Konoha: Starting with a sign-in for Hashirama cells

My curiosity is bursting, I can't wait to start researching.

Limited by the rules set by Naruto, Orochimaru sighed regretfully.

“From now on, he will follow you everywhere. With the Flying Thunder God Technique, it will be convenient for you to go anywhere,” Naruto said.

"Also, there's his lab, which has a lot of stuff that might be helpful to you."

Orochimaru's eyes lit up immediately.

He was extremely interested in the Second Hokage's laboratory. You see, he didn't have many idols, but the Second Hokage, Tobirama, was one of them; it wouldn't be an exaggeration to call him an idol.

His two trump cards, Impure World Reincarnation and Orochi Technique, are both forbidden techniques developed by the Second Hokage.

"Hehe, it seems that meeting you isn't all bad," Orochimaru laughed.

Naruto glanced at Orochimaru's brain, which was also Orochimaru's soul.

The Rinnegan can clearly see the closed loop formed by the power of Kotoamatsukami.

After some thought, I made sure there were no oversights. Even if there were, it wouldn't matter, as Tobirama the Second was always with me and could replenish my supplies anytime, anywhere.

They wanted to give the Seven-Tails to Hanabi so she could become its jinchūriki, but Hanabi refused.

Upon learning that the Seven-Tailed Beast was a large insect with three pairs of wings and a tail, it refused without hesitation.

"I didn't notice, I didn't ask, is Mirai Hanabi a Jinchuriki?" Naruto asked.

"I haven't noticed either." Hinata paused, thought for a moment, and shook her head.

"Kurama, did you sense the tailed beast within Mirai Hanabi's body?" Naruto asked.

"Yes." Nine Lama.

"Which one is it?" Naruto asked.

"Two-tailed." Kurama.

“Two-Tails…” Naruto pondered.

That is the tailed beast of Kumogakure, and its current jinchūriki is Yugito Nii.

Keeping this in mind, Naruto stretched and looked back.

Orochimaru and Tobirama the Second had already walked far out of sight, becoming two small black dots: "How long will it take to recover? Let's wait and see."

Hinata seemed to have made up her mind, and spoke softly, "Naruto-kun, I want to learn Sage Mode."

“Sure, if you want to learn, then learn,” Naruto said.

"I recommend you go to Shikkotsu Forest, because your Three-Tailed Fox cannot help absorb natural energy. You can rely on the Slug Sage to assist you."

"This is the method Sakura used."

"Mainly because the Slug Sage is very gentle and easy to get along with, which is quite suitable for you."

Hinata, who wanted to form a contract with Mount Myōboku like Naruto and train in its Sage Mode, hesitated for a moment after hearing Naruto's words, then nodded.

He traveled to various countries while simultaneously practicing his spiritual cultivation.

Almost two more months have passed.

Hinata mastered the Spirit Transformation Technique, which allows her soul to leave her body and train it to enhance her mental strength.

She immediately went to the Wet Bone Forest and, with the help of the Slug Immortal, began to cultivate immortal arts.

The psychic contract was established two months ago.

With Hinata gone, Naruto stopped traveling and wandered around alone. What was the point?

On the one hand, he steadfastly continued his spiritual practice in the sea, using water pressure to strengthen his body.

On the other hand, he often goes home to visit his mother, have a meal together, and tutor Hanabi in learning the Flying Thunder God technique.

His perfect immortal mode allows him to not need to sleep, giving him several extra hours compared to others, which he makes full use of.

Sweating more in peacetime will allow you to defeat your opponent in wartime, leaving no regrets and no room for remorse.

In this arduous and mundane life, the days gradually passed, until one day…

"Ding! Sign-in character triggered: Hinata Hanabi. Sign in? Yes? No?"

Chapter 157 Signing in with the One-Tailed Chakra! A Deal with Kaguya!

Is the system check-in cooldown over?

Naruto, who was brushing his teeth, froze.

"Brother-in-law, I need to go to the bathroom, hurry up!" Hanabi urged, patting Naruto's waist.

"Oh!" Naruto snapped out of his daze, quickly washed up, and slipped out of the bathroom.

"Stay calm! Don't get excited! Think about what you want to sign in next!"

Naruto went to the balcony and watered the cactus, his mind racing.

Kaguya is inside his own body. Similar to Kurama, anything inside his body is considered part of him by the system and therefore cannot sign in.

"I can try my luck with Ino's Bloodline Limit. She ate the Urashiki Fruit and gained everything from Urashiki," Naruto thought to himself.

"As for Kaguya, there is only one thing I really want to get from her: the Rinnegan with nine tomoe, also known as the Sharingan of Reincarnation."

This is the eye of the Divine Tree, the Ten-Tails, and also the most powerful eye known to date.

According to system rules, a target can only be checked in once.

To avoid losing luck and signing in with unwanted abilities, it's best to use the process of elimination.

By learning on your own, you can acquire other abilities besides the ones you want, and in this way, you can obtain the abilities you desire with 100% certainty.

"Ino, like Kaguya, possesses a host of Urashiki-like abilities, plus her own family's secret techniques..."

The secret techniques of the Yamanaka family can be obtained from other members of the Yamanaka clan. You can't just go and ask Ino for help; that would be too risky.

After much thought, there are two check-in routes to choose from.

One is the chakra of the tailed beasts that I sign in with.

The God Tree Chakra was divided into nine parts by the Sage of Six Paths, which were then used to create the nine Tailed Beasts. Conversely, the nine parts were combined to form the God Tree Chakra.

Nothing related to the Divine Tree is simple, let alone something as crucial as chakra.

The other option is to sign in to the Yamanaka family's secret manual. If you rule out this option, try your luck with Ino and hope to obtain the Bloodline Limit.

There's a cooldown period for signing in; choosing one path means the other path will be suspended for a while.

"You can't rely on luck. Success is great, but what if I fail and end up with a useless, insignificant skill? That's..."

Naruto slapped his thigh, making up his mind to follow the path of the Divine Tree Chakra.

In order to deal with this situation.

Back in the third round of the Chunin Exams, after Orochimaru launched the Konoha Crush plan, Naruto asked Jiraiya to help seal some of the One-Tailed Chakra.

Because of this, the Nine Lamas often caused trouble.

Having made his decision, Naruto immediately found the scroll, unsealed it, and released the One-Tailed Chakra within.

"That's all that's left!"

When it was first sealed off, it was the size of a four-story building; now, it has shrunk to the size of a water tank.

The chakra of the tailed beasts is several levels higher than that of humans.

Note that Hashirama Senju is not human, or rather, he cannot be considered human.

Chakra is much better than that of humans after it leaves the tailed beasts, but it cannot be maintained for a long time. After a certain period of time, it will naturally evaporate.

Sealing it in a scroll can only slow down the evaporation rate, not stop it.

The reason why Mito Uzumaki and Tsunade's Yin Seal can be classified as S-rank is due to its difficulty in learning, but even more so to its effectiveness.

The perfect combination of the human body and sealing techniques makes the impossible task of storing chakra possible.

"Ding, a sign-in creature has been triggered: One-Tailed Chakra. Sign in? Yes? No?"

Yes.

"Congratulations, you have obtained the perfect One-Tailed Chakra."

Kaguya Otsutsuki, the new resident who had remained silent after realizing she couldn't escape, sensed something and couldn't help but ask, "What did you do?"

Having ideas but lacking the ability to implement them, and feeling depressed, Black Zetsu asked in confusion, "Mother?"

"Want to know?" Naruto said, "Trade something for it."

"What can I offer right now?" Kaguya asked.

“Of course there are,” Naruto said. “All the abilities you possess are examples of that.”

"So that's what you were planning," Kaguya said. "I don't trust you. You've deceived and played me for a fool time and time again."

“Because what you’re about to do will destroy this world, of course I can’t let you succeed,” Naruto said.

"I won't lie to you this time. I can say this out loud: I will do everything in my power to make our deal happen, as long as it doesn't endanger the world."

"You are welcome to give it a try."

Kaguya thought for a moment: "My abilities are all based on bloodline limit. You don't have bloodline limit, so you can't learn them."

"Whether I can learn it or not is my business. You just need to offer your bargaining chips," Naruto said.

"What do you want to learn?" Kaguya asked.

“I want to learn any of your abilities,” Naruto said.

This is in preparation for signing in with the Nine-Tomoe Rinnegan in the future.

“Okay,” Kaguya said, “but let’s make it clear first, I won’t fulfill my promises if I don’t get a result that satisfies me.”

“Of course,” Naruto said.

Climb out the window and onto the roof.

Without Naruto making any move, a large number of cursed seal patterns suddenly appeared on his skin.

Looking at his hands, Naruto felt a bit scared; his trypophobia was about to kick in. He closed his eyes to calm himself.
