The temperature of the demonic fire was extremely high, burning with demonic qi, and after nearly three hours, the demon-breaking knife melted into molten iron, and the impurities in the molten iron were refined and separated.

Ice crystal ore is also regarded as a treasure of heaven and earth, the emperor killed the sky on a whim, put a fist-sized cryolite into the molten iron, the magic fire was enhanced, the cryolite bubbled mist, and was slowly refined into the molten iron.

There is more frost gas of ice crystal ore in the molten iron, a white line is bent in the molten iron, the ice crystal ore is fused in the molten iron, the temperature of the molten iron has dropped a lot, and the emperor does not dare to increase the ice crystal ore, if there are too many, there will be no way to melt the molten iron.

There were almost no good things in Emperor Killing Heaven's hands, and after looking for it in the space ring, Emperor Killing Heaven took out a bottle and a bunch of amethyst stones.

The bottle is the soul bottle that contains the angel's soul, and the amethyst contains divine power, and the emperor plans to merge this soul bottle and amethyst into the molten iron.

The Emperor Killing Heaven controlled the amethyst stone in the air, and the magic fire burned, melting the amethyst stone little by little.

Enough to melt more than two dozen amethyst stones, the amethyst stone turned into a purple liquid, Emperor Jitian carefully controlled the molten iron and amethyst liquid, the two liquids slowly approached, fused together.

After fusion, the molten iron turns into a lilac with some thin white lines in it.

Next is the Trapped Soul Bottle, the Trapped Soul Bottle is cast by the Trapped Soul Dark Iron, the Trapped Soul Dark Iron is extremely rare, this Trapped Soul Bottle has four or two heavy, four taels of Trapped Soul Dark Iron is added, and the material will be upgraded by a grade.

In other words, the current material fused with the Devil Breaking Knife, the weapon refined must be a Horcrux, and after adding the Trapped Soul Darkiron, the weapon refined must be an artifact, and this artifact is not the artifact of the garbage on the Ancient Continent.

The Demon Fire wraps the Trapped Soul Bottle, this Trapped Soul Dark Iron is more difficult to melt than the Demon Breaking Knife, the small Trapped Soul Bottle needs a large amount of Demon Fire Calcination, Emperor Jitian controls the Demon Fire to calcinate the Trapped Soul Bottle, and also controls the Demon Fire to maintain the temperature of the Demon Breaking Knife and the crystal liquid, which consumes a lot of soul power.

After an hour, the Trapped Soul Bottle had a little bit of temperature.

Two hours later, the Soul Bottle turned red, and the temperature of the bottle gradually increased.

After three hours, the patterns on the Trapped Soul Bottle began to blur and the surface began to soften.

…… Seven hours passed, and the Soul Trapped Bottle finally turned into molten iron, and the consumption of the Emperor Killing Heaven was extremely large, and the demonic energy in his body was consumed.

The demonic qi that slowly recovered in the body was only enough to maintain the temperature of the two liquids after burning, and it was impossible to fuse them.

As soon as his mind moved, the Blood Sun in the Little Demon Realm shot out a blood-red pillar of light, and the pillar of light shot into the first layer of the Blood Prison and injected into the body of Emperor Killing Heaven, helping Emperor Killing Heaven recover his demonic energy.

With the help of the demonic qi of the little demon realm, it took half an hour for Emperor Jitian to recover his demonic qi.

The two demonic fires in his hand, supported by a large amount of demonic qi, instantly raised the temperature to the limit. The Soul Trapped Dark Iron Molten Iron and the Hedron Water leaned together, fusing in the demonic fire little by little.

The Soul Trapped Dark Iron Molten Iron and the Soul Chaser Molten Iron are pitch black, and the purple amethyst liquid and the white liquid of the ice crystal ore are fused to form a light purple mixed with black molten iron, and thin white lines float on the surface.

The molten iron is fused, and the next step is shaping.

A knife appeared in Emperor Jitian's mind, a slender blade four feet long, three feet long, and a one-foot hilt.

According to the knife shape in his mind, he slowly controlled the magic fire to stretch and squeeze the molten iron, and the molten iron became the initial form of the knife.

Emperor Killing Heaven gradually withdrew the demonic qi, the temperature of the demonic fire decreased little by little, and the molten iron began to solidify from the appearance as the demonic fire decreased.

The demonic fire was extinguished, and the knife floating in front of Emperor Jitian emitted a purple light, and Emperor Jitian grabbed the knife in his left hand, and held the black flame knife condensed with demonic fire in his right hand, and began to cut the excess part of the knife.

Starting from the hilt, Emperor Jitian used the Demon Fire Knife to cut the round handle into a flat body, and the Demon Fire Knife carved a zigzag pattern on the hilt.

After carving the handle of the knife, then the blade, after a pause, the emperor began to move, and the blade was carved into a hideous dragon head, with the blade in the dragon's mouth.

The narrow blade part starts from the blade, and the magic fire knife cuts out the blade from both sides, and after careful and repeated corrections, it is repeatedly polished with the magic fire, and the blade can be said to be able to blow hair and break hair.

There are not many parts of the knife crest that need to be trimmed, but the extra iron horns are cut off, the knife surface is trimmed, the tip of the knife is cut out, and a perfect Shura knife is shaped (this Shura knife is actually a Tang knife).

The Shura Knife, holding the handle of the knife with both hands, is suitable for chopping, and is the most perfect weapon for performing the Breaking Army Slash, and the Shura Knife is quite famous in the Xiuzhen world as a lethal weapon.

After the repair is completed, the next step is the blood refining, which is also the blood refining, giving the weapon a soul.

Emperor Jitian injected a trace of his consciousness into the knife, and sliced the palm of his hand with the flame knife, and the pitch-black blood spurted out under the urging of the demonic qi.

Blood spilled on the blade, and the fierce demonic fire wrapped the blade, and the pitch-black blood was quenched into the knife, and that trace of consciousness fused with the knife.

Donate blood and quench, the lilac Shura knife exudes a cold demonic aura, the pattern on the knife body begins to change, the more blood is injected, the lilac of the Shura knife gradually fades, replaced by inky black.

The demonic fire dissipated, the quenching was completed, the Shura knife was pitch black, the cold was pressing, the emperor Jitian grabbed the Shura knife, his body jumped high, and the demonic energy was injected into the knife.

"Break the army!"

The sword qi volatilized by the Shura knife was only more than ten meters long, which was more than ten times smaller than the previous 100-meter-long sword qi. But the power has doubled.

More than ten meters of sword qi slashed down, the surrounding air instantly became cold, ice flowers fell, purple light appeared, broken bones flew in the first layer of the blood prison, and the knife qi passed, whether it was air or dry bones, they were all frozen up.

In the sword aura of this sword, Emperor Jitian felt that the purple light would cause people to have the effect of soul pause, which should be the ability of the trapped soul Xuantie.

Moreover, when using the Shura Knife, it is as easy as waving an arm, so the power of the slash increases.

The demonic aura dissipated, and the Shura Knife, which emitted a purple light, turned back to pitch black. The Shura Knife had just been practiced, and it was not very powerful, so Emperor Jitian was satisfied with the Shura Knife into the dantian and nourished it with the Star Soul Demon Qi.

Refining the Shura Knife, the Emperor Killing Heaven consumed a lot, and the Shura Knife was collected into the dantian, and the Emperor Killing Heaven sat in the stream, running the Seven Killing Demons to restore his strength.

When he left the Blood Prison, two days had passed, and there was another pile of ice crystal ore in the Little Demon Realm.

With these ice crystal ores, Emperor Killing Heaven planned to create a group of saint-level ice cultivators in the Sin Territory.
