Naruto Bond

Lu Fei and Naruto ran quickly towards the village, and all they saw along the way was the tragic scene of destruction, which strengthened their determination to stop the evil forces.

As soon as they entered the village, they heard a fierce fight. They looked in the direction of the sound and saw a group of dark magicians in black robes fighting with a group of villagers' self-defense forces in the square in the center of the village. The dark magicians kept releasing black magic flames and evil curses. Although the villagers fought hard, they suffered heavy casualties due to the disparity in strength.

Lu Fei rushed into the battle circle without hesitation, and as he swung the Thunder Sword, the power of fire and lightning surged out, dispelling the dark magic that approached the villagers one by one. He cast the "Flame and Thunder Guardian Array" to form a shining energy shield around the villagers, temporarily resisting the attack of the dark magician.

Naruto also quickly joined the battle. He quickly formed seals with both hands, "Senjutsu? Wind Style? Rasenshuriken!" The huge Rasenshuriken, with powerful chakra fluctuations, flew towards the place where the dark magicians were most concentrated. Wherever the Rasenshuriken went, the dark magicians were knocked away one after another, their black robes were torn, and black blood spit out of their mouths.

However, the dark magicians did not retreat. They quickly adjusted their formation, chanted something, and began to cast a more powerful dark fusion magic. Huge black energy balls gathered at the tops of their staffs, and these energy balls merged with each other, gradually forming a huge dark vortex, which exuded a chilling suction and destructive aura.

"Be careful, this magic is quite powerful!" Lu Fei warned loudly. He injected the power of the artifact into the Sword of Thunder and Flame, preparing for the upcoming powerful impact.

Naruto summoned many shadow clones, which ran around the dark vortex quickly, trying to disrupt the dark magicians' spells. The real Naruto gathered the fairy chakra on the side, ready to launch a fatal attack.

After the dark vortex took shape, it suddenly shot towards the direction where Lu Fei and the villagers were. Lu Fei jumped high, and the flame and lightning power on the Thunder Flame Sword reached its peak, "Flame Thunder Breaks Evil Slash!" He slashed a huge sword energy towards the dark vortex, and the sword energy collided with the dark vortex, making a thunderous roar. For a moment, light and darkness intertwined, and powerful energy fluctuations spread all around, overturning the surrounding houses and tearing the ground into deep gullies.

When Lu Fei and the dark vortex were in a stalemate, Naruto seized the opportunity and used "Senjutsu? Lava Release? True Flame Rasenshuriken!" He threw this ninjutsu that combined Lava Release, Senjutsu and his own powerful chakra at the dark magicians. The Rasenshuriken was like a burning sun, carrying a high temperature and powerful force that could destroy the world, flying towards the dark magicians.

The dark magicians were busy maintaining the dark vortex and had no time to pay attention to the spiral shuriken thrown by Naruto. The spiral shuriken hit them accurately, causing a huge explosion in an instant. The high temperature and impact force generated by the explosion swallowed up all the dark magicians. They screamed in pain in the flames and their bodies were burned to ashes.

With the destruction of the dark magicians, the village temporarily returned to peace. Lu Fei and Naruto began to help the villagers treat the wounded and repair their houses. The villagers were grateful to them and took out the best food and items in their homes to entertain them.

"Thank you. If it weren't for you, our village would be finished," said the village chief with tears in his eyes.

Lu Fei smiled and said: "This is what we should do. Protecting this continent is our mission."

Naruto, on the other hand, wolfed down his food and mumbled, "Well, as long as everyone is safe."

After a night's rest in the village, Lu Fei and Naruto continued their journey. They followed the traces of the dark power and came to a barren desert. The wind was howling in the desert, the sky was full of yellow sand, and the scorching sun made the earth hot.

In the center of the desert, they found a huge dark castle. The castle exuded a strong dark atmosphere, and the walls were full of various evil creatures and dark soldiers. The castle gate was closed, and it was surrounded by powerful magic traps and defense facilities.

"It seems that this is the lair of evil forces. We must be careful." Lu Fei looked at the dark castle and said solemnly.

Naruto nodded, "Yes, we must completely destroy them this time."

They approached the dark castle cautiously, trying to find a way to break through the defense. Suddenly, a huge wave of sand surged in the desert, and a huge sandworm appeared in the sand. The sandworm was huge, covered with hard sand armor, and its mouth was full of sharp teeth. It quickly crawled towards Lu Fei and Naruto.

Lu Fei and Naruto immediately entered combat mode. Lu Fei swung the Thunder Flame Sword and slashed at the sandworm's head. The sandworm sensed the danger and quickly hid its head in the sand, then emerged from Lu Fei's side and opened its bloody mouth to bite him. Lu Fei dodged to the side, and the Thunder Flame Sword slashed at the sandworm's body, leaving a shallow mark on the sand worm's armor.

Naruto performed the Shadow Clone Technique, and many of them rushed towards the sandworm. Some of them hugged the sandworm's body, and some attacked the sandworm's eyes, trying to distract its attention. The real Naruto gathered chakra on the side, preparing to perform a powerful ninjutsu.

The sandworm seemed a little annoyed by the attacks of the shadow clones. It twisted its body hard, threw the shadow clones away, and rushed towards Naruto. Naruto was not in a hurry, and quickly formed seals with both hands, "Senjutsu? Earth escape? Rock pillar prison!" He summoned several huge rock pillars in the sandworm's path, and the rock pillars trapped the sandworm and made it unable to move.

Lu Fei took the opportunity to rush forward. He combined the Thunder Flame Sword with the power of the artifact and performed the "Flame Thunder World-Destroying Slash". This sword contained a powerful force and slashed towards the sandworm's head. The Flame Thunder World-Destroying Slash accurately hit the sandworm's head, and the sandworm's head was cut off. The huge body fell down with a bang, raising a cloud of yellow sand.

After dealing with the sandworms, they continued to move towards the dark castle. When they approached the castle gate, the magic traps around the castle were triggered. Black magic rays shot out from the ground and shot towards them. Lu Fei and Naruto quickly dodged, dodging left and right under the attack of the magic rays, looking for a way to break through the trap.

While dodging, Lu Fei discovered that the emission of these magic lights had a certain pattern, and they seemed to be operating according to some specific formation.

"Naruto, these magic lights have a pattern. We should follow the flaws in the formation!" Lu Fei shouted.

After hearing this, Naruto immediately understood what Lu Fei meant. They began to carefully observe the order in which the magic light was emitted, and then walked carefully towards the castle gate according to the flaws in the formation. With their efforts, they finally successfully passed through the magic trap and arrived in front of the castle gate.

The castle gate was tightly closed, and all kinds of evil runes and patterns were engraved on the gate. Lu Fei and Naruto tried to force the gate open, but the gate was extremely strong and their attacks had no effect on the gate.

"It seems that this door requires a specific method to open. Let's look for clues." Lu Fei said.

They began to look for clues around the castle gate, and after a careful search, they found some strange symbols on a stone tablet next to the gate. These symbols looked somewhat similar to the runes they had seen in the temple before, but not exactly the same.

Lu Fei and Naruto began to study these symbols, trying to find a way to open the door. During the research, they gradually discovered that these symbols were an ancient code that required a specific force and sequence to decipher.

"I think I know how to open the door." Lu Fei said suddenly. He inserted the Thunder Flame Sword into the ground. The power of the artifact was injected into the ground through the Thunder Flame Sword, resonating with the symbols on the stone tablet.

Naruto also injected his chakra into the stone tablet, and according to Lu Fei's instructions, they activated the symbols on the stone tablet in a specific order and strength. As the symbols were activated, the castle gate slowly opened, and a strong dark aura poured out from the castle.

"It's finally opened, let's go in!" Naruto said excitedly.

They stepped into the dark castle.
