Naruto Bond

Lu Fei and Naruto continued to move forward in the forest. The sunlight shone through the gaps between the branches and leaves, forming patches of light. The surroundings were filled with the fresh fragrance of grass and soil.

As they walked, they heard a noisy sound coming from the front. The two approached the source of the sound carefully and found that it was a group of soldiers in black armor besieging a huge unicorn. The unicorn was snow-white, with a spiral horn on its forehead, emitting a soft light. Its eyes were full of fear and anger, and it kept digging the ground with its hooves, trying to resist the soldiers' attack.

"What are these guys doing? Why are they attacking unicorns?" Naruto said angrily.

"Something doesn't look right. We have to go help the unicorn." Lu Fei said, then he gripped the Thunder Flame Sword and rushed towards the soldiers.

Naruto immediately used the Shadow Clone Technique, and many Shadow Clone Techniques joined the battle, fighting against the soldiers together with Lu Fei. These soldiers were very powerful, their armor was extremely hard, and the weapons in their hands were wielded vigorously. For a while, both sides were caught in a fierce battle.

Lu Fei used the "Flame Lightning Slash", and the flames and lightning on the sword turned into sharp sword energy, slashing towards the soldiers. The sword energy hit the soldiers' armor, splashing sparks, but the soldiers only stepped back a few steps and did not suffer much damage.

Seeing this, Naruto used "Senjutsu Wind Style Nine-tailed Rasenshuriken" and a huge Rasenshuriken flew towards the densest part of the soldiers. The Rasenshuriken grew bigger as it flew, and the powerful force engulfed several soldiers. With a violent explosion, the soldiers were blown to pieces, but they quickly regrouped and continued to attack.

During the battle, Lu Fei discovered that after each attack of these soldiers, a brief gap would appear at the joints of their armor, which might be their weakness.

"Naruto, attack the connection between their armor, that's the weak point!" Lu Fei shouted loudly.

After hearing this, Naruto immediately ordered his shadow clones to change the direction of attack and attack the joint of the soldier's armor. The real Naruto used "Senjutsu? Molten Release? Rasenshuriken", and the high-temperature Molten Release Rasenshuriken with blazing flames accurately hit the joint of a soldier's armor. The soldier's armor was instantly melted, and his body was severely injured, and he fell to the ground and could not move.

Lu Fei took the opportunity to perform the "Flame Thunder Demon-Breaking Slash", increasing the power of the Thunder Flame Sword to the extreme, and slashed with all his strength at the connection points of other soldiers' armor. Under their attack, the armor of each soldier was damaged, and they lost their combat effectiveness and fell to the ground groaning.

After dealing with the threat from the soldiers, the unicorn walked up to Lu Fei and Naruto, lowered its head, and gently rubbed them with its nose, as if to express its gratitude to them.

"It's okay, little guy, you can go now." Lu Fei said, gently stroking the unicorn's head.

The unicorn neighed happily, then turned and ran deeper into the forest, soon disappearing from their sight.

"Let's keep going, we don't know how many dangers are hidden in this forest." Naruto said.

They walked in the direction the unicorn left, and soon they came to a clear lake. The lake was like a huge mirror, reflecting the surrounding green mountains and trees, which was beautiful. There were some exotic flowers and plants growing by the lake, exuding a faint fragrance.

However, when they approached the lake, the lake suddenly rippled, and a graceful water elf slowly rose from the lake. The water elf's hair fluttered like blue water plants, and her eyes were like clear lake water, emitting soft light. She was wearing a dress made of condensed water droplets and holding a crystal clear magic wand in her hand.

"Dear guests from afar, you have come to my territory. What can I do for you?" The water elf's voice was clear and pleasant, like the sound of flowing lake water.

Lu Fei stepped forward and said, "We are travelers passing by here. We have no intention of offending you. We are just exploring this forest and looking for some power that can help us protect the continent."

The water elf nodded slightly and said, "I feel your kindness and courage. Perhaps I can help you. Deep at the bottom of the lake, there is a mysterious water heart. It contains a powerful water elemental force that can give you the ability to control water. However, there are many dangerous creatures guarding it at the bottom of the lake. You must be careful."

"Thank you for your help. We will be careful." Lu Fei said gratefully.

So Lu Fei and Naruto took a deep breath and dived into the lake. The water was clear and cold, and they swam towards the bottom of the lake. The bottom of the lake was covered with all kinds of water plants and stones, as well as some glimmering gems that illuminated the surrounding environment.

However, they didn't swim far before they encountered a group of ferocious piranhas. These piranhas were small in size but had extremely sharp teeth. They swam towards Lu Fei and Naruto in groups, opened their bloody mouths, and tried to bite them.

Lu Fei wielded the Thunder Flame Sword and performed the "Flame Thunder Sky Slash". The flames and lightning on the sword formed powerful light curtains in the water, trying to resist the attack of the piranhas. Naruto also performed the Shadow Clone Technique, and many shadow clones fought fiercely with the piranhas.

During the battle, Lu Fei discovered that after each attack of these piranhas, a piece of white belly would briefly be exposed on their abdomen, where the defense was relatively weak.

"Naruto, attack their abdomen, that's their weak point!" Lu Fei conveyed the message to Naruto through telepathy.

After hearing this, Naruto immediately ordered his shadow clones to change the direction of attack and attack the belly of the piranha. The real Naruto used "Senjutsu? Lava Release? Rasenshuriken". The high-temperature Lava Release Rasenshuriken with blazing flames in the water accurately hit the belly of a piranha. The piranha was instantly burned, its body twisted in pain, and sank to the bottom of the lake.

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 piranhas with all his strength. Under their attack, one piranha after another was injured and sank to the bottom of the lake, and the lake was filled with blood.

After solving the threat of piranhas, they continued to swim towards the bottom of the lake. Finally, in a cave at the bottom of the lake, they found the water heart emitting blue light. The water heart was suspended in the center of the cave, surrounded by a powerful energy barrier, which seemed to be protecting it.

Lu Fei and Naruto approached the Water Heart cautiously, trying to break through the energy barrier. They gathered their respective powers together and attacked the energy barrier. After some effort, the energy barrier was finally broken, and Lu Fei reached out and grabbed the Water Heart.

The Heart of Water felt cold to the touch, and he could feel the powerful force of water element contained in it, as if it could control the power of the entire lake.

"We did it!" Naruto said excitedly.

"Well, let's go, let's leave here first." Lu Fei said.

They floated out of the lake with the Heart of Water and returned to the shore. When the water elf saw the Heart of Water in their hands, a gratified smile appeared on his face.

"You really did it. This Water Heart will help you become stronger in protecting the continent." said the water elf.

"Thank you for your help. Without you, it would be difficult for us to find the Heart of Water." Lu Fei said gratefully.

The water elf smiled and shook his head, saying: "This is what you deserve. I hope you can make good use of it and make greater contributions to protecting the continent."

After saying that, the water spirit's figure gradually disappeared into the lake, leaving only Lu Fei and Naruto standing on the shore, holding the Heart of Water in their hands, their hearts filled with joy and anticipation.

They carefully put away the Heart of Water and continued walking deeper into the forest.
