Naruto Bond

Lu Fei and Naruto took the clues given by the mysterious man and continued to move deeper into the cave. At this time, the atmosphere in the cave became more and more solemn, and every step seemed to be stepping on unknown dangers.

They walked along the winding passage, the light on the wall flickering, as if foreshadowing the coming storm. Lu Fei tightly grasped the Thunder Flame Sword, the blade trembling slightly, as if eager to fight. Naruto mobilized the chakra in his body, and the power of the golden nine-tails formed a protective barrier around his body.

"I wonder what's waiting for us ahead." Naruto whispered.

Lu Fei frowned slightly, his eyes revealing determination, "No matter what it is, we must face it bravely."

Suddenly, a low roar came from the front. The ground began to tremble slightly, as if a powerful force was approaching.

"Be careful! Something's happening!" Lu Fei shouted.

Naruto immediately prepared for battle, and the golden nine-tailed beast's chakra surged more violently. "Come on, let's see what kind of monster it is."

As the roar got closer, a huge figure rushed out from the darkness. It was a monster covered with hard scales, its body was as big as a hill, and its eyes flashed red fierce light. The monster opened its bloody mouth, revealing sharp teeth, and a black smoke blew out of its mouth.

"What the hell is this guy?" Naruto asked in surprise.

Lu Fei held the Thunder Flame Sword tightly, "It looks like a powerful magical creature. We must be careful when dealing with it."

The monster saw Lu Fei and Naruto and immediately launched an attack. It swung its huge claws and slapped them. The claws were so powerful that the air was compressed and made a hissing sound wherever it passed.

Lu Fei immediately unleashed the power of the Thunder Flame Sword, and the flames and lightning on the sword intertwined into a powerful barrier, blocking the monster's attack. The lightning and flames flashed in the air, colliding with the monster's claws, making loud noises.

Naruto was not to be outdone, he used the power of the golden nine-tailed beast, and a huge beast jade condensed in his hand. He threw the beast jade towards the monster, and the beast jade exploded, and the powerful impact made the monster retreat a few steps.

The monster was enraged, and it attacked again. This time, it opened its mouth and spit out a black flame. This flame carried a powerful magical force and swept towards Lu Fei and Naruto.

Lu Fei and Naruto quickly dodged the black flames. They quickly shuttled through the cave, using the terrain and rocks to avoid the monster's attacks.

During the battle, Lu Fei and Naruto kept looking for the monster's weakness. They found that the monster's abdomen was relatively soft, which might be its weakness.

"Naruto, attack its belly." Lu Fei shouted.

Naruto nodded, and he used the power of the golden nine-tailed beast, and a huge tailed beast jade flew towards the monster's abdomen. The tailed beast jade exploded, and the powerful impact caused severe damage to the monster's abdomen.

The monster roared in pain, and its body began to shake. Lu Fei took the opportunity to strike with all his strength, and the Thunder Flame Sword slashed the monster's body, cutting a deep crack in its scales.

However, the monster was not so easily defeated. It began to fight back frantically, waving its claws and tail continuously, and its attack speed became faster and faster.

Lu Fei and Naruto were in a tough fight. They kept dodging the monster's attacks while looking for opportunities to counterattack. Lu Fei used the flexibility of the Thunder Flame Sword to quickly slash at the monster's claws and tail, trying to weaken its attack power.

Naruto used various ninjutsu, alternating between wind ninjutsu, fire ninjutsu and other ninjutsu, trying to cause greater damage to the monster.

At the critical moment, Lu Fei thought of a way. He decided to use the special power of the Thunder Flame Sword to try to absorb the monster's magical power, and then use this power to attack the monster.

"Naruto, help me attract the monster's attention so I can absorb its power." Lu Fei shouted.

Naruto agreed without hesitation. He used the strongest power of the Golden Nine-Tails, threw a huge Tailed Beast Ball at the monster, and continuously used ninjutsu to attack the monster, attracting its attention.

Lu Fei took the opportunity to insert the Thunder Flame Sword into the ground, and the light on the sword began to flicker. He concentrated his energy and tried to absorb the monster's magical power.

At first, the magic power was very resistant, but as Lu Fei continued to work hard, some of the magic power began to be absorbed by the Thunder Flame Sword. The light on the sword became more dazzling, and it was also filled with the magic breath of the monster.

After absorbing enough magic power, Lu Fei launched a full-strength attack. He swung the Thunder Flame Sword, and a powerful sword energy flew towards the monster. This sword energy combined the magic power of the monster and the power of the Thunder Flame Sword, and was extremely powerful.

The sword energy hit the monster's head accurately, and the monster roared in pain. Its body began to collapse and finally fell to the ground.

As the monster fell, peace returned to the cave.
