With the huge bastard sword just barely smaller than himself, Lucifer deflected all the elemental attacks coming from his front as he got closer to the spirits. 

"Blood magic, wings." 

At the end of his words, blood once again erupted from his wrist and this time it formed a pair of crimson wings which attached themselves on Lucifer's back.

He had been looking for an opening to completely destroy the earth spirit's core which had already started regenerating its physical body, but as the other spirits easily caught on to his plans they prevented him from coming any closer, and even with his increased mobility was unable to pass.

After Receiving an order to from his master, Lucifer's clone had started distracting both the fire spirit and wind spirit.

The clone slammed his fist into the ground, creating a thick wall of magically enhanced earth that surrounded and trapped the two spirits for a short moment

*Craack!*

*Boom!*

A lance of wind had broke through the wall of earth as if it were paper.

"Foolish..."

In a split second the freed wind spirit conjured more than a dozen wind lances and shot them all at once towards the double. 

By concentrating the chi on his legs, the clone was able to dodge the incoming wind lances without getting a scratch.

*Fuuushuuu!*

An unexpected fire geyser shot up from where the double was, but due to his incredible reflexes the double was able to use a part of the blood it was made up of to create a barrier in time.

Unscathed from the attack it took head on, the double didn't waste a second and used the blood he used for the barrier and created a scythe out of it.

"Brother, let me handle this..."

The wind spirit stopped the fire spirit who was preparing to activate multiple spells and conjured a long and curved single-edged blade out of air. 

Without saying anything, the double launched itself at the wind spirit and madly swung around the weapon in its hands.

Like a seasoned warrior, the wind spirit dodged each and every attack from the scythe by moving only the bare minimum needed of its body as if it saw the weapon's trajectory, while also looking for possible openings. 

Looking back to see his double, Lucifer knew that it would not hold up for much longer and that he needed to finish the fight before his ki and mana depleted.

"Blood magic, shield." 

At his command more than a dozen bucklers made out purely of blood intercepted the incoming shower of earth swords. 

Unable to destroy the core in time, the earth spirit had already fully regenerated and was already retaliating.

'These spirits, despite the death of their master, which caused a lot of their power to deplete are still able to fight this well huh? As expected from his creations.'

While in thought, the angry earth spirit that was hungry for revenge appeared out of nowhere and swung its gigantic battle axe at Lucifer. 

Without enough time to dodge, Lucifer took on the attack with his sword.

*Craaash!*

Because of the overwhelming strength of the earth spirit, Lucifer came crashing down the earth like a meteor.

And in quick succession, the earth spirit made follow up attack and made giant earth swords rain down from above.

Noticing he was being cornered, Lucifer had erected a barrier in front of him and defended against the barrage of earth swords.

Seeing the enemy preoccupied by the assault of earth swords the ice spirit saw an opening from the side and decided to attack using her trident.

"Space magic, transport." 

Upon finding an opportunity for a counterattack as the ice spirit charged at him, Lucifer continued to focus on defending from the onslaught of earth magic and let himself be pierced by the trident, while casting space magic to transport his other arm and attack.

Lucifer grit his teeth as the attack from the ice spirit pierced his body and severely damage his insides.

 "Heh..."

The blood from inside of Lucifer's body had been infused by magic and wrapped around the trident and the ice spirit's body to make it incapable of moving.

Then, a black hole that tore through the very fabric of space appeared behind the ice spirit, and from it came out a hand.

Covering the warped hand with chi that could easily cut through a crystal, Lucifer stabbed his arm into the unmoving ice spirit's body and pulled out its core.

"End of your rope..."

Without any hesitation Lucifer crushed the perfectly round blue orb in his hand, preventing the spirit from regenerating and permanently destroying it. 

"One down..."

While the crushed core pieces in his hand dissipated, Lucifer stopped the space magic and immediately created a blood shield as he saw something approaching from his side.

*Claaang!*

The enraged wind spirit swung down its sword with power that could possibly split a mountain, but reacting fast enough, Lucifer's magic caught the blade and nullified it's damage. 

"Void magic, zero zone."

Then with Lucifer's words the entire place turned pitch black, an infinite zone of nothing but darkness, with only Lucifer and the spirit's inside visible. 

"I have one minute to end this battle." 

Said Lucifer as he snapped his fingers, and from the darkness appeared hundreds of crimson spears.

The entire area had turned into Lucifer's domain, giving him full control of everything inside it. 

Unable to use their main strength which is their magic, the remaining spirits were nothing more than sitting ducks.

"Now show me how much you can take."

_ • _ • _ • _

Crushing the orange colored orb under his foot, Lucifer had completely annihilated all of the elemental spirits.

Leaving the apocalyptic looking battlefield, the demon continued to move forward.

After a few minutes of walking Lucifer reached something that looked like a layer of thin green glass blocking his path.

'This is the barrier that's been weakening me the whole time, seems like even his magic is not impervious to the passage of time.'

Putting his palm on the surface of the barrier, Lucifer said one word, "break."

With a loud shattering sound the barrier broke into pieces and dissipated.

"Hm?" 

Looking in front of him, Lucifer saw the old dusty skeleton of a man in robes sitting on a throne made of earth, it was the remains of a once legendary mage. 

Coming closer to the skeleton, a few words escaped Lucifer's lips, "good try kid."

With a snap of his fingers the skeleton burst into flames, and on the floor the demon saw a round marble platform with runes engraved on it, a teleportation circle. 

'I guess it's time to leave this place.'
