Naruto Bond

Lu Fei and Naruto continued to search for a suitable sealing place in the mountains with special ore. They walked along the rugged mountain road, and the surrounding environment became more and more dangerous, with steep cliffs and bottomless canyons everywhere.

When they reached the top of a misty mountain, they felt a strong and evil aura surging here. The sky here was always gloomy, with dark clouds and strange lightning flashing from time to time.

"This breath... could it be the clue to the sealed place?" Lu Fei said with a frown. He gripped the Thunder Flame Sword tightly and walked carefully towards the source of the breath.

Naruto followed behind, observing the surroundings vigilantly. When they came to a platform on the mountain, they found a huge dark vortex in the center, which exuded a strong dark aura, as if it was going to swallow everything.

"This should be the core gathering place of the dark forces. We will perform the sealing technique here!" Lu Fei said.

However, just as they were about to set up the seal formation, a group of dark ghosts suddenly emerged from the dark vortex. These ghosts were illusory, emitting a biting cold air, and they pounced towards Lu Fei and Naruto with their fangs and claws.

"Damn you, you're here to make trouble again!" Naruto quickly formed seals with both hands and used the Shadow Clone Technique. Many shadow clones fought fiercely with the dark ghosts, trying to prevent them from approaching Lu Fei.

Lu Fei wielded the Thunder Flame Sword and performed the "Flame Thunder Holy Spirit Slash". A stream of Flame Thunder Sword Qi containing divine power slashed at the dark ghosts. Wherever the sword Qi reached, the dark ghosts screamed in pain and their bodies gradually dissipated.

But the dark ghosts continued to pour out of the dark vortex, seemingly endless. During the battle, Lu Fei discovered that the actions of these dark ghosts seemed to be controlled by some kind of power at the center of the dark vortex. As long as the core control power was destroyed, the ghosts could be stopped from pouring out.

"Naruto, let's attack the center of the dark vortex first!" Lu Fei shouted loudly.

After hearing this, Naruto immediately ordered his shadow clones to restrain the dark ghost, while the real Naruto used "Senjutsu? Lava Release? Rasenshuriken" and threw it towards the center of the dark vortex.

The Lava Rasenshuriken carried high-temperature lava and accurately hit the center of the dark vortex. The rotation speed of the dark vortex slowed down instantly, and the outflow of dark ghosts became sparse.

Lu Fei took the opportunity to perform "Flame Thunder Devil Slash". He increased the power of the Thunder Flame Sword to the extreme and slashed at the center of the dark vortex with all his strength. This sword contained a powerful force and successfully destroyed the center of the dark vortex, and the dark ghosts also dissipated.

After resolving the interference of the dark ghost, they began to formally arrange the sealing array. Lu Fei placed the special ore in a specific position according to the records in the golden book, and then carved complex runes on the ground with the Thunder Flame Sword. Naruto gathered chakra on the side and injected his power into the runes to assist Lu Fei in completing the arrangement of the sealing array.

After some effort, the sealing array was finally set up. They stood at the edge of the sealing array, completely integrating the power of the artifact with their own power, and prepared to perform the sealing technique.

"Let's start!" Lu Fei shouted.

They formed seals with their hands, chanted something, and performed a powerful sealing technique. A dazzling light shot out from their hands and flew towards the core of the dark power. Wherever the light went, the dark aura was gradually dispelled, and the dark power began to be sealed into the formation.

However, just as the seal was about to be completed, the dark forces suddenly erupted with a powerful resistance force. This force impacted the seal array, causing cracks to appear in the seal array and the light began to flicker.

"Oh no, it's resisting, we can't let the seal fail!" Naruto shouted.

They increased their power output, trying to suppress the resistance of the dark forces. Lu Fei inserted the Thunder Flame Sword into the seal array, and the power of the artifact was continuously injected into the array to stabilize the structure of the seal array. Naruto used the "Senjutsu Super Large Rasengan" to integrate the Rasengan into the seal light and enhance the power of the seal.

With their efforts, the cracks in the seal were gradually repaired, and the light became bright again. The resistance of the dark power became weaker and weaker, and was finally completely sealed in the seal.

As the dark power was sealed, the sky at the top of the mountain gradually became clear again, and the sun shone on them, bringing the long-lost warmth.

"Finally succeeded, the dark power in this area has finally been sealed!" Naruto said happily.

"Well, but this is only temporary. We still need to find other sources of dark power on this continent and seal them one by one." Lu Fei said.

They left the top of the mountain exhausted and relieved.
