The boat followed the current, slowly downstream, and the shore guards rode slowly along the shore. The Dongyang River flows out of Yushan and eventually joins Weishui.

Since ancient times, Chang'an City has the saying that eight waters surround Chang'an, which refer to the Wei River, Jing River, Feng River, Lihe River, Wei River, Hu River, Chan River, and Ba River. The remaining seven rivers eventually flow into the Wei River, which then flows into the Yellow River. The Dongyang River is a tributary of the Wei River, flowing through Lantian, Wannian, Sanyuan and other counties around Chang'an, and the surrounding farmland of these counties all rely on this river to provide water (this is otaku speculation, don't take it seriously after all, it's a novel, and otaku can't find a suitable map). The small boat that Li Kuan and the others were riding did not take much effort to leave the boundary of the peak of Yushan Mountain and entered the jurisdiction of Lantian County.

Speaking of this Lantian County, Li Kuan was a little embarrassed, because he would come here more than 1,400 years later to visit the historical sites of the Lantian people, but it was this simple trip that made him come to Datang from the 21st century, which was full of countless exhaust gases and countless mockery. At this time, the 'old place revisited' is really touching.

Slowly the surrounding area is no longer wasteland, farmland begins to appear, Guanzhong is the time when the farm is busy, the wheat is almost ready to be harvested, and a large area of wheat begins to turn golden. The old farmers in Guanzhong are all in the fields, looking at the golden yellow of the ground and laughing heartily, this is their harvest, it is the fruit of their labor. A piece of wheat hung heavily on the top of the wheat stalks, and the needle-like wheat mangs pointed straight to the blue sky, and the wheat stalks were straight and thick, like soldiers.

It's another bumper harvest year, and the people will be able to starve to death a few less this winter. Li Kuan thought silently in his heart, when he came to this world, what he saw was not the prosperous era of the Tang Dynasty, the world was just flat, leaving a mess in one place; Hundreds of people have been displaced. These are the most industrious and kind people in the world, they have nothing else to ask for in their lives, only to have food and clothing, as long as they are hungry and have food and clothing, they will work hard and complain, but this world can not even meet such requirements.

In the past two years, in the city of Chang'an, Li Kuan has seen Wuhou driving an ox cart in the morning every winter, pulling out the bones that had been frozen from one corner after another, and then burying them in a mass grave outside the city. This made him change the habit of eating leftovers, and for the sake of those who were buried under that desolate mass grave, he did not dare to have leftovers like before.

After seeing too much, Li Kuan couldn't help but wonder why the bag of rice seeds he gave Li Er hadn't been promoted? Could it be that for the sake of the so-called political achievements, he will not start to promote it until he ascends to the throne? What other auspicious name is involved? If this is the case, Li Er's heart will be a little hard.

Li Kuan didn't ask, because since the day he took out the rice seeds, he had no intention of interfering again, he was a layman, and he had never done it himself for a day except for seeing the villagers do it. Although he grew up in a single-parent family, he never worked in the fields, and the family's fields were handed over to his uncle's family to plant, and he could give enough rice for two mothers and children to eat every year.

The current was gentle, and there were golden wheat fields on both sides of the shore, and the guards on both sides had to ride their horses in shallow water, which would be detrimental to protection if they were far away. However, after the boat floated over a wheat field, the color on both sides turned green, and Li Kuan stood at the bow of the boat, looking at the two sides of the river that had changed color, and was a little surprised.

The few little guys in the back didn't have these feelings, Xiao Nianwei was still on the edge of the boat, stretching out her little hands and not knowing whether she was playing in the water or teasing the little fish in the water; Li Lizhi has been taking care of her sister by her side, she is a competent sister; As for Li Tai, this fat man can sleep anywhere, so he is napping alone at the other end of the boat, that is, in the direction of the stern.

Li Kuan leaned the boat towards the shore, and only when he got close did he see what was planted on the ground, it turned out that this was already the territory of the eldest grandson's family, although it was not as vast as after Li Er ascended the throne, but there was also a large area, and the land was not planted with anything else, but Li Kuan's Zhancheng rice to Li Er.

Li Kuan got closer, only to find that this large area was full of rice, but why did he feel that something was wrong there? But he couldn't say it for a while, after all, he himself knew a little about these things, and he was not familiar with them.

"Second brother, why did you get the boat here?" Li Li questioned Li Kuan.

"Didn't I find the rice paddies here? Come and see if the seeds I gave to my father are valid, after all, they were given by the teacher. Li Kuan didn't hide these things, because Li Chengqian, Li Ke, and Li Tai all knew about it, so the secret couldn't be kept, one person knew the secret, and the two people knew the secret. If the three of them knew, it would be an open secret. The reason why Li Er indulged himself, the reason why the eldest grandson ignored it, and the reason why the eldest grandson Wuji was so jealous was because they knew about the so-called scientist.

"This is the rice seed you gave to your father, second brother? It's good-looking! But where does this rice come from? Why didn't you see it? Li Li asked.

"It's not time for the rice to sprout yet, and it's going to be a while, you see, the leaf in the middle that looks like it's wrapped in something, and that's the rice there." Li Kuan pointed to a rice plant and explained.

"How is this rice different from wheat! I can't tell where it's a plant, it's all grown into a piece! Li Lizhi wanted to distinguish how big a rice plant was, but found that this large area was all grown together, and it was impossible to distinguish at all.

"All grown together?" Li Kuan suddenly realized that rice is not like wheat, it grows straight, and the stem of rice is relatively soft, although rice and wheat have to be tillered, there is only one plant at the beginning, and it will become several plants when it grows, that is to say, a grain of rice or wheat seed will divide into many rice seedlings, wheat seedlings, and produce a lot of rice and wheat. However, the wheat stalks are stiff, the ears of wheat are straight upward, and the pollination is uniform, while the rice ears are too long and bent downward, once it is too dense, it will cause uneven pollination, and there will be a large number of empty husks, resulting in reduced yield.

"Who is this race? How do you grow like this? Will there be a harvest in this way? Even if you just throw seedlings around, it won't be like this! Li Kuan muttered in his mouth, it seems that this kind of old farmer who has been working on the land all his life can't handle this rice.

Li Kuan originally thought that Li Erzang was private, but he didn't expect this result, I am afraid that the rice seeds that Li Kuan gave Li Er have not harvested much in the past two years, maybe after leaving the seeds of the second year, the rest will be sent to the Qin Palace. In the past two years, Li Kuan once again ate the familiar rice, drank hot white rice porridge in the morning, and thought that rice could be sown in a large area, but he knew that this thing actually stumped the old farmers in Guanzhong.

I'm afraid that those old farmers who farm the land are still complaining in their hearts: these damn aristocrats, what kind of rice do they eat, not to mention wastewater, and the yield is still so low, it's just a toss!

Li Kuan called the guards on the shore and asked him to find the old farmer who was in charge of farming, but he planted the wrong thing, and the rice was not grown like this.

After a while, the guard came back with a large group of people, all of whom were tenant farmers of the eldest grandson's family, who had been busy harvesting wheat all this time, and all of them were working in this large field, when they suddenly heard that the little lady of the master's family had come, and brought the method of planting rice, and a large group of people came to watch.

A large group of people knelt down and saluted the four little children who had returned to the shore, Li Kuan looked at these yellow-faced and thin-skinned peasant men and women, and couldn't help but feel ashamed in his heart, especially the fat Li Tai standing next to him, this was simply a slap in the face, Li Kuan felt that his face was hot, this is the kindest person in the world, how could he suffer such a crime? And should I do something for them when I come to this era? Li Kuan asked himself this in his heart for the first time, but there was no answer, because he didn't understand anything, he was a junior high school graduate, and then he went to the city to work, he didn't learn any knowledge and skills, he couldn't do any handicrafts, he couldn't make paper and glass, although there was a system, but he didn't have the energy to exchange huàn things, fortunately, he still saw how others planted, and he didn't do it but he probably knew something.

"The old man is the steward sent here by the eldest grandson's family, and he has seen two little sons here, little county lords." An old man came out and bowed again.

"The old man doesn't have to be polite, how dare the kid be bowed by the elders!" Li Kuan was a little stunned by a large group of people before, but now where would he still receive the great gift of the old man who could already be his grandfather, and left his place with a stride.

"Listen to this guard master, the little boy knows how to grow this rice?" The old man asked Li Kuan.

"The kid does know a little bit about it, this kind of kid is given to the kid by the kid's teacher!" Li Kuan replied.

"It turns out that this Champa rice is the seed brought by the little boy, but I don't know how to plant it correctly? In the past two years, most of the shells that have been planted and recovered are empty, and there is not much to eat after screening. The old man complained in his heart, but he didn't dare to show the slightest leak on his face, for this rice, he was scolded a lot by the mother of the eldest grandson's family, that is, the wife of the eldest grandson Wuji. It can be harvested twice a year, but each time it is so little, one acre of land is far worse than growing wheat.

"It's all to blame for the boy not making it clear, this rice is going to be divided, that is to say, when planting seedlings, there must be a proper gap, otherwise they will all be crowded together, pollination will be uneven, and the yield will be reduced." Li Kuan said what he knew, anyway, it wasn't something profound, just pay attention to the gaps when planting seedlings.

The old man didn't understand what pollination was, he just knew that the rice should be planted at a distance, not densely packed together like now. However, the wheat planted in Guanzhong for hundreds of years has been directly sprinkled with seeds like this, and I have never heard of transplanting seedlings, so I asked: "How do you do this transplanting and pollination?" ”

Li Kuan was surprised, is it okay to do this? It seems that the agriculture of the Tang Dynasty is still very primitive and backward, no, it has always been like this, wheat is not as difficult to wait as rice, rice has to be soaked, and then the seeds begin to germinate fibrous roots and then raise seedlings, and then transplant seedlings, which is simply an irritating job. In the homeland of rice, Champong, the natives there use it in the same way as the Tang Dynasty, digging a pit with a stick in the ground, then throwing a few seeds into it, covering it with soil, and then waiting for the harvest. Such an extensive planting method is simply a savage behavior, and Li Kuan deeply despises it.
