"Can you divide it so finely? Is that what these things are doing? Li Zhi picked up the pointer floating on his face with his finger and asked casually. That is, you look at these things, the error between them is definitely less than a millimeter, why? It is to enable these things to be mass-produced, to be able to carry out large-scale and streamlined production. Take something as an analogy, let's just say that all the steel crossbows in our Datang army now, you should have seen them, right? You know? Nowadays, there are nearly 10,000 steel crossbows used by the Datang army, and if any one of them has a problem, you can choose one from the other 9,999 steel crossbows and replace the damaged parts! Cow, right? I raised my eyebrows triumphantly, but unfortunately, a stupid guy with an unenlightened head next to me came up with a sentence that made me half angry.

"Isn't this man sick? Pick another handful, you can't use it! It was Uncle Li's youngest son who said this, Li Ming, a nine-year-old little kid who had not yet been crowned king, and after this chubby little guy said this, he tilted his head proudly. Li Jian, the acting king on the side, and Li Fule, the king of Zhao, grinned straight and laughed, and Li Zhi scooped up Li Ming with tears and laughter, let this guy sit on his lap, and slapped this little guy's fat buttocks: "Stinky boy, don't talk nonsense to me, Shizun is asking questions." ”

Li Shen ignored Li Ming, his eyes were very bright, and he immediately realized an extremely important fact. "Brother Jun, do you mean that all the equipment of the Martial Arts Research Institute, if a part is damaged, can be repaired with the same part at any time?"

"That's right, that's the truth." I smiled and nodded, don't talk about Li Shen now, Li Zhi also furrowed his eyebrows with a serious expression: "Brother Jun, you're not joking, are you?" Even if it's a big guy like the artillery of the Martial Arts Research Institute, can it be replaced like this? ”

I smiled confidently and bowed slightly. "Obediently, if all of my Datang's ordnance is supplied by the Martial Arts Research Institute, then I don't know how much money I can save every year in Datang." Li Zhi gasped.

He is indeed right, Datang is indeed rich, but it is not rich enough to squander the people's taxes at will, and in this era, to maintain the cost of nearly 500,000 troops, it is not a small amount, Datang's bows and crossbows and various ordnance are often damaged by a certain part, and the large siege equipment worth several or even hundreds of times becomes a pile of waste, otherwise, it has to be reforged as it is before it can be repaired, the time spent and the money spent, sometimes it is even better to discard it directly, After the Armed Forces Research Institute re-established the weights and measures, whether it was a heavy firearm weighing 1,000 catties such as artillery, or a light long-range weapon with a total weight of no more than two catties, such as the assassinator crossbow used by the Wu Ben army.

---------------------------------------------------- the maximum error of all the parts in between, it was already the maximum accuracy that the craftsmen of this era could achieve, and it was because of this that the assembly line and standardized production could be realized.

"I'll tell you, that's the benefit of refining and refining weights and measures, you know?" I laughed. Li Zhi nodded, but Xuan Ji asked me a little uneasily: "Brother Jun, if this is the case, then all the weights and measures in my Datang will be lost?" ”

I glanced at Li Zhi: "Xiaozhi, this is what you don't understand, tell you, why this kind of accurate weights and measures are only used in the Ministry of Industry and the Martial Arts Research Institute, do you know?" It's just to prevent the kind of thing you are talking about from happening. After thirty or fifty years, after this new standard has been deeply rooted in the hearts of the people, the court is successively trying to find ways to promote it, at that time, will there be any opposition? ”

"Master Gao Jianye!" Li Zhi gave a thumbs up and patted his ass slightly, but soon, we turned our attention to another, more pressing topic. "Brother Jun, when will I be able to play with the dog car, I can't wait." Li Zhi looked at the sparse snowflakes outside the window and sighed vigorously.

"That's called a sled, not a dog cart!" I was so angry that I almost wanted to whip Li Zhi with my hand, and then glanced at the princes who had been trying to go out all day long: "What are you panicking about?" How thick is this snow now? At this time, you go to sit on the dog sled, don't turn your ass and eggs upside down, look at this snow method, I'm afraid you have to wait a day or two, well, when the time comes, as long as there is a heavy snow, the teacher will take you out of the city together, but one person can only do one round! There are fewer cars and more people, and it is not enough to sit and play more. ”

As soon as these words came out, the four little children almost jumped up and screamed, and Li Zhi was wrenching his fingers on the side, and I stepped forward: "What's the matter, what are you calculating?" ”

Li Zhigan laughed twice: "It's nothing, I just calculated how many sleds I could make there." "As soon as I heard this, I knew that it must have been done by this girl Li Shu." Stinky boy, Mingli didn't tell me, but went to find your seventeenth sister again in private? I patted Li Zhi on the shoulder and scolded with a smile.

Li Zhi said twice: "No way, who asked Brother Jun to tell you how fun the sleds are, you have so many mouths, I'm afraid I won't be able to grab one at that time, no, I gritted my teeth, I also made three, but the number of dogs pulling the cart is a little less." ”

I pouted and said, "You can also get some from your father?" ”

Li Zhi glared at me hatefully: "You can say it, just for thirty good dogs, I can let my father nag for many days, how can I still have that guts, no way, I can only think of my own tricks, but finally let me get together nearly forty dogs, ready to build another sled, so that these younger brothers can also have fun together." It also saves you from saying that I take advantage of you. ”

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

Li Zhi immediately relented, and hurriedly smiled: "Brother Jun, what you said is too much, I told my sister at that time, I borrowed it to play for two days." ”

"Two days?" I stretched out two fingers that were almost the thickness of a carrot and dangled under Li Zhi's eyelids, and spittle Xingzi sprayed vigorously on Li Zhi's face: "Two months have passed, what about things?" Even if you watch and play every day, it's finally enjoyable after watching it for two months, right? ”

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

As soon as ---------------------------------------------------- saw Li Zhi's expression, my heart suddenly became alarmed, and I was too familiar with this expression. "What are you doing again, shouldn't you kid say that the things I lent you were broken by your mother-in-law again? I've heard this excuse so much that my ears are calloused, brother, think about it, it's better to change something new! "I saw this girl pretending to be a ghost in front of me, and I couldn't get angry, this guy simply regarded me as a rich gold mine, and he was the lumpenproletarian who specialized in bringing down the landlord's old wealth.

"Ahh Brother Jun, how do you know that it wasn't my daughter-in-law who did it? Li Zhi's expression was shocked and admired, as if I was the entertainer who was waiting on the edge of his thatched house. Hearing this, my heart was cold, and I rushed up angrily, squeezing Li Zhi in front of him, and a mouthful of snowy front teeth were all shining in front of Li Zhi's eyes: "What kind of treasure are you kid playing!" What's wrong with my stuff?! ”

"Let my son break ......" Li Zhi buried his head in the confession, and the angry Lao Tzu was happy: "What! I said Xiaozhi, you can grow up, why is it not good to make up your son as a scapegoat? Tsk tsk, have you as a father? Besides, your son has only been on the full moon for a few days, can he hold a telescope to look at the stars and the moon? ”

Li Zhi's eldest son was born, and Uncle Li named him Li Zhong, an eight-pound boy, Li Zhi's baby is very good. But right now, Li Zhi looks like he is going to be a scoundrel to the end, and he saw that the grass on the wall squeezed out a sad look on his face: "It's not my family's son, take advantage of my absence at home, take that thing to tease the child, but who would have thought that this kid would let go of it after holding it twice......"

"Gotcha! Don't say it, if you keep talking, I'm afraid I can't help but slap you twice! That's what I got with great difficulty, you, you, you, you Li Zhi, don't say anything, and now, you can only pay the debt to your father! "I sighed, I can't go to Li Zhi's house and pick up the imperial grandson and beat him violently, right? Li Zhi's son Zhen Zhen is also a calf protector, so it's strange if he doesn't turn his face against me.

Li Zhi's chest slapped Bangbang: "Brother Jun, don't worry, I am also a prince when I am young, and I will definitely pay for it, but now I have no money in my pocket, why don't I change it to send it to you, hehe, Brother Jun, how much do you say you will lose?" ”

"A thousand kans!" I stretched out a finger and gritted my teeth viciously, although it took me ten times to get it home from the Martial Arts Research Institute, but we can't favor Li Zhi, the underwhelmed bastard.

Li Zhi exclaimed: "A thousand runs! I said, Brother Jun, why don't you go and grab it. I smirked wickedly, "That's right! I'll rob you, don't forget, last time you took a pair of dragon and phoenix Chengxiang vases from my son, and you took two hundred yuan, you really treat my master as a child? ! "As soon as I think of this, I have the courage to come from the side, and I can't wait to think of this guy's heart! Ancestors, you are a plank, Uncle Li's bloodline has really been inherited by this wall grass very thoroughly......
