Naruto Bond

Lu Fei and Naruto continued to move forward along the passage deep in the ruins. The passage became narrower and narrower, and from time to time sand and stones fell from the top of their heads, making rustling sounds, which seemed particularly abrupt in this quiet environment.

Soon, they came to a relatively open hall. The dome of the hall was very high and inlaid with some glimmering gems, which made the whole hall look like a dream. In the center of the hall stood a huge stone platform, on which stood an ancient hourglass. The upper part of the hourglass was filled with golden sand, which emitted a soft light, as if it contained a mysterious and powerful force, and was slowly flowing down.

"This hourglass doesn't look simple. Maybe it is the most important treasure in these ruins." Lu Fei said as he approached the stone platform cautiously. Naruto followed closely behind him, carefully observing the appearance of the hourglass and the surrounding situation.

Just as they approached the stone platform, the air around them seemed to freeze in an instant, and then, from every corner of the hall, sand phantoms emerged. These phantoms were human-like in shape, but were made up of flowing sand. Their faces were blurry, with only a pair of eyes emitting a cold light. They held sand weapons, including swords and spears, and surrounded Lu Fei and Naruto.

"Be careful, there are new enemies!" Lu Fei shouted, and took the lead in wielding the Thunder Flame Sword, performing the "Flame Thunder Sky Slash". The flames on the sword intertwined with the power of thunder and lightning, turning into a series of light curtains, trying to block the sand phantoms rushing over. However, the sand phantoms passed through the light curtains, as if they were not affected, and continued to rush towards them, stabbing and slashing at them with the sand weapons in their hands.

Seeing this, Naruto used the Shadow Clone Technique, and many of the Shadow Clone Techniques rushed towards the Sand Phantoms, fighting them in close combat, trying to disrupt their attack rhythm. The real Naruto quickly formed hand seals on the side, preparing to use a powerful ninjutsu to counterattack.

"Senjutsu? Wind Style? Nine-tailed Rasenshuriken!" Naruto shouted, and a huge Rasenshuriken appeared in his hand, and immediately flew towards the densest area of ​​the Sand Phantoms. The Rasenshuriken continued to grow in size during the flight, and the powerful force swept a piece of Sand Phantoms into it. With a violent explosion, the Sand Phantoms were blown apart and turned into dust again, floating in the air.

But before they could breathe a sigh of relief, the scattered sand and dust quickly gathered together again, forming sand phantoms again, and there were more of them than before. They rushed towards Lu Fei and Naruto again, and the attack became more and more fierce.

During the battle, Lu Fei discovered that every time these sand phantoms launched an attack, there would be a brief energy fluctuation in the part of their bodies connected to the weapons. That might be their weak point. As long as this part was destroyed, they might be able to completely dissipate.

"Naruto, attack the place where their bodies and weapons are connected, that's the weak point!" Lu Fei shouted loudly.

After hearing this, Naruto immediately ordered his shadow clones to change the direction of attack and attack the part where the Sand Phantom's body and weapon were connected. The real Naruto used "Senjutsu? Molten Release? Rasenshuriken", and the high-temperature Molten Release Rasenshuriken with blazing flames accurately hit the part where the Sand Phantom's body and weapon were connected. After the part where the phantom's body and weapon were connected was hit, chaotic energy fluctuations appeared instantly, and then the entire phantom dissipated with a bang, and never re-condensed.

Lu Fei took the opportunity to perform the "Flame Thunder Demon-Breaking Slash", increasing the power of the Thunder Flame Sword to the extreme, and slashed with all his strength at the parts where the bodies and weapons of the other Sand Phantoms were connected. Under their attack, the Sand Phantoms dissipated one by one, and finally disappeared completely, and the hall returned to peace.

"Huh, we finally got rid of these troublesome guys. Let's see what this hourglass has." Lu Fei said as he wiped the sweat from his forehead.

They walked to the stone platform and looked at the hourglass carefully, and found that it was engraved with complex runes. These runes flickered, and seemed to echo with the golden sand in the hourglass. Moreover, the arrangement of the runes had a certain pattern, as if telling some ancient secret.

Just as Lu Fei reached out to touch the hourglass, a powerful force suddenly surged out of the hourglass, knocking both of them back several steps.

"This hourglass is protected. It seems not so easy to get it." Lu Fei said after stabilizing his body.

They began to study the runes around the hourglass. Relying on past experience in breaking the ban and his understanding of the mysterious power, Lu Fei tried to inject the power of the Thunder and Flame Sword into some key runes in a specific order. Naruto also condensed chakra at the same time and guided the power into the runes according to the corresponding rules.

As power was slowly injected, the runes on the hourglass gradually lit up with brighter light and began to flow in a new order. The golden sand that was originally flowing downwards also stopped flowing, and the force that repelled them around them gradually weakened.

"It seems to be working. Let's try harder!" Lu Fei said, continuing to increase the amount of strength he injected.

After some effort, the runes on the hourglass glowed brightly, followed by a soft humming sound, and the protective force completely disappeared, and the golden sand returned to its normal flow. Lu Fei carefully picked up the hourglass, and it was warm in his hand. He could clearly feel a majestic and mysterious power contained in it, as if this power could control time and space.

"The power of this hourglass seems to be very strong, but I'm not sure how to use it exactly." Naruto said curiously.

"Well, let's put it away first, and then look for it in these ruins to see if there are any relevant records to find out its use." Lu Fei responded.

They put away the hourglass and searched around the hall carefully. As expected, they found an ancient mural on the wall of one side of the hall. The mural depicted someone holding an hourglass and performing various magical powers. Some of them seemed to have stopped time and made everything around them stand still; some of them opened a space channel and moved to another place instantly. There were also some ancient text annotations next to it. Although it was a bit difficult to interpret, they still roughly understood some basic uses of the hourglass.

"So that's how it is. This hourglass is really a powerful treasure. It might come in handy at a critical moment in the future." Lu Fei said excitedly.

"Yeah, then we have to take good care of it." Naruto nodded in agreement.

Carrying the hourglass, they continued to explore deeper into the ruins.
