The first thing Chen Xian arranged for the hired laborers was to dig a trench thirty paces from the new city wall of Xinzhuangzi.

The trench was to be three feet deep, and the excavated earth was piled on the outside of the trench.

While the laborers were digging trenches, Chen Xian sent his mandarin duck team and crossbowman team to cut down four or five meters long wooden poles in the nearby woods in turn.

In order to prevent retaliatory attacks by mountain hunters, Chen Xian required that there must be more than two teams entering the mountain, they must be on guard, they must match the light and the dark sentry, and they must wear armor......

After the cut wooden poles are brought back, they are debranched, peeled, sharpened and stored for drying.

……

Chen Xian did not spend too much energy on the arrangement and management of these newly recruited laborers, he transferred a few people from the apprentices to form a simple management team, a manager, in charge of the overall situation, a supervisor, in charge of the quality and acceptance of the project, an accountant in charge of the project's account transactions, the salary of the labor, the rewards and punishments of the labor, but also need to be accounted for before it can be realized, a cashier, in charge of the money and grain, in strict accordance with the financial accounts to distribute money and grain.

After arranging the management team and clarifying his requirements, he let go and stopped paying attention to the matter.

Chen Xian focused his main energy on what was needed more for him.

For Chen Xian, the more important thing is the restoration and trial production of the horse-drawn heavy plough, and the production of screws must also be put on the agenda.

The recovery of the horse-drawn heavy plough is easier, and there is a sketch of the structure of the thing in the web writer's database, as well as a more professional and detailed description from a paper.

For a good engineer, it is sometimes possible to even rewind the design drawings of a machine with a single photo, let alone have a structural sketch and a detailed professional description in hand.

The horse-drawn heavy plough has two main points, one is the horse-drawn and the other is the heavy plow, which is certainly not nonsense, these two points are two quite important inventions in the development of Western agriculture.

Unlike cows, horses have a body structure that is not suitable for pulling pears without a proper harness.

The chest strap harness is one such crucial invention.

With the chest strap harness, the speed advantage of the Malali can be unleashed.

A heavy plough, or a double-wheeled heavy plough, is a type of plough with two small wheels on both sides, a vertical coulter in the middle, a horizontal ploughshare, and a plough wall used to shovel the soil and turn the mud over. The combination of the three not only enables deep ploughing, but also makes ploughing more efficient.

The advantage of the horse-drawn heavy plough is that it is deep and can turn out the furrow, which is fast and saves manpower.

However, he also had the disadvantage that the initial investment of this type of farming was high, a large two-wheeled heavy plough often required four horses to pull, and the price of the double-wheeled plough was also very high, which made it impossible for the average homesteaders to afford this input.

This high cost has led to the development of collective and intensive farms in Europe, because it is only through cooperation that the average homesteader can use this high-input and high-efficiency farming method.

According to the sketch diagram and description in the data, Chen Xian made a qualified two-wheeled heavy plough after several trial production and improvements, and the principle and structure of this thing are not complicated.

He uses wrought iron as the skeleton of the heavy plough, the axle, wheel and ploughshare are made of cast iron, and some parts with high precision requirements are cast, and the connection method is riveted, pin and keyway connection.

This kind of agricultural tools, which were invented in the tenth century A.D., are different from modern machinery, even the simplest machinery, have certain precision requirements, and this ancient agricultural tool has almost no precision requirements, and the difficulty of manufacturing is much lower.

Because the main body is made of steel, the weight of this heavy-duty tandem plough is quite large, and it deserves the title of heavy plow.

Chen Xian also designed the horse bra harness according to the data, this appliance is actually a teardrop-shaped neck sleeve, which is set at the end of the horse's neck, and the traction rope is tied to the middle and lower part of the neck sleeve, when the horse plows, the main pressure of the neck sleeve on the horse is on the horse's chest, not the horse's neck.

The neck sheath is padded with a thick layer of leather and linen cloth, which relieves the pain of the horse when pulling the plow, and helps the horse to exert more strength.

When Chen Xian successfully ploughed the ground with a wheeled heavy plough with four horses after many experiments, the plowshares that walked like flying and the soil that flew overturned were dumbfounded.

Chen Xian's 160 acres of land, of which about 50 acres have long been leased to some of the more difficult apprentices, and more than 40 acres have been leased to more than 20 families who have moved to Xinzhuangzi as promised, and there are still more than 70 acres left, which have been so barren.

Some of the elders of the apprentice's family couldn't see it, and asked the children and grandchildren who were apprentices in the Chen family to persuade Chen Xian not to waste the fields. Chen Xian always said that he was not in a hurry.

After the success of the heavy plough test, Chen Xian took the apprentices to plough the remaining more than 70 acres of land in less than two days, which is still because he and the horse did not have a tacit understanding in the first two days, even so, this efficiency is more than twice that of the ordinary double-ox plough in this era.

Of course, Chen Xian was able to match the horse in two days, and played most of the efficiency of the horse-drawn heavy plow, thanks to the fact that he was born in the countryside and used oxen to plow the land when he was a child; Second, after he opened a farmhouse, he raised horses and was familiar with horse nature; Thirdly, the horses he got by bribing Steward Yang and the second butler of the Bai family were all horses, which were relatively docile and easy to control.

In addition to the good efficiency of the double-wheel heavy plough, this structure is relatively easy to develop a double-ploughor or even a three-ploughshare parallel structure, which is large enough to improve the efficiency of cultivated land again, but to develop a double-plough or even a triple-plough structure, Chen Xian also needs to accumulate more mechanical technology.

By the time the 70 acres of land had been cultivated, the more than 30 newly recruited laborers had already completed the task assigned to them by Chen Xian to build the perimeter fence of Zhuangzi.

That's right, Chen Xian had the newly recruited laborers dig a trench thirty paces from Zhuangzi, in fact, to build a fence.

After the trench was dug, the dried pole was placed on the earthen wall on the outside of the trench with the tip facing outward, and buried in the trench at a forty-five degree angle to the ground, thus creating a new fence, at the bottom of which was a three-foot-high breastop wall, which crossbowmen, or more powerful long-range marksmen, could rely on to shoot against foreign enemies.

To the south of the wooden fence is a ten-meter-wide road, and in the fences on either side of the road are dozens of wooden nailed horses that can quickly block the gate three times if necessary.

……

Chen Xian handed over the task of sowing seeds to more than 30 laborers, and in the future, these more than 70 acres of land will be taken care of by these more than 30 people.

Before sowing, Chen Xian promised that if the average yield of this land could exceed two stones during the autumn harvest, then in addition to his monthly salary, he would also give an additional 30% of the total output as a reward to everyone.

The rewards are not evenly distributed, and how much each person will be rewarded will be determined by the few apprentices who manage the more than thirty people......

Thus emerged an agricultural company with management and agricultural workers.
