Under the brown waterfall, Kakashi who had his upper body naked was intently controlling the fusion of his normal Chakra and the Senjutsu Chakra inside his body.

"Kakashi-chan, Tou-chan, come over for lunch."

Shima's sudden call makes Kakashi's startled, and instantly his head starts transforming into toad's head.

Seeing this, Fukasaku took the initiative and directly expel the Natural Energy inside Kakashi's body.

"Kakashi-chan, we should stop for the time being. Let's have lunch first."

"Okay."

Kakashi puts the clothes that were on the side and wear it again.

Inside the house, Kakashi looks at the big bowl of insects in front of him and his expression shows helplessness.

Toad likes to eat this kind of thing. But he is a human being, so he has no appetite at all.

"Kakashi-chan, why don't you eat it? Ka-chan crafts are very good, so this bug is absolutely delicious."

Fukasaku said while eating a large worm in the bowl.

Seeing this, not only did Kakashi's appetite increased, he felt even more disgusting.

"Kakashi-chan, what's wrong? Why don't you eat the food?"

Shima said as she looked concerned.

"Shima-sama, I don't eat bugs, so I prepared dry food for myself."

Kakashi had already known about the insect feast here, so he prepared some dry food.

"Are you sure, Kakashi-chan? You will regret it if you don't eat this kind of delicacy."

Fukasaku said.

Hearing this, Kakashi just chuckled as the only regret is to think about eating this kind of food.

After eating, Kakashi and Fukasaku start training Senjutsu again.

Late at night, next to the waterfall, Kakashi has not continued to practice, but sits on a huge plant right now.

Fukasaku has fallen asleep so no one can help Kakashi expel the Natural Energy inside his body. Even if Kakashi wants to practice, he couldn't do it.

Fortunately, Kakashi right now didn't lack time.

Looking at the moon on the sky, Kakashi was a little emotional.

It will be September 15th in a few days, which is his 18 years old birthday. It feels just like yesterday, but now he has already lived in this World for almost four years.

Inheriting original Kakashi's emotion, wisdom and talent, Kakashi's progress in the past four years is undoubtedly tremendous.

At least at this time, he is much stronger than the original one.

Sword Skill, Lightning Release, Sharingan, plus Senjutsu.

Kakashi has already embarked on a path that is completely different from the original.

However, what these bring to Kakashi is not a sense of security, but a sense of urgency.

After four years, there is not much time left.

Sometimes in the dead of night, Kakashi would think of why he came here, and what is the reason or purpose for his rebirth.

But unfortunately, even after thinking about it for a long time, Kakashi still couldn't figure out why.

The reason why he practiced hard practice hard is because his heart is full of panic about the future.

Even if the original Kakashi manage to live to the end, this does not mean that he can do it too.

Although he has inherited everything from Kakashi, in the end, he is not original Kakashi.

Therefore, only Strength can bring Kakashi a warmth and reliance on this chaotic world.

This World is too dangerous.

Instead of pinning his hopes on the illusory original plot, Kakashi chose to strengthen himself first.

Senjutsu is a very important part of Kakashi's plan, so Kakashi must not fail training this.

After a day of practice, Kakashi found that he couldn't match Naruto's talent on Senjutsu, but he was much better than both Jiraiya and Minato.

So, even if it takes a little longer, Kakashi will definitely be able to use perfect Sage Mode.

Feeling the power of Natural Energy right now, Kakashi became more and more curious about what would happen if all of the three Senjutsu from the Three Great Holy Land merged together.

Now he is already learning the Senjutsu of Mount Myōboku, as for Senjutsu of Ryūchi Cave, he may be able to learn it from the Cursed Seal and the Senjutsu Chakra he got from Orochimaru's hideout in the past.

But Kakashi has not found a clue about the most mysterious Shikkotsu Forest's Senjutsu,.

At this time, Tsunade is the only one who has the summoning contract of Shikkotsu Forest, but he doesn't know about Tsunade's whereabout.

Therefore, Kakashi can only put aside Shikkotsu Forest's Senjutsu temporarily.

A month later, under the brown waterfall, Kakashi opened his right eye, there is faint red eyeshadow around his right eye, and the pupil in his right eye turns into yellow toad-like pupil!

Unlike Naruto's perfect Sage Mode, Kakashi's Sage Mode is still lacking, but he's not far from the perfect Sage Mode.

First Step of Sage Mode practice is completed!

"Kakashi-chan, well done. You have completed the first step of using toad oil to practice the Senjutsu. Looking at your appearance, your Sage Mode is more perfect than the Jiraiya-chan and Minato-chan."

Fukasaku said with surprise.

For a month, Fukasaku did not expect Kakashi to complete the first step so fast.

"It's not enough. I can feel that the Natural Energy inside my body is not perfectly controlled yet. So I know that it's still far from perfect."

Kakashi feels the Natural Energy inside his body is a little chaotic, and although the Natural Energy is balanced at one-third, it is still barely so Kakashi knows that there is still a gap until he perfected it.

The reason for this gap is because of his Chakra is not enough!

In the end, he is not someone with monstrous Chakra reserve like Naruto, so practicing to this level is already the limit.

If he wants to breakthrough, he must increase his Chakra reserve. Otherwise, Kakashi will never be able to perfect the Sage Mode.

"It's already very good. Kakashi-chan, the first step has been completed. The next you step is that you have to enter Sage Mode without using this oil. After all, you won't be able to use this oil outside of Mount Myōboku." Fukasaku said.

"I understand, but I have to go back to Konoha first."

Kakashi said as he grabbed his clothes and put them on.

Fukasaku had some doubts and asked: "Kakashi-chan, what are you doing back to Konoha? Haven't you completed all the arrangement before coming here?"

"There is something I need to deal with at Konoha. But rest assured, I will be back in a day."

"Well, since you insist, then go ahead."

Seeing Kakashi's insistence, Fukasaku didn't say much.

Senjutsu's practice has taken a long time, so it's kind of good for Kakashi to do something else at this moment.

If Kakashi goes back to Konoha, maybe he can relax.

"Thank you very much, Fukasaku-sama."

Kakashi said as he uses Flying Thunder God Jutsu to return to his room at Konoha.

"Ah, everything is so familiar."

Kakashi walked to the calendar that is inside this room and tore off the past calendar paper.

Kakashi turned and left, and today's date was written on the calendar.

October 10th…
