Yang Jia looked around the crowd and found an older craftsman, pointed to the old craftsman and said, "Come and take a look at this iron pulp." ”

The old craftsman who was pointed out by Yang Jia thought that Yang Jia had made a mistake in smelting iron ore and wanted to punish himself. didn't dare to take a step forward, knelt down on the spot and kowtowed to beg for mercy: "Official! The villain is wrong, I must speed up the forging, official...... I was wrong! ”

Yang Jia reluctantly walked over to help the frightened old craftsman, and explained that he didn't mean to punish everyone. Hearing Yang Jia's assurance, the old craftsman followed Yang Jia tremblingly to the side of the 'furnace', Yang Jia pointed to the iron slurry derived from the 'furnace', "These small pieces of iron in the iron slurry that have not been completely melted will affect the quality of the cast weapons!" When the old craftsman heard this, he was still looking for his own mistakes, and hurriedly explained that those small pieces of iron could not be burned at all, and that those pieces of iron had always existed since he built his own weapons, and even the best craftsmen in the Punch Jin could not burn them completely. Yang Jia smiled helplessly when he heard this, didn't I know this situation, didn't I hear that I called you over to solve this problem?

Yang Jia pointed to the mouth of adding charcoal fire to the 'furnace' and said, "Then do you know why you can't burn those small pieces of iron?" The old craftsman shook his head blankly,

"That's because the temperature of the charcoal fire is not enough to fully reach the melting point of iron!"

"Wen what? What is iron? The old craftsman asked, still shaking his head.

Yang Jia had no choice but to rub his forehead helplessly and said: "In short, the charcoal fire is not strong enough, do you understand?" ”

It was obvious that Yang Jia was talking about chickens and ducks, but the old craftsman was still puzzled and asked: "It's already very prosperous, and when we burned iron, we also sent someone to fan the big pu fan at the mouth of the charcoal fire." ”

Yang Jia was finally defeated by the old craftsman, and pulled the old craftsman and said: "Take the pu fan, but you still can't let the charcoal fire burn the most." You can help me make something that will make the charcoal fire burn the most vigorously, and it will also make these little pieces of iron that can't burn melt. After speaking, Yang Jia pulled the old craftsman to squat on the ground and drew the structural diagram of the 'bellows'.

That's right, it's 'bellows', Yang Jia really didn't expect that 'bellows', a tool with a simple structure and strong and durable, had not been invented by the time of the two Jin Dynasty! When he first came to the 'furnace', Yang Jia found that there was no blower equipment at the mouth of the charcoal fire, which is why Yang Jia shook his head.

After Yang Jia explained the working principle and structure diagram of the 'bellows', he clapped his hands and said: "This 'furnace' has stopped first, you first make this 'bellows' as I said, as long as the 'bellows' come out of those small iron pieces that cannot be burned, it is guaranteed to be melted." ”

Yang Jia felt that what he said was impassioned and inspiring. But the craftsmen around him just sighed indifferently, and then lowered their heads and got busy. Yang Jiaku sat on the ground and watched the craftsmen go back and forth, until two hours later, everyone barely finished assembling the two 'bellows', looking at the craftsmen who completed the 'bellows' or standing listlessly, Yang Jia couldn't help but sigh again, with the current system of hundreds of craftsmen, it is impossible to forge and innovate more sophisticated weapons and armor. However, this is all to be dealt with in the future, and the main task today is to get the 'bellows' in order to melt away the porous sponge iron.

It took a short time for everyone to connect the 'bellows' and the 'furnace' together, and the craftsmen around saw that Yang Jia had spent a long time trying to make this four-like out, and they all looked sideways, and even Zu Ti came out of nowhere to stand on the periphery, watching Yang Jia and them 'make a fuss'. Yang Jia saw that everything was ready, waved his hand and asked the craftsman to start igniting the fire, adding iron ore to the 'furnace', there were two young and strong craftsmen at both ends of the two bellows, and the flame at the bottom of the 'furnace' was blown by the bellows, and after a while, the boiling heat wave came to the face, and the sweat of the bean beads continued to flow from the foreheads of the craftsmen who were busy around, and I don't know how long it took, Yang Jia, who had been lying on the edge of the 'furnace', suddenly shouted excitedly, Zu Ti dialed the crowd and stepped forward, and the craftsmen did not dare to get too close to Yang Jia and Zu Ti, so they had to watch from afar. Zu Ti looked at the iron slurry derived from the 'furnace', hammered Yang Jia's shoulder and said, "Okay! Mingxin didn't expect you to do this. ”

Of course, Zu Ti is happy, he has always been on the front line of the battlefield, and the general who slashes the enemy with a saber, Zu Ti will not say this as a trick like those scholars, Zu Ti knows that those small spongy iron particles will seriously affect the quality of the weapon, and often at critical moments, those iron particles will break the saber! Yang Jia smiled and said modestly: "It's just to apply what you have learned." ”

When the surrounding craftsmen heard that the 'bellows' they made had melted away the iron particles that had been difficult to smelt in their predecessors, Mu Ran's face finally showed a hint of joy, and he looked at his companion with a smile.

Seeing Yang Jia refining the iron grains here, Zu Ti also hurriedly stopped the other 'furnaces' and ordered the craftsmen to start making the 'bellows' according to Yang Jia's design. Yang Jia didn't dare to relax at all, and immediately asked the craftsman to cast a saber with iron paste without iron particles.

The craftsman was full of nervousness, sweating profusely, and hurriedly cast the saber and handed it to Yang Jia. I don't want the young master in front of me to chop at the stones next to him, this old man looks beautiful, but he is really strong, and he actually broke the saber in his hand in a few clicks.

Yang Jia looked at the broken knife in his hand, shook his head slightly and sighed: "The carbon content is still very high, hard and brittle, not real steel!" ”

Everyone didn't understand what Yang Jia meant, Zu Ti looked at Yang Jia who was talking to himself in confusion, and the old craftsman who cast the saber hurriedly said: "Engaged in the master, this saber is already very good, in the past, there were iron particles of the saber, according to the old man's cut, it broke in two strokes, today this saber has lasted for so long, this saber is taken out, and it must be their knife that breaks." ”

Zu Ti also nodded affirmatively, but Yang Jia said; "I once saw an article in the ancient books of He Taichang's house, about explaining how to soften iron and make it less brittle. But as mentioned above, I didn't explain the specific process, and I don't remember it very clearly after too long. Of course, what Yang Jia said about He Xun is nonsense, the real situation is the ancient books that Yang Jia had read in his previous life, but now his memory is blurred, and Yang Jia really doesn't know how to get rid of the carbon content in this pig iron.

When Zu Ti heard this, he could only nod in confusion; "Then I want them to make a 'bellows' and wait for Mingxin to remember the method mentioned in the book, and then start casting weapons."

Yang Jia knew that Zu Ti didn't understand Yang Jia's words when he listened to Zu Ti's tone of writing, and it was no wonder that the time was limited! Where did Zu Ti know the carbon content of wrought iron, pig iron, and steel, and the weapons that craftsmen now cast are pig iron. Too brittle to reach the carbon content of steel. It's not that there has been no steel in the past, it's just that it just appears in the historical books, that is, those swordsmiths who spent decades of energy hammer by hammer hammer to hammer out the now long lost heirloom sword, obviously Zu Ti did not think that the softened iron that Yang Jia said was to decarburize the pig iron into a national heirloom sword. However, Yang Jia didn't explain either, he hadn't thought of the method yet, and too many explanations were all false, so when he thought of the method, he could cast a steel weapon and directly scare the ancestors.

Looking at the scene where everything was on the right track, Zu Ti said that he wanted to go back, Yang Jia also nodded understandingly, it was not a good thing to approach Zu Ti and leave Qiao County for too long, and Yang Jia believed that nothing would happen if he stayed in this Zu Ti, so he said that he wanted to leave.

Unexpectedly, Yang Jia suddenly thought of something and hurriedly grabbed Zu Ti, Zu Ti turned around in confusion and listened to Yang Jia say: "Can Fenwei cancel the identity of these artisan slaves and let them become free bodies?" ”

Zu Ti was even more puzzled: "Why do you want to turn these lowly craftsmen into free bodies? ”

"To forge better weapons, of course, and faster to forge faster." couldn't explain too much, Yang Jia had to lure him vaguely.

During the Wei and Jin dynasties, the status of the displaced people was not the lowest, the lowest was the status of the hundred workers, which was more first-class than the scholars, and it was also looked down upon. The sources of Baigong mainly include captives, prisoners, and slaves, and it is conceivable that they are looked down upon, and the control of Baigong by the imperial court is the same as that of the scholars.

Zu Ti hesitated for a long time and said: "Of course I know Mingxin's idea of strengthening the equipment of the Northern Expeditionary Army, but it is really difficult to do. The election of the officials and the people of the county that you said earlier, and the thing you said today about the removal of slaves and slaves are not something I can do, Lord! The last time you told me about the election, I wanted to explain it to you, but I have been busy with the matter of breaking off, so I delayed it. ”

Yang Jia patted his head when he heard this, how could he forget this taboo, the selection and dismissal of officials has always been discussed between the officials and the emperor, and the identity of the hundred workers has also been acquiesced by the government and the opposition since the Wei and Jin dynasties.

Yang Jia pondered slightly: "Then we will give the emperor a recital and ask for a special purpose?" ”

Zu Ti heard that Yang Jia wanted to make trouble for the emperor for these trivial things. It's a little strange, but he also knows that Yang Jia is only doing this for the Northern Expedition. The doubts in his heart suddenly disappeared, and he said: "If you play like this, will the emperor agree?" ”

Since Zu Ti asked so heartily, Yang Jia naturally wouldn't say anything like unpredictable, and he couldn't guess his intentions. Instead, he tilted his head and smiled: "How can you disagree!?" ”

Zu Ti also laughed when he heard this.

How could Sima Rui disagree! Zu Ti did not send a single soldier to Jiangdong in the Northern Expedition, and now Zu Ti has recovered Qian County, and Sizhou in the north is at his fingertips, how could Sima Rui be at this time, because of a trivial matter, to divide the relationship between the monarch and the minister?
