Naruto Bond

Following the clues in the diary, Lu Fei and Naruto headed towards the unknown dark nest deep in the mountains. The journey became more and more dangerous, the biting cold wind blew across their faces like a blade, the road under their feet became slippery and difficult to walk, and from time to time loose rocks rolled down the cliff, making bursts of roars.

They came to a narrow mountain stream with steep cliffs on both sides, almost blocking the sky. Just as they were crossing carefully, suddenly, a sharp whistle echoed in the mountain stream. Then, countless black spikes shot towards them from the cliffs like raindrops.

"Be careful!" Lu Fei shouted, and the Thunder Flame Sword danced quickly, forming a shield of flames and lightning in front of him. The spikes hit the shield, splashing sparks and being bounced away one after another.

Naruto also used the Shadow Clone Technique, and the shadow clones dispersed, some helped Lu Fei resist the spikes, and some rushed in the direction of the spikes, trying to find the source of the attack. The real Naruto quickly formed hand seals on the side, preparing to use a powerful ninjutsu to counterattack.

"Senjutsu? Wind Style? Rasenshuriken!" Naruto shouted, and a huge Rasenshuriken flew towards the cliff on one side of the mountain stream. The Rasenshuriken grew larger as it flew, and its powerful force shattered the rocks on the cliff, causing a small landslide.

In the dust of the landslide, a huge dark pangolin slowly emerged. The pangolin was covered with black scales, each scale flashing with a strange light, its eyes were like two burning flames, and its huge claws left deep marks on the ground.

"So it was this monster that was causing trouble." Lu Fei said, he clenched the Thunder Flame Sword and rushed towards the Dark Pangolin. "Flame Lightning Slash!" The flame and lightning power on the Thunder Flame Sword burst out instantly, and a stream of Flame Lightning Sword Qi slashed towards the Pangolin.

The dark pangolin was not in a hurry. It curled up its body and raised its scales to form a solid defense ball. The flame and lightning sword energy hit the scale defense ball, leaving only a shallow mark on it.

Seeing this, Naruto used "Senjutsu? Molten Release? Rasenshuriken" and threw it towards the pangolin's abdomen. The high-temperature Molten Release Rasenshuriken, with blazing flames, accurately hit the relatively weak part of the pangolin's abdomen. The pangolin let out a painful roar, the scales on its abdomen were scorched, and its body unfolded from the defensive ball state.

Lu Fei took the opportunity to perform the "Flame Thunder Demon Slash". He increased the power of the Thunder Flame Sword to the extreme and slashed at the pangolin's head with all his strength. This sword contained great power and successfully left a deep wound on the pangolin's head.

The dark pangolin was enraged, and it opened its bloody mouth and spurted out a stream of black mucus. Wherever the mucus went, the ground was corroded into large pits, emitting a pungent smell.

Lu Fei and Naruto dodged quickly, knowing that they had to find the fatal weakness of the dark pangolin as soon as possible in order to defeat it completely. During the battle, Lu Fei discovered that when the pangolin sprayed mucus, there would be a brief energy fluctuation at the base of its tail, which might be its weak spot.

"Naruto, attack the base of its tail!" Lu Fei shouted.

After hearing this, Naruto immediately ordered his shadow clones to restrain the Dark Pangolin, while the real Naruto used the "Senjutsu - Super Large Jade Rasengan" and threw it towards the base of the pangolin's tail.

The super-large Rasengan accurately hit the base of the pangolin's tail. The pangolin let out a shrill scream. A huge wound appeared at the base of the tail where it was hit, and black blood gushed out.

Lu Fei took the opportunity to perform the "Flame Thunder Final Slash". He increased the power of the Thunder Flame Sword to the extreme and slashed at the pangolin's heart with all his strength. This sword contained a powerful force and successfully pierced the heart of the dark pangolin. The huge body of the dark pangolin fell down with a bang, creating a huge deep pit in the mountain stream.

They continued to move forward in the mountains, following the clues in the diary, and came to a valley shrouded in dark fog. The valley was filled with a strong stench that made it difficult to breathe.

"This is near the lair of the dark forces, everyone be careful." Lu Fei said, looking around vigilantly. The light on the Thunder Flame Sword seemed particularly dazzling in the dark mist.

Naruto was also ready for battle, and he secretly formed seals with his hands, turning on the Sage Mode. They slowly walked into the valley, and suddenly, a group of dark knights emerged from the dark mist. These knights were covered in black armor, with only a pair of flashing red eyes on their helmets. They rode black war horses, holding sharp spears in their hands, and exuded a strong dark aura.

"Prepare for battle!" Lu Fei shouted, and he rushed towards the group of dark knights first. As the Thunder Sword was swung, the power of the Thunder and Flame collided with the spears of the dark knights, making a series of metal collision sounds.

Naruto used the Shadow Clone Technique, and many of his Shadow Clone Techniques fought fiercely with the Dark Knight. The real Naruto gathered his chakra aside, ready to use a powerful ninjutsu to deliver a fatal blow.

During the battle, Lu Fei discovered that although the attacks of these dark knights were fierce, there seemed to be some loopholes in their coordination. As long as he could find the flaws in their coordination, he could defeat them one by one.

"Naruto, pay attention to the flaws in their coordination and attack their gaps!" Lu Fei shouted loudly.

After hearing this, Naruto immediately ordered his shadow clones to observe the coordination of the Dark Knights and look for opportunities to attack. The real Naruto used "Senpo? Wind Style? Nine-tailed Rasenshuriken" and threw it towards the place where the coordination of the Dark Knights was flawed.

The spiral shuriken continued to grow larger during its flight, and its powerful force knocked the dark knights away one after another, disrupting their attack rhythm.

Lu Fei took the opportunity to perform the "Flame Thunder Tyrant Slash". He increased the power of the Thunder Flame Sword to the extreme and slashed at a more prominent knight in the group of dark knights with all his strength. This sword contained a powerful force and successfully cut the knight and his horse into two pieces.

The other dark knights saw their companions being defeated, but did not retreat, but attacked more frantically. They formed a tight encirclement, trying to trap Lu Fei and Naruto in the middle.

Lu Fei and Naruto cooperated with each other and continued to fight against the Dark Knights. They continued to use powerful attack methods and gradually gained the upper hand. After a hard fight, they finally eliminated all the Dark Knights.

As the dark knight fell, the dark fog in the valley gradually dissipated, and they saw a huge dark castle in front of them. The walls of the castle were towering into the clouds, and the walls were covered with various evil runes and statues, exuding a strong dark atmosphere.

"This is the lair of the dark forces, let's go in!" Lu Fei said, he gripped the Thunder Flame Sword tightly and walked towards the castle.
