After all, Datang is a military empire, everything is military-oriented, although things such as quyuan plough and waterwheel are also valued, but for Datang, after all, they are not as important as horseshoe.

It's just that for Xu Hao, inventions like 10,000 horseshoes are not as important as things like Quyuan plows and waterwheels, after all, these things still have some merit, and military equipment such as horseshoes is completely absent.

So Xu Hao was depressed.

"I became an official not to be promoted and make a fortune, but for merit, but I haven't received merit for all these years, which is simply a waste of time."

Horseshoe, blast furnace and cement are all used in the military, naturally there is no merit, if it is not for the national fortune of the Tang Dynasty, Xu Hao may get a body of karma, and things such as quyuan plough and waterwheel for the benefit of the people, the merit is only one percent! In Xu Hao's opinion, he has basically worked for Li Shimin in vain in the past few years.

Wei Zheng smiled when he heard this: "The things you offer are all for military purposes, how can you have merit, if you can benefit all the people like Li Bing's digging of Dujiangyan and Zheng Guo's excavation of the Zhengguo Canal, the people will naturally be grateful to you, this is a thing that will last for centuries and have immeasurable merits." ”

"Water conservancy project, this is a matter of immeasurable merit, but the labor required for any water conservancy project will not be small, and it needs the full support of the imperial court, especially the support of His Majesty!" Xu Hao said.

Guanzhong area development millennium, water conservancy projects are also a lot, you must know that the first generation of the country of abundance said that the Guanzhong region, the Qin Dynasty built the Zhengguo Canal, the "Historical Records" recorded, the canal into the water, fill the silt water, irrigate more than 40,000 acres of brine land, harvest are all acres for a minute, so Guanzhong is fertile, no fierce year, Qin is rich and strong, unify the six countries.

It is said so elegantly, in fact, it is this Zheng Guoqu that makes the equivalent of 1 million acres of modern land become irrigated land, and the yield per mu has increased by three times, and because this Zhengguo Canal is an artesian canal, so the 1 million mu of land does not have to worry about drought, just relying on this 1 million mu of high-yield fields, the first emperor destroyed the six countries and ruled the world.

Don't think this is an exaggeration, in ancient times, except for a few lands along the river, there was little water to irrigate the land, and even the land along the river had to carry water, and Zhengguo Canal was an artesian canal, and even the steps of carrying water were reduced, which greatly reduced the consumption of labor, plus there was no drought to reduce production, it can be said that such a treasure land, than the output of 10 million acres of land in other places is higher.

In the Han Dynasty, among the strong cadres and weak branches, the farmland water conservancy in the Guanzhong area has been comprehensively developed, with a large scale and high efficiency, ranking first in the country.

At that time, the Jing, Wei, Luo and other water systems were developed, and large-scale water conservancy projects such as Longshou Canal, Bai Canal, and Liupu Canal were built one after another, which solved the problems of drought and soil salinization in the agricultural development of Guanzhong, and greatly promoted the development of agriculture in Guanzhong.

And now in the Tang Dynasty, because the world has been in turmoil for hundreds of years, water conservancy facilities have been abandoned a lot, and Li Shimin is a war maniac, and he has to fight a war every few years, so he naturally has no financial resources to build water conservancy facilities.

Wei Zheng had the intention of reducing the frequency of the Tang Dynasty and consolidating Guanzhong, the heart of the imperial court, and had long planned to build water conservancy facilities, but he had never found a talent for water conservancy facilities, and Xu Hao was proficient in hundreds of crafts, so he would give him a surprise when he thought about it, so he would ask like this.

And now Xu Hao's answer surprised Wei Zheng: "Xu Hao, do you really understand water conservancy?" ”

Xu Hao said: "I know a little, but I haven't practiced it!" But I can get a small water facility! ”

Xu Hao was also a child in the countryside when he was a child, and he also saw the water canals and hydropower stations in the countryside, especially when the water was released, the small canals in the countryside were all filled with water, and the rice fields were like mirrors, and the water was not rippling, which made Xu Hao remember deeply.

And now it doesn't seem to be much difficult to transplant to Datang, the hydropower station can be used as a water wheel, the canal has soil cement, and even Xu Hao can also make an elevated canal, and a water pressure to supplement, in this era, as long as the dry land is watered, the yield per mu can be increased by at least two to three times!

Then Xu Hao thought of struvite stone, soil fertilizer, and even his own soil fertilizer factory, this set of up to increase his yield per mu by five or six times is not a problem, this is really not Xu Hao's exaggeration, the Tang Dynasty of Journey to the West is still a feudal society, except for some more immortals, there is not much change at all, the yield per mu will not be much higher than the historical Datang, Xu Hao's promotion looks exaggerated, but compared with the current yield of less than 100 catties per mu, it will not feel exaggerated.

Thinking of this, Xu Hao found that farming is a good way to accumulate merit, first you can build water conservancy facilities in Guanzhong, and then the Central Plains, Hebei, Henan, Jiangnan, Liangguang, and even the world outside the Tang Dynasty, this world is not much different from the primitive society for Xu Hao, everywhere is a place where he has made contributions, especially he does not lack knowledge in this area.

Thinking of this, Xu Hao said to Wei Zheng excitedly: "The junior brother wants to become the order of a county, build water conservancy facilities in this county, and use his own ideas!" ”

Wei Zheng said with a smile: "With Brother Xu's merits, becoming a county commander is just a trivial matter!" ”

Not long after, under the recommendation of Wei Zheng, Xu Hao became the county magistrate of Lantian County!

And the first thing Xu Hao did when he became the county commander was to go all over Lantian County, explore the surrounding landforms and water potentials, and create a sand table in proportion to intuitively understand the entire Lantian County.

Then I found the squires of the whole county and told them the idea of building water conservancy facilities, which was good for them, and everyone agreed, but there was a bit of controversy about how much money to pay.

But money is a fart for Xu Hao, a traverser, he established a glass factory in Lantian County, although the manufacture of glass can not make a fortune, but Xu Hao is used to make glass greenhouses, not more than 100 acres, relying on Chang'an, a large market with a population of hundreds of thousands, soon the day into the gold, the start-up capital will be there.

As a result, the construction of water conservancy facilities in Lantian County was vigorously carried out under the leadership of Xu Hao.

It can be said that when Xu Hao occupied the sky, the Tang Dynasty had just ended the war, and the ambitious grass kings all died under the war, and most of the people who survived were honest and afraid of death, not to mention that Lantian County was close to Chang'an City, Li Shimin had already swept away the bandit and bully forces in Guanzhong several times, and even the noble forces were honest under Li Shimin's oppression, it can be said that the atmosphere of the founding period of the Tang Dynasty was the best, and it was also the most suitable period for doing things.

Therefore, Xu Hao does not have any lag in doing things, as long as he does things seriously.
