For medical experiments, the most commonly used are xiǎo animals such as xiǎo white rats and rabbits.

Artificially raised rats have poor adaptation to the environment, are not tolerant to cold and heat, and the living environment requires cleanliness and dust-free, and the temperature, humidity, fresh and pure air must be guaranteed, and the noise should be regularly ventilated, which is very pampered.

So Wang Zhuo trained two assistants, Meng Shengnan and Meng Shengdi, who specialized in helping him raise xiǎo white mice.

Although the conditions are good and the money is not bad, the feeding of xiǎo white mice is automated, and they can survive well if they don't see a living person for three days, but many links are still inseparable from manual processing, the Meng sisters live in the countryside from xiǎo, which of the ducks, geese, dogs and pigs have not been fed, and it is really not difficult to take care of a few boxes of xiǎo white mice.

Wang Zhuo's rat house is located next door to his laboratory, about 20 square meters, which houses more than 200 xiǎo white rats, and the reproduction rate of this kind of thing is quite amazing, so one xiǎo rat house is enough for him to use for all his experiments.

Engaging in the industry of "xiǎo white rats" is indeed high-risk and unrewarded, no, the number of rats has dropped significantly in recent days, although Wang Zhuo has the help of perspective eyes, he can observe the state of the white rats in detail, and many times save the trouble of chōu blood testing, there are still countless xiǎo white rats in his experiments honorably righteous, becoming batch after batch of martyrs.

So, after Wang Zhuo summoned the NV people to come to Wen Cun but failed, a phone call called the two sisters over, and today's task is to breed the Xiǎo Bai!

The young nv who grew up in the countryside is precocious, he has seen jī stepping on his back at the age of three and seeing the crotch of a dog at the age of five, Meng Shengnan has even seen the grand occasion of pig breeding, and he does not feel ashamed of the jiāo match of xiǎo white rats, on the contrary, he is also careful and meticulous, which is a good apprentice that professors in medical schools can't find with lanterns.

Wang Zhuo's rat house adopts the cycle breeding method, that is, after a male rat and a female mouse live together for ten days, then change to another rat tank, and live with the next female mouse for another ten days, and the cycle goes on like this, until the male rat is old and weak, and can no longer be qualified for this glorious mission, and then it will be eliminated. Meng Shengdi, who was doing a physical examination of a xiǎo male rat, suddenly had a pointed question.

"I don't know what you mean." Sister Meng Shengnan shook her head casually, put a healthy female mouse into a clean rat tank, and put it back on the rat rack.

"Look" Meng Shengdi glanced out, and saw that Wang Zhuo in the laboratory was immersed in stirring a test tube, and she didn't pay attention to the situation here, she whispered: "The male to female ratio of breeding rats is one to five, and one male has five females as wives, sometimes the demand for young mice is large, and the Jiāo mating cycle will drop for a few days, so it will become one to seven, one to nine." This is not fair, those male rats that did not become breeding rats were directly pricked to death by Wang Zhuo! As soon as she explained this, Meng Shengnan finally understood what she meant by imbalance She smiled faintly and said: "What's fair and unfair, isn't our Taoyuan also more men and fewer men, if Abba wasn't the village chief, he would have three or four wives." ”

"But in a big city, a man can only have one wife." , Meng Shengdi has obviously integrated into the germ of modern life, and has some resistance to one man's possession of more than one person.

And Meng Shengnan's thinking is not as "avant-garde" as her sister, she snorted disdainfully and said: "Only those men who have no ability have only one wife." ”

"Uh......", my sister, who was already nearly five centimeters taller than my sister, was suddenly choked dumb. Speechless.

"Take these xiǎo white rats, for example.

Meng Shengnan, whose figure was already developing in the direction of maturity, raised his eyes and looked at his sister, and explained: "It is their ability to grow a healthy and strong body, those who do not meet the standards will be directly immersed in the bottle and drowned, and those who meet the standards can live for a while longer, and finally die in the experimental box, only the strongest part of the individual has the right to mate with different xìngjiāo and reproduce." This is called natural selection, and the weak can only be eliminated, and there is no difference between humans and rats in this regard. Meng Shengdi's disdainful flat mouth, but she couldn't organize to refute her sister's words, although she was not convinced, and she didn't have the ability to quarrel with her sister.

Meng Shengnan saw that her sister had nothing to say but was still not convinced, and felt that it was necessary to point out again," she pointed to several young mice in the cardboard box on the side and said: "Actually, female mice are not the same, don't look at the selection rate is five or six times higher than that of male mice, but those with bad conditions are still eliminated." These eliminated ones also want to be selected and live comfortably for a few more days, but they don't even have that qualification. After speaking, she walked to the side to brush the mouse can, Meng Shengdi was stunned for a moment, and suddenly realized, my sister is reminding herself that if you don't work well, you won't be able to live a good life in the future!

Shao NV was immediately unconvinced, and said in his heart that we are also a school huā, although he is often teased by his classmates because of ignorance, but it will not be mixed up and no one wants it, right? What do you call this, referring to the scolding groove?"

She was so angry that she was about to find her sister to theorize, and at this moment, Wang Zhuo walked by! I knocked on the glass window between the lab and the rat house and pressed the intercom.

"Shengdi, send me a set of rats." , Meng Shengdi hurriedly agreed: "Oh! Coming soon! ”

She quickly prepared nine xiǎo white rats that met the standards, put them in a cage, and sent them to Wang Zhuo.

After Wang Zhuo accepted the xiǎo white rats, he began to inject shèyào agents one by one and make records, and she gathered on the side to watch attentively, assisting Wang Zhuo to send the xiǎo white rats into the glass box.

After Wang Zhuo finished everything, she smiled and pointed to a xiǎo white mouse in a glass jar: "Brother Wang Zhuo, why did this mouse máo fall off, it's so ugly." Wang Zhuo turned his head to look at it and said with a smile: "That group of experiments failed, but this one doesn't know what's going on, it lives the longest, and I'm waiting for it to die so that I can make a record." ”

"Oh......" Meng Shengdi laughed and joked: "Then you have to record it well, maybe because of this mouse, you can invent the máo liquid." I've heard that the invention of Viagra is crooked. ”

Wang Zhuo was dizzy and almost knocked over the test tube box, Wu looked at her with a smile: "Where did you know about viagra?" ”

"Go up again" Meng Shengdi chuckled, not blushing at all: "Am I not right?" Did Viagra originally want to be used to treat cardiovascular disease, but unexpectedly it was used to treat another disease? Wang Zhuo glanced at her in surprise, and secretly guessed if she didn't understand what the symptoms of the disease treated with viagra were, but Shao nv s cunning expression quickly made him negate this judgment She understood it in her heart!

Wang Zhuo immediately scratched his head, looking at the young NV standing in front of her, she was still in the green chūn stage, her body had just completed the transition from NV child to young NV, her height had reached the height of 1.62 meters, 63, and her weight was about 80 catties, like a crisp bean sprout.

It can be opened, but it has no nutrients.

Comparing it with Meng Shengdi again, Wang Zhuo found that it seems that the sisters are developing in the direction of Hong Kong's most famous NV singer group, the older one is developing in the direction of charm and gentleness, Xiǎo's height is gradually prominent, and the xìng grid is also naughty and hearty, and it seems that even the body shape is also the kind of one that does not convex in front and does not warp in the back, which is compared with An Qi.

After thinking about it, he asked, "Shengdi is almost fifteen years old, right?" Has your birthday passed? "Come on, there's still half a month. Meng Shengdi replied as she bent down to observe the row of xiǎo white rats in strange states on the experimental table.

Those xiǎo white rats have all been injected by Wang Zhuo recently, in fact, some of them have died and been dealt with, and the rest have seizures from time to time, some are lazy and don't like to move, some are as active as Sun Wukong, and some act as if nothing has happened, and they behave normally.

Shao nv with his arms on his cheeks lying on the table, his slender body in a wide white coat, there is really nothing to look at, xiǎo skillful ass has not yet become féi big due to the maturity of age, and it is still very medium.

Wang Zhuo smiled dumbly, Taoyuan people also have the custom of being born even if they are one year old, Meng Shengdi is only fifteen years old in half a month, so counting, isn't she now less than fourteen years old?

No wonder I didn't have any impulses for her, it turned out to be because of her age...... A young man who has been getting more and more greedy lately explains this to himself, but at the same time he is thinking back to the uncovered scene he saw when he was soaking in the hot springs together in Taoyuan.

"Angry!"

When his body reacted quickly, he hurriedly cleared his throat and stopped recalling, and said to Meng Shengdi: "Go back and help your sister work, the laboratory has an impact on the growth of the child's body, don't stay here for long." ”

Sending away the green fruit that could not be eaten, Wang Zhuo tidied up the pants that had become uncomfortable due to standing up, and let the strength become upright, which made it a little easier.

There was a wind chime, and then there was a crisp sound of brisk high heels, Wang Zhuo swept outward with his see-through eyes, and he was immediately happy, the secretary of the beautiful NV finally came back!

"When you're late for half a day!" He walked out of the lab with his hands in his hands and pointed at the secretary of the United States with a smile.

Fu Xinran's pretty face was moistened by sweat, she smiled, and raised the paper bag in her hand: "I brought freezing points back." After a while, the four of them sat around the sofa to eat freezing snacks, and Fu Xinran bought a lot of them, and sent some more to the freezer. The weather was so hot that the freezing point she bought on the ground floor of the building turned into Microsoft's after taking the elevator to the office, and if it was a few minutes late, it would have become a soup.

"What about Mei Shi, how did you send it away?" , Wang Zhuo asked with a smile.

Fu Xinran hesitated for a moment, signaled Wang Zhuo with his eyes, and said inconveniently in front of the two xiǎo girls.

Wang Zhuo rolled his eyes, dragged her to the compartment where the files were stored, confirmed that the sisters outside couldn't hear her, and urged her to speak quickly.

Fu Xinran looked out for a moment, and then whispered with an ambiguous expression: "I took him to our company's business department for a turn, and I shocked him at that time, and then said to him, I want to support him!" "Huh? Wang Zhuo couldn't cry or laugh: "Then what did he say?" ”！！
