A light short curved plow, also known as Jiangdong plow. However, it has nothing to do with the Koto of this era. It first appeared in the Dongjiang area in the late Tang Dynasty, and its appearance is a sign of the maturity of the Chinese nation's farming tools.

"We are using this kind of long straight plough at this time," In the arsenal, let alone taking out a coupling plow, when to take out Guan Erye's Qinglong Yanyue Knife, Ma Chao will not be surprised at all. After all, arsenals are now all-encompassing. As he spoke, Ma Chao squatted down, pointed to the coulter of the long straight plough and continued: "This kind of long straight coulter causes the turning back when ploughing the land to be inflexible and laborious, so the efficiency is not very high. ”

"The lord wants to improve this coulter?" Zhou Maitian had little interest in the columbus and the coulter, and was still immersed in the experiment of the cylinder car. The person who said this was Zheng Hun, who was more tolerant of his thoughts.

"That's right," Ma Chao pointed to the river simulated by Zhou Maitian at this time and said: "As I said just now, the good is like water, but it can spread the hard famous rivers and mountains. Does Gong Wen know why? ”

Zheng Hun's face began to be solemn, he stared at Zhou Maitian carefully and poured water over and over again with the broken basin, his brows furrowed, but finally he replied dejectedly: "The humble position is shallow in learning, and it is difficult to reach the lord, and I hope the lord will make it clear." ”

"If the water does not fight, it infiltrates all things. And this ploughing is the same reason. As long as we can imitate the shape of the long straight coulter in the shape of a water flow, the plough can swing during operation, which is maneuverable, easy to plough, and light and soft, which is conducive to maneuvering......."

Hearing Ma Chao say this, Zheng Hun seemed to have some understanding, he got up and ran to Zhou Maitian, scooped up a bowl of water from the basin, poured it on the ground, and wanted to see what shape the water was. And Ma Chao felt a little guilty at this time: although Qu Yuanli does have something to do with the paddy fields in Jiangdong, is it a little too hateful for him to fool Zheng Hun like this?

Sure enough, after Zheng Hun sprinkled a few bowls of water, he still walked over with a sad face, and said ashamedly: "Lord, I really don't know the shape of this water.......

"The flow of water is invisible, and how can it be simulated. However, as long as the long straight plough is changed to a curved short plough, the soil turning efficiency can be greatly increased. And ......." Ma Chao squatted down again, pointed to the bottom of the long straight plough and said: "Here, you can also increase the plough evaluation and plough construction, such as advancing the plough evaluation, you can make the plough arrow downward, and the ploughshare into the soil is deep." If the plough is raised, the plough arrow is upward, and the ploughshare is shallow when it enters the soil. The organic combination of plough evaluation, plough arrow and plough construction can adapt to the different requirements of deep ploughing or shallow tillage, and can standardize the adjustment of cultivated land depth, which is convenient for intensive cultivation. The plough wall not only breaks the soil, but also pushes the ploughed soil to one side, reducing the resistance of the plough forward. ”

Listening and listening, Zheng Hun already admired Ma Chao so much: "Isn't the lord really destined for heaven?" Why do you not only know the mysteries of iron, refined salt purification, and glass, but also know so much about farming......

Ma Chao's face was already as thick as the city wall of Fufeng, and he didn't blush at all. On the contrary, with an expression of melancholy and hatred that iron does not become steel, he said with a little sadness: "Wenshan, everything in the world, there is something to learn and improve. I'm not a mortal, but I have more observant eyes and a thinking brain than you. And you, as a master of silver in the arsenal, are only working behind closed doors in this ten miles of land, which is really ......."

"The Lord has taught him a great lesson, and he has taken his humble duties to heart. In the future, I will definitely see more and think more and live up to the expectations of the lord. Zheng Hun kowtowed to blame himself, that look was quite pious.

"Well, not only you, but all the craftsmen of the arsenal must have this idea of innovation and improvement. The promotion and salary increase system of our arsenal is not written out to make everyone look forward to it....... There is nothing to be desired. "As soon as he got it, Ma Chao almost even said the idiom 'Wangmei quenches his thirst', but fortunately, he thought that Boss Cao had not fooled his subordinates at this time, so he changed his words in time.

"I know." Although these words were extremely plain, Ma Chao believed that Zheng Hun had already remembered them in his heart. And through his words and deeds as a technical director, presumably the innovative thinking of the entire arsenal will gradually improve. As a result, Ma Chao was happy in his heart, and said: "Well, you must make these two things, the cocoon and the Quyuan plow, before the spring ploughing next year, for the people of Yongzhou to use only, and the craftsmen are insufficient, just ask Han Feng for it." As for the cylinder car, I will first set up two pilot projects, and then I will naturally let the newly established Ministry of Industry take charge of this matter. ”

After saying this, Ma Chao was planning to go back. But Zheng Hun suddenly remembered something, and used a grappling hand no less than Zhou Maitian, grabbed Ma Chao's cuffs and said: "Lord, the chariot you sent a few days ago has been thoroughly studied in the arsenal, and some small improvements have been made, I don't know ......."

"Oh?" Hearing this news, Ma Chao's eyes lit up, and he said, "Lead the way ahead!" ”

As he spoke, he glanced at Zhou Maitian, who was still playing in the water, and Ma Chao smiled weirdly: This guy, it seems that he will have a snack in the future. However, should he be sent to the Ministry of Engineering as a technical supervisor, or should he be given a coach in the Ministry of War?

Giving up the immature idea in his mind, Ma Chao had already crossed the forging house and came to the warehouse, pushed the door and saw that what was in front of him was the heavy rush car led by Dong Cheng at the time of the battle in the dock!

However, after careful observation, Ma Chao found that this heavy rush car was indeed improved, and the halberd in front of the body was replaced with three large lances, one long and two short, to ensure the continuous impact power of the chariot. The straight stab on the wheel has also been changed to a Su Tie barb, which is not only more powerful in breaking defenses, but also has a lot more lethality.

What surprised Ma Chao even more was that Zheng Hun and Pu Yuan, two cold-blooded butchers, actually added another seat to the side of the driver, and placed a simple version of the ballista in front of them! It is conceivable that once such a chariot strikes, all it takes is to put on a line of formation and launch a suicide attack, and no matter what kind of elite troops it is, they will be terrified and scattered!

Of course, in other defensive aspects, Zheng Hun has also modified it, making its entire tank like an ancient version of a tank, strict and impregnable, such a violent visual impact, which made Ma Chao imagine the terrifying power of these tanks after they were put into the battlefield!

It wasn't until he watched it over and over again that Ma Chao realized that Pu Yuan and Han Feng were also present. As a result, Ma Chao opened his mouth and asked Han Feng: "With such a chariot, what does the Ma family have now?" ”

Han Feng's face darkened for a while, and he was very speechless at Ma Chao's question: "Lord, this is the first chariot after improvement. If the improvement is carried out as soon as possible, there should be about 50 vehicles in 10 days. And if it is directly produced by the Ma family, I am afraid it will take a while, after all, the manpower of the arsenal is already a little insufficient........"

"Fifty?" Ma Chao sighed: "Fifty cars can almost affect a small battle....... It seems that the Ma Arsenal is about to usher in a second expansion. ”

When Han Feng, Zheng Hun, and Pu Yuan heard this, they couldn't help but feel joy on their faces, and they clasped their fists and said in unison: "The lord is wise!" ”
