Naruto Bond

After successfully defeating the mysterious figure and eliminating the threat of the magic circle, Lu Fei and Naruto took a short break before setting off again. They walked along a rugged mountain road, and the scenery along the road kept changing, sometimes with steep peaks and sometimes deep canyons.

"Lu Fei, we have resolved another crisis this time, but it feels like the dangers in this world are always endless." Naruto looked into the distance, his eyes filled with both worry and determination.

Lu Fei nodded slightly, holding the Thunder Flame Sword tightly, "That's right, we can't let our guard down. There are still many unknown dangers in this world waiting for us to face."

As they were walking, they suddenly heard a melodious music coming from afar. The music sounded ethereal and beautiful, as if it came from another world.

"What's that sound?" Naruto looked around curiously.

Lu Fei also became alert, "Be careful, this music may be unusual. Let's go and take a look."

They followed the direction of the music and soon came to a beautiful valley. The valley was full of bright flowers and a clear stream was flowing. In the center of the valley, a mysterious woman was playing a strange instrument.

The woman was wearing a white robe, with long flowing hair, and her eyes were full of tenderness and mystery. She saw Lu Fei and Naruto and smiled slightly.

"Who are you? Why are you here?" The woman's voice was as sweet as music.

Lu Fei stepped forward and said respectfully, "We are warriors who set out on a journey to protect this world. We were attracted here by your music. May I ask who you are? Where is this place?"

The woman gently put down the instrument in her hand. "I am the guardian of this valley. This is a place full of peace and tranquility, but recently I feel that an evil force is approaching, which may bring disaster to this world."

Lu Fei and Naruto looked at each other, and a sense of responsibility surged in their hearts. "We will help you protect this valley and prevent the invasion of evil forces."

The woman nodded. "Thank you. But this evil force is very strong. You must be careful."

They began to look for traces of evil forces in the valley. After some exploration, they found a dark cave deep in the valley, which exuded an evil breath.

"This cave is likely the source of evil power." Lu Fei said.

Naruto nodded, "Let's go in and take a look."

They walked into the cave carefully. It was dark and damp, with strange lights flickering on the walls. Deep in the cave, they found a huge magic circle.

"This is very similar to the magic circle we encountered before." Naruto said.

Lu Fei observed the magic circle carefully, "Yes, but this magic circle is more complicated and powerful. We must deal with it carefully."

Just as they were thinking about how to crack the magic circle, it suddenly activated, and a powerful dark force surged out of it. A huge demon figure emerged from the darkness.

"How dare you trespass into my territory? You really don't know how to live or die." The devil's voice was low and terrifying.

Lu Fei and Naruto looked at the demon without fear, "We won't let you destroy this world."

They used their respective powers to start a fierce battle with the demon. The demon's attack was powerful and strange, causing Lu Fei and Naruto to fall into a tough battle. But they did not retreat at all, relying on their tenacious will and tacit cooperation, they gradually stabilized their position.

During the battle, Lu Fei discovered that although the demon's attack was powerful, it seemed to have a weakness. Every time the demon launched a powerful attack, there would be a brief pause.

"Naruto, pay attention to his weakness and take the opportunity to attack." Lu Fei shouted.

Naruto immediately understood what Lu Fei meant. They waited for the opportunity, and when the demon launched another powerful attack, they launched a counterattack at the same time.

Lu Fei wielded the Thunder Flame Sword, and the flames on the sword intertwined with the lightning to form a huge beam of light, slashing towards the demon's weakness. Naruto also used the immortal method? The Super Jade Rasengan, which flashed with golden light and contained great power.

The demon was hit by this sudden attack and roared in pain. His body was knocked back by the powerful force and fell heavily to the ground.

But the devil was not so easily defeated. He stood up quickly, and the aura on his body became even more evil.

"Do you think you can defeat me like this? You are too naive." The devil roared.

He began to absorb the power of the magic circle frantically. His body became larger and larger, and his aura became stronger and stronger.

Lu Fei and Naruto looked at the changes of the demon and were shocked. They knew that the demon had gone crazy and if they didn't stop him as soon as possible, the consequences would be disastrous.

"Naruto, we can't let him continue to absorb the power of the magic circle." Lu Fei shouted.

Naruto nodded, and they once again exerted their strongest power and rushed towards the demon. But at this time, the demon had become extremely powerful, and their attacks seemed to have little effect on him.

At this critical moment, Lu Fei suddenly thought of the woman's music, and decided to try to use the power of music to fight the devil.

"Naruto, let's recall the girl's music together, maybe it can help us." Lu Fei said.

Naruto hesitated for a moment, then nodded. They closed their eyes and recalled the woman's music. Gradually, their hearts were filled with peace and strength.

They rushed towards the demon again, and this time, their attack was carried by the power of music and was extremely powerful.

The demon felt this powerful force and showed a look of fear on his face. But he was too late to dodge and was hit by Lu Fei and Naruto's attacks.

After a loud bang, the demon was blown to pieces. The magic circle also lost its power and gradually disappeared.

Lu Fei and Naruto breathed a sigh of relief. They knew that although this battle was difficult, they had successfully protected the world again.

They walked out of the cave and found the woman. Seeing that they had successfully defeated the demon, the woman smiled with relief.

“Thank you, brave warriors. You have protected this valley and this world,” said the woman.

Lu Fei and Naruto smiled modestly, "This is what we should do. We will continue to move forward and fight to protect this world."

They said goodbye to the woman and continued on their journey.
