Naruto Bond

Lu Fei's heart moved, he tightly grasped the Thunder Flame Sword, feeling the powerful force on the sword. This force seemed to resonate with his heart, giving him endless courage and confidence.

"Naruto, I feel the power of the Thunder Flame Sword is increasing. We still have a chance!" Lu Fei said loudly.

Naruto looked at Lu Fei, and the flame of hope rekindled in his eyes. "Okay, let's fight to the end together!"

The more mysterious figure looked at Lu Fei and Naruto, with the corners of his mouth slightly raised, revealing a contemptuous smile. "Do you think you can defeat me like this? Too naive."

He raised the golden sword again, and the sacred aura on the sword became even stronger. An even stronger golden sword energy attacked Lu Fei and Naruto, so fast that it was impossible to dodge.

Lu Fei and Naruto stared at the golden sword energy, they knew that this was a life-and-death battle. At this critical moment, Lu Fei suddenly thought of a risky way.

"Naruto, inject your chakra into my Thunder and Flame Sword!" Lu Fei shouted.

Naruto did not hesitate at all and immediately injected the Golden Nine-Tails' chakra into the Thunder and Flame Sword. With the injection of chakra, the flames and lightning of the Thunder and Flame Sword became more violent, and the sword body began to tremble slightly.

Lu Fei felt the powerful force of the Thunder Flame Sword, and he shouted loudly, swinging the Thunder Flame Sword towards the golden sword energy. The flames and lightning on the sword intertwined into a huge beam of light, which collided fiercely with the golden sword energy.

A deafening roar sounded, and the powerful impact force made the surrounding space seem to be distorted. Lu Fei and Naruto were knocked back by the impact force, but their eyes were always fixed on the center of the collision.

The light column of the Thunder Flame Sword and the golden sword energy were in a stalemate, and the forces of both sides were constantly confronting each other. The more mysterious figure showed a hint of surprise on his face. He did not expect Lu Fei and Naruto to be able to withstand his attack.

"Hmph, it's nothing more than a dying struggle." The even more mysterious figure snorted coldly and increased his power output again.

The golden sword energy became even bigger and began to slowly press towards the light column of the Thunder Flame Sword. Lu Fei and Naruto felt a huge pressure, and their bodies seemed to be crushed by this force.

But they did not give up, still gritting their teeth and persisting. Lu Fei continued to mobilize the power of the Thunder Flame Sword, trying to resist the oppression of the golden sword energy. Naruto also continued to inject chakra to maintain the power of the Thunder Flame Sword.

Just when they were about to give up, a stronger force suddenly erupted from the Thunder Flame Sword. This force instantly repelled the golden sword energy and rushed towards the more mysterious figure.

The more mysterious figure was horrified, and he hastily swung his golden sword to try to resist the force. But the force was too strong, and his golden sword was blown away the moment it came into contact with the force.

The more mysterious figure was hit by this force, and his body flew backwards and fell heavily to the ground. He spat out a mouthful of blood, with an expression of disbelief on his face.

Lu Fei and Naruto were filled with joy when they saw the more mysterious figure being defeated, but they knew that the battle was not over yet.

They immediately rushed towards the more mysterious figure, ready to launch the final attack. The more mysterious figure looked at Lu Fei and Naruto rushing over, with a look of despair on his face.

Just as Lu Fei and Naruto were about to attack the more mysterious figure, suddenly, there was a strong vibration in the sky. A dazzling light shot down from the sky, covering Lu Fei and Naruto.

Lu Fei and Naruto looked up in surprise, only to see a huge figure slowly emerging from the light. This figure exuded an extremely powerful aura, which made people feel awe.

"I am amazed by your courage and strength." said the huge figure, his voice like a bell, echoing in the air.

Lu Fei and Naruto looked at this huge figure, their hearts full of doubts. They didn't know who this figure was, nor did they know why he appeared here.

"I am the guardian of this world, and I feel your determination and courage. In order to protect this world, you are willing to fight against powerful enemies. I admire your actions." said the guardian.

Lu Fei and Naruto felt a surge of pride after hearing the words of the guardian. They knew that their efforts were not in vain.

"Now, I will give you more powerful power so that you can continue to protect this world." After the guardian finished speaking, a ray of light shot out from his hand and enveloped Lu Fei and Naruto.

Lu Fei and Naruto felt a powerful force surging into their bodies, and their strength was greatly enhanced in an instant.

"Thank you, Guardian!" Lu Fei and Naruto said gratefully.

The guardian nodded slightly, then disappeared into the light.

Lu Fei and Naruto looked at each other, knowing that although this battle was difficult, they had gained stronger power. They would continue to move forward, and they would never give up in order to protect the world and find the Dragon Balls.

They turned around and prepared to leave the battlefield, but at this moment, they suddenly felt a familiar breath coming from a distance.

Lu Fei and Naruto looked at each other, feeling uneasy. They knew that this aura meant that a new enemy had appeared.

Sure enough, after a while, a figure slowly approached from a distance. This figure exuded an evil aura that made people shudder.

"Do you think this is the end? You are too naive." The figure said with a sneer.

Lu Fei and Naruto held their weapons tightly, ready to face new challenges.
