Returning to the mansion from the palace, Jiang Lin had already returned from his father-in-law's house, and the guards had already eaten the food, which was made by the people sent by Rugui, not only the guards, but also the thirty miscellaneous servants and honor guards.

"Big brother, is everything going well?"

When Jiang Lin saw Xue Lang coming back, he immediately greeted him and asked with concern.

Xue Lang nodded: "Everything went well, it's just that after eating the court food, the court had an urgent report and participated in a court meeting, so I only came back now." What do you think? What did your father-in-law say? ”

Jiang Lin said: "Uncle Yue said that the day after tomorrow, he has little affairs in the yamen, so he can take leave and return early." ”

Xue Lang nodded: "It's okay, then I'll visit the door the day after tomorrow." ”

Xue Lang entered the house to change out of his official robe, changed into regular clothes, and sat in the main hall with Jiang Lin, Xue Lang said: "Today, the imperial court received an urgent report, and the Turkic Jieli Khan led his troops into Yanmen Pass, disturbing the annexation of the state and the original state. The imperial court had decided to send troops, and the king of Qin was the head of the march to meet Jieli. Wei Ze Pass is in a dangerous place, but I am afraid that it will be difficult to have stability. I plan to teach the people of Beijing to grow sweet potatoes and potatoes as soon as possible, and then go back to Weize Pass. What about you? ”

Jiang Lin said angrily: "Naturally, where the eldest brother is, the younger brother is there." ”

Xue Lang said solemnly: "Ah Lin, if there is a war in Wei Ze Pass, I am afraid that it will not be an easy war, I am afraid that it will be a hard battle, Liu Heimin is possible, and it is also possible for the Turks, you are just newly married, and you are still the only seedling in the family, if you participate in the war, in case of ......"

Jiang Lin directly interrupted: "Please forgive the younger brother for being rude, does the eldest brother think that the younger brother is such an unfaithful and unrighteous person?" Wei Ze has something to do, how can the little brother stay out of it? Big brother doesn't need to say much! ”

Xue Lang thought about it, and he was right. Although Jiang Lin is his brother-in-law, he is also a person under Her Royal Highness the Princess, if he avoids it at this time, what is it like! So, Xue Lang said simply: "It's okay!" Then our brothers will work together to help Her Royal Highness the princess tide over the difficulties! ”

Jiang Lin smiled with satisfaction: "That's how it should be!" ”

After chatting for a while, Xiuniang cooked a bowl of noodles for Xue Lang and brought it to him, and after eating, Xue Lang turned out a pen and paper and began to make a flow chart for planting sweet potatoes and potatoes-

He was in a hurry to rush back to Weize Pass, and he really didn't want to wait, so he simply made it into an atlas, which was simple and easy to understand, and it was clear at a glance, and it felt better to understand than an oral narrative.

Immerse yourself in drawing until the light is on, and in order to protect your eyes, immediately stop drawing, wash and sleep-

Since traveling to ancient times, the living habits have been forced to be much better, and they have become more and more regular. Two meals a day are getting used to it, even if you are not used to it, when you are hungry, it is at night, you are too lazy to get up to eat, and you are too lazy to get used to it! Eating so little, I don't feel like I have to worry about getting lucky in middle age in the future.

After thinking about it for a while, I finally fell asleep. A good night's sleep, get up and continue to struggle sweet potatoes, potato process schematic diagram, this picture is not complicated, complex will not play the role of the schematic diagram, the reason why it is slow is to think about the content of the drawing, and strive to draw all aspects of things.

The painting was almost the same, and Xue Lang called Jiang Lin over and asked him to see if he could understand it. If Jiang Lin, who doesn't know how to farm at all, can understand it, the old crop of that kind of field can be understood if you want to see it.

"Big brother, little brother feels that after reading it, he already knows how to plant sweet potatoes and potatoes."

After reading it, Jiang Lin said so.

"But what don't you understand or don't understand?"

"Wait for the little brother to watch it again."

"Okay!"

The two brothers were studying, and Changjian came to report, saying that it was a visit from the Si Nong Zhu Tun Supervisor of Sinong Temple. Xue Lang asked Changjian to welcome the guests in, and sat in the main hall and waited.

Si Nong governs the millet of the world. In ancient times, it was the real fat shortage department. Even in the Tang Dynasty, which was quite politically clear, there were not many officials who fell because of corruption and bribery in the position of Si Nong. Si Nong Zhengqing is a little better at management, and the surplus money and grain are enough for the emperor to cover the palace. During the Gaozong Dynasty, the palace room of Luoyang, the eastern capital, was dilapidated and needed to be covered, and it was the money and grain saved by Si Nong Zhengqing.

Zhutun supervises the tuntian fields in the world, and also manages the income of seeds. Personally came to the door to invite Xue Lang to the warehouse of Sinong Temple to teach the officials to select sweet potato seeds, which can be regarded as sincere.

Although Xue Lang has the title of the county duke, he only hangs a loose official in the court, however, Tang Cheng has a system, which is only a fixed rank and grade, not a minister.

"Xia Guan has seen Xue Jungong, and Xue Jungong is polite."

"Zhutun Supervisor is exempt, please take a seat."

"Thank you. The lower officials came here to ask Xue Jungong to go over and teach our Nongmen's subordinates to choose sweet potato seeds, so please ask Xue Jungong to move. ”

The quasi-eunuch said respectfully and politely. Xue Lang nodded and said, "Yes, please wait a while, I can go out when I prepare." ”

"Whoa."

Zhutun Prison patiently waited for Xue Lang to tidy up his clothes-

You can't let Si Nong Temple Zhengqing come to invite someone, that is, Xue Lang is big, and he lost his manners. It is appropriate for the Zhutun prison to invite people.

Now the people who act as coachmen in the house are the guards who accompany Xue Lang to protect him. set up a carriage and went to Sinong Temple with the eunuchs-

The advantage of the mansion being close to the inner city gate is evident at this time, and it is convenient to go to the yamen, for Xue Lang, who doesn't like to ride in a carriage, this is really a benefit that is not good! Thanks to Comrade Saints!

"Xue Jun is courteous!"

As soon as Xue Lang got out of the carriage after entering the door, an old man with a gray beard came out to greet him, and the Zhutun supervisor hurriedly introduced: "Xue Jungong, this is our Nong Zhengqing Yang Zhengqing." ”

Xue Lang hugged his fists as a salute: "Yang Zhengqing is polite, I've been waiting for a long time, let's go in?" ”

"Great goodness. Xue Jun Gong, please! ”

Going in with Yang Zhengqing, the officials are quite busy, yes, it is autumn now, it is the autumn harvest season in various places, and the Sinong Temple, which is in charge of the world's agricultural affairs, is naturally very busy. It was said in "Tang Hui Yao" that there are tens of thousands of servants in the four departments of Taifu, Shaofu, Sinong, and Taifu.

Choosing seeds is a very simple matter, Xue Lang only said the main points, and these people who often deal with seeds have already mastered the main points, and they quickly began to pick them-

The potatoes were selected by Xue Lang, and they should be kept until next year's spring ploughing.

"Yang Zhengqing, I have something here, please take a look at it."

"Xue Jungong, what do you need Yang to discuss?"

Xue Lang took out the drawn flowchart and handed it to Yang Zhengqing. Yang Zhengqing took it, at first it was just a normal look, the more he looked at the expression, the more serious he became, and after reading it, there was a look of joy between his eyebrows, and he praised: "Xue Jungong is a great talent!" This picture is quite wonderful, just a few strokes, how to grow sweet potatoes, potatoes are clearly said, but also very simple and easy to understand, at a glance, even illiterate people, as long as you compare this picture, a little explanation, you can understand. ”

"Yang Zhengqing won the award, all in order to be able to rush back to Weize Pass as soon as possible. In the past few days, I have been tired of Yang Zhengqing urging me a lot to end the sweet potato matter as soon as possible, and I will return to Weize Pass as soon as possible. ”

"Yes! Xue Jun is loyal and righteous, and Yang is not a person without adult beauty, so he will urge his subordinates to speed up. ”

Xue Lang hugged his fists and saluted Yang Zhengqing to express his gratitude.
