"You should understand the fragility of children, we must protect them well, and we must not act recklessly."

Ye Hanxuan knew that Zhang Chuchu should have been dazzled by the success in front of him, so he made such a low-level mistake.

"Princess, please rest assured, I will definitely be cautious, such a mistake will never happen a second time.

When I'm 100% sure, I'll give it to the two little masters. ”

Zhang Chuchu nodded solemnly, and then left with a straight face and continued the drug test.

"Princess, licorice and I still have to test the medicine."

Zhang Chuchu left, Shi Zhu thought about it, and said firmly:

"Princess, in the next few days, I will arrange other maids for you to serve you.

There's still a deer chirping next to you, and for a while, there's no big problem. ”

Caryophyllum is not afraid of death, so he is in such a hurry to test the medicine, and Shizhu's plan is deeper.

The word "test" is there, which proves that the drug still has a certain degree of danger.

Shi Zhu felt that if her princess wanted to test the medicine, she must want to set an example and show the world with an attitude.

In view of the relationship between the two little masters, this matter of testing the medicine naturally cannot let the princess go.

But she and Licorice are the people next to the princess, and they go to test the medicine, and they also go on behalf of the princess.

In this way, no matter how many mouths the world has, there should be nothing to say.

"It's fine."

It just so happened that Lu Ming also had this plan, and when he heard Shi Zhu's words, he responded.

Of the three of them, there must be one or two.

Caryophyllum and Licorice were willing to take the initiative to go, but it made Lu Ming have one less thing to worry about:

"Princess, this matter is settled."

Seeing that the three maids had discussed it, even if Ye Hanxuan believed Zhang Chuchu's words again, he could only come down.

What's more, after taking care of the child for more than a year, Ye Hanxuan suddenly left the child's side, and Ye Hanxuan couldn't adapt to it.

After taking the medicine, Ye Hanxuan was a little safer, and she had to not be able to see the child for at least seven days.

Don't say whether the child is willing or not, Ye Hanxuan thinks about not seeing the child for seven days, and her heart is very uncomfortable.

"It's fine."

In line with this plan, Ye Hanxuan naturally responded.

Caryophyllum and licorice went to Zhang Chuchu to try the medicine, and as soon as this situation appeared, it was indeed a lot more reassuring for more people who came to test the medicine.

What is the status of licorice and caryophyllum around Ye Hanxuan, many people still know.

Zhang Chuchu was the first person to test the medicine, so when it was used on licorice and caryophyllus, Zhang Chuchu still had a good handle.

In order to test safety, anyone who tests the medicine will live in a separate room for a few days to see how it reacts.

As for the child, because of Ye Hanxuan's reminder, Zhang Chuchu didn't use it on the child right away, and he wanted to study it again.

It wasn't until Zhang Chuchu considered it several times and determined the amount that he dared to use it on the child's body.

The trial period lasted for about half a month, and it was not until half a month later that the smallpox and chickenpox drugs were officially activated.

And the first batch of people to use this medicine were none other than the soldiers who were going to follow the fourth master on the expedition this time.

Unlike the soldiers of the Yu Dynasty, the nomadic people have the most contact with cattle, horses and sheep.

Ye Hanxuan clearly remembers how the original vaccine came about.

That's because some people have seen that those who are in frequent contact with cattle and have obviously contracted cowpox, but they don't have a particularly big reaction.

Eventually, anyone who has ever contracted cowpox will not have smallpox again.

This was the beginning of the smallpox vaccine.

So, with regard to the infectious disease of smallpox,

The possibility of Dayu dying is much higher than that of nomads.

Coincidentally, Jin Fengguan was making smallpox.

Although there are not many people who are infected, there is a certain danger in the end.

Of course, the reason why the emperor sent the fourth master to Jinfeng Pass at this time has something to do with this smallpox.

The emperor originally thought that although the fourth master was cured by Ye Hanxuan, he would not die early.

No matter what, Ye Hanxuan is just an ordinary person, and her medical treatment is limited.

Ye Hanxuan can research a prescription for treating the plague, can he also research a prescription for smallpox?

If this is the case, then Ye Hanxuan is really the first person in hundreds of years!

Moreover, at the beginning, the emperor only planned to let the fourth master come to Jinfeng Pass alone.

Not to mention whether Ye Hanxuan can think of a prescription for treating smallpox, the fourth master is always a mortal.

In Jinfeng Pass, maybe none of them made a good fuss, and the fourth master also contracted smallpox.

In this way, even if Ye Hanxuan knew the news and really studied it,

Waiting for Ye Hanxuan's prescription to arrive, as soon as the news came, the fourth master should also die of illness in the time when Fang Zi was gone.

How would the emperor with this kind of thinking know that everyone in the world may get smallpox,

Only he and the fourth master, two people who have never been infected with smallpox, will not be infected with smallpox in this life.

Smallpox is also viral, and the fourth master and the emperor have used pearl fruit.

So just smallpox, it really can't hurt the fourth master.

Ye Hanxuan understands the situation of the fourth master.

Smallpox can't help the fourth master, but it is the people who have to fight with the fourth master.

In order to appease people's hearts, Ye Hanxuan asked the fourth master to also use medicine.

In front of everyone, the fourth master casually took out a pack of many medicines and used it.

The fourth master has this attitude, so the other soldiers have nothing to doubt and hesitate.

"You say, after taking this medicine, we really won't get smallpox and chickenpox in the future?"

The soldier who used the medicine still had one hand on his heart, and he only thought it was incredible.

Originally, he came to fight just for that little military salary and wanted to feed his family.

Before, he thought that if he was lucky, he might be able to return from the battlefield.

However, as soon as smallpox appeared at Jinfeng Pass, the soldier was ready to die at Jinfeng Pass.

But at this time, Ye Hanxuan injected vitality into Jin Fengguan, which had already appeared dead.

It is precisely because of this that so many people in Jinfengguan can't accept it, the happiness and luck that fell from the sky.

"Do you know who is working on this drug?"

The other soldier snorted, saying that this person was really rare and strange, and this person had not yet understood how blessed he was this time.

"Who, I heard that it's just a woman?

I still doubt it, is it reliable for girls to do things? ”

The soldier before said disdainfully:

"By the way, this medicine just came out, I heard that you were the first to sign up to try the medicine, and you are really not afraid of death."

He still doubts whether this medicine is really useful, this brother has long wanted to try the medicine.
