The nine stars gathered on the sky suddenly erupted with brilliant starlight, and the bright light vibrated down like clouds, like a sea of clouds, and like a galaxy, rolling down. On the ground, the Yin Qi of the Netherworld Pool was vigorous, and the rolling Yin Fire spread upward, like a raging sea, continuously.

Two forces, one yang and one yin, yin and yang, the power is consolidated!

The two forces of yin and yang, which are rolling like a tide, collide with each other, making the surging sea of fire blaze.

Situ Yi urged the Nine-Star Great Array, attracting the two forces of yin and yang, and blessed it on the sea of yin and fire, as if he was holding a gas button, turning it to the maximum.

Suddenly, the two temperatures of the air collided with each other, and the white mist that rose up quickly spread in the air, turning into a fog curtain like white water vapor, which was continuous, forming an invisible net that enveloped everything.

Judge Zhao couldn't bear this huge pressure and left first.

Only Situ Yi was left, in the name of the Lord of the Yin and Yang Dao, urging the heavens and the earth to change, rolling power, and shaking above the heavens and the earth.

The solid and stubborn ore and metal were quickly purified in the thin flames, and the impurities in it were directly vaporized, and the remaining essence turned into a flowing liquid that could be precipitated.

Hundreds of catties of ore and metal materials, in the end there is only a small part left, the number is less than 10,000 catties, all the other impurities and other substances, are refined and evaporated, on the ground converged a colorful liquid, but can not be fused with each other.

The refining of metal materials is nearing the end, and the next step is to fuse the liquid of these precious essences with the bones, bones, and scales left behind by the Heavenly Rank Great Demon Giant.

Situ Yi waved his hand, and the thin flames spewed up, rolling up the bones of a big demon.

This big demon is the first demon that Situ Yi killed, the Sky Devouring Eater.

A jealous and greedy demon who swallows all food in his mouth. It's like a glutton, and those who come don't refuse.

Refining the bones of the big demon is a delicate job, and I don't know how to refine metal materials, refine ores, and remove impurities. Only keep the essence. The most important thing here is to take the bones of the Heavenly Rank Great Demon, use it as the main body, and then add various precious metal essences to smelt it into it, and then refine the prototype of the divine sword.

One of the most critical places is to preserve the essence of the big demon.

For example, this Heaven Devouring Ogre, the most powerful ability is above that big mouth. It can devour everything in the world, and with the improvement of strength, it can even devour the sun, moon and stars, engulfing everything, and the power is unimaginable.

What Situ Yi did was to preserve this precious ability and not fundamentally destroy it.

Therefore, this process is called a very delicate and delicate work. Situ Yi pointed at the body of the Heaven Devouring Eater, carefully controlling the Yin Fire. In order to prevent destruction, the parts above the large mouth are wrapped with divine power, and the amount of fire of the Yin Fire is carefully controlled.

This calcination process required continuous time, and it was naturally impossible for Situ Yi to refine this divine sword.

In order to better cooperate with the sword formation, it is best for the four great divine swords to succeed together. Between each other, in the yin fire, there is a certain connection, which in turn enhances the power of the Heaven Killing Sword Array.

The second end of refining is the ancient giant. The essence of the essence is the essence flowing in the bloodline, it is rumored that it is a monster born from gods and demons, because the bloodline contains two different forces that collide with each other, and it is the most important thing to separate it from the body of the giant.

This time, Situ Yi directly conjured up a giant cup of heaven and earth, spraying flames in all directions without dead ends, carefully burning the bones of the giant from all angles, and carefully stripping out the power hidden in the depths.

The furnace of heaven and earth, a steady stream of netherworld flames and the flames of the stars, emerged from it without reservation, gathering from all directions, under the control of Situ Yi, the flames were not vigorous, nor weak, carefully burning the corpse of this giant sin, and working slowly, in order not to destroy the magical power preserved in the depths of the giant sin.

As for the elemental non-living body, the mountain stone giant did not have so many scruples, the essence of his whole body was stored in the bones, as long as all the bones were completely burned, the most precious things treasured in them could be preserved.

For example, this kind of elemental non-living body, the last thing that is preserved, is called the 'elemental pronucleus', which is a very precious elemental essence that can only be accumulated after the elements have been quite concentrated and accumulated.

Just like the earth element protocore accumulated by the mountain stone giant, this kind of thing is very precious, if it is placed on the territory of the Great Sui Dynasty, it is enough to exchange for a sword controlled by a heaven-level master.

It has to be said that the Heavenly Rank Great Demon or the Giant Sin, or the last preserved essence of the elemental non-living body, are all very precious treasures without exception.

And now Situ Yi relies on these precious treasures, and the sword refined by combining the pure metal liquid with the essence is conceivable, the value is so high, any one placed in the outside world may be able to set off a bloody storm.

Subsequently, Situ Yi took care of the last Heavenly Rank Great Demon, and the way of refining the Heaven Devouring Demon was not too special, preserving its most critical parts, and after being scorched and quenched by the Yin Fire, he took the dross and preserved the essence, and then prepared for the final refining of the Divine Sword.

......

In the process of refining the origin energy of the four-headed Heavenly Rank Great Demon Giant, Situ Yi didn't seem to have much effort, but it was quite exhausting.

Even if he was prepared, at this time, Situ Yi still felt a lot of fatigue.

"This process of refining the soul origin is the key. ”

It can be seen that Situ Yi was also a little surprised by the huge consumption of refining.

However, seeing the gradually forming bones, in the beating flames, a phantom of the sky-swallowing demon suddenly filled up from the yin fire, and the body that seemed to be a little blurred, opened a big mouth, and sucked in the yin fire around it, and the flames that spewed suddenly dropped a lot, but the phantom of the sky-swallowing demon became a lot clearer.

There is no doubt that Situ Yi preserved the essence of the whole body of the heaven-swallowing demon, refining it with yin fire, which is to stimulate the remaining will and soul in the body, and then use the means of the netherworld to stabilize it, as the sword spirit of the divine sword that is about to take shape, to preserve the powerful ability of the original big demon, as well as the ability to evolve the power of the law.

It can be seen that Szeto Yi's consideration is comprehensive, not without purpose. (To be continued.) )
