Naruto Bond

After dealing with the dark elves, Lu Fei and Naruto continued to explore the castle. They walked into a dark and damp passage, the walls on both sides of the passage were covered with moss, and water droplets kept dripping from the ceiling, making a crisp sound.

The passage was filled with a foul smell that made people feel sick. The ground was covered with puddles of various sizes, and one could easily fall into one of them if one was not careful.

Suddenly, a low roar came from the front, and the sound echoed in the narrow passage, making people feel creepy.

Lu Fei and Naruto stopped and looked ahead vigilantly, only to see a huge two-headed snake slowly crawling out of the darkness.

The two heads of the two-headed snake were different colors, one was black and the other was red, with a ferocious light flashing in its eyes. Its body was dozens of meters long, and its scales flashed a cold light in the weak light.

Naruto quickly formed seals with his hands, "Senjutsu·Wind Style·Rasenshuriken!" A high-speed rotating spiral shuriken formed in his hands and flew towards the two-headed snake.

The two-headed snake's black head opened its mouth and spewed out a stream of black venom, corroding the spiral shuriken.

Lu Fei waved his hands, "Ten-Tails·Lightning Release·Thunder Punishment Qilin!" A huge thunder unicorn roared and rushed towards the two-headed snake.

A stream of flame spewed out of the two-headed snake's red head, which collided with the thunder and lightning of the Thunder Kirin, causing a huge explosion.

At this time, the environment in the passage became even worse. The impact of the explosion caused stones on the ceiling to fall continuously, and the ground began to shake violently.

The two-headed snake took the opportunity to launch an attack, twisting its body quickly and pouncing towards Lu Fei and Naruto.

Naruto dodged nimbly and put his hands together, "Senjutsu·Magnetic Release·Giant Sand Iron Hammer!" A huge sand iron hammer appeared in his hands, and he smashed it hard at the two-headed snake's body.

The two-headed snake was hit and hissed in pain, but it quickly adjusted its state and attacked again.

Lu Fei formed seals with his hands, "Ten Tails·Water Style·Giant Wave!" A surging wave of water surged out from his hands and rushed towards the two-headed snake.

The two-headed snake struggled in the waves, and its scales were soaked by the water.

Naruto took the opportunity to rush forward, "Senjutsu · Tailed Beast Ball · Super Fusion!" A huge Tailed Beast Ball condensed in his hand, and he smashed it hard into one of the heads of the two-headed snake.

The powerful force of the Tailed Beast Ball hit the black head of the two-headed snake, leaving a deep crack on the head.

The two-headed snake roared angrily and swiped its tail at Naruto.

Lu Fei rushed over quickly, waving his hands, "Ten Tails·Wood Release·Senra Ten Thousand Thorns Entanglement!" Countless thorny thorns grew out from the ground and tightly wrapped around the two-headed snake's tail.

Under their joint attack, the two-headed snake finally couldn't hold on and fell to the ground.

Lu Fei and Naruto continued to move forward, and the passage gradually became wider. They came to a huge basement, which was filled with various strange experimental instruments and huge cages.

Suddenly, a group of huge mutant monsters jumped out of the cage. These monsters had twisted bodies, some had sharp claws, some had huge wings, and some were covered with hard shells.

Naruto was not afraid at all, and quickly formed seals with his hands, "Senjutsu·Wind Style·Vacuum Big Ball Rasengan!" A huge Rasengan formed in his hands and flew towards the monsters.

The monsters scattered and avoided the Rasengan's attack.

Lu Fei waved his hands, "Ten-Tails·Lightning Release·Thunder Punishment Chidori Sharp Spear!" Countless lightning bolts turned into sharp spears and shot at the monsters.

The monsters were struck by lightning and howled in pain.

At this time, the environment in the basement became chaotic. The experimental equipment was overturned by the monsters, and various liquids and gases leaked out, filling the air and forming toxic smoke.

The monsters took the opportunity to launch an attack. Some of them grabbed Lu Fei and Naruto with their claws, some used their wings to fan out powerful airflows, and others spewed flames and venom.

Lu Fei and Naruto dodged left and right in the smoke and continued to launch attacks.

Naruto seized the opportunity, put his hands together, and used "Senjutsu·Magnetic Release·Iron Sand Meteor Shower!" Countless iron sands hit the monsters like meteors.

Lu Fei formed seals with his hands, "Ten-Tails·Water Style·Water Dragon Bullet!" A huge water dragon flew out from his hands and rushed towards the group of monsters.

Under their fierce fighting, the monsters fell one after another.

The smoke in the basement gradually dissipated, and Lu Fei and Naruto were breathing heavily in exhaustion.

They continued to move forward and came to the top floor of the castle. Here was a huge observation deck that overlooked the entire castle and the surrounding scenery.

However, the observation deck was filled with thick fog, making it difficult to see far away.

Suddenly, a huge figure appeared in the fog. It turned out to be the owner of the castle - the Dark Lord.

The Dark Lord was tens of meters tall, emitting a powerful dark aura. His eyes were flashing red light, and he held a huge magic wand in his hand. The wand was inlaid with countless gems, flashing strange light.

Naruto gritted his teeth and said, "Finally I see you, Dark Lord!"

The Dark Lord sneered and said, "You guys who don't know your own limitations dare to break into my castle. Today is the day you die!"

After saying that, he waved his wand, muttered something, and a powerful dark energy attacked Lu Fei and Naruto.

Lu Fei and Naruto quickly joined forces to resist, their chakras continued to explode and collide with the dark energy.

The atmosphere on the observation deck was extremely tense, with howling winds and rolling fog.

Lu Fei waved his hands, "Ten-Tails·Lightning Release·Thunder Punishment Kirin Shocks the Sky!" A huge thunder unicorn roared and rushed towards the Dark Demon King.

The Dark Lord pointed his magic wand, and the Thunder Kirin was instantly hit by a black light and dissipated in the air.

Naruto clasped his hands together, and said, "Senjutsu · Tailed Beast Ball · Super Fusion Infinite!" An extremely large Tailed Beast Ball condensed in his hands, and he threw it hard at the Dark Demon King.

The Dark Demon Lord used his magic wand to draw a huge magic circle in front of him to block the Tailed Beast Ball.

The Tailed Beast Ball exploded on the magic circle, creating a huge impact.

The buildings on the observation deck began to collapse and rocks fell.

Lu Fei and Naruto continued to hide in the collapsed buildings while looking for the Dark Lord's flaws.

After a fierce battle, Lu Fei and Naruto finally discovered the weakness of the Dark Demon King.

They gathered their strength and launched a final attack.

Lu Fei formed seals with his hands, "Ten Tails·Wood Release·Senra Tenshō!" Countless huge branches grew out from the ground and tightly wrapped around the Dark Demon King.

Naruto clasped his hands together, and "Senjutsu·Wind Style·Vacuum Cutting Storm!" A powerful storm swept over, cutting the Dark Demon King's body.

Under their joint attack, the Dark Lord finally let out a scream, fell to the ground, and disappeared into a cloud of black smoke.

With the disappearance of the Dark Lord, the dark atmosphere in the castle gradually dissipated.

Lu Fei and Naruto looked at each other with victorious smiles on their faces.

They walked out of the castle, the sun shining on them, warm and comfortable.
