A variety of rough steel and jade embryos mixed with different binders are fed into a new type of furnace specially built by Andrari to smelt steel. Although this furnace made of black phosphate stone itself is not as hard as ordinary steel, its excellent performance in heat insulation and heat resistance is far beyond that of ordinary iron. At this point, even the "Fire Demon Hand" in Garuda's hands cannot be compared to it.

The cylindrical surface of the furnace is engraved with new runes based on the dwarven tradition and the fire demon enlightenment, which not only prevent the furnace itself from emitting heat, but also give this not-so-rare magical material the ability to penetrate the magic of fire.

Coupled with the two rows of four enclosed bellows braking by the elves' waterwheels, and the finest coke refined in the coal kilns, the blacksmiths of the Limestone Clan had no idea that the first time they tried to explore the limits of what this furnace could reach with a new idea, they would be refining some inexplicable stone dust!

But when the power of the waterwheel puffed up the bellows and the coke began to emit a scorching red light, all the craftsmen put their doubts behind them for the time being.

Can a flame burn a stone, and how much firepower does it take to actually do that!?

No one can answer the questions in the minds of the dwarves.

None of that aside, the scorching heat emitted by the furnace alone was already exciting for the master craftsmen. In addition to the underground lava, the scorching aura in front of me may be a non-mana supply furnace that represents the extreme heat of Garlandia! What's even more exciting is that if necessary, it can be equipped with an auxiliary mana power supply system!!

In the words of the nervous dwarfs - this is simply the life's work of our foundries! the ultimate expression of passion and dreams! - a powerful furnace that can smelt any known metal!

Although André was not sure if the dwarves meant the same thing as the word he remembered.

In short, in the midst of the overwhelming heat wave and the even more pressing gaze of the dwarves, this furnace, which everyone had high hopes for, finally started at full capacity for the first time!

The steel rails on the stone floor are connected to the freely moving bellows, and each time the bellows are removed to open a spatter that glows a blinding red, the dwarven apprentice next to him pours all the evenly sized coke particles into it. Then, as the air outlet of the bellows is closely connected to the furnace inlet, the exhaust vent begins to spit out a constant wave of heat that distorts the light.

The Flame Demon stared closely at the red glow of the metal heating vent, and he was constantly perceiving the subtle changes within the furnace through his comprehension of the magic of the flames, which His Highness called the changes of melting.

It wasn't until an hourglass hour later that the long-awaited "Molten Stone" finally revealed its true colors.

Once all the samples had cooled, the master craftsmen began to scramble for the marvelous creations that had broken their common sense.

"The powder is really completely melted into one piece! Look at the sheen on the surface! It's like polished corundum!"

"If it weren't for the black ash that sticks to the surface, they would look indistinguishable from those rare chalcedony gemstones!"

It was the first time they had confirmed that flames could melt not only metal, but also stones, and that this was not an undercurrent of lava hidden deep underground, brewed by the unfathomable power of the world. It is the ultimate that the mortal flame created by wisdom can do!

The dwarven masters who witnessed the advent of the new "ceramic" in person were simply going crazy! Although corundum is not a very precious gemstone, Andrei's method of almost being called an artificial gemstone is completely beyond their expectations! If corundum can be smelted, does it also mean that other gems can also be processed and obtained by this means!?

What followed was Andrei's incomprehensible and strange attitude towards these marked samples - smash, smash, burn, grind!

How can such good things of extraordinary significance be spoiled in this way! They represent the historical testimony of a new craft that has been excavated, and can almost be enshrined in the ancestral hall by the dwarves!

Some of the craftsmen who just arrived and don't know much about the children of the abyss are about to blow up.

However, it didn't take long for them to understand Andrei's intentions, and the samples that looked similar on the outside were very different from the extent of damage under repeated tests. Some are split directly from the middle into two sections, while others have only slight defects in the corners. Some of these man-made "gems" that don't look much different on the outside hide very fatal "dark wounds"!

The Children of the Abyss then selected several relatively intact samples and determined the bonding formula they represented based on the markings on them. With a wealth of experience in alchemy, Yudeon skillfully began the second round of sample mixing and proportioning through the "balance" invented by the Children of the Abyss.

There's nothing much to say, just reopen the furnace and refine it again.

......

It wasn't until the third round of testing was completed that the only formula was qualified, and Udion began to experiment with different ingredients in the adhesive under Andre's guidance, knowing that the Son of the Abyss was trying his best to find the best and irreplaceable formulation!

It was only at this time that the Dwarven Masters were impressed by the wonderful tools invented by the Children of the Abyss and this almost brutal scheme of contrasting obsolescence. It's no wonder that His Highness was able to develop a forging method that was even more advanced than the dwarven inheritance!

The keen dwarves have already discovered that this method of His Highness Andre is too efficient to use to develop new technology! The dwarves have accumulated civilization for thousands of years, and it may only take a few decades or even a few years to basically complete the reproduction under his magical means!

This patterned experiment is much more efficient than the dwarves sitting alone in the workshop and trying to do it without a plan. After the completion of this cooperation, we must carefully learn all the experience of this child of the abyss, and we must push the steel craftsmanship of our limestone clan to a new peak that is difficult to surpass!!

Although the resources consumed by this research method are unacceptable to ordinary people.

After testing the mixture of ceramics, Andrei began to experiment non-stop with the subtle effects of furnace temperature and heating time on the sample...... This time, everyone understood what this highness had planned, but they really didn't expect that he would do everything he could so meticulously, just to push the melting and casting methods of this gem to the limit of excellence from the beginning!

But if this is not the case, how can this highness create a new process that no one else can imagine!?

......

After the recipe, furnace temperature and heating degree were all determined, Andrey's planned mold finally got a phased semi-finished product. Due to the effects of melting, soot and air currents in the furnace, there will be some subtle differences in the finished ceramic products printed from the same metal mold.

That's when it's the turn of the limestone clan's lapidators, who need to recreate the porcelain molds that don't look much different on the outside into an identical, mature mold. In this process, the dwarves' innate ability to directly modify stones with soul magic to a certain extent completely highlights its important role, even if the difficulty of using spiritual power to fuse those ordinary rocks is completely incomparable to the difficulty of modifying artificial gems.

When this process is completed, the delicate and sturdy coins are housed in a frame of a long-made, heat-resistant metal mold. After adjusting the fit between the upper and lower molds to perfection with clay, the exciting minting of copper coins can finally begin!

The dwarven craftsmen slowly poured the molten red copper (1) that had already been matched and emitted a dazzling red glow into the mold. A small hole is made in the side of each die, and when the upper and lower dies are fully closed, the redundant copper solution in the cavity is squeezed into the adjacent surplus cavity. After waiting for the coin to cool, use special scissors to cut off the excess and polish it a little, and a brand new coin is finished!

Dwarven and elven craftsmen carry newly minted coins with the new numeral "1" invented by His Highness André on the obverse and Appi's sideways embossed on the reverse. Such a delicate creation is a heartfelt marvel at the creation, and the jade art-like molds create equally perfect coins. They believed that as long as everyone present kept the secrets of the coinage as they promised, no one else in the world would be able to make such a fine copper coin!

Not even a single coin in the first batch of sixteen pieces had a flaw that was visible to the naked eye!

First, a rough mold is made from a flexible metal that is easy to carve, and then a second round of ceramic rough molds are made from the rough mold. The fired ceramic mold is re-refined through the natural ability of the dwarven craftsman, and the final mold is obtained that is actually used to mint coins. Although the process can no longer be tedious, the final product obtained through these means is also unparalleled!

At this point, all the dwarves and elves have a new understanding of the wisdom and creativity of Andrari, or André Gesareth, the son of the Abyss.

Although the exclamations of the dwarven craftsmen these days were too frequent, the words of the man who knew André the most were echoed by all of his people.

"If there is any 'God of Creation' in this world, His Highness Andre must be his incarnation in the mortal world!" Barot Limestone summed up very seriously.
