"I've seen Master Xue and Wan join the army."

"Hello Master Bi."

After breakfast, Xue Lang met with Wan Siming and went directly to the workshop to inspect the production of the plow. Xue Lang asked Master Bi: "Where is the progress of plough making?" ”

Master Bi said: "Xiao Lao'er's apprentice Erniu made a finished product, please Xue Zhubo take a look, is there any difference with what you have seen." ”

"Just make one? Rushed to work overnight, right? I didn't rest yesterday? ”

Xue Lang asked in surprise. Master Bi said with a smile: "Craftsmen are like this, if they have good things, they want to make them, in the words of a scholar, what is it called......"

Master Bi couldn't think of it for a while. Xue Lang smiled: "I'm happy to see Hunting!" ”

"Yes, yes, it's just to see the joy of hunting."

Although he said it only after being reminded, Master Bi still smiled, not embarrassed, not embarrassed, and his expression was natural. Xue Lang nodded secretly in his heart and said, "When the plow is finished and the standard is set, I will ask you for credit." ”

"Then the little old man thanked Master Xue first."

"That's what I'm supposed to do. My rule is that there is a reward for those who do things. ”

"This rule is good and down-to-earth."

Laughing, walking into the workshop, the young man with red and swollen eyes stood at the door and looked at it, and when he saw Xue Lang coming, he saluted Xue Lang with unbearable excitement on his face: "I have seen Master Xue, and I have seen Wan join the army." ”

"Excuse me, you're Erniu?"

"Whoa."

These excited words are not in good demand. Xue Lang smiled: "This is the second time we have met, I didn't see you so excited the first time, why did you get excited the second time?" Haven't I seen each other for a few days, and I've become scary? ”

Erniu was so ashamed that his face was flushed, and the more anxious he was, the more he couldn't say it, "I" had been for a long time, and there was no result for "me". Xue Lang patted him on the shoulder: "Okay, don't worry, I'm here today, let's talk slowly, let's go see the results of your overtime work first, finish it early and go to rest quickly, see if you boil your eyes, even if you are still young, you can't stay up like this, it will break your body and bones." ”

"Hey!"

The answer was loud.

Went in with Erniu, and in the spacious yard, there was indeed a Quyuan plough that had been made, Xue Lang went to take a look, and carefully compared the appearance of the Quyuan plough in his mind, and it was really exactly the same.

Looking up at the second bull's eye, he couldn't help but be happy: "Cheng, what I do is the same as what I've seen, the young man has good skills!" ”

Erniu smiled shyly, his eyes were full of confidence, and he was obviously very confident in his craft. Xue Lang nodded secretly, craftsmen must have this kind of self-confidence, if they don't even have confidence in their own craftsmanship, then they can't make anything good.

Xue Lang said: "Since I have made a finished product, then I will try it in the field first to see if there is anything to improve." If not, then I will ask the general for credit for everyone, and Erniu should remember the first merit. ”

Erniu's eyes lit up, and he hurriedly arched his hand towards Xue Lang and said, "Master Xue, if Erniu is meritorious, can you not want His Highness's reward?" ”

Xue Lang was surprised, and asked rhetorically: "You don't want the princess's reward, do you want mine?" ”

"Exactly!"

Erniu's eyes stared at Xue Lang with burning eyes, as if he was looking at a treasure trove. Xue Lang didn't say anything, and Master Bi shouted: "Erniu is presumptuous!" ”

Xue Lang waved his hand indifferently, and his brain turned around, what he had revealed here in Erniu was the drawings and perverted memory. If you can't learn from memory, then it's a drawing!

Xue Lang understood, looked at Erniu carefully, and said, "Stretch out your hand and I'll take a look." ”

Although Erniu didn't know, he still obediently stretched out his hand-

It was a pair of thick and powerful palms, covered with calluses and scars, new wounds pressed against old wounds, and there was a pale black layer in the fingerprint seams!

This is a pair of hands that do a lot of work.

Such a pair of hands appeared on a young man, representing his diligence and hard work, as well as the master's trust and importance to him.

Xue Lang nodded and said, "I know what you want, I have a few questions, first, are you literate?" ”

Erniu was surprised and delighted, and hurriedly said: "Back to the main book of Xue, I can read and write, but I can't write poems and articles." ”

"You don't need to be so good at learning, you just need to be literate. Second question, do you know arithmetic? ”

Erniu shook his head. Xue Lang said with a little regret: "I know you want to learn the method of drawing with me, but to learn my method, you must not only be literate, but also have a foundation in arithmetic and geometry, otherwise, the size drawn will not be accurate." In fact, my method is more suitable for drawing asymmetrical objects, what you do is symmetrical, in fact, there is no need to use my method. ”

Erniu seemed to be a little unwilling: "The arithmetic is a little bit younger, but what kind of knowledge is this geometry?" ”

What is Geometry? I had never thought about this question, but when I was asked at this time, Xue Lang was a little dumb, scratched his face and thought about it, and said: "Geometry is the study of the spatial shape of an object. For example, if you look at this plow, this paragraph...... In geometry it is called a cylinder......"

Xue Lang roughly explained to him, Erniu was a little confused, and he didn't know if he understood. Xue Lang patted him: "You haven't learned, it's not strange if you don't understand, let's go rest first, I'll take someone to test the plow." ”

Erniu looked at Xue Lang's eyes a little pitiful and unwilling, but he couldn't meet the requirements of learning, so he could only rest in a depressed manner.

When the group arrived at the edge of the farmland, Wan Siming asked someone to find a cowman and a ploughing cow-

After a while, a middle-aged man dressed in an old short brown came over with two ploughing oxen, and saluted Xue Lang and them before going to the plow.

Xue Lang hurriedly said: "This plough is good for one ploughing ox, not two." ”

As soon as these words came out, the cowman's expression was happy: "Is what Master Xue said true?" Can a cow pull? That's a nice thing, it saves a lot of animal power. ”

Xue Lang smiled: "Just try it and you'll know." ”

"Whoa!"

The cowman is an old man, as soon as he saw the plow, he saw the advantages of it, his eyebrows were full of joy, and he first went to lift the zigzag plow, and immediately said with surprise: "This plough is so light, this weight, really only one ox is enough." ”

Erniu was very careful when choosing materials, choosing light, strong and cheap wood, and the heaviest part of this plough is the metal part. That's a lot of weight for humans, but it's very light for cows. The cowman often fiddles with these things, so he will know it as soon as he lifts it.

Putting the plough on the oxen, the cowman shouted, and drove the cowboy into the field to plow, and the oxen were obviously fed and skillfully tamed, and after "mooing", they bowed their heads and began to work. After a while, I'll go out for a long time.

Xue Lang put his hand on the pergola and reminded the cowman loudly: "When you are about to turn, you don't need to get off the plow, you hold on a little, this plow can turn." ”

"Whoa!"

The cowman promised from afar-

Sure enough, when it came time to turn the plow, the plough carried the plough and turned the corner dexterously, without having to carry the plough and turn the head as in the past.

Wan Siming, who was also very concerned about the trial situation, slapped his thigh excitedly: "It's done!" From now on, the cultivation situation of my Datang will be greatly improved. ”

After the excitement was over, he looked at Xue Lang embarrassedly, and apologized with his fists: "It's a subordinate who has trespassed and is rude." ”

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