Chen Xiucai also came, but he didn't come to plant trees, or to see the excitement.

Su Wu didn't drive these people who came to see the excitement to leave, and being interested means that they can develop into like-minded people.

Su Wu stood in the front row, pointed to the hay on the carriage and said, "After a while, everyone will look at it, and I will teach you how to make grass squares." ”

Northern Xia ran out of hot weapons, and the Qianqin State would not put Su Wu's "heavy weapon" into battle.

Of course, it was Su Wan who didn't let herself go into battle, Feng Jing didn't agree to take her to the battlefield anyway, the previous promises were all fooling her, what could she do if she was taken to the battlefield.

The battle is all about formation cooperation, Su Wu's fart doesn't understand, and fighting on the battlefield by brute force is also adding chaos.

Unless it's a 1v1 combat style, she really doesn't have much effect.

Therefore, Feng Jing 100,000 approved of her plan to plant trees.

Send it to the border city.

Although the nails on the Northern Xia side were all pulled out, because Su Wu went to the Northern Xia Royal City to do a wave of things, Northern Xia also changed.

The ministers, who were originally dissatisfied with Ye Siyin, an outsider, were blown up by the firearms she made and killed the Seven Princes, which caused huge public anger, and many ministers wrote to the Khan to deprive her of her status as a saint.

Ye Siyin was also unwilling to lose her status as a saint and was carried home as a concubine by the eldest prince in a small sedan chair, so Northern Xia was very lively during this time.

"30 is a lot, but this job can't be done for a long time, why waste time, maybe it won't be long to do, it won't be able to continue, it's better to be an apprentice to learn some crafts, and there will be a livelihood wherever you go in the future."

"What Uncle Zeng said is, what's the use of learning to plant trees, there is no owner in the northwest to recruit people to plant trees, and it is useless to learn to plant trees."

A literate old man raised his head from the recruitment list, "However, the meaning of this list is that planting trees can improve the sandy land, reduce soil erosion, and turn sand into soil in the future. ”

"Chen Xiucai, do you believe it? In the books of the sages you read, is there such a way to turn sand into soil? ”

In the face of everyone's inquiries, Chen Xiucai recalled very seriously, "No, but if it is not beneficial, why did this person spend money on us to plant trees?" Merchants can't afford to be early. ”

"Who knows."

A big man squeezed through the crowd of people watching the excitement, "If you don't want to go, forget it, I'm willing to go, I can do it as long as I can, this job is easy at a glance." ”

"Yes, anyway, it's impossible to plant live trees in the desert, we can deal with it casually, and when the tree doesn't grow, it's none of our business, hehe, Second Brother Qiao is smart!"

A group of people suddenly discovered the benefits and stepped forward to sign up.

Fei Jue, who was watching the excitement in the crowd, was very dissatisfied with this, these people really played stealing and playing tricks to the extreme, "Cousin, there is that thing, why do you want to find these people to plant trees?" ”

Isn't that a gift of silver for nothing?

Although he understands that the nutrient solution is still a growth fluid, and he can't just take it out and let people know, otherwise it will cause many countries to compete and cause wars, so his cousin will find someone to plant trees and hide people's eyes.

But it's just for show, there's really no need to cheapen outsiders, it's better to let those men in the barracks go and sow seeds when they are not fighting, and the fertilizer and water will not flow into the fields of outsiders.

Why bother to cheapen this group of sloppy and slippery lazy people.

In the base of the last days, there are many such people, but no matter how big the problem is, the captain has corrected it, and Su Wu is quite calm.

"For sustainability." It's important to pass on the technology.

Su Wan stepped forward, and the person in charge of recruitment saw her and gave way to her position.

Su Wan glanced at it a few times, although she didn't necessarily know all the names, she still knew how to count the number of people, flipped through the paper, and more than a dozen people signed up.

This efficiency is really not high, and her project is not favored.

But she didn't want to shout, so take her time.

"Ma'am?"

"It's okay, you continue to recruit people, just bring them over on time the day after tomorrow." Su Wan put down the booklet and was about to leave, but those people saw that the recruiter was respectful to her, so they asked.

"Madame, why are you planting trees here in our border city?"

Chen Xiucai felt that he was offended, he was a scholar, and he never spoke, "You juniors, if you don't study, you listen to the old man's words, what I say is written in the book of the sage, and it is recorded in the book that a thousand years ago, the border city was full of yellow flowers in spring, green water in summer, maple forests in autumn, orange and orange green, colorful fallen leaves, and rolling wheat waves, what a pleasant scene." ”

"But in the future, somehow, it became like this, the fertile land turned into sand, there was no way to grow melons and fruits, and the river was gone, hey......"

There were also people in the crowd who had studied, and after Chen Xiucai finished speaking, they supported on the side, "What Chen Xiucai said is that it is indeed said in the book, and it can also be seen on the picture scroll." ”

A businessman dressed as a humane, "I have been to the Northern Xia, and in the caves in the Northern Xia, there are murals from a thousand years ago, and there are also pictures of trees on them, and there are pictures of women giggling in the flowers, which are further northwest than ours, and they have trees over there, and we must have trees here a thousand years ago." ”

The big guy wondered, "Why is it sand now?" ”

"The soil of that place in the Central Plains is still fertile and the scenery is still the same after thousands of years, why has our northwest become like this?"

"Could it be that the Northwest is cursed?"

Su Wan guided and said, "Didn't you notice that the desert has been advancing towards the border city? In the past, there were still green plants in the border city, but in recent years, these plants have gradually decreased, and the wasteland outside has gradually become a desert? In the last two years, have the windy and sandy weather become more and more frequent, and the sandstorms are getting bigger and bigger? ”

"yes, it seems to be." "When I went to Bac Ninh, I could see green plants and soil for half a day, but in the past two years, I had to walk for a day to see green patches, and the sand seemed to have been advancing in the direction of the Central Plains." ”

"What's the reason for that?"

Could it be the heavenly punishment caused by the emperor's unkindness of ......? No one dared to say this.

Su Wan, a scumbag, doesn't know how to explain it specifically, she really doesn't learn geography well, but she still knows at least a little better than the ancients, and tries to talk nonsense, "This is after the Western Zhou Dynasty, the order to prohibit logging has not been obeyed by the country in future generations, coupled with frequent wars, the border burns trees and villages at every turn, or cuts down and sells trees to the Central Plains, and so on, causing fewer and fewer trees here." ”

"Without trees, would it be like this? Will the soil turn into sand? "There was a look of disbelief on everyone's face.
