"Mother, the shower is so easy to use, and it can also make rainbows! Sister Jingjing led us to create a lot of rainbows. She really knows a lot of things. ”

Li Lizhi was very envious of the Qiaohu shower in Niu Yingxiu's hand, and felt that the shower was both beautiful and easy to use.

When she is not with Niu Yingxiu, she must be very careful when watering.

Empress Changsun asked in detail, it turned out that a few days ago, the thing Niu Yingxiu was carrying in her hand was called a shower.

"Let the young superintendent help you make a few."

"The young eunuch can only make wood or iron, and there is no way to make it as light as Yingxiu's hand." Li Lizhi whispered. There was a little complaining in his tone.

But her mother doesn't like them to force other people's objects, otherwise, she really wants to take the initiative to ask Yingxiu.

"Instead of wood and iron, do you want to use pottery?"

"Mother, Yingxiu is so light, she can lift a big bucket alone."

The wind was blowing, and she carefully guarded her flower pots.

"What is that made of?" Empress Eldest Sun asked casually.

Sister Jingjing said that it was the mysterious material of the Water Cloud Palace, and she didn't know how to make it. The advantage is that it is very light. However, Shuiyun Palace has not done much, and it is said that because it is not perishable, it is regarded as a bad omen by Shuiyun Palace. ”

"It's not perishable, it's obviously a good thing, but the people of Shuiyun Palace don't seem to be very knowledgeable."

At this time, Empress Eldest Sun had a strong interest in the Shuiyun Palace in Fan Jingjing's mouth.

The savages in this place seem to be unusual, and they have too many tools and knowledge that the Tang people have not yet mastered.

Where exactly is the Water Cloud Palace?

It seems that before she appeared at Niu's house, no one saw her.

But it is also unreasonable to say that she was originally in the Niu family manor.

Before, Fan Jingjing did not show value, but the objects in front of her all said that she was a very valuable person.

When Empress Changsun was still thinking about it, Li Chengqian did not give up telling Empress Changsun what he saw.

Seeing the rapid rotation of the windmill, it seemed a little unbearable, and the eldest grandson queen said:

"It's windy here, and it's hard to talk, so let's go inside and talk!"

A few people changed to a pavilion with less wind, there was a small artificial bridge in front of the pavilion, the palace maid served some seasonal fruits, and several people said while eating the fruits:

"Fan Jingjing's method of farming is not the same, although she has not actually seen the final results, but I think that after she raises seedlings first, although it will be more troublesome to sow seeds, but Sister Jingjing said, so as not to waste land, each crop, the space needed is different, too dense will not grow good, too loose, and waste space.

Not every seed sprouts.

After the seeds are determined to germinate, the seeds are planted in the field, arranged neatly, and made in the most dense way according to the space required by each crop, so as to obtain the highest yield.

In addition, she also asked us about the method of fertilizing the land, and as a result, she asked someone to get fertilizer water, prepared a lot of straw stalks, and let the fertilizer water and the grass stalks be staggered together, let her ferment, and then report and put them in the field.

She asked the people in the palace and the Niu family to do this work, but they all felt that it was too dirty and refused to do it......

So she asked them to pay for it and asked someone nearby to do it...... This is obviously her job...... But she said that this is a royal estate, and she is doing things for the royal family......

And Niu Shijin is her boss, and the Niu family should help with things.

Otherwise, let Niu Shijin do it......

Thinking of Niu Shi's strength to pick up dung, I think the picture is very beautiful......"

The past few days have been enough for Li Chengqian and Li Lizhi to regard Fan Jingjing as an idol.

Although Fan Jingjing is not very good at being a person, she has a set of principles, and if you get used to it, you can find a way to get along with her from her principles.

Fan Jingjing has a lot of things in her head, and she can tell the truth about many things, unlike others, who always tell it with ghosts and gods.

These truths are very simple, but they can solve their doubts.

For example, using a shower to create a rainbow, she says is the principle of refraction of light.

Light is made up of red, orange, yellow, green, blue, indigo, and violet, which is the color of the rainbow.

"Mother, I want to do this experiment, you ask people to dye the cloth in these seven colors, I want to use a quick rotation to see if it really appears white.

By the way, she also said that the reason for the rain is that the water vapor in the air condenses and falls.

It's like when we put ice in a porcelain basin, but water comes out of it.

We've all seen these phenomena before, but we really haven't thought about why this is happening.

Or maybe we notice, but blame the ghosts and gods. ”

"By the way, Sister Jingjing said that the weather seems to be particularly strange this year, and there may be a drought near Chang'an, because he feels that the water vapor content in this place is very low, and it is best to prepare early."

Li Lizhen suddenly thought. She thought it was strange that there should be a little rain in the spring, but it didn't rain all the time.

"Is she trying to make excuses for the bad growth of potatoes, so that I don't have trouble finding her head?"

Empress Eldest Sun said with a smile. How can one know the changes in the heavens? However, she was still going to ask Qin Tianjian.

"I don't know, she also showed us the locusts in this place, there seem to be a lot of locusts, and they may have to burn the whole land before they can sow seeds, but the biggest fear is that the locusts will come from somewhere else, so they have asked us to start weaving nets to prevent these locusts from eating our leaves.

It's just that if you want to weave a more delicate net, the cost is higher than the cost of those crops......"

Li Chengqian interrupted Li Liqian and said.

"Mother, I think we still have to pay attention to Sister Jingjing's prophecy, because some of the signs she pointed out to us can show that this year may be a year of locust plague, but if that field wants to be preserved, it must really be covered with a net and all the eggs on the land must be exterminated.

She said that she also fought for potatoes.

In the past few days, our people have been instructed to collect weeds everywhere to dry, and then burn all the fields again to prevent the eggs from hatching in the soil.

But she said locusts would come from somewhere else, so that wasn't enough.

Anyway, as long as you weave a finer net, don't let the crops underneath be damaged.

She said that the crops she grows are not ordinary crops, and that when she first starts producing, she should be able to sell them for a good price, because if she has enough eyesight, the crops produced in this place should be popular. ”

"There are too many "should" and "maybe" in your words, which means that you are not sure, as for the locust plague is a make-up lesson, whether it is possible to happen, we may have to ask the relevant officials, and I will pay attention to it when the time comes, you go to play, and come back to report to me if you have any observations. ”
