Song Bo stood in front of his earth blast furnace and looked at the fiery red iron flow, his eyes began to turn red. From a physical and optical point of view, the color of the iron reflected by the eyes looked very red. But from a psychology and medicine point of view, we can only say that he saw money, a lot of money, which caused his heart to be beat faster and his eyes were congested. Song Bo's breathing was a little thicker.

But those are not money, but the torrent of steel. The iron flows into the mold grooves that have been prepared long ago. The reason why soil is used to make mold grooves is because today's iron is relatively large. If sand is used as molds, the sand in the blacksmith shop is not enough to use. In the end, if there is no way, it can only be used to use soil to make it all at once. So Song Bo used soil to make some strip molds, which just happened to be used to carry the iron. The iron produced in this way is just the shape of a strip. If it is used for weapons or farm tools for iron making, it is easier to make iron. Unlike iron ingots, although it is easy to store, it is not so practical to make utensils. Because it is not very convenient to heat the iron ingots. In addition, if it is folded and forged, the iron ingots must be processed in advance before they can be used. Therefore, they are all made into strips. In this way, using the whole tool to make a big tool directly. If it is made into a small tool, it is enough to cut it out. It is convenient to do whatever you want.

Now at the other side of the slag outlet of the earth blast furnace, Wang Blacksmith and Shi Blacksmith were holding a big iron hook and hooking something out. But it doesn't seem to be a lot (of course there is not much nonsense, it's good to have three percent of it.). They are all red, like sticky magma, but these things must be lighter than iron. Of course, some of them are iron. But not a lot. In fact, Wang Shi and the two blacksmiths are doing it happily now. This feeling has not been gone for decades. They are like children, taking out the only little bit of waste.

After a while, slag began to appear at the iron outlet. This means that the iron in the furnace is about to flow out. At the same time, the soil mold is almost used up, and there is no longer anything else on the slag outlet.

Song Bo asked Zhang Blacksmith, who was calling the mold, to take a crucible for steel stir-frying. He himself replaced Zhang Blacksmith to change the mold. Zhang Blacksmith is really familiar with this place. He brought something like a big basin shortly after a short time. (The method of stir-frying steel is more complicated, so I won’t say it carefully) Song Bo was stunned, "This is the crucible for stir-frying steel? Yes, right?" It is normal for Song Bo to be surprised. After all, modern steel is made from a large furnace with two steps. Goodbye, the ancient steelmaking furnace will go to the Central Plains to see the historical relics of the Han and Tang Dynasties. It is said that there is a stir-frying steel stove in Henan.

"That's right, this is the pot used for stir-frying steel. My boss will wait for me to get the iron powder." Zhang Blacksmith ran to the south house to go to the iron powder used for stir-frying steel. This is used as a catalyst when stir-frying steel.

Song Bo stopped the bellows for air supply and carried out the two heating charcoal furnaces under the air inlet duct. There was no way to stir-fry the steel and heat it. Otherwise, the thicker the iron will become, and it will stick to the mixer. However, the heated charcoal furnace was burned for several hours and was so hot that it could not be moved by hand. Song Bo could only find a helping helper to carry the two furnaces with wooden sticks before he could take them out. If the whole furnace had not been separated from the sand in the middle, the whole furnace would have been red. There might have been a high temperature of thousands of degrees.

After the stove was brought out, Song Bo took the big basin and picked up the last bit of iron. When the last drop was sent to Song Bo into the crucible, the earthen blast furnace began to cool down. Waiting for Song Bo to use it next time. Although this was a waste, Song Bo had no choice but to do so. After all, the iron was still under control. There was not so much iron to practice. I could only stop the furnace first and wait for the next time to practice.

Song Bo put the crucible on the charcoal stove and continued to heat it. At this time, because there was nothing else, the blacksmiths found a place to rest and the idles had already returned home. Song Bo found a pottery stick like a shit stick used by the blacksmith before. He kept stirring in the crucible. He was happy while stirring. From time to time, he grabbed a handful of iron powder and sprinkled it in. The iron powder melted like snowflakes when it encountered water. Of course, the water here was iron.

"Did you think my dad is really stupid? It's dark now. I'm still messing with that stick. Did he take out a manure before? It's so mixed! How did I find such a dad? It's too much. He even told us that he was a blacksmith. He never saw him wiping the iron hammer this day. He had already known that he was just a wooden hammer or a charcoal. Really, I had known that he was such a man who took out a man who had sex with a man from the street. I would rather find an old man who walked through the street to learn. Didn't he say that our Song family is the blacksmith of the times? How could he compete with the old man on the street to trade? It's so embarrassing." Song Bingyan covered his face with one hand, and his mouth was very helpless. Obviously, outsiders watched the excitement, and insiders looked at the tricks. How could Song Bingyan know what Song Bo was doing!

"You are embarrassed, are you? You don't have to put the manure into the iron. It's called fried steel. I just asked Master Zhang." At this time, the Song Bingshou, who always held the pancake, suddenly spoke behind Song Bingyan. It was obvious that he felt embarrassed at first, but he was still a rather ghost guy. He secretly ran to Zhang Blackskin who was resting, and asked Zhang Blackskin happily. Under the influence of that invincible and cute innocent smile, he knew very easily what Song Bo was doing. In order to celebrate that he knew what his dad was doing, he even took out an extra pancake.

"He is frying steel? No matter how I look at it, it still looks like I am consuming manure. It feels that it has nothing to do with frying steel. I really don't understand whether frying steel is frying steel is consuming manure? This is too much." When Song Bing and his younger brother were complaining, Song Bo's thick screams came over the edge of the charcoal stove.

"Bingyan comes here, take the bamboo tube and come here to help." Song Bo didn't say why he just called his eldest son over.

"What are you doing? Dad, I won't let me take a stick and take out a manure like you, right? I'll stir it in this pot, right?" Although Song Bingyan said that he was unwilling to do it, he was not slow at all. This personality is really like his face, and he looks cunning and philanthropic. But he is honest and powerful in his heart.

Song Bingyan took the bamboo tube to Song Bo, "Dad, I'm bringing the bamboo tube, what's the purpose?" Song Bingyan looked unhappy. But he didn't seem to have such a meaning. Because Song Bingyan had a smiling face, how could this face look merciless?

"No need to disturb you, there is a wind bag over there. Which wind bag you have, get it on the bamboo tube, and then start blowing the air in the crucible. Hurry. I said stop. "Stop." Song Bo seized the time and waited for a while after Song Bingyan connected the bamboo tube. Song Bo felt that it was almost done, so he asked Song Bingyan to blow the air in the crucible. At this time of the Tang Dynasty, because he had used bellows for a long time, there were not many wind bags, and generally some were not very large. A minor can move it (the author's setting). The "huhuhuhu" was not very large wind blowing out of the bamboo tube. But these winds were enough to send the oxygen needed to the iron in the crucible.

Then, I continued to stir, stir, and stir. In Song Bingyan's words, I was taking out a manure, but what Song Bingyan didn't expect, Song Bo really took a stick and drenched part of the iron on the wet mud. The red iron drops slowly turned bright white. Then Song Bo took out a big hammer, put the iron drops on the anvil, and smashed them hard with the big hammer. Only a thud sound was heard. The sound was louder, much louder than the ordinary iron thrust. Song Bo took away his big hammer and looked at the iron being beaten. He found that the small steel block had transformed, but it became not very big, and it was not as brittle and hard as high-carbon steel. In other words, it was better tough.

"Ah, okay, no need to do it anymore. Bingyan, you can go and rest. I'll do one here." Song Bo used two large iron pliers to pour the pot of molten steel into the steel mold with a layer of toner sprinkled with a layer of toner. It was said that it was a steel mold, but it was just a shallow iron pot before. Song Bo sprinkled a layer of toner on it, but this was actually insufficient. Song Bo put the iron pot into the bucket and supported it with a stone. Then he put the molten steel in. After waiting for about ten minutes, a large iron discus in the shape of an iron pot appeared. This was the first piece of steel that Song Bo had come to the Tang Dynasty. He would become an extremely sharp sword. This time, Song Bo was really lucky.
