In short, it must be a very valuable thing.

Close your eyes and slowly input your own chakra into it.

It can be clearly felt that there is a huge seal on the scroll. If you want to open this seal, you need to control chakra and explore the maze-like seal key stone until you find the exit. It not only requires extremely high control of chakra

strength, and a certain amount of luck.

In addition to medical ninjutsu and her strange power fist, Tsunade is also very accomplished in sealing techniques. Otherwise, she would not be able to develop Yin Seal, a secret technique involving sealing techniques such as Baihao no Jutsu.

In any case, her grandmother was Uzumaki Mito, who also came from the Uzumaki clan, and she must have taught him a lot of sealing techniques since he was a child.

After trying it several times, Shiren found that it really didn't work.

"Is my chakra control still too weak? I can't use the second-generation hard vortex water blade. Is it because my chakra control is too weak?"

Carefully put the scroll back into your ninja bag.

It may take a long time to open this scroll.

Clap your hands.

"Little Tsundere, let that soul out."

Erwei's eyes flashed, its mouth opened slightly, and an almost invisible soul spit out from its mouth.

The chakra on Toneri's body fluctuated slightly, and the second tail appeared on the surface. His eyes also flashed slightly, turning into one blue and one yellow.

But Taki-nin's soul, which was originally invisible and intangible, was now completely presented in front of him, like a substance.

The dull and dazed look on his face shows that his soul strength is average.

In the world of Naruto, most people's souls may maintain a certain level of intelligence when they just die, but as time goes by, they will slowly start to become a little dull.

Especially those whose soul strength is not strong enough, or those who have average or no Yin attribute chakra, their soul strength will generally be relatively weak.

This is not the first soul that Shiren has studied, and it certainly won't be the last.

He picked up a special container and a special knife from the experimental table.

This knife was made by extracting some special ingredients from Xiaolan's fallen nails. Its hardness may not be as good as ordinary knives, but it can touch the soul.

Gently peel off a small amount from the soul of Taki Ninja and put it into a special test tube that can store the soul.

"Little Blue!" Sheren shouted, and a blue and white cat jumped out from the corner, looking sleepy.

"It's yours."

Hearing this, Xiaolan's little nose twitched slightly, and her sleepy eyes immediately lit up, just like Erwei, she sucked this soul into her stomach in one gulp.

"Meow——" He patted his belly with satisfaction.

Ever since he learned that Xiaolan could freely absorb souls like Erwei, and could also increase his own strength by absorbing souls, the "leftovers" left over from Toneri's experiments would become its meal.

Except for Kato Dan's soul, which has been sleeping in its body, the rest of the souls are basically absorbed directly as long as they are inhaled by it.

With Erwei, a being who had eaten countless souls in the past, Toneri didn't have to worry about whether Xiao Lan's devouring so many souls would have a big impact on his body.

Seeing Xiaolan eating the soul with satisfaction and showing an expression of enjoyment, Toneri smiled and touched its head.

Xiaolan seemed to like Sanren to touch its head very much, and even took the initiative to rub it gently on his hand.

Will it make Toner feel uneasy or guilty about devouring other people's souls?

In this world of cannibalism, as a ninja, killing is just a common occurrence. Whether it is a ninja or a civilian, as long as it is required by the mission, he will not show mercy.

In other words, ninety-nine percent of ninjas will not show mercy.

So...feel guilty for blaspheming your soul?

Don't be kidding, countless ninjas have died at his hands, so what's there to feel guilty about?

Ruined their path to the afterlife?

Who knows if there is any so-called path to the afterlife.

Since reincarnation in the dirty earth can summon the souls of the dead from the underworld, there are actually many people who have been dead for decades. These people can be summoned, which means that they have not been reincarnated. So have they ever been reincarnated? I'm afraid this is

He is a fan of this world.

In this case, it is better to deal with other people's souls together, so as not to be summoned by the reincarnation of the dirty earth in the future, and come to seek revenge, and it will be over.

"Xiaolan, you go back first and tell Lingxiang to let her get ready. I will find an opportunity to bring her back to Konoha and let her dye her hair and other things. For the time being, all the characteristics of the Uzumaki clan will be covered up.

"Sheren said to Xiaolan.

"Okay, meow——"

Bang!

After that, Xiaolan lifted the psychic technique and returned to Lingxiang.

Immediately afterwards, Toneri came to the experimental table with a handful of souls in his hand.

He began to operate various instruments with ease and combined with his own chakra.

It didn't take long for that handful of souls to turn into a dark, gas-like, liquid-like thing in his palm.

It can be clearly felt that this dark mist-like thing appears, and the surrounding air becomes a little cold, as if someone has placed a huge ice cube in the air.

"Sure enough, every time I see Yin-type chakra, I will unconsciously feel a creepy feeling."

He looked at the ball of Yin-type chakra in his hand and murmured.

In the ninja world, in addition to the five basic attributes of wind, fire, thunder, earth, and water, there are also two attributes that are not known to many people, namely Yin Escape and Yang Escape.

For example, some families who use secret techniques involve Yin-Yang escape. For example, the shadow secret technique of the Nara clan and the heart-turning technique of the Yamanaka clan are methods of utilizing Yin escape, while the Akimichi clan's

The art of doubling involves Yang Escape within Yin Yang Escape.

But in fact, many people in these families may not know that the secret techniques they use actually involve Yin-Yang Escape, and they just think it is the family's secret technique. Only those who are really high-ranking in the family may know certain principles.

.

Also, illusion among the three ninja arts is actually a way of using Yin Escape. Therefore, some people have no talent in illusion, which means they have no talent in Yin Escape.

As for Yin Yang Dun, the most representative ones are the Uchiha clan and the Senju clan.

Whether it is the Uchiha clan or the Senju clan, their origins are from the Sage of Six Paths.

The Uchiha clan inherited the Six Paths Sage's Sharingan, that is, they inherited his Yin Escape.

The Senju clan of Mori inherited the Immortal body of the Immortal of Six Paths, which is the part of the Immortal of Six Paths that represents Yang Escape.

Therefore, after the Uchiha clan's Sharingan awakens to a certain level, the Sharingan can not only greatly increase itself, but can also possess pupil techniques to enhance their abilities in illusions. This is also because

The existence and growth of Yin Escape.

Unlike the Uchiha clan's Sharingan, which has a clear promotion method, it is very difficult for the Senju clan to awaken the immortal human body. So far, only Senju Hashirama has awakened the immortal human body and can use Yang Escape.

.

Yin Escape and Yang Escape restrain each other. In the process of fighting, who is stronger depends on whose Escape Technique is stronger, who has more quantity, and whose quality is better.

Although the Uchiha clan has a clear way to advance to the Yin escape, it is very difficult to reach the peak and reach the extreme.

The Yang Dun of the Thousand Hands Clan is even more difficult to awaken, but once awakened, its destructive power and vitality will be terrifying.
