Seeing Calvin act so decisively, Cana suddenly remembered something and yelled out, "No! Calvin!"
Amidst her wail, Calvin chuckled freely, turning slightly to reveal his profile with a reassuring smile on his face.
It was as if he were telling everyone, "It's okay, I've got this."
In the next moment, Calvin's entire body emitted a holy white light, radiant like the sun.
The brilliance almost covered the entire island. In the midst of this radiance, a tremendous roar emanated, no less imposing than Acnologia's might.
Although the light was dazzling, it wasn't blinding. Squinting through their eyes, the people could vaguely see a colossal figure within the radiance, a figure strikingly similar to Acnologia.
Two massive claws extended from within the light, stretching left and right, as if tearing the brilliance apart.
As the light dissipated, the figure revealed itself—wings, tail, and a dragon's head emerged one after another. A 'dragon' that was no less than Acnologia in size appeared before everyone.
"The White Dragon of Legend... it's that card..." Upon seeing the dragon's silhouette, Cana's expression turned ashen, tears flowing like a fountain.
The dragon before everyone was immaculately white, faintly reflecting the blue of the sky. Unlike Acnologia's brutality, it exuded a sense of strength coupled with gentleness.
"Cana... what's going on?" Mira, standing beside Cana, also felt a sense of foreboding, frowning as she asked.
But Cana could only weep, momentarily unable to speak.
"What's happening? Why did Calvin also turn into a dragon?" Natsu murmured incredulously, wearing an expression of complete disbelief. Gajeel and Wendy mirrored the same sentiment.
The White Dragon of Legend had a robust yet sleek physique. Its long neck enhanced its elegance, while its large mouth brimmed with sharp teeth, flanked by two erect bone spurs, exuding an aura of power.
Upon appearing, the White Dragon immediately engaged Acnologia. Every move was earth-shattering. Compared to the Crimson-Eyed Black Dragon, it was like the disparity between an adult and a child.
The White Dragon butted Acnologia with its smooth yet hard head, causing it to retreat a few steps. However, the black dragon quickly stabilized itself on all fours and swung its tail.
The black dragon's tail had a hammer-like structure at its tip, adorned with barbs. Its power suggested that a single swing would tear out a large chunk of flesh from the White Dragon.
The White Dragon agilely dodged the tail's swing and then extended its sharp claws, ruthlessly piercing Acnologia's body.
However, Acnologia's body was unbelievably tough. The claws only penetrated halfway before being unable to progress further. In pain, the black dragon wildly thrashed its body, attempting to shake off the White Dragon.
The movements of these two colossal creatures were immense. To Makarov and the others watching, it seemed like a battle of the apocalypse.
Ultimately, the White Dragon couldn't hold on. In one swing, it was harshly thrown away. However, it immediately rolled over, denying any opportunity for an attack.
After a brief exchange, the black dragon had grasped the challenging nature of the White Dragon. It leaped onto its hind legs, spread its wings, and soared high into the sky.
The White Dragon, upon seeing this, revealed a mysterious gleam in its emerald eyes, seemingly content with the black dragon's actions, preferring not to damage Tenrou Island.
It also ascended, engaging in an aerial battle with the black dragon.
The roars of the dragons echoed incessantly, and the earth-shaking waves of qi continued to descend. The battle between the two monsters captured the attention of everyone nearby.
The Council members, who were at some distance from Tenrou Island, were terrified. Even the most challenging situations they had encountered before didn't compare to the terror they felt at this moment.
"What is this... two dragons fighting in the sky?" Lahar wiped sweat from his brow, his pupils shrinking, fear completely evident on his face.
"The black dragon is probably Acnologia, but that white dragon, where did it come from?" Mest's expression mirrored Lahar's, but internally, he worried deeply for Fairy Tail.
Ultea and Meldy, who had distanced themselves from Tenrou Island on a small boat, watched the 'dragons' battle, their expressions filled with indescribable complexity.
"Acnologia... and a monster that can contend with it, surely, it was created by you, Calvin." Ultea's heart was deeply conflicted, perhaps with regret or maybe with dread.
She remembered how Hades had once told her that Calvin's summoning magic, except for the desperate ultimate technique, wasn't worth mentioning at all.
Based on the current situation, this White Dragon is indeed the so-called 'Desperate Ultimate Technique.' Indeed, compared to the other monsters summoned by the Summoning Card, the White Dragon truly is 'not worth mentioning.'
The battle in the sky continued fiercely, but on Tenrou Island, there was a moment of calmness. Everyone stared in shock, not sure what to feel.
Except for Cana, who continued crying, appearing entirely different from her usual carefree self.
"Cana, do you know anything about this move Calvin used?" Kildas gently stroked Cana's hair, asking tenderly.
Others eagerly listened in.
Sniffling and wiping away tears, Cana managed to regain some composure and, with a tearful voice, spoke up.
"That's the final secret technique of the Summoning Card: the Blue-Eyes White Dragon."
"The final secret technique? Isn't that cool?" Natsu, excited, exclaimed upon hearing this.
Lucy shot him a fierce look, silencing Natsu, then expressed her concern, "Such a powerful technique, it can't be used lightly, right?"
Upon hearing Lucy's question, Gray couldn't help but recall his own Ice Shell, an invincible sealing magic. He involuntarily blurted out, "Hey hey... could this be a magic that requires sacrificing life?"
Everyone's expression changed drastically, shocked and angered.
Cana nodded, tears streaming down her face again.
"The principle of the Summoning Card involves sacrifice. Summoning ordinary monsters requires sacrificing magic power, but to summon the Blue-Eyes White Dragon, one must sacrifice their life."
"Calvin's village was destroyed by a dragon when he was a child. He managed to survive because his grandfather, the creator of the Summoning Card, also used this ultimate technique."
Makarov shook his head repeatedly, deeply sighing. "So that's it. The dragon slayer of legend from years ago was referring to Calvin's grandfather."
Upon hearing this, Pansarley instinctively glanced at Chalulu, who wore a grim expression, clearly understanding that the scene she witnessed back then referred to this moment now.
"Now, what should we do? Calvin created this opportunity at the cost of his life. Should we try to escape?" Kildas appeared calm, but complex emotions flashed in his eyes.
"If the Black Dragon's target is us, I don't think sailing away will guarantee our escape," Mira said firmly, staring resolutely at the two battling dragons in the sky, her eyes filled with determination.
"Whether Calvin wins or loses, I want to witness this moment here!"
"If Calvin wins, I'll carry on his will and continue to live well. But if he loses, I'll be here, sharing life and death with him!"
Hearing this, the others sighed, but soon after, they all showed determined expressions, none of them planning to flee.
Evidently, they resonated deeply with Mira's words.
However, regardless of the outcome, Calvin's fate had been sealed. Only death awaited him.
