Hero Water

Konoha

Konoha Prison

In the warden's office, Naraku sat imposingly in the warden's seat, with Uchiha Riki standing beside him as a bodyguard.

In the center of the office stood a tall, pale-faced prisoner.

The prisoners in Naraku's court whispered:

"Kounai Kosuke, your brother sacrificed himself in the Battle of Iwagakure, but that is no excuse for you to slaughter the people of the Land of Earth and the Iwagakure Ninja. Konoha and Iwagakure have restored peace."

"Then what was the point of my brother's sacrifice! Iwagakure can slaughter the citizens of the Land of Fire, why can't Konoha retaliate against the Land of Earth?!"

The prisoner was not convinced and retorted loudly.

"How dare you!"

Seeing the prisoner's disrespect towards Naraku, Uchiha Riki, who was standing nearby, couldn't help but shout.

Naraku raised his hand to stop Uchiha Riki, and sighed:

"You attacked those Iwagakure Ninja for their Ninjutsu, didn't you, Kounai Kosuke? You're a Special Jonin skilled in soul Ninjutsu and soul probing, and you've been listed as a serious criminal by the Third Hokage Sarutobi Hiruzen, for a twenty-year prison sentence. Even I can't reduce your punishment."

"Fourth Hokage, you are the one who advocates war, and we all support you! Why, why not retaliate against Iwagakure? Even if I die, I would be willing to die to avenge you!"

Prisoner Kounai Kosuke sabotaged the peace talks between Konoha Iwagakure during the Third Hokage's administration, and was thrown into Konoha Prison by the Third Hokage and sentenced to twenty years in prison.

"Kounai Kosuke, you are one of my supporters. You desire great power, and I can help you. However, this power is still under research and carries the risk of death."

If you can endure it, it will be considered as helping me research Ninjutsu. I will secretly release you, but from now on you will only be able to live as missing-nin. Are you willing?

Naraku collected the Hero Water and used it to alter Jugo 'Hero Water bodily fluids, the raw material for the Cursed Seal.

Naraku's Cursed Seal experiments, including the Heaven and Earth Cursed Seal and ordinary Cursed Seal, have all been conducted, and the data is already clear.

In practice, the two types of Cursed Seal are similar. Those with strong physical endurance, high talent, and strong will have a higher success rate in receiving the spell. Otherwise, the survival rate is probably similar to that in experimental data.

Ordinary Cursed Seal are less dangerous at the beginning and can also reach the Cursed Seal Level 2, absorbing Natural Energy. However, when ordinary Cursed Seal reach the Cursed Seal Level 2, there are some uncontrollable mutation factors, and they are not very perfect.

Naraku already had a clear idea of the use of the Cursed Seal: the Heaven and Earth Cursed Seal has a high initial fatality rate, but no risk in the later stages.

Ordinary Cursed Seal have a high survival rate upon implantation, but the physical mutations that occur when one first reaches the Cursed Seal Level 2 state pose considerable risks.

"I attacked Iwagakure for Ninjutsu. If it can increase my power and free me, then I'm willing to do it even if it means losing WeChat."

"Fourth generation lord, when I leave the village, there will only be one place I go to, and that is the Land of Earth."

Kounai Kosuke readily agreed to gain power and freedom, and explained his destination after leaving.

His purpose in going to the Land of Earth is self-evident; he wouldn't do anything else but cause destruction.

"That's up to you, just don't mention Konoha's name. Since you've made up your mind, then... let's go."

Naraku replied softly, a swirling wind appearing in his right palm, revealing a syringe filled with blue liquid.

The original Cursed Seal, made with Jugo's bodily fluids, was purple. Naraku, used Hero Water instead, and after successfully mixing it, the Cursed Seal liquid turned blue.

After Naraku's experiments and slight modifications, the Cursed Seal, when mixed with Hero Water, can achieve the same stability and potential as the Heaven and Heaven and Earth Cursed Seal Cursed Seal, even though the ordinary Cursed Seal has a slightly higher survival rate. This experiment aims to see what the Cursed Seal Level 2 made with Hero Water looks like.

Upon Kounai Kosuke walked up to Naraku without saying a word and extended his arm.

Naraku pushed Kounai Kosuke's arm aside and injected the syringe into his neck. Three Tomoe appeared on the back of his neck.

Naraku placed his left palm on Kounai Kosuke's neck, and held his right index and middle fingers together in front of his chest, fusing the soul threads and Cursed Seal into Kounai Kosuke's body.

"Ugh!"

After the Cursed Seal was implanted, Kounai Kosuke cried out in pain, covered the Cursed Seal on the back of his neck with both hands, and lost consciousness.

"Naraku, shall we take him to a guest room to rest?"

Uchiha Riki standing nearby, watched this scene. Having observed Naraku's Ninjutsu experiments many times, he already had some understanding of them.

"No need, just leave him here. You can go about your business."

Naraku up, carried Kounai Kosuke to the sofa, and echoed.

"Hi..."

Uchiha Riki answered softly and left the office.

Naraku, meanwhile, was observing Kounai Kosuke from his office.

The survival rate of a normal Cursed Seal is fifty percent, but if the recipient is strong enough, healthy enough, and has good Ninjutsu skills, the actual survival rate is higher than the data suggests.

About an hour later, Kounai Kosuke woke up, gritting his teeth, seemingly enduring pain.

How are you feeling?

After Naraku noticed, he asked softly.

Kounai Kosuke's Cursed Seal on his neck and spine rippled, black wave patterns covered half of his face, Chakra visibly increased.

"My Chakra has increased nearly fourfold! What incredible power!"

Kounai Kosuke clenched his fists. Although his face showed pain at the increase in Chakra, his eyes gleamed with excitement.

"Don't rely on this power for too long. It's a double-edged sword that will endlessly drain your body's strength. The upgrade isn't over yet, consume it."

Seeing that Kounai Kosuke was alright, Naraku took out a small jar, poured out a pill, and tossed it to Kounai Kosuke.

Kounai Kosuke caught the black pill and swallowed it in one gulp. Five seconds later, Kounai Kosuke clutched his neck, his eyes widening as if he were suffocating.

Naraku's palm rippled, transforming into a wooden barrel, and he Kounai Kosuke into it.

He created Shadow Clone, cast the Four Black Mist Formation and the Black Sealing Formation and Black Sealing Method Seal, and then continued to observe Kounai Kosuke's condition.

About two hours later, the barrel shook, Naraku up, tore off the talisman, and Kounai Kosuke's figure climbed out of the barrel.

"This is... a rich source of Natural Energy! Hero Water, Sacred Water, excellent!"

Naraku's crimson eyes observed Kounai Kosuke.

Kounai Kosuke, who had just completed the upgrade of his Cursed Seal, remained in the Cursed Seal Level 2. His entire skin had turned grayish-black due to the erosion caused by the Cursed Seal. After a while, his skin color returned to normal, but a rich amount of Natural Energy still existed within his body.

In the Cursed Seal Level 2, Kounai Kosuke did not undergo any abnormal changes or grow any strange organs or limbs. Moreover, Kounai Kosuke's skin color was normal, and he had abundant Natural Energy within his body.

Do you like this power?

Naraku looked at it like a work of art and asked softly.

"Incredible power, Fourth Hokage! With this, I have nothing to fear, even against the strongest ninjas from Iwagakure!"

Kounai Kosuke tensed up, clenching his fists as if he possessed boundless power.

"Alright, alright! Leave at midnight, at the Konoha East Gate. The prison will release you after 8 PM. You have four hours to move around, pack your things, and tell your family and friends what's happened. Don't miss the deadline."

Naraku said softly, preparing to release this Special Jonin who supported him. After all, he hadn't massacred the people of the Land of Fire, and in Naraku's eyes, this man's minor mistake had already been offset by the Cursed Seal experiment.

"Lord Fourth Generation, I will always remember your kindness!"

Kounai Kosuke is not a death row inmate, but a ninja who respects the Hokage. As he finished speaking, Kounai Kosuke's skin turned grayish-black, and then the grayish-black skin emitted a light like magma. The Cursed Seal gradually contracted and returned to the Cursed Seal behind his spine.

"Rest well in the office. Don't leave until after 8 o'clock. I'll have someone bring you food. Just wait patiently."

Naraku gently comforted him, then got up, waved, and left.
