Zeng Lei drove Yin Zhengyu and parked the car near Zuo Tongtong's clinic.

Zeng Lei looked into the clinic from a distance, and several busy figures appeared inside. Zeng Lei took out a pen and wrote something in his notebook. Yin Zhengyu on the side showed a curious expression, "Brother Lei, what are you writing?" ”

Zeng Lei said lightly: "Just remember the time." Then he asked, "Jungwoo, do you remember the route in the clinic?" ”

"Of course I do." Yin Zhengyu said proudly: "I can't forget it!" ”

"Okay, draw it to me!" Zeng Lei said, handing the pen and notebook to Yin Zhengyu.

Yin Zhengyu took it and quickly drew it on the notebook. He explained to Zeng Lei while drawing: "This is the gate, there is a side door here, enter from here, the first room on the left hand side is the infirmary, the first room on the right hand side is the ward, and the innermost room is the operating room......

Suddenly, Zeng Lei's mobile phone vibrate, and Zeng Lei pressed the Bluetooth headset hanging on his ear to answer. A Chao's voice came from inside: "Brother Lei, Zuo Tongtong does have a small animal breeding base near the address where he received the goods in the suburbs. It mainly raises juvenile mice, and some other small animals, all of which are suitable for medical experiments. ”

"Okay, got it. Ah Chao, help me check Zuo Tongtong's specific location now. Zeng Lei gave an order to Ah Chao.

"Okay, wait a minute." After a moment, Ah Chao replied: "Zuo Tongtong is in the clinic now, less than 20 meters away from you." ”

"Okay, Roger. Help me monitor her from now on, and notify me as soon as she leaves the clinic. Zeng Lei said solemnly.

"Yes!" Ah Chao received the order and immediately began to concentrate on listening to Zuo Tongtong.

Zeng Lei frowned and hung up the phone.

Yin Zhengyu just wanted to speak, but found that Zeng Lei's expression changed slightly, so he guessed Zeng Lei's intentions.

It was already dark, Zeng Lei glanced down at his watch, it was just after ten o'clock. Zeng Lei looked sideways at Yin Zhengyu, and when he saw Yin Zhengyu's appearance of wanting to speak and stopping, his brows gradually relaxed. "Zhengwoo, I'm going to enter the clinic now, you stay here and help me take care of the wind!"

"No, Brother Lei, I'll go! I went to the clinic last time, and I am familiar with the road. Yin Zhengyu put aside the pen and notebook in his hand.

Zeng Lei shook his head, "No, I have to go this time." The route you just talked about is very detailed, I have memorized it, don't worry. ”

Yin Zhengyu felt that Zeng Lei in front of him was not only full of confidence, but had a strong belief that forced him to take risks. Seeing that Zeng Lei had made up his mind, Yin Zhengyu didn't say anything more, and the two discussed the next countermeasures and response work.

After arranging, Zeng Lei cautiously drove the door and got out of the car, trotted all the way, and easily jumped over the outer wall of the clinic.

According to the route explained by Yin Zhengyu, Zeng Lei leaned over from the side door, and when he walked around the ward, he suddenly heard the sound of small footsteps, and he hid in the bathroom with a smoke. When the footsteps grew farther and quieter, until they were completely gone, he crept out of the bathroom.

Zeng Lei heard the sound of "squeaking" in the corridor, he looked around and saw a flickering room at the end of the corridor. The voice seemed to come from the operating room. According to Yoon Jung-woo's introduction, this room should be an operating room.

Zeng Lei walked over cautiously, looked in through the window on the door, and saw a woman in a white coat with medical rubber gloves on her hands, brutally dissecting a guinea pig. The table was filled with scalpels, tweezers, hemostats, injection needles, etc. The operating table was covered in blood, and the mice screamed and died. At the same time, a strange smell came from the operating room, and the smell of blood was particularly pungent, and Zeng Lei felt uncomfortable.

The one wearing the white coat was none other than Zuo Tongtong. Zuo Tongtong was already covered in blood, and while she was busy dissecting the mice, she kept wiping the blood on the operating table with a wet tissue.

This scene made Zeng Lei's heart tremble, he had never seen this scene before. The carcasses of the mice were scattered all over the place......
