Lin Hai then introduced: "Lord Yuan, they are the best blacksmiths in my Ministry of Industry, they are three brothers, the one with the most beard is the eldest Nanmen Tie, the tallest is the second Nanmen Yang, and the most burly is the third Nanmen Xing." ”

After speaking, he said to the three brothers of the Nanmen family: "This is Lord Yuan Fangyuan, the director of the military hospital, and he is also the general of the Eastern Expedition, and you still don't salute." ”

The faces of the three brothers of Nanmen changed greatly when they heard this, but they didn't expect that this unattractive guy in front of them turned out to be the legendary female soldier's brother-in-law, the real one of the empire, and hurriedly bowed and saluted: "Xiaguan has seen Lord Yuan." "The reason why I use the subordinate official to claim to be because the errand workers in the Ministry of Industry have official positions, although it is only the kind of official position that does not enter the stream.

Yuan Fang admired the talent the most, stepped forward to help the three brothers of the Nanmen family, and said with a smile: "This time I am here to find a few helpers, I hope the three of them will not refuse." ”

The boss Nanmen Tie patted his chest and said, "Don't worry, as long as you can do it, you will never say anything." ”

Yuan Fang patted Nanmen Tie's shoulder, and beckoned to the blacksmiths of the dozen or so chambers of commerce who followed behind him, "You guys come over to meet the three masters." Known as the master, the three brothers of Nanmen blushed a little, and hurriedly waved their hands and didn't dare to say it.

Everyone saw the ceremony, Yuan Fang took out the drawings and explained again, this time, Yuan Fang spoke more carefully, some indescribable places also used the waste and branches piled up next to a simple model, after making sure that everyone understood their requirements, Yuan Fang clapped his hands and said: "Okay, the drawings should everyone understand, I said my requirements, the outermost layer of the iron roll should be at least one centimeter, uh, almost a knuckle thick steel plate or fine iron, it must be round, and the left and right outer sections of the inner layer should also be made of good materials, As for the counterweight inside, there are no special requirements, but it must be reliable, the weight, this, about two tons, and special attention should be paid to the surface of the wheels must be smooth, preferably deep polished, by the way, and this shelf and steering device, all of which must be made of the best materials. ”

Nanmen Yang was more careful, pointed to the two iron rolls on a baffle-like thing and asked, "Lord Yuan, what is this thing for?" ”

Yuan Fang explained: "This is used for sprinkling water, seeing that this trough is not there, and it is filled with clean water, the water will leak out from the row of small holes below and sprinkle on the iron roller to cool down." Nanmen Yang nodded suddenly, secretly admiring Yuan Fang for coming up with such an exquisite and concise design.

Nanmen Xing asked curiously: "Lord Yuan, what is this thing you designed for?" ”

Nanmen Tie's face changed slightly, and he hurriedly scolded: "Third child, don't ask questions if you shouldn't ask." Nanmen Xing stuck out his tongue, this action was originally a very cute expression, but it looked a little weird on the face of such a big guy and three thick.

Yuan Fang smiled and waved his hand and said, "It's okay, this thing is not a secret, in fact, it is just a tool to pave the way." ”

Nanmen Tie was surprised and said, "Paving the road? All the blacksmiths, including Lin Hai, who was listening to the side, were very puzzled, they couldn't understand when it was time to pave such a big thing as a road, and it couldn't be done by a few stonemasons.

Yuan Fang looked left and right, squatted down and scraped some soil on the ground with his hands, broke a small piece of smooth branches, and said: "I have a new paving material, which is particularly viscous when softened, and must be compacted before solidifying, just like this." As he spoke, he sprinkled the soil on the ground, and then used the branches of the tree to roll over the floating soil, and suddenly the original floating soil became solid and smooth.

Nanmen Tie suddenly realized, and praised again and again, although he didn't know what material Yuan Fang said, but this idea was really good, but it was a bit overkill.

Yuan Fang continued: "In addition to the two iron rollers, the most important thing is the bearing, you have no problem in this regard, right?" ”

Nanmen Yang patted his chest and said: "We are good at this, you can rest assured, even the pine is not as good as us, but Lord Yuan, such a big iron roll, welding is probably not reliable enough, or let's use the mold to pour, this thing is not very worn, a molding pouring should be enough to deal with, what do you think?" ”

Yuan Fang waved his hand and said, "How do you do it yourself, welding?" Do you know how to weld? ”

Nanmen Tie glared at Nanmen Yang, and explained with some embarrassment: "Lord Yuan, we know a little bit about welding, but we are still trying to explore the stage, and we are not yet mature, and the second brother is a little Meng Lang." ”

Yuan Fang became interested when he heard this, welding, this is a problem that he has always wanted to solve and is difficult to solve, if these guys in front of him have a way, it will help a lot: "It's okay, you tell me, what stage has it progressed to?" ”

Nanmen Tie glanced at Yuan Fang, and really couldn't understand why the director of this military hospital was so interested in these things, looking more dutiful than the main hall of the Ministry of Industry, he wondered, and Nanmen Tie didn't hide it, and took out a white stone from the small room next to him and said: "Lord Yuan, we just got this thing, it will produce a flammable gas when it encounters water, which can theoretically support combustion." ”

Without waiting for Nanmen Tie to finish, Yuan Fang waved his hand to interrupt, took the white stone and looked at it carefully, got some water from the sink and poured it on it, with a bang, a puff of smoke rose, Yuan Fang sniffed, and asked Sang Rou to get the charcoal over, and sure enough, the stone bubbling in the water was ignited at once.

Yuan Fang stood up, lifted some soil with his feet to extinguish the white stones and flames, looked at Nanmen Tie and said, "Where did you find this thing?" ”

Nanmen Tie looked at Yuan Fang a little inexplicably, and only replied after a while: "It's not found, how can I say it, this thing is something we found occasionally, it's not natural, we use many kinds of stones to grind it into powder and then burn it." ”

Yuan Fang didn't ask in detail, and the conversation changed: "Does anyone else know the formula except you?" Nanmen Tie and the two brothers glanced at each other and shook their heads in unison.

Yuan Fang secretly breathed a sigh of relief, ecstatic in his heart, gave Yu Jingqiu a look, and then said to Lin Hai: "Lord Lin, I have something very important to take the three of them into the palace, so I won't stay long, I will take the three of them first, I also hope that Lord Lin will keep this matter as secret as possible, as for what the specific matter, Your Majesty will send someone to inform you." ”

Lin Hai watched blankly as the four female soldiers and officers beside Yuan Fang surrounded the three brothers of the Nanmen family, his heart tightened, and he thought that they had committed something, but when he thought about it, he felt that it was wrong, and he was about to ask, when he saw Yuan Fang's extremely serious expression, he swallowed back the doubts that were about to be exported.
