Naruto Bond

After receiving the mysterious letter, Lu Fei knew that they needed a stronger force to face the upcoming huge conspiracy. After careful consideration, Lu Fei decided to start practicing the Eight Gates.

Lu Fei found a quiet place and prepared to devote himself to this arduous practice. He closed his eyes, adjusted his breathing, and calmed his mind.

When he opened his eyes again, they were full of determination.

Lu Fei first began to practice the first gate - opening the gate. He concentrated his mind, felt the flow of chakra in his body, and tried to break through the first limit.

"Ah!" Lu Fei yelled, his muscles tensed and sweat dripped from his forehead. He could feel a strong resistance, but he gritted his teeth and held on desperately.

After some effort, Lu Fei finally broke through and opened the door, and a powerful force instantly filled his body.

"Is this the power to open the door?" Lu Fei felt the changes in his body, feeling both excited and nervous.

But he knew that this was just the beginning and the next door would be more difficult.

Then, Lu Fei began to attack the second door - the rest door. This time the resistance was greater than when he opened the door, and his body began to tremble, and the feeling of pain spread throughout his body.

"Can't give up!" Lu Fei encouraged himself in his heart.

He kept adjusting the movement of chakra, trying again and again. Finally, the gate of rest was opened, and Lu Fei felt a sense of fatigue, but at the same time he could also feel the further improvement of strength.

As his training deepened, Lu Fei came to the third gate - the Gate of Life. This gate was much more difficult than the previous one, and Lu Fei needed to put in more effort and patience.

His body felt like it was being torn apart, but he still didn't give up.

"I must succeed!" Lu Fei roared.

After countless attempts, the Life Gate was finally breached. Lu Fei was exhausted at this time, but he did not rest, but immediately began to attack the fourth gate - the Injury Gate.

The practice of the Injury Gate put Lu Fei into extreme pain. Every muscle of his was trembling and every nerve was screaming.

Sweat was pouring down like rain, Lu Fei's face turned pale, but his eyes became more determined.

"Almost there, just a little bit more!" Lu Fei kept encouraging himself.

He mobilized all the chakra in his body and launched a final attack on the shackles on the injured gate.

"Open it for me!" Lu Fei roared.

Finally, when he was about to faint, the wound slowly opened.

An unprecedented powerful force instantly filled Lu Fei's body, but at the same time, he also felt extreme fatigue and exhaustion.

Lu Fei collapsed to the ground, gasping for breath.

"Finally, we've reached the fourth door..." Lu Fei muttered to himself, but a relieved smile appeared on his face.

Lu Fei collapsed to the ground, breathing heavily, his clothes soaked with sweat. But he knew that now was not the time to rest.

After a while, Lu Fei stood up with all his strength and began to feel the change in power after the fourth gate, the "Injury Gate", was opened. He could feel the chakra in his body like a surging torrent, powerful and difficult to control.

"I must adapt to this power as soon as possible, otherwise I won't be able to unleash its true power in battle." Lu Fei said to himself.

He began to practice some simple movements, trying to get his body used to this powerful output. Every movement was accompanied by the sound of wind, and the leaves around him rustled in the airflow he created.

However, the adaptation process was not smooth. Lu Fei almost fell several times due to improper strength control, but he never gave up.

"I can definitely do it!" Lu Fei gritted his teeth and persisted.

After several hours of practice, Lu Fei was gradually able to control this power more easily.

"It's almost done. Next we need to try out its effect in actual combat." Lu Fei looked determined.

He found an open field and set up some targets.

Lu Fei took a deep breath, opened the "Injury Gate", and then rushed towards the target.

"Boom!" A powerful force exploded instantly and the target was smashed to pieces.

A satisfied smile appeared on Lu Fei's face, but he also knew that this was only a preliminary result.

In the following days, Lu Fei continued to carry out more complex and high-intensity training. He conducted simulated battles with other ninjas and constantly honed his skills in using the power of the "Injury Gate" in actual combat.

Once, when fighting against a powerful ninja, Lu Fei opened the "Injury Gate" at the critical moment, instantly turning the situation around and successfully defeating his opponent.

"It seems that my practice has paid off." Lu Fei was secretly happy.

But he also understood that the practice of Eight Gates Ninjutsu was far from over, and he had to move to a higher level.

One day, when Lu Fei was training, Naruto, Sasuke and Haruno Sakura came to him.

"Lu Fei, you are training too hard!" said Naruto.

Lu Fei smiled and said, "There's nothing I can do. To cope with the upcoming crisis, this little effort is nothing."

Sasuke nodded: "But you also have to take care of your body and don't push yourself too hard."

Haruno Sakura handed him a bottle of water: "Drink some water and take a rest."

Lu Fei took the water and took a sip: "Thank you, I will pay attention. But we all need to keep getting stronger to protect the village."

Everyone smiled at each other, their eyes full of determination.

Lu Fei continued to practice the Eight Gates of Dunjia. He knew that the future battles would be more difficult, and he had to be fully prepared...

Lu Fei continued to devote himself to the practice of the Eight Gates Ninjutsu, his body and mind immersed in the pursuit and control of power.

One day, when Lu Fei was practicing, he suddenly felt a strange fluctuation in the chakra in his body. He stopped and felt the fluctuation carefully, and a sense of doubt surged in his heart.

"What's going on? Is this a backlash from excessive practice?" Lu Fei worried secretly.

He decided to stop practicing temporarily and go to the village elders for advice.

After listening to Lu Fei's description, the elder pondered for a moment and said, "This may be a normal reaction when you break through the bottleneck of strength, but you can't take it lightly. I suggest that you pay more attention to inner peace and harmonious resonance with chakra when practicing."

Lu Fei nodded, thanked the elder and returned to his place of practice.

He adjusted his training method according to the elders' advice. Before each training session, he would first calm down and clear his mind, and then slowly open the Eight Gates.

As time went by, Lu Fei gradually adapted to the changes in the chakra in his body, and he became more proficient in controlling the "Injury Gate".

However, Lu Fei was not satisfied with this. He knew that just opening the fourth door was far from enough, and he wanted to challenge a higher level.

So, Lu Fei started attacking the fifth gate "Du Men" again.

This time the difficulty was greater than before, and every attempt made him feel as if his body was being torn apart. But Lu Fei persisted again and again with his tenacious willpower and firm belief.

"I will definitely be able to break through!" Lu Fei kept encouraging himself in his heart.

After countless failures and setbacks, Lu Fei finally found the trick to open "Du Men".

On a quiet night, Lu Fei's chakra surged violently, and he roared, "Dumen, open!"

In an instant, an even more powerful force burst out, and the surrounding air began to fluctuate because of this force.

Lu Fei felt this new power, and his heart was filled with joy and a sense of accomplishment. But he also knew that this was just a small step forward, and there would be more challenges waiting for him in the future.

In the days that followed, Lu Fei consolidated his mastery of "Du Men" while continuing to explore the deeper levels of the Eight Gates.

Naruto, Sasuke and Haruno Sakura are also working hard on their training. They often exchange their training experiences with Lu Fei and encourage and support each other.

Outside the village, the unknown threat is gradually approaching...
