I will use the ninja world to aid my cultivation of immortality.

"Thunder Magic - False Darkness!"

As soon as the shuriken and kunai attack ended, Naraku, who was standing still, did not stop. Instead, he suddenly clasped his hands together and unleashed a violent burst of lightning.

Crackling!

Terrifying arcs of electricity leaped from Naraku's palms, then converged into a sharp spear of lightning, which shot forward like a beam of light.

Boom! Boom! Boom!

In front of Naraku, there was not nothing but a dense forest.

As the Thunder Spear hurtled down, all the trees in its path were smashed to pieces with unstoppable force.

The air blast was howling.

After shattering numerous trees, the Thunder Spear finally reached a boulder five or six meters high a hundred meters away.

In an instant, amidst a deafening explosion, the boulder was blasted into dust by the Thunder Spear.

A wisp of smoke rose.

When the lightning spear dissipated, a passage six or seven meters wide and over a hundred meters long appeared in front of Naraku.

Even the land below was sunken, and the soil was scorched black by the lightning.

"I'm becoming more and more proficient at using ninjutsu with true qi, and the practicality in combat has also been greatly improved by reducing the number of hand seals."

Naraku was quite satisfied with the power of 'False Darkness'.

"False Darkness" was originally a B-rank ninjutsu.

Although the level of ninjutsu comes from the difficulty of training.

However, the difficulty of mastering a proper ninjutsu is often proportional to its power.

Especially combat-oriented ninjutsu.

If the power of a ninjutsu is lower than its difficulty in cultivation, then that ninjutsu is definitely a failure and has no significance in being passed down.

The power of 'False Darkness' undoubtedly matches the cultivation difficulty of Rank B.

However, the "Thunder Art: False Darkness" that Naraku is currently using has clearly exceeded the B-rank level and has risen to the A-rank level, or even comparable to the S-rank in power.

This situation naturally arises from the presence of true qi.

After testing how to use true qi instead of chakra to perform ninjutsu, Naraku clearly did not stop there, but attempted to develop it further.

Now, the most obvious change is that Naraku has been able to reduce the size of his hand seals. He can unleash his ninjutsu simply by bringing his palms together.

This achievement was made possible by two factors: firstly, true qi is easier to change in nature than chakra; and secondly, by the enhanced comprehension brought about by the nameless technique.

Although Naraku is only at the first level of Qi Refining, his comprehension is also gradually improving with the help of the nameless technique as his cultivation level increases.

This made him more adept at cultivation.

Chapter 13 Ninja System

"Given my current situation, if I go all out, becoming a Jonin would be no problem at all." Naraku assessed his own strength.

True Qi is far more powerful than Chakra.

Even though his cultivation level is still low, the resulting increase in strength is still very significant.

Moreover, as he cultivated immortality, Naraku also discovered that as his cultivation level improved, his five senses and reaction speed were gradually enhanced.

Even without considering his true energy, his strength has already improved considerably compared to before.

In the Naruto world, the power levels can be roughly divided into Genin, Chunin, Jonin, and Elite Jonin.

As for Special Jonin, the strength of this level is rather vague.

Some are support-type, meaning they possess a special skill in addition to their Chunin-level abilities.

Some are combat-oriented, with strength comparable to Jonin, but their overall abilities are not as comprehensive as those of Jonin.

Therefore, the terms Genin, Chunin, Jonin, and Elite Jonin can encompass the entire ninja system.

Yes. This refers to the conventional combat force system.

The Otsutsuki belong to a different system and need to be calculated separately.

Let's return to the conventional combat force system.

Starting as a Jonin means you've already entered the upper echelons of this world.

Above that, there are elite Jonin, who are already at the top level.

Incidentally, there is no such thing as a "Kage-level" character in this world.

"Kage" is simply the title used by the five great ninja villages to refer to their leaders.

Even after losing his position as leader, the Kage is still an elite Jonin.

Of course, the skill gap between elite Jonin is also quite large.

Based on his memories of his past life, Naraku devised his own set of beliefs.

He divided elite Jonin into three stages.

The first stage consists of ordinary elite Jonin.

Kakashi and Zabuza, who were at the beginning of the story, belong to this category.

The second stage is for the best among the elite Jonin.

The Fourth Kazekage of Sunagakure, Rasa, Pakura, and Orochimaru and Jiraiya in the present day belong to this category.

The third stage represents the pinnacle of elite Jonin.

Characters like the Third Raikage and the Third Tsuchikage, who could single-handedly command an army, belong to this category.

Naraku has not actually fought against any elite Jonin yet.

Of course, this is a good thing in some ways.

After all, with his original strength, if he had encountered an opponent of the level of an elite Jonin, he would probably have been dead long ago.

As for now.

Although they haven't fought yet, Naraku felt that he should be able to put up a fight against the elite Jonin of the first stage.

"Especially after I break through!" Naraku silently added to his mind.

That's right, he's about to have a breakthrough.

Nearly a month has passed since he created the True Qi Shadow Clone Cultivation Method.

At this moment, his cultivation had reached the perfect level of Qi Refining, and he was about to break through.

Once the breakthrough is successful, not only will his cultivation level be significantly improved, but he will also undergo a transformation in all aspects, including his five senses.

He already knew this from the knowledge of cultivation recorded in the "Secret Manual of Immortal Cultivation".

It can be said that every breakthrough on the path of cultivation is a sublimation of life, bringing about a transformation in one's entire being.

Naraku was very much looking forward to this.

"Even though it's a shared training ground, as a ninja, don't you know you should keep your distance when others are training?"

Suddenly, Naraku turned to look at a large tree not far away and said in a calm tone.

After a brief silence, a young figure emerged from behind a large tree not far away.

"Sorry, I just heard the commotion and came over to check it out," the boy said as he emerged from behind the tree.

"By the way, I don't think I've ever seen you before. What's your name?" The boy stared at Naraku and then asked another question.

His gaze swept over the nearby messy area.

Judging from the commotion just now, it's clear that this place has just experienced extremely powerful ninjutsu destruction.

"Only an A-rank ninjutsu could cause this kind of damage."

The boy silently added a sentence in his mind.

After all, that somewhat frightening passage on the other side was clearly formed in one go.

Such a powerful ninjutsu is not something that an ordinary person can master.

In his knowledge, there was absolutely no one in the village who could master this level of ninjutsu, not the person in front of him.

Naraku looked at the boy who walked out, feeling somewhat surprised.

Because he knew the other person.

A head of silver hair, and a mask that covered most of her face.

The boy who suddenly barged in was none other than Kakashi Hatake.

"The village is very big, isn't it normal to have people you don't know?"

Although Kakashi's appearance was somewhat unexpected, Naraku's emotions did not fluctuate much, and he replied calmly.

It's normal for the other person not to recognize you.

After all, he had always stayed in the Root organization, and even after entering the Ninja Academy, he could be said to have lived a very secluded life.
