Naruto Bond

As the powerful dark aura surged in, the entire castle seemed to be shaking, stones on the walls fell off, and a cloud of dust was raised.

Lu Fei and Naruto were on high alert. They could feel that the dark power they were facing this time was far greater than before. A figure in a black robe slowly walked out from the depths of the castle. Under the black robe, one could not see his face, but only a pair of eyes emitting cold purple light. The eyes were full of evil and tyranny, as if they wanted to devour all the beauty in the world.

"You two are so stupid, you dare to ruin my plans again and again. Today is the day you die!" The black-robed figure made a low and hoarse voice. As soon as he finished speaking, the air around him instantly became bitterly cold. Black energy tentacles emerged from the ground and quickly spread towards Lu Fei and Naruto. Wherever they passed, the ground was corroded with black marks.

Lu Fei immediately used the "Flame Lightning Slash". The flames on the sword intertwined with the power of thunder and lightning, turning into extremely sharp sword energy, slashing at those black energy tentacles. The sword energy collided with the tentacles, making a sizzling sound, and black smoke spread out, but those tentacles continued to rush towards them crazily.

Naruto also used the Shadow Clone Technique, and many of his shadow clones rushed towards the tentacles, trying to use their bodies to block their approach. The real Naruto quickly formed hand seals on the side, preparing to use a powerful ninjutsu to deliver a heavy blow.

"Senjutsu? Wind Style? Nine-tailed Rasenshuriken!" Naruto shouted, and a huge Rasenshuriken appeared in his hand, and immediately flew towards the black-robed figure. The Rasenshuriken continued to grow larger during the flight, and the powerful force brought a gust of wind, whistling towards the target.

The black-robed figure just waved his hand lightly, and a black light curtain appeared in front of him. The spiral shuriken hit the light curtain, causing only a ripple of energy before being easily blocked.

During the fierce confrontation, Lu Fei carefully observed the black-robed figure's every move and discovered that every time it cast magic for defense or attack, a faint energy fluctuation would flicker at the cuffs of its black robe. That might be the key to its hidden power, but also its weakness.

"Naruto, attack the cuffs, that's the weak point!" Lu Fei shouted.

After hearing this, Naruto immediately ordered his shadow clones to change the direction of attack and attack the cuffs of the black-robed figure. The real Naruto used "Senjutsu? Lava Release? Rasenshuriken", and the high-temperature Lava Release Rasenshuriken with blazing flames accurately hit the cuffs of the black-robed figure.

After the cuff of the black-robed figure was hit, chaotic energy fluctuations instantly appeared there, and a hole was burned in the black robe. It let out an angry roar, and the originally orderly attack became a little panicked.

Lu Fei took the opportunity to perform "Flame Thunder Demon Slash", increasing the power of the Thunder Flame Sword to the extreme, and slashed at the weak part of the black-robed figure's sleeves with all his strength. This sword contained a powerful force, and the black-robed figure could not dodge and was hit by the sword energy. His body retreated a few steps, and the black robe on his body was torn even more severely, revealing the dry body inside.

“Damned ants, you’ve completely pissed me off!” The black-robed figure roared, and began to quickly form seals with his hands, muttering something. The dark aura around him became increasingly dense, as if it was going to turn the entire space into a dark abyss.

Suddenly, a group of dark ghosts emerged from around its body. These ghosts had different shapes, some with bared fangs and claws, some making shrill screams, and all pounced towards Lu Fei and Naruto.

Lu Fei wielded the Thunder Flame Sword and performed the "Flame Thunder Sky Slash", forming a series of light curtains to try to block the ghost's approach. Naruto performed the Shadow Clone Technique, letting the shadow clone fight the ghost in close combat, while the real Naruto continued to look for opportunities to perform powerful ninjutsu again.

In the process of fighting with the ghosts, Lu Fei discovered that every time these dark ghosts passed through a physical attack, energy flashes would briefly appear on their heads, which should be their weak points.

"Naruto, attack the ghosts' heads, that's their weak spot!" Lu Fei shouted.

After hearing this, Naruto ordered his shadow clones to change their attack direction and attack the dark ghost's head. The real Naruto used the "Senjutsu Super Large Rasengan" and threw it towards the densest area of ​​the ghost group. After the Rasengan hit the ghost's head, the ghosts instantly dissipated and turned into wisps of black smoke.

With their combined attack, the dark ghosts were gradually wiped out, but the black-robed figure took advantage of this gap to prepare powerful dark magic.

It just waved its hands, and a huge dark beam shot towards Lu Fei and Naruto. The dark power contained in this beam was extremely powerful, as if it could crush everything.

Lu Fei and Naruto did not flinch at all. They increased their strength to the limit. Lu Fei used the "Phantom Star Sword Technique" (a powerful sword technique he had acquired before) to instantly create multiple sword shadow clones in front of him, and they slashed at the dark beam together. Naruto used a new ninjutsu that was a fusion of "Senjutsu? Wind Release? Nine-tailed Rasenshuriken" and "Senjutsu? Melt Release? Rasenshuriken", which was more powerful than before.

The two powerful forces collided with the dark beam, and a dazzling light burst out in an instant. The entire castle was shaken by the impact of this energy, and the walls began to collapse on a large scale, with rubble flying everywhere.

In the light and smoke, Lu Fei and Naruto gritted their teeth and tried their best to maintain the attack. They knew that if they relaxed, all their efforts would be wasted and the dark forces would completely ravage the continent.

Finally, after a difficult stalemate, their power gradually gained the upper hand, and the dark beam was pushed back little by little, and finally dissipated completely. The black-robed figure also consumed a lot of dark power, and his body became illusory and shaky.

"Now, Naruto, let's go together!" Lu Fei shouted.

They seized this rare opportunity and rushed towards the black-robed figure at the same time. Lu Fei used "Flame Thunder Demon Slash" and Naruto used "Senjutsu Super Jade Rasengan". The two attacks hit the black-robed figure at the same time. With a scream, the black-robed figure exploded and turned into countless dark fragments, completely dissipating in the air.

With the death of the black-robed figure, the dark atmosphere in the castle quickly faded, and the sun once again shone through the ruins of the castle. Lu Fei and Naruto sat on the ground exhausted. Although they were exhausted at the moment, they had a gratified smile on their faces, because they successfully prevented a major conspiracy of the dark forces and took another solid step towards protecting the peace of the continent.

After a short rest, they stood up and prepared to leave the dilapidated castle and continue exploring other unknown places in the forest.
