Naruto Bond

After Lu Fei and Naruto left the secret room, they continued to go deeper into the ruins along the passage. The passage became increasingly quiet, with only the sound of their footsteps echoing in this silent space, as if every step was knocking on the ancient and mysterious door.

As we walked, we saw a wide ice bridge in front of us, which spanned a huge ice valley. The ice valley was bottomless, and we could faintly hear the whistling cold wind coming from below, which was daunting. The ice bridge looked crystal clear, but also a little fragile, as if it could break at any time.

"Be careful, this ice bridge doesn't look very solid." Lu Fei reminded. He was the first to step onto the ice bridge, taking every step carefully and always paying attention to the condition of the ice bridge.

Naruto followed behind, also very cautiously. But just when they reached the middle of the ice bridge, it suddenly shook violently, and then a group of ice-blue flying beasts flew out from the bottom of the ice valley. These flying beasts looked like eagles, covered with hard ice scales, with wings spread out to be several meters wide, their eyes flashed with cold light, and their sharp beaks were like sharp ice blades, swooping down towards Lu Fei and Naruto.

"Not good, get out of the way!" Lu Fei shouted, wielding the Thunder Flame Sword and performing the "Flame Thunder Sky Slash". The flames on the sword intertwined with the power of thunder and lightning, turning into sharp sword energy, slashing at the flying beasts that were swooping down. The sword energy hit the flying beasts, creating sparks on their ice scales, slowing down the flying beasts' swooping momentum, but they quickly adjusted their posture and continued to attack.

Seeing this, Naruto performed the Shadow Clone Technique, and many shadow clones dispersed, some to attract the attention of the flying beasts, while others found the right time to attack the eyes, wings and other vital parts of the flying beasts. The original Naruto quickly formed hand seals on the side, preparing to perform a powerful ninjutsu to counterattack.

"Senjutsu? Wind Style? Nine-tailed Rasenshuriken!" Naruto shouted, and a huge Rasenshuriken appeared in his hand, and he immediately flew towards the densest area of ​​the flying beasts. The Rasenshuriken continued to grow in size during the flight, and the powerful force swept several flying beasts into it. With a violent explosion, the flying beasts were blown to pieces, their feathers (ice scales) flew everywhere, and they fell down screaming.

However, more flying beasts continued to fly up from the bottom of the ice valley. They seemed to feel threatened and attacked more and more frantically. They formed attack formations in the air and charged alternately, making Lu Fei and Naruto overwhelmed.

During the battle, Lu Fei discovered that every time these flying beasts launched a dive attack, when they folded their wings and prepared to fly again, their abdomens would be briefly exposed. The ice scales there were relatively thin and the defense was relatively weak.

"Naruto, attack their abdomen, that's their weak point!" Lu Fei shouted loudly.

After hearing this, Naruto immediately ordered his shadow clones to change the direction of attack and attack the abdomen of the flying beasts. The real Naruto used "Senjutsu? Lava Release? Rasenshuriken", and the high-temperature Lava Release Rasenshuriken with blazing flames accurately hit the abdomen of a flying beast. The ice scales on the abdomen of the flying beast were partially burnt, and the body also swayed and fell down, and it was obviously seriously injured.

Lu Fei took the opportunity to use the "Flame Thunder Demon-Breaking Slash", increasing the power of the Thunder Flame Sword to the extreme, and slashed at the abdomens of other flying beasts with all his strength. The flying beasts were injured and fell one after another under their attack, and the originally dense attack formation was also disrupted.

After a hard fight, they finally repelled all the ice-blue flying beasts. They continued to walk across the ice bridge and came to the other side of the ice valley. In front of them appeared an ice crystal palace shining with mysterious blue light. The architectural style of the palace is extremely unique, with towering spires and gorgeous ice sculptures, which exude an ancient and mysterious atmosphere everywhere.

"This palace looks like the core of the ruins. There must be more important secrets hidden inside." Lu Fei said, he gripped the Thunder Flame Sword tightly and walked towards the palace gate, with Naruto following closely behind him.

The palace gate was tightly closed, and a huge ice scroll was carved on the door. The scroll depicted a grand battle in ancient times, with gods and demons fighting each other, and various powerful forces colliding in the ice and snow. The scene was very shocking. Around the scroll, there were complex runes, which were shining, as if waiting for the opportunity to be triggered to open the door.

They began to study the runes around the gate. After careful observation and exploration, Lu Fei discovered that these runes had similar energy fluctuation patterns to some runes he had seen in the ruins before. So, he tried to inject the power of the Thunder and Flame Sword into some specific key runes according to past experience. Naruto also simultaneously guided his chakra according to a certain pattern.

As power was slowly injected, the runes on the door gradually lit up with brighter light and began to flow in a specific order. Then, there was a dull sound, and the palace door slowly opened. An extremely strong and mysterious power rushed towards him, mixed with a hint of chill, as if it could freeze a person's soul.

Entering the palace, the light inside is relatively bright. The walls are inlaid with huge blue ice crystals, which emit a soft light, illuminating the entire palace. In the center of the palace is a huge ice seat, on which sits a figure wrapped in ice. The face cannot be seen clearly, but the figure exudes a majestic and mysterious aura, as if it has been sleeping here for endless years.

In front of the ice seat, there is an ice platform emitting a blue light, on which is placed a fist-sized ice crystal core. The inside of the crystal core seems to contain all the power sources of this glacial relic. As the light flickers, strands of ice power continue to spread outward, shrouding everything around in this icy force field.

"This crystal core must be the most crucial treasure in this relic. If we can get it, our strength will definitely be able to reach a higher level." Lu Fei said with fiery eyes, but he also knew that getting the crystal core was by no means easy and there would inevitably be many obstacles.

Just as they approached the ice platform, the figure sitting on the ice seat wrapped in the ice suddenly moved. Cracks began to appear in the ice, and a crackling sound was made, as if the existence inside was about to wake up.

Lu Fei and Naruto immediately became alert, stopped, gripped their weapons, and prepared for battle.
