"I've seen master Xue and WAN join the army."

"Hello, master Bi."

After breakfast, Xue Lang joins Wan Siming and goes directly to the workshop to see how the plough is made. Xue Lang asked master Bi, "where is the progress of plowing?"

Master Bi said, "Er Niu, Xiao Lao er's apprentice, has made a finished product. Please have a look at it. Is there any difference from what you have seen?"

"Just make one? Working all night? Didn't you have a rest yesterday? "

Xue Lang asked in surprise. Master Bi said with a smile: "craftsmen like this, they want to make good things. In the words of scholars, what is it called seeing..."

Master Bi can't remember for a moment. Xue Lang laughed: "happy to hunt!"

"Yes, yes, I'm glad to be hunting."

Although he was reminded to say it, master bi was still smiling. He didn't feel embarrassed or embarrassed. He had a natural look. Xue Lang nodded in his heart and said, "when the plough is finished and the standard is set, I will ask you for your help."

"The little old man thanks Xue Zhubo first."

"That's what I should do. My rule is that people who do things have rewards. "

"It's a good rule. It's down to earth."

Laughing and joking, he walked into the workshop. The young man with red and swollen eyes stood at the door and looked at him eagerly. Seeing Xue Lang coming, he saluted Xue Lang with a look of excitement on his face: "I have seen master Xue, and I have seen Wan join the army."

"Excuse me, are you er Niu?"

"Here it is."

The excited words are not easy to say. Xue Lang said with a smile: "it's not necessary to have such good knowledge. It's OK to know the characters. Second question, can you do arithmetic? "

Er Niu shook his head. Xue langlue said with some regret: "I know that you want to learn the drawing method from me, but to learn my method, you should not only be able to read, but also have the basis of arithmetic and geometry. Otherwise, the size drawn will not be accurate. In fact, my method is more suitable for drawing asymmetric objects. What you do is symmetrical. In fact, there is no need to use my method. "

Er Niu seems to be a little reluctant: "arithmetic small know where to learn, but how is this geometry knowledge?"

What is geometry? This question has never been thought about. When asked, Xue Lang was dumb, scratched his face and thought for a moment, and said, "geometry is the study of the spatial shape of an object. For example, look at this plough, this section It's called a cylinder in Geometry... "

Xue Lang explained to him roughly, er Niu was a little confused and didn't know if he understood. Xue Lang patted him: "you haven't learned it. It's not surprising that you don't understand. Go to have a rest first. I'll take someone to try plough."

Er Niu's eyes at Xue Lang are somewhat pitiful and unwilling, but they can't do anything if they can't meet the requirements of study. They can only rest stiffly.

When the party arrived at the edge of the farm, Wan Siming asked someone to go to find the ox man and the cattle.

after a while, a middle-aged man dressed in old short brown followed the two oxen and saluted Xue Lang and them before going to plough.

"This plough needs only one ox, not two."

As soon as he said this, Niu Fu's expression was happy: "is it true that master Xue said it? Can a cow pull? That's good. It saves a lot of animal power. "

Xue Lang laughs: "try to know."

"Here it is

Niufu is an old type. When he saw the plough, he saw the advantages of it. His eyes were full of joy. He went to carry the bent shaft plow first and said in surprise, "this plow is so light and light. This weight is really enough for only one cow."

Er Niu is very careful when choosing materials. He chooses light, strong and cheap wood. The heaviest part of the plow is the metal part. This weight is heavy for humans, but light for cattle. Niufu often plays with these things. Naturally, you will know when you lift it.

Put the plow on the cow, the Cowman called out and drove the cowboy field to plow up. The cattle were obviously fed and domesticated skillfully. With a "moo", they bowed their heads and began to work. It's a long way out.

Xue Lang built a canopy to remind Niu Fu: "when you turn, you don't need to use the plough. If you hold on a little bit, the plough can turn."

"Here it is

As expected, when it comes to the turn, the ox with the plow will skillfully turn the corner, without having to lift the plow to turn the head as usual.

Wan Siming, who was also very concerned about the trial situation, clapped his thighs excitedly: "it's done! From then on, the farming situation in Datang will be greatly improved. "

Excited finished, just look at Xue Lang with bad intention, embrace fist to apologize: "it is subordinate arrogation, disrespectful."

Xue Lang shook his head. He could understand the excitement of people with farming civilization when they saw more labor-saving and efficient farming methods. In fact, he was quite excited, and made another contribution!
