Naruto Bond

Lu Fei and Naruto nimbly dodged the entanglement of the dark vines. The vines twisted quickly on the ground, raising a cloud of dust and splashing sand and gravel wherever they went.

"These vines are endless, we have to find a way to get rid of them!" Naruto shouted with a frown.

While Lu Fei wielded the Thunder Flame Sword to cut off the approaching vines, he observed their movements and soon discovered that these vines were all emerging from the ground under the feet of the black-robed man. The source should be underground where he was standing.

"Naruto, attack the ground under the feet of the man in black robe. That's the source of the vines!" Lu Fei reminded loudly.

After hearing this, Naruto immediately used "Senjutsu? Molten Release? Rasenshuriken", and the high-temperature Molten Release Rasenshuriken flew towards the ground under the feet of the black-robed man. The Rasenshuriken, with blazing flames, accurately hit the target, and a large pit was instantly melted in the ground. The dark vines seemed to have lost their support and stopped gushing out. The vines that had already stretched out also began to wither and collapse to the ground.

Seeing this, the black-robed man became more and more angry. He stomped his staff hard on the ground and chanted a more obscure spell. In an instant, the surrounding space began to distort and deform, and black space cracks appeared. The cracks emitted a strong suction force, trying to suck Lu Fei and Naruto in.

Lu Fei and Naruto quickly stabilized their bodies and exerted their strength to resist the suction. Lu Fei inserted the Thunder Flame Sword into the ground, and the power of the artifact was injected into the ground through the sword, forming a solid energy barrier to resist the suction of the space crack. Naruto performed the Shadow Clone Technique, and many shadow clones held hands and formed a circle, cooperating with Lu Fei's barrier to fight against this sudden danger.

While resisting the suction, Lu Fei noticed that when the man in black robe maintained the space crack, the dark aura around his body would fluctuate briefly, and the most obvious fluctuation was at his back, which might be the weak point of his defense at the moment.

"Naruto, wait until the suction weakens, then we can attack his back together!" Lu Fei shouted.

After a while, as the black-robed man's control of the space crack became a little weaker, the suction gradually weakened. Lu Fei and Naruto saw the right opportunity and exerted their strength at the same time. Lu Fei used "Flame Lightning Slash" and turned into a flame lightning shadow and rushed towards the back of the black-robed man. Naruto used "Senjutsu Super Large Rasengan" and pushed the Rasengan in the same direction.

Their attacks simultaneously hit the weak spot on the back of the black-robed man, who groaned and fell forward, and the space crack disappeared. The black-robed man struggled to stand up, blood oozing from the corner of his mouth, but his eyes still revealed ferocity and unwillingness.

"Don't be too complacent too soon, I am determined to get this crystal ball!" The man in black robe said viciously. He threw away the slightly damaged staff in his hand, quickly formed seals with his hands in the air, and the dark power in his body surged wildly, gradually condensing into a huge phantom of a dark demon behind him.

This demon phantom is tall and has a ferocious face. He holds a huge black sickle in his hand and exudes a terrifying aura, as if he is an evil ghost from the abyss of hell.

"Prepare to die!" The man in black robe roared and commanded the phantom of the dark demon to chop towards Lu Fei and Naruto.

Lu Fei and Naruto did not dare to slack off, as they knew the power of this attack was huge. They looked at each other, understood each other, and decided to use all their strength to deal with it.

Lu Fei raised the Thunder Flame Sword above his head. The flames and lightning power on the sword burned to the extreme. He shouted, "Flame Thunder Overlord Slash - Combine!" The fire thunder power turned into a huge fire thunder dragon, rushing towards the phantom of the Dark Demon.

Naruto also used his strongest move, "Senjutsu? Wind Style? Nine-tailed Rasenshuriken - the power of fusion!" He perfectly combined the Nine-tailed's chakra, senjutsu and his own power to form an extremely huge Rasenshuriken with the power to destroy the world, and followed the Flame Thunder Dragon to attack the Demon God Phantom.

The Flame Thunder Dragon and the Spiral Shuriken collided with the Dark Demon Phantom one after another, and a shocking sound erupted in an instant. The powerful energy shock wave spread in all directions, and the sand and stones on the Gobi Desert were blown into the air, forming a sandstorm that covered the sky and the sun.

In the fierce energy collision, Lu Fei and Naruto gritted their teeth and persisted. They had only one belief in their hearts, that is, they must not let the black-robed man succeed. They must protect the crystal ball and protect this continent.

Gradually, their power began to gain the upper hand. Under the joint attack of the two, the phantom of the Dark Demon became more and more illusory, and finally with a "boom", it completely dissipated. The black-robed man was hit by the backlash of the power, his body was shaken away, and fell heavily to the ground, and there was no movement anymore.

Lu Fei and Naruto stood there tiredly, their bodies covered with scars from the battle, but looking at the crystal ball in their hands that was safe and sound, they showed relieved smiles on their faces.

"Finally got rid of this guy. What secret does this crystal ball hold?" Naruto looked at the crystal ball and asked curiously.

"I'm not sure, but we must not let it fall into the hands of dark forces. We have to find a safe place to study it carefully." Lu Fei said.

After a short rest, they left the Gobi Desert with the crystal ball and headed towards a hidden valley on the mainland.
