The first time he was summoned by someone at the peak of power, he was in a more apprehensive mood, before Sun Xiangfu had fantasized about the scene of his meeting with Li Shimin many times, but he didn't expect it to be in the harem, no way, he is now a retainer, nominally under the control of Empress Changsun, and it is not in accordance with the rules to go to the Taiji Hall or the imperial study to face the saint.

What did the Duke of Yi Guo say when he taught me to meet the emperor before? Forget it, just follow the TV series!

"Wechen see my emperor, long live my emperor, long live long live, see Niangniang, Niang Niang, Niang, Niang, Niang, Nian, Niang, T

Entering the Lizheng Palace, Sun Xiangfu saw Li Shimin dressed in a bright yellow robe on the Hu bed at a glance and the eldest grandson Wuwu dressed in a gorgeous long skirt, at this time in the Tang Dynasty, only the two of them dared to wear it like this, but when he shouted out for a thousand years old, the entire Lizheng Hall suddenly became quiet, the waiters, palace maids, and the eyes of the number one or twenty people were focused on him, and they didn't speak, they didn't move, just two words, embarrassed.

Film and television dramas kill people! Sun Xiangfu thought so, and continued to kneel on the ground and didn't dare to look up at people, mainly because he felt embarrassed.

"Well, today is not a sacrificial ceremony, there is no need to perform this prostration, you should get up first!" Li Shimin was pulled by the eldest grandson Wuwu's sleeves before he reacted and spoke.

"Thank you, Your Majesty."

Sun Xiangfu got up from the ground and stood firm, thinking about it, it is popular now to kneel and sit, if you kneel and bow, it is no different from sitting, at this time he remembered the bow bow taught by Qin Qiong, and a deep bow represents a big bow, but unfortunately it is too late, let others see his monkey ass face first!

Even if he didn't have much thought of superiority and inferiority, Sun Xiangfu knew that it was not right to look directly at the emperor, and Li Shimin looked at it for a moment before he heard the majestic voice again, "I heard that you have made a sharp tool for cultivating the fields, and the name is: Quyuan plow, why don't you dedicate it to the imperial court?" ”

Li Shimin couldn't be polite with him, a seven-rank petty official, and his words made Sun Xiangfu a little frightened, and after thinking about the wording, Sun Xiangfu replied, "Each other's ministers are just a farmer, they can't see the holy face, and they ······."

Speaking of this, Sun Xiangfu wanted to speak again and again.

"And what?"

"Moreover, someone once said to Wei Chen, if it weren't for Wei Chen's retainer this time, I am afraid that when he came to take office, he would capsize and drown on the Wei River."

Of course, Sun Xiangfu wanted to take this opportunity to give those families eye medicine, so that Li Shimin could value himself more, and as soon as he said this, Li Shimin's expression really became richer.

Li Shimin thinks and knows that the people who say this must be those sons of the family, this kind of farming weapon is of great use to the family that holds a lot of land in their hands, and the family is selfish, and will definitely take it for their own use at that time, so that their own family will benefit first.

"Hmph, these national tumors, sooner or later I will get rid of them."

Li Shimin snorted angrily, but was admonished by the eldest grandson, "Your Majesty, if you don't keep it secret, you will lose your minister." ”

Hearing this, Li Shimin's eyes glanced at the chamberlain and said, "Today's words, if half a word spreads, you and the other three clans will be wiped out." ”

"Wait and retreat!" After all, this is the harem, the territory of the eldest grandson queen, she ordered in a timely manner.

As soon as the servants came out, Li Shimin looked at Sun Xiangfu again, "What is the cement?" ”

Without the many onlookers, Sun Xiangfu's spirit was also loosened, and he arched his hand, "It's just that some stones are grinded, and then a little binder is added to burn something, and after grinding it into powder, add water to make it solidify again, which was accidentally discovered by Weichen when he burned lime in the countryside, and it is not worth mentioning." ”

"Really? That's not what the guards said, they said that when this thing solidifies in water, it can be compared to a solid stone, and if it is used to pour the city wall······"

"Your Majesty, it is true, but it is only a small piece, if it is poured as tall as a city wall, it must be interspersed with steel bars and stones, otherwise, once the cement is dry, it will be easy to crumble, or even collapse, and it is not as strong as the city wall made of blue bricks and clay."

"I see."

When Li Shimin heard this, he felt that this cement was a chicken rib, how valuable the iron of the Tang Dynasty was, as the emperor, he couldn't be clearer, quarrying, it was quite costly, if a large number of steel and stone were needed to build a city with cement, the court couldn't afford to play at all, not to mention, the burning of this thing first required a lot of manpower and fuel, which was simply worth the loss, but it made Li Shimin empty happy.

Of course, cement is not as useless as Li Shimin thought, it just appeared in an era that should not appear, if the national strength of the Tang Dynasty rises several times, the role of this thing will be great.

"Your Majesty, cement has some other auxiliary effects, such as a thin layer of brushing on the brick wall, which can make it smooth and beautiful, not eroded by rain, pouring a layer on the flat ground, as long as you don't take a heavy car, you can keep the ground flat and clean, and it can be used for repair and decoration."

Sun Xiangfu gave two examples to explain, after all, he is only using the soil method to fire cement, not as sharp as the best proportion of high-quality cement made on the industrial production line in later generations.

"Well, I know about this matter, after you go back, you will write a document on the method of firing and hand it over to the Ministry of Industry, in addition, the Quyuan plough will also be handed over to the general to be copied, and the method of production shall not be publicized to the outside world until I announce it to the public."

After saying this, Li Shimin was silent, Sun Xiangfu was stunned, this is the rhythm of sending off guests? Brother Ke gave the court a quyuan plow and cement! Shouldn't there be a lot of rewards, a viscount and a marquis or something?

"Wechen retired."

Sun Xiangfu bowed deeply with some disappointment, and was about to go home, but at this time, Empress Changsun seemed to remember something, and shouted at his back, "Wait." ”

was stopped, Sun Xiangfu's face was overjoyed, he immediately turned around and bowed down, and said in his heart, "I finally remembered the reward!" Don't worry, my brother will definitely postpone it again and again, and then accept it. ”

Who would have thought that Empress Changsun said, "This palace heard that you have built a huge barrage net in the Fisheries Division, which can catch thousands of catties of fish a day, but is there such a thing?" ”

"Uh, yes!"

After listening to the words of the eldest grandson, Sun Xiangfu was not good, and it was likely that there would be no reward, and he would be looted by others once.

"But the fish you send to the palace every day are only about 1,000 catties, and where are the rest of the fish?"

Sure enough, the iron rooster-like Empress Eldest Sun hit the Fisheries Division with the idea after discovering that eating more fish in the palace could save the use of other ingredients.

"Weichen asked people to use fishing nets to block out a piece of water in Niushou Pond and hoard it." Sun Xiangfu replied honestly.

"Well, it's done well, you don't have to hoard it in the future, let's send it to the palace!" Hearing this, Empress Eldest Sun nodded and said, after all, Sun Xiangfu didn't take it out and sell it, so he made extra money for himself.

"All sent to the palace?" Sun Xiangfu had a difficult face.

"Why, you don't want to?" Empress Eldest Sun stared at Sun Xiangfu s eyes, and a momentum that you don't want the old lady to clean up you released and said.

"Well, Weichen doesn't dare, it's just that the Inner Palace doesn't allocate funds to the Fisheries Division, and the Fisheries Division has more than 100 mouths and still has to eat!" Sun Xiangfu explained.

Those overcaught fish, but he is going to sell them and pay them to the subordinates of the Fisheries Department, and he will pay them all by the way, not only will he have to drink the northwest wind, but he will also have to pay his wages in vain, and the shops in the east and west markets will be in vain.

"So, you're going to sell the fish?" Li Shimin drank tea without interjecting, and Empress Changsun continued to ask.

"Yes, Weichen has set up two shops in the east and west markets in the name of the Fisheries Division, and plans to sell the fresh aquatic products caught more and earn some silver money for his subordinate officials, servants, and salaries." Sun Xiangfu explained honestly.

"The Fisheries Department is a royal yamen, how can you make a profit in business, but your actions are inappropriate."

Empress Changsun naturally also knows the truth that if you let the horse run, you have to let the horse eat grass, otherwise her drunken immortal building will not be so impressive, but it is the private property in her name, and it is different from the formal royal yamen such as the Fisheries Department of the Animal Husbandry Supervision Bureau, for a while, she can't turn around.

"Qi Yu Niangniang, Weichen believes that all the yamen of the Pastoral Supervision Office should find their own way to make profits for the royal family, so that the harem will not become a burden on the court and drag the country back.

At this time, the weather is cold, Chang'an fish is expensive, Weichen dares to assert that in the middle of winter, the price of fish will double and rise, at this time hoard fish goods, and then sell them in winter, which is a great benefit······"

"Sun Qing is reasonable."

Li Shimin felt his brain open when he heard the first sentence Sun Xiangfu said, in any dynasty, the use of the harem is the first major item of the imperial court's expenditure, if the Fisheries Division, the Forestry Division, the Animal Husbandry Division, the Agriculture Department and other institutions can make profits for the royal family, then the whole situation is different, and Sun Xiangfu is not just verbal, he has specific means of operation, he is a talent, so Li Shimin, who is extremely short of money, can't help but soar out of the word 'Qing'.
