"Chai Meng, you go and get two sabers from our army, I want to take a look." Sun Ce ordered.

"Yes!" Chai Meng nodded, and took two sabers from the barracks to Sun Ce. Sun Ce took it, held the two sabers in each hand, and then suddenly exerted force, causing the two swords to collide.

Of course, Sun Ce didn't use all his strength, that is, according to the strength of a normal soldier when he slashed, only after hearing the sound of "dang", a gap appeared on each of the two sabers.

Sun Ce didn't seem to be satisfied, and collided again, it was still a gap to a gap, and the two gaps became bigger after a second collision.

Third ......

Fourth ......

……

Until the seventh time, both sabers shattered at the same time.

"It's still too fragile!" Sun Ce shook his head. You can only slash seven times, you know, the saber is the weapon that the knife soldier relies on to survive, how can it be so vulnerable?

"Come with me to the blacksmith!" Sun Ce thought for a moment, and then stepped out of the courtyard.

After coming to the blacksmith shop, Sun Ce found a blacksmith. The blacksmith's name is He Yuan, who has been playing iron for more than ten years, and is an old blacksmith.

"Master He, I came to ask you, is our army's saber made of steel, that is, refined iron?" Sun Ce asked.

"It's not!" He Yuan shook his head, "Most of our army's sabers are made of pig iron, if we use fine iron, our army does not have so much fine iron, not to mention, the construction period is still very long, and the cost is not ordinarily high." ”

"I see!" Sun Ce suddenly realized that pig iron was brittle, so it was so easy to be cut.

"Is the current steelmaking method just a repeated beating?" Sun Ce asked with a frown.

"Not bad!" He Yuan was a little puzzled, wasn't this something he asked knowingly?

"I have a way to solve the problem of less and cumbersome tapping!" Sun Ce said, "The pig iron is heated into semi-liquid and liquid form, and then iron ore powder is added, and at the same time, it is constantly stirred to use iron ore powder and oxygen in the air to remove part of the carbon in the pig iron, so that the carbon content in the pig iron is reduced, and the slag is removed, and the steel is directly obtained, which is the steel frying technology." ”

"This ......" He Yuan listened to Sun Ce's words in disbelief, this is impossible, right? His heart was full of doubts, if it was so simple to be able to produce steel, how could the ancestor not find such a method? The ancestors have all said, "100 tempered into steel", can this be fake?

"Of course, you may not understand or believe it, but give it a try, just in case it succeeds!" Sun Ce smiled slightly.

"Okay!" Who made Sun Ce the lord? Even if He Yuan didn't think that this could succeed in his heart, he still tried according to Sun Ce's requirements.

According to Sun Ce, He Yuan built a simple blast furnace with corundum, silica sand and other high-temperature resistant materials, and then used the reciprocating bellows to provide enough wind power, according to Sun Ce's words, this can greatly improve work efficiency!

The rest, it's up to you to fry!

Sun Ce smiled very confidently, this is sure to be able to produce molten steel!

According to Sun Ce's instructions, the first furnace of molten iron was quickly smelted, and He Yuan and his apprentices immediately added the iron ore powder that Sun Ce said to it, and then began to stir continuously, and when Sun Ce said to stop, they stopped, and then poured out the "molten iron" in that furnace.

"Iron! It's really fine iron!! He Yuan saw the molten steel poured out of the furnace and shouted in surprise, "Quick, don't let the fine iron condense, process it now!" ”

He Yuan couldn't believe that he had obtained Jingtie so easily, and immediately knelt down in front of Sun Ce: "Lord, He Yuan is convinced!" ”

"Hurry up, hurry up, what is this, this method is also something I thought of by accident, and I don't know if it's feasible." Sun Ce smiled slightly, "The rest of the matter will be handed over to you, you must build a sword, gun and halberd for me as soon as possible!" ”

"Yes!"

"By the way, how long does it take to build 10,000 sabers normally?" Sun Ce asked.

"Ten thousand ......" He Yuan frowned, "Our blacksmith shop now has fifty craftsmen who can make iron, if everyone keeps making iron, they can make one or two sabers a day, and it will be two thousand a month, if it is ten thousand ......" Speaking of this, He Yuan was a little embarrassed, as if it would take five months to complete, and if it was to build something else, it would take even longer!

"Can one man build two in a day?" Sun Ce frowned, "Master He, do you think you can operate like this, let him only make the handle every day, let him only build the blade every day, let him only sharpen the blade every day, let him only be responsible for assembling the blade and the handle every day, the four of them form an assembly line, can they complete more manufacturing every day?" ”

"This ......" Master He thought for a moment, nodded, and shook his head again, "Theoretically it is possible, but in practice it is not!" ”

"Why is that?" Sun Ce was puzzled.

"It's because now each master's skills are different, if you do this, there will inevitably be a lot of mismatch in individual sizes, and when the time comes, the bad ash will make a lot of waste products." He Yuan thought for a while and said.

"No, no, no." Sun Ce shook his head, "The premise I said is that every master has a size standard in his hand, and every master does it according to that standard, is this okay?" ”

"Yes! Absolutely! He Yuandaxi, "Why didn't I think of it?" The lord is really talented! ”

"Well, you should unify the weights and measures in the hands of all the masters in the blacksmith shop as soon as possible, and we will produce them according to the same size!" Sun Ce instructed, "When you are reunified, come to my house, I have something to explain." ”

"Yes!" He Yuan can now imagine the production speed after the uniform size and then the assembly line, and he can't help but be very excited.

"My lord, this is the unified weights and measures?" On the way back, Chai Meng asked.

"That's right, in fact, there is nothing wrong with Qin Shi Huang, there are only benefits to unifying weights and measures, and there is no harm! Otherwise, the north and the south use different weights and measures to trade, I say this is half a catty, but you say this is eight taels, how can this work? Sun Ce smiled slightly, "It's just that Qin Shi Huang made one of the most important mistakes was to be too violent, and he implemented a policy with pure violence, in exchange for pure violent resistance, and the result of this rebellion is that more and more people will think that this policy is wrong!" Sun Ce said, "Sometimes, it's not right to only have wrists and not know how to be flexible!" ”

Chai Meng followed behind Sun Ce, listened to Sun Ce's words, and nodded thoughtfully.
