The opening day has come to the end, and Kakashi did not take care of the Naruto, Karin, and Jugo all day.

After all, they need to experience these themselves, so Kakashi will not be their nanny.

Moreover, Kakashi is already Anbu Captain. Although there is not much business to do due to the special nature of Anbu, there are always some mission scheduling tasks.

"Shisui, Itachi, this time there is a mission that requires the three of us to go together. You two pack up now. We need to go outside the village."

Zhishui and Itachi did not ask much, and quickly packed up and prepared to set off.

A month later, in the southern part of the Land of Fire, Kakashi, Shisui, and Itachi are sitting under a big tree to rest.

"Silver, I didn't expect this mission to finish smoothly. It was completed all at once." Shisui said happily.

"This mission is not difficult. After all, the most important thing is to let Crow familiar with Anbu's work."

Hearing this, Itachi then said: "Thank you senpai."

"You're welcome, I believe that with your talent, this one time is enough for you."

Itachi nodded as he agreed.

"Well, it's getting late, let's rest here tonight, and we will go back tomorrow." Kakashi said.

Shisui and Itachi naturally have no problem with this.

After the three of them ate a little bit of food, they each found a tree and leaned on the tree to rest.

Of course, it is impossible to get into deep sleep. In the wilderness, only people like Naruto can sleep like a log.

Obviously, these three people are not someone like Naruto.

The night is silent and there is often a breeze blowing.

The weather in October is always a bit cold.

The dark clouds in the sky seem strange.

Kakashi, Shisui and Itachi opened their eyes suddenly, their scarlet Sharingan was revealed at the same time, and the seal on Kakashi's left eye was directly opened.

The three people were shocked as their own Sharingan actually working uncontrollably.

The three of them stood up at the same time, and they all saw surprise and doubt from the eyes of each other.

"What's going on here? Why did our Sharingan spun uncontrollably?" Shisui asked doubtfully.

Kakashi and Itachi are silent, as they also don't know what's going on.

At this time, the red light has faded from the Sharingan, and their eyes returned to the former state.

Only, the three of them did not think that this was an accident.

The three of them looked at each other and felt something is wrong. It looks like this place is not simple.

This barren mountain is just a small place where three people passed by, and there is nothing on the map. Is this place related to Sharingan?

They didn't know, but this may be the only explanation for this strange phenomenon.

Otherwise, the Sharingan's abnormalities from before cannot be explained at all.

"There is something strange. I think that it has something to do with this place. Now we have two choices. One is to uncover this problem, and the other is to leave this place immediately. What do you guys think?" Kakashi touched his chin and said his suggestion.

Shisui and and Itachi looked at each other, and both saw the intents in each other's eyes.

When Kakashi saw this, he knew that they want to uncover this problem.

"Then let's start to act. Blink, Crow, because the target is uncertain, we should split up and move in three directions. This mountain is not big, so half an hour should be enough for us. Then, whether or not we find anything, we will meet up here after half an hour and start planning. Is there a problem?"

"No!"

"Good, then go!"

Kakashi gave an order and the three of them dispersed.

All of them are shinobi with a certain level of strength. At this time, there is no need for them to act together, so it is more efficient for them to split up searching for clues.

Half an hour later, Kakashi stopped on a big tree.

"Weird, there is nothing here. Is it on Shisui or Itachi's direction?"

Kakashi's heart is secretly thought, and the eyes are full of thoughts.

"Forget it, I just need another way to find it."

Kakashi murmured, and then he made a peculiar hand seal on with his both hands.

"Kai!"

At this moment, the three silver-white tomoe behind Kakashi kept turning, and then a terrifying Natural Energy starts to fill Kakashi's body.

Near to Kakashi's eyes, red eyeshadows appeared instantly.

Sage Mode!

Under the Sage Mode, the whole barren mountain is in Kakashi's perception.

Kakashi soon discovered Shisui and Itachi's Chakra.

"Shisui and Itachi are both coming back, and it seems that they haven't found anything too."

"Hmm? This is!"

Kakashi's eyes widened suddenly as he feels a very powerful chakra reaction.

And it is very concealed!

In the middle of the mountain!

"This is not a human's chakra type, what is it?"

Kakashi frowned as he presses his right hand against his chin, and no one knows what he was thinking.

As he had discovered his target, the Natural Energy inside Kakashi's body starts to faded and returned into the silver-white tomoe Cursed Seal.

"Silver! Did you find anything over there? Neither Crow nor I found anything."

Shishui and Itachi also come back at this time, but they found nothing.

"Yes, you guys come with me."

Kakashi decided to go and take a look as he couldn't think of anything.

The incident this time obviously has something to do with the Sharingan, so Shisui and Itachi are naturally the best helpers he can get.

After hearing this, Shisui and Itachi followed Kakashi and move all the way and then they soon arrive at a lake.

"Silver, is this?" Shisui asked curiously.

"Under this lake, there is an underwater channel that is connecting to the inner side of the mountain. You can take a look with your Sharingan."

Hearing this, Shisui and Itachi didn't hesitate, and directly opened their Sharingan.

Sure enough, under Sharingan's view, there is a passage under the water.

It's not that Sharingan has the ability to saw through the water, but there is some strange chakra inside the underwater channel, and Sharingan is able to see it clearly.

"What is this place? Why is there a very strange feeling?" Shisui said.

"This place is very unusual. I don't recommend us to go down there." Itachi said calmly.

What Itachi made sense, this place was weird inside and out, and it may be dangerous for them to go there.

"Crow, don't say that, since it can be sensed by the Sharingan, it must be related to the Sharingan. Maybe there is a secret of the Sharingan. I think we should go in and take a look." Shisui is quite confident and thinks that they should go in there.

"Senpai, what do you think?"

After hearing Shisui's opinion, Itachi thinks it is better to ask Kakashi's opinion.

"Since we are all here, naturally there is no reason to give here. I know that you are all curious about this place, don't you?" Kakashi said with a smile.

Kakashi understand Itachi's worry as he also thinks that this place was indeed a bit weird, but Kakashi felt that there was something worthy inside.

Moreover, the feeling of the strange chakra made Kakashi very concerned.

It seems to have a somewhat familiar, but it is the people's chakra that he is familiar with, so what is it?

Kakashi can't think of an answer.

Then if he wants to know the answer, he can only go in and take a look.
