Naruto Bond

After successfully destroying the powerful evil spirit, Lu Fei and Naruto did not stop. They continued to patrol the world of Demon Slayer to ensure that no new evil spirits appeared to threaten people's safety.

However, the peaceful days did not last long. One day, while Lu Fei and Naruto were on patrol, they suddenly felt an extremely evil aura coming from afar. This aura was strong and strange, which made them feel a little uneasy.

"Naruto, this aura is not right, we have to go and take a look." Lu Fei said.

Naruto nodded, "Well, maybe it's another powerful demon."

They followed the direction of the smell and came to a mysterious valley they had never been to before. The valley was filled with thick black fog, making it difficult to see what was inside.

"Be careful, Lu Fei, it feels dangerous here." Naruto said warily.

Lu Fei formed seals with his hands, ready to respond to any possible attacks at any time, "Well, you should pay attention too."

When they stepped into the valley, the surrounding fog suddenly surged and formed strange shapes.

"What the hell is this?" Naruto frowned.

Lu Fei observed his surroundings and said, "I don't know, but it's definitely not a good sign."

Just then, a sinister laugh came from the fog, "Hahahaha, you are finally here."

Lu Fei and Naruto looked at each other, "Who is it? Come out!"

As the laughter stopped, a figure slowly walked out of the mist. This was a mysterious man with a black aura all over his body, and his eyes flashed with strange light.

"You don't need to know who I am. You just need to know that today is the day you die." said the mysterious man.

Naruto shouted angrily: "Stop talking nonsense, come and try if you have the guts!"

The mysterious man sneered and waved his hands. The surrounding mist instantly turned into countless sharp blades, shooting towards Lu Fei and Naruto.

Lu Fei used the Ten-Tails Shield to block the sharp blades.

Naruto took the opportunity to rush towards the mysterious man, "Rasengan!"

The mysterious man dodged sideways, then swung his hand back, and a powerful force knocked Naruto back.

"This guy is very strong!" said Naruto.

Lu Fei said: "Let's go together!"

The two of them attacked at the same time and started a fierce battle with the mysterious man.

The mysterious man's attack methods are endless and powerful, and Lu Fei and Naruto gradually fall into trouble.

"We can't go on like this. We have to find his weakness." Lu Fei said.

Naruto attacked while observing the mysterious man's movements.

Suddenly, Naruto noticed that every time the mysterious man attacked, there would be a brief pause in his right shoulder area.

"Lu Fei, attack his right shoulder!" Naruto shouted.

Lu Fei understood what Naruto meant and focused his strength to attack the mysterious man's right shoulder.

The mysterious man didn't expect that they would discover his weakness, and was hit by Lu Fei's attack, and screamed in pain.

Naruto took the opportunity to launch another attack, "Senjutsu: Super Large Rasengan!"

The mysterious man was hit by this powerful attack and fell to the ground.

However, he did not die, but stood up again, and the aura on his body became even more evil.

"Do you think you can defeat me like this? You are too naive!" said the mysterious man.

A powerful force suddenly burst out from his body, knocking Lu Fei and Naruto away.

Lu Fei and Naruto got up from the ground with serious expressions.

"Who is this guy?" Naruto said.

Lu Fei thought for a moment, "No matter who he is, we can't back down."

At this moment, the mysterious man made seals with his hands and muttered something.

Suddenly, a huge magic circle appeared in the valley, and countless evil spirits poured out of the magic circle.

"Oh no, it's an army of evil spirits!" Lu Fei said.

Naruto looked at the army of demons in front of him, "It looks like this is going to be a fierce battle."

Lu Fei and Naruto showed no fear at all. They rushed into the army of evil spirits and started a fierce battle.

Lu Fei used the power of the Ten-Tails, and wherever the purple light went, evil spirits fell down one after another.

Naruto was not to be outdone. In Nine-Tails mode, each of his attacks was powerful and smashed the evil spirits to pieces.

But the number of evil spirits increased, as if endless.

"This is not a solution. We must get rid of that mysterious man first." Lu Fei said.

Naruto nodded, "Okay, I'll clear the way, and you take the opportunity to attack him."

Naruto used a powerful attack to open a path for Lu Fei, and Lu Fei took the opportunity to rush towards the mysterious man.

The mysterious man saw Lu Fei rushing over and attacked again.

Lu Fei dodged flexibly and finally approached the mysterious man.

"Ten-Tails Ultimate Explosion!" Lu Fei used all his strength to launch the strongest attack.

The mysterious man was hit by this powerful force and his body began to collapse.

With the death of the mysterious man, the magic circle disappeared and the army of evil spirits stopped moving.

"Finally solved." Lu Fei breathed a sigh of relief.

Naruto said, "But I don't know if there will be any new threats."

Just as they were about to leave the valley, a crack suddenly appeared in the sky.

A huge figure walked out from the crack. It was the king of evil spirits with terrifying power.

"Do you think this is the end?" said the King of Evil Spirits.

Lu Fei and Naruto looked at the Demon King with shock in their hearts.

"This guy's aura is stronger than any previous one!" Lu Fei said.

Naruto said, "No matter what, we must fight to the end!"

The Demon King laughed, "Just you guys?"

He waved his hand and sent out a powerful wave of energy, attacking Lu Fei and Naruto.

Lu Fei and Naruto quickly dodged.

"We can't let him keep attacking," Naruto said.

They both rushed towards the Demon King at the same time.

The Demon King easily fended off their attacks.

"Too weak, too weak!" the Demon King laughed.

Lu Fei and Naruto did not give up. They kept looking for the weakness of the Demon King.

During the fierce battle, Lu Fei discovered that there was a special rune under the feet of the Demon King.

"Naruto, attack the runes under his feet!" Lu Fei shouted.

Naruto heard Lu Fei's hint and concentrated his strength to attack the rune.

The Demon King sensed their intentions and tried to stop Naruto.

Lu Fei took the opportunity to launch an attack and restrain the King of Evil Ghosts.

Naruto successfully hit the rune and the demon king roared in pain.

"Now!" Lu Fei and Naruto launched their strongest attacks at the same time.

The King of Evil Ghosts was finally destroyed under their attack.

With the death of the Demon King, the crack in the sky disappeared.

Lu Fei and Naruto fell to the ground exhausted.

"It's finally over..." Naruto said.

Lu Fei looked at the sky and said, "I hope there will be no more evil ghosts in this world."

They rested for a while and then left the valley.

After returning to the town, people heard about their heroic deeds and were filled with gratitude and admiration for them.

Lu Fei and Naruto became heroes of this world and their names will be remembered forever.

However, they know that their mission is not yet completely over. In the days to come, they still need to continue to protect the world and prevent the evil spirits from appearing again.

After a while, Lu Fei and Naruto received a mysterious letter, which mentioned that in a distant place, there was a secret about evil spirits waiting for them to uncover.

"Naruto, do you think this letter is credible?" Lu Fei asked.

Naruto frowned, "I don't know, but I think we should go check it out."

So they set out on their journey again.

They came to the place mentioned in the letter, which was an ancient relic.

The ruins are filled with a mysterious atmosphere that makes people feel creepy.

"Be careful, Lu Fei," Naruto said.

Lu Fei nodded, "Well, I wonder what's in it."

They walked into the ruins and suddenly heard a low roar.

"What's that sound?" Lu Fei looked around vigilantly.

Just then, a huge evil ghost rushed out from the shadows.

This evil ghost was different from any they had encountered before. It exuded an ancient and powerful aura.

"It looks like this is the secret we're looking for," Naruto said.

Lu Fei and Naruto did not retreat and started a fierce battle with the evil spirit.

The evil ghost's attack was so fierce that Lu Fei and Naruto could not resist for a while.

"We can't be defeated like this!" Lu Fei shouted.

Naruto activated the power of the Nine-Tails in his body, "I won't let you succeed!"

Their strength continued to increase, and they gradually became inseparable from the evil spirits.

During the battle, Lu Fei discovered that the evil ghost had a weak spot on his back.

"Naruto, attack its back!" Lu Fei said.

Naruto heard this and quickly rushed to the back of the demon.

The demon sensed their intentions and tried to stop Naruto.

Lu Fei used the power of the Ten-Tails to restrain the evil spirit, creating an opportunity for Naruto.

Naruto successfully hit the Akuma's weak spot and he fell to the ground.

However, just when they thought the battle was over, the evil ghost's body suddenly changed.

Its body began to split and turned into countless little evil spirits.

"What's going on?" Naruto asked in surprise.

Lu Fei said: "It seems that this is the real challenge."

They had to face these large numbers of little evil spirits and launched a tough battle.
