"What can you do that? It's just to make these things?" Li Zhi picked the pointer floating on the surface and asked casually. "That's right, look at these things, the error between them is definitely less than one millimeter. Why? It's just to make these things mass-produced, and can be produced on a large scale and flow-through basis. Take a thing for example, you should have seen all the steel crossbows in the Tang army now, right? Do you know? Now, if there is a problem with the nearly 10,000 steel crossbows used by the Tang army, you can choose one of the other 9,999 steel crossbows and replace the damaged parts! Niu?" I raised my eyebrows proudly. Unfortunately, a fool next to me who was not good at it came out and made me angry.

"Isn't this man sick? Just pick another one and use it!" The person who said this was Uncle Li's youngest son, Li Ming, a little boy who was only nine years old and has not yet been crowned king. After saying this, the chubby little guy tilted his head with a smug look. The King of Dai Li Jian and King of Zhao Li Fule grinned, and were very happy about the scammer. Li Zhi laughed and cried and picked up Li Ming with a smile, letting the guy sit on his lap, and slapped the little guy's fat ass: "Stupid talking nonsense to me, Master is asking questions."

Li Shen ignored Li Ming, his eyes were very bright, and he immediately realized an extremely important fact. "Jun Ge'er, what do you mean is that if a certain part of the Wuhan Research Institute is damaged, the same parts can be used to repair it at any time?"

"That's right, that's the reason." I nodded with a smile. Let alone Li Shen, Li Zhi also frowned with a serious expression: "Brother Jun, are you not kidding? Even big guys like the artillery from the Wuyan Institute can be replaced like this?"

I smiled confidently on the ground and nodded slightly. "Be good, if all the weapons of my Tang Dynasty were supplied by the Wushu Institute. Just this point, then I don't know how much money I can save every year in the Tang Dynasty." Li Zhi took a breath.

He was indeed right. The Tang Dynasty was indeed rich, but it was not as rich as that of the people's taxes at will. Moreover, in this era, the expenses of nearly 500,000 troops had to be maintained. It was not a small amount. The crossbows and various weapons of the Tang Dynasty often caused large siege equipment worth several or even hundreds of sieves to be turned into a pile of waste due to the damage of a certain part. Otherwise, it would have to be rebuilt as usual before repairing, and it took time and money. Sometimes it was even better to be discarded directly. After the weights and measures were re-specified by the Wushen Academy, whether it was a firearm that weighed thousands of kilograms or a light long-range weapon that was used by the Wu Ben Army, which weighed no more than two kilograms.

———————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

The maximum error of all parts in between is less than one millimeter. This is already the maximum accuracy that craftsmen of this era can achieve, and it is precisely because of this. Assembly lines and standardized production can be achieved.

"Tell you, this is the benefits of refining and refining weights and measures. Do you know?" I laughed. Li Zhi nodded, but Xuan Ji asked me with some concerns, "Brother Jun, if this happens, will all the weights and measures in the Tang Dynasty be lost?"

I glanced at Li Zhi: "Xiaozhi. You don't understand. Let me tell you why this precise weight and measure is only used in the Ministry of Industry and the Wuhan Research Institute. Do you know? It is to prevent the situation you said. After thirty or fifty years and after this new standard has been deeply rooted in the hearts of the people, the court will gradually find ways to promote it. At that time, will there be any opposition voices?"

"Master is very good!" Li Zhi raised his thumb and flattered him slightly, but soon, we turned our attention to another more urgent topic. "Brother Jun, I can't wait to go play in the dog cart." Li Zhi looked at the sparse snowflakes outside the window and sighed.

"That's called a sled, not a dog cart!" I was so angry that I almost wanted to use my hand to slap Li Zhi, and then glanced at the princes who had been thinking about going out of the wild all day long: "What's the panic? How thick is the snow now? At this time, you go and pull a sled. It would be strange if you don't mess up your butt. Look at this snow method, I'm afraid I'll have to wait for a day or two. Well, at that time, as long as you can have a heavy snow, my master will take you out of the city wilderness with you, but one person can only do one round! There are few cars and many people, so it's not enough to sit and play more."

As soon as these words were spoken, the four little kids almost jumped up and screamed. Li Zhi was wrenching his fingers on the side, and I leaned forward: "What's wrong, what are you planning?"

Li Zhi laughed dryly: "It's nothing, I just calculated how many sleds I can get there." As soon as I heard this, I knew that it must be the girl Li Shu. "You little brat, don't tell me tomorrow, and you are going to find your seventeenth sister again in private?" I patted Li Zhi's shoulder and cursed.

Li Zhi yelled: "There's no way, Brother Jun, you said that sleds are so fun? You have so many doors. I'm afraid I won't be able to grab one at that time. So, after gritting my teeth, I made three, but the number of dogs on the ground pulling the car is probably a little less."

I curled my lips and said, "You can just get some from your father, too?"

Li Zhi glared at me hatefully: "You can say it out loud. Just for thirty good dogs, I have let my father nag for a long time, and there is no courage. I can't help but think about it myself. However, I finally got nearly forty dogs and prepared to build a sled so that these younger brothers can have fun together. It will also prevent your brother from saying that I am right to take up your land all day long."

"Tsk, don't say such things. I'm really angry when you say it. Who took the high-power telescope I put at home last time?!" I glared at Li Zhi and said angrily.

Li Zhi immediately surrendered and quickly smiled and said, "Brother Jun, you are so incredible. I told my sister at that time that I would borrow it for two days."

"Two days?" I stretched out two fingers that were almost as thick as a carrot and wandered under Li Zhi's nose. He spitted on Li Zhi's face hard: "Two months have passed, where is the thing? Even if I look at it every day, I will finally be satisfied after watching it for two months, right?"

Li Zhi's expression suddenly seemed very heavy, and his tone seemed very ashamed: "Brother Jun, I'm sorry..."

———————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

When I saw Li Zhi's expression, I suddenly felt a bell in my heart. I was so familiar with this expression. "What are you doing again? You kid wouldn't say that the thing I lent to you was broken by your wife? I heard this excuse and my ears were calloused. Brother, let's think about it, it's better to change to some fresh tricks!" I looked at this girl pretending to be a ghost in front of me, and I was so angry that this guy treated me as a rich gold mine. He was the rogue proletarian who specialized in defeating the landlords and old wealth.

"Ah! Brother Jun, how did you know that it was not my wife who did it?" Li Zhi's expression seemed shocked and admired, as if I was the entertainment reporter who was waiting in front of his thatched house. After hearing this, I felt cold and rushed upwards with anger. I squeezed Li Zhi in front of him, and his shiny front teeth were lit in front of Li Zhi: "What are you playing with? What's wrong with my things?"

"I broke my son..." Li Zhi buried his head and confessed his guilt, and I was so angry that he was so angry: "What! I said Xiao Zhi, you have grown up, why are you making up a reason? Use your son as a scapegoat? Tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk t

Li Zhi's eldest son was born, and Uncle Li named him Li Zhong, a boy weighing eight pounds, Li Zhi was extremely precious. But at the moment, Li Zhi seemed to be scoundrel, and the fence-bearing grass squeezed out a sad look: "It's not my wife Qin Qin. When I was not at home, I used that thing to play with the child, but who would have thought that this kid would just hold him and let go..."

"Okay! Stop talking, if you continue, I'm afraid I can't help but slap you twice! That's what I finally got. You, you Li Zhi, don't say anything. Now, I can only repay the debt to my father!" I sighed. I can't just jump into Li Zhi's house and grab the crown prince and beat him up? Li Zhi's mouth is also a protector, and it would be strange if he doesn't turn against me.

Li Zhi slapped Bangbang in his chest: "Don't worry, Brother Jun, I am the prince after all, and I will definitely pay it. But now I don't have money in my pocket, so I might as well send it to you another day. Hehe, Brother Jun, how much do you think you will pay?"

"One Thousand Guan!" I stretched out a finger and gritted my teeth viciously. Although I spent ten Guans to buy and grab the land from the Wuhan Institute of Research and Research, I can't be more suitable for this thing, Li Zhi, a bastard who needs to be beaten.

Li Zhi exclaimed, "One Thousand Guans! I said, Brother Jun, why don't you rob me?" I grinned fiercely, "That's right! I rob you, don't forget, last time you took a pair of dragon and phoenix auspicious bottles, and you took two hundred Guans. Do you really treat me as a beggar?!" When I think of this, I was brave enough to be born from the side, and I wish I could hold this guy's heart! You are the one who is the ancestor, and Uncle Li's bloodline has been completely inherited by this fence...
