"This, how is this drawn?" Li Jing was tall and tall, and although he was blocked by someone in front of him, he still saw the thing on the paper over everyone's heads, so he asked curiously.

For Li Jing's question, everyone looked at Li Muyun, because this question seemed to be the only one present who could answer.

Li Muyun took a deep breath, revealing a smug expression, and just wanted to drag two sentences, but his ass was already kicked by Li Er: "Say it quickly, what are you rubbing." ”

It's really unpopular, such a big emperor always likes to kick other people's butts, and he doesn't know how to be a little more restrained, Li Muyun stumbled for a moment, and said with a frown: "This is actually drawn with a ruler with a more precise scale with a compass, it's not a big deal." ”

"Fart, I know this with a ruler, what I want to know is why this line is so thin, why this line is so straight." Although Li Er was very shrewd, his words fully exposed the ignorance in his heart.

If he really knew how to draw with a ruler, then he shouldn't ask why he painted so straight, Li Muyun pursed his lips with disdain, but a flattering smile appeared on his face: "Your Majesty Shengming, in fact, this thing was painted by me with charcoal strips, which is why it is so thin." ”

"Charcoal? Can charcoal strips be used for writing? The eldest grandson Wuji muttered, but quickly reacted, it seems that the charcoal strip can really be written, but it is generally not used.

However, Li Er didn't care about these side matters, put the two pieces of paper in his hand and looked at them carefully for a long time, and then handed them back to Li Dejian: "I really think it's a treasure, it turns out that it's just some strange tricks." ”

Tricks? Li Muyun suddenly didn't like to listen to it, and he didn't care whether Li Er was happy or not: "Your Majesty, what you said is not right, although this mechanical drawing is not an elegant thing, but its use is irreplaceable." ”

"The reason why Qin was powerful back then was that it unified weights and measures, and the car was the same as the track, and the same text, and now we are building a knife with a slight difference in length and weight, not to mention complex machinery such as bed crossbows and catapults."

"Eight or nine hundred years ago, our ancestors knew the principle of uniform standards, shouldn't we pass on this concept now? For example, if there are standard cartographic methods and all ordnance is built according to a uniform standard, then on the battlefield, after a certain ordnance is destroyed, it is completely possible to dismantle the broken part and replace it with the undamaged parts of the broken ordnance, so that the army can continue to maintain its combat effectiveness. ”

Li Er surprisingly didn't get angry this time, but listened carefully to Li Muyun's bragging, forcing there, it was the first time he had heard of the concept of modularity, but this didn't mean that he didn't know the benefits.

Li Muyun used standardized drawing, by the way, to talk about simple modular production, looking at the omnipotent Tang Emperor dumbfounded and speechless in front of him, which really made him feel comfortable from the bottom of his heart.

It's just that Cheng Biting Jin's old man suddenly spoke on the side at this time: "Boy, you don't brag there, we didn't have any mapping in Datang before, so won't we work as a supervisor?" Didn't you build a good weapon? Good ordnance? ”

I have to say that Cheng Yanjin and Li Muyun are really a perfect match, both of them seem to have a good physique, one person says something is right, and the other must raise objections, even if it is unreasonable, then it must be said.

Li Er and the others had actually realized the importance of Li Muyun's point of view just now, but at this moment, Cheng Yanjin suddenly spoke, and everyone wanted to see how Li Muyun would answer.

Li Muyun was also a little unclear about the situation at this time, he really didn't know whether Lao Cheng was helping himself or dismantling himself, so he smacked his lips and said: "Standardization and modularization represent the progress of the times. The simplest example, Brother Dejian, you should have received the steel ingots sent by Shuozhou, I don't know if you see the key? ”

"The weight is the same, just find two pieces, even if it is different batches, the weight difference is less than three dollars." Li Dejian glanced at Li Muyun and replied.

Three coins is the weight of the three copper coins combined, which is almost negligible for each copper ingot weighing ten catties, that is, the weight of these steel ingots transported from Shuozhou is almost exactly the same whether it is a month ago or half a year ago.

Li Shimin's originally calm face finally changed, and he glanced at Li Dejian and asked, "What you said is true?" ”

"It's true!" Li Dejian nodded heavily: "This minister has personally tried it no less than ten times, and the result is the same every time." ”

What is a standard? This is called the standard, it turns out that unconsciously, Li Muyun, this kid, has been promoting the standardization of the operation, ten catties of steel ingots, as long as there is no problem in the processing process, then the weight must be the same.

After listening to Li Dejian's assurance, everyone couldn't help but be curious, and regardless of the purpose of coming here, they came to the warehouse where the steel ingots were stored under his leadership, and went in to select their favorite steel ingots.

When he took it out, he immediately found that what Li Dejian said was true, and those steel ingots were really all one weight.

At this moment, Li Muyun was completely angry again, and Cheng Biting Jin pulled him over, and his rough big hands pinched his face, shouting while pinching: "You kid shouldn't have changed from a girl, right?" Otherwise, how could it be possible to make something so detailed. ”

Li Muyun broke free from Cheng Laomo's hands speechlessly, rubbed his pinched sore face and said angrily: "The surname Cheng, if you are jealous of my handsomeness, you can be direct, why use such dirty means." ”

"Ouch, you kid is capable, dare to argue with my old Cheng?"

Cheng Biting Jin is the master who is afraid that the world will not be chaotic, and it is not a little bit bad to talk about Li Muyun, seeing that the old goods are about to be spilled, the king of Xiaoyao County immediately flashed in front of Li Shimin, and said: "Your Majesty, the minister thinks that this standardized operation and modular production must be promoted, and only in this way can my soldiers in the Tang Dynasty have more sophisticated equipment to use." ”

Li Er pursed his lips slightly, his eyes swept over Jin and Li Muyun, and said with a strange smile: "Let's talk about this matter later, I see that Cheng Aiqing seems to have something to say to you, so I won't bother you." ”
