A few days after Zhang Mao left, Yumenguan was filled with joy.

The land yumingchuan wanted from Zhang Mao is located in Luqing's industrial development base, on both sides of the Beida River to the north of Jingtieshan.

Lu Qing once said that it is suitable for farming. If they can occupy that place, they can be self-sufficient.

So now the land belongs to them.

In Zhang's eyes, the wasteland is almost worthless except for herding horses and sheep. They don't know how rich the mineral resources in that area are, and they don't know that the land there can be cultivated in paddy fields and dry lands with a little transformation.

Yumingchuan didn't say much, but told Zhang Mao that even if they opened the business road, there would not be much tax. The money was not enough to support more than 1000 soldiers at Yumen pass.

The land in hecang city is limited. Seeing that the land on both sides of the North River is similar to that in hecang City, they want to farm there and solve the food problem in Yumen pass.

After thinking for a while, Zhang Mao agreed to yumingchuan's request and even mobilized Anxi's garrison to help reclaim wasteland.

Yumingchuan naturally rejected his kindness and said that there are more than 1000 people in Yumen pass. As long as there is no war, they can open up wasteland without occupying the garrison in Anxi.

Zhang Mao was naturally so happy that it was settled.

So when farming began in the spring, there were a full thousand soldiers at Yumenguan, all opening up wasteland on both sides of the Beida river.

First, he built a river embankment, built a canal with stones, and invited several craftsmen from Fulu county to make several waterwheel.

Looking at the blustery wind blowing in the Beida River, Lu Qing felt it a pity not to use it, so she asked those craftsmen to figure out how to transform this water truck that depends on the flow of water into a wind water truck.

In a few days, they really made it. They installed some "blades" on the wheels of the windmill. When the wind blew, they turned with the big wheels of the waterwheel, which was much more efficient than the original.

After that, they crushed the excavated phosphate rock and sprinkled it evenly on the field.

He planted spring wheat, cultivated paddy fields and beds, found a sunny and hidden place by the mountain, built several stone houses, left more than a dozen soldiers here to guard, and the rest returned to Yumen pass.

Lu Qing guarded her experimental field in Nanyuan lake every day and watched cucumbers and eggplants grow one by one.

Han Shuo often shakes his head to see Lu Qing. He usually finds her by the South Garden Lake.

Watch her tending plants he hasn't seen before.

"Brother, can you eat this?"

"Of course, you can eat everything in these fields. After you collect it, you can't live without your share." Lu Qing was very happy.

There are not only cucumbers and eggplants, but also sesame, broad beans, carrots, fennel and other spice seeds. They will never worry about food in the future.

Because the land here is fertilized, the rise is better than that in hecang city at the beginning. There is no comparison between these vegetables and spices, but wheat is too obvious.

When the wheat in hecang city just sprouted tender buds, the of Nanyuan lake began to wave dark green leaves and thrive.

Feng Yi's face is a little ugly. He has planted land all his life. He thinks he still knows a lot about land, but now he is compared by a teenager.

All the manure from the stables at Yumen pass has been pulled to hecang city. In this way, the crops there are still a little worse than those in Nanyuan lake. Are those stones really fertile?

Close to may, Feng Yi's old heart was completely dead, only because the wheat growth in Nanyuan lake far exceeded that in hecang city. Seeing the dark green color, he burst into tears.

"Han boy, where are you sacred? How do you know that those stones can help crops grow?"

"Oh, my master, he is an alchemist. He likes to carve these stones and other things. I know a lot from his experience, but many things are also guessed by the master. I prefer to try, ha ha..."

"I see. I'm an expert!"

Feng Yi believes it. He doesn't believe that a little boy will know this kind of thing. There must be immortals behind it.

Later, Feng Yi also asked for a lot of soil and chemical fertilizer and took it to hecang city to sprinkle it.

The fields on both sides of Beida River, whether wheat or rice, are growing better than Nanyuan lake, which makes Lu Qing smile and bloom. I always feel that yumingchuan is good for Zhang Maokeng.

Because at Lu Qing's suggestion, they also dug a cave in an extremely hidden place in Jingtieshan and moved the steelmaking workshop of Duwei mansion.

Local materials are used, and the production capacity is improved in an instant.

But this time they did not cast weapons, but cast a large number of farm tools.

They have reclaimed so many barren lands, and their ragged farm implements are not at all useful. They have been built up with new hoes and sickle and all kinds of shovel rake plough, and their efficiency has been improved.

At the same time, the petroleum brain was also moved out of Duwei's house, some in Beidahe and some in beacon.

The weather is getting hot, especially the sun in the northwest, which is very poisonous.

Lu Qing is getting more and more agitated.

After taking off her winter clothes, she wears less and less. However, her figure has changed greatly in the past six months. The original flat plate has long disappeared. Although it is not plump, there is always some meat before and after. If she wears less clothes, she will be seen to be different.

For example, the boy Wang Jian sometimes looks at her wrong.

It was a very tangled look, like amazing and disgusting, like disgust and like.

Lu Qing doesn't care about him. She is a God in the eyes of the auxiliary soldiers.

Everything that comes out of the big vegetable garden in Nanyuan lake is delicious. They have eaten peas, broad beans and cucumbers at the beginning of summer.

They have forged dozens of frying pans and built an oil workshop. All the beans that are usually fed to animals are sent to extract oil, and the remaining bean dregs will be eaten by them.

These oils are also used for cooking. They have never eaten such delicious dishes in their life.

It's not enough to just eat. The summer here is so hot that Lu Qing didn't think she had forgotten a very important thing until she wanted to eat a popsicle.

At that time, Lu Qing grabbed Yu Mingchuan and accompanied her to the area between Fulu county and Anxi County.

There is a large saltpeter mine in that area in later generations.

Saltpeter is very important to Lu Qing. No matter where she and yumingchuan can go in the future, saltpeter will be her last trump card.

Lu Qing just wants to eat a popsicle.

Under the poisonous sun, Lu was covered with history and her clothes were soaked. Finally, she found the saltpeter mine she wanted in the big Gobi.

Looking at those reddish brown ore lumps, Lu Qing almost wanted to cry.
