Naruto: Can't learn ninjutsu? I'll just practice immortality!

"The best choice is of course to learn Sage Mode directly."

"But if the talent is not enough, most ninjas will never be able to learn Sage Mode in their lifetime."

"Even with Jiraiya's talent, he needs the assistance of two toads, Fukasaku and Shima, to enter Sage Mode."

"Even if I am more skilled in Sage Mode in human form than the three holy places, if I want to really learn it, it depends on the talent of the ninja."

Asakawa Naoki thought carefully. The Curse Seal is not as talent-oriented as the Sage Mode. As long as they can bear the cost, the Four Oto Ninjas can use the Curse Seal.

But to develop the Curse Seal, some experimental subjects are needed.

Orochimaru once captured hundreds of experimental subjects to develop the Curse Seal, but only the Four Oto Ninjas succeeded in the end. The rest either died or turned into insane monsters.

Although Asakawa Naoki traveled to this cruel ninja world, he could not do experiments on living people like Orochimaru did.

The reason is that his soul and heart are from the Celestial Empire after all. If he uses living people for experiments, what is the difference between him and those invaders?

"By the way, it seems that there are two White Zetsu clones in the cell." Asakawa Naoki suddenly remembered something.

A few months ago, he also captured two White Zetsu clones.

Since White Zetsu clones can be used as materials for Impure World Reincarnation, they should also be used as experimental subjects for developing curse seals.

Perhaps each ninja village has experiments similar to Konoha that use living people to fuse Hashirama's cells. Even if the Hidden Rain Village joins, it's okay, but Asakawa Naoki can't get over the hurdle in his heart.

But if he uses White Zetsu clones, Asakawa Naoki doesn't feel much guilt.

"Yuchuan, take me to see the place where White Zetsu is kept." Asakawa Naoki said.

"Lord Akiba, this..." Yuchuan hesitated, as if he had something to hide.

"Are those two White Zetsu dead?" Asakawa Naoki asked in confusion.

"He's not dead, but, forget it, go and see for yourself." Yuchuan said slowly, even through the mask, Asakawa Naoki seemed to see through the helplessness on his face.

Going deep into the prison, after stepping into a certain area, Asakawa Naoki felt as if he had walked into a dry toilet, and the stench kept rushing into his nostrils.

"What's going on?" Asakawa Naoki frowned, his incarnation's sense of smell was quite sharp, and he could smell the smell clearly.

"Report to the Lord, you require that the survival of these two prisoners must be guaranteed," Yuchuan explained helplessly:

"These two prisoners have strong vitality and can survive without food and energy."

"But one of the prisoners is desperate, and the guarding ninja must give him feces, otherwise he will commit suicide out of boredom."

"Even if he is sealed, he said he has a way to commit suicide."

"The guards have no choice but to do as he said, give him feces, and then use the sealing barrier to isolate the surrounding smell."

"..."

Asakawa Naoki looked at the White Zetsu in the cell who was studying feces as if no one was around, and then looked at the other White Zetsu lying flat on his back to sleep.

In Naruto, White Zetsu is a peculiar creature that can survive without food and energy, so some White Zetsu clones have a strong curiosity about normal human behaviors such as eating, drinking, defecating and urinating.

Comparing the two White Zetsu in the cage, Asakawa Naoki suddenly came up with a plan.

"Vajra Lock!"

Behind Naoki Asakawa, two golden chakra chains quickly penetrated into the cell, tied up the two White Zetsu and pulled them out of the cell.

After staying in the cell for several months, they were suddenly caught out, and both White Zetsu clones panicked for a moment.

However, Naoki Asakawa keenly discovered some differences. The White Zetsu clone lying flat was more relieved, while the White Zetsu clone studying poop was more nervous and afraid of death.

Thinking of this, Naoki Asakawa had more confidence in his idea.

"Water Style·Water Array Wall!"

Naoki Asakawa clapped his hands, and a stream of water rushed up from under the two White Zetsu clones, washing away the filth on their bodies. The simple ninjutsu surprised Yuchuan next to him.

"I didn't expect that Akiba-sama could use a B-level ninjutsu like Water Array Wall at this age. You are worthy of being Akiba-sama!"

Yuchuan was proud of his strength far exceeding that of ordinary jonin, but even he couldn't use Water Array Wall without a seal. He didn't expect that Asakawa Naoki, who was younger than him, could do it.

Asakawa Naoki naturally didn't know that the no-mark ninjutsu he used casually made Yuchuan's awe of him increase again. He had already focused his attention on the two cleaned White Zetsu.

"What are you looking at? Kill them if you want." The lying White Zetsu said fearlessly, as if he was ready to accept his fate. The White Zetsu, who was only full of curiosity, didn't speak, as if he had also accepted his fate.Generally.

"Since you want to die, I will satisfy you."

Closed his eyes, when Asakawa Naoki opened his eyes again, the feeling he gave to Yuchuan was completely different.

If the previous Asakawa Naoki and the Salamander Hanzo's momentum were similar, then the Asakawa Naoki in the perfect sage mode was far more powerful than Hanzo.

Standing next to Asakawa Naoki, Yuchuan seemed to be facing a monster.

Fortunately, Asakawa Naoki did not target Yuchuan, and his powerful momentum directly pressed towards the two White Zetsu, making them seem to smell the breath of death.

"Go!"

Asakawa Naoki did not touch the White Zetsu, but directly injected the condensed senjutsu chakra into the fearless White Zetsu through the chakra chain blocked by the diamond.

He would not be as disgusting as Orochimaru and the three goddesses of Ryuchidong, who had to inject senjutsu chakra by biting people, which was too unhygienic.

"What did you do to me?"

The White Zetsu who was injected with senjutsu chakra felt as if there was a powerful force in his body, as if he was going to burst himself.

"It hurts so much!"

"Ah!"

Under the stimulation of the fairy chakra, White Zetsu felt as if something was about to break out of his body.

"No!"

With screams, branches grew out of the body of White Zetsu injected with fairy chakra, and finally the whole White Zetsu was pierced by the trunk and turned into a small tree.

"This..."

The process of White Zetsu turning into a small tree made Yuchuan beside him stunned. The pain of the tree growing from the body and bursting the body was a bit numb even for him as a ninja of the Rain Hidden Village.

Not to mention the other White Zetsu who was also tied up by the chakra chain, watching his companion die in such pain, as if it would be his turn the next moment.

Unlike the dead White Zetsu who lay flat and was not afraid of death, the living White Zetsu had a strong curiosity about poop. He didn't want to die yet, and he also wanted to experience the eating, drinking, and defecation of humans!

But at this time, Asakawa Naoki had already stared at him and sighed:

"It's a pity that the experiment failed."
