The fifth year of Tang Wude, the first day of August, auspicious, everything is appropriate.

Li Gang took Xue Lang to the outside of Hanyuan Palace, and a small yellow door stepped forward: "But Li Shangshu and Xue Counselor?" ”

Li Gang responded: "It's the old man." ”

Xiao Huangmen said: "The saint has been summoned, please meet the two of you." Come with the slave and maid. ”

"Thank you, father-in-law."

Li Gang took Xue Lang and followed behind the little yellow door into the Hanyuan Palace——

Xue Lang followed behind Li Gang with his head down, three steps away from him, always paying attention to whether Li Gang stopped. When he stopped, he stopped. Just listen to Li Gangdao:

"Chen Li Gang has seen the saint, the saint Wan'an."

Immediately followed suit: "Weichen Xue Lang greets the saint, the saint Wan'an." ”

A middle-spirited man's voice said, "The Qing family is flat." Li Qing and sit down, it is Xue Lang who comes in with you? ”

Li Gang replied: "Exactly." ”

Xue Lang immediately said: "On the Holy Gift, Xue Lang, a micro-minister, traveled thousands of miles in the early spring of this year and returned to the Tang Dynasty. Xue Lang brought sweet potatoes and potatoes from a foreign country to the princess, the princess was wise, and Xue Lang was trusted, and he tried to plant them in the field of Weize Pass. Who knows that once the trial planting, the seeds sown, the plants are sprouted, the young shoots are all seedlings, take root and sprout, bear fruits, sweet potato yield per mu is more than 20 stones, and the yield of potatoes per mu is slightly more than that of sweet potatoes. With such a bumper harvest, the Tang Dynasty is a blessed land of feng shui, a true son of heaven, and a testament to God's favor. In this way, I have the wind and rain of the Tang Dynasty, and the products are all abundant! Good news appears in the world, get this auspicious, dare not to report the saint? Because the princess was in an important position, she didn't dare to leave without permission, so she ordered Xue Lang to lead a team into Beijing to report the good news to the saint! ”

"Good! Pingyang and my son have a heart, and both Pingyang and Xue Qing have merit! ”

Li Yuan's voice couldn't hide his excitement, and his tone was quite high. Xue Lang hurriedly said: "Weichen doesn't dare to take credit, this is the destiny of heaven in Tang, and the saint is also a sign of great blessing." ”

The crown prince immediately said loudly: "Blessed saint! ”

Seeing this, the ministers also congratulated: "Blessed saints! ”

"Okay, well, the Qing family is exempt. On the occasion of this event, Xue Lang, where are the sweet potatoes and potatoes? Present it to the public and let me watch it together and share the grand event. ”

Xue Lang said: "The convoy carrying sweet potatoes stopped outside the palace gate, and asked the saint to give an edict, and the soldiers carried it in." ”

Li Yuan bowed his head and ordered Xiao Huangmen to go out and summon him. In a short time, two sergeants carried a basket, basket after basket, and brought in the sweet potatoes one after the other—

Hanyuan Hall is the place where the great dynasty and important ceremonies are held, the place is quite wide, it is such a wide place, more than 20 stones of sweet potatoes, but also full of a large place in the hall.

Because of the lack of seeds, there is only one basket of potatoes, but he is as witty as Xue Lang, and he deliberately left a potato seedling, and the potatoes on the roots, regardless of size, have not been removed, and even the plant with rhizomes is packed in a wooden box, and it can be seen at a glance that this is the yield of a plant-

One is already so much if planted on an acre...... The yield is almost immediately apparent. Although it is slightly inferior to the sweet potatoes that are almost piled up in a mountain, it is not much worse.

Xue Lang said: "Sage, these are sweet potatoes, the number produced by one acre of land. Because of the lack of seeds, the potatoes were only planted with half a cent of land, and the income was more than 80 catties, and Wei Zeguan left 15 catties as seeds for the next year, and the rest are here, please take a look at the sage. ”

The footsteps sounded, and the sage Li Yuan came down directly from the throne, walked over quickly, first looked at the box containing potatoes in Xiao Huangmen's hand, and then looked at the sweet potatoes in the basket, regardless of the soil still stained on the sweet potatoes, and directly picked them up and watched.

At this time, Xue Lang relied on his height to see Li Yuan's appearance clearly. His Majesty Li Yuan is wearing the emperor's crown, a solemn body, like all middle-aged and elderly men nowadays, Li Yuan also has a beautiful hair, a dark beard, only the hair roots exposed under the crown can be seen gray and white, thick eyebrows and tiger eyes, dignified appearance, and his demeanor is not as imposing as Xue Lang imagined, but quite kind.

The ministers also gathered around. The crown prince Li Jiancheng, who was dressed in a crown robe, and Li Shimin, the king of Qin, who had served in the court, also surrounded them, and they all looked at the sweet potatoes surrounded in the middle with burning eyes-

Potato seeds are scarce, and there is definitely no hope for promotion this year, and there are so many sweet potatoes, maybe you can get some seeds. I don't know if the ministers are fighting this idea, someone asked out loud: "Xue Counselor, dare to ask this sweet potato, how many catties of land do you need to seed an acre of land?" ”

Xue Lang looked at the person who was questioning him and was wearing a vermilion purple dress and replied, "Your Excellency, sweet potatoes are different from potatoes. In the first year of planting, you need to use tubers to make seeds, an acre of land needs about 15 catties of sweet potatoes as seeds, and in the second year, you can cut strong and well-grown cane seedlings from the plants of the year to raise seeds, and there is no need for sweet potato tubers. Potatoes can only be grown with tuber seedlings. ”

Li Yuan asked: "Xue Qing, Pingyang Shangshu once said that sweet potatoes and potatoes are easy to preserve, and they can be stored in the cellar until the next year. Li Qing reported yesterday that Xue Qing knew that there was a way to keep sweet potatoes and potatoes for several years after processing, is it true? ”

Princess Pingyang's recital only focused on the discovery of high-yielding new crops and the yield of new crops, but the detailed information did not say. Li Gang came back yesterday and went into the palace overnight to report to the sage, and he didn't know how to report, but the sage asked questions, and Xue Lang answered truthfully!

So, Xue Lang said: "Sage, about this matter, Weichen has written a sparse play, and is about to present it to the sage, please take a look at the sage." Just ......"

"Just what?"

Xue Lang said embarrassedly: "Weichen is long in a foreign country, accustomed to writing in the vernacular, and is not proficient in the writing of the literary language of my dynasty...... Why don't you make a verbal report from Weichen? ”

"Hahaha!"

Li Yuan laughed, laughing so much that Xue Lang's face turned red, standing in the middle of a group of ancients, he felt like an illiterate person, ashamed to see people.

Li Yuan said: "The Qing family's growth environment is different from my Tang Dynasty, this is an extenuating thing, it doesn't matter, and I just present the sparse performance." ”

"Thank you for the sage's kindness, Wechen is ashamed."

Xue Lang took out the copy of the sparse music that had been written all day from the sleeve cage of the big sleeve, and wanted to hand it out but was a little weak-hearted, looking at Li Yuan, he was a little hesitant.

Li Yuan smiled and glanced at the little yellow door beside him, the little yellow door immediately understood and stretched out his hand to Xue Lang: "Xue Counselor, please give the sparse play to the slave maid, and the slave and maid will present it to the saint." ”

Well, there is no need to struggle, the shortcoming of not knowing classical Chinese will be exposed sooner or later, and early death will be superborn. Xue Lang comforted himself like this, handed the music to Xiao Huangmen, and stopped caring about it.

Li Yuan took the sparse music handed over by Xiaohuangmen, turned the first page and saw the explanation of the meaning of Xue Lang's punctuation, lightly "huh", after reading it, he handed this separate page of paper to the prince on the side, and continued to watch Xue Lang's sparse music.

Li Jiancheng took the paper handed over by the saint's father, and there was still some inexplicability, when he saw the content on it, he glanced at Xue Lang, and his eyes seemed to be a little regretful. Then he handed the paper to King Qin, who was obviously waiting to see it.

King Qin took a look, his eyes lit up, and he looked at it carefully, thoughtfully. A minister wearing a vermilion purple dress on the side said, "Can King Qin let the old minister take a look?" ”

Li Shimin came back to his senses and hurriedly handed over the paper: "Please take a look at the internal history order." ”

The paper was passed to Xiao Yu's hand, and a group of ministers immediately gathered around and watched together. Xue Lang wrote concisely and to the point, these ministers were all erudite people, so they naturally understood it at a glance, and saw the benefits at a glance.

Xiao Yu said: "This punctuation mark is quite wonderful, whether it is used for enlightenment or writing, it is much more convenient." However, it is quite expensive to engrave books, and it takes time to make use of this punctuation mark. ”

This is the words of the old Cheng Mou Guo. Xue Lang arched his hand in admiration and said: "The internal history makes Gao Jian. ”
