Like a rapidly rotating drill bit, it drilled through the mountain rocks, invaded by freezing gas, and the skin and bones were brittle, and the center of the brain suddenly exploded one after another, and large pieces of frosty flesh and bones exploded with the rotation of the cone!

Driven by mana, the Ice Spirit Cold Light Cone spun and shattered the Fire Wing Flame Demon's brain, penetrated and flew out of the back of his head, flying back to Ling Xuan's hand with a large piece of blood-red ice slag.

On the door of the head, an ice cave the size of a bucket was pierced, and to the Firewing Flame Demon with a body of more than ten meters, it was like a human-sized head being pierced by a bullet. This was a demon after all, and Ling Xuan was afraid that the other party's vitality was strong, so he sacrificed the magic weapon that had returned to his hand.

The ice spirit cold light cone flew in the sky, rotating rapidly, and as it rotated, one by one, the ice spirit cold light the size of a human head burst from the tip of the sword in the center and the twenty-four ice spirits around it, and the snow-white light clusters of the ice crystal core thundered down from the sky one after another!

"Boom! Rumble! Rumble! Rumble! Boom ......"

A series of bombardments, the body was frozen, and the forehead was pierced, the Fire Wing Flame Demon completely lost any ability to resist, and was blown to pieces under the bombardment of the cold light of the ice spirit, turning into a ground of ice slag and frozen meat. Sensen's dark red blood flowed out of the frozen flesh and merged into a small river of bubbling cold.

There were hundreds of light clusters blasted out, and the spinning ice spirit cold light cone fell from the sky and fell directly into Ling Xuan's body, decomposing into a cold ice stamen and twenty-four ice lotus seeds, which landed on the Xuan Ice Crystal Lotus.

Ling Xuan's face was pale, this attack could be said to have exerted all his strength, if he couldn't kill the Fire Wing Flame Demon, he would be killed by the other party. The loss of mana is simply terrifying, and the spirit consumed by operating spiritual consciousness is also extremely great. My body and mind were so tired that I didn't want to move a finger, and I even felt like I wanted to sleep.

However, he still insisted on getting up from the ground and walked to the side of a huge pile of frozen meat.

The Fire Rock Demon is only an intermediate demon, and the memory in his soul is very limited. The Fire Wing Flame Demon is the lord, and Ling Xuan is now eager to know the information and information of the Flame Castle, and even the Demon Grand Duke Linna, who rules hundreds of forces, that Blood Pattern Succubus!

Although the soul searching technique is harmful to heaven and harmony, it is not good for cultivation and increases the calamity in the future, so it can only be endured in the future.

Casting the soul searching technique on the corpse parts, with the traction of the magic spell, Kafto's soul phantom was pulled out with a frightened expression, and when absorbing the soul memory, Ling Xuan's face appeared from time to time with an expression of amazement.

This soul searching technique is really not a loss! The Fire Rock Demon is only a small role in the Abyss Demon Domain, the Demon Lord, at least the place where he rules a city is powerful, and from his soul, Ling Xuan has obtained a lot of precious information and some interesting things.

"It turns out that in order to prevent his subordinates from being lazy, the Fire Wing Flame Demon inserted a surveillance eye in the area where the Inferior Demon and the Fire Rock Demon scooped up metal...... It really scared me, and I thought that the demons of this world would calculate! ”

The Eye of Surveillance is a lord-level eye demon, and the magic items refined are extremely precious. A surveillance eye can investigate a range of about ten kilometers, and the place where Ling Xuan descended before, not far away, happened to be inserted with a surveillance eye, which appeared from the river of fire, and was also within the detection range of the eye.

"Huh...... Luckily, this demon lord was so arrogant that he flew out empty-handed. If I take the weapon, even if I refine the magic weapon Ice Spirit Cold Light Cone, I am not an opponent, and I will be the one who dies. ”

Ling Xuan now learned that the Firewing Flame Demon still had a weapon, it was a nine-meter-long murder weapon, an all-metal war hammer called the "Fire Demon Hand", a fire-type magic weapon made of scorching iron!

"The Hand of the Firedemons Warhammer, that's a great legacy...... The legacy of the Firewing Flame Demon is not only that, it is developed! The other world is not the earth, there are enough treasures, and it is also, the world with the aura of heaven and earth will definitely produce a lot of treasures. ”

"Huh? Actually still in the cell, imprisoning an elf from the Continent of Mana? ”

After obtaining all the memories of the Fire Wing Flame Demon, Ling Xuan endured his nausea again, searching for the demon core in a large pile of frozen meat, ice slag, and blood.

Ordinary demon cores are of the first to ninth order, and the demon cores formed in the main body of the demon collar are super rank.

The super-level demon core is extremely rare in the Manna Continent of the Middle Realm, even in the Abyss Demon Domain, the Demon Lord also has a certain status, the leader of one force, and the crystallization of the magic power of the whole body is gathered, of course, it cannot be let go.

It was not easy to find a fist-sized super-level demon core from the minced flesh of the Fire Wing Flame Demon, and the fire surname energy contained in the demon core was simply majestic! Ling Xuan put away the Fire Rank Demon Core and shook his head slightly when he saw the fragments of the Fire Demon's corpse.

From the memory of the Fire Wing Flame Demon, to be precise, it was the Flame Demon through a demonic talent similar to the "Soul Searching Technique": devouring the brain, devouring the brain of an elf mage, and the increased memory was learned by Ling Xuan that the lord-level corpse is a good material for making magic items!

The double horns on the head, part of the main backbone spine in the body, the muscles and veins of the wings on the back, and even the skin are all good things. It's a pity that the corpse has been shattered into pieces by the cold light of the ice spirit, and the corpse has turned into tatters, and there is no way to store many items now.

The Xuanbing Crystal Lotus, nine petals, also stored the super-level demon core, just full, and even the cold iron condensed by the ice spirit in the river could not be put down, so it was only necessary to wait for the creation of the "Nawu Mustard Seed Talisman" to collect it.

Knowing the rules of the Abyss Demon Domain from his memory, Ling Xuan couldn't help but breathe a sigh of relief, for demons, strength is the truth. As long as he behaves more powerful than the dead demon lord Firewing Flame Demon, Grand Duke Linna, who rules over hundreds of similar "Flame Castles", should not kill him.

Of course, there must be two prerequisites for this, first, he can't be a human, and second, Kaftor rules the Flame Castle, a large number of inferior demons, fire rock demons and other demons, and still have some special talents!

This Firewing Firedemon is a high-level demon blacksmith, and the Firefeat's Hand Warhammer is not only used as a weapon, but also as an iron-striking tool used to forge items. Another huge benefit of soul searching and absorbing memories is that he has a certain amount of knowledge and experience in the forging technique of the Abyss Demon Domain.

Ling Xuan thought about the Demon Grand Duke's level, in addition to proving that he was not a human being, not only to be stronger than the Fire Wing Flame Demon, but also to show a certain value!

"Blood Pattern Succubus" Linna, that was a demigod-level demon, began to condense the law, Ling Xuan knew that it was impossible to fight against such an existence, and killed the Fire Wing Flame Demon, if it caused the anger of the Demon Grand Duke, he could only flee in the Abyss Demon Domain.

"Since whoever is strong in the abyss is honorable, now that I have killed the lord of Yanbao, I am the boss of this force! It's a very remote place, and after about thirty days, it's time for the blood-streaked succubus to send people on a routine inspection. ”

"Get the legacy of the Fire Wing Flame Demon first, and then cultivate the fragile body to increase your strength!"

Making a decision, Ling Xuan rested for a while, absorbed the aura of heaven and earth to recover some of his mana, and then pushed the fragments of the corpse of the Fire Wing Flame Demon into the river of fire, destroying the corpse and destroying the traces, and then headed in the direction of the Flame Castle.

Flame Castle, in the Abyss Demon Domain, is just a small demon territory, and there are a large number of inferior demons living in the force. These coolie-like little demons, in groups of thousands, scoop up molten iron from the river of fire, fish out metal, and collect steel materials under the watchful eye of the fire demons.

When the molten iron solidifies, it becomes a piece of fire-smelted iron that contains the breath of fire. It's not magic metal, but it's tainted with fire, and it's better than normal steel. In the Middle Realm of Mana Continent, only volcanoes are produced, and they are considered relatively valuable metals.

For the River of Flames, the fire iron made by the solidification of molten iron is just the most ordinary material. Pieces of metal fished directly from the River of Flames remain solid in lava, which is the complete combination of fire energy and metal to become magical metal.

This is "Burning Iron"!

and the iron cyan platform of lava in Kawachi, the ice-type cold iron that absorbs the frozen air of the ice spirit and is formed, which is the same level of magic metal. Whether it's scorched iron or cold iron, you can make magic weapons, and even a small piece is worth a lot.

There was even better metal in the river of fire, and the surface showed circles and circles, like the metal of the flame pattern on the magma solidified stone. That is the high magic metal: magma iron, which is equivalent to the refining of materials and the refining of scorched iron after the enrichment of mana.

In this special half-plane of the Abyss Demon Domain, there is a lot of fire smelting iron, and the scorched iron is considered a fine metal, and as for the magma iron, even for the demons, it is an incomparably precious metal material.

Looking at the Yan Fort from a distance, Ling Xuan's heart was full of amazement, it looked like a steel fortress cast in metal casting in the European medieval style! Thirty stories high, it stood majestically, illuminated by the dark red sky of the Demon Realm, revealing a glow like a fiery cloud!

A 100-meter-high steel fortress?

Not really!

If it was really a metal fortress, Ling Xuan would definitely do whatever it took to refine this steel fortress into a magic weapon. How much will a 100-meter steel fortress weigh? I'm afraid that tens of millions of tons, if you use it to smash people, it will be a big piece of meatloaf.

Firewing Flame Demon, even if he is the ruler of Flame Castle, it is impossible to be greedy for so much metal and build a pure steel fortress, otherwise Grand Duke Linna will definitely tear this guy alive. The majestic Flame Castle is actually a volcanic rock block inside, and a layer of molten iron is poured on the outside, which solidifies to form a shell of fire iron.

It's just iron-plated.

In any case, as an earthling, even after passing through the aura of Hongmeng and seeing the baptism of the great scene of the disintegration of the plane, Ling Xuan couldn't help but sigh when he saw this steel-like fortress, emitting a fiery red glow, towering on the hillside, the magnificence and roughness of the demonic building!

With Ling Xuan's current eyesight, flying in the sky and looking into the distance, he could see that there was also an open-air building, like the building of the ancient Roman arena on the earth, with a large number of inferior demons, pushing pieces of solidified fire and iron into the square inside the building with a car.

Some muscle-knotted, three-meter-tall demons named "Fierce Demons" pound the metal with heavy giant hammers. A small volcano is induced, creating a magma calcining furnace in which metal is placed, and red lava sparks are splashed in all directions with the hammer hitting.

The whole scene is spectacular!

The hammer in the forge hammer continuously forges the metal into demonic weapons, and the standard weapons are cast, and then the bad demons push them out of the forge in a cart, and store them in a huge storage warehouse nearby, waiting for the requisition from above.

This forge is actually a self-running institution, and it does not need to be supervised by a demon lord. This was a good thing for Ling Xuan, otherwise it would be easy to kill the Fire Wing Flame Demon.

Now in the Flame Castle, there are only five Rock Steel Demons, these high-level demons who are slaves.

As long as all the Rock Steel Demons are killed, there should be no danger of exposure for more than thirty days, after all, the Firewing Flame Demon sometimes sleeps in the Flame Castle, sleeping for many days in a row, and no other demon dares to take the initiative to enter the tyrannical Kaftor personal fortress!

However, more than thirty days later, the Demon Grand Duke's Blood Tattoo Succubus's subordinates will patrol here, and the matter of killing the Firewing Flame Demon will definitely be exposed. Ling Xuan planned to increase his strength during this period of time, and at the same time think of some ways to deal with it.

Ling Xuan hid in a naturally formed rocky hilly cave near Yan Castle, silently recovering his mana and spiritual sense. Basically recovering a day, the Ice Spirit Sword flew directly towards the Flame Castle, entering through a steel cavernous window.

From the memories of the Firewing Flame Demon, Ling Xuan knew everything about the situation inside the fortress, and the place he flew to was the Flame Castle Prison, which was guarded by a rock steel demon, and an elf girl was imprisoned inside.
