The next afternoon, many villagers gathered in the open space next to the village despite the heavy rain.

After a busy night, a large thatched shed had been built on the open space. It was more than ten feet square. Although it could not block the wind, it was enough to withstand the flood pouring down from the sky.

Chu Tian has been busy here since before dawn, and now a preliminary finished product has appeared - a stove standing in the middle of the shed!

"This is the ugliest blacksmith stove I have ever seen in my life!"

Lord Rat lay on Chu Tian's shoulder, covered his eyes with his two front paws, and hummed softly as if he had a stomachache!

It was so ugly that even I felt inexplicably embarrassed!

Chu Tian made a large furnace similar to a round tripod made of clay purely by hand and did not polish it carefully, so the surface was bumpy and looked ugly, as if it had been gnawed by hundreds of mice.

On the inner wall of the furnace, Chu Tian drew dozens of simple runes to control the fire and strengthen the furnace.

Unable to open the bracelet and lacking usable materials, Chu Tian used local materials, ground up the fire copper ore, filled the crumbs into the runes, and calcined them slightly with firewood. He finally formed the most rudimentary rune array.

Although the grade is not high, fire copper is a spiritual material after all. The fire copper ore powder also contains a certain amount of spiritual essence of heaven and earth, and can be used in low-level rune formations.

On one side of the furnace is a clay tube that is as thick as a bowl and several feet long. The round furnace body and the long tube make the iron smelting furnace look like a crooked big teapot, but without a handle.

Chu Tian was very satisfied with his work.

It's made with whatever is available, without the use of magic power or soul power, and it's all done by hand. It took most of the day, but it's pretty good to be able to make such a thing!

As for the appearance, Chu Tian never cares about these, as long as it can be used!

"Just take over for the time being, and don't worry about trivial issues. Once the fire copper is refined, use it to cast a new furnace. It's not difficult." Chu Tian patted Shu Ye with a smile and freed his hands to make the mold.

There weren't any good materials, so I just used the clay dug out from the open space in the village and used Uncle Bear Paw's iron sword as a model. I printed it on two pieces of clay, and a crude and simple sword mold was made.

Lord Rat looked at this horribly crude sword mold, turned over his belly with a speechless look, and sighed heavily.

"Okay, we can start!" Chu Tian enthusiastically stacked the pieces of firewood neatly in the furnace, then a layer of crushed copper ore on top of the firewood, then another layer of firewood, and another layer of ore, and so on, overlapping for nearly a hundred layers.

When the materials were almost all stacked, Chu Tian suddenly laughed: "Oh, I'm so inexperienced. I'm used to using high-end things. I forgot to leave a vent for such a basic furnace!"

Under the strange gazes of Jiu Lao and others in the distance, Chu Tian picked up the long sword in Bear Paw and made two small gaps on the left and right sides of the furnace. The furnace, which was already ugly enough, was now so ugly that Master Rat had no face to stay here, and simply turned into a silver light and disappeared without a trace.

A dozen young men including Crab Claw who were helping at the side stared at Chu Tian's actions in a daze.

A young man who was about the same age as Crab Claw gently touched Crab Claw's arm and said, "Brother Crab Claw, did Shan Ba ​​really break his head?"

The crab claws murmured to themselves, "Yes, it's broken! If this thing can be used to smelt iron, I will chew up this furnace!"

Chu Tian heard what Crab Claw said, he turned around and smiled at Crab Claw: "Come on, after refining the fire copper, this hastily made furnace will be scrapped anyway, it's not bad to be able to fill your stomach!"

Chu Tian smiled brightly. Although the shape of this furnace was extremely ugly and crude and simple, the runes painted inside were the essence of Ziyin’s inheritance - among the most basic refining furnaces, this set of rune formations could be called a masterpiece!

Chu Tian spent a whole night using the simplest materials to refine the finest product. He finally came up with this set of rune formations which, although simple and crude, had an exquisite structure.

“Okay, stop talking nonsense. Let’s take it out for a walk!” Chu Tian waved his hand and shouted to Crab Claw and the others, “Stand back. This furnace won’t last long. After all, it’s made of clay. Be careful of the furnace exploding or you’ll get molten iron all over your faces!”

Crab Claw and the others grinned and held back their laughter, and hurriedly ran out of the shelter of the shed and stood in the rain to watch the fun.

They would rather be caught in the rain than stand in a shed and be blown away by an exploding furnace!

Although they didn't know much about iron smelting, they had heard many legends about the only village within thousands of miles that could smelt iron. According to the legend, there were always several furnace explosions in that village every year, and iron smith apprentices and porters were often killed or injured.

The term "furnace explosion" is not unfamiliar to Crab Claw and the others!

Chu Tian smiled and shook his head. He took the fire handed to him by Xiong Zhang and threw it into the furnace.

In the Divine Aperture Heaven Realm, the Fire Heaven Seal on the golden lamp flashed, and the fire suddenly burst into a dazzling flame, instantly igniting all the firewood in the huge furnace. The Fire Heaven Seal was fully activated, and in the surrounding void, wisps of flames that were invisible to the naked eye slowly gathered towards the furnace!

On the inner wall of the furnace, dozens of runes filled with fire copper ore powder lit up one by one. A layer of faint red light suppressed the flames in the furnace, forcing all the firepower to be concentrated in the furnace body and on the fire copper ores.

Fire copper ore is originally a low-level spiritual material. Its melting point is slightly higher than that of ordinary iron ore, but it is also limited.

A trace of fire power was naturally contained inside the fire copper mine. The Fire Seal activated the fire power contained in the ore, and the temperature inside the furnace rose sharply. In just a few breaths, most of the fire copper ore had turned red, and a small part of it began to melt rapidly.

There was a continuous "whoosh" sound, and flames shot out several feet high from the two vents and a long mud pipe nearby.

The roof of the thatched shed was soaked with rain, and the terribly high temperature carried by the flames caused the temperature inside the shed to rise sharply. Soon the temperature of the rain on the top of the shed also rose, and a thick layer of water vapor rose, like a layer of white clouds covering the thatched shed.

Half a quarter of an hour later, the fire copper ore in the furnace completely turned into juice.

The three runes engraved by Chu Tian on the inner wall of the furnace lit up one by one, the fire copper liquid began to rotate rapidly, the impurities in the ore slowly settled down, and only a layer of bright red fire copper melt floated on the surface.
