Lu Zhizi woke up as if from a dream, "Master Zhao, I will make iron right away."
He hurriedly stuffed the ten-pound iron ingot into the furnace.
As the bellows blew air, the iron ingot turned red in a short while.
Moreover, this red is different from the previous one. It is more transparent, and a layer of slag naturally peels off on the surface of the iron ingot.
The high-temperature furnace calcination has already stripped out some of the impurities in the iron ingot.
Lu Zhizi's eyes flashed with excitement. He took a deep breath, calmly picked up the iron ingot and placed it on the anvil.
His son Luda put down the bellows and picked up a big hammer.

The shack was almost filled with flying iron chips.
Lu Zhizi and his son used a big hammer and a small hammer to knead the iron ingot like dough, constantly changing its shape.
After hammering for a while, the color of the iron blank turned black and gray, and dense hammering marks like fish scales were left on the surface.
The rules are regular and beautiful, which makes people admire the craftsmanship of the Lu family father and son.
After Lu Zhizi and the other man stopped, they put the iron blank into the furnace for secondary forging.
Zhao Muyun only gave them this little, just enough to fill a furnace at most, so they had to make full use of it.
"Master Zhao, this thing called coal is really a good material for calcination!"
"If we can all use this to quench and forge iron materials, then forging tougher and sharper weapons will be a piece of cake."
Lu Zhizi let out a heavy sigh.
"Master Lu, don't worry. We'll have it soon," Zhao Muyun said confidently. "And it'll be in constant supply!"
