Worries, Training Plan

"Compared to this guy, even Hashirama Senju, with his Sage Body, probably couldn't measure up, could he?"

On Half-Moon Island.

Takenaka Kaguya thought to himself, but his movements did not slow in the slightest. After all, he had to pretend he had not noticed Black Zetsu's arrival. That sword energy just now had to look like an unintentional act as well.

Otherwise, if Black Zetsu set his sights on him, there would be no end of trouble in the future.

After all, Black Zetsu's skill at talking people into things was probably only slightly worse than Naruto Uzumaki's. Otherwise, how could he have managed to fool even Madara Uchiha so thoroughly?

Not far away, deep underground, Black Zetsu's expression was extremely ugly. However, when he sensed that Takenaka Kaguya was still training, he finally breathed a sigh of relief and thought, No wonder he caught Madara Uchiha's eye. With strength like this at such a young age, given enough time, he might truly grow into an expert comparable to Madara Uchiha and Hashirama Senju.

It seems I'll need to keep a closer eye on him from now on. Hopefully, he won't become an obstacle to rescuing Kaguya Otsutsuki. Otherwise, things will become very troublesome.

It could only be said that although the two had not exchanged a single word, they seemed to share an unspoken understanding.

Neither had any intention of meeting the other, yet both were wary of each other.

Time passed. Black Zetsu watched Takenaka Kaguya for half an hour. When he saw that Takenaka Kaguya was still training, training, and training, he lost interest. He quietly sank back into the earth and disappeared into the sea.

Once Takenaka Kaguya's Advanced Observation Haki could no longer detect Black Zetsu's presence, he finally stopped wielding Shusui. Standing by the shore and looking toward Black Zetsu's departing figure, he muttered, "I still need to increase my strength as quickly as possible. According to the current timeline, Madara Uchiha left Konoha in the second year after Konohagakure was founded. And it's very possible that Madara Uchiha has already come into contact with Black Zetsu.

"Once Madara Uchiha leaves Konoha, if Black Zetsu sees me as a threat, he may very well incite Madara Uchiha to come and kill me.

"So no matter what, before Madara Uchiha leaves, my strength must at least reach the Half-Step Six Paths Level if I want to contend with him.

"Otherwise, even if I use the Life-Saving Talisman given by the system, once it is consumed, my safety will no longer be guaranteed."

Thinking of this, Takenaka Kaguya asked the system in his mind, "System, can you formulate a training plan based on my current condition and help me raise my strength to the Half-Step Six Paths Level in the shortest possible time?"

"Ding. Host request received. A training plan can be formulated.

Please wait a moment, Host. Calculating..."

"Phew!"

As the system's voice echoed in his mind, Takenaka Kaguya let out a breath. With the system's help, he felt much more at ease.

After all, compared to himself, the system's capabilities were incredibly powerful. Yet even now, he did not know why it was helping him for free.

Of course, perhaps the system did not tell him because he was not strong enough yet. Maybe one day, when his strength reached the peak of the Naruto World, the system would take the initiative to tell him.

About ten minutes passed before the system's voice sounded in his mind. "Ding. The Host's training plan has been completed. Based on the Host's current abilities, raising your strength to the Half-Step Six Paths Level will require training in three areas.

"First, when the Host meets Mito Uzumaki, you may ask her for the Yin Seal. With the Yin Seal, the Host can increase Chakra reserves and improve combat endurance.

"Second, the Host's Armament Haki has already reached the intermediate level. Training it to the advanced level may allow you to step into the Half-Step Six Paths Level.

"Since the Host's physical functions have not yet reached their peak due to age restrictions, a specialized Armament Haki training plan has been tailored for the Host. Please receive it.

"Third, Sage Mode. The Host's Sage Mode is currently at the beginner level. You may return to the Kaguya Clan's Forbidden Grounds to continue training. Once the first two conditions are also fulfilled, the Host's overall strength can reach the Half-Step Six Paths Level."

As the system's voice faded, Takenaka Kaguya fell silent for a moment.

The Yin Seal had been developed to its utmost extent by the Fifth Hokage, Tsunade, in the original work of Naruto. However, its true creator was Mito Uzumaki.

As an S-rank medical Sealing Jutsu, once the Yin Seal was mastered, a diamond-shaped mark would appear on one's forehead. By finely regulating Chakra, it could achieve instant healing, strengthen attacks, and increase speed.

At a deeper level, one could combine the low-output Chakra of the Strength of a Hundred Seal with fine regulation to preserve one's youthful appearance, enhance bodily functions, and keep the body in peak condition.

However, according to Takenaka Kaguya's estimate, Mito Uzumaki had already completed the development of this S-rank Sealing Jutsu, the Yin Seal.

Given his relationship with Mito Uzumaki, obtaining the Yin Seal from her might not require too great a price.

From their interactions, he could tell that Mito Uzumaki truly treated him as a younger brother. Moreover, Hashirama Senju had always been friendly toward him and had even hoped that he would come live in Konoha.

If he had not killed so many Konoha Ninja on the battlefield before, including one member of the main family and several members of the branch family of the Hyuga Clan, which had a good relationship with the Kaguya Clan, he estimated that he might truly have accepted Konoha's invitation.

"Alas!"

Thinking of this, he could not help sighing. On the battlefield, it had been a fight to the death. Those people wanted to kill him, and he could not possibly refrain from killing them in return.

"After some time, I can make a trip to the Land of Whirlpools and obtain the Yin Seal.

"Hiss!"

Suddenly, as he muttered to himself and opened the Armament Haki training plan provided by the system, he could not help drawing in a sharp breath. Astonished, he said, "System, training Armament Haki under the sea with the pressure of seawater? Are you serious? Aren't you afraid the pressure will crush me to death?"

"Ding. This training plan was customized based on the Host's current physical condition. Please do not doubt this system's capabilities," the system's cold voice replied.

"Fine, if that's the case, I can only follow it.

"But the problem now is that training Sage Mode requires returning to the Kaguya Clan's Forbidden Grounds. My relationship with Kirigakure has now fallen to rock bottom. If I go back at a time like this, that narrow-minded Hozuki Gengetsu may suspect that I'm returning to compete with him for the position of Second Mizukage.

"I'm not worried about myself. No matter what tricks he uses, I can deal with them easily.

"But if I enter the Kaguya Clan's Forbidden Grounds, Aunt's safety cannot be guaranteed. What should I do?"
