After driving the donkey to plow the field for more than three hours in one breath, Zhang Ran and his mother temporarily stopped and took a rest, and by the way, the donkey also took a breath and eased it.

Turning around and looking at the large area of ​​plowed fields behind him, Zhang Ran couldn't help but smile and said to his mother: "Mother, how do you think my new plow is like? Is it better than the old plow before?"

Zhang Li looked into the distance for a moment, and a smile appeared on his beautiful face. He nodded at Zhang Ran, and said with great relief: "In just one hour, we had plowed three or four acres of land, which was three or four times faster than the man-made plowing of fields in previous years! Ran, the new plow you made is really amazing! It is not worse than the previous ripping machine!"

Immediately afterwards, Zhang Li looked down at the new plow in front of Zhang Ran, and couldn't help but exclaim: "I didn't expect that I just loaded a few pieces of wood and two more straw ropes. The plow was so fast in plowing the land! It was so amazing!"

Zhang Ran said with a slight pride: "Mother, although these three small things are inconspicuous, their functions are very practical. They can not only increase the depth of the plowing land, but also greatly speed up the plowing speed! At the current speed today, under the same conditions, the effect of the new plow is more than twice as good as the old plow! I expect that at this speed, we can plow all ten acres of land in two days! We can plow all twenty-five acres of land in five or six days!"

"Well!" Zhang Li's eyes looked at her son softly, and said proudly: "All the people gathered in us said that my family Ran'er is the smartest young man in our Zhangli in a century! In my mother's eyes, this must be said that there are fewer ones. At least my family Ran'er is the smartest in Xiting in a century!"

"Is that so? Hehe..."

Hearing his mother's praise, Zhang Ran's face flashed with a hint of redness, and he couldn't help but touch the back of his head awkwardly and giggled.

...

After about half an hour of rest, the mother and son started a new round of farming operations, which lasted until the evening before they got on a donkey cart and went home.

According to his mother Zhang Li, this speed is about twice as fast as the old plows are now commonly used. When cattle or donkeys are used as animal powers, it is about twice as fast.

If human-powered plowing and plowing fields are used as a reference object, the effect will be better and more obvious, and the speed will be at least three or four times faster.

Judging from the current situation, Zhang Ran's new plow has been successfully improved. Although it is only a straight plow that is slightly behind the curved plows in later generations, it is enough to greatly shorten the time required for cultivated land.

However, if you want to plant wheat in the winter, it is not enough to just plow. Zhang Ran still lacks one very important thing now, that is, the cart!

In this era, there is no such thing as a car. People's methods of sowing seeds are mainly based on human resources, and the speed is very slow.

Zhang Ran, the inventor of the car, remembers a little, as if it was Zhao Guo, the agronomist who was entrusted with important tasks in his later years and was known as "Grandpa Yuan of the Han Dynasty".

Unfortunately, Zhang Ran was not very clear about whether Zhao Guo was born now, but he knew that Emperor Wu of Han lived to be seventy years old. By the time Emperor Wu of Han was in his later years, it would be at least decades later. Zhang Ran couldn't wait that long!

Although making a car in advance would steal Zhao Guo’s credit and make him feel guilty as a “plagiarist”, this is by no means a reason for Zhang Ran to stop moving forward!

So, he decided that even if he was shameless, he would have to get the car out now!

However, a little different from a plow is that the cart does not have a ready-made reference, so it is a little more difficult to make than the plow.

But to be honest, the difficulty of the car is actually very limited, because like a plow, the main components are made of wood, and only copper and iron are required for shovels.

During this period, Zhang Ran made new types of grinding machines and new plows with his own hands. The carpenter's craftsmanship has soared, and it is not difficult to build a frame of a car.

...

After spending five days, I finished plowing all the 25 acres of land in my family.

With free time, Zhang Ran, according to his memory, used the existing wood and axe tools at home, and spent a day creating the main frame of the car, the stool and the legs of the car.

Due to personal skills, Zhang Ran’s frame of the car is not very standard. From a distance, it looks more like three large funnels side by side...

However, the appearance is slightly worse, but the production principle is basically the same as that of later generations of carts, so I think the effect will not be much worse.

After that, I drew a sketch of the shovel in my memory on the wooden board, and took this sketch to Xinfeng County. The blacksmith there asked to create three shovels according to the sketch.

Although the appearance of the shovel is slightly different, the overall structure and difficulty of making are very similar. Although the blacksmith in Xinfeng had never made such things before, with Zhang Ran's sketches and descriptions, with his rich experience in making iron and plowshares, the blacksmith still made the shovel that Zhang Ran needed in a very short time.

After the shovel was made, Zhang Ran considered that he might have to promote shovels to the people in Zhangli on a small scale in the near future, so he placed an order for thirty shovels in the blacksmith shop on the spot.

Then, Zhang Ran took the newly built shovel as a sample and went to all the blacksmith shops in Xinfeng and placed orders with them separately in order to create enough shovels in the shortest time.

After working for more than a long time, when Zhang Ran returned to Zhangli with the shovel, it was almost evening. After Zhang Ran arrived home, he took some more effort to assemble the shovel with the shovel that had been built before dark, so a freshly baked cart was built!

After the cart was built, Zhang Ran took Sumai seeds and cart bought from Xinfeng the next morning and drove the donkey cart to the field with his mother.

...

After some experiments, Zhang Ran's new car has also had a very good effect. Although due to personal craftsmanship and the workmanship is a bit rough, the effect is not much worse than that of later carriages.

With this cart, the speed of the Zhang Ran family sowing has greatly increased many times. It took more than 20 acres of land and all planted them in less than three days.

It took nearly ten days to start from improving the new plow until the cart is drawn out, and then planting all the 25 acres of land at home on the wheat.

Such a fast farming time shocked Zhang Li, the mother who was farming with Zhang Ran. You should know that if it were spring farming in previous years, the farming time would take at least about a month!
