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

The death of a parent.

The brutal experiences within the root organization.

All of this made Naraku feel not only no affection for Konoha, where he had lived for more than ten years, but rather a deep aversion to it.

The reason he deliberately devoted his energy to studying sealing techniques was actually to find a way to break the "Seal of the Extinction of the Tongue".

Cursed seals are a branch of sealing techniques.

Naraku knew very well that only by eliminating the "Seal of the Extinction of the Tongue" could he hope to gain freedom, leave, and even destroy this place that he loathed.

However, the "Seal of the Extinction of the Tongue" is clearly not so easy to break.

In particular, the sealing techniques that Naraku was able to learn all came from the Root organization.

Although Danzo was very generous in investing resources in Root in order to better cultivate his own armed forces, he was not without limitations.

The accessibility of common techniques like ninjutsu, taijutsu, and genjutsu within the Root organization is extremely high.

Let alone low-level techniques like D and C, even high-level techniques like B and A can be freely accessed within the Root organization.

However, special techniques like sealing techniques have a relatively low degree of openness.

Clearly, Danzo wasn't an idiot.

The other party knew that the key to controlling the root organization was the "Seal of the Extinction of the Tongue".

Therefore, special attention will be paid to the spread of sealing techniques to prevent anyone from breaking the "Seal of the Root of Tongue Calamity" through sealing techniques.

Even though the possibility is extremely slim, precautions have not been relaxed.

This is why, even though Naraku painstakingly studied all the sealing techniques he could obtain, he never made much progress in breaking the "Seal of the Extinction of the Tongue".

Even half a year ago, he was so unwilling to give up that he tried to forcefully break the seal, which resulted in the "Seal of the Extinction of the Tongue" being triggered, and he almost lost his life.

However, it was this experience that, perhaps due to the stimulation of his brain by the "Seal of the Root of Tongue Disaster," unexpectedly awakened his past life memories, thus granting him a new life.

"According to the records of the cultivation method, after entering the Qi Refining stage, one will develop divine sense. In addition to exploring the outside world, divine sense can also introspect. At that time, one may be able to use divine sense to understand the 'Seal of the Root of Tongue Disaster'."

Naraku stared at the mirror, which had become blurred again by the mist, withdrew his tongue, his expression returned to calm, and he turned and walked out of the bathroom.

Naraku sat cross-legged on the bed.

However, he did not rush to start cultivating. Instead, he focused his mind and sensed the bronze tower in his mind.

A short while later, an ancient bronze tower appeared in Naraku's mind perception.

When his consciousness came into contact with the bronze tower, it was immediately drawn to it.

In a dizzying moment, Naraku's consciousness materialized and appeared in a spacious hall.

The main hall was not decorated much, with a pillar of light running straight up to the top in the center.

Meanwhile, in front of the beam of light, there were three jade spheres emitting a soft glow.

The main hall before us is the first level of the bronze tower.

Naraku was naturally familiar with the situation inside the main hall.

He took a step and walked towards the central pillar of light.

"Now that I have embarked on the path of immortality, I wonder if I can enter the pillar of light!"

Thinking this to himself, Naraku walked up to the pillar of light and raised his hand to press it against the pillar.

The pillar of light is the passage to the next level.

Only by entering the pillar of light will you be teleported to the next level.

Chapter 6: Inheritance! The Assessment!

When Naraku's palm touched the beam of light, he immediately felt a strong resistance.

Naraku was alarmed and focused all his energy on breaking through the barrier.

Even when he pushed his true energy to its limit, he still couldn't break through the resistance of the beam of light.

This result clearly proves that with his current cultivation level of just entering the first stage of Qi Refining, he is not qualified to enter the second level of the Bronze Tower.

"It seems it's still not working, but I can feel that the resistance has indeed decreased a bit. If this continues, as long as I continue to improve my cultivation, I will be able to enter the next level sooner or later and obtain more cultivation inheritances."

Naraku withdrew his hand with some disappointment.

When he first entered the bronze tower, he naturally tried to enter the pillar of light.

The resistance to the beam of light that time was even greater than it is now.

The disappointment didn't last long; Naraku quickly regained his composure.

Although they still failed to enter the beam of light this time, the reduced resistance undoubtedly proved the method of entry into the beam of light.

That means he needs to have a higher level of cultivation.

He has now successfully embarked on the path of cultivation.

All that's left is to work hard to improve your cultivation level, and sooner or later you'll be able to enter the pillar of light, reach the next level, and obtain more cultivation inheritance.

Thinking of the cultivation inheritance, Naraku glanced at the three jade spheres in front of the pillar of light.

These three jade spheres are the cultivation inheritance placed on the first floor of the bronze tower.

One of them is the nameless cultivation technique that Naraku is currently practicing.

The other two jade orbs contain the divine power known as the "Five Elements Technique" and the "Immortal Dao Secret Manual," which records a wealth of knowledge about cultivating immortality.

Naraku had already obtained the inheritance recorded in these three jade orbs.

So after testing the beam of light, he did not linger, but retreated directly from the bronze tower.

Consciousness returns to the physical body.

On the bed, Naraku slowly opened his eyes.

"My current cultivation level is still very shallow. Rather than diverting my energy to cultivating supernatural abilities, I should concentrate on improving my cultivation level, at least to the second level of Qi Refining!"

Leaving aside the "Immortal Path Secrets," it would be impossible for Naraku not to be envious of the supernatural powers inherited from the first level of the Bronze Tower.

After all, judging from the description of this supernatural power, even mastering just a part of it could greatly enhance his combat power.

However, things should be prioritized according to their importance and urgency.

With his current cultivation level, even if he wanted to force himself to cultivate, he would probably achieve half the result with twice the effort.

Having made up his mind, Naraku wasted no more time and immediately began to inhale and exhale spiritual energy to improve his cultivation.

Time flies.

Three days have passed quietly.

This day was just like the task assigned three days prior.

Naraku unsurprisingly became Uchiha Shisui's examiner.

Naraku was not surprised by this.

After all, given Danzo's power within the village, accomplishing these things would be by no means difficult.

In an empty classroom.

"Naraku-sensei, are you my examiner?"

At the front of the stage, a five-year-old boy with a round nose and a very young appearance looked at Naraku standing opposite him with surprise.

The boy was none other than Uchiha Shisui.

As a teacher who taught first-year students, Naraku naturally had contact with Uchiha Shisui, and they knew each other.

“That’s right, I am one of the examiners for this assessment. This is Teacher Ooyama, who is also your examiner.” Naraku looked at Uchiha Shisui opposite him, nodded with a smile, and introduced the other person beside him as well.

There was more than one examiner than Naraku.

Standing next to Naraku, Mr. Ooyama was also wearing a standard Chunin uniform.

However, compared to Naraku's youth, Daiyama appears to be a middle-aged man, and he looks very serious.

Ooyama was also a teacher at the Ninja Academy, but he was in charge of the upper-grade students, so Uchiha Shisui did not know him.

Hello, Teacher Dashan!

Under Naraku's introduction, Uchiha Shisui behaved very politely and immediately bowed to Mount Daisan.

"Hello there!"

Daizan nodded slightly in response to Uchiha Shisui's bow.

Then he said with a serious expression, "Uchiha Shisui, as an early graduation assessment, the assessment method is much stricter than the normal graduation assessment. In the next assessment, in addition to facing theoretical assessments, you will also need to fully master the Three Body Techniques and undergo practical combat assessments."

"Yes, I will try my best to complete the assessment!" Uchiha Shisui's youthful face showed a serious expression.

It was clear that, whether it was voluntary or compelled by his family, he took this assessment very seriously.

"Naraku-sensei, let's begin!"

"Alright, let's begin the assessment!"

Ooyama was very satisfied with the attitude shown by Uchiha Shisui.
