The roc's golden eyes were sharp as knives, making no attempt to conceal its hostility towards the tower master. Suddenly, it swung its giant claws with lightning speed, pouncing towards the tower master.

The tower master was given a critical mission. Seeing the roc's attack, he tried his best to dodge, but he was still lifted up by the air currents and almost lost his balance. His protective aura also trembled violently under the attack and almost collapsed.

The roc did not stop its attack. It flapped its wings again, its body swooping down with dazzling speed. Its target was the tower master, attempting to crush him completely with the force of its high-speed impact.

The tower master did not flinch; he felt the urgency of life and death. He suddenly stepped forward to meet the roc's charge. Instantly, a powerful shockwave spread outwards, overturning trees and sending earth and rocks flying.

The moment the two clashed, the air seemed to distort, like an epic duel. The tower master was enveloped in a green aura, his sword transforming into a green light in his hand, clashing with the roc's claws, producing a piercing metallic clang.

The massive body of the roc trembled in the air, sensing the unwavering will emanating from the tower master. Unwilling to show weakness, it roared, flapped its wings, and soared higher, attempting to attack the tower master once more.

The tower master was equally resolute, following closely behind with no less imposing presence. He knew that this battle would determine the life and death of his people, and also his own fate.

The might of the Roc could not be ignored; it was a being of the terrestrial immortal realm, possessing destructive power. Its sharp claws lashed through the air at incredible speed, each attack carrying terrifying force. Even the Tower Master, though powerful, appeared insignificant before the Roc.

The tower master brandished his sword, attempting to defend against the roc's attacks. However, each collision brought him immense pressure, nearly sending him flying. His body was riddled with wounds and blood seeping out, but his gaze remained resolute.

A cunning glint flashed in the roc's eyes as it gradually gained the upper hand. It constantly changed its attack angles, attempting to find an opening in the tower master's defenses. Each claw strike and bite from its beak left the tower master in grave danger.

However, the tower master did not give up. He began to employ even more superb swordsmanship, attempting to find the roc's weakness. His sword drew magnificent arcs in the air, each swing accompanied by a flash of green light. He tried to break through the roc's defenses and find an opportunity to counterattack.

The Roc's attack intensified; it could no longer tolerate the Tower Master's presence. It let out a deafening cry, unleashing a tempestuous storm that seemed poised to devour the entire forest. This cry, carrying the power to destroy everything, hurtled towards the Tower Master.

The tower master sensed a tremendous threat. He mustered all his strength, making his protective aura even stronger. A massive sonic wave struck the aura, creating a deafening explosion that filled the air with sparks and arcs of electricity. The aura withstood immense pressure, but it did not collapse.

The roc did not stop its attack; it charged towards the tower master again, its massive body as large as a mountain. Its goal was clear: to completely crush the tower master.

The tower master gritted his teeth, knowing that continuing like this would lead to certain defeat. He let out a low growl, gripping his sword even tighter. He began to unleash a secret technique passed down through his clan, and his aura surged once more.

The roc's claws swung down again, aiming for the tower master's vitals. This attack was incredibly fast, like a bolt of lightning streaking across the sky. The tower master was not to be outdone; his sword transformed into a green light, colliding with the roc's claws and producing a piercing metallic clang.

The immense forces collided, filling the air with a strong static charge. The Tower Master's body trembled slightly, but he steadied himself, not succumbing to the Roc's attack. He knew there was no turning back in this battle; he had to go all out, or the consequences would be unimaginable.

The roc launched a series of fierce attacks, attempting to tear apart the tower master's protective aura. Its beak opened, emitting a sharp cry, and a massive sonic wave surged towards the tower master once more. This time, the sonic wave was even more powerful, seemingly intent on destroying everything.

The tower master took a deep breath, and his green protective aura re-emerged, resisting the impact of the sound waves. Then, without hesitation, he charged towards the roc, his sword flashing green light as it stabbed fiercely towards the roc's throat.

The roc saw the threat of this attack and tried to dodge, but its speed had already slowed down. The tower master's sword pierced the roc's throat, blood splattered, and the giant beast let out a painful roar.

Despite this, the roc remained defiant. It fiercely pecked at the tower master with its sharp beak, attempting to bite him. The tower master hurriedly dodged, but the roc's beak still grazed his shoulder, drawing blood.

The battle escalated further, with both sides fighting with all their might. The tower lord was wounded in several places, but his will remained unwavering. He knew that only by defeating this giant roc could his people be saved.

The Great Roc was also in a difficult situation; its throat was injured, and blood was flowing continuously, but it remained full of fighting spirit. It regarded the Tower Master as a powerful opponent and would never retreat easily.

Their attacks grew increasingly fierce and their speed ever faster. Swords and claws, green light and electric arcs, intertwined in the air, creating a spectacular scene. Despite being covered in wounds, both the Tower Master and the Roc persevered to the end, refusing to give up.

At this critical moment, the Tower Master suddenly unleashed a powerful attack. His sword emitted a blinding green light, forming a massive vortex of energy. This vortex enveloped the Roc, trapping it within a sea of ​​green light.

The roc's cry echoed through the forest, making the entire forest tremble. Its massive body lunged at the tower master, its powerful aura causing the surrounding trees to tremble.

The tower master's expression was solemn, his eyes fixed on the roc rushing towards him. He steadied himself, and the sword in his hand flashed like a green lightning bolt, pointing directly at the roc's claws.

The immense impact sent a shockwave through the tower, and the tower master felt a powerful sense of oppression. However, he stood firmly in place, gripping his sword tightly with both hands, unwavering.

With a deafening roar, the sword clashed with the eagle's claws, producing a piercing metallic clang. Green light and sparks flew through the air, creating a spectacular sight.

The roc did not lose its balance due to the impact; instead, it flipped in the air, flapping its wings to regain its footing. Its fierce eyes were filled with fighting spirit, as if it wanted to completely defeat the tower master.

"Clang! Clang! Clang!" After several consecutive blows, the Tower Master and the Roc engaged in a fierce battle. The tremendous impact echoed around them, as if it would shatter the entire forest.

The Roc's attacks were unpredictable, sometimes slashing its sharp claws, sometimes opening its massive jaws, attempting to devour the Tower Master in one gulp. The Tower Master, in turn, retaliated with fierce sword strikes, each attack precisely targeting the Roc's vital points.

The battle reached its climax, with both sides exchanging blows without yielding an inch. The tower master was also wounded in several places, blood seeping out, but his gaze remained sharp as a sword, his will unwavering.

Suddenly, the roc opened its massive beak and let out a deafening scream. This scream, carrying terrifying sound waves, crashed towards the tower master, causing the surrounding trees to collapse under its force.
