The smelting process lasted three days and three nights.

During this period, Judge Zhao went back and forth several times, transporting the prepared various metal materials to the Yangshi Difu in case of emergency.

The strength of the body of the Heavenly Rank Great Demon Giant has exceeded the level of refined iron, the blood is as heavy as lead, the flesh and bones are like iron, and the muscles of the whole body are like being forged with steel and wound up.

"The effect of the Yin Fire is so great, even I didn't expect it in advance, if you change the Yang Fire Burn, the loss is not small. Situ Yi said with some emotion.

In fact, in the sea of yin fire and fire, the white bones that have gradually been stripped of flesh and blood, like white jade, in the cold flames, radiating a warm luster, a white halo, enveloping this burning sea of fire, it seems to have a little more charm.

The body belongs to the yang world, and after the death of the living being, it turns into white bones, which means that the white bones belong to the underworld.

Therefore, when refining and stripping the flesh and blood of the Heavenly Rank Great Demon Giant, the effect of Yin Fire is significant, but it is also applicable to the concept of Yin and Yang.

With the preparations in place, the refining process continued.

Situ Yi swiped his finger towards the sky, tore open a pitch-black hole, and from it fell down like raindrops of metal minerals, all kinds of precious mineral materials, swarming down and falling to the sea of fire.

Suddenly, a large number of precious mineral materials, metal materials, as if falling into the smelting furnace, the cold flame, licking the surface of the metal materials, slowly burning the mineral metals, turning into flowing liquid, the hidden impurities from the inside, into pure metal materials.

This time, in order to refine the four divine swords. Yamamon's treasury was fully opened, and all the metal materials and metal ores that had been stored for several years were all moved out in one go, and Judge Zhao looked at the countless metal ores and materials that fell from the sky like a torrential rain, but what he remembered in his mind was the empty warehouse, which was clean and there were no rats.

"I don't know how many years it will take to fill the warehouse from the new. ”

Judge Zhao thought secretly in his heart. As the planner of Yama, he is responsible for the daily operation of Yamamon, and all kinds of precious materials collected are delivered to the treasury through his hands, and the quantity and number are clearer than Situ Yi.

The origin of these precious ores and minerals, Judge Zhao knows better than anyone else, except for the ones he collected. There are also other forces that have been defeated and taken from the other party's long-accumulated treasures, and the largest sum is still looted from the White Bone Sect, such as the most precious ten thousand catties of heavy copper, the world's meteorite and other things, where do they come from, otherwise they want to raise such a large number of precious metal materials. I'm afraid it's still a bit difficult.

With such a large amount of metal deposits used at once, Judge Zhao was not without distress in his heart. But he also understands priorities.

If it is really as the young master said, refining such a terrifying divine sword, it is definitely a treasure of the Divine Needle of the Sea, and it will undoubtedly make Yama Sect become as stable as a mountain.

The great array of door guards that even the heaven-level masters can kill is enough for those big forces to think carefully before they act, otherwise it will be impossible to steal chickens and rice at that time. lost his wife and broke his soldiers.

Judge Zhao felt the solemnity of the momentum, he also closed his breath tightly, and looked at the ore that gradually softened on the surface, and the speed was not too fast. I'm afraid it will take quite a while for it to melt completely.

"The longer the time continues, the more detrimental it is to the refining of the Excalibur. With such a melting speed, completely melting into liquid, it may be that the soul of the Heavenly Rank Great Demon Giant has already been lost. ”

Situ Yi secretly pondered in his heart, observed for a while, and his face became solemn.

"Nine stars in the sky, the stars appear, triggering the netherworld, and the flames are surging!"

Still seeing the problems in the process, Situ Yi made a sudden move, pointing to the sky.

Swish!

A point of light appeared, transforming into a bright star, and the bright star light fell from the sky and gushed down, like a pillar of light, illuminating the earth, forming a surging white light.

Situ Yi didn't stop there, instead his fingers thought about the void and pointed eight times in a row.

Nine stars in a row, all over the sky, bright and bright, turned into a flowing river of stars, rolling down, like a flowing river, rushing one end at a time, hitting the sea of fire.

As if adding fuel to the fire, the height of the gushing flames quickly soared, and the flames that were originally more than 100 meters above 100 meters instantly more than doubled, and the color became darker.

Under the scorching cold flames, the melting speed of those stubborn and hard ore metal materials was undoubtedly greatly accelerated, and the liquid flowing out turned into a silvery white color after several burns.

It is the dark meteorite of the world, after removing all the impurities contained in it, leaving only the purest source of it, which looks so beautiful, exuding a noble brilliance, emitting in the air, drifting in the wind.

The metal ore weighing tens of thousands of catties was completely refined, and the remaining things were less than one thousandth of them, and the silver liquid, which weighed more than ten catties at most, was separated from the burning sea of yin fire and floated in mid-air with Situ Yi's movements.

"Shave off the impurities completely, leaving behind the most essential stuff, which is what I want. ”

After refining, there was a very small part of the substance left, which made Situ Yi very satisfied.

The Zhutian Sword Array has extremely strict requirements for the divine sword of the array, and it has very important requirements for the bearing capacity of the metal, if it contains a lot of impurities, so the refined divine sword is completely unable to withstand the powerful force, not to mention hurting the enemy at that time, I am afraid that it will collapse.

Moreover, the divine sword that Situ Yi chose to refine this time is also an extraordinary and quite terrifying divine sword, and what the sword has to carry is the power of communicating the laws that evolve in the underworld, and this power is not something that ordinary metal can carry. At the very least, it also needs to be as strong as the body of a heaven-level demon giant to withstand the impact of such terrifying power.

Otherwise, when the time comes, if you don't hurt the enemy, but hurt yourself, it will obviously go against the original intention of refining the divine sword and laying down the Heavenly Sword Array.

That was not protecting Yama at all, but on the contrary, it pushed Yama into an even more dangerous situation.

Therefore, what Situ Yi did was to keep improving, completely refining the true essence contained in the metal, and then increasing the power of the divine sword.

"Nine stars in the sky, the Big Dipper Seven Yuan, Zuo Fu, and Right Bi. The nine stars are up, the netherworld is the bottom, the upper and lower are blended, and the yin and yang are combined!" )
