The plan all let those eyeliners go, and sure enough, in the past two days, Qingyu Pavilion has calmed down a lot, and it seems that he should have believed their plans and news.

They didn't dare to blatantly oppose Qingyu Pavilion, so they were bound to do it quietly, so that Qingyu Pavilion's secret actions would not be detected by them.

Xi Duyun felt the thrill of the past few days, and became more and more worried about Qi Lichen's safety.

On this river and lake, every step may be an abyss, and there will be no return.

Fortunately, the letters will be sent back through the flying pigeon.

Xi Duyun looked at the vigorous and powerful big characters on it, and felt a little relieved in his heart, this is his font, the font is vigorous, it seems that it should be good, full of food and good clothes.

After Xi Duyun replied to the letter, he went to the greenhouse he made, surrounded by a thick felt cloth, and used the glazed tiles brought back by Qi Lichen, which really had excellent lighting.

I felt the temperature, just right, neither cold nor hot, like a feeling of spring.

Xi Duyun knew that if she didn't do this experiment well next spring, then everything she had planned would not be implemented.

She first sent someone to ask the farmers for rice seeds.

She couldn't see anything, after all, she wouldn't have thought that she would need to use this knowledge one day in modern times, and she knew that in the library, she would have read more about hybrid rice.

But she knows that plants are also survival of the fittest.

She didn't know about the farmer's affairs, so Cuiyun asked the village chief.

There were several kinds of rice seeds, which she had collected from all over the world.

Although Nancun does not grow rice, the village chief is very clear about the attributes of these crops.

He introduced to Xi Muyun: "This seed is from the north, although it is drought tolerant, but the rice that grows is extremely shriveled, and the yield is very small, although our South Village is suitable for planting this kind of rice, but the yield is too small, it is not as affordable as planting melons, fruits and vegetables, which is also some places that can't grow melons, fruits and vegetables will plant this, and this kind of rice is usually planted in the south, although the yield is relatively high, but it is very drafty, we can't plant it in Nancun, and the other seven, seven, eight, and eight are just like that." ”

Xi Duyun looked at the seeds in front of him, and knew that the pollen hybridization of two rice seeds might make the rice drought tolerant and yielding high, but it didn't seem to be achieved overnight.

I'm afraid it won't be done this spring.

It's going to take years of experimentation, and luck is part of it.

Xi Duyun divided the plots of land into several parts, and then planted them separately according to the attributes introduced by the village chief of each seed.

The warm and humid environment is the most suitable for rice cultivation and growth, and if the problem of water source is solved, then this kind of rice, which is commonly cultivated in the south, can be planted in Nancun first.

In the future, we will see if we can increase the yield per mu of rice by changing the rice.

Xi Duyun made up her mind and planned to go to Nancun again.

At the foot of the mountain, there is a river, and according to the people in the village, they will also go to the river below to pick up the water.

Xi Duyun knows that in modern times, there are many ways to divert water from the lower places to the higher places.

Pumping machines are one of them, and there are also some pumping machines that don't require electricity, and she remembers that there was a TV show before, which was introduced in detail.

By the way, it seems to be on that water conservancy book as well.

Xi Duyun patted his head, he was really a pig brain, he thought that there would be no content in that book that he needed, and he didn't have a long memory.

But now that the books have been delivered, what should I do?

I can't come back.

Just thinking about it, Cuiyun came to report that Xi Duyu hadn't seen her for a few days, and she missed her very much.

Thinking of Xu Bubu or the people around Gu Jianglin, he might be able to ask Xu Bubu.

Xi Duyun immediately went back. Dede

The meal has been prepared, Xi Duyu is preparing the rice, she is always used to doing these things, and when she sees her, she looks very intimate.

Twilight rubbed her head, "How's your homework?" ”

"It's good, this kid has Huigen." Xu Buyi walked in from outside the door.

Xi Duyun looked back at him, "Aren't the Fifth Princes busy over there?" There's still time to get here. ”

Xu Buzhi smiled, "Qi Gongzi is not here, there are many contents in that book that the five princes can't understand, but they can't leave the things over there, so they sent me to ask, not to mention that I haven't taken care of this child's homework for a long time, so I'll take a look today." ”

"That's what happened." Xi Duyun smiled and said, "Did you bring the book?" ”

It just so happens that she also needs to use this book, and now it's really a godsend, it seems that this red envelope really won't give her something empty.

"Brought." Xu Buzhi took out a package wrapped in yellow cloth from his arms, which was flat and neat, and looked very cherished, and placed it in front of Xi Duyun.

Seeing that he cherished this book so much, Xi Duyun knew that he had the right person.

This book should be made worthwhile.

Xi Duyu sat down, looking very reserved.

Xi Duyun opened the book and looked at it carefully.

I didn't think I would use it before, so I didn't read it carefully, but just taught Qi Lichen some simple words, as well as font simplification rules.

Modern simplified characters are simplified from ancient fonts, and many people will recognize traditional characters when they look at simplified characters.

Sure enough, at the end of the page, there is a method for making a water wheel pump.

Xi Duyun immediately said, "Can you give me a closer look at this book?" ”

"Of course." Xu Buzhi was stunned for a moment before replying.

"It seems that the red envelope is not exactly chicken ribs for me." Xi Duyun smiled.

Xu didn't understand what she meant, Xi Duyun reacted at this time, and almost said that she had missed her mouth, so she smiled wryly and continued to look at the book.

"What do the five princes don't understand?" Xi Duyun hurriedly diverted the topic.

Xu didn't know that much, and turned over one of the sides, "What does cement mean?" ”

Xi Duyun looked carefully, there are many chemical names behind the cement, no wonder you can't understand it, this is a very hard material, used in construction, water conservancy, if it is used to build a river dam, it must be very strong.

"It's a mixture of lime and volcanic ash, it's very hard, it's a cementitious material, it can mix sand, it's resistant to fresh and salt water, and it's perfect for building river embankments." "But where is the ash?" ”

"Lime is easy to find." Xu Buzhi said thoughtfully, "This lime is also often used in construction, but I looked at the introduction behind the cement, and the hardness is extremely high, so I thought about asking what it means." ”

Xi Duyun was also quite distressed, he hadn't heard of a volcano in the vicinity, and there were no residents nearby of the active volcano that was afraid it would erupt.

"Xu Gongzi, don't worry, I'll find someone to inquire." Xi Duyun said.

Xu Zhizhi's face showed a little embarrassment, "What's so embarrassing?" ”

"This is also what should be done, not to mention how much of a great thing this is for the benefit of the country and the people, even if you teach my sister kindness, I have to pay it back." Xi Duyun said with a smile.

I don't know if it's hard to excuse myself, after all, this matter is not a personal favor, but a major matter about the people.

Leaving Xu didn't know how to eat, and sending him out after eating, Xi Duyu was still a little reluctant, and she had always been shy, she actually took the initiative to ask: "When will Mr. Xu come next, I have learned all the homework given to me before." ”

Xi Duyun rubbed Xi Duyu's head and patiently explained, "Mr. Xu has something very important you want to do, and I'll teach you when I'm done, okay?" ”

Xi Duyu was also sensible, nodded, and didn't ask any more, Xu Buzhi smiled, and after saying goodbye, he explained some of Xi Duyu's homework before leaving.
