Ye Hanji gave her the information handed over by the people below, and after searching for a while on the bookshelf, he found the records of the relevant dynasty.

Chu Yuxi unceremoniously took a piece of good rice paper and began to write and draw, first drew a ladder of general temperature changes, stopped halfway through the painting and looked back at Ye Hansi: "Do you have any information to add over there, this is not very comprehensive, only the information on the border with Dayuan." ”

"Exactly turned over." Yahanji handed over the book in his hand and watched her draw strange patterns, but her expression was serious and serious.

Holding a pen, comparing the sketches with the data and rigorously revising them back and forth, the bright eyes and bright teeth are tight and loose, and the serious appearance is Hua Ruo Tao Li, also known as Tao Xi Li Rang.

Ye Hanji looked stupid, with a straight nose and thin lips that were very sexy, looking at her, pious and affectionate.

With a bit of curiosity and inquiry, she always seems to know something that others don't know, and can always do things that others can't do.

That kind of whimsy didn't look like it could be raised in Chu Xiong's kind of waste mansion, let alone that waste might not even have been raised.

So where did she learn these things?

Chu Yuxi drew a rough sketch of the temperature and topography, carefully checked it again, and finally turned it over and redrew it again.

By the time all the transfers were finished, it was dark.

On the one hand, I lamented that the data at this time may not be accurate, or even laggy, and what can be relied on is the temperature and terrain.

The most infuriating thing is that there is no thermometer at this time, and it is impossible to say exactly how many degrees.

You can only guess the temperature and humidity based on the temperature you feel, the clothes you wear and the amount of water you need.

Not to mention the terrain, only human legs and horse-drawn carriages can measure the edges, roughly said to be mountains and rivers, and the distinctive topography of the 21st century is wishful thinking.

In such a vague situation, it took a whole afternoon to integrate the data before the drawing was completed.

I really have to thank myself for learning a little more geographical knowledge at that time, so from those messy temperature and topographic maps, it is not without reason to roughly speculate that the entire Yan Dynasty can be self-contained.

Along the national border of the Yan Dynasty, there is almost a complete circle of mountain ranges.

To put it more simply, the terrain of the Yan Dynasty is essentially a basin, and the special feature is that the terrain to the west of Dayuan is higher, and the side facing the sea to the east is much gentler.

This realization made Chu Yuxi a little relieved, at least this is the key to solving the situation of spring drought.

She drew pictures for a whole afternoon, and Ye Hanji watched quietly on the side for an afternoon, although she didn't know what she intended after watching for a long time, but she could roughly guess that it was related to the spring drought.

I didn't ask much, just waited for her to introduce it.

Sure enough, Chu Yuxi put down the pen and actively sour his hand, and introduced: "To put it simply, this is equivalent to the shape of a water basin, which I call a basin." Generally speaking, the edge of such a terrain will actually have a lot of mineral resources, and I don't know why the Yan Dynasty is an exception, in short, the terrain is relatively arid, and it is not very suitable for cultivation. ”

The conscious Ye Han Si's bony hand grabbed her white and slender hand, kneaded it and said, "You guessed it right, there are rich minerals there, and there are even very rare rubies. They don't know moderation, and more than 10 years ago, the immediate interests of the figure were excavated cleanly. ”

Greed and selfishness are human nature, and the degree of selfishness is inversely proportional to sustainability, and the more greedy you are, the faster the regime will fall.

No wonder the regime has fallen and fallen.

"That's it, it's okay, it's not important." Chu Yuxi pointed to the eastern coastal area and said, "The point I am talking about is actually in this area. ”

Looking along the place she pointed, Ye Hanji saw a small coastal hill, stretching for dozens of kilometers, almost encircling most of the coastal area of the Yan Dynasty.

But there's still nothing strange about it.

Chu Yuxi explained: "Most of the basins are dry because the wind speed is high in the flat area, which is easy to dry. But the general coastal, humid basin is the opposite, and can even be called the land of abundance. "Come on

The inference of the night Hanji is very smart: "You mean, this hill did not block the sea breeze, but it blocked the moisture of the sea, so the auspicious land became dry?" ”

Chu Yuxi, who was once again stunned by Ye Hansi's learning ability, was a little surprised, and then boasted with some pride: "Clever, so this long list of mountains is actually a failure." From there, we can turn dry land into a moist land, and one day it will become one of our main breadbaskets. ”

"Truth be told, this hill is man-made. I don't know how many generations ago, the king of the Yan Dynasty thought that the sea monster would encroach on their territory, so he ordered people to spend more than ten years to create a hill. ”

The sea is where the sea erodes the low horizon, but not too quickly.

What's more, the coastal area of the Yan Dynasty is actually not too low, and those problems can also be solved in the right way.

Chu Yuxi, who was speechless, was confused and incredulous by this, and said in a choked voice: "Talent." ”

Ye Hanji said lightly: "Not only that, but they also said that that the area was cursed by the sea monster, and if the sacrifice was not improper, they would be punished, so they regarded the droughts and natural disasters that have become more and more frequent in recent years as the punishment of the sea monster." ”

"Superstition is not shallow, it is obvious that they cut off the dragon vein, and they can still push the pot to the sea monster, which is also convincing." Chu Yuxi shook his head helplessly, and knocked on the table, very speechless.

Seeing that Chu Yuxi almost wrote "a group of fools" on his face, Ye Hansi, who had been superstitious for a long time, was silent, swallowed the words that the whole continent was superstitious, and put on an unfathomable appearance to make himself look less stupid.

Changing the subject, he said: "Do you want to demolish this place again?" ”

"That's too strenuous, just ask the Water Conservancy Bureau to go through the mountains and open up four reservoirs to divert water." Chu Yuxi pointed to four places from north to south.

First, to a certain extent, the water source is sufficient.

Second, bring a little moisture and moist moisture here, and raise it slowly.

In addition, the coastline here is still eroding the sand dunes, and drainage can reduce erosion, allow water to flow to the right place for people to use, and extend the life of the artificial coastline to a certain extent.

Let it truly become a project for the benefit of the people.

A hundred years later, this place will inevitably become a treasure of feng shui.

Looking at her expectant and yearning eyes, Ye Hanji rubbed her long hair: "Getting back to business, we don't think about things for so long, how can we quickly solve the drought in front of us?" ”

"It's still to divert water, but don't move the coastal side first, mainly let them use the water inside the Yan Dynasty during the persuasion period, so that we can be regarded as leaving a hole card." Chu Yuxi's coherent analysis.

Yahanji nodded, listening to her continue.

She picked up the pen and drew on the sketch as she scribbled: "But they still have problems, not only the problem of lack of water and drought, but also the problem of water and soil that cannot be conserved by lack of fertilizer. ”

"So the drought isn't over yet?"

"Yes, according to the different conditions in various places, it is recommended to pay attention to waterlogging, insect prevention, decay prevention, and late prevention, and the drought has passed and the waterlogging is not far away, so we must always pay attention to vigilance."

Chu Yuxi muttered to Ye Hansi again and tinkered with what he could remember for a long time, until his stomach growled, and then he found that the moonlight was hanging high.

Stretching his waist, he coquettishly said, "I'm hungry." ”

Ye Hanji pulled her to her feet and said jokingly: "Tell me how you know so many rare knowledge and strange theories, and the husband will give you delicious food." ”

Chu Yuxi, who stretched his waist and stiffened for a while, said haha: "Of course, this girl is smart and loves to read, and there are a lot of things left by the ancestors." ”

There was a moment of froze in the air.

But the night Hanji laughed and broke it, and took her to dinner.
