The ancients had a very strange theory, that is, less labor is a kind of happiness, and the monarch wastes people's labor, which is a great sin.

This set of theories has continued to modern society in the Three Kingdoms of Argentina, and the hard-working Chinese people can't understand why they choose to take a day of work and sleep when they earn enough money for a day's food, but Sun Xiangfu now understands, maybe it was the ancients of China who brought them badly!

Li Shimin criticized Sun Xiangfu's idea of breeding two crops a year in advance as useless, saying that it was a useless move to waste people's power to please the rich, and in his opinion, it was better to have the energy to get these crops, it was better to reclaim a few more acres of wasteland, so Sun Xiangfu's reward was gone.

At present, Sun Xiangfu cannot tell him in a language that Li Shimin understands that the nutrients of the land have specific values, and without the equivalent fertility to improve the soil quality, the fields in Guanzhong will become more and more barren, and excessive reclamation will lead to serious soil erosion, which will affect the ecological environment of the entire Guanzhong.

He was even more unable to reverse Li Shimin's and all the ancients' idea that more land is more wealth, so the first half of this performance was successful, because breeding had visible benefits, but the second half failed, because Li Shimin felt that it was completely possible to use the work of seedling cultivation to reclaim wasteland, and the reclaimed fields were fixed assets that could be passed down from generation to generation.

Therefore, Xingfu Village can be used as a breeding base to provide seedlings for the chicken farms, pig farms, and fishery farms that the royal family will soon open, but the fields of the royal farm will still be cultivated as before, and at most part of the land will be taken out to grow fish grasses such as golden cauliflower.

Fortunately, there are still some people who trust Sun Xiangfu more, such as Qin Qiong, he decided to let the villagers of Shiyi go to Xingfu Village to learn breeding after the beginning of spring, and plant the crops that Sun Xiangfu made up, in addition, there is also the Yu family, under the strong persuasion of Yu Xiuer, it was decided to hand over the family's 10,000 acres of land to Sun Xiangfu for management, so add burying, and Sun Xiangfu can plant nearly 100,000 acres of fields after the beginning of spring.

Qin Qiong accounts for the majority of this, his 800 households have more than 60,000 acres of Yongye land, plus his own general Zuowei's professional field is also more than 10,000 acres, Sun Xiangfu and his family are only 7,000 acres, plus the Yu family's 10,000 acres, less than a quarter of Qin Qiong.

"Well, 100,000 acres, it's almost enough to meet the demand."

Sun Xiangfu finished the statistics in the study, and breathed a sigh of relief, since he couldn't let the royal farm play an exemplary role, then retreat to the next best thing and use his own field to make an example for everyone.

"Why is my husband so keen on farming?"

Yu Xiu'er has been sitting at home for the past few days to sort out the script, compiling the plot behind, watching Sun Xiangfu open his mouth and close his mouth, and asked with some curiosity.

"To put it bluntly, our Datang is a farming-based society, as long as there is more output in the fields, and the people have food to eat and clothes to wear, the world will be peaceful and peaceful, and the people will be safe, so that we can live comfortably, and everyone will have more leisure to come to see our artistic performances."

Sun Xiangfu can't say too deeply to Yu Xiu'er, people who are too advanced in thinking are often regarded as crazy, at present, he can only follow the previous rhythm, do what he can first, and wait for everyone to see the results, and then it is not too late to imitate them, just like the happy village that was born out of nowhere, now that there are results, who is not greedy to look at it.

After the snow melted, the weather was fine day by day, Sun Xiangfu lived a day of early and late return, went to the East Palace in the morning to teach the piano, and rode a horse in the afternoon to investigate the situation in various fields, what land is suitable for planting what crops, no one knows better than Sun Xiangfu, return to the house in the evening and rehearse for one or two hours of the program, go to bed before midnight, eight or nine days will pass in a blink of an eye, and the Shangyuan Festival is coming.

"Young master, there is news from the small courtyard that studies papermaking, saying that they have succeeded." Uncle De took the reins after Sun Xiangfu's horse entered the door.

"Take me to see it."

With that, Uncle De hurriedly handed over the reins to the horseman Liu San, and led Sun Xiangfu to an independent courtyard in the corner of the middle courtyard.

Before entering the courtyard gate, Sun Xiangfu saw a few iron pots with the bottom pierced, needless to say, this must have been burned through when boiling the pulp, and then, Sun Xiangfu saw the straw paper that was laid on the bamboo mat by the craftsmen to dry, the straw paper was light gray, much thinner than hemp paper, translucent, Sun Xiangfu gently picked up one with his hand, and soon, he saw the cracks on it.

"Village chief, although the paper has come out, it becomes brittle after drying, and it is easy to rot." Marin explained with some guilt.

"Well, you have already succeeded in making these papers with plants and trees, as for how to make it more practical, and then slowly adjust the raw materials, just explore, and give the people in the research and development team a reward of ten yuan each, and there will be another reward if there is a major breakthrough in the future."

Although Sun Xiangfu broke a piece of sun-dried paper, he was in a good mood, there is no process in this world that can't be smashed with money, just to see if this process is worth throwing money.

Knowing that his group was rewarded with ten yuan, the atmosphere in the small courtyard instantly became lively, and everyone racked their brains to think about how to solve the problem of paper softness, and Sun Xiangfu stopped bothering them.

Uncle De, take these sun-dried papers to the study, don't we want to make lamps on the Shangyuan Festival, this tissue paper can just be used. ”

After a while, Sun Xiangfu found Shi Dalang, and the two picked up the firewood knife and began to scorn.

"Village Chief, are you going to make lanterns?" Shi Dalang and Sun Xiangfu both have experience in splitting and making fish cages, and they are very skilled in splitting bamboo poles into thin strips.

"No, I'm going to make a flying lantern, so you have to split it more finely and thinner." Sun Xiangfu gave Shi Dalang a demonstration by himself.

"Flying lanterns, what is it?"

"Of course, it's a lamp flying in the sky, let's make a big one when the time comes, and then hang a string of small lights below, like a fire dragon, and put it in the air to attract people from Chang'an City."

What Sun Xiangfu has to do is Kong Ming lantern, of course, people like Shi Dalang who have never read anything naturally don't know about Kong Ming lantern, but I heard that the thing to be made is a magical thing flying in the sky, and the firewood knife in his hand is a little faster.

At dinnertime, more than a dozen cages made of fine bamboo strips were made, and the little ones who came over to see the excitement helped to paste the pieces of paper on the cage, except for the bottom, there was no air leakage at all, Sun Xiangfu also drew a smiling face with a brush on the pasted lantern, of course, the largest one was enough to stuff an adult into the big sky lantern with three big characters of Wangjianglou.

"I'll give you a question, the fire oil in the big sky lantern burns a pound of oil in a quarter of an hour, and in the small sky lantern, a pound of fire oil can burn for half an hour, and there is a big sky lantern and nine small sky lanterns, if you want the fire oil in the big and small sky lanterns to burn for two hours at the same time, how much oil do you need to put in each?"

It was a very simple arithmetic problem, so after a while, a child answered.

"Big brother, you need a total of 52 catties of oil, of which 16 catties are big and 9 small ones are 4 catties each."

Sun Xiangfu couldn't imagine that the fastest mental arithmetic was actually the little sister Sun Lili, so he asked the craftsmen to take the copper kettles of different sizes according to the number of oil, and fixed the copper kettle on the hoop made of bamboo strips, and finally took all the large and small sky lanterns to the cement open space in front of the most Wangjiang Tower, tied the big sky lantern with a rope, and strung the small sky lantern and the big sky lantern together, and lit them at the same time.

"Village Chief, can these lights really fly?"

The children looked at the flames rising from the spout of the copper kettle.

"Of course, as long as you don't make any mistakes when you paste paper." Sun Xiangfu controls the ropeway with the largest sky lantern attached.

"And what is the principle of this?" Sun Deshou learned more from Sun Xiangfu, and asked with a more modern word.

"This is the principle of hot air rising, just like the underground fireplace in our Wangjiang Tower, charcoal is burned from the ground, and the first to heat is the top floor." Sun Xiangfu explained.

"Oh, the hot air is rising, doesn't that mean that if we make this thing big enough, we can take people to heaven too?" Sun Deshou continued to ask.

"Theoretically, it's like this, but this thing has poor stability, it's too unsafe, it's better not to bring people, you see, just this one lamp, I have to control it with a rope." Sun Xiangfu calculated the amount of oil, but did not calculate the time difference of heat accumulation, now, the small sky lantern with less space and load flew up first, but the big sky lantern was swaying and had not yet rushed up.

"Wow, it's really flying."

The children applauded and cheered at the Kong Ming lantern that rose into the sky, and the employees of Wangjiang Tower also ran out to see the excitement.

"Quick, find some more ropes to pick it up, put the lights high, so that the people of Chang'an City can see that there is no curfew tomorrow night, and they will definitely come to see the sky lanterns."

The children's laughter made Sun Xiangfu feel good, tomorrow is the Shangyuan Festival, just to find fun for the children, but he didn't know that Li Chunfeng, who had watched Sun Xiangfu make sky lanterns from the sidelines, had been in a fugue for nine days at the moment.

People can go to the sky, what a great feat, if he can go to the sky to see it, he is willing to die, so when the lantern was placed several times higher than the wall of Chang'an City, Li Chun disappeared into the night without looking back, even if it was a curfew, he had to bring the news back to the Daomen and inform Yuan Tiangang.

After a while, the movement in the sky really attracted the attention of some people who had not slept in Chang'an City, and the guards on duty in the imperial city noticed the abnormality for the first time and reported it to Shangguan.

Fortunately, Li Chunfeng didn't bother with the curfew and rushed back, otherwise, Yuan Tiangang might have made some jokes.

"Your Majesty, if this lamp is used for military purposes and transmits news, it will be very promising."

After Yuan Tiangang and Li Chunfeng explained the matter of the sky lantern to Li Shimin, they were in charge of Dugu Moudao in charge of the palace guard.

"Not stop there, this thing can go to heaven, if it can communicate with heaven and earth, take things from heaven and ······"

Yuan Tiangang didn't continue, but Li Shimin narrowed his eyes, he indulged in alchemy and cultivation in his later years, and it was not for nothing that he sought the art of immortality, and if he got too close to the Taoist, he would be affected somewhat.

"Quickly order Sun Zhengming to present the method of production." Li Shimin gave Dugu an order, then retreated left and right, and discussed secretly with Yuan Tiangang alone in the city.
