When he and An Xue were fighting each other before, Yang Tian had been in the first row for a while, and Han Bing was diagonally behind him, he was sure that there was no one in the two positions around Han Bing. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

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 a short-haired girl next to her.

Yang Tian stared at the girl for a long time, and always felt that this back was a little familiar.

As if sensing her gaze, the girl suddenly turned around and met her eyes directly. Looking at each other, Yang Tian was slightly embarrassed.

This stared at other people's girls for a long time for no reason, and was arrested, how to look at it.

The girl didn't feel abrupt at all, she actually laughed, and even waved her hand at Yang Tian. Yang Tian had no choice but to wave his hand awkwardly.

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

This girl is incredible!

So many young and vigorous men failed to catch up with Yang Tian, but Xie Xin did it! Not only that, but it also lasted three laps!

Although Yang Tian was immediately overtaken after the system launched an arc attack, for an 18-year-old girl, this kind of physical fitness was terrifying 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 what this tough girl is called, because he saw her punching bags with his own eyes.

There is a row of covered spaces under the grandstand in the school playground, in which two sandbags for students are hung, Yang Tian wanted to test his strength before, so he tried to hit it, and the sandbags shook quite satisfactorily.

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

"Hello, my name is Xie Xin, let's practice?"

Yang Tianna turned his head and left.

Just kidding, the girl kicked the sandbag much more than herself just now, and the shaking amplitude was at least 1.5 times that of herself!

Moreover, with that eager look, Yang Tian would not agree to practice with her even if he made a decision with his knees!

As a boy, it is one thing not to beat a girl, and on the other hand, it is not necessarily that you can't beat it......

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

These two girls are one in the ice and snow, the other is terrifying and violent, how do you look at it and don't get along, how did they get together?

Yang Tian didn't understand.

Otherwise, what about a woman's heart? For women who have to go to the toilet together when they are close, and all kinds of torn species are a little trivial, Yang Tian said that he really can't start.

Well, let's study hard!

Immediately lean on the table and close your eyes and enter the study space.

Excluding the one class hour spent on Tai Chi Tui yesterday and the two class hours spent on experiments in the first three classes, Yang Tian still had 5 class hours left, which made him feel a little urgent.

This is the rhythm that will soon start to consume his miracle points!

However, what should be learned still has to be learned.

The first stage of the experimental tutorial mainly teaches the instructions and introduction of various experimental equipment, and several experimental templates are interspersed in the middle for Yang Tian to experience the process.

Yang Tian stretched out his hand to touch the light screen rising in front of him, and opened the second part of the experimental tutorial.

Yang Tian was rewarded with the "Matching Experimental Skills Training Set for the Basic Course of Professional Courses", in fact, this training set is also divided into four parts, each of which accounts for a quarter of the total proportion.

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

Yang Tian also glanced at the third part, which was temporarily in a gray state that could not be opened, and it was about the rules for the use of dissecting instruments, which seemed to be the knowledge that he needed to master until he took local anatomy.

As for the fourth part, Yang Tian simply couldn't see anything, and it was estimated that 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 that there are three three-dimensional icons of frogs, toads, and mice lit up in the options bar.

There are many dark icons, Yang Tian can roughly distinguish some, and the one following the mouse is obviously a rabbit, and the two long ears are easy to recognize.

Further back there were some strange things, Yang Tian could see what looked like fish, some looked like monkeys, and even saw winged ones.

A cursory sweep, everything that flies in the sky, runs on the ground, and swims in the sea is complete!

"System."

"Yes."

"Can these animals be used for experiments?"

"The system prompts 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 opened one by one according to the learning progress of the host."

"What about experimental animals and model organisms?"

Two nouns that he had never heard at all, Yang Tian was confused.

"Experimental animals, also known as laboratory animals in the broad sense, generally refer to all kinds of animals used for scientific experiments, which are animals that are raised in captivity, control the microorganisms they carry, and have a clear genetic background or clear source, and are used for scientific research, teaching, production, verification and scientific experiments."

To put it simply, it is an innocent family with a clear foundation, and the top three generations are all well-rooted animals, 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 gray mice that haunt the shadows in daily life, but the "albino" mice that have been raised in the laboratory, that is, the mice and mice that are often referred to as mice, with white fur and red eyes.

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

In addition, toads, frogs, etc., which are commonly used, are also the most cost-effective, 14 pieces of a toad, which is an animal that can be affordable by Oriental Medical University, so Yang Tiancai can successfully unlock it.

As for rabbits, the price is rising gradually, and Yang Tian can't touch it for the time being.

Many people also have a misconception that they don't know, that is, they think that the rabbit's coat color is originally white, but in fact, the real situation is that the rabbit's coat color should be gray, and the white hair is also because of albinism, which is the same as the white mouse.

Albino rabbits have long been used in eye irritation tests, also known as the Driz test, to ensure the safety of cosmetics and private products.

In addition, it can be used for various drug experiments, and because rabbits are larger than mice, they are easy to control, and they are also able to produce large amounts of antibodies, making them ideal for the production of polyclonal antibodies.

Further up, there are monkeys and chimpanzees, which are even more expensive and controversial, and if Yang Tian only stays at Oriental Medical University, he is afraid that he will never be able to get in touch with them.

However, the system has such an option, maybe it will be used in the future.
