Night.

The moonlight was like a waterfall, sprinkled on the earth.

In the clan mansion of the Kurama clan, many clansmen gathered together to celebrate the improvement of the health of Kurama Yakumo, the only daughter of the clan.

This news is really exciting news for the Kurama clan, who have weakened to the point of not being able to look, and even the patriarch is only worthy of reaching the level of ordinary upper ninja.

The Kurama clan needs a strong man too much!

Otherwise, this wealthy family with the blood inheritance limit and once stood shoulder to neck with the Uchiha will really become a laughing stock among the wealthy families.

On a big tree outside the Zong's mansion, two shadows stood side by side.

Looking at the brightly lit Pomma Clan's mansion not far away, one of the young shadows was a little worried: "Senior, I heard that the Kurama clan is a wealthy family with a blood inheritance limit, we are so close to watch, will they find out?" ”

The elder Shadow smiled: "Don't worry, the Kurama clan has been weakened for a long time, and even their current patriarch is also the Shinobi promoted by Hokage-sama to make an exception based on the past merits of the Kurama clan, so even if we sneak into the house, they may not be able to find out." ”

】

"I didn't expect that the former wealthy family would weaken to such a degree!" After the young shadow sighed, he then asked, "Senior, how long will the surveillance in this situation last?" ”

The elder Shadow replied, "It's hard to say, but I heard that this time it was Tsunade-sama himself, let's keep an eye out for all the suspicious people approaching Kurama Yakumo, in my experience, such a mission usually lasts a few weeks, or more." ”

And just as the two shadows were chatting in a low voice, behind the two of them, a spirit was quietly watching them.

Mother Yong undoubtedly said that this spirit body was 'Yin Du'.

Her gaze staring at the two dark parts was extremely cold, if it weren't for the fact that she was still worried about Shinji and Yakumo, I was afraid that she would have already started killing at this moment.

After a final hateful glance at the two shadows who were spying on Yakumo, she flickered and disappeared in place.

A moment later.

She floated into a wooded part of the village, came to the figure in a red cloud suit and a mask, and saluted respectfully.

Shinji nodded, "How's it going?" ”

Yin Du said, "As you expected, the village really arranged a dark department to monitor Yakumo's every move outside the mansion. And I overheard their conversations, and the one who assigned them monitoring tasks was Tsunade! ”

"I didn't expect her to see some clues..."

Shinji wasn't surprised.

During the day, he had a feeling that Tsunade must have discovered something, so he instructed 'Yin Du', a spirit that can travel freely, to keep an eye on the surroundings of the Kurama clan's mansion.

'Yin Du's face rose sharply: "I'm going to kill her!" ”

Shinji glanced at 'Yin Du' and chuckled, "You're in such a hurry to send him to death?" ”

'Yin Du' was a little puzzled: "What do you mean?" I'm in a spirit state, and she can't even find me! ”

"Spirits are not invincible." After a pause, Shinji said, "Have you ever heard of the 'Spiritualization Technique'?" Tsunade's former boyfriend is a strong man who is good at 'spiritualization', and he can break away from his body in the form of a spirit and kill the enemy, but he still dies on the battlefield in the end! ”

'Yin Du' face sank when he heard this.

Shinji said: "There are more than a dozen ways to restrain spirits that I can think of, do you think that as one of the three ninjas of Konoha Tsunade, she won't?" ”

"Hold... I'm sorry! ”

'Yin Du' hurriedly bowed his head and apologized, and the arrogance that he had just spied into the shadows and was not discovered disappeared at once.

Shinji waved his hand, "Alright, let's start testing!" ”

He didn't just want to confirm whether Tsunade had sent someone to spy on Yakumo.

He also has an important purpose, which is to test 'Yin Du'.

After listening to Shinji's explanation, 'Yin Du' nodded hurriedly, and then galloped away in one direction.

Because she was a light spirit, she flew extremely fast, so in the blink of an eye, she had already flown out of the village and disappeared from Shinji's field of vision.

Looking back at Konoha Village, which was getting farther and farther away, getting smaller and smaller, the 'Yin Du' in flight suddenly had a feeling of a vast sea and sky.

At this moment, she was extremely happy!

But after flying for a while, she suddenly felt dizzy.

At first, she didn't pay much attention to it, but as she got farther and farther away from the village, she found that her spirit was getting weaker and weaker.

"Why is this happening!?"

In her rapid weakness, she stopped, and sped away in the direction of the village without looking back.

As she began to approach the village, her weakness gradually disappeared, and it was only then that she realized that the cause of her weakness was the distance from the village.

No, to be precise, it should be far away from Yakumo, who was in the village.

Returning to Shinji, 'Yin Du', who still has a lot of luck in his heart, reports his findings to Shinji.

Shinji calmly recorded: "After ten kilometers away from the main body, the spirit body began to weaken, and after twenty kilometers away from the main body, the weakening state increased rapidly. It is speculated that the maximum distance of the spirit's activity is about 25 to 30 kilometers within the radius of the main body. ”

'Yin Du' was shocked, she just reported the phenomenon of weakness in her body, and did not mention the specific distance value.

Unexpectedly, Shinji not only seems to have discovered it a long time ago, but even the distance from which the weakening appears is clear.

For a moment, she felt as if everything about herself was under Shinji's control.

Shinji didn't care about 'Yin Du''s careful thoughts, and still recorded the data.

He had long expected that 'Yin Du' would not be able to stay away from Yakumo, after all, only a chakra that reached the level of a shrine maiden that was close to the 'six realms' could split into an independent monster 'Dragon' comparable to a tailed beast.

The rest of the ninjas, no matter how amazing their talent is, the chakra level is there, and it is difficult for the monsters that are split out to exist independently.

However, as the experiment deepened, he found that his new red eyes really seemed to have the ability to strengthen the spirit body.

"If I transplant these red eyes to Yakumo, and add Yakumo's own high-quality Yin Chakra, it should be able to make Yakumo obtain a Yin Chakra that is close to the level of the Kaleidoscope Writing Wheel Eye..."

"When the time comes, I'll transplant white absolute cells to Yakumo to make up for the congenital deficiencies in her body..."

"At that time, her strength should be greatly improved, and perhaps, the power of 'Yin Du' can also be further enhanced, and she will become a monster that can truly exist independently..."

Thinking about it, Shinji's thoughts began to diverge...
