Naruto Bond

Lu Fei and Naruto rushed towards the group of dark ghosts. Lu Fei wielded the Thunder Flame Sword and performed the "Flame Thunder Sky Slash". The flames and lightning power on the sword instantly exploded, turning into sharp sword energy, whistling towards the group of dark ghosts. Wherever the sword energy went, the dark ghosts screamed in pain, and their bodies were chopped into illusory flickers, but there were so many of them that they soon gathered again and continued to rush forward.

Naruto used the Shadow Clone Technique, and many of the Shadow Clone Techniques cooperated with Lu Fei to form a circle, trapping the dark ghost inside. The real Naruto quickly formed a seal on the side, "Senjutsu? Wind Style? Nine-tailed Rasenshuriken!" The huge Rasenshuriken spun out with great force, like a raging tornado, sucking in the approaching dark ghosts and smashing them into pieces.

However, these dark ghosts seemed to be immortal. No matter how many times they were broken up, they could quickly recover to their original state. They also began to release a black mist, which spread and gradually eroded the surrounding space, slowing down Lu Fei and Naruto's movements.

"There's something strange about this mist, we can't let it spread!" Lu Fei shouted, and he inserted the Thunder Flame Sword into the ground, and the power of the artifact was injected into the ground through the sword, trying to disperse the mist. At the same time, he performed the "Flame Thunder Purification Slash", and the purifying power on the sword and the dark mist offset each other, and the mist began to slowly dissipate.

During the battle, Naruto discovered that the core of the dark ghosts seemed to be a dark energy ball in their chests. As long as this energy ball was destroyed, perhaps they could be truly destroyed.

"Lu Fei, attack the energy balls on their chests!" Naruto reminded loudly.

After hearing this, Lu Fei immediately adjusted his attack strategy. He jumped high, and the power of the Thunder Sword was increased to the extreme, and he performed the "Flame Thunder Overlord Slash". This sword turned into a huge flame and thunder sword energy, and slashed towards the energy ball on the chest of a dark ghost. The sword energy hit the energy ball accurately, and the energy ball shattered instantly. The dark ghost screamed and completely dissipated.

The other dark ghosts became even crazier when they saw their companions being destroyed. Regardless of their own injuries, they rushed towards Lu Fei and Naruto in waves, trying to overwhelm them with their numerical advantage.

Lu Fei and Naruto cooperated with each other, dodging the attacks of the dark ghosts while looking for opportunities to destroy the energy balls on their chests. After a hard fight, they finally eliminated all the dark ghosts.

But at this moment, a low roar suddenly came from the dark abyss, as if some huge and evil creature was enraged by their fight. Then, a huge dark beast slowly rose from the abyss. This beast was as big as a mountain, covered with black scales, each scale flashing with a cold luster, its head was like a small hill, its huge mouth was full of sharp fangs, its eyes were blood red, emitting a frightening fierce light.

"What kind of monster is this? It looks difficult to deal with." Naruto said with a frown.

Lu Fei's expression was solemn. "No matter what it is, we cannot retreat. The evil in this dark abyss must be stopped!"

The dark beast opened its bloody mouth and spewed a black energy beam towards them. Wherever the beam went, the ground was instantly torn apart, forming a huge gully. Lu Fei and Naruto quickly dodged to the sides. While dodging, Lu Fei performed "Flame Lightning Slash", and a flame lightning sword energy shot towards the beast's eyes, trying to interfere with its attack.

The beast dodged the sword energy easily, then swung its huge claws and grabbed Lu Fei. Lu Fei dodged to the side, and the Thunder Flame Sword slashed at the beast's claws. The blade collided with the claws, splashing sparks. Although a shallow mark was left on the claws, the beast's power was too strong, and Lu Fei was shocked and flew backwards, falling heavily to the ground.

Seeing this, Naruto used the "Senjutsu? Lava Release? Rasenshuriken" and threw it towards the belly of the giant beast. The high-temperature Lava Release Rasenshuriken, with blazing flames, accurately hit the relatively weak part of the giant beast's belly. The giant beast roared in pain, the scales on its belly were scorched, and black blood flowed out of the wound.

Lu Fei took the opportunity to get up and used the "Flame Thunder Demon Slash". He increased the power of the Thunder Flame Sword to the extreme and slashed at the wound on the beast's abdomen with all his strength. This sword contained a powerful force and successfully deepened a crack on the wound on the beast's abdomen.

The dark beast was enraged, and it began to shake its body wildly, causing the surrounding space to tremble violently. Its tail was like a giant whip, sweeping towards Lu Fei and Naruto.

Lu Fei and Naruto quickly jumped to avoid it. During the battle, Lu Fei discovered that after the giant beast launched a powerful attack, its neck would be stiff for a short time, and there might be a flaw in the defense there.

"Naruto, attack its neck when it's stiff!" Lu Fei shouted.

After hearing this, Naruto immediately ordered his shadow clones to restrain the dark beast. The real Naruto used the "Senki Technique - Super Large Rasengan" and threw it at the moment when the beast's neck stiffened.

The giant jade Rasengan accurately hit the neck of the beast, and the beast let out a dull roar. After the neck was hit, its movements became slow. Lu Fei took the opportunity to perform the "Flame Thunder Final Slash". He completely integrated the power of the Thunder Sword and the artifact and slashed at the heart of the beast with all his strength. This sword contained a powerful divine power and successfully pierced the heart of the dark beast. The huge body of the dark beast fell down with a bang, smashing a huge deep pit on the ground.

As the dark behemoth fell, the dark aura in the dark abyss began to slowly dissipate, and the sky gradually regained some light.

"Finally we got rid of this big guy." Naruto breathed a sigh of relief.

“Well, but we still have to go deeper into this dark abyss to see if there are other sources of dark forces and eliminate them completely.” Lu Fei said.

They walked cautiously towards the dark abyss, and at the bottom of the abyss, they found a huge dark magic circle. Strange runes flashed on the magic circle, and a strong dark atmosphere filled the air.

"This magic circle must be the core of the dark abyss. We must find a way to destroy it." Lu Fei said.

They began to study the structure of the magic circle, trying to find a way to crack it. During the research, they found that there were some energy connection points between the runes of the magic circle. As long as these connection points were destroyed, the power of the magic circle could be weakened.

"Naruto, let's start from these connection points and destroy the magic circle!" Lu Fei shouted.

They began to move. Lu Fei wielded the Thunder Flame Sword and performed various fire and lightning moves, slashing at the energy connection point of the magic circle. Naruto performed the Shadow Clone Technique, and the shadow clones assisted Lu Fei in the attack. The real Naruto gathered chakra on the side, preparing to perform a powerful ninjutsu to deliver a fatal blow.

With their efforts, the energy connection points of the magic circle were destroyed one by one, and the light of the magic circle gradually dimmed. But just when the magic circle was about to be completely destroyed, a powerful dark force suddenly surged out of the magic circle and enveloped them.

This dark force tried to erode their bodies and wills, plunging them into endless darkness. Lu Fei and Naruto gritted their teeth and fought tenaciously against the dark force with their strong will and powerful strength. They completely integrated the power of the artifact with their own power and launched their strongest joint attack. Lu Fei's Thunder Flame Sword and Naruto's Rasenshuriken, which combined the power of immortality and artifacts, flew towards the core of the dark force at the same time.

With a thunderous roar, the attacks of both sides collided. Powerful energy waves spread in all directions, and the entire dark abyss shook violently under the impact of this force. Cracks began to appear in the walls, and stones fell one after another.

In the fierce energy collision, Lu Fei and Naruto gritted their teeth and persisted. They had only one belief in their hearts, which was to destroy the dark magic circle and protect this continent. In the end, their power gradually gained the upper hand, and the dark magic circle was completely shattered under the powerful attack, turning into countless black fragments that dissipated in the air.

As the dark magic circle was shattered, the dark aura in the dark abyss completely dissipated, and the area regained its former vitality.

"We did it!" Naruto shouted excitedly.

"Well, but this is just a small step to protect the continent. We still have a long way to go." Lu Fei said.

They left the dark abyss with the joy of victory.
