Naruto Bond

The mysterious man attacked without saying anything. Lu Fei and Naruto reacted quickly and fought fiercely with them.

The moves of these mysterious people were strange and their coordination was so tacit that Lu Fei and Naruto were overwhelmed for a while.

"Naruto, be careful!" Lu Fei warned loudly, and at the same time used the power of the Ten Tails to repel several mysterious people who were approaching.

Naruto was not to be outdone, and fully activated the Nine-Tails mode, sending out a powerful chakra storm.

After a hard fight, Lu Fei and Naruto finally gained the upper hand.

"Tell me, who are you? Why do you want to steal the secret book?" Naruto asked, panting.

The leader of the mysterious men sneered: "Humph, this secret book should not have fallen into your hands. Hand it over and I will spare your life!"

Lu Fei shouted angrily: "Don't even think about it! This is what we have gone through so much hardship to get."

The mysterious leader waved his hand: "Continue to attack!"

The battle started again. Although Lu Fei and Naruto were tired, they still fought tenaciously.

At this moment, Naruto suddenly discovered the mysterious man's flaw.

"Lu Fei, cooperate with me!" Naruto shouted.

Lu Fei understood what he meant, and the two of them instantly burst out with powerful strength, repelling the mysterious man in one fell swoop.

The mysterious leader saw that the situation was not good and shouted, "Retreat!"

Looking at the mysterious man walking away, Lu Fei and Naruto breathed a sigh of relief.

"It seems that this secret book is indeed not simple. It has caused so much trouble." Lu Fei said.

Naruto nodded, "Anyway, let's study it and see if there are any clues to get back."

They found a safe place and began to study the secret book carefully.

The text on the secret book is obscure and difficult to understand, filled with various ancient symbols and patterns.

"What should I do? I don't understand it at all." Naruto scratched his head.

Lu Fei pondered for a moment: "Don't worry, we will figure it out slowly."

After several days of hard work, they finally found some clues from the secret book.

"Naruto, look here, it seems to mention a mysterious power, which may be related to our return." Lu Fei said excitedly.

Naruto came closer to take a closer look, "Really? Then let's go find this power."

Following the instructions in the secret book, they came to an ancient cave.

The cave is filled with a mysterious atmosphere, which makes people feel a little uneasy.

"Be careful, Naruto." Lu Fei walked in front carefully.

Suddenly, a low roar was heard from the cave.

"What is that?" Naruto looked around warily.

A huge monster rushed out of the darkness and pounced on them with bared fangs and claws.

Lu Fei and Naruto quickly fought back.

The monster has thick skin and great strength, and Lu Fei and Naruto's attacks seem to have little effect on it.

"This is not a solution. We have to find its weakness." Lu Fei shouted.

Naruto attacked while observing the monster's actions.

Finally, Naruto discovered that the monster's eyes were its weakness.

"Lu Fei, cover me!" Naruto rushed towards the monster.

Lu Fei tried his best to restrain the monster, and Naruto took the opportunity to launch an attack and successfully hit the monster's eye.

The monster roared in pain and fell to the ground.

They continued to go deeper into the cave and finally found the mysterious power mentioned in the secret book.

"That's it!" Lu Fei said excitedly.

However, just as they were preparing to gain this power, a new crisis arose.

The cave began to shake violently, and rocks around it fell off.

"Oh no, this place is going to collapse!" Naruto shouted.

Lu Fei and Naruto ran desperately towards the cave entrance.

At the critical moment, they finally escaped from the cave.

"That was a close call!" Naruto gasped.

Lu Fei looked at the secret book in his hand: "Although it is dangerous, we have found a clue, maybe we are not far from returning."

They continued to search for other clues and methods in the world.

One day, they met a mysterious old man on the road.

The old man looked at the secret book in their hands, and a hint of surprise flashed in his eyes.

"Young man, the secret book in your hands is not something that ordinary people can possess." said the old man.

Lu Fei and Naruto hurriedly asked: "Old man, do you know the secret of this secret book?"

The old man smiled and said, "This secret book is related to an ancient legend. If you can solve the puzzle, perhaps your wish will come true."

Lu Fei and Naruto listened to the old man's story with great anticipation.

After the old man finished speaking, he gave them some hints and left.

Following the old man's instructions, they came to an ancient temple.

The temple is filled with a mysterious atmosphere, as if it hides countless secrets.

"Naruto, be careful." Lu Fei said softly.

They walked into the temple and found many ancient Buddha statues and scriptures inside.

"Do these things have anything to do with our return?" Naruto asked doubtfully.

Lu Fei observed carefully: "Maybe the answer lies in it."

Just as they were studying the Buddha statues and scriptures, a group of dark shadows suddenly appeared in the temple.

"Another enemy!" Naruto was ready to fight.

The shadows quickly attacked them, and Lu Fei and Naruto fought hard.

During the battle, Lu Fei suddenly discovered the black shadow's weakness.

"Naruto, attack their shadows!" Lu Fei shouted.

Naruto followed Lu Fei's instructions and successfully repelled the black shadow.

After some searching, they finally found a hidden chamber deep in the temple.

There is an ancient book in the secret room.

"What is this?" Naruto asked.

Lu Fei opened the scroll, which contained detailed information about secret books and mysterious powers.

"Great, we finally made a new discovery!" Lu Fei said excitedly.

However, just as they were about to leave the secret room, the door of the secret room suddenly closed and a raging fire broke out all around.

"Oh no, we're trapped!" said Naruto.

Lu Fei calmly observed his surroundings: "Don't panic, there must be a way out."

They searched for an exit in the secret room as the fire grew bigger and bigger.

Just when they felt desperate, Naruto discovered a mechanism on the wall.

"Lu Fei, look there!" Naruto shouted.

Lu Fei hurried over and pressed the mechanism.

The door of the secret room slowly opened and they successfully escaped.

"It was really thrilling." Naruto said.

Lu Fei held the scroll and said, "But we have also made some important gains."

Based on the information in the scroll, they continued to look for a way to return.

In a remote valley, they met a hermit master.

After hearing about their experience, the master decided to help them.

"I can help you activate the mysterious power in the secret book, but this requires you to pass a test." said the master.

Lu Fei and Naruto agreed without hesitation.

The test was extremely difficult, but they finally passed it with their firm belief and tenacious perseverance.

The master helped them to activate the mysterious power in the secret book.

Under the influence of mysterious power, a door of time and space slowly opened.

"Is this our way back?" Naruto said excitedly.

Lu Fei nodded: "It should be, let's go."

They walked into the door of time and space, and with a flash of light, they disappeared from this world.
