Naruto Bond

After Lu Fei and Naruto walked out of the temple with the newly acquired scepter, they continued to head deeper into the jungle. The sunlight shone through the dense branches and leaves, forming patches of light, and the surroundings were filled with the fragrance of flowers and plants and the smell of soil.

Not far away, they heard the sound of gurgling water. Following the direction of the sound, a clear stream appeared in front of them. The stream flowed between the rocks, splashing crystal water. However, just as they were about to approach the stream, ripples suddenly appeared on the water surface, and several water monsters that looked like mermaids but had sharp claws and sharp teeth jumped out of the water.

The hair of these water monsters fluttered like seaweed, and their eyes flashed a strange blue light. They made sharp cries and swam towards Lu Fei and Naruto at an extremely fast speed. The claws in their hands flashed coldly in the sunlight, ready to launch an attack.

Lu Fei reacted quickly, wielding the Thunder Flame Sword and performing the "Flame Thunder Flash Slash". The powerful sword energy slashed at the water monsters, and the sword energy collided with the water surface, splashing water. The water monsters flexibly avoided the attack of the sword energy, then jumped out of the water and grabbed Lu Fei's face with their claws.

Seeing this, Naruto used the Shadow Clone Technique, and several of his shadow clones rushed towards the water monsters and engaged in close combat with them. The real Naruto quickly formed hand seals and prepared to use a powerful ninjutsu. "Senjutsu? Wind Style? Nine-tailed Rasenshuriken!" Naruto shouted, and a huge Rasenshuriken flew towards the group of water monsters. The powerful force caused huge waves in the stream, and several water monsters were caught in it and suffered serious injuries, but they did not retreat, but attacked more frantically.

During the battle, Lu Fei discovered that every time these water monsters launched an attack, a piece of light blue scale would briefly appear on their backs, and the defense there seemed to be relatively weak.

"Naruto, attack the light blue scales on their backs, that's their weak point!" Lu Fei shouted loudly.

After hearing this, Naruto ordered his shadow clones to change the direction of attack and attack the weak spot on the back of the water monster. The real Naruto used "Senjutsu? Lava Release? Rasenshuriken", and the high-temperature Lava Release Rasenshuriken accurately hit the light blue scales on the back of a water monster. The water monster instantly screamed in pain, and its body began to smoke. After struggling for a few times, it sank to the bottom of the water.

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 towards the weak points on the backs of other water monsters. Under their attacks, one water monster after another was injured and sank to the bottom of the water, and the stream gradually returned to calm.

After solving the threat of the water monster, they continued along the stream, hoping to find some deeper secrets about the jungle. As they went deeper, the surrounding scenery became more and more quiet, the trees became taller and denser, and the sunlight could hardly penetrate the layers of branches and leaves, making the ground dark and damp.

Suddenly, a swamp filled with thick fog appeared in front of them. The swamp was filled with a foul smell that made people want to vomit. Lu Fei and Naruto carefully approached the edge of the swamp, trying to find a safe path to pass. However, the swamp seemed to hide some mysterious power. There were constant bubbles of methane coming out, making a "gurgling" sound, as if warning them not to approach easily.

Just as they were hesitating, several huge tentacles suddenly stretched out from the swamp. These tentacles were as thick as pythons, and their surface was covered with disgusting mucus. They quickly rolled towards Lu Fei and Naruto.

Lu Fei immediately wielded the Thunder Flame Sword and performed the "Flame Thunder Sky Slash". The flames on the sword intertwined with the power of thunder and lightning, forming a series of powerful light curtains, trying to cut off the attacking tentacles. However, the tentacles were very powerful, and the light curtains only slightly blocked the tentacles' advance before being easily broken through.

Naruto performed the Shadow Clone Technique, and many of the Shadow Clone Techniques rushed towards the tentacles, some trying to hold the tentacles to restrict their movements, while others looked for opportunities to attack the roots of the tentacles. The real Naruto quickly formed hand seals on the side, preparing to perform a powerful ninjutsu to deliver a heavy blow.

"Senjutsu? Wind Style? Nine-tailed Rasenshuriken!" Naruto once again used a powerful ninjutsu, and a huge Rasenshuriken flew towards the root of the tentacle. The powerful force caused a violent explosion in the swamp, and mud and water were splashed everywhere. The root of the tentacle also suffered a certain degree of damage, and the speed of the attack slowed down slightly.

During the battle, Lu Fei noticed that after each attack of these tentacles, there would be a brief energy fluctuation at the part where they were connected to the swamp, which might be their weak point.

"Naruto, attack the part where the tentacles connect to the swamp. That's the weak point!" Lu Fei shouted.

After hearing this, Naruto ordered his shadow clones to change the direction of attack and attack the vital parts of the tentacles. The real Naruto used "Senjutsu? Molten Release? Rasenshuriken". The high-temperature Molten Release Rasenshuriken with blazing flames accurately hit the part where a tentacle connected to the swamp. The part was instantly melted by the high temperature, and the tentacle collapsed powerlessly in the swamp.

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 at the vital parts of the other tentacles with all his strength. Under their combined attack, the tentacles were cut off one after another, retracted into the swamp, and never appeared again.

After a hard fight, they finally got rid of the danger of the swamp and continued to walk deeper into the jungle. At this time, the sky gradually darkened, the surrounding environment became more gloomy and terrifying, and all kinds of strange sounds echoed in their ears, making people shudder.

They moved forward cautiously, and suddenly, an old and dilapidated castle appeared in front of them. The walls of the castle were covered with moss and vines, and the gates were closed, exuding a mysterious and oppressive atmosphere.

"This castle looks quite old. Maybe there are some secrets hidden inside. Let's go in and take a look." Lu Fei said, with a hint of curiosity and determination in his eyes.

Naruto nodded, and the two walked towards the castle gate. When they approached the gate, the runes on the gate suddenly lit up with a faint light, as if they were examining them. Lu Fei tried to inject the power of the Thunder Sword into the runes on the door, and Naruto also condensed chakra at the same time, guiding the power injection according to a certain rule.

As the power was injected, the rune on the door glowed brighter, and the door slowly opened, letting out an old smell. They walked into the castle, which was dimly lit, with only a few rays of moonlight shining through the broken roof, barely illuminating the way ahead.

The hall of the castle was filled with dust, and there were some tattered tables, chairs and armor placed around. On the walls hung faded portraits with blurred faces of the people in the portraits, as if telling a forgotten history.

They continued to go deeper into the castle and came to a staircase. They walked up the stairs slowly. Every step they took made a creaking sound, which was particularly harsh in the quiet environment.

When they reached the second floor, they suddenly heard a sinister laugh echoing throughout the entire floor. Then, several ghostly figures emerged from the darkness. These ghosts had transparent bodies, emitting a faint blue light. Their eyes were empty, but they revealed an evil aura, floating towards Lu Fei and Naruto.

Lu Fei gripped the Thunder Flame Sword tightly and performed the "Flame Thunder Flash Slash". The sword energy slashed towards the ghost, but the sword energy went straight through the ghost's body without causing any damage.

Naruto used the Shadow Clone Technique, and the shadow clones rushed towards the ghosts, but found that they could not touch them at all. The ghosts easily passed through the bodies of the shadow clones and continued to approach them.

At this critical moment, Lu Fei suddenly remembered that he had read a record about ghosts in an ancient book before. It is said that ghosts are afraid of pure energy and powerful spiritual power.

"Naruto, use your chakra to condense into a pure energy ball and try to see if you can attack them!" Lu Fei shouted loudly.

After hearing this, Naruto immediately began to gather chakra, compressing it into a bright energy ball and throwing it at the ghost. The moment the energy ball came into contact with the ghost, the ghost screamed in pain and its body began to become blurred.

"It works! Keep attacking!" Lu Fei shouted.

Naruto continued to gather chakra, creating more energy balls and attacking the ghosts. Lu Fei also used "Flame Thunder Demon Slash", transforming the power of the sword into pure energy form, and attacked the ghosts together with Naruto.

Under their combined attack, the ghosts' bodies gradually dissipated and eventually disappeared, and peace returned to the second floor of the castle.

They continued to explore the castle, hoping to find something valuable or a clue.
