Naruto: Can't learn ninjutsu? I'll just practice immortality!

After having supper and returning home, Naoki Asakawa did not start practicing directly, but first used a defective sword to cut off the outer shell of the sword, revealing the chakra metal contained in it.

"Although there is not much, it should be able to make two flying swords."

Naoki Asakawa compared it and said that if a flying sword made entirely of chakra metal was made into a two-centimeter-wide and twelve-centimeter-long sword, it would be able to make almost two.

In fact, there is another way, which is to mix chakra metal with ordinary metal, so that it is not a problem to make dozens of flying swords.

But the sword control technique does not control a disposable flying sword, but a recyclable flying sword.

In terms of power, the flying sword mixed with chakra metal is definitely not as powerful as the flying sword forged entirely from chakra metal.

So why did Naoki Asakawa choose to reduce the power? Is it just for convenience?

"However, I'm afraid I'll have to trouble Mikoto to forge the flying sword."

The chakra metal worth millions of taels, Naoki Asakawa was still a little worried about asking the owner of the ninja tool shop to help forge it.

If Uchiha Mikoto comes forward and asks the craftsmen of the Uchiha clan to forge it, it should be much safer, at least there will be no cutting corners.

After the two flying swords are formed, he will engrave the array pattern for the flying swords, and then use the magic power to nourish them for a period of time before he can use the sword-controlling technique.

"Let's practice first."

"Refine the essence into qi!"

"Samadhi True Fire!"

Asakawa Naoki sat cross-legged, practicing the basic Qi Refining Technique and Samadhi True Fire at the same time. Dinner and supper were being quickly digested into essence.

The next morning, when Asakawa Naoki opened the door, he happened to meet Uchiha Mikoto who was going to school, and told Mikoto about asking him to forge the flying sword.

In the face of Asakawa Naoki's request, the latter also readily agreed.

With the help of the craftsmen of the Uchiha clan, two flying swords with chakra metal as the main body and a small amount of other hard metals were forged.

In the following time, Asakawa Naoki's life fell into peace again.

I get up early every day to go to school with Uchiha Mikoto, go home to practice after school in the afternoon, and occasionally go out to play or go shopping with Mikoto and Kushina on weekends.

After nearly two years of such a peaceful life, the time came to March of the 37th year of Konoha.

March in the ninja world should be a period of vitality and competition for all things.

But at this time, Konoha, or the entire ninja world, was a little restless.

Twenty years ago, due to the tragic First Ninja World War, the five major countries each paid a heavy price and signed a "truce treaty" together.

After that, although there were constant wars in the ninja world, there has never been a large-scale war like the First Ninja World War in which all five major countries were mobilized. Most of the time, it was a small war and friction.

The ninja world also ushered in a short peace.

But today, twenty years after the First Ninja World War, with the development of twenty years, the economic gap between the five major countries has gradually increased.

Because of economic problems, the fighting forces of various countries have gradually risen to control the country and the ninja village, and pursue the use of force to expand the country's territory.

In this environment, even Konoha Village, located in the heart of the Land of Fire, gradually became nervous.

On the streets of Konoha, ninjas that were rarely seen at ordinary times began to become common, and the whereabouts of ninjas were also unusually hurried. They often had to go out to do missions again just a few days after returning.

A large number of ninjas were transferred to the front line, resulting in a large reduction in the number of ninjas in Konoha Village.

The missions that were originally needed to be rushed to do were no longer in demand because of the large reduction in ninjas.

In this case, the graduation season of the Ninja School was approaching. In addition to the sixth-grade students who were about to graduate, many lower-grade students also applied for early graduation.

Asakawa Naoki and Uzumaki Kushina were no exception.

Although he had just turned ten not long ago, he should have been promoted to the fourth grade of the Ninja School in April and studied in the Ninja School for another three years before graduating.

But Asakawa Naoki, who was familiar with the plot of Naruto, knew that the Second Ninja World War was coming.

If he did not graduate now, as the war continued, he might be forced to graduate and go to the front line if he continued to stay in the Ninja School.

It would be better to graduate early and get familiar with actual combat before the intensity of the war reaches its peak, so as to avoid encountering the most intense time of the war when he first goes to the battlefield.

Another reason is that Asakawa Naoki has spent all his savings, and he may not have money to eat if he continues to stay in the ninja school.

He needs to graduate and become a ninja to earn money to eat, otherwise the speed of refining essence into qi will definitely be affected.

Moreover, he has the confidence to become a ninja.

After nearly two years of training, the mana in his body has increased by more than several times.

Although he has not yet broken through the late stage of refining essence into qi, he feels very close.

The opportunity for breakthrough is tonight!

......

And in the Hokage's officeIn the room, Hiruzen Sarutobi sat at his desk with a melancholy look on his face, feeling the surging atmosphere, and his memory could not help but go back to that night twenty years ago.

Within the borders of the Land of Lightning, a ninja team was fleeing frantically.

This ninja team was not large, with only six people in total.

But even these six people, each of them was a well-known ninja in Konoha.

Needless to say, the leader of the six-man team, with white hair, a burly figure, a Konoha forehead guard with a visor on his head, and a blue armor, was injured but still expressionless, and was the second generation Hokage of Konoha, Tobirama Senju.

The other five people were of similar age, and there were both ninja geniuses and civilian geniuses, namely Hiruzen Sarutobi, Danzo Shimura, Mito Kado En, Koharu Utatane and Tofu Akimichi.

All five were members of the Tobirama class taught by the second generation Hokage, Tobirama Senju.

However, compared to the expressionless Senju Tobirama, the five people all had sadness and a little despair in their eyes.

There were more than five people in their Tobirama class, but the youngest Uchiha Kagami stayed in the Land of Lightning forever because he covered their retreat.

Originally, they entered the Land of Lightning secretly this time to sign a peace agreement between the Land of Lightning and the Land of Fire with the Second Raikage, but somehow the news was leaked to the fighting faction of the Cloud Village.

When the Second Raikage and the Second Hokage were preparing to sign a peace agreement, the fighting faction leaders of the Cloud Village, Kinkaku and Ginkaku, directly led a large number of fighting ninjas into the conference hall.

If Kinkaku and Ginkaku had not scolded the Second Raikage for being a traitor to the Cloud Village and severely injured the Second Raikage first, they would have suspected that the Second Raikage and Kinkaku and Ginkaku had conspired to catch the turtle in the jar.

But now, even if they sacrificed Uchiha Kagami and escaped from the conference room, their situation is still not optimistic.

The strongest fighter and backbone of the Tobirama team, Senju Tobirama, was not only severely exhausted when saving them, but also suffered serious injuries.

In fact, if the second generation Hokage Senju Tobirama wanted to escape, it would not be difficult, after all, he was the fastest in the ninja world with the Flying Thunder God Technique.

Although injured, it is not impossible to escape.

The real difficulty is how to let the five of them escape.

Judging from the current situation, if the five of them want to escape, I am afraid that someone must stay behind to cover their retreat.

Those who retreat may not be able to return to Konoha alive, but those who stay behind will almost certainly die.
