Hearing Jin Yu say this, the expressions of the three people in the room were all stunned, and then the older man spoke: "Baxian Bozhen is joking, isn't it a pity to feed pigs with such delicious things?" ”

"Huh. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info" Jin Yu was noncommittal, and asked: "It's rude under the bottom, I don't know what Shangguan is called?" ”

"Don't dare, the next official Guo Yu, the word is sincere, and he is the Shaoqing of Sinong Temple." Guo Yu hurriedly put down the boiled sweet potato in his hand sideways, and returned the salute. What was Li Chengqian's attitude just now, but he saw it in his eyes, he was an official from the fourth grade, but he didn't dare to take a stand in front of Jin Yu, and besides, the grade of the county uncle was two levels higher than himself

Jin Yu is very satisfied with Guo Yu's attitude. In fact, he was deliberately slow just now, looking at their attitude, cultivating and promoting sweet potatoes, he didn't want to interfere, but if the people who came to learn cooperated with him, he really didn't mind giving them this credit.

"This ''''''"

As soon as Jin Yu was about to give up, he saw the bearded man next to him get up dexterously, and bowed his hand and said: "The lower official Zhang Peng, the word Junjian, is the Shanglin Administration, and I hope that the county uncle will not be bothered by the lower officials, and he will not hesitate to give advice." ”

"It's easy to say, it's all about serving the country." Jin Yu looked like he had no shelf, and he could hear the meaning of others' words, this Guo Yu was the leader who came to gild and participated in the guidance, and this Zhang Peng was the one who really learned.

Guo Yu and Zhang Peng were stunned at first, and then didn't say anything, just smiled. Jin Yu didn't feel that what he said was inappropriate, but the people of the Tang Dynasty could feel it. Ordinary people, whether they are polite or express their hearts, will say "serve the court", who will say "serve the country"?

"It's so delicious, why don't you finish the sweet potato?" Li Chengqian saw that the three of them had finished introducing them, and Yang Yang said, "I wonder if there are many sweet potatoes left in Dr. Jin's hand?" After the queen mother went back, she was full of praise, and she wanted to bring some back and talk about filial piety. ”

"Yes, as long as His Highness can carry it." Jin Yu picked up the sweet potato and nibbled on it and said, he is used to being with Li Chengqian, although the title is quite respectful, but he said it very casually, and he didn't show any respect for the superiors.

Seeing the master and apprentice behaving like this, Guo Yu and Zhang Peng looked at each other, lowered their heads and gnawed, no matter what, His Royal Highness the Crown Prince said that it could not be wasted, even if the stomach was supported, it would be eaten

"I'm afraid I'm going to bother Dr. Jin every day these days, it seems that it's a holiday, and Lone can't let Dr. Jin rest." Li Chengqian muttered while eating.

"Cheng, you have to work when you come to me, don't be tired when the time comes." Although he was guarding the two subordinates, Jin Yu did not be polite to Li Chengqian. Jin Yu likes harmony in his bones, and he doesn't want to have that kind of flesh-and-blood situation again. There are some things that you still have to do if you can do your best.

"Loneliness is never too bitter to cry tired." Li Chengqian said. After Li Er gave the order, Li Chengqian was called over by Empress Changsun and secretly told Li Er's intentions. Of course Li Chengqian wants to be praised by Li Er, he has grown so big, except for when he was young, he was admitted by his father, how could he have it at other times? Li Chengqian wanted to get Li Er's affirmation through his own efforts

"That's fine. After eating for a while, I went around the melon field. Jin Yu finished eating the sweet potato in three or five bites, took a sip of shaved ice, and greeted: "The shaved ice I made myself is very good for relieving the heat, everyone come to a bowl." ”

Shaved ice, those orphans in Zhuang Xue all pushed the cart to Chang'an City after the holiday, and sold this thing, although it was not cheap, but it sold quickly. Guo Yu was fortunate enough to grab a bowl, which is definitely a good product to relieve the heat.

"Without further ado, how about going now?" Li Chengqian drank it in one gulp, chewed the ice ballast, and touched his mouth. His hearty posture made the two subordinates secretly surprised, is this still His Royal Highness the Crown Prince who always pays attention to his appearance? …,

Jin Yu looked at the sun, took four straw hats from the side, handed them to them and said, "The sun is too poisonous, I'm afraid you can't stand it, put on the hats, save your face and shed your skin." ”

Li Chengqian knew that this was an allusion to himself, and his skin and flesh were the most delicate, so he glanced at Jin Yu gratefully, and there was no ink in it, so he put it on and made a gesture of please.

For Jin Yu's carefulness, Empress Changsun has experienced it, so she is very relieved to throw Li Chengqian to the Jin family Zhuangzi, knowing that her son can't suffer a loss, but what should Changle '''''' do?

The sweet potato field is also not far from the bridge, and Jin Yu also considered choosing this place. This place is close to the main road, standing on the restaurant can be seen at a glance, can effectively prevent the occurrence of theft, the night patrol Zhuangzi people will not walk more to take care of, everything is from the perspective of "people-oriented", humane is very humane.

Pointing to a large area of sweet potato seedlings that were dying, Jin Yu told the three people present how to cut and how to manage them. To put it bluntly, there is really no big technical aspect of this work, and the only inconvenience is the inconvenience of using water for cuttings. There is no bucket in these years, if you use a wooden bucket, the water will be rattle, and you can't push it with a cart at all, and the two sides of the cart in this year are also made of rattan, and the bucket cannot be put unsteadily, so such a large piece of land is picked out by the farmers with their shoulders.

"Lord Guo, if Sinong Temple wants to keep some seeds, it is best to gather the land in the next few days, and then come over to cut some melon seedlings, and then miss the solar term after a while." Jin Yu took a long time, and did not forget what he promised to Empress Changsun at the beginning. Sweet potato is a crop, a piece of sweet potato can sprout 100 seedlings, such a large sweet potato field is more than enough for himself to plant next year, and the rest is good to sell the eldest grandson queen, Jin Yu doesn't mind.

"Baxian Bozhen is the pillar of the country, the lower officials will do it now" Guo Yu was stunned at first, he didn't expect Jin Yu to be so happy, and he was still thinking about how to speak, so he took the initiative to give it. Originally, he was going to confirm it, but when the words came to his lips and swallowed back, what if Jin Yu regretted it? It's better to get a good grasp of implementation.

"Cheng, come and cut it in the afternoon, and plant it before the sun sets." Jin Yu reminded again, this is not nonsense, if it is planted under the sun, under the exposure of the sun, the salutation rate is very low.

At any time, the efficiency of the state apparatus is high and scary, and the Tang Dynasty is no exception. Of course, that's an afterthought.

Guo Yu saw that Jin Yu no longer had the strength to be a professor, and shouted that Zhang Peng went back together, leaving the crown prince Li Chengqian alone. After the two left, Li Chengqian asked Jin Yu: "Dr. Jin, is this sweet potato really fed to pigs in your hometown?" ”

"Well, feed the pigs." Jin Yu smiled, looking very bad, "But it's a little disgusting?" ”

"It's not disgusting." Li Chengqian was a little embarrassed to admit that he was a pig, after all, Jin Yu also ate it, "I just think it's a pity, isn't it a waste to feed such a delicious thing to pigs?" ”

"Hehe, in our place, this sweet potato is disaster prepared, usually it is boiled or roasted, eaten fresh, of course, it can also be brewed, but more often it is cut into slices, dried, crushed and fed to pigs. This thing is not picky, the yield is large, but it is not hungry for people, so it is most suitable to feed pigs, pigs do not dislike it, and they grow fast. Jin Yu told Li Chengqian about the use of sweet potatoes again.

"And wine? What does it taste like? As soon as Li Chengqian heard that he could make wine, his stomach was a little itchy, and he asked with wide eyes.

"No, the things that are poor and hungry can't be put on the table." Jin Yu waved his hand and asked with a smile: "Should Your Highness be more concerned about how to raise pigs and chickens?" ”…,

"All of this is seen by Dr. Jin? Dr. Jin is simply like a god" Li Chengqian touched his head embarrassedly, looking like a child, and embarrassedly admitted, this is indeed one of the tasks assigned to him by Empress Eldest Sun.

In fact, it was not that Jin Yu was like a god, but that after Yang Ying excitedly told Jin Yu what she said to Empress Eldest Sun, Jin Yu figured it out by himself. Who is the eldest grandson? Will the words of the question be meaningless?

"It's really unrealistic to say that this method of raising pigs and chickens is promoted." Jin Yu and Li Chengqian walked under the shade of the tree, sat down a little carelessly, and continued to explain: "It is true that I raise a lot of chickens and pigs in this village, but it is just a trick. Now the pigs are fed mainly by distiller's grains, but how much distiller's grains can Chang'an City produce in a day? After all, the supply is limited, and other Zhuangzi still have to rely on pigweed. ”

"So you can't promote it?" Li Chengqian asked with a disappointed face.

"There is a village chief in my hometown who once said, 'If there are conditions, we must go up, if there are no conditions, we must create conditions to go up' The current situation is similar to the situation we had at that time, all that is missing is time. This sweet potato, I planted it to feed the pigs, not only the sweet potato can be used to feed the pigs, but the sweet potato seedlings can also be used as pig feed when ground up. Anyway, this thing doesn't occupy fertile land, it's purely used to increase income. Jin Yu analyzed the current situation to Li Chengqian, "Oh, by the way, if you want to develop a large number of aquaculture, you also need to plant a large number of soybeans and peanuts. Soybeans and peanuts can be used to extract oil for the people to eat, and the remaining residues are feed for pigs, which is not wasted at all. ”

"If you can occupy fertile land, won't the grain output be less?" Li Chengqian raised his own questions.

"Do you know why you say that the dealer can eat it? It's because there is no oil and water, and they can't bear the heavy labor of eating pasta alone, so they must eat more, if the living conditions change, there are vegetables, meat, oil and water, who will catch the pasta and gnaw it? Not only is the nutrition comprehensive, but it can also save food. Jin Yu took a small wooden stick and wrote and drew on the ground and explained it to Li Chengqian.

"If there is less land to grow food, how can we save food?" Li Chengqian was even more puzzled, and he didn't understand what Jin Yu said.
