Naruto: The Progenitor of Demons Starting from Kirigakure

First, there is the secret medicine, Hero's Water.

As an immortal being, Hero's Water is a way for Jieluo to harmlessly unleash a large amount of human chakra. What he needs to do is to study what kind of trigger Hero's Water stimulates which part of the human body, thereby causing the human body to unleash a large amount of chakra.

It is the same in nature as the Eight Gates Formation.

Jieluo wanted to master this method, which allowed him to stimulate and develop his body's potential autonomously without the need for the Hero's Water.

Therefore, a research team needs to be established, which requires seizing certain rights. Jie Luo doesn't have the time to do research, study, earn money, and search the entire ninja world for experimental orphans at the same time. Orochimaru is too idle.

Thinking of Orochimaru inevitably brings to mind Shingetsu, the spy planted in Konoha.

A small snake appeared in the psychic medium's presence. Jieluo then took out a scroll, wrote down instructions, and ended the psychic session.

So many days have passed; even a useless person should have infiltrated Konoha by now.

Next, Shen Yue needs to conduct extensive preliminary reconnaissance of Konoha. As for whether Shen Yue will be exposed, Jie Luo doesn't care. Jie Luo will continue to send spies to the five great villages. If they survive, they'll be considered capable.

This brings us to the second method of increasing chakra: Tobirama Senju conducted extensive human experiments and developed a technique that uses negative emotions to convert chakra.

Zero-tail manufacturing technology.

This research was likely developed by Tobirama Senju based on his research on the Sharingan of the Uchiha clan.

The Uchiha's eyes are naturally capable of converting their negative emotions into special chakra. Each time they awaken their eyes and advance in their level, their chakra reserves increase dramatically. Sanba's Uchiha is a Jonin, and his chakra reserves are among the largest of all Jonin.

These two chakra conversion methods are essentially ways in which life force or spiritual energy is converted into chakra separately.

It's unknown whether Tobirama actually began this research; it's highly likely that Hashirama stopped it halfway through and sealed it away, as Hashirama, who knew his younger brother well, was keeping a close eye on Tobirama.

Without one, Jieluo can only wait, or try to build his own research team to develop it. However, without a key figure to lead the development, the progress will be far from optimistic.

The intelligent people in the ninja world, those with the talent to develop ninjutsu, and the second-generation leaders of each village are all such figures.

Shamon of Sunagakure, Gengetsu of Kirigakure, Mu of Iwagakure, and A, the Second Raikage of Kumogakure.

If they had lived longer, Jieluo couldn't even imagine how ninjutsu in the ninja world would have developed. It's truly a pity that such talents perished in the Ninja War.

The development of techniques in each village is based on the legacy left by the Second Mizukage, except for Kirigakure. Due to Kirigakure's secrecy policy, the Second Mizukage's techniques simply vanished without a trace, leaving no one to inherit them. Secondly, it is based on friendly exchanges between the five major villages. Techniques such as Shadow Clone Jutsu were deciphered from the corpses of ninjas.

"Shadow clones..." Speaking of shadow clones, Jieluo was full of resentment. Fortunately, Jieluo still had a monkey's head in his hand. When he saw the shadow clone being used, Jieluo decided to keep the head.

The third way to increase chakra is currently what Jira is mainly studying and researching: Earth Grudge.

I couldn't help but think of Kakuzu. How was his study going? Was he searching for a suitable heart throughout the entire ninja world? Judging from what I'd learned over the time I'd been studying, it couldn't be that fast. At this moment, Kakuzu was still modifying his body according to the requirements of the forbidden technique.

As for demonic power, Jieluo really couldn't do anything about it. Unlike chakra, it wasn't as convenient or easy to use. Perhaps due to his demonic talent, Jieluo couldn't even unleash a wave of demonic power. He could only instinctively condense his demonic power into strands of hair. The enhancements to his body were merely byproducts of his demonic power. He also exhibited a certain degree of self-healing ability, but he couldn't enhance or amplify his body like he could with chakra.

Jieluo didn't even have anyone to imitate or learn from.

How do other demons do it? Naraku, for example, grows by absorbing and devouring the demonic power and abilities of other demons. He can even spit out abilities he doesn't like. Inu no Taisho does the same thing, using his forged sword to devour the talents and abilities of various demons.

If there were demons in the ninja world, they could do the same, but Yura could only develop based on hair.

In general, Jieluo has only two innate abilities: one is the application of demonic power, which manifests in her hair, and the other is the application of her soul, which manifests in her will-o'-the-wisps and immortality.

There hasn't been much progress on a spiritual level, but I've managed to barely get started in using emotions.

It can materialize emotions and spirits, mimicking various real physical phenomena. It's not just limited to becoming a blade; it can also become a hammer to impact mental and emotional states. There are many fancy tricks it can do.

For example, the Heart Sword.

As they flew, Lucy slowed down, turned around, and flew backward, saying, "Great monster, a group of pirates is coming!"

Flying low will cause this, as you will encounter all sorts of road conditions.

"Want to fly higher?" Lucy asked.

Jieluo slowly shook his head and said, "No need, just fly there normally."

"Understood." Lucy turned around and dragged Jieluo forward. Soon, a large ship appeared on the sea at the edge of their vision. As the two approached, the sailors on the watchtower spotted Jieluo. As the whistle sounded, samurai and sailors began to gather on the deck.

"Wow, look what prey we've spotted! A little girl flying!"

A burst of joyful laughter erupted, and the group waved their weapons noisily.

At this moment, a clearly dominant male figure shouted arrogantly, "Move closer!"

With sails billowing and the ship's brick rudder in hand, it sailed straight toward Jieluo.

Looking at the old, large ship approaching, Lucy's eyes showed a hint of pity. "I wanted to save you before."

The two sides quickly approached each other, and as they drew closer, the group on the deck shouted for Lucy to stop.

Lucy ignored them, nimbly turning to make way for the ships in her path.

Seeing this, realizing that Lucy was trying to escape, the group began to attack. The samurai with swords shouted and fired arrows, which were sparsely fired towards the direction of Yura. Not only were the arrows poorly aimed, but their range was also short, and they all fell into the sea.

While firing, he didn't forget to threaten, yelling at Lucy to stop.

Lucy flew with her head down, passing by the side of the ship. The next second, the shouts seemed to be paused eerily, and then fell silent. Lucy was startled and turned to look at Jieluo, only to see Jieluo smiling faintly, her scarlet eyes looking in the direction of the ship.

With a thud, something fell into the sea.

Lucy turned her head and saw a group of people on the deck, their faces turning blue and purple, clutching their necks in agony. One by one, they began to fall to the ground, many of them falling into the sea. There were no screams, only intense, painful struggles and rolling around, before they died quietly one by one before her eyes.
