"Didn't we get a lot of cattle and sheep from the Turks, why is there still a shortage of ploughing cattle?" Li De asked curiously.

"Most of the Turkic cattle are used to pull fire, produce fur and make food, what we need is cattle, and they need to be domesticated for a long time." Li Xiuning explained.

"So that's the case, science and technology are the primary productive forces, and to increase production is to start with arable land, and I'll handle this matter."

Seeing that Li Xiuning lowered his head and got busy again, he went directly back to his study and began to draw a zigzag plow with pen and paper, this kind of farming tool, he didn't know much about it, he had seen it in the museum.

Whether it can be done or not, it is necessary for the craftsman to make it, if there are deficiencies and need to be improved, in fact, the composition principle of the curved plough is really not difficult.

Nowadays, the ploughs used by people are straight, and there is no mechanics at all to go straight and straight, which is not only difficult to pull, but also has broken courage.

It is completely applied by relying on the hardness of the iron plough [55 fo], which is definitely not able to pull for people, and it is also more difficult for cattle.

Li De was in the study, knowing that it was already a little dark at dusk, and then looked at the design drawings of various curved plows on the table.

In order to be on the safe side, he decided to have the craftsmen make a few more according to the drawings, and then practice to collect evidence, which one is better, in addition to the construction drawings of the new city wall.

Li De was drawn on a whim according to the appearance of a Western castle, and compared with the castle, the defensive power of the city wall is worth learning from.

Unlike the current Youzhou City, there are no other defensive measures except for the battlements of the city walls, at least it will be safer to add a moat, of course, the cost is high, and it is very troublesome to maintain.

Speaking of cost, the moat on his drawings was a widened pool, which was entirely used for fish farming, and if the enemy attacked him, the plan to raise fish would definitely be shattered.

He's just thinking.

"Boss, the dinner is ready, the ladies are already waiting." Luo Luo came over and said.

At the dinner party, there are only the ladies of the Li family in the back house, and there is one more Yujun lord, and it is still a habit of people in this era to share meals, especially those who are particular about doing things, and the more rules they have to do things.

Li De prefers to eat at a large table, how lively it is to get together, but sometimes the conditions are not allowed, where is the round table, and now the logistics support guards have no time to find craftsmen to build a table.

The dishes at the dinner were very rich, mainly barbecue, and a few stir-fried dishes, which the chefs of the Governor's Mansion had mastered very well, and they were well cooked.

"Husband, there's still a good show ahead." Pei Qingxuan said.

Not long waited, Luo Luo appeared in the hall with her singers and dancers, and began to perform after the salute.

The dances in the Western Regions are varied, and it is easier to understand them, and if you don't know Luo Luo's identity, it must be pleasing to the eye to look at the dance.

I can see that Matari and other female guards have changed into dancing girls, how awkward they look, there is a feeling of being targeted, and suddenly they turned their heads to look, and they saw where the girls on both sides were enjoying the song and dance, and they were clearly looking at him.

"Eat, I'm really hungry."

"What's the trouble?" Li De lowered his head to eat, pondering in his heart.

"Husband, Miss Luo Luo is following wholeheartedly, and the trip to the prosperous city is extremely dangerous, which can prove Miss Luo Luo's loyalty and courage, Luo Luo will live in the backyard from today, do you think it?" Pei Qingxuan asked.

Where is the inquiry, at a glance this expression is clearly that it has been decided, is his opposition valid?

"The affairs of the back house have always been decided by the ladies, and I approve of them."

Li De expressed his position and directly announced that he would not participate in this matter, for him, Luo Luo can also be a secretary by his side when he lives in the back house, there is no maid ring in the Governor's Mansion, and it is good to have more female guards.

After eating, Li De still had something to do, and in the dungeon of the Governor's Mansion, the prince of Jinlou was still a handsome boy in prison.

"Master Jin Lou, now that you are in Youzhou, don't hold on to the hope of being rescued, now you are not very popular in Fancheng, why bother to bury a good future for some secrets."

"I've already said that you can't get any information from me, don't waste your efforts, just kill me."

From the face of the golden building boy, Li De knew that if he continued to ask, the other party would not only not appreciate it, but would strengthen the idea of seeking death.

It's not to bring the golden mansion back to harm him.

"Why don't you tell me about the legend of the Moon Country, is it true that you are the prince of the Moon Kingdom?" Li De didn't ask for any more information, but took a stool outside the cage and chatted with the golden building boy.

There was a hint of hesitation when the prince of the golden building was silent, Li De saw clearly, maybe the legendary things may not be true, he is becoming more and more curious.

Seeing that the prince of the golden building didn't speak again, Li De continued to ask: "Does the Moon Kingdom exist, I heard that they believe in the god of the moon and worship the moon every night, if you tell me the truth, I may consider opening a framing window for you in the cell, and you can see the moon in the sky at night." ”

"The Moon Kingdom exists, and I am the Great Prince of the Moon Kingdom, and the legend is true."

Li De found a topic that could make the golden building boy speak, so he continued: "Are you willing to tell your story? ”

"There's really nothing in my story."

When the prince of Jin Lou said this, Li De thought that there was no follow-up, but the result was unexpected.

"The Moon Kingdom is an inconspicuous country among the countries of the Western Regions, and its only advantage is that it occupies a major transportation artery in the Western Regions and maintains its income by collecting tolls......"

Jin Lou Gongzi, formerly known as Jin Manyue, was coveted by many countries because of its geographical location in the key position of the Western Regions trade route when he was an adult.

The Turkic king at that time brought people to negotiate to make the Moon Kingdom their vassal, and the king of the Moon Kingdom at that time chose to fight the enemy, and it is not difficult to imagine how a small country could withstand 200,000 Turkic cavalry.

The king of the Moon Kingdom lost his life, and the queen left the Moon Kingdom with the remaining guards and people of the Moon Kingdom, and on the way to escape, the mother and son were captured by the Turkic cavalry.

In order to protect his mother, Jin Manyue exchanged the wealth collected by the king of the Moon Kingdom for security, and the person who told him the conditions at that time was the current general of Fancheng, Ashinagile.

Ashinagile is an ambitious man, after taking away the wealth of the Moon Kingdom, his strength has increased greatly, and various tribes have defected, and the golden full moon at that time is living in a compromised way, and being able to protect his mother is the most important thing in his heart.

The price to be paid is to use more money to meet Ashinagil's demands.

He is in trouble now, his mother is in the hands of Ashnagil, and he will not give any information, because everything he does is to protect his mother.
