Naruto Bond

Lu Fei and Naruto continued to explore the dark pyramid with the ancient book. As they walked along the winding passage, they heard a low roar that echoed in the narrow passage, making people shudder.

"Something is waiting for us again." Lu Fei tightly grasped the Thunder Flame Sword, his eyes revealing vigilance and determination.

When they turned a corner, a huge dark demon dog appeared in front of them. The demon dog was as big as a hill, covered with black fur, and its fur was shining with strange runes. Its bloody mouth was full of sharp fangs, and black flames kept spurting out of its mouth. Its four claws left deep marks on the ground, and every step made the ground tremble slightly.

"Awoo!" When the dark demon dog saw Lu Fei and Naruto, it immediately let out a roar, and then pounced towards them like lightning.

Lu Fei was not afraid at all. He rushed towards the dark demon dog, and the flames and lightning power on the Thunder Flame Sword were burning fiercely. "Flame and Thunder Tyrant Slash!" He shouted loudly and launched a powerful slash. A huge flame and thunder sword energy slashed towards the demon dog's head.

The dark demon dog was extremely agile. It turned sideways in the air and easily avoided Lu Fei's attack. Then it turned quickly after landing and pounced on Lu Fei again, grabbing Lu Fei's chest with its sharp claws.

Lu Fei dodged to the side, and the Thunder Flame Sword slashed at the demon dog's leg. The sword blade touched the demon dog's leg, splashing sparks, but only left a shallow scar on the demon dog's leg. The demon dog's defense was far beyond imagination.

Naruto saw Lu Fei getting into a tough fight and immediately used the Shadow Clone Technique. Many Shadow Clone Techniques rushed towards the Dark Demon Dog like a tide, some Shadow Clone Techniques hugged the Dark Demon Dog's body, and some attacked its eyes, trying to distract its attention. The real Naruto quickly formed hand seals on the side, preparing to perform a powerful ninjutsu.

"Senjutsu? Wind Style? Nine-tailed Rasenshuriken!" Naruto shouted, and a huge Rasenshuriken appeared in his hand. He threw the Rasenshuriken towards the Dark Demon Dog. The Rasenshuriken grew bigger as it flew, and nine tails formed by chakra surrounded it, like nine agile dragons, flying towards the Demon Dog with great power.

The Dark Demon Dog sensed the threat from behind, and it shook its body vigorously, throwing away all the shadow clones that were hugging it, and then turned around and sprayed a stream of black flames towards the spiral shuriken. The flames collided with the spiral shuriken, causing a violent explosion, and the powerful impact blew away all the shadow clones around it.

During the battle, Lu Fei discovered that when the dark demon dog launched a fire attack, its abdomen would be briefly exposed, and the defense there seemed to be relatively weak.

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

After hearing this, Naruto immediately ordered his shadow clones to change their attack strategy and attack the belly of the dark demon dog with all their strength. The real Naruto then used "Senjutsu? Lava Release? Rasenshuriken" and threw it towards the belly of the demon dog.

The Lava Rasenshuriken carried high-temperature lava and accurately hit the dark demon dog's abdomen. The demon dog let out a painful roar, and the fur on its abdomen was burnt, leaving a wound, and black blood flowed out of the wound.

Lu Fei took the opportunity to perform the "Flame Thunder Final Slash". He increased the power of the Thunder Flame Sword to the extreme and slashed at the wound on the dark demon dog's abdomen with all his strength. This sword contained a powerful force and successfully pierced the demon dog's abdomen. The demon dog's huge body fell down with a bang, raising a cloud of dust.

However, before they could catch their breath, a large amount of dark slime suddenly gushed out from the surrounding walls. This slime rushed towards them like a tide, corroding the ground into large pits wherever it went.

"What the hell is this?" Naruto said with a frown.

Lu Fei quickly thought of a countermeasure. He found that the slime seemed to be flowing out from some small holes in the wall. "Naruto, attack those small holes and stop the slime from flowing out!"

Naruto nodded, and he used the Shadow Clone Technique, and the shadow clones attacked the small hole in the wall. Some of the shadow clones attacked with fists and feet, while others used ninjutsu to try to block the small hole.

Lu Fei used the Thunder Flame Sword to clear a path in front of him, evaporating the approaching mucus. However, the mucus continued to pour out, and their situation was still very dangerous.

During the battle, Lu Fei discovered that the mucus would form some whirlpools during the flow. The center of the whirlpool seemed to be the energy gathering point of the mucus. If the center of these whirlpools could be destroyed, perhaps the flow of the mucus could be stopped.

"Naruto, attack the center of the slime vortex!" Lu Fei shouted.

After hearing this, Naruto immediately ordered his shadow clones to attack the center of the slime vortex. The real Naruto used the "Senjutsu Super Large Rasengan" and threw it towards the center of a larger slime vortex.

The Rasengan accurately hit the center of the slime vortex, and the vortex dissipated instantly, and the surrounding slime stopped flowing. Lu Fei took the opportunity to increase the power of the Thunder Flame Sword to the maximum, and slashed at the center of the other slime vortices one by one.

After a hard fight, they finally succeeded in stopping the attack of the dark slime.

"The dangers in this pyramid are one after another." Naruto wiped the sweat from his forehead.

"Well, we have to find the exit as soon as possible and leave this damn place." Lu Fei said.

They continued to search for an exit inside the pyramid, and at the top of a hall, they found a huge dark portal. The portal exuded a strong dark aura and was surrounded by some mysterious runes.

"This portal looks suspicious. I don't know where it leads to." Lu Fei said while looking at the portal.

"No matter where it leads, we have to check it out. Maybe we can find a clue to leave the pyramid." Naruto said.

They approached the portal carefully, and when they got close, the portal suddenly generated a strong suction force, sucking them into the portal. Lu Fei and Naruto were sucked into the portal before they could resist.

After a dizzy spell, they found themselves in an unfamiliar space filled with thick dark fog, with strange lights flashing from time to time.

"What is this place?" Lu Fei looked around vigilantly.

At this moment, a voice sounded in their ears: "Welcome to the dark abyss, you will stay here forever!"
