Chapter 68 The Tough Xie Xin

When he and An Xue were fighting each other before, Yang Tian stayed in the first row for a long time, and Han Bing was diagonally behind him. He was sure and sure that there were no people in the two positions around Han Bing. .

After all, the goddess of ice and snow is too cold for ordinary people to approach.

But now, Han Bing is still sitting in her old seat in the second row, but there is an extra girl with short hair next to her.

Yang Tian stared at that girl for a long time, and always felt that this back figure looked familiar.

As if sensing her own gaze, the girl suddenly turned her head and met her own eyes.Looking at each other, Yang Tian was a little embarrassed.

This stared at other girls for a long time for no reason, and was caught in the act, no matter how you look at it, you feel guilty.

The girl didn't feel that Yang Tian was abrupt at all, she just smiled and even waved at Yang Tian.Yang Tian could only wave his hand awkwardly.

No wonder I always feel that her back is familiar, I know her, Xie Xin.

This girl is amazing!
So many young and energetic men failed to catch up with Yang Tian, ​​but Xie Xin did it!Not only that, but also persisted for three full laps!

Although Yang Tian was overtaken immediately after the system launched the arc attack, but for an 18-year-old girl, this kind of physical fitness is scary enough.

Running together can make Yang Tian have an impression of her, but it can't make Yang Tian remember her name. Yang Tian really knows the name of this tough girl because he saw her hit the sandbag with his own eyes.

There is a row of covered spaces under the stands of the school playground, in which are hung two sandbags for students to use. Yang Tian wanted to test his strength before, so he tried to hit it. The shaking of the sandbags was satisfactory. .

Unexpectedly, Xie Xin jumped out from the side at this time, straightened the sandbag, and then kicked it...

"Hi, my name is Xie Xin, shall we practice?"

Yang Tian turned his head and left.

Just kidding, that girl kicked the sandbag much harder than me just now, the shaking range is at least 1.5 times that of my own!
Moreover, with that face eager to try, Yang Tian would not agree to practice with her even if he made a decision on his knees!
As a boy, it is one thing not to hit a girl, but on the other hand, it is not necessarily true whether you have ever hit a girl...

Seeing Xie Xin smiling happily at him, turning his head and half his body towards Han Bing as if he was saying something, Yang Tian felt a ball of sadness.

One of these two girls is icy and the other is terrifying and violent. No matter how you look at it, they don't get along. How did they get along?
Yang Tian didn't understand.

How about a needle in the bottom of a woman's heart?For women who have to go to the bathroom together when they kiss, and who are all kinds of annoying for a little bit, Yang Tian said that there is really no way to start.

Well, let's study hard!
Immediately lie down on the table and close your eyes to enter the study space.

Excluding the one class hour spent yesterday on Tai Chi push hands, and the two class hours spent on experiments in the first three classes, Yang Tian still has 5 class hours left, which gave him a little sense of urgency.

This is the rhythm that will soon start to consume his miracle doctor points!
However, what should be learned still needs to be learned.

The first stage of the experimental tutorial mainly taught the instructions and introductions of various experimental equipment. Several experimental templates were interspersed in the middle to let Yang Tian experience the process. After eight hours, he was familiar with all the experimental equipment.

Yang Tian reached out and touched the light screen raised in front of his eyes, and opened the second part of the experimental tutorial.

The reward Yang Tian received was "Matching Experimental Skills Training Set of Basic Courses for Professional Courses". In fact, this training set was divided into four parts, each of which accounted for a quarter of the total weight.

The second part is animal experiments, including the introduction of various experimental animals, simulation, introduction of grasping methods, introduction of handling methods, etc., as well as several supporting small experiments.

Yang Tian also took a look at the third part, which is temporarily in a gray unopenable state. It contains rules about the use of anatomical instruments. It seems that it should be knowledge that he will not need to master until he has studied regional anatomy.

As for the fourth part, Yang Tian simply couldn't see anything, probably the system didn't want him to learn it for the time being.

Then learn what you can learn first.

The animal experiment part is actually incomplete. Yang Tian can see three-dimensional icons of frog, toad, and mouse lit up in the option bar.

There are many hidden icons, and Yang Tian can roughly distinguish some of them. The one behind the mouse is obviously a rabbit, and the two long ears are easy to recognize.

Afterwards, there are some weird things. Yang Tian can see those that look like fish, some that look like monkeys, and even some that have wings.

With a cursory glance, everything that flies in the sky, runs on the ground, and swims in the sea is complete!

"system."

"exist."

"Can these animals be used for experiments?"

"The system reminds the host that the data provided by the system includes both experimental animals and model organisms, covering all the needs of the host at all stages, and will be released one by one according to the host's learning progress."

"What are experimental animals and model organisms?"

Yang Tian was confused by the two terms that he had never heard of before.

"Experimental animals, also known as experimental animals in a broad sense, generally refer to various animals used for scientific experiments. They are artificially raised, and the microorganisms carried by them are controlled. The genetic background or source is clear. They are used for scientific research, teaching, and production. , testing and scientific experiments of animals."

To put it simply, it means that the net worth is clean, and the bottom line has been figured out. For more than thirteen generations, they are animals with good roots, which are specially used for scientific experiments.

Among them, rats and mice are the most, accounting for nine tenths of the number of experimental animals.

The mice here are not talking about the grayish-looking mice that appear in the dark in daily life, but the "albino" mice that have been raised in the laboratory, which are often called small white mice and big white mice. fur, red eyes.

Mice are suitable for research on human genetic diseases, while rats are more suitable for cancer research and toxicology experiments.

In addition, toads, frogs, etc. are commonly used. These three animals are also the most cost-effective. A toad costs 14 yuan, which is an animal that the Oriental Medical University can afford, so Yang Tiancai was able to unlock it smoothly.

As for the rabbits, the price keeps going up, and Yang Tian can't touch them for the time being.

Many people still have a misunderstanding, that is, they think that the fur of rabbits is originally white. In fact, the real situation is that the fur of rabbits should be gray, and the white hair is also due to albinism, just like white mice.

Albino rabbits have long been used in eye irritation tests, known as the Dritz test, to ensure the safety of cosmetic and personal products.

In addition, it can also be used in various drug experiments. Because the size of rabbits exceeds that of mice, it is easy to control and can produce a large amount of antibodies, so it is the most ideal mammal for the production of polyclonal antibodies.

Further up, there are monkeys and chimpanzees, which are more expensive and controversial. If Yang Tian only stays at the Oriental Medical University, he may never be able to get in touch with them.

But the system has such an option, maybe it will be useful in the future.
