The Zombie Dragon looked back at Partner, angrily targeting her with a barrage of whip attacks using its tail, which was now covered on scales and pointy, sharp bones.
CLASH! CLASH! CLASH! CLASH! CLAAASH!
"Nnngghh…!" Partner groaned, she tried to avoid the hits but they were too fast, faster than she expected a giant bone monster to hit her!
Lucifer roared, the Zombie Dragon's eyes flickered for a few seconds as it heard her former name, it glanced back at Lucifer, roaring furiously back at him, only for his dragon fists to reach the monster's face and body, like blazing black meteors!
"[Abyssal Dragon Meteor Fist]!"
CLASH! CLASH! CLASH! CLASH! CLASH!
His fists moved rapidly and with extreme precision, breaking through the Zombie Dragon's defensive scales and crystals and shattering them all the same!
The enormous beast once more rolled over the floor, just for Partner and Brunhild to attack her with everyone they had!
"[Blood Catastrophe]!!!"
Partner gathered enormous quantities of Blood around her surroundings and shaped them into thousands of blades, falling over the Zombie Dragon and piercing through its body!
CRASH! CRASH! CRASH! CRASH!
"[Infernal Dragon Meteor]!!!"
Meanwhile, Brunhild gathered the power of her blazing flames within her scales and gathered it into her back, her scales began detaching themselves from her body and then falling over the Zombie Dragon like meteors, exploding into blazing explosions!
BOOOM! BOOOM! BOOOM! BOOOM!
The burning explosions of Brunhild and the piercing attacks of Partner combined together, overwhelming the incredibly resilient Zombie Dragon!
Meanwhile, Lucifer rushed forward, using his newly evolved scythe to unleash devastating slicing attacks against the Zombie Dragon, slicing through her defenses rapidly while she tried to angrily block them, resulting in her legs to be sliced off!
The beast fell over the floor, but new legs regrew anew, converging the shattered bones with crystals and miasma, this monster seemed to be regenerating almost endlessly!
She glanced at the scene from afar, using her magic to enhance the power of her allies. The battle had only started just half a minute ago but it was already becoming more and more intense.
She knew why this monster was so resilient, aside from being as powerful as an S Rank Monster, something everyone cannot even handle properly and need to go completely all out, there was another factor!
The Dungeon Core and the Evil God's Fragment, of course! Much like the previous dungeon where they fought the Ant Queen, the Dungeon Boss they were facing was the Dungeon Core's Avatar, an existence that was virtually immortal by being fueled by the Dungeon Core's Mana.
Of course, normally, the Dungeon Core would eventually run out of Mana, but that wasn't the case when they were parasitized by Evil God Fragments, who could generate energy endlessly, although a corrupted, miasma energy.
Lucifer had told Maria to just step back and find a way to deal with this, while he would take care of the Zombie Dragon for now. The battle was becoming more and more intense, each second that passed was precious time Maria couldn't waste.
She wasn't merely glancing at the battle anyways, her mind was divided into dozens of small phantoms who flew all around the Floor, seeking an area where she could infiltrate. Unlike the previous dungeon, there was an enormous thick divine miasmic barrier covering the entire floor, her phantasmal powers that allowed her the ability to trespass physical objects were unusable in this setting, unless she could blast everything, but she was trying to save her powers and energies for the moment of truth.
"Quickly, where is it?!"
She was seeking an opening within this impenetrable barrier, and using her phantoms spread everywhere, it was one of the few ways she could do this…
Meanwhile, Emeraldine, Takeshi, and Laura were preparing a powerful combined attack, combining their skills and power together like they had once done before, as a magic circle was slowly inscribed in the floor while their power converged together.
Slowly yet steadily, Emeraldine concentrated her Spiritual and Mana essence into the surrounding magic circle, runes began dancing rapidly as her two Spirits danced happily and imbued everything with their spiritual power. Her Magic Arrow began growing branches everywhere, becoming a beautiful tree in the shape of a giant cannon.
Meanwhile, the power of the two children also merged with them, their energies, blue and red from Takeshi and Laura respectively, danced with Emeraldine's conjuration. The power of the Oceans feed nature, enchanting its defensive power and growth, meanwhile the power of Flames and Explosions enhanced the nature with their offensive power.
Emeraldine kept concentrating, merging everything together with her light and nature, while looking back at Maria who was using her powers to find the entrance to the Dungeon Core's chambers…
"Maria, hurry!" She said.
The battle between the Zombie Dragon, Lucifer, Brunhild, and Partner continued and became even more fiercer as time went by, the Zombie Dragon kept regenerating more and more, generating enormous crystal claws which it used to unleash consecutive blows, all while somehow imitating her attackers magic!
Suddenly, the scales and crystals of the Zombie Dragon were engulfed on black and purple miasmic flames, which flew into the skies and started falling from within them into Lucifer and company, exploding into fiery detonations.
BOOOM! BOOOM! BOOOM! BOOOOMMM!!!
And then, as if that wasn't enough, it quickly gathered its own Miasmic Blood and shaped it into thousands of spears and swords made of them, crystalizing them and then firing them back at everyone else, like storms of endlessly slicing attacks, one after the other!
SLASH! SLASH! SLASH! SLASH! SLAAASH!
The trio had to fly and jump around, evading the devastatingly immense magic that was being unleashed against them. Partner and Brunhild were left speechless as she was copying their spells easily and making them even stronger.
"Crystal has always been amazingly talented at magic. One of her talents was the ability to easily copy spells she saw… To think even her reanimated body has inherited such a talent…!" Muttered Lucifer while gritting his teeth.
