Ou Xuzi stood up and held it in his hand, Renji found him, and when he saw Ou Xuzi alone in a daze, he asked, "Xuzi, what are you doing?"

Ou Xuzi was a little excited, handed him the iron ore in his hand and said, "Brother Renci, look at what this is?"

Renji looked at it carefully, and suddenly said: "It is heavier than ordinary iron ore, with fine lines and blue light, it is definitely not an ordinary iron ore, maybe it is a meteorite falling from the sky, and it must contain metal components." ”

Ou Xuzi asked happily, "Really? Are you sure?"

Renji replied: "What's so difficult about this, put it in the furnace and refine it, isn't it clear whether it is gold or scrap iron?" ”

Ou Xuzi scratched his head and said, "Why didn't I think of it, Brother Renci, block fire, steelmaking." ”

Renci and Ou Xuzi excitedly ran to the blacksmith shed of steelmaking to light a fire, added charcoal, and after a while, the fire burned, more and more vigorous, put the iron ore into the crucible for smelting, the eyes of the two looked at it without blinking, the iron ore stood still in the crucible, the fierce flames burned around it, the temperature was getting higher and higher, the heat around it was rising, making people hot and breathless, and the big drops of sweat fell on the ground and were quickly roasted dry, without a trace. An hour passed, and the iron ore remained intact, with no intention of melting.

Renji wiped a handful of sweat and said, "It's strange that something is so resilient and unrefined." ”

Ou Xuzi's eyes sparkled, and he said over and over again: "Brother Renci, we have picked up the treasure, this is really a meteorite from the sky, and only it is difficult to melt, the ancestor spent three years on Zhanlu Mountain to cast the Zhanlu sword, and it took two full years to melt the meteorite alone." ”

Renji was surprised and said, "Then what should I do, two years, do we have two years?"

"It depends on whether it's a god iron or not. ”

A day passed, two days passed, three days passed, and the iron ore still did not move, not even red, and the crucible seemed to be unable to stand such a long period of intense burning, and the edges were cracked, but it trembled in agony in the flames because there was no molten iron.

Ou Xuzi was also tired and exhausted, because his eyes trembled because he stayed up all night, Miao Xuan brought cold spring water and hot milk tea, and the housekeeper Chi Na also felt strange, and came several times, but he couldn't figure out what the two were doing around the crucible to burn an iron ore that couldn't melt at all. wanted to ask, Ou Xuzi replied quietly: "Do you understand, don't ask blindly if you don't understand." ”

The butler of China was bored and left. Just don't bother.

Renji said to Ou Xuzi: "Xuzi, if you can't stand it physically, let's change shifts and burn it, I don't believe it won't melt." ”

Ou Xuzi agreed, and went back to sleep first. Leave Renji to guard and don't let anyone move.

A week has passed, Ou Xuzi has the initial hope turned into disappointment or even despair, the iron ore does not have any intention of melting, it stays in the crucible, let the fire burn everywhere, as stable as Mount Tai, Ou Xuzi said with a wry smile: "What kind of material are you, so calm and calm, I admire your quality, and I admire your humility and arrogance, calm and relaxed." Ou Xuzi was convinced. ”

In the early morning of the eighth day, Ou Xuzi, who was asleep, was woken up by Renji, and he said excitedly: "Good news for Xuzi, the iron ore has been burned red. ”

Ou Xuzi turned over and got up, turned around and walked out, and quickly came to the cast iron shed, the iron ore in the crucible was red and red like fire, red dazzling, red lovely, red made people breathless, and the atmosphere did not dare to come out.

Ou Xuzi smiled, this was the first time he had smiled in eight days.

Renji excitedly added charcoal, and the fire soared into the sky, the flames rushed, and the smoke rose everywhere, obscuring the sky and the sun.

After burning for a day, the iron ore is still red and shiny, but it does not melt.

Ou Xuzi calmed down and sat on the side pondering, and suddenly he patted his head and said to himself: "Why did I forget Master Jì's instructions, good iron ore needs to be added with special materials to urge it to melt quickly, and the so-called speed is not reached, this is the truth." ”

He got up at once and ran out, bringing a few things, including discarded scrap iron, into the crucible, the scrap iron melted quickly at such a high temperature, forming a red dazzling river around the iron ore, and the iron ore was like an island in the middle of the lake, and the crucible made a cracking sound.

Suddenly, the iron ore began to melt, so quickly, so completely, amazing things happened, the originally cracked crucible quickly healed, the red molten iron tumbled, and after a moment it was quiet, the iron ore and the scrap iron auxiliary materials were mixed together, emitting a strong luster.

Ou Xuzi looked at it intently, and said to Renji, "It's done." ”

Renji sat on the ground and muttered, "It's done, it's done, it doesn't look like it's a divine iron, it melted in eight days." ”

Ou Xuzi nodded: "It's also very good, there are all kinds of meteorites, and the texture is different, although it is not the best, it is not easy to get it." ”
