Naruto Bond

After crossing the river, Lu Fei and Naruto continued their arduous trek through the forest. The trees around them became denser and denser, with branches and leaves intertwined, almost completely covering the sky. Only a few faint rays of light barely penetrated, casting mottled shadows on the ground.

Suddenly, a dull sound of footsteps came from the front, and each step was accompanied by a slight vibration of the ground. Then, a forest guardian as huge as a mountain appeared in their sight. This guardian looked like an ancient beast, covered with a thick rock-like shell, and its skin was covered with mysterious green lines, as if it contained endless vitality. Its head was huge and majestic, its eyes were like burning green flames, exuding a chilling breath, and its mouth had sharp fangs, each of which was more than a person tall.

"How dare you, a tiny intruder, set foot in the core holy land of this forest? Prepare to be punished!" The guardian let out a deafening roar, and the sound waves spread out in all directions like a substance, shaking the surrounding trees rustling, and some fragile branches were even broken directly.

Lu Fei unleashed the "Flame Lightning Slash" without hesitation. The power of lightning and fire gathered on the sword, turning into a dazzling sword light and slashing towards the guardian. However, when the sword energy hit the guardian's body, it only splashed a few weak sparks on its hard shell, failing to cause any substantial damage to it.

Seeing this, Naruto quickly performed the Shadow Clone Technique. In an instant, countless shadow clones filled the surrounding space. They rushed towards the guardian like a tide, trying to interfere with its actions. The original Naruto quickly formed hand seals on the side, preparing to perform a powerful ninjutsu to hit it hard. "Senjutsu? Wind Style? Nine-tailed Rasenshuriken!" Naruto shouted, and after the huge Rasenshuriken took shape in his hand, it immediately flew towards the guardian. The Rasenshuriken continued to grow larger during the flight, and the powerful force brought a gust of wind, uprooting the surrounding trees and engulfing them. But when it hit the guardian, it only made the guardian shake slightly, as if it was just touched by a fly.

During the fierce battle, Lu Fei carefully observed the guardian's every move and found that every time it swung its huge arms to attack, a brief fluctuation of energy would appear at the connection between its arm and shoulder, and the defense there seemed to be relatively weak.

"Naruto, attack the connection between its arm and shoulder, that's the weak point!" Lu Fei shouted loudly, his voice still clearly audible amid the fierce battle.

After hearing this, Naruto immediately ordered his shadow clones to change the direction of attack. All the shadow clones rushed towards the connection between the guardian's arm and shoulder like a group of flexible ants. The real Naruto used "Senjutsu? Molten Release? Rasenshuriken". The high-temperature Molten Release Rasenshuriken flew towards the vital part with blazing flames. After the Molten Release Rasenshuriken hit the target, the connection between the guardian's arm and shoulder was instantly melted by the high temperature. It let out a painful roar, and the attack movement of its arm became slow.

Lu Fei seized this rare opportunity and used the "Flame Thunder Devil Slash", increasing the power of the Thunder Flame Sword to the extreme, and slashed at the injured parts of the Guardian's arm and shoulder with all his strength. This sword contained all of Lu Fei's strength and determination. The power of Thunder Flame exploded the moment it hit the Guardian, and the Guardian's arm and shoulder were completely cut off. Green blood gushed out like a fountain, spilling on the ground, splashing a blood mist.

After the guardian was severely injured, it roared even more angrily, and its other arm swung wildly, smashing towards Lu Fei and Naruto. At the same time, it opened its bloody mouth, gathering a powerful energy in its mouth, preparing to launch a more violent attack.

Lu Fei and Naruto did not dare to slack off. They cooperated with each other and continued to fight the guardian to death. During the battle, they found that the guardian's eyes would briefly flash before launching a powerful attack, which might be another vital part that could be attacked.

So, they adjusted their tactics. Naruto used a series of shadow clones to attract the guardian's attention, while Lu Fei seized the opportunity to use the "Flame Lightning Slash" and aimed directly at the guardian's eyes. After a hard fight, they finally succeeded in hitting the guardian's eyes. The guardian struggled in pain, and his huge body began to shake.

Finally, with their unremitting efforts, this powerful forest guardian fell to the ground with a bang, raising a cloud of dust. Its body gradually turned into countless points of light and dissipated in the air, as if it had never appeared.

Lu Fei and Naruto were panting heavily with exhaustion, but they knew that they couldn't stay here for too long. After a short rest, they continued to move towards the mysterious spring.

As they went deeper, the air around them became fresher and filled with a faint floral scent. In front of them, an area flashing with strange light appeared, and something seemed to be flowing slowly in the light.

"Could that be the mysterious spring?" Naruto said excitedly, his eyes gleaming with anticipation.

They quickened their pace and walked towards the light. When they got closer, they saw a clear spring. The spring water was crystal clear, and the bottom was covered with gems of various colors. These gems emitted a soft light, reflecting the spring water in a variety of colors. The spring water was constantly bubbling, and every time a bubble burst, it would release a mysterious energy that merged into the surrounding air.

"Finally found it!" Lu Fei said excitedly.

However, just as they were about to approach the spring, several elf-like creatures suddenly jumped out of the spring. These elves had small and exquisite bodies, transparent wings on their backs, and held a thin and long magic wand in their hands. Their eyes revealed vigilance and hostility.

"You can't get close to this sacred spring. It is the source of life for the forest and no one is allowed to violate it!" an elf who looked like the leader shouted.

Lu Fei quickly explained: "We have no ill intentions. We are here to find the power of the spring to strengthen the seal, prevent the release of the dark power, and protect this forest and continent."

After listening to Lu Fei's explanation, the elves looked at each other, but the hostility in their eyes did not disappear immediately.

"Why should we trust you? The power of this spring water is extremely strong. If it falls into the hands of evil people, the consequences will be disastrous." The elf leader questioned.

Naruto said: "We have gone through hardships along the way and defeated many minions of the dark forces just to find this place. We have the determination and ability to protect the power of the spring and will not let it be used by evil."

The elves were silent for a moment, seemingly thinking about what Lu Fei and Naruto said.

"Then we will test you. If you can pass the test, we will allow you to use the power of the spring." The elf leader finally said.

"What test? We accept it!" Lu Fei answered without hesitation.

The elf leader waved his magic wand, and the space around them changed instantly, and they were teleported to a mysterious space filled with various traps, including crystal columns that shot lasers, spikes that suddenly emerged from the ground, and flaming balls flying in the air.

"You need to pass through this trap area and reach the exit on the opposite side within the specified time to prove that you have enough ability and wisdom to use the power of the spring water." The voice of the elf leader echoed in the space.

Lu Fei and Naruto took a deep breath and stepped into the trap area carefully. They cooperated with each other, Lu Fei used the power of the Thunder Sword to cut off some dangerous traps, and Naruto used the Shadow Clone Technique to trigger some traps in order to find a safe route.

During the crossing, they encountered a huge laser array, with countless lasers crisscrossing and forming a seemingly unsolvable maze. Lu Fei carefully observed the emission pattern of the lasers and found that the lasers were emitted at a certain time interval and sequence. As long as he grasped this pattern, he might be able to find a safe path through.

"Naruto, follow me, follow my pace!" Lu Fei shouted, and then he saw the right moment and took the lead in stepping into the laser array, shuttling through the gaps in the lasers. Naruto followed closely behind, while the shadow clones watched the changes in the lasers around and reminded them in time.

After some difficult exploration and attempts, they finally succeeded in passing through the laser array. But there are more challenges waiting for them ahead. There is an area full of fire balls that automatically track targets. These fire balls are extremely hot. Once hit, the consequences will be disastrous.

Naruto used "Senpo-Wind Style-Nine-tailed Rasenshuriken" to create a strong airflow, trying to blow away the fireball. Lu Fei used "Flame Thunder Sky Slash" to smash the approaching fireballs one by one.

With their joint efforts, they finally approached the exit. However, just as they were about to step out of the exit, a huge mechanical puppet emerged from the ground and blocked their way.

This mechanical puppet is made entirely of metal, with blue light flashing at its joints. It holds two huge swords in its hands, and its eyes reveal cold murderous intent.

Lu Fei and Naruto quickly entered combat state. They knew that this was the final test. If they could not defeat this mechanical puppet, all previous efforts would be in vain.

Lu Fei used the "Flame Lightning Slash" and slashed at the mechanical puppet. The mechanical puppet easily blocked Lu Fei's attack with its sword, and then stabbed Lu Fei with its sword. Lu Fei dodged quickly and looked for the mechanical puppet's weakness.

Naruto performed the Shadow Clone Technique, and many of them rushed towards the mechanical puppet, trying to distract it. The real Naruto quickly formed hand seals on the side, preparing to perform a powerful ninjutsu to give it a fatal blow.

During the battle, Lu Fei discovered that every time the mechanical puppet launched an attack, there would be a brief energy fluctuation in its chest, which might be its vital part.

"Naruto, attack its chest, that's its weak point!" Lu Fei shouted loudly.

After hearing this, Naruto immediately ordered his shadow clones to change the direction of attack and attack the chest of the mechanical puppet. The real Naruto used "Senjutsu? Molten Release? Rasenshuriken", and the high-temperature Molten Release Rasenshuriken with blazing flames accurately hit the chest of the mechanical puppet. After the mechanical puppet's chest was hit, the energy fluctuations were instantly disordered, and its movements became slow.

Lu Fei took the opportunity to perform "Flame Thunder Demon Slash", increased the power of the Thunder Flame Sword to the extreme, and slashed at the chest of the mechanical puppet with all his strength. This sword successfully cut the chest of the mechanical puppet, and the parts inside the mechanical puppet were scattered all over the ground. It fell down with a bang and stopped moving.

As the mechanical puppet fell, the surrounding space gradually returned to normal, and they returned to the mysterious spring.

The elves smiled with relief when they saw that Lu Fei and Naruto had successfully passed the test.

"You have passed the test and proved your strength and determination. Now, you can use the power of the spring." said the elf leader.

Lu Fei and Naruto walked to the spring and gently touched the water with their hands. They felt the powerful force of the spring, which continuously flowed into their bodies, repairing their fatigue and pain, and also improving their strength.
