The Ba family can do business all over Daqin, and they are naturally believers. Three days later, more than 20 craftsmen were sent as promised.

These craftsmen are the first batch of craftsmen to supplement the Damo Academy, and this place will also become the strongest backing for Great Qin's conquest of the world in the future. In the future, the Black Dragon Banner was inserted as far as the eye could see, and this was the place where the Black Dragon Banner was cast.

The Damo Academy, from high to low, is divided into: academicians, researchers, engineers, and craftsmen. After entering the Dharma Academy, you can be divided into a separate courtyard, and there are 100 copper plates per month. The title of engineer has risen to three hundred copper per month, and it is even more difficult for researchers and academicians, who can already apply for separate research grants at this level.

"From today on, entering the Damo Academy is really relying on ability to eat. We encourage invention and creativity, and you will be the trendsetters who will lead the progress of Daqin......" Li Chen said at length, but these words made the craftsmen in the audience a little incomprehensible.

The Dharma Academy is the most painstaking preparation since Li Chen arrived in Daqin. It's just a prototype, but one day it's going to be ahead of the times.

"Today is the first lesson since the opening of the Dharma Academy, so it's up to me, the dean, to throw bricks and lead the way."

"Let's look at this picture, this is my Quyuan plough improved according to Daqin's long straight plow."

"The long straight plough is difficult to turn around, and the plough is laborious. The curved plough changes the straight wheel and long wheel to the curved wheel and short wheel, and the plow disc that can rotate freely is installed at the head of the wheel. This makes the plough frame smaller and lighter. It is easy to turn around and turn, and the operation is flexible, saving manpower and livestock. Li Chen was very shameless and did the Quyuan plough that should have appeared in the Sui and Tang dynasties.

As for this drawing, I'm sorry he was too lazy to draw it, and he didn't like it, so he tore a page directly from a junior high school history book.

"The plough is made up of eleven parts. That is, ploughshare, plough wall, plough bottom, plough press, strategy, plough arrow, plough wheel, plough tip, plough evaluation, plough building and plough plate. Li Chen continued.

The craftsmen watched, and the picture was drawn very clearly, but the font on it was not understandable to everyone.

"Liuzi drew the picture on the blackboard, and I said you write." According to Li Chen's instructions, the six sons copied the drawings onto the blackboard in the laboratory, and marked the names and uses small seals to mark the names and uses of each part.

"Compared with the long straight plow, the curved plough increases the plough evaluation and plough construction, such as advancing the plough evaluation, the plough arrow can be made downward, and the ploughshare is deep into the soil. 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. Li Chen explained according to what was written in the book.

"Wonderful, such a straight into a song, ingenious!" These craftsmen are all skilled craftsmen in the entire Great Qin Number, and they are naturally thorough at one point.

"It's so ingenious, but it's so easy to make. I can make five sets in one day. ”

"It's okay for me to think about it."

"I'm ten sets."

"I've got fifteen sets."

"I'm fifty sets." All the craftsmen have compared.

Come on, that fifty-suit buddy. You come and let's talk, you can't make fifty sets a day, and your head will be beaten in the stomach.

In short, the quyuan plough was quickly made.

"Big Niu, go try this curved plow." Soon, the first Quyuan plough was born in the land of Daqin.

The big ox skillfully put a zigzag plough on the old ox, all of which were very familiar, and it was obvious that he was a farmer who had been delayed by the iron.

Soon, an acre of land was ploughed by the big ox leading the old ox.

"Stop." Li Chen shouted to the big ox who wanted to plow again.

"Phew." The big bull grabbed the old cow's reins.

"Boss, what are you shouting to stop me doing, I'm not tired." Da Niu asked with a puzzled expression.

"Ox pulls the plow, what are you tired of. After talking about plowing again, what is the use of plowing. Li Chen looked at Da Niu with a foolish look.

"Boss, as the saying goes, there are only tired oxen, not ploughed ground." Da Niu replied to Li Chen with an agreed look.

"In nonsense, I'll try you like an ox and tell me what it's like to use this new plow." Li Chen kicked the rough man, and he was angry.

"As I just said, this plough is not tiring. It's an ox pulling a plow, but the man has to be in control. In the past, I had to rest several times to plough an acre of land with a straight plow, but I was not tired at all when I used this plow to plough an acre of land. And this plough can be fast or slow, deep or shallow, and the feeling of entering the soil is extremely comfortable, and I still want to plow it several times. Da Niu talked about his feelings seriously, but Li Chen always felt that he was driving.

Seven days later, Ba Qing appeared again in this place she desperately did not want to appear, and faced the person she desperately did not want to see. This is not the smartest of her business opponents, but she is definitely the thickest skinned.

"Sister Qing, let's meet again." Seeing the comer, Li Chen left and greeted him with a bright smile. This is the God of Wealth, how can you not laugh.

"Thank you brother for taking care of me, I immediately thought of my sister when I had good things." Stretching out his hand not to hit the smiling person, Ba Qing said politely.

"That's it, we can be sisters of the same mother, I have good things and don't think about my sister, who do I think about." Li Chen said seriously.

“……”

Ba Qing felt that his brain was a little dizzy, and he stretched out his hand not to hit the smiling face. Looking at the smiling face in front of her, she just wanted to slap down and slap her to death. I really wanted to kill him, but the first emperor couldn't stop him.

"Let's get down to business, brother." Ba Qing gritted her teeth and said, she just wants to leave this ghost place as soon as possible after talking about business, and she will never come again next time, never again.

"Sister, look, this is a quyuan plow, this is a waterwheel, this is a flail, this is a stepping mill, this is a ......"

"Sister Qing, you see, this treadmill is wooden, there is a pit at one end of the long wood at the bottom, put in the grain to be processed, and the hammer is installed at one end of the long wooden arm, and the person steps on the other end, so that the hammer pounds the grain and takes off the husk."

"Sister Qing, look at it again, the waterwheel is a tool for lifting water for irrigation, the car is more than 10 meters high, and it is supported by an axle with a length of 5 meters and a diameter of 0.5 meters, which is supported by 24 wooden spokes, which are spread out in a radial shape. Each spoke is topped with a scraper and bucket. The scraper scrapes the water, and the bucket fills the water. The river rushed, slowly turning the spokes with the inertia of the movement of the water potential, and one by one the buckets filled with river water were lifted up step by step. At the top, the bucket slopes naturally, pumping water into the aqueduct and into the irrigated farmland. ”

"Sister Qing, you keep watching. Flail ......"

Li Chen was very familiar with it, and took the trouble to explain to Ba Qing the drawings of these farm tools one by one.

"This curved plough only costs twenty copper plates."

"This waterwheel is more expensive, eighty copper plates, the assembly is very simple, there is a manual, and it can be used wherever there is water......"

"Treading and flail are cheap, only ten copper plates."

Ba Qing didn't know how he came over today, and returned to the mansion in a daze. Although the whole person was about to be dizzy by the chatter, fortunately, he won a big business for the Ba family.

"Sister Qing, look ......"

"Sister Qing, you continue to watch ......"

"Sister Qing, I have a baby, don't you look at it......"

Throughout the night, Ba Qing's head was surrounded by magic sounds.
