Naruto Bond

Following the clues in the books, Lu Fei and Naruto first headed towards the volcanic area where the fire element gems were said to be hidden. Along the way, the closer they got to the volcanic area, the higher the temperature became, the hotter and drier the air became, the surrounding land turned charred, and some strange plants that could withstand high temperatures grew sporadically.

When they arrived at the foot of the volcano, they saw thick smoke constantly billowing out of the crater in front of them. From time to time, magma flowed out from the cracks in the mountain, winding down the mountain. Wherever it went, it was red and exuded a suffocating high temperature atmosphere.

"This place looks dangerous, but the gem should be nearby. Let's look for it carefully." Lu Fei said, holding the Thunder Flame Sword tightly and observing his surroundings vigilantly.

Naruto nodded and activated Sage Mode to better deal with any situation that might arise at any time. They slowly climbed up the mountainside of the volcano. The hot rocks burned their feet, but both of them gritted their teeth and persisted.

At this moment, several strange birds with flames all over their bodies suddenly flew out from the crater. These strange birds were huge, with wingspans several meters wide. Their feathers were like burning flames, their eyes were fierce, and their sharp beaks and claws looked particularly sharp under the light of the fire. They swooped down towards Lu Fei and Naruto.

"Be careful!" Lu Fei shouted, wielding the Thunder Flame Sword and performing the "Flame Thunder Flash Slash", and sword energy with the power of fire and lightning slashed at the strange birds. The sword energy hit the strange birds, and although the flames on their bodies shook a few times, these strange birds seemed not to be afraid of the pain, and still screamed and pounced.

Seeing this, Naruto used the Shadow Clone Technique. Many of the shadow clones dispersed, some to attract the attention of the strange birds, while others found the right time to attack the eyes, wings and other vital parts of the strange birds. The real Naruto quickly formed a seal on the side, "Senjutsu? Wind Style? Nine-tailed Rasenshuriken!" With a loud shout, the huge Rasenshuriken flew towards the densest part of the strange birds. The Rasenshuriken continued to grow larger during the flight, and the powerful force swept several strange birds into it. With a violent explosion, the feathers of the strange birds were blown up and they fell down screaming.

However, more strange birds flew out from the crater continuously. They seemed to feel threatened and attacked more and more frantically. They began to form formations in the air and charged alternately, making Lu Fei and Naruto overwhelmed.

During the battle, Lu Fei discovered that every time these strange birds launched a dive attack, when they folded their wings and prepared to fly again, their abdomens would be briefly exposed, and the fire protection there was relatively weak.

"Naruto, attack their abdomen, that's their weak point!" Lu Fei shouted loudly.

After hearing this, Naruto immediately ordered his shadow clones to change the direction of attack and attack the belly of the strange birds. The real Naruto used "Senjutsu? Lava Release? Rasenshuriken", and the high-temperature Lava Release Rasenshuriken with blazing flames accurately hit the belly of a strange bird. The flames in the belly of the strange bird were extinguished a lot in an instant, and the body also swayed and fell down, and it was obviously seriously injured.

Lu Fei took the opportunity to use the "Flame Thunder Demon-Breaking Slash", increasing the power of the Thunder Flame Sword to the extreme, and slashed at the abdomen of the other monster birds with all his strength. One by one, the monster birds were injured and fell under their attack, and the originally dense attack formation was also disrupted.

After a hard fight, they finally repelled all the fire birds. Continuing to search on the volcano's mountainside, they soon came to a hidden cave. The rocks around the cave were a special red color, faintly emitting a fiery breath, which was consistent with the characteristics of the place where the fire element gem was described in the classics.

"Maybe the gem is in this cave." Naruto said.

They walked into the cave carefully. The temperature inside the cave was even higher. Magma flowed on the walls, and from time to time, magma dripped onto the ground, splashing small sparks. Going deeper along the winding passage of the cave, at the end, they saw a stone platform emitting a strong red light. On the stone platform was a gem that burned like a flame. It was the fire element gem.

"Found it!" Lu Fei said excitedly, and stepped forward to pick up the gem. But just as his hand was about to touch the gem, a circle of flames suddenly emerged around the stone platform, and the flames burned fiercely. The scorching heat forced Lu Fei to quickly retract his hand.

"This barrier looks difficult to deal with. We have to find a way to break it." Lu Fei said with a frown.

They began to observe the flame barrier carefully and found that the flames on the barrier were not burning randomly, but flowing according to a certain pattern, as if forming some kind of ancient formation. After some research, they found that as long as they followed the reverse order of the flame flow and injected the corresponding power at the same time, they might be able to break the barrier.

Lu Fei and Naruto looked at each other in tacit understanding, and then acted at the same time. Lu Fei injected the power of the Thunder Sword into the flame barrier at a specific rhythm, and Naruto concentrated his chakra and guided the power input in the same way. As they operated, the flames on the flame barrier began to become disordered, and the light gradually dimmed. Finally, the barrier disappeared.

Lu Fei successfully picked up the fire element gem. The gem felt warm to the touch, as if an endless power was surging within it.

"With this gem, we are one step closer to success. Next, we should look for gems of other elements." Lu Fei said.

"Well, let's get going quickly. I hope we can find it smoothly later." Naruto responded.

They left the volcanic area with the fire element gem, and based on the clues, headed towards the mysterious forest where the wood element gem might be hidden.
