People's hearts are profit-seeking, this is what Li Shimin does not want to see, there will be big problems in rushing for quick success and quick profit, the Sui Dynasty is so destroyed, Li Shimin saw this, so he was very worried.

Sometimes he would look at Sun Xiangfu with a complaining eye, because it was this kid who made the country more and more difficult to govern.

Sometimes, he is very grateful to Sun Xiangfu, without the many things he has done, there are so many smiling faces of the people in the Central Land.

The secret guard sent a message to him some time ago, saying that Happy Village was going to sow seeds in the second season of this year, and the surrounding people, including the tenants of the major magnates in Chang'an, all rushed to watch, with more than 10,000 people.

The presiding over the sowing was carried out by the Sun Dali brothers, who not only removed the guards, but also prepared thirst-quenching tea for the people who came to watch and learn the planting techniques, and those who did not bring dry food only needed to pay two cents to buy a bowl of rice porridge with meat foam in the public house of Xingfu Village to satisfy their hunger.

They did not hide these secret techniques of getting rich as treasures like other families, the young man named Sun Erli, and carefully explained the skills of planting melons to everyone, and when they came, they also took out the seeds of two new crops and distributed them to the people, telling them to take them back and plant them near the water source, it is said that these seeds can grow a kind of Chinese cabbage and cabbage with a yield of thousands of catties per mu, especially the Chinese cabbage, which is not afraid of frost and snow burial, and is the most crisp and sweet to eat in winter.

Not only that, due to the small drought in Guanzhong this year, many crops that need more water can not be planted, and the two brothers also called on farmers to pay attention to ditching and diverting water, and when there is a drought in the coming year, try to plant these drought-tolerant crops they planted this year.

Li Shimin is looking forward to seeing what can grow on the land that will be idle after the autumn harvest in Guanzhong every year, so he is more supportive of a series of actions in Happy Village.

Also a few days ago, more than a dozen counties in Guanzhong came over, saying that they didn't know how to collect taxes, because of the reservoir, each county has thousands to tens of thousands of acres of fields planted with golden cauliflower and other fish grasses, these grasses are different from grain, can be harvested almost every day, how can the imperial court collect taxes on this new crop? Every day they send people to guard their fields, see how much fish and grass they sell, and then thirty taxes one? Or do you count how much fish and grass they sell in a year, and on an annual basis, thirty taxes one? Either way, that approach isn't suitable.

In the end, after Li Shimin discussed with the ministers, he collected the tax according to the average grain tax collected by Zhongtian, and as a result, within three days, the counties reported that these farmers who planted fish and grass had already paid all the taxes for this year, and the copper coins of a water were settled on the spot, you know, this is just July, and there is still a month and a half before the autumn harvest! Where do these people get so much money?

Li Shimin sent secret guards to find out that these farmers who planted fish and grass sold fish and grass to various feed workshops every day, and each feed workshop settled with them in cash.

Even if 80 acres of land encounters a good harvest year with good grain prices, how much can the grain produced be sold? At most, it is only forty or fifty yuan, you know, it is only July, and those fish grass fields are said to be able to harvest fish grass for three or four months, that is, the farmers who have planted fish grass can earn more than 50 yuan this year.

A farmer with an annual income of 100 yuan?

Li Shimin didn't dare to think about it before, Sun Wuji, the head of the household department, had already regretted setting the tax low before him, if the farmers who farmed the fields could earn 100 yuan a year, the petty officials and those officials who did not enter the stream would probably rebel in the future.

However, Li Shimin finally rejected the request of the eldest grandson Wuji to reformulate the tax on these fish and grass fields, and hiding the wealth from the people was one of his governing ideas. Moreover, the secret guard told him that these people who planted fish grass were very hard, and every day the whole family had to go into battle to cut fish grass and send it to the workshop, and the amount of labor was several times that of ordinary farmers, and they also paid the same amount of sweat for such a high income.

Li Shimin doesn't like to take advantage of the common people, he only likes to take advantage of people like Sun Xiangfu who are too capable of making a fortune, just like the honest Wei Chigong, he doesn't have as many ways to make money as other powerful people, so Li Shimin's reward for him is the most generous, Qin Qiong has been very rich recently, even if he has the merit of sacrificing his armor, Li Shimin only praised a few words verbally.

Today, Li Shimin remembered this stubble, and the qi in his stomach was very uncomfortable, even if Sun Xiangfu was not in Chang'an, he still sent a message to Yu Xiu'er, no matter what, after the autumn harvest this year, the crops must be seen in the fields of the royal farm, otherwise, the family law serves, who calls Sun Xiangfu a retainer!

Yu Xiu'er wanted to laugh when he received this message, he knew that his husband's status in the emperor's heart was getting higher and higher, so he hurriedly went to Xingfu Village to ask Sun Erli to prepare.

Of course, Sun Xiangfu, who is in Lingnan, doesn't know these things, today is a big day for Xuanzang to go to sea, and Sun Xiangfu intends to come to the dock to see him off.

In order to ensure his safety, Sun Xiangfu lent him the Happiness to travel, then, in order to keep the Happiness safe, Sun Xiangfu had to let the escort accompany him, Xi Junmai took the initiative to ask to accompany the ship, after seeing the customs of Jiaozhi, he really wanted to see what kind of country Tianzhu was, anyway, the whole world could not satisfy his curiosity.

It is only three or four thousand kilometers around the left, with the speed of the happiness at sea, as long as there is no accident, it will be able to arrive in ten days, just after a round trip, the grain of Sun Xiangfu's experimental field has also been harvested, and everyone will return to Chang'an together.

"See you again, I don't know what year it is, master, have a good trip."

"Master Lao is sending you off, and the poor monk is gone."

The monk is so bland, he doesn't need any affectionate farewell words, and he doesn't need others to miss him, even the wealth brocade that Feng Ang gave him, he doesn't take a penny, a monk, if he goes to the Buddha country and can starve to death, it is a joke.

"This monk is wise, I hope he doesn't die at sea!"

"Don't worry, I have confidence in the Happiness, and there is no one on it who looks like a short-lived person."

Watching the Happiness leave Hong Kong from afar, Sun Xiangfu's breath in his heart did not relax, he only helped Xuanzang on his way to study.

This voyage is of great significance to him, if the Happiness can smoothly enter the Indian Ocean, then it will have the ability to sail from the Cape of Good Hope in Africa through more than 4,000 kilometers of sea to South America.

With hard basic conditions, the rest depends on luck, offshore navigation and far-sea navigation are two different things, the Cape of Good Hope area is adjacent to the westerly wind belt, the harsh meteorological environment and sea conditions make later generations call it the Cape of the Storm, Sun Xiangfu wants to let the ships of this period cross the Atlantic, luck is very important.

"I didn't expect that my heart would be empty after this monk left." Seeing the Happiness disappear from sight, Li Chunfeng's words disrupted Sun Xiangfu's thinking.

"Dao Chang won't be inseparable from the master during this time, and he has a relationship!"

"Bullshit, it's all monks, that feeling."

"I'm relieved when the Taoist chief says this, what, can I let go of the matter of the patient camp now? If you can, come to Baiyun Lake for a few days! There are just some things to discuss with the Taoist chief. ”

"What?"

"Academically, I would like to study an instrument that can locate at sea······

When he was in college, Sun Xiangfu once saw a sextant in the Science and Technology Museum, however, at that time, he only roughly swept the shape of the thing with his eyes, and only knew that it could locate the latitude and longitude where it was by observing the degree of the angle between the horizon and the celestial body.

There is a demand, there is an idea, there is a direction, then it is necessary to explore slowly, Li Chunfeng is a professional who sees the world in this era, Sun Xiangfu will naturally not be wrong to find him to study together, so, in the peninsula waiting for the rice to mature, in addition to eating and sleeping, they began to have a lot of academic discussions, many junior high school, high school learned mathematics, physics knowledge was also Sun Xiangfu to discuss with Li Chunfeng.

And for learning these unknown knowledge, Li Chunfeng's enthusiasm is obviously higher than Sun Xiangfu's imagination, however, the more you understand, the more doubts you have, when the model of the sextant was created by Sun Xiangfu according to the vague memory, Li Chunfeng and Sun Xiangfu did the experiment, the place they chose was on the sea, when two sets of test data and an example were placed in front of Li Chunfeng, he did not sleep for three days.

Because he found that this world may really be like Sun Xiangfu inadvertently said a sentence, it is a round ball, otherwise, why would he be the first to see the top of the island on the sea, the same is true for sailboats, the first thing to see is the mast, the most important thing is the angle, the sea level of Guangzhou and Yazhou is not at the same angle as the Big Dipper, and it is not at the same angle as the Ziwei Star that he doesn't know how many times he has seen it in a year.

"Is it really possible for our world to be round?"

"All I can say is that it's very possible."

Although Sun Xiangfu said so, in fact, he had asked the craftsman to plane a round ball with a planing iron, and began to draw a dotted line on it with a pen, and he still remembered the general shape of several major states in later generations.

When he wrote the entire sphere full of words, Li Chunfeng snatched the ball and carefully looked at all the numbers on the sphere.

"Yes, yes, only if it's a sphere, we can explain the change in this angle, but if it's a sphere, why doesn't the water flow low, people, how can they stand ······ steadily?"

Sun Xiangfu still remembered his stunned appearance when he first saw Li Chunfeng, patted him on the shoulder and said, "Dao Chief, please take a look." ”

After speaking, Sun Xiangfu threw a coconut in his hand into the air.

With a "poof", the coconut fell to the sea.

"Does the Taoist know why this coconut can't keep flying into the sky and falls?"

"Nonsense, because coconuts have weight!"

"Of course I know that coconuts have weight, but why do they have to fall to the ground instead of the sky?"

"Falling into the sky?"

"That's right!"

"This ······" Li Chunfeng's brain was asked by Sun Xiangfu to crash.

Afraid that something was wrong with him, Sun Xiangfu hurriedly said, "Perhaps, our earth has suction, and all the rivers and lakes that exist on the earth, or birds and beasts, are sucked on this ground by him, unless they can break free from its suction, otherwise, they will eventually stick to the ground." ”

Hearing Sun Xiangfu say this, Li Chunfeng became more and more ignorant of the world.
