Arati shook her head.

"The Artemisia annua seedlings have sprouted."

Scared to death!

Ning Wuxian breathed a sigh of relief, and then thought about the reason why Alati was depressed, and he couldn't be happy when he heard this good news.

He pondered for a moment and asked Ala, "How many Artemisia annua seedlings grow?" ”

"Master Hua brought a total of 22,000 seeds, and 20,000 plants grew."

With such precision, it can be seen that these seeds were originally counted by the Chinese master one by one.

As long as Artemisia annua seedlings can grow, they can basically survive.

Ning Wuxian said to Arati: "I can't go to the imperial tomb to worship Huashi for the time being, you dig two Artemisia annua seedlings and plant them next to Huashi's grave, so that he can also see them." ”

"Will this work?"

Don't look at Arati as a Qiuzi person, but he still knows the customs of the Daxing people very well.

Especially because he was coming to the capital, Qiu Niang also specially found him a book about the taboos of the royal family.

The imperial mausoleum is an important place for the royal family, can he enter it one by one?

"Yes, you take the greeting post I gave to Miss Shen and ask her to take you in."

Hua Sheng did not see the prosperity of Artemisia annua growing in Huangzhuang before his death, so he let Artemisia annua take root in his resting place from then on.

Soon after.

The use of Artemisia annua formula to improve the merit of curing dysentery will also be sent to the grave of the Chinese teacher.

If he can extract Artemisia annua juice, he will also name it after Huashi.

Ning Wuxian waited for the third brother to move the small desk and simply wrote a few words.

He didn't need to explain much, I believe that Shen Youchu knew his arrangement, and he would understand what he was thinking.

"Go ahead."

Arati took Ning Wuxian's letter, didn't even carry the envelope, and didn't care about lunch, so he hurriedly roared towards Shen's house.

Learned that Artemisia annua grows.

Ning Wuxiao had something to do in the afternoon.

He asked Yun Fei to take out the glass bottle he had tried to make last time and put it on the kitchen stove to roast it.

"Childe, how do you bake it?"

"Roast like a roasted sweet potato, remember to take an iron clip and stay away from it."

"Why?"

"It's going to blow up...... It's just to stretch it up like boiling water. ”

In this era, gunpowder has not yet come out, and Yunfei is still at a loss for the word explosion.

But he has encountered the matter of boiling water to open the lid of the kettle, and he once burned his hands by the heat when he was a child, and he still remembers it vividly.

Hearing Childe say that baking a glass bottle was so dangerous, he didn't dare to be careless.

When I got to the kitchen, I found the longest iron stick and put the glass bottle in the matchstack to bake.

Who knew that after baking for half an hour, the glass bottle did not break.

Just when Yunfei was about to fall asleep next to the warm boiler, the matter of baking the glass bottle finally stopped.

Although the glass bottle was not fried, it was much darker on the outside, and it was covered with a so-called sealed cap, and a lot of ashes floated into it.

"It seems that the quality of this batch of glass bottles is still good."

It's just that the tightness is not up to the standard of the experiment.

In fact, Ning Wuxian only stayed on theoretical knowledge about the extraction of Artemisia annua juice.

For the specific operation method, he also knows six out of seven - none of them.

I can only rely on my memory to do experiments in middle school, first restore the flask, beaker and sealer, and finally consider the means of purification.

This is called, the soldiers and horses have not moved, and the grain and grass go first.

Fortunately, the firing of glass bottles is about to become the most profitable project in the royal firing of glass.

More improved products will appear in the future.

The texture of the glass bottle is not crispy, and it is already very good that it will not be baked and fried at any time.

Be content.

In this state of mind, Ning Wuxian drew a few more sets of sealing hoses, and after Zhou Jingxian returned home, let her take them to the Ministry of Industry to try it out.

Rao is Zhou Jingxian, who has been groping in the Ministry of Industry for many days, and thinks that she is almost familiar with the original village materials of the Ministry of Industry.

After seeing that the hose on the drawing still marked its purpose, the monk who was still Zhanger was puzzled.

It's a novelty.

It's hard to understand.

"Mr. Ning, what are these things made of?"

"Hose hoses, of course, are made of glue."

It's not that Ning Wuxian hasn't considered the intestinal tube.

But that thing is unused, and it doesn't seal well.

It's time to put the Ministry of Works to the test.

Zhou Jingxian was even more blindsided.

"Glue?"

What is it?

Ning Wuxian had to give an example, saying that he had seen rubber trees on a merchant ship coming from the south in Jinling Mansion and said it.

"Rubber trees? I really haven't seen it. ”

Not to mention that Zhou Jingxian has never seen it, Ning Wuxian has not seen this thing since he came here.

It is estimated that today it is just a tree.

Therefore, no one will take it thousands of miles from the "ends of the earth" to the interior.

"This kind of tree grows on the coast of the South China Sea, you can send someone to ask, the place where this kind of tree grows is closer to King Kang's fief."

In order to avoid Zhou Jingxian looking around like a headless fly, and the name of this tree is not called this name because the rubber was not found before.

He used his modest drawing skills to draw the shape of a rubber tree on paper.

"Just look for it like this, look at it the same, and take a piece of the tree for me and send it over."

"Since Mr. Ning said that he had seen it, there must be such a tree, so I will send the drawings to my father's mansion and ask my father to send someone to the south of his fief to find it, but it will take a lot of time to come and go."

Hose development is a long process.

Ning Wuxian didn't expect it to be completed overnight.

"Don't worry, you let people look for it slowly."

If he can't find it, he can only think of other ways to purify.

If it really doesn't work, after squeezing the juice, consider adding other items to make a way to precipitate and remove impurities...... Although he had never even heard of that method, he could only cross the river as a blind man feeling the stones.

But as long as the spirit of research is there, and we have been groping our way forward, sooner or later we will be able to get the desired results.

"Mr. Ning is not in a hurry, my father will also be in a hurry, I will go to my father."

Zhou Jingxian mentioned it casually.

But inadvertently, it revealed King Kang's attention to Ning Wuxian.

After Zhou Jingxian left, Ning Wuxian stared at the white paper on the table for a long time.

It wasn't until the sun outside the window slanted westward, sprinkling a golden afterglow on the paper, that he came back to his senses and said to himself: "Speaking of which, tobacco is the most suitable thing to be produced in Lingnan, tobacco seeds have been sent to the capital for two months, and they can't germinate elsewhere, so they should germinate in Lingnan." ”

When the time comes, I would like to propose to His Majesty that the four seasons of Lingnan are like spring, so that tobacco can grow in Lingnan for a few more seasons.

It should be able to increase some taxes and revenues for King Kang.

Besides.

The name of the tobacco growing area may not be useful in the first year, but when it comes to the treasure land in Lingnan, it will take less than half a year to plant the second batch.

In less than a year, all the people of Daxing will know how King Kang's fief has changed from a poor countryside where birds don't to a place where every inch of land is worth every inch of the prince.

The conscience of heaven and earth.

He is doing this for the sake of great prosperity, for His Majesty to increase taxes and raise cavalry, but not for King Kang.

Just thinking about it, the housekeeper Jinzhong stood at the door and whispered respectfully.

"Lord Ning, the prince of Jin Wangfu Yu Shizi asked to see, saying that he didn't understand the glass bottle during the competition, how to use it, and specially came to ask the adults to give advice."
