Natural Energy

Naraku pondered for a while, studying the alternate dimension and Ninjutsu. Time passed unnoticed, and the wooden barrel in the arena began to move.

Thump! Thump! Thump!

The wooden barrel shook and made a sound as it hit the floor.

Bang!

The wooden barrel's Sealing Tag was blown away, the barrel shattered, and black mist surged and spread, within which a figure could be vaguely seen. As the black mist dissipated, the figure gradually became clearer, with gray skin, long hair reaching the waist, and strangely, two extra arms growing from its shoulders.

"Hahahaha, this power! It's incredible!"

The death row inmate burst into excited laughter, then stared intently at the calmly seated Uchiha Nara.

Naraku calmly looked at the death row inmate in front of him. He had been sitting in the wooden barrel for about two hours. His originally short hair had grown longer under the influence of the Cursed Seal's energy, proving the Cursed Seal's rapid growth ability.

This ability indicates that the Cursed Seal also has excellent healing and restorative capabilities.

Call out!

The death row inmate, brimming with smug satisfaction, charged towards Naraku with incredible speed, his five fingers forming claws as he grabbed for Naraku's neck. His other three hands, one pair, reached for Naraku's shoulders, while the other clenched into a fist, gathering power.

Boom!

The office wall was cracked, and a figure was stuck to it in a starfish shape. The cracks in the wall were dense. The faster the condemned prisoner rushed, the farther he was thrown, and the heavier the force he endured.

Naraku lowered his leg after the side kick and returned to his calm demeanor.

Although the death row inmate's attack was fierce, it was controlled by Naraku's Sharingan eye technique. With a counterattack kick, the death row inmate seemed to be seriously injured and fell into a coma.

"Not bad, you've gotten much stronger. But you couldn't withstand a single move from me, so you haven't fulfilled your promise of release. Go to prison and repent for your crimes."

This death row inmate could not possibly be a match for Naraku.

From Naraku's Sharingan perspective, the energy within the death row inmate was unique and refined. Compared to the blue state of ordinary ninja Chakra, it was much more condensed and larger, and it seemed to have a special rhythm within it.

This unique rhythm gives people a very peculiar feeling; it's a type that Naraku has never seen in all his years of fighting—strange and mysterious.

"Chakra with abundant Natural Energy, indeed mysterious. But those extra hands, are they truly an uncontrollable mutation, as Orochimaru said...?"

Naraku's Sharingan observed these death row inmates when they were injected with Cursed Seal; they were just ordinary ninjas, only their wicked intentions led them to betray their unsuspecting companions.

This mysterious Chakra rhythm and Chakra quantity are not something a ninja like this could possess. If someone had this level of skill, they would have already made a name for themselves in Konoha.

As for the extra two hands, they made Naraku frown slightly.

"Chieftain!"

Naraku subdued the death row inmate, and after a short while of contemplation, the office door opened, and Uchiha Riki and many members of the Prison Division of the Security Department rushed in upon hearing the commotion.

The Cursed Seal on the unconscious death row inmate began to fade eerily, and the extra hands that had grown out disappeared along with the bright yellow and red color, shrinking back to the Cursed Seal on his shoulders.

"It's alright. Take this man back to his cell, and bring another death row inmate over. Go."

Naraku watched this scene, nodded slightly, and whispered his instructions.

"Hi!" X7

The Prison Division members, looking at the crack in the office wall and the unconscious figure within it, swallowed hard and dragged the death row inmate out.

A short while later, members of the Prison Division brought in another death row inmate.

Naraku used the Cursed Seal to activate the death row inmate's Chakra, then observed him for Sharingan. He then used the Awakening Heart Pill again to raise the death row inmate's Cursed Seal to state two.

He then used the Four Black Mist Formation and the Black Sealing Method Seal to turn the death Cursed Seal Level 2 Cursed Seal, into a fake death through Ninjutsu and drugs, successfully activating the Natural Energy of the Cursed Seal Level 2.

"Such immense power..."

The second death row inmate grew a strange single horn on his head. Like the previous one, he also wanted to take Naraku and escape, but in the end, he was Naraku in one move.

"That's right, Natural Energy. Their original Chakra was ordinary, but it was the Natural Energy they absorbed through the Cursed Seal that made their Chakra extraordinary, mysterious, and full of profound meaning!"

Based on these two examples, Naraku was able to confirm that as long as the Cursed Seal Level 1 was successfully cast, activating the Cursed Seal Level 2 was indeed very safe.

Furthermore, the Cursed Seal Level 2 gave Naraku a feeling of intense, mysterious energy.

The way the Cursed Seal utilizes Natural Energy is much faster than the Sage Mode of the Three Sacred Lands. As long as the Cursed Seal covers the whole body and the skin color changes, Natural Energy will continuously enter the body.

This method is more efficient and easier to use than the one used by the Three Sacred Lands, which requires long-term accumulation.

The drawback is that it lacks the supporting methods for utilizing Natural Energy and various Senjutsu found in the Three Sacred Lands Sites.

The eight death row inmates were quickly activated with their Cursed Seal Level 2 by Naraku. Two of them died unexpectedly while in their Cursed Seal Level 2 state. One had bones growing inside his body that pierced his own heart, while the other had a bump on his forehead that appeared to be a horn growing inside him that pierced his head.

The other six grew some strange limbs or extra ears and eyes. Although they were somewhat peculiar, they were still easily defeated by Naraku.

The six men did not meet the requirement of being able to withstand even one move from Naraku, so they could not be released. Naraku kept his word, but he did not execute them either. Instead, he kept them in the death row for observation for a period of time.

"Natural Energy, Cursed Seal, so that's how it is. Orochimaru, you are truly a genius of extraordinary talent. Your way of using this Cursed Seal is too superficial. This kind of Ninjutsu that seizes the very essence of heaven and earth is not meant for you to use..."

As the experiment ended, Naraku wore a thoughtful expression.

Having lived two lives, Naraku's views and methods of using Ninjutsu will always differ from those of the Shinobi World.

In Naraku's memories of his past life, Natural Energy was the power possessed by true immortals.

Chakra is created by fusing 50% of one's physical energy and 50% of one's spiritual energy, while Senjutsu Chakra is created by fusing 1/3 each of physical energy, spiritual energy, and Natural Energy.

From Naraku's perspective, it's correct that someone who masters Natural Energy can be called a sage.

However, those who can control Natural Energy are extremely rare in the Shinobi World; there are very few, and even including the Three Sacred Lands, they are only a handful.

If being able to absorb Natural Energy means having spiritual roots, then most people don't possess spiritual roots. Those who do have spiritual roots and can absorb Natural Energy are extremely rare, one in ten thousand.

Orochimaru's research on the Cursed Seal allows people to master Natural Energy on a large scale. Although it has flaws compared to the Three Sacred Lands, and there are unexpected issues with the Cursed Seal Level 2, it is like giving a person an opportunity. How far they ultimately reach depends on their individual destiny.

Naraku's insights and long-term investment in and focus on Natural Energy have finally paid off.

If Naraku can master Natural Energy, then he has a chance to become a true immortal!

"The Three Sacred Lands —the Snake, the Frog, and the Katsuyu —once I master the Natural Energy, I'll visit your sacred lands to see what natural treasures they hold."

Naraku's only dissatisfaction with the Cursed Seal was that mutated state, which allowed him to grow extra limbs or organs.

Orochimaru used two types of seals to distinguish between the Heaven and Earth Cursed Seal and ordinary Cursed Seal.

Ordinary Cursed Seal have lower requirements for the recipient, like the Sound Four. As long as the mutated limbs do not affect the recipient when the Cursed Seal Level 2, then even Jirobo of the Sound Ninja in his Jirobo Cursed Seal Level 2 state still has ten times the original power.

The survival rate of the Heaven and Earth Cursed Seal is relatively low, or rather, generally low. The Heaven and Earth Cursed Seal differs from ordinary Cursed Seal in that it releases more of the human body's potential and allows for the artificial intervention of growing organs or limbs, such as Orochimaru giving Sasuke wings and Kimimaro a tail.

Implanting the Heaven and Earth Cursed Seal is highly dangerous and can easily lead to the death of the recipient. However, as long as the recipient has potential and a strong will, accidents are generally unlikely to occur. The Heaven and Earth Cursed Seal only requires certain conditions from the recipient.

Otherwise, Orochimaru wouldn't have injected highly dangerous and lethal power into such excellent vessels as Kimimaro or Sasuke.

"Study the Heaven and Heaven and Earth Cursed Seal to see the specific differences between it and ordinary Cursed Seal. If it represents the speed of absorbing Natural Energy, then we need to consider the specific circumstances and inject it into ourselves..."
