"Well, this is Chakra's cultivation method. You have to cultivate it well. When you cultivate it well, I will teach you an interesting Ninjutsu."

"What Ninjutsu?"

When he heard that he could learn Ninjutsu, Naruto was excited immediately.

"Ah, you will know about it when we get there. Remember, you must concentrate on cultivating your Chakra. Otherwise, you will not successful."

"Shiro Nii-san, in fact, I have not understood about it." Naruto touched his head embarrassedly.

Kakashi sighed. He knew that Naruto understanding ability is not good.

Since he can't understand the speech, then he need use his body to remember.

Kakashi put his palm on Naruto's back and said, "Naruto, remember this feeling well."

Naruto was going to ask something before he feels a stream of heat from his back and the heat then spreads around his body, and then gathers into his lower abdomen.

The whole process is only five seconds.

Kakashi remove his palm and asked, "Do you remember it?"

"Yes, I remember!" Naruto said with some excitement.

Although his understanding about theory is not good, Naruto's ability to learn with his body is very good, so that he can understand immediately.

"That's good, it's late now. It's time to go home."

Kakashi looked at the dim sky. It was already dark before he realized it.

Naruto originally excited little face has become a bit lonely after hearing this and thought. 'Did I have to go back to that cold home? No, that place can't be called a home, it's just a house.'

Kakashi knows what Naruto is thinking, but he didn't say anything. This is Naruto's life. He has to go on his own and he can only give him some help, but he can't help him with all the suffering.

He needs to experience this himself.

"Naruto, I will wait for you here at two o'clock tomorrow afternoon, I hope you have cultivate your chakra when we meet tomorrow."

Kakashi said that as he disappeared in a blink of an eye, leaving only a puff of smoke.

However, Naruto did not appear to be sad anymore, but smiled. He clenched his small fist and his eyes are full of spirit.

"I will do it. Wait for me!"

Hearing that they will train again tomorrow, Naruto's sadness has disappeared in an instant.

He is happy that he seems to have found a friend, although this friend looks very strange, and he is a lot older than him.

Naruto quickly ran back to his home and starts to train.

In the past three years, Kakashi has been busy with his training and his job as an Anbu. He really did not have time to find his teacher's son.

However, since they finally meet now, naturally he can't just stand by. Although he can't completely change his tragic childhood, he can at least give him a bright light in his dark childhood.

Thinking of this, Kakashi has returned to his home.

It was still early, and Kakashi did not intend to take a break and he also didn't train his sword skill.

Kakashi's sword skill is already at a high level. He didn't need to train every day. After all, he can just review his sword technique to increase his comprehension.

Kakashi then took out a Scroll from his pocket and opened it. He then sees some kind of seal runes in there.

This is the Senjutsu Chakra that Kakashi take and seal from the laboratory of Orochimaru.

And it should be Senjutsu Chakra of Ryuchi Cave, one of the Three Great Holy Land in the Legend.

Senjutsu is one of the high level skills in Naruto World. Kakashi is very interested in Senjutsu and it is also listed as one of Kakashi's goals to train in Senjutsu.

However, compared to Senjutsu of Ryuchi Cave, Kakashi feels that he may have a greater chance of getting Senjutsu of Mount Myoboku for himself.

After all, he is closer to Jiraiya than to Orochimaru.

As for Senjutsu of Shikkotsu Forest, Kakashi really doesn't know how to ask Tsunade about this.

Jiraiya is the only person he can ask. After all, Kakashi is also a grand disciple of Jiraiya. With this kind relationship, there is a good chance that Jiraiya will help him to train the Senjutsu.

It's just that even after three years, Kakashi has never seen him again.

However, Kakashi is not in a hurry. If he remember correctly, his favorite book, Icha-Icha is the birthday gift that Jiraiya gave to him when 18 years old.

If it is the same as original plot, Jiraiya will appear in front of him maybe six months from now.

Six months, half a year, Kakashi can still afford.

After three years, Kakashi's Chakra reserve has grown a lot, and learning Senjutsu should be no big problem.

Sharingan's seal has also been practiced by Kakashi to the point of perfection.

Basically, with the help of Seal's Strength, Kakashi is not affected by Sharingan when sealed.

But when he uses Sharingan in battle, his chakra consumption was still very high.

Kakashi still hasn't found a way to fix this high chakra consumption.

Looking at the Scroll in front of him, Kakashi points his fingers at the seal and take a small portion of Senjutsu Chakra.

A little white Chakra appeared in the palm of Kakashi, with a gloomy atmosphere.

"Is this Senjutsu Chakra? It is very different from the general Chakra. This chakra seems to feels like the snake type of Ryuchi Cave."

The white Chakra is like a swaying candlelight, and Kakashi tries to perceive it with his own Chakra, but without a surprise, Kakashi's Chakra is directly bounced out.

"Sure enough, Senjutsu is not so easy to learn."

Kakashi suddenly discovered that he didn't seem to have any way to do anything to this Senjutsu Chakra, and he couldn't analyze the secret.

Wait, when it comes to analyzing, there seems to be no more suitable tool than Sharingan.

Kakashi then pull up his headband, the tomoe in his scarlet left eye began to turn, and he starts to see something from the white chakra.

"This feeling… It is really complicated."

The white chakra is like a labyrinth. Even with the help of Sharingan, it is still somewhat hard to understand.

Kakashi didn't believe that he can't do it, and increases his chakra output. Then the black dart starts to appear in his Sharingan.

Mangekyo Sharingan!

"I see it! So it turns out to be like that!"

He then seals his Sharingan again, and re-covered the guard.

"Senjutsu Chakra is full of risks. This complicated structure, if I am a little careless, I am going to become a Monster. It seems that I can only go to Mount Myoboku first. If I can learn the Senjutsu of Mount Myoboku, then maybe I will be able to learn the Senjutsu of Ryuchi Cave from this thing!"

Kakashi thought as he was feeling a little excited. What would happen to Senjutsu Chakra of the two Holy Lands if they were integrated?

Kakashi is looking forward to it.

Kakashi then re-seals the Senjutsu Chakra into the Scroll, and then he placed it in a sealed box in his room.

Once someone other than Kakashi tries to open the box, it will burn directly!

Inside it is all the secrets of Kakashi, including the "Naruto World Diary" that is written in words that don't belong to this World!
