The mice and rabbits that appear on the computer screen are particularly cute, making "squeaking" sounds from the boxes.

"It's so cute!" Ye Zi couldn't help but say.

Zeng Lei stared at the computer screen with both eyes, thinking that there would be a follow-up, but he didn't expect Liu Xuanang and Li Manke to let Zuo Tongtong and the two delivery men go after checking the small animals in the carton.

"That's the end of it?" Li Jian said angrily: "What is the situation? Why let her go? ”

"Jungwoo, what's going on?" Zeng Lei stared at the computer screen and asked.

Yin Zhengyu scratched his head and said, "I don't know!" ”

"It is indeed a small animal for medical experiments, and it is legal. Since it is legal, there is no need to pursue it further. Ah Chao opened Baidu on the computer while checking the information, and explained to everyone: "The size of the mouse is small, easy to operate, its reproductive cycle is fast, the cost is low, the sensitivity to various stimuli is strong, and it is easy to mark." It is the most versatile and commonly used animal in medical experiments. The big-eared white rabbit is characterized by large ears, white complexion, transparent and clear blood vessels, but poor resistance, and is also one of the animals often used in the laboratory. ”

"Did she buy so many critters for experiments?" Zeng Lei asked curiously.

"Because the genes of mice are very close to human genes, many diseases that are difficult to cure for humans can be found in mice, and some medical research and clinical experiments are done with mice." Ah Chao looked at the computer and said.

"Pigs are born to be punished for humans, they are so pitiful! Their lives are also lives, and it's inhumane to use them for experiments, right? Ye Zi felt that it was very unfair.

"It is said that many stray cats, stray dogs and frogs are also used for medical experiments, although it seems cruel, but if you think about it another way, they can dedicate themselves to science and contribute to human beings! This sacrifice is also a great sacrifice. Li Jian said.

Ah Chao continued: "Yes, it has also been openly discussed on the Internet, although some people have spoken out for mice in recent years, but the current scientific research is still necessary for mice. ”

"You can't use so many for experiments, can you? She regularly buys these small animals every week, which is quite a lot! What the hell is she going to do? Reselling? Yin Zhengyu analyzed.

"Could it be that these animals are being used to kill people?" Li Jian boldly guessed.

"Hmm." Zeng Lei nodded, revealing a look of surprise. Thinking and saying, "Now we can't rule out any suspicion!" Ah Chao, help me check if there is a breeding base for these small animals near Zuo Tongtong's receiving location. ”

"Yes!" Ah Chao quickly used the network to find out.

Zeng Lei continued: "Li Jian, track down the delivery van, check whether their license plate number is real, and trace its address. ”

"Yes!" Li Jian was also busy on the computer.

"Brother Lei, what about me? What do I do? Yin Zhengyu asked anxiously.

"You rest!" Zeng Lei pretended to be serious and said.

Yin Zhengyu asked, "Why?" Is it because I made a mistake? When everyone heard his words, they all turned their heads to look at him and Zeng Lei. Yin Zhengyu explained: "I know, I shouldn't have sold Guanzi just now, I should have told you directly that there were small animals in the box." ”

Zeng Lei smiled, "Your memory is so good?" Do you remember this so clearly? I forgot. With that, he walked straight to the door.

Yin Zhengyu obediently followed behind Zeng Lei with his head down, like a primary school student who did something wrong and was waiting to be punished by the teacher, with a good attitude of admitting his mistakes.

Looking back and seeing Yin Zhengyu's aggrieved and pitiful look, Zeng Lei couldn't help but smile and patted him on the shoulder, "Don't worry, I have more important work to hand over to you." ”

"Okay!" Yin Zhengyu readily agreed, showing a bright smile.
