What the hell is it doing? Its mouth... it's full of electricity! Yoichi thought frantically, trying to predict his enemy's first attack and come up with a plan to counter it.

Kenji's fire element and Urgerross's spark element didn't suffer any particular damage from each other. Moreover, both demons, though belonging to different levels, shared their draconic nature.

However, the real difference between Kenji and Urgerross lay not only in level, size, or ferocity: the thing that most distinguished the little dragon from the great white dragon was the fact that it was under the orders of a human being.

Throughout its life, Urgerross had never been subjected to anyone but Therion. On the other hand, Kenji didn't fight alone and relied on the combat ability of its tamer, using its skills to enhance his body and grant him a better chance of winning.

Simply put, the two true challengers on the floating arena of the Sanctum of Infinity were Urgerross and Yoichi. A human being mysteriously reincarnated in the body of a young tamer in an unknown world with no precise memories of his past, against a fierce and intelligent demon, descendant of the lineage of celestial beasts that had always protected the cosmic balance.

The thunderbolts accumulated in the white dragon's mouth began to crackle and travel in every direction, moving like bullets in every corner of the arena. As soon as Urgerross closed its yellow eyes, Yoichi finally realized that the dragon was about to launch a ranged attack.

"Run, Kenji! Get out of there!" he yelled, ordering his Oracle to move.

Suddenly, the white dragon's chest swelled and deflated in an instant as if it had charged its neck with compressed air. Urgerross opened its jaws wide, releasing the energy it had accumulated up to that point: an electric beam was fired from the dragon's mouth in Yoichi's direction, illuminating the arena under the dark and stormy sky.

Fortunately, the young tamer moved early enough to dodge the attack, but the power unleashed by it was overwhelming. The light ray made a deafening sound as if hundreds of lightning bolts were traveling in unison, ripping through the sky.

It was slightly irregular, with a diameter of about two meters of pure electrical energy. In addition to the beam, the outermost sparks were fired in every direction, scattering through the air and onto the floor.

*CRASH*VROOM* - The deafening noise was amplified by the floating arena's half-moon structure. The beam passed through two columns and continued undisturbed into the sky, disappearing miles away.

In a matter of seconds, Urgerross had released an inordinate amount of energy, surpassing the strength of any demon Yoichi had ever faced. The golden-winged dragon demon fought like a divine being compared to the Hebigure or the giant boar demon.

Incredibly, although the destructive energy of the electric beam was so strong that it pulverized any living thing, the arena floor below did not suffer any damage, as if it was made of highly insulating and burn-proof material.

The Sanctum of Infinity was not only the home of the thunder dragon, but also its training field, the perfect place to practice and cultivate its electrical powers.

"Where do you think you're going, human?!" Urgerross roared, repeating the same movements it made earlier and beginning to charge electrical energy in its jaws again.

I can't keep escaping without counterattacking! Come on, Yoichi... you're inside a vision! You're not facing a real dragon! Repeated the young tamer to himself, clenching the fists of his enhanced arms and sensing the glowing veins beneath the scales.

Without warning, in a seemingly senseless manoeuvre of attack, he changed the direction of his run, sprinting at great speed toward Urgerross. Kenji did the same, keeping its distance but following its tamer from behind.

I'm in here to cultivate my power, Yoichi thought again. There's nothing I can't do. I rode the supreme Dragon King who died thousands of years ago and reached an island floating in the sky! Therion would never let me face the thunder dragon if I didn't even have a chance to defeat it!

Yoichi let the heat energy released from the draconic flames flowed on his arms build up on both hands. Within seconds, his fists became incandescent, heating the surrounding air.

"Aaargh!" he shouted, unleashing his frontal attack and continuing to run right towards Urgerross' mouth, ready to fire the second electric beam.

*VROOM* - The same metallic sound of the first attack made Yoichi and Kenji's eardrums vibrate, and the bright beam of bolts intertwined with each other left the position of its creator. historical

"More, Kenji! We need more power!" yelled Yoichi a moment before the thunder dragon's attack hit him full force. Using all the breath in his lungs for those desperate words, the young tamer disappeared within that bright beam, too fast to be dodged.

"Screek!" Kenji roared, who, not being the main target of that attack, managed to dodge it without a problem by running towards the outer columns.

Meanwhile, at that very moment, Therion was observing the scene from afar. The King of Dragons was perched on the peak of the mountain closest to the Sanctum of Infinity and was intent on studying the duel of its heir, eager to see with its own eyes what the heir of the primordial flame was capable of.

When it saw Yoichi's small distant body, which was illuminated by a small red aura, disappearing within Urgerross's electric beam, Therion wrinkled its face, showing its concern.

"Uh? What the hell are you doing, my boy?" the black dragon thought aloud, narrowing its eyes on the scene and trying to peer at Yoichi's body in all that light to see if his counterattack was just a suicide move or if he had a definite plan in mind.

*CRASH* - A rumble of thunder ended the attack of the white dragon, whose face was lit up by an evil smile. Urgerross was certain that Yoichi had been torn to shreds, having been struck a very short distance from its mouth.

The innermost sparks of the beam were consumed in the air, and the electrical energy of the beam ran out, decreasing in size and revealing what was inside.
