Naruto Bond

As the crackling sound continued, more and more cracks appeared on the ice, and finally it peeled off like a broken eggshell, revealing the appearance of a tall ice guardian. It exuded a biting coldness, its skin was like crystal clear ice, and its eyes were like deep ice abysses, revealing a cold and majestic light. It was wearing a set of exquisite ice armor that exuded a faint blue halo, and in its hand was a giant ice sword, with runes flowing on the sword body, as if condensing endless ice power.

"Anyone who trespasses into the Ice Crystal Palace will die!" The Ice Guardian made a low and cold voice. As he spoke, the temperature around him dropped sharply. A thick layer of ice instantly condensed on the ground and spread towards Lu Fei and Naruto.

Seeing this, Lu Fei took the lead in launching an attack, performing the "Flame Lightning Slash". The flames and lightning power on the Thunder Flame Sword were particularly dazzling in this icy environment, and sword energy slashed towards the Ice Guardian. The sword energy collided with the ice layer in front of the Ice Guardian, splashing large pieces of ice flowers. Although it slightly slowed down the speed of the ice layer spreading, the Ice Guardian was unharmed and continued to walk towards them steadily.

Naruto did not dare to delay and performed the Shadow Clone Technique. Many shadow clones rushed towards the Ice Guardian, trying to interfere with its actions. The real Naruto quickly formed hand seals on the side, preparing to perform 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 Ice Guardian. The Rasenshuriken continued to grow in size during the flight, and the powerful force made the surrounding air seem to be stirred and twisted. However, when the Rasenshuriken hit the Ice Guardian, it only left a shallow scratch on its ice armor, and then it was bounced away by the icy power gushing out of the Ice Guardian.

The Ice Guardian snorted coldly, swung the ice sword in his hand, and swept towards the shadow clones. Wherever he went, the shadow clones were instantly frozen, and then turned into ice chips and dissipated in the air. It moved very quickly, and in the blink of an eye it attacked Lu Fei and Naruto's real body again, swung the ice sword, and a huge ice blade fell towards them. Wherever the ice blade passed, the space seemed to be frozen, with a momentum of destroying the world.

Lu Fei and Naruto quickly jumped to the sides and narrowly avoided the attack. While dodging, Lu Fei noticed that every time the Ice Guardian swung its ice sword to attack, there would be a brief energy fluctuation at the joints of its shoulders and elbows. The connection of the ice armor there seemed to be less tight than other places, which might be its weak point.

"Naruto, attack the shoulder and elbow joints, those are its weak points!" Lu Fei shouted.

After hearing this, Naruto immediately ordered the remaining shadow clones to change the direction of attack and attack the shoulder and elbow joints of the Ice Guardian. The real Naruto used "Senjutsu? Molten Release? Rasenshuriken", and threw the high-temperature Molten Release Rasenshuriken with blazing flames at the shoulder and elbow joints on one side of it.

The Molten Release Rasenshuriken hit the target accurately. After the Ice Guardian's shoulder and elbow joints were hit, cracks appeared in the ice armor, and a trace of cold air leaked out from the cracks. Its movements also slowed down for a moment, and the rhythm of the attack was disrupted. Lu Fei took the opportunity to perform "Flame Thunder Demon Breaker", increasing the power of the Thunder Flame Sword to the extreme, and slashed at the joints of the other shoulder and elbow with all his strength, successfully breaking part of the ice armor at the two places, and the Ice Guardian's movements became more rigid.

The Ice Guardian was enraged. It chanted an ancient ice spell and the surrounding space was instantly filled with frost. Countless sharp ice cones shot towards Lu Fei and Naruto from all directions. At the same time, thick icicles emerged from the ground, trying to trap them.

Lu Fei wielded the Thunder Flame Sword and performed the "Flame Thunder Sky Slash", forming a light curtain of flames and lightning in front of him, blocking the incoming ice cones one after another. The ice cones hit the light curtain and instantly turned into ice mist and dissipated. Naruto performed the "Senjutsu Super Large Rasengan" and smashed it towards the approaching ice pillars. The powerful force contained in the Rasengan shattered the ice pillars one after another, opening up a temporary escape route for them.

But the Ice Guardian did not stop its attack. It inserted the ice sword into the ground, and more ice layers gushed out from underground and swept towards them. These ice layers also contained powerful confining forces. Once they were wrapped up, it would be difficult to break free.

"We have to find a way to get close and interrupt its spellcasting, otherwise this will go on endlessly!" Lu Fei shouted.

The two looked at each other, and they understood each other's intentions, and rushed towards the Ice Guardian at the same time. As they approached, they dodged the ice layer and endured the attacks of the ice cones, but they still had no intention of retreating.

When approaching the Ice Guardian, Lu Fei used "Flame Thunder Tyrant Slash", and the power of the Thunder Flame Sword turned into a huge flame and thunder sword energy, slashing towards the head of the Ice Guardian. Naruto used "Senjutsu? Melting Release? Rasenshuriken" and threw it towards the chest of the Ice Guardian, trying to give it a fatal blow.

The Ice Guardian sensed the crisis, and hurriedly raised its ice sword to block Lu Fei's sword energy, while dodging Naruto's Rasenshuriken by moving sideways. However, it was still hit by the Rasenshuriken, and several more cracks appeared on its ice armor, and its body shook a few times.

Taking advantage of this opportunity, Lu Fei once again used the "Flame Thunder Final Slash" and slashed at the Ice Guardian's leg joint. The Ice Guardian's leg was injured and he knelt on one knee, but there was still ferocity and unwillingness in his eyes, and he struggled to stand up and fight back again.

Naruto seized the opportunity and used "Senjutsu Wind Style Nine-tailed Rasenshuriken - Power of Fusion" to fuse his strongest powers together to form an extremely huge Rasenshuriken with the power to destroy the world, and threw it towards the head of the Ice Guardian.

This time, the spiral shuriken accurately hit the Ice Guardian's head. The powerful force directly shattered the ice armor on its head. The Ice Guardian let out a shrill scream, and its huge body fell to the ground, completely losing its life. The surrounding ice layers and ice cones also stopped attacking and began to slowly dissipate.

"Huh, we finally got rid of this big guy. Let's go get the crystal core." Lu Fei said, wiping the sweat from his forehead.

They walked quickly to the ice platform and looked at the ice crystal core that was emitting azure light. Lu Fei reached out and carefully picked up the crystal core. It was freezing cold, but he could clearly feel the majestic and pure power of ice in it, as if he was holding the core soul of this glacial relic in his hand.

"With this crystal core, we will be more confident when facing various ice-attribute dangers in the future, and maybe we can use it to develop some new ways to use our power." Naruto said excitedly.

"Well, let's put it away first, and then we'll look around in this palace to see if there are any other useful things. Then we'll leave these ruins. We don't know what the situation is outside now." Lu Fei responded.

They collected the ice crystal core and searched the palace carefully again. They found some ancient scrolls that recorded the mysteries of ice and several small ornaments with the power of ice. Although they were not particularly precious compared to the crystal core, they still had a certain value, so they were collected as well.

After everything was ready, they left the Ice Crystal Palace along the original route and walked out of the glacial ruins full of mystery and danger.
