While Asmodeus was fighting Nadia and Mina while Agni boosted their power with barely any of his leftover Divine Power, Surtr heard the call of his siblings and Muspel.
They never really cared about their own souls, and the reason why Surtr wasn't using their full power was because he was being considerate of them… After all, he didn't know what might happen to their Souls if he overused his powers.
They might even end up breaking and shattering apart…
However, Muspel told him loud and clear, that it was much more important to protect those that were still living, than to care for those that had already died!
And once those words reached Surtr's mind, his resolve was set.
"ASMODEUS!"
CLAAAAASSSHHH!!!
With all his stats boosted, Surtr clashed against Asmodeus, his claws slashing through his back and cutting one of Asmodeus wings with incredible ease!
SLAAASH!
"W-What?!"
Asmodeus was completely taken aback! He quickly analyzed Surtr's appearance, he had changed tremendously.
Surtr's entire body had grown up to ten times his original dragon size, now being as huge as two hundred meters, his entire body seemed to have become covered on gold and red metal, his flames coursing through each metallic scale.
His body decorated as if he had become a living armor in the shape of a furious dragon, but he was alive. His very appearance made Asmodeus step back, confused about what he was even seeing.
"My wing…!" He thought. "This little bastard cut it off so easily?! And what with that form?! It feels like I'm fighting someone completely different! How did he even learn to transform in this shape?!"
Surtr's wings spread out, with his gigantic metallic arms, encompassed by golden and white flames, with a huge halo of fire above his head and several arcs of flames behind his back, while many spheres of white and golden flames rotating above his head.
If he had to put it on words, Asmodeus thought the young fire dragon resembled the incarnation of a god of flames, the Red Orb Fragment shining brightly above his forehead, having fused with him temporarily and giving him an even more mystical appearance.
This was Surtr's "Ultimate Form", which Drake had taught him and forced him to learn before battling the Flame Emperor, which had become the only way for him to stand a chance against mighty foes he simply could not beat otherwise.
This was possible thanks to the ability to combine his own Origin Flames with his body, using his own body as a material through Heavenly Smith, and also adding the Red Orb Fragment to the combination.
Not only that though, as six fire dragon souls had fused into his body as well, emerging with their metallic heads above his shoulders and thighs, resembling pieces of fine armor. Muspel herself appeared on his chest, her head made of red and golden metal…
"I am not holding back anymore." Surtr said with a powerful voice, dashing towards Asmodeus and unleashing a barrage of punches. "[Divine Blazing Dragon's Nova Fists Rain]!"
Each of his fists was like a descending meteor- no, a miniature star! Asmodeus was unable to catch up to his incredibly fast movements, barely blocking some attacks by putting all his Divine Draconic Energy into his claws.
CRAASH! CRAAASH! CRAAASH! CRAAASH! CRAAASH!
"Urgh…! FUCK!"
BOOOOMMM!!!
Asmodeus was then greeted by a gigantic dragon breath coming from the combined heads of all of Surtr's armor, blasting him several meters away!
"W-What is this form you're using?! I can feel multiple dragons, all into one!" Asmodeus said.
"This is what my Master said to be my ultimate form." Surtr answered plainly. "But I have little time to use it, I'll kill you before that!"
FLAAASH!
Surtr appeared right above Asmodeus in a split of a second, the mighty old fire dragon barely detecting him as he greeted Surtr's legs with his own claws.
His powerful technique to imbue his Divine Draconic Energy, which he had cultivated and reinforced over thousands of years barely managed to block his kicks!
CLAAASH! CLAAASH! CLAAASH!
"Urgh…! Hahaha… HAHAHA!" Asmodeus laughed. "This is finally getting interesting, Surtr! So you were NO weakling at the-"
"SHUT UP!"
Surtr was completely furious, his Draconic Aura erupting from his body as it transformed into countless of fire dragon heads, overwhelming Asmodeus entire body with countless of bites, his scales and his protecting technique that made his body almost impenetrable were all broken by the Origin Flames!
BOOOM! BOOOM! BOOOM! BOOOM! BOOOM!
"UUAARRGGHH…!"
"You will PAY! I will NOT forgive YOU!"
Surtr mercilessly kicked Asmodeus' face several times, each time his fangs were being thrown around, his jaw almost dislocating!
CRAASH! CRAASH! CRAASH! CRAASH! CRAAASSHH!!!
"T-This little bastard is overwhelming me at this point!"
Asmodeus was growing desperate, his powers quickly erupting from his body with everything he had, trying to counter Surtr's barrage of physical blows!
"I will show you that you're still too far behind, SURTR!" Asmodeus roared, still acting stubborn and prideful. "The reason why I'm so strong is because I've mastered the usage of Divine Draconic Energies, something you lack! Now, despair! [Divine Draconic Embodiment]!"
TRUUUUMMM…!
Asmodeus attempted to intimidate Surtr by unleashing the embodiment of all his draconic powers, in the form of an even larger fire dragon surging from his Aura!
"ROOOAAARRR!"
"Bullshit." However, Surtr seemed completely… unamused. "[Divine Blazing Dragon Blade Claws]!"
His gigantic claws sliced through Asmodeus' amazing Aura and cut it down into countless pieces. Surtr's claws resembled titanic blades made of gold and silver, covered on Origin Flames that could consume it all!
SLAASH! SLAASH! SLAASH! SLAASH! SLAASH!
"W-WHAT?!"
Asmodeus was completely shocked as his Ultimate Attack was completely negated by Surtr! His little brother having completely surpassed him by using his own methods and his own strengths!
"DIE!"
With a merciless roar, Surtr's jaws opened, fusing its blazing powers with the rest of them, and unleashing an Ultimate Origin Flame Dragon Breath!
TRUUUUUMMMMM…!
Asmodeus was unable to evade, he was unable to do anything, in fact. Most of his body was already in tatters, his bones shattered!
"T-This little bastard… He's… good…!"
The old fire dragon was blown to pieces as he smiled on his last moments, acknowledging Surtr's resolve.
BOOOOOOOMMMM!!!
The last trial of Floor 100 was finally over.
Surtr and his party… have completed the Inheritance Trial!
