Red sand dust

In Konoha Village, a light-tight underground laboratory is surrounded by dense protective barriers. Not to mention chakra perception, even time and space ninjutsu cannot easily penetrate it.

The department responsible for the operation here does not even have a formal name, but many functional departments and special ninja units in Konoha Village established their prototypes here, then grew and transformed, and finally became independent.

Except for the knowledge of a few high-level members of Konoha Village, this department is generally under the jurisdiction of the ANBU, but is directly responsible for the Hokage. It was originally organized by the current Hokage Fifth Generation Tsunade to prepare a medical force during the Ninja World War.

Over the years, countless dangerous and important experiments have been carried out here, and the results have also benefited the village a lot.

This time, it's no exception.

The Ring of the Jade Girl, which many research teams were unable to do anything about, was finally transported here for final identification.

After several days and nights of testing, the experienced research ninjas managed to find some clues.

After receiving the news, Tsunade, who came here to listen to the report, frowned and read the preliminary report several times.

"Are you...sure you're not mistaken?"

The material looks like gems or metal, but is actually not any known material.

Not only that, the Ring of the Jade Girl is almost unresponsive to some chakras. It is an almost "magic-proof" ninja tool.

If it were just like this, although it was magical, it was not worthy of too much attention. However, when the researchers carefully scraped off a layer of debris from the Ring of the Jade Girl, they unexpectedly discovered that there were resonance fluctuations between the same materials.

In other words, the appearance of the ring is not important. In essence, it is an ultra-long-distance communicator and power transmission device.

"Tsunade-sama, at first we didn't believe that such a simple structure could have such a magical function. After testing it several times, we had to admit that it was true..."

The researcher, who was wearing light blue protective clothing, answered with certainty,

"The key to realizing this function lies in the special properties of its materials. With our methods, it is no longer possible to conduct further research..."

Tsunade nodded with a somewhat ugly expression:

"Is it effective to exclude chakra and ninjutsu..."

Such an ability, if it can be used freely, can almost form a crushing advantage over ordinary ninjas.

But the enemy actually uses this kind of thing to make it into a prop and liaison device that symbolizes identity. This is too extravagant.

A rebel ninja organization actually had such a method, which made Tsunade unconsciously increase the threat of the "Akatsuki" organization by a large margin.

No wonder the "Akatsuki" organization can know that the Ring of the Jade Girl is in the Sand Hidden Village. The enemy has the means to detect the location. Even if it is not accurate, it is enough to have a rough idea.

"Strengthen protection! Research will continue. If you find anything, please notify me in time..."

Tsunade ordered sternly, and at the same time, she really felt that she had taken over a hot potato from Sunagakure Village.

Although our side has arranged a barrier in time to hide it, the "Akatsuki" organization must have noticed it.

Although I don't want to conflict with those powerful rebels at this time, the development of things is beyond our control.

After returning to the Hokage's house, Tsunade put aside a lot of tedious chores and went to the secret library to check.

After a short while, Tsunade, who searched countless ancient documents, finally found some valuable clues.

"The legend of Yin Yang Escape...!"

She reached out and pressed her temples and rubbed her eyes, which slightly relieved the pressure on her eyes. Tsunade couldn't help but feel tired.

"Ancient legends are beginning to appear one by one, and the ninja world... is getting more and more troubled!"

Not all the old guys from the Warring States Period are dead yet, some who are unwilling to be left alone have also begun to make trouble, and the younger generations are also more powerful than the last.

The era of Uchiha Madara and Senju Hashirama passed, and the Uchiha mirror was regarded as the hope of the whole family. As a result, in recent years, when the number of Mangekyo Sharingan increased, the Uchiha family was actually exterminated.

The world is changing faster and faster, and it is getting weirder and weirder.

Just when Tsunade was thinking about something, there was a knock on the door, and Shizune opened the door and walked in.

The Godaime disappeared for a long time, and there were many things waiting to be decided. Shizune had to take on more responsibilities, and finally found Tsunade.

"This...has made the data room such a mess again!"

Looking at the scrolls and books scattered all over the floor, Shizune's delicate face couldn't help but reveal a hint of anger. This was not something that he had managed to sort out not long ago with Shenyue Izumo and Gang Zitie.

Without waiting for the conscientious assistant to complain, Tsunade took the lead and said:

"You're here just in time. Go and call the two consultants Mito Monohan and Koharu Koharu. I'll be waiting for them in the office... By the way, I'll call Elder Danzo Shimura to come too!"

Decades ago, when Tsunade was still young, some things were not very clear. The advisors and elders who were still alive might still remember some more important past events, and some top secrets that were passed down by word of mouth would not be recorded in documents at all.

…

At the same time, on a hidden uninhabited island in the vast sea in the south, in an underground base hidden by rocks, Orochimaru watched with interest Uchiha Sasuke standing on the side holding a sword, wiping the oozing fluid from a small wound on his forehead. Bloodstains.

The Uchiha orphan was not in good condition. He looked quite embarrassed and consumed a lot of physical strength and chakra, but he could still maintain a good mental momentum.

"Did you also lose today? Sure enough..."

Orochimaru habitually stuck out his tongue and licked the corner of his mouth, laughing softly.

Orochimaru was very satisfied with Uchiha Sasuke's growth rate.

Although he is much weaker than Uchiha Itachi of the same age, that is just a difference in personal experience.

Uchiha Sasuke's talent is no worse than that of his brother. Catching up with the tail end of the Third Ninja War, Uchiha Itachi, who went to the battlefield at a young age and survived the test of life and death, it is natural for him to grow up so fast.

The potential of the two brothers is actually about the same. It doesn't matter if they grow slower. As long as they can obtain the power of Sharingan, it doesn't matter to Orochimaru sooner or later.

However, Uchiha Sasuke was quite dissatisfied with losing to a boy about the same age as Uchiha Itachi over and over again, especially when he heard that the ridiculously strong blond gangster-looking guy was actually Uchiha Itachi's subordinate. The defeated general couldn't bear the anxiety in his heart.

"Continue tomorrow..."

"It's good to be ambitious, but you should also be relaxed..."

Orochimaru shook his head slightly,

"It's not surprising that you can't beat the Tsuchikage Sandaime's proud disciple now. After all, he is three or four years older than you..."
