Ma Tan passively accepted a lot of things because of the experience in the dream world in those years.

Although he himself has never dared to believe it, in his mind, the knowledge and concepts that have been ahead of him for more than 2,000 years are working imperceptibly.

Therefore, Ma Yan's knowledge and vision are not comparable to those ordinary classmates, even if they are demons such as Zhuge Liang and Pang Tong, they are not as good as them.

Fortunately, Ma Jian has completely changed his personality and no longer likes to be public, which does not make him special.

At the end of the Han Dynasty, the number of private schools exceeded that of government schools, because the political situation at that time was unstable, and the local government used all the funds for military affairs, and the number of students accepted by government schools was very limited, and there were few opportunities for scholars to enroll.

Even in Jingzhou, which is relatively stable, Liu Biao, who attaches great importance to education, is in charge, and the official school he founded can accept less than 100 students.

At that time, the government allowed private schools to be opened, which was also used to make up for the lack of official schools, but private schools expanded day by day, and by the end of the Eastern Han Dynasty, more than 60% of the students were accepted.

Pang Degong and other great Confucians, co-founded private schools, are more famous than Taixue at that time, because since Dong Zhuo's dictatorship, the Taixue of the imperial court has existed in name only.

Scholars enter the famous private school, learn from the Confucianism, and can also enter the official as an official, or serve as a staff member for the scholar officials, so the famous private school is more sought after.

The days fly by, a year passes quickly, although Ma Tan deliberately keeps a low profile, but if he wants to graduate smoothly and be recognized by teachers and classmates, he still needs to show some real talents!

Although his talents are all related to what he has learned, he is still more prominent in front of so many geniuses and demons in Lumen Academy.

Because he also likes military strategy, Ma Jian showed extraordinary talent, and he became close friends with Zhuge Liang, Pang Tong, Xu Shu, etc.

In this year's collective learning, Ma Tan has gained benefits, not only academic achievements, but also a lot of social practice and experience, which is an all-round improvement.

The annual examination of Lumen Academy was held as scheduled, and Ma Jian completed his studies with excellent grades and returned to Majiahe to study on his own.

Ma Tan is already sixteen years old, and there is nothing serious about it except for reading and practicing martial arts one day, and he can't sit still.

Because his brothers, all around the age of sixteen, took charge of the family alone, and their achievements were amazing, and they did a lot of things for the Ma family.

Although Ma Tan is the youngest in the family and is very favored at home, his hidden desire for expression makes him unable to study with peace of mind.

Although Ma Tan is a top student of Lumen Academy, he prefers military strategy in the academy, and his reading is mainly based on military books and war strategies.

What he has learned is really not helpful to his family for the time being, and it is a bit of a taste of not being able to write or do anything, which makes him quite embarrassed!

Fortunately, he still has a record in the book of heaven in his dreams, and for more than a year, he has some new feelings every time he looks through it when no one is around.

He has been thinking about the book in his dreams, and wants to confirm some of the things in it, and use some feasible techniques in reality.

In the past, although I lived alone in Lumen Academy, I didn't have the conditions to do other things, but now when I return home, when Ma Tan is practicing literature and martial arts, I will look everywhere to see what things can be used now!

After all, if you don't use anything, it's best that there is no market, and now people can't even eat enough to eat, so you just build him a car, and it's better to have a liter of rice!

On that day, Ma Jian followed his eldest brother Ma Bo often watched him inspect the farm, the Ma family had a lot of fields at that time, and it was impossible to rely on manpower to plough the land, and it was already mainly the use of animal power, and the family raised a lot of cattle and horses for arable land and transportation.

Seeing the old farmers plowing the land in the field, they use a long and heavy straight plow, and when plowing the land, the turning back is not flexible enough, and the turning of the soil is laborious, and the efficiency is not very high.

Ma Jian remembered the Quyuan plow in his dream, which has the advantage that the plow body can swing during operation, which is full of maneuverability and easy to plough. And it is light and soft, which is conducive to maneuvering, so the short curved plough is also suitable in Majiahe.

As soon as Ma Tan saw that the Quyuan plough family could use it, he was moved at that time, so he grabbed the eldest brother and drew a sketch on the ground, explaining to the eldest brother the benefits of using the Quyuan plough to plough the land.

But Ma Tan's mouth was dry, but Ma Bochang was confused, because his specialty was the cultivation of crops, and he couldn't operate the straight plow, so he had no concept of the benefits of the curved plow.

Ma Jian was helpless, and remembered that the second brother was a skilled craftsman, and there should be no problem with him making this quyuan plow.

After returning home, Ma Jian learned a lesson this time, thinking about the function of this quyuan plow, and the second brother may still not be able to tell, so he found a piece of silk, drew a sketch, and let him make it directly.

When he got up the next morning, Ma Tan, as usual, practiced his marksmanship a few times, hurriedly finished breakfast, and blocked the second brother directly at the door of his house.

The second brother Ma Zhongchang, when he heard that Ma Jian asked him to build tools, he didn't shirk at all, and directly took Ma Jian to the workshop.

Worthy of a skilled craftsman! Ma Zhong often took the drawings over, but after a cursory look, he was able to immediately see what they were and guess what they were used for.

He nodded as he watched, and occasionally let out an exclamation, as if he saw the mystery of the design, but asked what material the parts were made of, and after a little consideration, he said to Ma Tan:

"This is also a plough for the ploughland, right? It looks much more dexterous than the original! You go back first, I still have some work to do in the past few days, and I should be able to do it in ten days. ”

Ma Tan originally thought that the second brother mainly did carpentry work, and the two ploughshares were ironwork, and they had to find another blacksmith to make them. So he said to Ma Zhongchang:

"Second brother, this thing is not in a hurry, those two iron ploughshares, why don't I take them to the town and find a blacksmith to make them?"

Ma Zhongchang was full of confidence but replied: "Fifth brother, although the design of your plough is exquisite, this little work is not difficult for me, you just wait to pick up the goods!" ”

It turns out that today's craftsmen will not be satisfied with learning a technology, they have time to learn everything and tinker with everything, which is the so-called "art is not pressing".

Ma Yan's second brother, although he is the best carpenter, whether it is a blacksmith's work or a carpenter's work, he can do most of it.

Ma Tan is also not easy to see, for fear that the second brother will mistakenly think that he is urging him, except for going out in the morning to practice a few marksmanship, the rest of the time he locks himself in the house to read the book of heaven.

Ma Tan was not allowed to wait for ten days, and on the morning of the eighth day, Ma Zhongchang sent Quyuan plough to the door.

Ma Tan looked at the curved plough he designed, the second brother is worthy of being the best craftsman in a radius of hundreds of miles, this craftsmanship is really good, the curved plow, I don't know where he found a crooked neck tree, the appearance is completely no different from the drawings.

The wood-made part, even though the plough is made in several parts and then assembled, looks quite sturdy!
