Naruto Bond

Lu Fei and Naruto trudged through the windswept Gobi Desert, with flying sand constantly hitting them. Every step they took took a lot of effort, but they kept their eyes fixed as they followed the direction indicated by the mysterious marks.

As we walked, we saw a stone mountain in front of us. The mountain was dark black, as if it had been eroded by the dark forces for a long time. The mountain was full of strange rocks, and it gave off a disturbing atmosphere. And those marks pointed to the entrance of a cave on the mountain.

"It seems that the mysterious treasure may be in this cave." Lu Fei narrowed his eyes and looked at the cave. At the same time, he tightly grasped the Thunder Flame Sword and approached the cave entrance carefully.

Naruto followed behind, also ready for battle. He secretly formed seals with his hands and activated the Sage Mode to prevent any sudden danger from appearing in the cave.

When they stepped into the cave, a pungent stench of decay hit them in the face. The cave was dark and damp, with green phosphorescent lights flickering on the walls, barely illuminating the way forward. The ground under their feet was rugged and uneven, and from time to time some unknown small reptiles crawled quickly, making rustling sounds that made people feel creepy.

Going deeper into the winding passage of the cave, suddenly, many black spikes shot out from the cracks in the cave wall, densely shooting towards them. Lu Fei reacted quickly, waving the Thunder Flame Sword quickly in front of him, forming a light curtain of flames and lightning, blocking the incoming spikes one after another, making a crackling sound.

"Be careful, there are traps everywhere in this cave," Lu Fei warned.

Naruto nodded and used the Shadow Clone Technique, letting the shadow clones explore the way ahead so that they could respond in time if the mechanism was triggered. Sure enough, not long after they walked, the shadow clones sent a message that a trap area full of spikes appeared ahead. The spikes were shining black, and were obviously poisonous.

"I'll lead the way!" Lu Fei said as he inserted the Thunder Flame Sword into the ground. The power of the artifact was transmitted into the ground through the sword body, causing a slight vibration. Many of the spike traps sank, revealing a barely passable path.

They continued along this road and came to a spacious cave hall. In the center of the hall stood a huge stone platform, on which stood a box emitting a strange light. The light exuded a mysterious power, as if attracting them to come closer.

"Could the mysterious treasure be in this box?" Naruto asked curiously.

Just as they were about to approach the stone platform to check, the surrounding ground suddenly surged, and dark sand beasts formed by sand and stone emerged from the ground. These sand beasts were wolves-like, with fierce eyes. Their bodies were made of hard sand and stone, and they looked particularly eerie under the phosphorescent light.

"These guys are here to make trouble again!" Lu Fei frowned, and rushed towards the group of sand beasts first, performing the "Flame Thunder Flash Slash". The Flame Thunder sword energy slashed towards the sand beasts. After hitting the sand beasts, sand and stones flew everywhere, but they quickly re-formed and continued to pounce towards Lu Fei.

Seeing this, Naruto used "Senjutsu Wind Style Nine-tailed Rasenshuriken". A huge spiral shuriken flew towards the densest area of ​​the sand beasts. The powerful force blew away some of the sand beasts, but not long after, they gathered together again.

"It seems that these sand beasts can recover after being dispersed. We have to find their weak points." Naruto shouted.

During the battle, Lu Fei discovered that every time these dark sand beasts re-condensed, a small ball of black energy would flash in their abdomens, which might be their key.

"Naruto, attack their abdomen, that should be their weak point!" Lu Fei reminded loudly.

After hearing this, Naruto immediately ordered his shadow clones to change their attack strategy and attack the abdomens of the sand beasts. The real Naruto used "Senjutsu? Lava Release? Rasenshuriken" and threw it towards the abdomen of a sand beast. The high-temperature Lava Release Rasenshuriken accurately hit the target, and the black energy in the abdomen of the sand beast flashed, and then the entire sand beast collapsed and could never be restored.

Lu Fei also took the opportunity to perform the "Flame Thunder Demon-Breaking Slash", increasing the power of the Thunder Flame Sword to the extreme, and slashed at the abdomen of the other sand beasts with all his strength. One by one, the sand beasts disintegrated under their attack.

After dealing with the dark sand beast, they came to the stone platform and looked at the box emitting strange light in front of them. Lu Fei stretched out his hand to open the box, and the moment he touched the box, a powerful force suddenly surged from the box, knocking both of them back several steps.

"This box has protection, it seems not simple." Lu Fei said after stabilizing his body.

They began to observe the box carefully and found that it was engraved with complex runes. These runes were gleaming and seemed to contain some kind of ancient restriction. After some research, they found that these runes needed to be in a specific order and injected with corresponding power to unlock the restriction.

"I think I know how to open it." Lu Fei said as he inserted the Thunder Flame Sword into the ground and slowly injected his own power into the runes on the box through the sword. At the same time, according to his understanding of those mysterious restrictions in his memory, he guided the power to activate the runes in a specific order.

Naruto also gathered chakra to assist Lu Fei and injected his own power into it. As the runes were lit up one by one, the forbidden light on the box gradually weakened. Finally, the box slowly opened, and a crystal clear crystal ball appeared inside. The crystal ball seemed to contain endless stars, emitting a soft and mysterious light.

"Is this the treasure the dark forces are looking for? I wonder what it can be used for." Naruto said puzzledly while looking at the crystal ball.

Before they could explore further, a powerful energy fluctuation suddenly came from outside the cave, followed by a sinister laugh: "Hahaha, you really found the crystal ball, but it will soon belong to me!"

Lu Fei and Naruto's faces changed, knowing that more enemies were coming. They quickly put away the crystal balls, gripped their weapons, turned around and walked out of the cave.
