To gather so much refined gold, Quan Yi specifically took out a million gold soul coins from his own vault.

In terms of cost-effectiveness, refined gold extracted from ordinary gold would be much cheaper.
However, such refined gold could not meet Quan Yi's requirements.
The temperature in the furnace rapidly increased under Yang Quan's scorching heat, and the refined gold, with its high melting point, softened at a speed visible to the naked eye.
Seeing this, Quan Yi immediately closed the furnace opening and opened the exhaust pipe on the side of the furnace.
The pipe extended diagonally upwards, but its top was curved downwards, and directly below the pipe's outlet was Yin Quan.
After Quan Yi closed the door, he immediately walked above Yin Quan and surrounded it with slender metal rods, constructing a simple but sturdy iron frame.
At the top of the iron frame, Quan Yi suspended a slightly smaller iron bucket, directly facing the outlet of the exhaust pipe.
Having done all this, Quan Yi landed on the ground and quietly watched everything.
By the way, the furnace and supports used at this time were all metals that had completed enlightenment.
Because only metals that have inherited the ultimate attributes can withstand extremely cold and extremely hot environments for a long time.
And Quan Yi used such precious enlightened-level metal to create the iron frame and furnace in order to extract a special metal from the refined gold that was rarer and more powerful than refined gold.
Half an hour later, Quan Yi began to hear the sound of boiling inside the furnace.
This meant that the temperature inside the furnace not only exceeded the melting point of refined gold, but also meant that it was about to exceed its own boiling point.
Finally, under the scorching of thousands of degrees of high temperature, the exhaust pipe of the furnace began to spray out golden yellow water mist.
This was not ordinary steam, but refined gold water mist formed by the gasification of refined gold liquid.
The water mist was ejected from the exhaust port, but under the extremely cold aura of Yin Quan, it was solidified into liquid before it had time to rise, and dripped onto the metal bucket suspended above Yin Quan.
Refined gold was precious, and Quan Yi would be heartbroken if he really let them fly away directly.
The temperature inside the furnace continued to rise, the spraying speed of the gold mist continued to increase, and the refined gold solid in the cooling bucket had reached about five hundred kilograms.
Throughout the entire process, Quan Yi had been activating the Scarlet Dragon Eyes to observe the situation of the mist.
The refined gold in the cooling bucket seemed to be no different from before, but Quan Yi could see the difference.
Under the super vision, the gold mist clearly lacked the substances that should have been contained in the refined gold in small amounts.
Time was still passing bit by bit.
The weight of the refined gold in the cooling bucket had reached about nine hundred and fifty kilograms.
This meant that only fifty kilograms of material remained in the furnace.
At this time, Quan Yi summoned Xiao Jin, flew to the vent, and waited for Quan Yi's command.
The Dragon Eyes stared for a long time, and just as an extremely subtle different substance was mixed into the pure gold gold mist, Quan Yi decisively ordered Xiao Jin to block the vent.
Not only that, Xiao Jin directly transformed into liquid metal, blocking the leakage of vaporized metal on one side, and entering the inside of the furnace along the pipeline on the other.
Under visual sharing, Quan Yi also saw the scene inside the furnace.
At the very bottom of the furnace, there was a shallow layer of liquid metal remaining.
These liquids, even in the high temperature sufficient to evaporate refined gold, had not reached the boiling point.
Compared with ordinary refined gold liquid, these liquids were also golden yellow, but in addition to that, they also gave people a crystal clear feeling.
"Finally, it's all extracted!"
Seeing that only these materials remained inside the furnace, a satisfied smile appeared on Quan Yi's face.
Quan Yi first put the re-solidified refined gold back into the Heart of the Raging Sun, and then lifted the furnace into Yin Quan and carefully poured out the liquid inside.
The hot metal liquid flowed into the extremely cold Yin Quan along the pipeline, and the mist generated by cooling intensified the mist around the spring.
In order not to waste it, Xiao Jin even turned into small metal flakes, constantly scraping the residual liquid on the furnace wall.
When the furnace was completely emptied, the cooling was also about to be completed.
A spherical refined gold block floated in the milky white spring water.
When the time was right, Quan Yi summoned Xiao Jin to bring him this metal ball weighing almost thirty or forty kilograms.
The color of the metal after solidification was not much different from that of ordinary refined gold, but its molecular structure and physical properties were different from those of ordinary refined gold.
Among all metals, refined gold has the most significant affinity for fire elements.
Therefore, Quan Yi often dealt with refined gold before. During the observation process, he found that a small amount of special refined gold would exist inside the refined gold, more or less.
It was more like a mutated substance that appeared during the formation of refined gold.
Although they both belonged to refined gold, its hardness, melting point, boiling point, and characteristics were superior to ordinary refined gold.
When the metal temperature returned to normal, Quan Yi reached out and took the palm-sized metal, admiring it with an extremely obsessed look.
Quan Yi held the sphere and slowly exerted force, but even when he used all his strength, the metal did not move at all.
You must know that Quan Yi's grip strength can reach the level of millions of kilograms, and this strength alone is enough to prove the power of this metal.
However, this was just the beginning.
After testing the strength, Quan Yi mobilized the soul power in his body and input it into the metal interior.
In an instant, a trace of fire-attributed soul power that poured into the metal was instantly amplified several times under the special refraction structure inside the metal.
Strong soul power fluctuations reverberated on the metal surface, and one point of power exerted several times the effect.
This was the biggest feature of this refined gold, that is, it had the powerful effect of amplifying soul power fluctuations.
This was different from attribute amplification, it had the same effect on soul power of all attributes.
In order to distinguish this metal from refined gold, Quan Yi named it Diamond Refined Gold.
Because its hardness and refractive structure were similar to the characteristics of diamonds.
Diamond Refined Gold was the best material for Quan Yi to make ring bands.
The Phoenix Blood Ruby that can amplify the ultimate fire, combined with Diamond Refined Gold that can enhance soul power fluctuations, the effect was not simply one plus one, but a multiplicative effect.
The combination of two top-level amplification materials made Quan Yi excited just thinking about it.
Moreover, the extraction of Diamond Refined Gold was far from over, it had even greater room for improvement.
If based on metal grade, this Diamond Refined Gold had not even completed purification or spirit infusion.
Next, Quan Yi's task was to hammer this top-level metal into enlightenment-level.
