In mid-February, Zhang De received a letter from Fu Qicheng, in which Jia, with the escort of Murong Nuo's bowl and the elite of the "Party Xiang Yicong", found three kinds of grass in a place called "Yak Sea".

One is clawgrass, Jia Shi sketched the sample, Zhang De judged that it should be something like Caspian clawgrass, in his previous life in the desert to see the scenery, next to the buttocks there is no less growth of this kind of potted plant on the petty bourgeois desk.

The second is ice grass, which can precipitate salt, and yaks eat ice grass, according to Jia's observation, the digestion is better, at least two percent stronger than ordinary pasture. However, the yield per mu is not high, about two stones per mu.

The third kind made Jia very excited, and specially sent a sample back, named "sand fixing grass", as the name suggests, this grass can fix sand.

In the letter, Jia described in detail the team's observations over the past two years, and said that a wubao could be set up near the "yak sea" to supplement yak breeding and grazing. At the same time, it is also possible to compare the sand fixing grass with the sample of Bolu Guo to see the solidification effect of the sand fixing grass on the desert.

This is not the first time that the characteristics of sand fixing grass have been discovered, and in the team with luggage Chunfeng, there are also Jia family elites. In the west of Bolu, the children of the Jia family also discovered the sand fixing grass, but no matter where the people were, they did not think of cultivating and planting the sand fixing grass.

But Jia is different, Mo Nan has carried out desert management, although the effect is almost invisible, but Jia Fei's experiment has been fruitful, but only Shicheng Iron and Steel Plant, Youzhou Firm, and Cangzhou City Bosi are not enough to support such large-scale experiments.

This time, Jia Shi was so happy because there was hope for a large-scale experiment.

“…… Zhang Gongrongyu, Cheng Duwei won four battles and four victories, captured cattle, sheep, horses and mules, and tens of thousands of Hu people. If you work with Hu people, you can fill grass blankets and plant sand grass in Guazhou, Yizhou, or Yumen. ”

The content of the letter is very simple, before the winter of Cheng Chubi last year, he attacked again, and the two big countries of Khotan and Shule must have been plundered by Cheng Chubi's elite soldiers. As for the reason, just look for one, the loss of a merchant, or the robbery of a caravan, are very valid reasons.

On the logistics line of the Western Army, there are many Chang'an noble white gloves, even if they are robbed once, it is an astonishing number. A smaller family can't say directly on the street. In recent years, there has been a trend of borrowing in Chang'an City, and there are more and more adventurers, but in the face of rich returns, no matter how stable the old farmers of Qinchuan are, they can't hold back.

No matter how wise the old and the elders are, they can't withstand the adventurous spirit of the younger ones. The vitality of young people lies in daring to fight, picking up a horizontal knife in their early years, leading a thin horse to be a fighter; It's not unacceptable to be a swordsman who travels west on an adventure now.

"It's getting more and more powerful."

Although I know that there is a reason for Cheng Chubi and Li Chunfeng to echo each other, most of the young generals who are outside may not be able to see the overall situation from such a high level. Cheng Chubi is not planning the gains and losses of a time and a place, and he will loot every winter, this is a water mill, and the Turks went south to rob differently, this is not a matter of survival, but Cheng Chubi has been thinking about destroying the country, pondering about the sacrifice......

Dunhuang is a very special place, the emperor has to build the Dunhuang Palace, this is the plan of the king, will not change. Because this is not only to preach political sovereignty, but also to be a military fortress, a bridgehead for the advance base, and a large rear for the expedition to the west. Therefore, when the emperor decided to build the Dunhuang Palace, the people also built a large number of horse farms, cattle and sheep farms, guest houses, Wubao, and even board rails in the Dunhuang area.

However, the original slab rails are rudimentary and can hardly withstand the baptism of nature for many years. It's not that businessmen don't understand this, but the maintenance cost and return are compared, or it is cost-effective to repair two.

Along the slab track, it is necessary to use Jia's sand fixation methods, and the biggest cost of the input is manpower. But it is precisely manpower that has become the biggest headache for businessmen. Dunhuang lacks people, a large number of people, and hundreds of thousands of people.

Originally, the best partner was Hou Junji, but Hou Junji was transferred back to the capital by the emperor to be the secretary of the ministry, and the matter was stranded for a while.

Zhang De thought about it, wrote the same letter to several important people in the "Zhongyi Society", and then ordered someone to send the letter out.

"What are you worried about?"

Cui Jue, who was proofreading, raised his head in front of the desk on the side of the screen and asked curiously.

"Well, the slave arrest the year before last caused a lot of turmoil. Now it's not easy to do things without looking for a reason. Let's take the name of 'merit in the present generation, benefit in the future' and deal with it. ”

"Are you arranging the scholars again?"

"I'm also a scholar, okay?"

Lao Zhang grinned at her, "Speaking of choreography, I heard that you like music, so I asked you, does this music have anything to do with arithmetic?" ”

"Why doesn't it matter?"

Cui Mingyue raised her eyebrows and looked at him with disdain, "You still studied under Lu Gong, didn't you learn to play the piano?" Lu Gong also gave you a handful of 'mountains and rivers on the surface', what's the matter, don't you just pluck it twice and get a 'two tigers' to coax the child. ”

You...... Know an egg!

"Don't say that there are some or not, someone in Chang'an in the first month of the New Year uses arithmetic to make a rhythm out, I really can't figure it out."

"What's wrong with that? Regardless of whether it is the law of three-point profit and loss or the three tones of the Southern Dynasties, it is today's ten pieces of music, all of which are set and then divided. If you can't do arithmetic, how can you become a family? ”

Speaking of this, Cui Mingyue was quite complacent, "I have also heard about the new music rhythm of Chang'an in the first month. It is a joint system of Dali Siqing and two girls, with Huang Zhong setting the standard, and the law system is equal to the opening. You are the one who makes the abacus, and you can't make the abacus? ”

What the hell am I ......

Sun Fujia, you are a legal worker, and you are not doing your job!

In the final analysis, the musical literacy of a certain engineering dog is really low, although it can be regarded as being able to stroke the piano, but it is basically at a level that the girl can't tease. Let him have an in-depth understanding of music theory, it is better to pick up a sycamore wood and go to the beads.

If you don't agree with the car beads or something, it is still very attractive to Jiangnan dogs, at least it is much more interesting than studying the proportional series, common ratio, resonance and so on in music.

"That's right, Aaron. Those two girls are said to be Wu women. Cui Mingyue's eyes were cunning, and she looked at Lao Zhang secretly.

However, Lao Zhang's body was shocked, and he didn't move, he was open!

It's not that Senior Brother Sun Fujia is not doing his job, but he happened to be involved in a case involving the "Famous Piano", and then Senior Brother Sun inadvertently went deeper, but the direction was crooked, he forgot about the case, and went into music theory. For this matter, I also went to find the "mathematical authority" of Chang'an City, one is Wu Shunniang, and the other is Wu Meiniang......
