In mid-August, after going around the three counties at the eastern foot of Helan Mountain, Li Ling only felt that he had really gained knowledge.

The "mass production" campaign carried out by Heifu not only allowed 5,000 left-behind people to participate in the work, but also mobilized all the soldiers, and at the same time thought of many interesting ways to encourage the soldiers to open up the wasteland and cultivate the land.

He took the early spring of clearing the wasteland as a competition, let all the soldiers and civilians participate, and there was one of the most powerful soldiers, in the first wasteland opening competition, created a good result of 3 acres of wasteland in one day, and was personally received by Heifu, who gave him six jue wine.

Throughout the spring, more than 10,000 people in the whole army have opened up a total of 200,000 mu of land, plus 50,000 mu of wheat planted last year, and there is already a large area of considerable arable land! Just enough to distribute to 5,000 single people, half of this year's harvest will go to the people, and half to the army.

In addition to clearing the wasteland, he also had to take care of his side business, because there was a shortage of women in Saibei, and the soldiers' clothes were torn, so they had to sew and mend them by themselves, and because the supply of clothes in the mainland was not timely, they even had to learn to make simple shoes.

After hearing about it, Heifu also met with him, and wanted to make the baby a small official who was in charge of the clothes of the soldiers and the people.

Unexpectedly, Guan Ying blushed and said that since he was left in the side, he didn't want to do the same end job as his hometown, he wanted to make meritorious contributions! Guan Ying said that in the past year, he learned to ride a horse with Ohara Rongbing, and now his riding skills are already good, he would rather give up the land, hoping to be a rider!

The arrogance of this small merchant naturally caused the soldiers to laugh for a while, but when the black man saw that he was very serious, he gave the infant a chance to perform riding in public, and it was actually quite good, and he was able to stop the horse and shoot the bow and arrow on the spot. So Heifu regarded the infant irrigation as a typical example among the people, and asked him to keep the land and hire someone to cultivate it for him, while he himself went to the obstacle and started as an ordinary cavalry squire.

In addition to agriculture, there was also animal husbandry, and Heifu fulfilled his promise, and Ohara was one of the first immigrants to move here. In the middle of summer, they moved away from the crowded northern plains and set up pastures around the farming areas at the eastern foot of Helan Mountain to serve as a garrison.

The five divisions of Dayuan were placed in three counties and two obstacles, and the Rong women in their tribe have also become the most active targets of the local Tuntian soldiers and single people's husbands - most of them are a little repulsed by the white sheep and Lou Fu Hu women that the government will allocate next year.

In short, after more than half a year of hard work, the eastern foothills of Helan Mountain, which were originally deserted and full of wild wolves due to the Xiongnu's northern escape, have become abundant in autumn and herds of cattle and sheep. In addition to the fact that it is difficult to grow hemp in the north, and there is not enough wool to shear, and it still needs to rely on the interior, the whole army has achieved self-sufficiency in food.

On August 15, the Marquis of Tuntian in the three counties sent the booklet to Heifu, who showed it to Li Ling:

"In the summer, Sumai harvested 100,000 stones, and these days, 80,000 acres of public corn fields in three counties have harvested more than 300,000 stones!"

Li Ling couldn't help but be surprised: "There are so many! The yield per mu has caught up with Shuzhong! ”

Heifu was not surprised: "The Huns of Helan Mountain have been grazing here for several generations, and tens of thousands of cattle and sheep manure have made the land very fertile, and they have accumulated over time, and now they have been released in the intensive cultivation of the Qin people, so the yield per mu in the first year is comparable to that of Shuzhong!" ”

This bumper harvest made it not a problem for soldiers and people to eat next year, deducting army rations, war horse fodder, and storing at least 50,000 stone of grain for later use......

"In this way, with the grain transported from the mainland, it can accumulate to more than 100,000 stone ......."

This is not counting the wheat that will be planted soon, and Li Qi felt that the pressure on his shoulders was greatly reduced: "In this way, the new people who will move here next year will not have to worry about food for the time being before the summer harvest." ”

Even taking into account environmental protection and sustainable development, the eastern foothills of Helan Mountain are enough to feed more than 100,000 people, so Qin Shi Huang in Xianyang finalized the resettlement plan for the coming year as early as the beginning of the year: relocate 30,000 households of Qin people from Guanzhong to Henan and Beijiao, of which 20,000 will go to Jiuyuan and Shuofang. 10,000 households went to Helan and established Lilu Xiaoyi around the fortresses and fortresses in places with abundant water and grass.

But Heifu didn't feel easy, and under the strong advice of Gongzi Fusu, these immigrants were not forcibly relocated from Kanto, but recruited from Guanzhong. Each family was given 50 acres of land tax-free for three years, and the government was responsible for building houses, providing necessary agricultural tools, seeds, doctors, wizards, and so on in each settlement.

This means that after the autumn, Li Ling's main job is to continue to open up the wasteland with the army and civilians, at least to build 10,000 houses for the 10,000 immigrants, and when the spring begins, he will also open up 500,000 mu of land with the immigrants......

This is an extremely difficult task, and the colonization work of Helan Mountain has just begun.

"The road is long, and the road is long......"

After personally participating in the construction of the Helan colony, Heifu couldn't help but remember this sentence in his heart. The Qin Dynasty's first colony in Saibei was really like a newborn baby, extremely fragile, and it would take a decade or two to really grow up.

This is also the reason why he needs Li Ling.

Heifu asked Gongao to spread out a map of Helan's colony for Li Ling to see.

"Captain Nongdu, please look, this place is surrounded by sand on three sides."

Like later generations, the colony is bounded by the Mu Us Desert in the east, the Tengger Desert in the west, and the Ulan Buhe Desert in the north.

"The reason why it can be so fertile and not swallowed up by quicksand is that Helan Mountain blocks the dry and sandy north wind, and secondly, it relies on the big river to continuously bring water!"

The moist river makes the banks of the eastern foot of Helan full of greenery, forests, grasslands, and a lot of water.

"But even if there is such a big river, there are only hundreds of thousands of acres of fields that can be opened up along the river's water, and if you want more, you need to build canals manually......

"The ancients said that those who are good for the country must first eliminate the harm of floods and droughts. Those who govern the country well must pay attention to water conservancy, at this point, I don't understand at all, but the captain of Nongdu, can the water conservancy built by Li County in Shu back then also reproduce here? Let the wild land where the jackal howls and the fox live become the Central Plains! ”

Li Ling hurriedly said: "It took ten days for the subordinates, accompanied by the officials, from Fuping in the south to Hun Huai in the north, and found that the water flow of this big river is very large, but the water is gentle, winding and smooth, as long as it is like the big father governing the Min River, find a way to divert the flow slightly, you can divide several ditches and irrigate the acres, but this matter can not be done in a year and a half, and the current manpower is also insufficient, and you have to wait for the arrival of Xinmin before you can start." ”

"Indeed, this matter is not urgent."

Hefu sighed, there was a serious shortage of labor, this was a big problem, even if he had invited the inkman to build a lot of water-powered mills and water vertebrae here, it still couldn't make up for the vacancy.

He could only set a small goal for Li Ling: "I only hope that Nongduwei can open the first ditch within three years, and by then, Helan County will not only have to be self-sufficient, but also have a surplus of tens of thousands of stones, which can support tens of thousands of troops to fight in the fortress......"

The cavalry army went out to fight and completely strangled the Huns! This is the policy that Heifu has adhered to for most of the year, and for this reason, he has a defensive attitude and proposes to build the Great Wall to protect Shuofang and Helan, and Meng Tian of Tuntian has differences.

"Even if you want to repair it, you have to behead Mao Dun before you can do it!"

Heifu's attitude towards Maudun being killed and then hurrying is no longer a secret, but the reason for it is that he can't talk to anyone, everyone only thinks that Maudun is a ruthless wolf, but they don't think that he can raise any big waves in the future.

Even Li Xin, who fought side by side with Heifu, was very puzzled by Heifu's obsession, and after the Qin army established a post station in Juyanze, Li Xin preferred to agree to Meng Tian's plan to defend the north and attack the west. First paralyze the Yueshi, and wait until the Shangjia finds out the population of the Yueshi tribe on the way, and lobbied the Wusun in the west to submit to Qin, and send troops together, then they can send troops from Longxi and Helan to launch a war of annihilation against the Yue. Even if the king of the Yue clan is now afraid of the Qin Dynasty, and he is offering protons to pay tribute, and he is opening up the trade route, he can't avoid the fate of his demise - who let him block the emperor's way to the western prince's mother......

Heifu's fears were confirmed in late August, when Heifu was discussing with Li Ling the planning of the settlement and farming area for the coming year, when an urgent report from Qianghua, the marquis of Juyansai, made the Beidi county lieutenant frown deeply.

"The Huns have sent troops." Heifu stopped his deliberations and threw the news to the group.

"Huh?" Li Ling was a little surprised, didn't the Xiongnu just be hit hard? Is this going to war again?

Gong Ao, Gan Chong and others were gearing up: "The Huns really have no memory, so they almost wiped out the whole army, and they are going to die?" We're just waiting for them! “

"Don't be too happy."

Heifu shook his head and said helplessly:

"This is the news of spring and summer, and now it has only been known by Ju Yanji and spread to Helan, and the direction of the Xiongnu troops is not to the south, but to the north!"
