Naruto Bond

Lu Fei and Naruto rushed towards the area covered by dark clouds above the town. Along the way, people were running around in panic, shouting and crying, and the originally lively and peaceful town was instantly plunged into chaos and panic.

When they approached the dark cloud, they found that black lightning was constantly striking down from the cloud. Every time the lightning hit the ground, it would cause a violent explosion, creating large pits. The surrounding houses were also shaking under the impact of the explosion, and some had even collapsed into ruins.

"This dark force is so strong, we have to be careful." Lu Fei warned loudly. He raised the Thunder Flame Sword above his head. The power of the artifact slowly flowed through the sword, ready to deal with possible dangers at any time.

Naruto also nodded solemnly, quickly formed seals with his hands, and activated the Sage Mode. Powerful chakra aura surged around him, enveloping him like a protective shield.

At this time, several huge dark puppets slowly descended from the dark clouds. These puppets were tall, tens of meters tall, and made of black metal. Their joints flashed with strange red light, and the ground shook with every step they took. They held huge weapons in their hands, some were long swords, some were giant axes, emitting a chilling cold light.

"These guys again, it looks like we're going to have another tough battle." Naruto said with a frown.

Lu Fei did not respond, he rushed directly towards one of the dark puppets. "Flame Thunder Tyrant Slash!" He shouted, and the flame and lightning power on the Thunder Flame Sword instantly exploded to the extreme, turning into a huge flame and lightning sword energy that slashed towards the dark puppet's leg. This sword contained a powerful force and successfully left a deep mark on the metal of the dark puppet's leg, but it only slowed down its movement slightly.

Seeing this, Naruto used "Senjutsu Wind Style Nine-tailed Rasenshuriken". The huge Rasenshuriken flew towards another dark puppet with powerful chakra fluctuations. The Rasenshuriken continued to grow larger during the flight, surrounded by nine tails formed by chakra, like nine agile dragons. The Rasenshuriken accurately hit the belly of the dark puppet, making a dull sound. The metal of the dark puppet's belly was slightly dented, but it still stood firmly.

After being attacked, the dark puppets roared and launched a fierce attack on Lu Fei and Naruto. They brandished their huge weapons and swept towards the two of them, with the momentum that seemed to crush everything under their weapons.

Lu Fei and Naruto nimbly dodged the attacks of the dark puppets while constantly looking for their weaknesses. In the fierce battle, Lu Fei discovered that the heads of these dark puppets seemed to be their key parts, and every time they attacked, the energy fluctuations there were the strongest.

"Naruto, attack their heads!" Lu Fei shouted.

After hearing this, Naruto immediately ordered his shadow clones to attack the dark puppets' heads. The real Naruto then used "Senjutsu? Molten Release? Rasenshuriken" and threw it at the head of one of the dark puppets. The high-temperature Molten Release Rasenshuriken flew towards the dark puppet's head, leaving a burning trail in the process of flying.

The Molten Release Rasenshuriken accurately hit the Dark Puppet's head. Under the high temperature of the Molten Release, cracks appeared on the originally extremely hard metal and continued to spread. The Dark Puppet's movements also became slower, and the red light in its eyes began to flicker.

Lu Fei took the opportunity to perform the "Flame Thunder Final Slash". He once again increased the power of the Thunder Flame Sword to the extreme and slashed at the head of the dark puppet with all his strength. This sword contained a powerful force and successfully smashed the head of the dark puppet. The huge body of the dark puppet fell down with a bang, raising a cloud of dust.

The other dark puppets became even crazier when they saw their companions being defeated. They ignored their own safety and attacked Lu Fei and Naruto even more fiercely.

Lu Fei and Naruto cooperated with each other and continued to fight with the remaining dark puppets. They continued to use powerful attack methods and gradually gained the upper hand. After a hard fight, they finally wiped out all the dark puppets.

However, just when they thought the crisis was temporarily resolved, a low roar came from the dark clouds again. This roar was deafening, as if it came from the depths of hell, making people tremble with fear.

Then, a huge dark monster slowly emerged from the dark clouds. The monster was as big as a mountain, and its body was covered with black scales. Each scale shone with a dark luster, as if it contained endless dark power. Its head was like a dragon, with huge horns and a bloody mouth. Black flames spewed out of its mouth from time to time, and its eyes were blood-red, emitting a ferocious light.

"What kind of monster is this? It looks so powerful." Naruto said in surprise.

Lu Fei tightly grasped the Thunder Flame Sword and said solemnly: "No matter what it is, we must defeat it and protect this town."

They rushed towards the dark monster without hesitation. Lu Fei took the lead in attacking. He swung the Thunder Flame Sword and stabbed at the dark monster's eyes. He knew that the eyes were often the vital parts of such large monsters. If he could hit them, he might cause considerable damage to them.

The dark beast sensed the danger, and it quickly twisted its huge body to avoid Lu Fei's attack, then swung its huge tail towards Lu Fei. The tail whistled in the wind, like a huge whip, and lashed at Lu Fei.

Lu Fei dodged to the side, and the Thunder Flame Sword slashed towards the dark beast's tail. The blade collided with the scales on the tail, splashing sparks, but it only left a shallow mark on the scales.

Naruto used the Shadow Clone Technique, and many shadow clones rushed towards the dark beast. Some of the shadow clones hugged the dark beast's limbs, and some attacked the dark beast's abdomen, trying to distract its attention and create better conditions for Lu Fei's attack.

The real Naruto quickly formed seals with his hands, preparing to perform a powerful ninjutsu. In the battle with the dark monster, Naruto found that every time it launched an attack, a scale on its back would slightly rise up, and the defense there seemed to be relatively weak.

"Lu Fei, attack its back, the scales there seem to be weaker!" Naruto shouted loudly.

After hearing this, Lu Fei immediately adjusted the direction of his attack. He increased the power of the Thunder Flame Sword to the extreme, and used the "Flame Thunder Breaking Sky Slash" to slash at the raised scales on the back of the dark monster.

This sword contained great power and successfully hit the scale on the back of the dark beast. The scale was shattered, and the dark beast roared in pain, and its body began to shake.

Naruto took the opportunity to perform "Senjutsu? Wind Style? Nine-tailed Rasenshuriken", and threw this powerful ninjutsu towards the heart of the dark beast. The Rasenshuriken continued to grow larger during the flight, surrounded by nine tails formed by chakra, like nine agile dragons.

The dark beast sensed the danger to its heart and tried to protect its heart with its front paws, but Lu Fei increased the intensity of his attack and restrained its movements.

Immortal technique? Wind escape? Nine-tailed Rasenshuriken successfully hit the heart of the dark beast. The powerful force knocked the dark beast backwards, and it fell heavily to the ground, raising a cloud of dust.

The dark monster struggled on the ground for a few times. The light in its blood-red eyes gradually dimmed, and finally it completely lost its life.

With the death of the dark beast, the dark clouds that had been covering the town began to dissipate. The sun once again shone in every corner of the town, and people came out from their hiding places, looking at the sky with faces full of relief and joy for having survived the catastrophe.

"Finally solved, this was really thrilling." Naruto wiped the sweat from his forehead.

"Well, but we can't take it lightly. The dark forces on this continent may appear again at any time." Lu Fei said.
