Autumn is high and crisp, and there are no clouds. At this time, Qingji, accompanied by Fan Li, Bo Yan, Lu Ban, cadres and other ministers and guards, took a military car to inspect the edge of the field outside Xianyang City.

It was the autumn harvest season, and the farmers were in the fields with sickles in hand, cutting the corn. Rice, millet, millet, wheat, beans, these grains are the staple food of people, so whenever the harvest season comes, every household can always take out the surplus grain to worship the god of grains.

Several members of the family are busy. The adults are responsible for harvesting the ears of corn, and the children are patting the broken grains on the side, pat the ears of grain down, and after getting the bags of corn slowly, they put the bags of rice aside with a smile on their faces.

"The King."

"See the King!" After seeing Qingji's figure, Li Shu, who was still busy, quickly knelt down and bowed to Qingji.

"You don't have to pay attention to the widows, and go about your work."

"Thank you, King!" That being said, but with Qingji by their side, how could they not want to look up to Tianyan?

After a while, under the old locust tree, a large group of people were seated, surrounding Qingji in the middle. Qingji has always had the style of an ancient sage, approachable, whenever he goes out on patrol, he will always cordially greet Li Shu and observe the people's feelings, and this time is no exception.

"Old man, how is this year's harvest?"

"Thanks to the king's blessings, the heavens are beautiful, this year's harvest is very good, and under the payment of field rent and various taxes, the surplus grain and rice at home should not be less than 300 stones." The old man replied with a smile on his face.

It stands to reason that an adult's ration for a month is three stones, and a year is thirty-six stones. For a family of five, it's 180 stone a year.

However, the elderly, weak, women and children do not eat so much, so this data has to be greatly discounted.

"How many people are in your family?"

"Returning to the king, the grass people have an insider, a son, three grandsons, and a granddaughter." That's a family of seven.

According to the decree of the state of Wu, a man must start a family when he reaches the right age, and a woman must marry when he reaches the marriageable age, otherwise he will be fined.

Moreover, after a man gets married and starts a family, he generally does

"Separate households", leaving only one son to be responsible for supporting the elderly. Basically, now every family in Wu has many newborns.

For a family of seven, the annual grain harvest is 300 stones. I eat about 250 stone of grain a year.

It doesn't look like there's much left, and there's not much left! This made Qingji a little unexpected. After all, the Guanzhong Plain is so fertile, and it is a bumper harvest year, with abundant grains, how can there be only fifty stone of surplus grain left in a year?

Qingji frowned, and asked again, "Old man, how many acres of land does your family have?" ”

"Back to the king, the grass people's family has 202 acres of arable land." Two hundred and two acres of arable land is quite a lot.

Wu Guo's light tax on 15 taxes, plus the calculation of the endowment and the endowment, if the peasant family has 202 acres of land, it should not only produce so much grain.

"How much does an acre of land produce?"

"A good field can produce more than three stones, and an ordinary field can only produce more than one stone, less than two stones."

"Why? From the perspective of widows, Guanzhong is fertile for thousands of miles, and the land is very fertile. ”

"The king doesn't know. Although it is a bumper harvest year, the sky is beautiful, and there are several heavy rains this year, but sometimes there is little water in the farmland, and the canal irrigation is not in place. The old man sighed and said: "If this had been placed in the past, there might have been two villages fighting for the water source of irrigation farmland, but fortunately, Wu had strict laws and forbade private fighting, and the officials were wise and often urged farmers to repair canals and irrigate and properly distribute water sources." ”

"If not, the harvest may be a little less." Qingji, who learned about these circumstances, stood up again and looked around.

Is it a problem? You must know that the Guanzhong Plain has not been well developed at this time. In the past, when the Qin State was under the rule, most of Guanzhong was still pastures, with abundant water and grass, but there was not much arable land, and three-fifths of the cultivated land was not reclaimed.

Even if it is reclaimed, there is not enough water to irrigate, and the grain harvest is still poor. Zheng Guoqu!

Qingji remembered that great project in history. At that time, Korea was afraid of Qin, so it sent Zheng Guo, a hydraulic engineer, into Qin and offered suggestions to build canals, so as to consume Qin's manpower and resources and weaken Qin.

This move backfired and made the Qin state even stronger. Historical records: the canal is completed, the water of the silt is filled, the land of Ze is more than 40,000 hectares, and the harvest is one acre for a minute, so Guanzhong is a fertile field, there is no fierce year, Qin is rich and strong, and the princes are killed and said

"Zheng Guoqu" ......

"Bo, bring me the map."

"No!" Qingji took a sheepskin map, and then sat on the ground with his ministers.

"Second and third sons, the widow wants to build a large irrigation canal in Guanzhong."

"The west leads to Jing water and the east injects Luoshui, which is more than 300 miles long." Qingji told his thoughts to the ministers.

The Jing River rushes out of the mountains in the north of Chang'an County, flows to Liquan and enters the Guanzhong Plain. The plain is hundreds of miles from east to west and dozens of miles from north to south.

The topography of the plain is characterized by slightly higher in the northwest and slightly lower in the southeast. Wu Guo could make full use of this favorable terrain and start to build a trunk canal at the valley mouth in the northeast of Liquan County, so that the trunk canal would stretch eastward along the northern foot of the mountain, and naturally distribute the trunk canal in the highest area of the irrigation area.

In this way, not only the irrigation area is controlled to the greatest extent, but also a complete artesian irrigation system has been formed, which can irrigate more than 40,000 hectares......

"King Shengming!" The ministers all complimented.

"Luban."

"The minister is here!"

"I'll be solely responsible for the construction of this canal. 300,000 Kunlun slaves can be levied to dig the canal, and the repair matters can be done by the idle people, without thinking too much, and the manpower, material and financial resources can be satisfied one by one. ”

"No!" Lu Ban immediately agreed. It is conceivable that once this large-scale irrigation canal is completed, it will inevitably be a good thing for the present and for the future.

…… In the temple of Zide. At this time, Qingji was sitting on the throne and met one of his favorite sons, the son Wu Wei!

Gongzi Wei is a son born to Qingji and Mrs. Zhu Ji, the eighth son, a concubine, but quite talented.

Childe's talent is not in the military-political field, like the rest of the brothers, but in research and development.

Gongzi was worried about inheriting Qingji

"Love to invent" excellent genes, nature, has been following the Gan Jiang and other equipment masters to learn, and is good at adventure, love to travel the mountains and rivers.

This time, Gongzi Wei returned from various islands in Southeast Asia across the ocean.

"Son-in-law Wu Wei, see my father! Ten thousand years for my father! The prince bowed respectfully to Qingji.

"Wu Wei, don't be polite." Qingji walked off the stage, helped the son up, and said with a lot of emotion: "You are dark, and your body is a lot stronger, and you have suffered a lot outside in the past two years, right?" ”

"Hehe, father, it's impossible to suffer, anyway, it's impossible not to get tanned on the ship and on the island." Childe smiled wistfully.

"Have you seen your mother?"

"Not yet."

"Your mother misses you very much, remember to meet her later."

"No." Gongzi replied worriedly, and then said: "Father, this time the son returned from crossing the ocean and benefited a lot. Erchen captured more than 75,000 Kunlun slaves from various islands such as Wa Island, Malay Island, and Java Island. ”

"Okay."
