Naruto Bond

Faced with this group of ghostly figures, Lu Fei and others immediately entered combat status.

Lu Fei waved his hands, and the power of thunder and lightning gathered in his palms. "Ten-tailed? Thunder Release? Thunder Punishment Heavenly Might Net!" A huge thunder and lightning net instantly unfolded, trying to trap these ghosts. Electric current shuttled through the net, making a "crackling" sound.

Naruto quickly formed seals with both hands, "Senjutsu? Wind Style? Vacuum Wave Continuous Shooting!" Powerful wind blades shot out from his hands and cut into the group of ghosts. Wherever the wind blades passed, the fog was stirred up and became thicker, and the figures of the ghosts were erratic in the wind.

Huaye Hongxu shouted, and the spirit sword shone brightly, "Spirit sword? Spiritual light purification!" The light released by the spirit sword was like a scorching sun, illuminating the entire room. Under the light, the ghosts screamed in pain, and their figures became illusory.

Flame Hall's Lu Lu was not to be outdone. He swung his flaming sword, "Sword of Flame? Flame Burns the Sky!" Flames gushed out from the sword, forming a huge vortex of flames that drew approaching ghosts into it and burned them to death.

At this moment, lightning, wind blades, light, and flames intertwined in the room. The mist was surging under the impact of various forces, and those strange instruments and statues were also trembling in the collision of light and power, as if they would collapse at any time.

The ghosts kept shuttling between various attacks, trying to get close to everyone. Their figures appeared and disappeared, and every time they appeared, they brought a cold breath that made people's backs chill.

Although Lu Fei's lightning net is powerful, the ghosts can always find gaps to pass through.

Although the wind blades shot by Naruto were sharp, the ghosts were extremely fast and were able to dodge them quickly.

Although the light of Huaye Hongxu's spiritual sword can temporarily suppress ghosts, the range of the light is limited.

Although the flame vortex of the Flame Demon Hall's windlass is extremely powerful, it also consumes a lot of energy.

As the battle continued, everyone's physical strength and power were gradually consumed.

Lu Fei's forehead was covered with sweat. He gritted his teeth and increased the output of lightning, "Ten Tails? Lightning Release? Thunder Punishment Heavenly Power Explosion!" The power of lightning exploded instantly, forming a dazzling light in the room. Several ghosts dissipated under this powerful attack.

Naruto also performed a more powerful wind jutsu, "Senjutsu? Wind jutsu? Continuous shooting of super-large jade spiral shurikens!" Several huge wind jutsu spiral shurikens flew out, whistling in the room, and crushed a group of ghosts.

Huaye Hongxu concentrated his mind and exerted the power of the spirit sword to the extreme, "Spirit sword? Spiritual light judgment!" The spirit sword released a powerful sword energy of light, which pierced through the bodies of several ghosts.

Flame Demon Hall's Lu Lu gasped heavily, "Sword of Flame? Yanyan Burns the Sky and Destroys!" The flame on the flaming sword turned into a huge fire dragon, rushing towards the group of ghosts, burning a large number of ghosts into ashes.

The battle in the room became more intense, bricks and stones on the wall began to fall, and cracks appeared on the ground. Those strange instruments were destroyed in the battle, and parts flew everywhere.

The ghosts' attacks became more and more frantic. They let out shrill screams, forming an invisible pressure that made everyone feel difficult to breathe.

Lu Fei and others gritted their teeth and fought desperately.

Finally, with everyone's unremitting efforts, the ghosts gradually decreased and eventually disappeared completely.

The room returned to calm, leaving only a mess.

The fog gradually dissipated, and everyone could see the whole room. The walls were covered with ancient runes and patterns, the ground was crisscrossed with cracks, and the remains of instruments were scattered all over the ground.

"Where the hell is this place?" Hua Ye Hong Xu looked around and said puzzledly.

"I don't know, but we have to keep moving forward and find the answer," Lu Fei said.

They rested for a while and continued to walk deeper into the castle.

Next, they came to a huge library with towering bookshelves filled with thick books.

However, before they could get a closer look, the bookshelves began to move, and a giant book monster slowly emerged from behind them.

The body of the book monster is made up of countless books, each of which is like a scale of its own, sparkling with mysterious light.

"Be careful!" shouted Flame Hall Lu Lu.

The book monster opened its mouth and spewed out a powerful torrent of knowledge, rushing towards everyone.

Lu Fei reacted quickly, "Ten Tails? Lightning Release? Thunder Punishment Heavenly Shield!" The shield formed by lightning blocked everyone in front of him and resisted the impact of the torrent of knowledge.

Naruto formed seals with his hands, "Senjutsu? Wind Style? Wind Binding!" A gust of wind wrapped around the book monster's body, trying to restrict its movements.

Huaye Hongxu waved the magic sword, "Spirit sword? Spiritual light piercing!" The light of the magic sword shot towards the book monster's eyes.

Flame Demon Hall's Lu Lu took the opportunity to rush forward, "Sword of Flame? Yanyan Burning Sky Slash!" The flaming sword slashed towards the book monster's body.

The book monster roared, and the books on its body kept flipping, releasing various magical powers.

For a moment, the library was filled with light, and the power of magic collided with the attacks of the crowd.

The bookshelves collapsed during the battle, books fell one after another, and the ground was covered with books.

After a fierce battle, everyone finally found the book monster's weakness and defeated it.

They continued to explore the castle, and every corner was full of unknowns and dangers.

In a mysterious laboratory, they encountered a monster made of potions and machines.

The monster's body continuously spewed out poisonous liquid, and the air was filled with a pungent smell.

Lu Fei and others joined the battle again...
