Naruto Bond

The moment the black-robed figure released the dark power, the entire hall was enveloped by this powerful force. The darkness seemed to have life, baring its fangs and claws as it pounced towards Lu Fei and the others.

Lu Fei's eyes focused, and his hands quickly formed seals, "Ten Tails? Thunder Release? Thunder Punishment Heavenly Might Formation!" Lightning instantly formed a circular lightning formation around him, and the current on the lightning formation crackled, colliding with the dark power, emitting dazzling light and harsh sounds. The walls of the hall trembled slightly under the impact of this force, and the wall skin peeled off, revealing the mottled bricks and stones inside.

Naruto did not hesitate, "Senjutsu? Wind Style? Vacuum Great Ball Continuous Bomb!" Huge wind balls flew out from his hands, whistling into the darkness, stirring up the dark power. The chandelier in the hall shook violently, the light flickered, casting strange shadows.

Huaye Hongxu shouted, and the light of the spirit sword shone brightly, "Spirit sword? Spiritual light breaks evil!" A bright sword light pierced straight at the black-robed figure. Wherever the sword light passed, the darkness seemed to be torn apart, and the air was filled with a burning smell. The ground of the hall was scratched by the sword light, leaving a deep mark.

The Flame Demon Hall's pulley raised the flaming sword high up, "Sword of Flame? Flame Burning Heaven Rage Slash!" Flames gushed out from the sword, forming a huge wave of flames that crushed the dark forces. The high temperature of the flames caused the temperature of the hall to rise sharply, and the surrounding air became distorted.

The black-robed figure sneered and waved his hands. The dark power instantly became more intense, as if it was going to swallow everything.

Lu Fei's thunder array gradually shrank under the pressure of the dark power, but he still gritted his teeth and tried his best to maintain the power of the thunder array.

The wind balls created by Naruto were constantly being swallowed by the darkness, but he still continuously released the power of wind jutsu.

The light of Huaye Hongxu's spiritual sword struggled forward in the darkness, and the light gradually dimmed.

The flame wave from the Flame Demon Hall's windlass was also suppressed by the darkness, and the momentum of the flame became weaker and weaker.

"We can't go on like this!" Lu Fei shouted, "We must find the source of his power!"

While resisting the invasion of the dark power, everyone was observing the movements of the black-robed figure.

The hall had become a mess at this time, with bricks and stones on the walls falling all over the ground and the ground covered with cracks and potholes.

Suddenly, Naruto noticed a strange rune pattern flashing under the feet of the black-robed figure.

"That's it!" Naruto shouted.

Lu Fei instantly increased the power of the thunder array, "Ten Tails? Thunder Escape? Thunder Punishment Heavenly Power Explosion!" A powerful beam of lightning shot out from the thunder array and rushed straight towards the rune pattern.

The black-robed figure sensed their intention and tried to block the lightning beam, but it was too late.

The lightning beam hit the rune pattern, causing a huge explosion.

The dark power dissipated instantly, and the black-robed figure was knocked to the ground by the impact of the explosion.

Everyone took the opportunity to rush forward.

Huaye Hongxu's spirit sword pointed at the black-robed figure's throat, "You lose!"

The black-robed figure panted heavily, "I didn't expect you could find my flaws..."

After the battle, the hall was filled with the smell of gunpowder and dust. Everyone sat on the ground exhausted, gasping for breath.

"It's finally over..." said Flame Hall Ruri.

However, at this moment, heavier footsteps were heard from deeper in the hall.

"Are there more enemies?" Naruto stood up vigilantly.

As the footsteps got closer, a huge figure appeared in front of everyone.

This is a giant made entirely of metal, emitting a powerful aura.

"What kind of monster is this?" Huanye Hongxu frowned.

Without saying a word, the metal giant swung his huge fist towards everyone.

Lu Fei jumped up quickly, "Ten Tails? Lightning Release? Thunder Punishment Heavenly Power Flash!" The lightning hit the metal giant's fist, but only left a little mark on it.

Naruto formed seals with his hands, "Senjutsu? Wind Style? Super Large Jade Rasenshuriken!" Wind Style Rasenshuriken flew towards the metal giant, but was blocked by its arm.

The metal giant's attacks became more and more fierce. The pillars in the hall were knocked down by it, and stones from the ceiling fell one after another.

Kanono Hongo and Homado Ruri continued to attack the metal giant's legs, but to little effect.

"We must find its weakness!" Lu Fei shouted.

Everyone dodged the metal giant's attacks while looking for its weaknesses.

After some observation, they found a core device on the back of the metal giant.

"Attack that core!" Lu Fei said, pointing at the back of the metal giant.

Naruto used the power of wind jutsu to fly onto the back of the metal giant, "Senjutsu? Wind jutsu? Wind Blade!" A wind blade slashed towards the core device.

The metal giant noticed Naruto's movements and struggled desperately.

Lu Fei took the opportunity to release lightning to interfere with the actions of the metal giant.

Kanono Akao and Homado Rururu also attacked the metal giant with all their might to buy time for Naruto.

Finally, Naruto's wind blade successfully destroyed the core device.

The metal giant let out an unwilling roar and fell to the ground.

At this time, the hall had been almost destroyed, leaving only ruins.

Everyone walked out of the ruins and continued to explore the depths of the castle...
