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

Naraku is an unremarkable member of the Root organization, whose only highlight might be his beautiful 'partner' named Yakushi Nonou.

The above is Naraku's resume before he turned eighteen.

After he turned eighteen... he stopped eating beef!

Awakening his innate wisdom and discovering his destined connection to immortality, Naraku transforms from a ninja into a cultivator.

Chapter 1 Under the Light

“The village needs light, but it needs darkness even more. From today onward, you are the darkness beneath the light, and the roots under the shadow of the great tree that is the village.”

"Yes!"×100.

"Three years. You have been members of the Root's training program for three years, but I want to tell you that the real training has only just begun."

From now on, in addition to doubling your training volume, you must take this medicine every day; it will bring you greater strength.

Furthermore, until promotion to reserve member, a monthly elimination system will be implemented; those eliminated will not be eligible to become members of "Root."

"Yes!"×100.

"Very good. After rigorous training, you have all become qualified training program members. From now on, until you reach adulthood, you will be eligible to participate in the annual assessment. Those who pass the assessment can be promoted to reserve members."

"Yes!"×40.

"Number 1, congratulations on your successful promotion to reserve member. You are now qualified to have a real codename. What codename do you plan to choose for yourself?"

".ghost!"

"Demon? I remember your name was Naraku, right? The code name Demon suits your name quite well."

"Thank you!"

"Alright, now that you have a code name, let's begin the final ceremony!"

"What ceremony?"

"The Seal of Eradicating the Root of Tongue Disaster!"

"what!!!"

A piercing scream echoed in the dark, secret room.

Konoha!

Ninja Academy, First Year Teachers' Office.

"Have you all heard? Uchiha Shisui from Class A has submitted his application to graduate early."

"Oh! Really? First graders have only been in school for three months."

“Ordinary students definitely won’t do, but isn’t this Uchiha Shisui? You’ve all seen his performance before. Not to mention upperclassmen, even some genin might not be as good as him.”

“That’s true. I remember Uchiha Shisui is only five years old now. Isn’t that just like Hatake Kakashi back then? If he passes the test, wouldn’t he break Hatake Kakashi’s record as the youngest genin?”

"Now that you mention it, it's true. Kakashi Hatake graduated early, more than half a year after enrolling. Shisui Uchiha is going to break records."

"Hehe, after all, they are from the prestigious Uchiha clan. Although the people of this clan are mostly arrogant, their talents are indeed incomparable to those of us commoners."

Inside the office, a group of teachers were having a lively discussion.

Some expressed their feelings with admiration, while others made sarcastic remarks.

At this moment, a teacher wearing glasses couldn't help but start talking to another teacher at the opposite table.

"Naraku, do you think Uchiha Shisui will be able to pass the test?"

Sitting opposite me was a teacher called Naraku. Compared to the other teachers in the office, he looked much younger, only about seventeen or eighteen years old.

In addition, he was also very handsome, with an outstanding appearance.

Naraku was busy preparing his lesson and wasn't participating in the discussion, but when his colleague at the opposite table specifically asked him, he politely looked up at him.

“I think there’s still a good chance, after all, Uchiha Shisui’s excellence is obvious to all,” Naraku replied earnestly.

"That's true. It seems Kakashi's record is really going to be broken." The bespectacled teacher thought back for a moment and couldn't help but sigh.

Compared to Naraku, who had only been working at the ninja academy for half a year, Glasses-sensei had been working at the academy for over a decade.

I naturally taught Kakashi three years ago.

Compared to Kakashi back then, Glasses-sensei has to admit that Uchiha Shisui seems to be even better now.

Returning to Naraku.

After a brief chat with the bespectacled teacher about Uchiha Shisui, he quickly lowered his head again to continue preparing his lessons.

Yes, at least on the surface.

"I didn't expect that Uchiha Shisui had such an experience. However, given the Uchiha clan's atmosphere of striving to be the best in everything, even if Uchiha Shisui himself didn't want to do it, his clan would probably require him to do so."

Naraku twirled the pen nimbly, pondered for a moment, and then stopped thinking about it.

Given his current situation, he doesn't have the extra energy to care about others.

Pretending to be busy, Naraku patiently waited for the end of his workday, just like always.

Jingle Bell……

Time unknowingly came to evening.

Suddenly, the school bell rang, and the entire ninja academy became lively.

Students from all grades ran out of the school with great excitement.

The same goes for the teachers.

One by one, they seemed to have been relieved of a heavy burden, and left in twos and threes with relaxed expressions.

Naraku did the same, but instead of leaving the school, he found a secluded corner.

"untie!"

After confirming that no one was around, Naraku formed a hand seal in front of him, and in an instant, with a bang, he disappeared completely.

This was just a shadow clone.

Inside an apartment in the Konoha residential area.

The light of the setting sun shone through the window onto the bed.

On the bed was a black-haired young man sitting cross-legged with his palms facing upwards.

This person was none other than Naraku.

Suddenly, as the shadow clones of the Ninja Academy dissipated, Naraku, who had been sitting cross-legged on the bed with his eyes closed, slowly opened them.

"It's already time to get out of school. Time really flies," Naraku thought to himself, then closed his eyes again.

There's no other way; this is a crucial period for cultivation.

After persisting for half a year, following the successful completion of 'calm mind', 'concentration' is also about to reach its successful completion.

Once he has achieved perfect concentration and mental focus, he can sense and absorb the spiritual energy of heaven and earth, thus becoming a cultivator.

That's right.

Using shadow clones to take charge of ninja academy affairs was not just a way for Naraku to slack off, but rather a way to create more time for training.

Most importantly, what he practiced was not the ninja method that circulated in this world, but the method of cultivating immortality.

Naraku is a cultivator, and he is also a transmigrator.

However, unlike most transmigrators who possess other bodies, he was reincarnated into the present world.

About half a year ago, an unexpected experience awakened his memories of his past life.

In his past life's memories, the ninja world he now inhabits is merely a product of an anime.

Of course, this is not the most important thing. What is important is that along with the awakening of his past life memories, a bronze tower also appeared in his mind.

After he processed his past life memories and resonated with the bronze tower in his mind, he realized that the bronze tower was his cheat code as a transmigrator.

Chapter 2 The Gate to Immortality

Like Naraku, the Bronze Tower is a product of another world, and is suspected to be a treasure passed down by a sect in a certain cultivation world.

As for why the Bronze Tower appeared in his mind, Naraku was not sure at the moment.

After all, the bronze tower did not demonstrate any wisdom; all it left him was a legacy concerning the path of cultivation.

However, one thing is certain: the bronze tower was an incredible opportunity for him.

The bronze tower has nine stories.

After discovering the bronze tower, Naraku could enter the tower in human form by concentrating his mind.

This process is similar to the consciousness of a Jinchuriki entering the sealed space of the Tailed Beast within their body.
