Hua'an returned to the camp of the Northern Expeditionary Army to train day and night, especially the training of recruits was the top priority, a few months later, the recruits began to have combat effectiveness, and after a drill, Hua'an was quite satisfied.

At this time, it was the season of spring ploughing, and Hua'an felt that the daily cost of military rations for the 30,000 army was quite large, which added a lot of burden to the imperial court, so he went to the imperial court and asked Tuntian to raise troops to reduce the pressure on the treasury.

The imperial court was naturally very happy with Hua'an's request, but the fertile fields around the capital were occupied by the princes and nobles, and where to find a piece of land for Hua'an to use for tuntian became the top priority of the court officials.

If you ask for some fields from the hands of those princes and nobles to distribute to the Northern Expeditionary Army, it can solve the urgent need, but these princes and nobles will definitely not agree, the land is their lifeblood, so they will not give it to the Northern Expeditionary Army casually?

In the Eastern Jin Dynasty, when the imperial power was constrained by the scholars, as long as these land-owning nobles did not let go, even the emperor did not have a good way.

However, Hua'an had already learned about these situations before the performance, and he knew everything about the ownership of the fertile fields and mountains around the capital, and he had already had a plan in his heart.

In order to show its support for Hua'an's request for tuntian, the imperial court took out ten hectares of fertile land from the fiefs of several ministers of the dynasty and allocated them to the Northern Expeditionary Army.

One hectare of fifty acres, ten acres is only five hundred acres, such a little land is simply insignificant for the 30,000 horses of the Northern Expeditionary Army, and a team of people can be drawn out to organize these fields in an orderly manner.

However, Hua An still expressed his gratitude to several ministers of the DPRK and China, and then returned all ten hectares of fertile land, not a single acre.

Hua'an doesn't want an acre of fertile land, and a discerning person can see that it is too little, but for their own interests, all the ministers are silent, pretending not to know anything, and the ministers of the current dynasty who originally reluctantly ceded the land are even more relieved.

Hua An laughed at the pretending to be stupid and stunned by the ministers of the DPRK and China, because he fell in love with an excellent wasteland, which is not only vast in area, but also in a superior location, but it is still uncultivated, and it is an excellent land.

The wasteland is barren, it is difficult to grow abundant grain, and all the ministers of the imperial court are puzzled by Hua'an's request, but since Hua'an has asked for it, the imperial court will push the boat along the river and allocate all this wasteland that no one wants to the Northern Expeditionary Army for tuntian.

Located on the south bank of the river north of the capital, the wasteland is a perennial drought where weeds do not grow tall, and the low-lying areas closest to the river are flooded when it rains so much that crops cannot be grown.

However, this kind of barren land in the eyes of ordinary people is a treasure of feng shui in the eyes of Hua'an, as long as it is used well, it can be transformed into a land of fish and rice.

Hua'an roughly calculated that this piece of land is several thousand hectares, and the number of acres converted into acres is no less than 100,000, which is enough for the Northern Expeditionary Army.

To get so much tuntian land, Hua'an was naturally ecstatic in his heart, but the soldiers of the department did not understand very much, they and those court ministers, they all thought that this was barren land, of course, some soldiers had complaints in their hearts, they thought that soldiers should eat imperial grain, why should they still farm, this is not a farmer?

For these two questions of his subordinates, Hua An explained them one by one.

First of all, the reason why Hua'an asked for Tuntian, one is to reduce the burden of the imperial court, after all, the imperial court raises too many soldiers, and the financial pressure is relatively large, and the second is to let the soldiers have a relaxing time, the training of day and night is extremely boring, and people will be irritable for a long time, and if a person's nerves are tense for too long, it is easy to get sick.

Secondly, for this barren land, Hua'an has been inspecting for a long time, for the ditch and ravine, grass and trees here are well understood, for how to transform this place into thousands of hectares of fertile land, Hua'an has conceived a beautiful blueprint, but most of the subordinate soldiers are big and coarse, for the beautiful blueprint conceived by Hua'an, can not be experienced at all, for this reason, Hua'an does not want to bother to speak.

After officially obtaining this land, Hua'an began to transform, sending his soldiers into the wasteland in turn every day, using the farm tools in his hands to transform the wasteland, and the rest of the soldiers continued to train in the camp.

For the low-lying places along the river, Hua'an originally planned to fill in all the heights, so that he would not be afraid of floods, but in the process of actual transformation, Hua'an was surprised to find that he was too naïve, such a vast low-lying land, if all the manpower is used to fill in, the amount of work is too large, even if the 30,000 soldiers of the Northern Expeditionary Army start construction day and night, it will take a year and a half.

For this reason, Hua'an decided to change the plan, leaving some particularly low-lying areas and transforming them into reservoirs for irrigation, and at the same time, fish and turtles can be farmed in them, which can be described as killing two birds with one stone.

In order to prevent floods that have not occurred in a century, stone cofferdams are built in those locations that are easy to be impacted by floods, so as to ensure that the fields are not washed away by floods.

At the same time, on the sorted wasteland, it is divided into one acre of land according to the Dajin standard, and a canal for irrigation is dug between several acres, and all the canals are connected together, all leading to the river and the reserved artificial reservoir.

The preliminary transformation, division, canal repair and other steps took three months to complete, and by this time the spring ploughing had long passed, and the Northern Expeditionary Army in Hua'an had not planted a single grain of grain, and naturally there would be no harvest after autumn.

However, Hua'an is already very happy to be able to transform the wasteland that no one cares about into a decent field, which can be regarded as a sense of achievement!

Tidying up the field is only the first step, the next step is to fertilize the field, you know, barren land can not produce good crops, only more fertilizer can get a good harvest.

Hua'an is not too worried about fertilization, after all, there are 30,000 soldiers under his command, and the daily manure produced by the battalion is a large amount, and pouring this manure on the newly renovated land will definitely greatly change the soil quality of the wasteland.

It's just that there are hundreds of thousands of acres of wasteland sorted out, and the dung of 30,000 soldiers is simply not enough to meet such a vast land.

To this end, Hua'an decided to take it step by step, first select 1,000 acres of fields to fertilize with all their might, and then deal with the remaining fields after the soil of these 1,000 acres of fertile fields is fertile.

At the same time, because it is not easy to irrigate some high places, even if large water wheels are used to meet the needs of crops, Hua'an has to change the planting mode, for the high places where there is a general shortage of water, adopt the method of planting drought-tolerant crops, and for some special water shortage, can not grow crops on the highlands, it is planned to transform into pastures, build fences nearby, and raise cattle and sheep and other livestock.
