face, and she lay crookedly on the ground. The knot hanging on the top of the pavilion was broken, and Cai Xiangli must have fallen heavily.

Gu Qingtong tried Cai Xiangli's breath, but fortunately, he was not dead.

She and Shi Dong worked together to place Cai Xiangli in a lateral position to prevent suffocation caused by food reflux in the stomach.

When Cai Xiangli breathed smoothly, Shi Dong helped Cai Xiangli sit up under Gu Qingtong's guidance.

"Teacher Cai, are you awake now?" Gu Qingtong took out Tian Xiaomei's photo and asked Cai Xiangli to identify it. "Look, do you know this person?"

Cai Xiangli burst into tears in an instant: "Xiao...Xiaomei...I was the one who hurt her!"

"Xiao Shitou, measure his pulse." Gu Qingtong closed the photo and said, "If the heartbeat within the normal range for a minute, we will take him back for interrogation."

Shi Dong did as he did. After taking the pulse, he said, "Sister Gu, it's normal. Teacher Cai is not in a serious condition."

Gu Qingtong greeted the police officers responsible for blocking the scene, and then left early with Shi Dong and Cai Xiangli.

-

Early in the morning of the interrogation, Zhao Hong from Forensics called Gu Qingtong: "Xiao Gu, the cotton swab you gave me last time that was dipped in tea did not detect any poison. We also tested all the brewing drinks at Cai Xiangli's home, but no poison/rat/strong residue was found."

"Thank you, Brother Zhao, I understand."

Gu Qingtong lowered the phone and immediately clicked on He Xing's roommate Wang Tao's academic profile.

Wang Tao's academic experience is no different from He Xing: excellent college entrance examination results and excellent undergraduate grades - the only difference is that He Xing has obtained a quota for master's and doctoral studies, but Wang Tao does not.

However, Wang Tao's master's thesis received national awards and naturally succeeded in the doctoral exam.

Will Wang Tao be jealous of the school’s generous treatment to He Xing? By chance, the two became roommates during their doctorate studies. Only they know the quality of the relationship, and outsiders have no way to know...

Soon, a prize that Wang Tao won in the last semester of his second year of high school came into Gu Qingtong's eyes.

The first prize in the Chemical Innovation Competition, and the winning project is the research and application of new types of rat-killing drugs.

A top student who studies modern language and literature has conducted in-depth research in the field of chemistry. What kind of versatile or geek is this?

In this way, He Xingji might have been poisoned in the dormitory - and he went to confront Cai Xiangli indignantly. It happened to be the toxic attack period, and happened to drink the coffee brewed by Xiao Meng again. It seemed that the poison was put into the coffee solution, but it was not the case.

Gu Qingtong contacted Wu Chen who stayed at the cleaning site of Jiangbei University: "Xiao Wu, you work with the university security department to control Wang Tao immediately. In addition, collect all the drinks and other water storage containers in Wang Tao's dormitory and send them to the forensic department as soon as possible!"

She immediately called back to Zhao Hong: "I have something to bother you, Brother Zhao, a colleague will send some samples to your place later. I suspect that the poison in the deceased He Xing was drunk into the stomach by drinking water."

Zhao Hongying said: "Okay, I'll tell you the results immediately after the test!"

-

Because this case involves a wide range of issues and has a bad social impact, Pan Shaofang decided to take action personally and serve as the presiding judge for the interrogation of Xiao Meng and Cai Xiangli.

At 9 a.m., the interrogation officially began.

Gu Qingtong stayed in the observation room next to the wall, paying close attention to the every move of the suspect on the monitor.

Pan Shaofang was straight to the point: "Meng Jia, Cai Xiangli tested the ingredients of sedative drugs in the milk he drank before going to bed. And you went to the hospital's sleep disorder clinic last week and prescribed the same medicine..."

Xiao Meng minds that others call her: "Excuse me, please call me Xiao Meng!"

Pan Shaofang did not change his words: "The surveillance video shows that Cai Xiangli fell asleep after taking milk containing sedative drugs. You tied him up with a rope and dragged him from the bedroom on the third floor to the yard. Meng Jia, the entire crime has been recorded. Do you have any other supplements?"

Xiao Meng sneered: "Cai Xiangli has the habit of taking sleeping pills, so I just increased the dose. But I didn't expect that an adult man would be heavier than a dead pig after fainting, which made me wasted a lot of time in the middle of the journey."

Admitting to drugging - Pan Shaofang wrote four words in the interrogation form and asked again: "Does there be any accomplices in the process of your premeditated murder of Cai Xiangli?"

"Yes!" Xiao Meng's hands suddenly fell onto the table, and the handcuffs collided with the table board, "Brother He Xing blessed me in the sky to make a smooth plan."

Pan Shaofang placed the photo of a man wearing a hooded sweatshirt and a black mask taken outside the villa to Xiao Meng.

"Meng Jia, please look carefully. Who is this man?"

"Wang Tao." Xiao Meng said without hesitation, "He sneaked into Cai Xiangli's home, but he failed. The walls were surrounded by anti-theft power grids, so he couldn't get in."

Pan Shaofang said: "We contacted Jiangbei University. Wang Tao's tutor and classmates from the same research group said that they hadn't seen him for three days. We also checked the dormitory, and Wang Tao should have not been back for a while."

Xiao Meng's face was calm: "Brother He Xing said that Wang Tao is a gunman to earn extra money, and he has never been home at night."

"Gunner?" Pan Shaofang paused, "Does the people who hired Wang Tao to write for him include Cai Xiangli?"

Xiao Meng shook his head: "I don't know."

Pan Shaofang raised his left hand and stayed above the photo, pointing to the date and time in the upper right corner of the surveillance video, and said: "Yesterday at 21:19, Wang Tao appeared outside Cai Xiangli Villa. And the time we arrested you was only half an hour later than Wang Tao appeared."

"Uncle police, do you have to make me admit that there is an accomplice?" Xiao Meng suddenly laughed, but she smiled very reluctantly. "I don't think there is any need to turn the car to confirm over and over again. I did everything myself. Cai Xiangli killed my brother He Xing. I want Cai Xiangli to pay for his life!"

Pan Shaofang closed the record book: "Meng Jia, if I told you that He Xing had planted the poison of the destruction/rat/pharmaceutical before going to Cai Xiangli to ask for an explanation, what would you think? Would you still think that Wang Tao is innocent?"

-

Half an hour later, Cai Xiangli sat on the chair in the interrogation room.

He twisted his body frequently and felt uncomfortable sitting on the chair: "Sir, can you change me to a soft sofa? I fell from such a high pavilion and my whole body was scattered. The iron chair was so uncomfortable!"

Based on humanitarian concerns, Pan Shaofang called the logistics department, and soon someone sent a thick soft chair cushion.

Cai Xiangli was still dissatisfied: "Isn't this perfunctory to me?"

Pan Shaofang was no longer disturbed by it: "Next, let's get back to the point, Cai Xiangli, I hope you don't find all kinds of excuses to evade interrogation."

Cai Xiangli said silently, silently took the chair cushion and sat upright.

Pan Shaofang said seriously: "Listen, we will bring you back. We are not asking you to assist in the investigation. You have officially listed the suspect in the murder case of Why Star. So, if you want to play word games, please give up this idea."

Cai Xiangli muttered: "I have never killed anyone, He Xing's death has nothing to do with me!"

Pan Shaofang asked incisively: "Is Tian Xiaomei's death related to you?"

As soon as the problem arose, Cai Xiangli was already dead: "Xiaomei...she..."

Pan Shaofang said: "Tian Xiaomei left the country to travel abroad on March 19, and the person who returned to China with her passport on April 10 suddenly became Meng Jia. Only you know the most about what happened, right?"

Cai Xiangli said word by word: "Meng Jia officially joined the company on March 3 and became my secretary. Xiaomei went through the handover procedures with her. Global travel is Xiaomei's always dream. Because she had to take care of my life, she could hardly leave Jinyang. This time, I agreed to her resign. After all, I can't keep her by my side for the rest of my life."

Pan Shaofang asked again: "Your book "Spring Mud" was published on March 31. You deliberately asked Tian Xiaomei to avoid it. Is there any hidden truth behind it? Meng Jia told Tian Xiaomei that she once mentioned that she was going to marry her boyfriend and travel. Do you know who this boyfriend is?"

Cai Xiangli sat down with his head down, and after a long time hesitated, "She concealed the facts. She was three months pregnant at that time, and the child was mine."

Hearing this, Gu Qingtong in the observation room was stunned in an instant.

The corpse contained in Xiao Meng's trolley box was pieced together by forensic doctors and was only part of the corpse. At present, the head, the middle section of the main trunk and the right leg tissue are still missing.

Forensic Science collected samples of the body fragments and tested and compared them with the DNA of Tian Xiaomei's parents, and confirmed that the deceased was undoubtedly Tian Xiaomei.

So where are the other missing parts of the body hidden now?

Why did the murderer cruelly dismember a woman pregnant with Rocca?

Wu Chen's number flashed on the screen of the mobile phone.

Gu Qingtong connected and asked, "What's wrong, Xiao Wu?"

"Sister Gu, half an hour ago, an unknown item was found in the cold storage of the university cafeteria, and it was suspected that frozen meat had no production date." Wu Chen said breathlessly, "Meng Jia worked part-time in the cafeteria in April and was responsible for the management and allocation of ingredients. At this time, the time when Hotan Xiaomei was killed is right! The forensic has sent someone here."

Gu Qingtong said: "Cai Xiangli mentioned that Tian Xiaomei is pregnant just now. Please check whether there is an unformed fetus during the autopsy. Xiao Wu, once it is confirmed that the frozen meat is the other part of Tian Xiaomei's body, you will immediately rush back with the report!"

Wu Chen replied "Received" and immediately hung up the machine and turned to work hard.

Gu Qingtong's gaze fell back to the monitor again.

Pan Shaofang's interrogation continued, and Cai Xiangli kept lowering his head, and answering questions seemed increasingly careless.

"It doesn't matter if you don't believe me. The surveillance camera captured all my activities." Cai Xiangli said, "On the day He Xing was killed, I was at home, bedroom, study, and restaurant all day. Of course, I went to the yard to bask in the sun in the afternoon. I didn't have time to commit the crime, Mr. Police Officer."

Cai Xiangli's home only has a door to the outside world, which was confirmed during the investigation.

However, during the interrogation of Xiao Meng, the Crime Team captured a surprising message-

Xiao Meng repeatedly emphasized that Cai Xiangli used to have a small iron door in his backyard, but later for the sake of anti-theft, the door was blocked. But somehow, at the end of April, the back door was restored to use. However, few people usually enter and exit here, and the wisteria flowers planted along the courtyard wall hung several bouquets, blocking the door tightly. If you don’t get close, you can’t find the existence of the door.

-

The interrogation has come to an end.

Before the sky was dark, Gu Qingtong and Shi Dong returned to Cai Xiangli's home and carried out a secondary investigation on the scene.

The heavy rainstorms for two consecutive days knocked all the floating catkins to the ground and ponds. The cicadas were still there, but the air was not as humid and stuffy as the previous few days.

The back door that Xiao Meng mentioned is indeed hidden on the back of the dense wisteria spikes.

Shi Dong tried to push the door, but the door didn't move at all.

Gu Qingtong turned on the flashlight and checked it up and down, but did not see an open or hidden lock, which means that the door was locked from outside.

They walked out of the main door and walked around the wall to where the back door was.

The light from the flashlight shone on an old rusty lock, and there was a clear palm print on the door panel around the lock, like a liquid stained with engine oil, and the fingerprints were quite clear.

Gu Qingtong said: "Little stone, collect fingerprints."

"clear."

As soon as Shi Dong opened the survey tool box, a black shadow suddenly jumped out from behind a big tree not far away.

The man staggered towards Gu Qingtong and Shi Dong, shouting while running.

"Save me...Save me..."

"Sister Gu, you may be in danger when you step back!"
