One of the drugs that Xu Nan is developing now is a fetal drug.

In the pharmaceutical market, there are countless types of fetal drugs. However, there are not many that can be completely harmless to the body of both the child and the expectant mother, or even very few.

After all, in the whole world of medicine, Western medicine, not Chinese medicine, is popular.

The characteristic of Western medicine is that it works quickly, but the side effects are relatively large.

So Yang Xiaotian thought of a prescription he saw in an ancient medical book, but because it was defective, there were a few flavors of medicine, and Yang Xiaotian could only provide one or two words.

And if you want to completely restore the entire prescription, you must at least look through hundreds of herbs with similar names. And choose dozens of them with the most suitable effects - after all, there are some herbs that have similar names and looks. Even in terms of medicinal properties, there is little difference.

It's hard to spot the difference between them without a careful comparison.

And Xu Nan is not a person who likes to be soft, otherwise, it would be impossible to fight with Song Qingshan for more than ten years.

Since Song Qingshan set off, she has been trying for more than a month.

For the development of new drugs, a month is naturally too much. However, knowing most of the medicinal materials and the proportion, you only need to add the remaining medicinal materials to it according to the proportion through continuous attempts, and you can configure this medicine.

And during this distribution ratio and continuous experimentation, Xu Nan discovered that traditional Chinese medicine would be so magical. The same herbs, different proportions, can have different medicinal effects.

This made Xu Nan very interested, and at the same time, he also admired Yang Xiaotian even more in his heart.

In terms of Western medicine, simply looking at the series of records created by Yang Xiaotian in Stanford University School of Medicine is enough to prove a lot.

And now Yang Xiaotian casually said a prescription, if you want to configure it, it will take so much effort. This made Xu Nan can't help but think about how much effort Yang Xiaotian spent on the development of Tianle Powder when he first developed it.

"Okay, don't be a nymphomaniac, hurry up and prepare the medicine, I'll use it. It was Carolynska who spoke, she was not young now, and when she gave birth to her first child, she was already a little dangerous.

But in the end, Carolynska decided to have another child, because she didn't want her child to play at home without a playmate.

"Teacher, can you not worry...... All...... It's a mom of a child. Carolynska was pregnant a little earlier than Xu Nan, but the speed of recovery was not as fast as Xu Nan.

The slender and graceful beauty doctoral supervisor at the beginning has now become a middle-aged woman with a bloated body. Pregnancy can make a big difference to a woman.

The figure can be slowly recovered later, but a few years ago, Carolynska was already in her thirties, and after three years, she was only two or three years away from turning forty. If a woman has a child after the age of 40, the danger is very high.

So Carolynska finally decided that after having another one, she would never have any more children in the future.

And after knowing that Xu Nan had developed a fetal pill, she naturally wanted to try it to see how it worked.

After all, she is older now, and although the child in her belly is only a few months old, Carolynska always feels that the little thing in her belly is not particularly honest.

And as a doctoral supervisor in medical school, for the most common drugs on the US market now, although the effect is very good. But the hormones in it, although after years of research and development, have reduced their effects on the body to the point of almost nothing.

But now Carolynska is not a little girl, and she naturally does not dare to take risks. Even the slightest danger she didn't dare to try.

Of course, she is only about four months pregnant now, and she is still far from the time of labor pain.

The reason why I feel the pain now is only because Carolynska cares too much about the child and is nervous. Under the tension, the illusion generated by the body is just that.

Xu Nan understands this, and Carolynska, as a medical doctor supervisor, naturally does not understand.

It's just that there are some things, even if you know them, you can't avoid being afraid. Especially when things happen to you, this panic is even more difficult to control.

Even Carolynska is not exempt from liability as a doctoral supervisor at the medical school.

In the final analysis, it is a sentence - pity the hearts of parents in the world.

"Now this has just been successfully configured, and the taste and color are exactly the same as what Brother Xiaotian said. But this has not been tested. I know that you are nervous and unwell, and I also trust the medicine that Brother Xiaotian said. But in China, there is a saying that medicine is three parts poison. On the one hand, the reason why Carolynska is so anxious is that the fetus in her womb makes her a little uncomfortable.

On the other hand, for Yang Xiaotian, Carolynska is completely trusted.

Although the person who decocted the medicine was Xu Nan, but the prescription was given by Yang Xiaotian, after seeing the happy expression on Xu Nan's face, Carolynska naturally subconsciously thought that Xu Nan had completely succeeded.

Although she wants to have a child in her heart, she has only given birth to a child after all.

The pain of childbirth can even be screamed in pain even by Xu Nan, who has been licking blood on the knife for a long time, and Song Qingshan, who thought that just after seeing Xu Nan's image, she was directly scared to break off the idea of having a child.

Carolynska was actually in pain to death, and under Claure's care, she rarely even got sick. Especially after getting married, although she often goes in and out of the hospital, because of her good health, she has too few opportunities to endure pain.

Although all doctors understand how painful labor pain can be, after all, there are many things that only those who have truly experienced can truly understand the deepest truth of the matter.

Just like a woman with menstrual cramps, most of the men's advice is to drink more hot water. Because in their eyes, it's just a very casual little thing.

After all, they have to come every month, and in the eyes of most men, this should be something that has become a habit. So at least nine out of ten men don't understand how their girlfriends behave as if they had suddenly changed when their period came.

As for the pain of childbirth, as long as you have watched the video of a woman giving birth to a child, although it is still impossible to experience it personally, you can still feel how painful it is.

After giving birth to a child, the kind of heart-rending pain, as if tearing her body in half, made Carolynska find out that she was pregnant again.

Except for the surprise at the beginning, as long as I have leisure time, I will be in an extremely nervous state.

After all, I have only given birth to a child for more than a year. The heart-wrenching pain that Carolynska could wake up from her sleep in fright, even when she dreamed of that scene.

Not to mention experiencing the pain again.

And Yang Xiaotian said, this prescription, in addition to being able to stabilize the fetus, is also to nourish the mind and regulate qi.

For Carolynska now, she has basically done everything she needs to do to have a baby. And now, the only thing she wants to do, and what she hopes to do the most, is to calm her nerves.

Medicines that can calm her down and not have any adverse effects on the development of the fetus in her womb are what she desperately needs now.

"Then you as soon as possible, dear Xu. This little guy must be a little devil. He's starting to hang out in my * right now, and I feel like he might have been a good boxer in his last life. Otherwise, I wouldn't be taking my * to steam out all day long. Carolynska stared wide-eyed and looked at Xu Nan very seriously.

"Uh...... Well, I'm going to do the experiment now. I'll reply to you in three days...... "Xu Nan wants to laugh, after all, the little guy who is only two or three months old, although he has already taken shape, he has not yet grown into a human form. It's possible to be able to swim, but to say that he's hanging out here and there is pure.

And the scene that Carolynska describes in this eloquent rhetoric is actually only caused by her own nervousness.

As long as she relaxes a little, she won't feel this way at all.

It's a pity that not everyone can be so indifferent, just like if she gets pregnant again, Xu Nan will definitely give birth again. And she doesn't plan to do any contraceptive measures, on the one hand, she doesn't like the feeling of being blocked. On the other hand, it is because of the agreement made with Xu Xiangtian.

If they have two children, hopefully one of them will be surnamed Xu.

Although Xu Xiangtian also has a son, compared to Xu Nan, the gap between them and Xu Nan is too obvious. If they were to become the heirs of the Xu family, to be honest, Xu Xiangtian was really a little relieved.

"That's good, let's go. Carolyn Ska is more anxious than Xu Nan.

"Good, good...... I'll go ...... now" Xu Nan, who originally wanted to take a little rest, smiled bitterly, then turned around and went to the laboratory with the freshly fried medicine.

Xu Nan has also applied for a supervisor now, but after all, she is still young, and although her grades are also excellent, she still can't reach Yang Xiaotian's level, which is enough to surpass the vast majority of doctoral supervisors in the whole college.

So she applied not for a doctoral supervisor, but for a master's supervisor.

"Hiss......" Suddenly, Xu Nan frowned, as if someone had stabbed him in the heart.
