Naruto: We are invincible

"Forget it, let's not talk about him anymore." Naruto waved his hand and ended the topic. "We will make a decision after he comes back from the exam."

"Alright," Tsunade agreed reluctantly, "How's the old guy doing?"

"Sai knows nothing about his plans. Like I said, he's just a tool and didn't even know about the mission until the last minute." Naruto explained, "I don't know what Danzo is planning. You'd better be careful and pay more attention to his movements."

"I would have paid attention even without you telling me. Although I am a woman, I didn't become Hokage by relying on my looks." Tsunade said with a smile, "I have been keeping an eye on him. He has been very honest in recent days."

"Of course I won't look down on you, grandma." Naruto said with a smile.

"Then what are you doing here?" Tsunade asked suspiciously.

Naruto would not come to the library unless he was here to study some new ninjutsu.

Her eyes scanned the books Naruto had brought and she froze.

When she saw the titles of those books, a chill ran down her spine.

A long-forgotten memory suddenly emerged in her mind.

##remember##

"I say Orochimaru, stop reading, we should go." The young Tsunade said to her companion.

Orochimaru was sitting in a chair, concentrating on the book in his hands. The table was piled with various documents, scrolls and sketches.

He sighed a little impatiently.

"With you two around, I'll never be able to do some research in peace." Orochimaru complained secretly in his heart, turned his head and saw Jiraiya waving at him.

Next to Jiraiya stood Tsunade, who was leaning against the wall, impatience written all over her face.

"I've had enough." Tsunade said, walking straight towards Orochimaru.

She came up behind Orochimaru and secretly glanced at the book on his desk, wondering what it was that fascinated him so much.

She saw some sketches of the human nervous system, some notes on cell division, and some random things that seemed to have no clue. She turned her eyes to the pile of books.

Human Biology

Oxidative medicine and cell lifespan

Mitosis and Meiosis

Cell Immortality

"Immortality: Myth or Reality?"

"Orochimaru..." Tsunade looked at the books, then looked at the expressionless Orochimaru, "Are you serious?" Her tone was full of surprise and disbelief.

"Perhaps, life is meaningless..." Orochimaru said calmly, as if he was a little dissatisfied with being interrupted, "But if you stay in this world for a while longer, you will find something valuable..."

"Are you serious?" Tsunade asked, "You mean, there is no point in living?"

"On the contrary." Orochimaru looked at Tsunade and said with a smile, "I desire eternal life more than anyone else. Fear is the stumbling block that hinders our progress. Why can't we pursue immortality?" Orochimaru said as he tidied up the things on the table.

“People are like this. Only when they lose something do they realize how precious it is. And I don’t want to lose anything.”

"You... you studied these things because of your parents?" Tsunade asked softly. Orochimaru's body trembled slightly.

"Don't ask so many questions, I'm just doing this for myself." Orochimaru said, and walked out of the room without looking back. Seeing this, Tsunade had no choice but to follow him.

"Why?" Tsunade seemed to be determined to get to the bottom of the matter.

"I want to learn all the ninjutsu, I want to understand the truth of this world." Orochimaru said, and disappeared at the end of the corridor.

##End of memories##

"Naruto." Tsunade said in a serious tone, "You are grown up now and should know what to do and what not to do."

Naruto looked at Tsunade blankly, not knowing what she wanted to say.

"I once had a very good friend who was led astray by what you are researching. No matter how much Jiraiya and I tried to persuade him, he refused to turn back. He became more and more obsessed with his research, and he was willing to abandon everything, including his humanity, to achieve his goal."

"You mean Orochimaru, right?"

Tsunade nodded.

"I will never be like that," Naruto said firmly.

After hearing Naruto's assurance, Tsunade showed a relieved smile on her face.

"I know you will never become like him. I just want to remind you to be careful and not let those things lose your mind."

Naruto nodded, indicating that he understood what she meant.

"But I believe in you," Tsunade said, patting Naruto's shoulder.

After saying that, he turned and left, leaving Naruto standing there alone, lost in thought.

## Meanwhile, in the Hidden Cloud Village ##

While Naruto and Tsunade were talking, Hinata was working hard on her newly created ninjutsu.

If all goes well, she will have two more S-rank ninjutsu added to her arsenal.

At this moment, she was in the center of a small pool of water, which she had created using her chakra.

She is trying to practice water-style ninjutsu to perfection.

Several water columns rose slowly from the pool, spinning and dancing rapidly around her, but did not hurt her at all.

Hinata slowly opened her eyes and focused on her right hand.

The Byakugan activated! She mobilized all the chakra in her body to control the changes in the water flow.

Her right hand began to become soft and transparent, and gradually turned a light blue.

But just when her right hand was about to turn completely into water, the chakra in her body suddenly became disordered, and her right hand returned to its original state, only becoming a little dehydrated.

"It's been almost two months, and this is all I can do..." Hinata couldn't help but frown, but she didn't give up and still gritted her teeth and persevered.

She took a deep breath and was about to try again when she heard hurried footsteps and a familiar roar.

"Hinata!"

She immediately recognized that it was Shikamaru's voice.

Moreover, his tone sounded more panicked and desperate than usual.
