The Ba family was able to spread their business throughout the Qin Dynasty, so they were naturally trustworthy. Three days later, more than twenty craftsmen were sent as promised.

These craftsmen were the first to supplement the craftsmen to the DAMO Academy, and this place will also become the strongest backing for the Qin Dynasty to conquer the world in the future. In the future, the Black Dragon Flag will be inserted into the place where the Black Dragon Flag is visible, and this is the place where the Black Dragon Flag is cast.

The DAMO Academy is divided into academicians, researchers, engineers, and craftsmen from high to low. Once you enter the DAMO Academy, you can be assigned to a separate courtyard, with 100 copper plates per month. The monthly fee is increased to 300 copper plates. As for researchers and academicians, it is even more amazing. You can apply for separate research funds at this level.

"From today, when you enter the DAMO Academy, you will really make a living by your ability. We encourage invention and creation. You will be the trendsetters who lead the progress of the Qin Dynasty..." Li Chen's long speech, but these words made the craftsmen in the audience feel a little confused.

The Damo Academy was the thing that Li Chen had most effort to prepare since he arrived in the Qin Dynasty. This place is just a prototype, but one day it will lead the times.

"Today is the first lesson since the opening of the DAMO Academy, so let me, the dean, throw the bricks and attract the jade."

"Look at this picture, this is the curved plow I improved based on the long straight plow of Daqin."

"The long straight plow is difficult to turn and the cultivated land is difficult to cultivate. The curved plow changes the straight plow and long shaft to curved and short shaft, and installs a freely rotating plow plate on the shaft. This will make the plow frame smaller and lighter, making it easier to turn and turn, and make it flexible to operate, saving manpower and livestock." Li Chen shamelessly prepared the curved plow that should have appeared in the Sui and Tang Dynasties.

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

"This curved plow consists of eleven components, namely, plowshare, plow wall, plow bottom, plow, plow arrow, plow shaft, plow tip, plow review, plow construction and plow plate." Li Chen continued.

Many craftsmen watched, and the picture was drawn very clearly, but everyone could not understand the font on it.

"Liuzi draws the picture on the blackboard, and I say you can write it." Liuzi cleverly copied the picture on the blackboard of the laboratory according to Li Chen's instructions, and marked the names and uses small seal scripts to mark the names and uses of each component.

"The curved plow increases plow review and plow construction compared to the long straight plow. If the plow review is promoted, the plow arrow can be pushed downward and the plowshare will be deep when it is penetrated into the soil. If the plow review is raised, the plow arrow will be pushed upward and the plowshare will be shallow when it is penetrated into the soil. The organic combination of the plow review, plow arrow and plow construction can adapt to the different requirements of deep plowing or shallow tillage, and standardize the depth of the plow land, which is convenient for intensive cultivation. The plow wall can not only break the soil, but also push the plowing soil to one side, reducing the resistance to the plough progress." Li Chen explained it according to what he wrote in the book.

"It's amazing, changing straight into curves is a clever craftsmanship!" These craftsmen are all skilled in the entire Qin Dynasty, so they can naturally understand it at a glance.

"It's so easy to make such a clever thing. I can make five sets in a day."

"I think it's OK to have eight sets."

"I have ten sets."

"I have fifteen sets."

"I have fifty sets." The craftsmen competed one after another.

Come on, that guy with fifty sets. Come over and let’s talk. If you can’t make fifty sets a day, you can get your head in your stomach.

In short, the curved plow was quickly made.

"Big ox, go and try this curved plow." Soon the first curved plow was born on the land of Daqin.

The big bull skillfully put the old bull in a curved plow. All of this was extremely familiar. Obviously, he was a farmer who was delayed by an ironclad.

Soon, a mu of land was plowed all over by a big cow.

"Stop." Li Chen called out to the big bull who wanted to plow again.

"Wow." The big bull strangled the old bull's reins.

"Boss, why do you want to stop me? I'm not tired yet." Daniu asked with a puzzled look on his face.

"The ox pulls the plow, why are you tired? I've said that plowing again, what's the use of plowing?" Li Chen looked at the big bull with a look of a fool.

"Boss, there is a saying that is good. There are only exhausted cows, no broken ground." The cow responded to Li Chen with an agreed look.

"In nonsense, I'll try you like a cow and tell me how I feel about using this new plow." Li Chen kicked the rough man and was so angry that he was so angry.

"I just said that the plow is not tired. Although this is a ox pulling a plow, this person has to control the direction. In the past, I had to rest several times with a straight plow, but I was not tired at all with a plow. Moreover, the plow can be fast or slow, deep or shallow, and the feeling of being buried in the soil is extremely comfortable. I want to plow a few times." Daniu talked seriously about his feelings, but Li Chen always felt that he was driving.

Seven days later, Ba Qing appeared in this place where she didn't want to appear again, and faced the person she didn't want to see. This was not the smartest among her business rivals, but she was definitely the thickest-skinned person.

"Sister Qing, we're meeting again." Seeing the visitor, Li Chen left and greeted him with a bright smile. This is the God of Wealth, how could he not smile?

"I also want to thank my brother for his care. If you have something good, you will think of your sister immediately." Ba Qing politely said without hitting the smiley person.

"That's the sister of our mother and my compatriots. I don't think about my sister or who I have good things." Li Chen said seriously.

“…”

Ba Qing felt a little dizzy in her mind, and she didn't hit the smiley face. Looking at the smiling face in front of her, she just wanted to slap her and suck her to death. She wanted to kill him, but the First Emperor couldn't stop him.

"Talk about the serious business, brother." Baqing said gritting her teeth. She just wanted to leave this ghost place after the serious business. She would never come again next time, never come again.

"Sister, you see, this is a curved plow, this is a water wheel, this is a flail, this is a pedal, this is..."

"Sister Qing, look, this pedal pestle is made of wood. There is a pit at one end of the long wood at the bottom. The grain to be processed is placed. The upper wooden arm is installed with a hammer. The person tramples on the other end, so that the hammer can pound the grain and remove the shell."

"Sister Qing, look again. The water truck is a water lifting irrigation tool. The truck is more than 10 meters high. It is supported by a 5-meter-long and 0.5-meter-diameter axle, which spreads radially around. The top of each spoke is equipped with a scraper and a water bucket. The scraper wipes the water, and the water bucket is filled with water. The river water rushes, and the spokes slowly rotates with the inertia of the water momentum. The water bucket is filled with river water and is lifted up step by step. At the top, the water bucket is naturally tilted, injecting the water into the ferry and flowing into the irrigated farmland."

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

Li Chen was very familiar and never tire of explaining the pictures of these agricultural tools to Ba Qing one by one.

"This curved plow only costs twenty copper plates."

"This water truck is a bit expensive, with eighty copper plates. It is very simple to assemble. It can be used in places with instructions and water..."

"The pedal and flail are cheap, only ten copper plates."

Ba Qing didn't know how he came here today, so he returned to the mansion in a daze. Although he was about to be dizzy by the nagging, fortunately he won a big business for the Ba family.

"Sister Qing, look..."

"Sister Qing, keep watching..."

"Sister Qing, do you want to see if I have a baby..."

All night, Ba Qing wanted to have magic sounds surrounded her mind.
