Naruto Bond

Lu Fei and Naruto continued to explore the mountains with the purification crystal. At this time, the mountain road became more rugged and steep, and the cold wind whistled past, scraping on their faces like a sharp blade.

When they reached a valley, they saw a thick dark fog, and faint moans of pain could be heard from the fog. They slowed down their pace cautiously and approached slowly.

The fog gradually dissipated, and a group of villagers who were eroded by the power of darkness appeared in front of them. Their eyes were empty, their faces were distorted, and there was a black aura wrapped around their bodies. They were attacking each other unconsciously.

"These villagers are so pitiful, we have to save them." Naruto looked reluctant.

Lu Fei nodded, "But be careful, they are now controlled by darkness and may attack us regardless of the consequences."

After that, Lu Fei wielded the Thunder Flame Sword, releasing a gentle force, trying to dispel the dark aura from the villagers. However, the dark aura was extremely stubborn, and it only dissipated a little before it entangled again.

Seeing this, Naruto used the Shadow Clone Technique, and the clones quickly dispersed, isolating the villagers to prevent them from hurting each other. The real Naruto quickly formed seals with both hands, "Senjutsu? Wind Style? Rasenshuriken!" He threw the Rasenshuriken toward the sky, which spun at high speed, generating a strong airflow that gradually blew away some of the dark fog, making the vision in this area a little clearer.

During the battle, Lu Fei discovered that these villagers had a black mark on their foreheads, which seemed to be the core gathering point of the dark power.

"Naruto, focus on attacking the black mark on the villager's forehead!" Lu Fei shouted loudly.

After hearing this, Naruto immediately ordered his shadow clones to change their attack strategy and attack the black mark on the villager's forehead. The real Naruto then used "Senjutsu? Lava Release? Rasenshuriken" and threw it at the forehead of a villager who was closer.

The Lava Release Rasenshuriken accurately hit the black mark on the villager's forehead. The dark aura on the villager dissipated a lot in an instant, and his eyes gradually regained a bit of clarity.

Lu Fei took the opportunity to perform the "Flame and Thunder Purification Slash". He adjusted the power of the Thunder and Flame Sword to the power of purification, and slashed at the black marks on the foreheads of other villagers one by one. This sword contained a powerful purifying force, which successfully dispelled the dark power from the villagers. The villagers collapsed to the ground one after another, with tired but relieved expressions on their faces.

"You... who are you? Where is this?" a villager asked weakly.

"We are here to help you. You have been corrupted by the dark forces, but everything is fine now," Lu Fei explained.

The villagers were filled with gratitude and thanked them one after another. In their communication with the villagers, they learned that deeper in the mountains, there was a dark castle, which was the core base of the dark forces in this area, continuously releasing dark auras and corroding everything around it.

"It seems that our next target is the dark castle." Lu Fei said.

After bidding farewell to the villagers, they headed towards the dark castle. The closer they got to the castle, the stronger the darkness became, and the surroundings became more dead silent.

Finally, the dark castle appeared before their eyes. The castle was tall and gloomy, with sharp black spikes all over the walls. Standing at the gate was a group of dark soldiers, wearing heavy black armor, holding sharp swords, with cold and evil eyes.

"Get ready for battle." Lu Fei clenched the Thunder Flame Sword.

"Okay!" Naruto formed seals with his hands and activated Sage Mode.

They rushed towards the dark castle. Lu Fei rushed into the group of dark soldiers like a flash of lightning, and when he swung the Thunder Flame Sword, the power of Thunder and Flame and the power of purification intertwined. Wherever he went, the armor of the dark soldiers was torn apart and their bodies were burned by the fire of purification.

Naruto used the Shadow Clone Technique, and many of his Shadow Clone Techniques fought fiercely with the dark soldiers. The real Naruto gathered his chakra on the side, ready to use a powerful ninjutsu to deliver a fatal blow.

"Senjutsu? Super-sized Rasengan!" Naruto shouted, and the huge Rasengan flew towards the densest area of ​​the dark soldiers. The Rasengan continued to grow in size during the flight, and its powerful force knocked the dark soldiers away one after another.

However, more dark soldiers soon emerged from the castle, seemingly endless. Moreover, among these dark soldiers were some dark magicians, who stood on the city wall, chanting something and casting black magic towards Lu Fei and Naruto.

Black magic struck like black lightning, scorching the ground and shattering rocks wherever it went. Lu Fei and Naruto nimbly dodged the magic attacks while continuing to fight the dark soldiers.

During the battle, Lu Fei discovered that these dark magicians needed to rely on the magic wands in their hands to gather dark power when casting spells, and the black gem on the top of the magic wand was the gathering point of power.

"Naruto, attack the gem on the top of the dark wizard's wand!" Lu Fei shouted.

After hearing this, Naruto immediately ordered his shadow clones to rush towards the dark magicians, trying to attack their wands. The real Naruto then used "Senpo? Wind Style? Nine-tailed Rasenshuriken" and threw it at the tip of a dark magician's wand.

The spiral shuriken accurately hit the gem on the top of the dark wizard's wand. The gem shattered instantly, and the dark wizard's magic dissipated. He vomited blood and fell from the city wall.

The other dark magicians were shocked to see their companions' fate, but they continued to cast spells. Lu Fei and Naruto cooperated with each other and continuously attacked the dark magicians' magic wands, gradually weakening their attack power.

After a hard fight, they finally succeeded in eliminating the dark soldiers and most of the dark magicians at the gate. They walked towards the interior of the castle, which was dark and damp, with a foul smell in the corridor and strange lights flickering on the walls.

In the castle's hall, they saw a huge dark magic circle, on which floated a huge dark magic crystal. This magic crystal exuded a strong dark aura, and was the core of the dark power of the entire castle.

"As long as we destroy this magic crystal, we can completely destroy this dark castle." Lu Fei said.

They walked towards the magic circle, however, when they approached the magic circle, several dark shields suddenly appeared around them, blocking them out.

They tried to use force to break the shield, but the shield was extremely strong. Their attacks only caused ripples on the shield but did not cause any substantial damage.

"This shield is not easy to deal with. We have to find another way." Lu Fei said with a frown.

They began to look for clues in the hall, and after some searching, they found some strange symbols on the pillars of the hall. These symbols were somewhat related to the symbols they had seen in the cave before, and seemed to be the key to cracking the shield.

Lu Fei and Naruto began to study these symbols, trying to find a way to break the shield. During the research, they gradually discovered that these symbols need to be activated with a specific force and sequence to break the shield.

"I think I know how to break the shield." Lu Fei said suddenly. He inserted the Thunder Flame Sword into the ground. The power of the artifact was injected into the ground through the Thunder Flame Sword, resonating with the symbols on the pillar.

Naruto also injected his chakra into the symbol, and according to Lu Fei's instructions, they activated the symbol in a specific order and power. As the symbol was activated, the dark shield slowly disappeared.

They successfully broke the shield and rushed towards the Dark Magic Crystal. 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 immortal law and artifact, flew towards the Dark Magic Crystal 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 castle shook violently under the impact of this force. Cracks began to appear in the walls, and stones on the roof 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 crystal and protect this continent. In the end, their power gradually gained the upper hand, and the dark magic crystal cracked under the powerful attack and then completely shattered.

As the dark magic crystal shattered, the dark castle also collapsed. Lu Fei and Naruto successfully escaped at the last moment when the castle collapsed.
