But it seems that no matter whether Xiao Han believes it or not, anyway, the craftsmen believe it, Chai Shao's words, even the guards at the door are flushed with excitement, Xiao Han even doubted, issued them a knife, let them assassinate Xue Ju now They will rush out without hesitation, and the spiritual strength is really huge......

Dressed in military uniform, the heroic spirit splashed everywhere...... Xiao Lizi took the heavy horseshoe from the trembling hand of the old blacksmith, the color was shining, the shape was regular, the sound of knocking was crisp and curling, it was indeed a good piece of steel!

"With this steel, and can you make a blade with this method?" Xiao Lizi looked eagerly at the old blacksmith and Xiao Han.

In fact, I don't complain that Xiao Li is so fancy, as the commander of the first army, the situation in this military camp is naturally extremely familiar! Now there is a shortage of weapons in the barracks, and the quality is far from the same, what he holds in his hand is a sword made of a hundred refined steel, and the blade of ordinary soldiers does not even have ten refinements, and it is even more common to break on the battlefield, if they can mass-produce high-quality standard equipment, then the improvement of the army's combat power is no less than the invention of the horseshoe!

"Back to Your Highness!" The old blacksmith also pointed to the iron furnace behind him excitedly, and said: "It's completely possible, the steel refined by the method of Chief Manager Xiao can be made into a blade, even if its quality is not as good as a hundred steels, the difference must not be too far!" ”

"Hundred Steel...... Xiao Li Zi closed his eyes and was silent, but his slightly trembling hand indicated how uncalm his mood was at this time......

"You ......"

Xiao Han looked at these two people, and at this time suddenly realized that it was not only the rapid manufacture of horseshoe that people valued, but also other uses!

However, this group of dirt buns, this kind of thing that can just be called steel, is also regarded as a treasure, if I tell you that as long as you improve this blowing device, so that the air volume is larger and more stable, supplemented by phosphorus and other things, the weapons made to cut your so-called hundred steel and play, wouldn't you faint? Cut!

If you want to talk about people, you can't be too happy, Xue Shu has stood at the end since he came in, and he is calm by nature, so he has to look carefully.

Xiao Han's expression was deeply imprinted into his eyes from the beginning of the understanding to the later disdain, and Xiao Han had such an expression, does this mean that he still has something good to come up with?

So Xue Shui asked tentatively: "Brother Xiao, are you dissatisfied with this?" Is there a better way? ”

Xiao Han was in a good mood at this time, and when he heard this, he didn't even think about it, and Niu Hide blurted out: "That's natural, as long as I make a slight change, the steel will definitely be better than your hundred steel!" If it weren't for the fact that these iron ore iron ingots were not right, it would not be impossible to create a few divine weapons! ”

"Is that true?!"

As soon as Xiao Han's words came out, he saw that the people in the whole courtyard were looking at him like monsters, and he suddenly screamed in his heart, how could this mouth say what was in his heart again?! This is the skill he is going to pass on again, why is he going to say it now?!

"No... That's right..."

But now, looking at the group of hungry wolf-like people around him, Xiao Han can only stubbornly decide, forget it, he bragged about it, and he had to finish killing him...

It's over, it's blown up again, why are the Tang people so uncomposed?

Xiao Han was still thinking about improving it tomorrow, but unfortunately Yuan Shao and the old blacksmith were not good things, and they were all anxious and hungry wolves, urging him to do it one after another, and even used the method of agitation.

Looking at the reddened eyes of a yard, helpless, Xiao Han had to give everything he knew for his own safety.

Chai Shao and Xiao Lizi, who were happy with a clever trick after inadvertently asking one more question, naturally couldn't help but be overjoyed, and immediately found a few carpenter masters and carried a pile of wood by the way.

Under the command of Mr. Xiao, a double-outlet bellows was freshly baked, Xiao Lizi curiously stepped forward and pulled the handle, while the old blacksmith put the back of his hand on the air outlet, feeling the air outlet continue to spit out bursts of cool breeze with the movement of the handle, and constantly nodding in surprise.

In the eyes of a professional like him, Mr. Xiao's new bellows not only has a large air output, but also spits out wind no matter whether it is pushed or pulled! In this way, one furnace is connected to two bellows, which can ensure that the wind power is continuously transmitted in, and the stability of the furnace fire can be guaranteed!

If the previous methods were all simple ideas, then this bellows can be regarded as a complex machine, looking at the master carpenter looking at Xiao Han with awe, even Xue Shui couldn't help but hold Xiao Han's head and look left and right, looking at that look, he couldn't wait to open it to see what was inside!

"Let it all go! The head is going to be ripped off! ”

Poor Xiao Han tried hard to pull his head out of Xue Shui's clutches, and hid to the side with his head in his hands, so that he wouldn't tell them that this was going to the rural classmates to help the autumn harvest and experience life by the way, watching this bellows be fun and secretly dismantling it for others to see the structure, although he didn't settle it in the end......

"Hahaha......" Chai Shao and Xue Jing laughed in unison when they saw Xiao Han rubbing his head, they came to see the progress of the project, but they accidentally found such good news, how could they not be happy?

And Li Shimin, who was smiling silently on the side, suddenly remembered that since Xiao Han appeared, the good news was simply one after another! If the horseshoe is a flash of inspiration, then the formula for steelmaking, and the complicated blowing mechanism, cannot be explained by cleverness!

In this stormy time, could it be that God sent him to me on purpose? Looking at Xiao Han, who was laughing with them, Xiao Lizi suddenly had a feeling in his heart that he must hold it in his hands! It felt like a seed that had taken root in his heart ever since!

The bellows are there, and the materials are almost complete, so if you don't make a sample, it is estimated that no one here will be able to sleep well tonight!

Pour all the coal in the rattan frame into the furnace, all the apprentices are retired, only the master can get started, even the work of pulling the bellows was robbed by Chai Shao, pushing and pulling like a bear child who found a new toy, and he did it energetically!

After a while, a furnace of molten steel boiled out again, and three or four long knives were poured in one go, and this time Xiao Han specially looked for the phosphorus powder that Chai Shao wanted, which is usually added when setting fire in the army, so it was easy to find a jar, and in order to maintain toughness, more toner was added.

When the molten steel cooled, the four long knives were placed on the board one by one, but the long knives were not shining with cold light as imagined, but the shape was mottled and strange, looking at the disappointed expressions of several people, the old blacksmith smiled happily.

"It's okay, it's okay, don't look at it now, as long as you polish it, it will be a good knife!"

"Oh?" Everyone was relieved and hurriedly urged the old blacksmith to polish!

The old blacksmith is not pretentious, he took a handle, poured water on the whetstone brought by the apprentices and began to polish, a pair of thick arms is definitely a true manifestation of strength and beauty, even the friction between the knife and the grinding stone "rubbing" is very rhythmic! The old blacksmith did it quickly, and it didn't take long for a steel knife to appear.

The steel knife was sharpened, but the old blacksmith did not stop, and then the sharpened knife was directly stuffed into the furnace to heat, and after the knife body was completely burned red, the old blacksmith carefully used iron pliers to cut the knife out, and the dragonfly pointed the tip of the knife into the water.

"It turns out that this is quenching...... Xiao Han stared at this scene curiously with wide eyes on the side, "It's not said in the novel that quenching requires nine days of cold water or something, why can you just use this ordinary water here?" Or quench the blade first, and on the back of the quenching knife, it looks quite exquisite......"

However, although he had doubts in his heart, in order to maintain his master's demeanor, Xiao Han didn't ask after all, anyway, he would always know in the future......

The quenched steel knife is not very beautiful, and even in Xiao Han's opinion, it does not meet the mechanical standards at all, the front and back are the same wide, the arc is too large, although the blade is snow-white, but there are still some small pits the size of millet grains when you look closely, this is the bubble in the molten steel, Xiao Han has no good way to do it now.

But even so, it was a rare good knife in their hands! Especially the old blacksmith, holding a steel knife in his hand, has mixed tastes in his heart, although under the more complex process, he can make weapons far beyond it, but such materials are all hard to find in the world, and he can't beat a few in his life, and according to the method taught by Xiao Han, how many people can fight in a day? Dozens? Or hundreds? Even if the whole army has one hand, it is not impossible!

Li Shimin and Chai Shao also looked at this seemingly ordinary long knife with warm eyes, and they almost didn't come up to grab it!

"What's next?"

"Try the knife..."Xiao Han rolled his eyes, to be honest, this knife may not even be able to catch up with the quality of Wang Mazi's kitchen knife in later generations, but thinking that it is more than 1,300 years ago, I am relieved.

"Where can I try my knife?" Chai Shao took the long knife and swept it through the crowd with a pair of big eyes, so frightened that Xiao Han hurriedly took a step back, I heard that Japan would pervert people to test the knife, wouldn't he do the same......

Of course, Xiao Han's worries were superfluous, Chai Shao looked around and saw a bowl-thick locust tree in the corner of the wall, and he was immediately happy, just let it be!

The dragon walked and walked tiger, carrying a knife like an executioner to the corner of the wall, the chief manager of Chai stood in front of the tree, standing still luck, and then shouted loudly, the long knife in his hand was like a white light, and he slashed towards the tree, I don't know if Chai Shao did it on purpose, the tip of the knife accidentally cut through the courtyard wall next to it when he was chopping, and sent out a spark, and then slashed heavily into the tree with sparks!

"Good knives!" Everyone cheered in unison!

Looking at Chai Shao again, the long knife was deep in the trunk of the tree, and it was almost cut off at the waist of the tree!

Chai Shao let go of the hand holding the knife, and the blade of the knife immediately shook up and down like a spring plate, and the big tree with the thickness of a small pot also trembled slightly, as if it would break at any time!

Spit on his hand, Chai Shao pulled out the long knife with force, raised it in front of him, and looked at the sun, the blade was intact! This kind of quality definitely surpasses the vast majority of blades now!

"Good, good!"

When Li Shimin, who was standing behind, saw it, he immediately applauded: "Brother Xiao is really a genius, no matter medicine, miscellaneous science, or smelting, he has such attainments, and when I play my father, my father will definitely reward Brother Xiao greatly!" ”

"Reward?" When Xiao Han heard this, his originally reluctant thoughts immediately came to life, and his mouth opened widely: "Carving insect skills, carving insect skills, it's not worth mentioning, hahahahahaha......"

"Oh, Brother Xiao looks down on fame and fortune so much, I admire it, so forget it......"

"Gaga...... Hey, don't, don't really forget it! I'm just polite, I haven't married a daughter-in-law yet! How much to give! ”
