Naruto: Learn the Substitution Jutsu and use it to create Star Platinum?

"After all, it was a mission given by the Third Hokage. It would be too embarrassing for me to go back in such a sorry state."

“But even if I go back, it won’t help the war... and I don’t want to participate in wars anymore.”

Tsunade's eyes dimmed as she looked down at her hands.

"Even as a medical ninja, I..."

"Tsunade, is it because of that hemophobia?"

"Um…"

"But there's blood that Jingyin coughed up on your clothes."

"Ok?"

Tsunade's eyes widened slightly as she looked down at her chest, where the blood that Shizune had coughed up when she had hugged her earlier was stagnant.

At this moment, although she was still feeling a little unwell, she did not actually feel faint.

Lin Yi took out the Moon Blade and slashed his hand.

Fresh blood immediately gushed out.

"Tsunade-nee, come on, want to give it a try?"

Tsunade instinctively dodged away, covering her eyes with her hands.

"It's okay, sis. If you can't help me, I can treat myself, but it will hurt a lot."

Warm sunlight streamed through the broken eaves and fell on Lin Yi.

It turned Lin Yi's black hair a golden yellow.

The combination of the two colors surprisingly creates a brownish texture.

Weather forecast: You're welcome.

Tsunade slowly lowered her arm.

She stared blankly at Lin Yi, who was smiling at her.

Beneath the brown hair, the two faces seemed to overlap.

Before, after training, Rope Tree would stumble and run up to me with a silly grin.

"Sister, please use medical ninjutsu to heal me, otherwise it will hurt a lot..."

She was just afraid of being scolded by her grandmother.

As if guided by some unseen force, Tsunade gently covered her hands with the green light, then slowly placed them on Lin Yi's hands.

Lin Yi felt a cool sensation on his hand.

The wound then began to heal.

It didn't hurt at all, and it even felt a little good.

This is real treatment!

You should learn from others when it comes to the gold experience.

"Tsunade-neechan, are you... all better now?"

Tsunade stared blankly at her hands.

Looking at the bloodstains left on Lin Yi's hands, she seemed to still feel some discomfort, but it was definitely not going to affect her combat or the release of ninjutsu.

"It seems... I'm really all better."

Tsunade murmured.

"Lady Tsunade, are you alright?!"

Shizune had just woken up when she saw Tsunade cast a medical ninjutsu on Lin Yi.

"In that case, can we go back to Konoha now?"

Tsunade looked at the smile on Lin Yi's face.

He also curled the corners of his mouth into a smile.

"Konoha Hospital has been owing the director his salary for so long, and I haven't gone to collect it yet."

...

Lin Yi let out a soft breath as he waited downstairs at the hotel for Tsunade and Shizune to pack their luggage.

In Lin Yi's previous life, hemophobia was actually a mental illness.

Lin Yi, who knew Tsunade's information, could quickly guess that what caused her mental illness was nothing more than the death of her relatives and lovers, and that she was powerless to do anything about it.

So this time, he saved Shizune in front of Tsunade, which can be considered as making up for Tsunade's regret that she couldn't save Kato Dan.

Then, he would try to win Tsunade's heart, making her see him as Nawaki, to make up for her regrets about her younger brother.

A mental illness requires a mental cure, and once the right medicine is found, the illness will naturally be cured.

Although this was unexpected by Lin Yi, it seemed that this ending was even better.

Tsunade, the strongest background character in Konoha, also became his background character after Lin Yi saved the day in a crisis.

With this calculation, Lin Yi becomes Konoha's biggest backer.

As for how Tsunade encountered danger, that's none of your business.

"Alright, Lin Yi, I'm sorry to have kept you waiting."

"It's alright, Tsunade."

Lin Yi shook his head.

"I need to recover my chakra anyway, so it won't delay anything."

Upon hearing this, Tsunade subconsciously replied, "Hmm? Uchiha who have awakened their Sharingan must have a considerable amount of chakra, right?"

Lin Yi was secretly delighted.

He hadn't forgotten his purpose.

But Lin Yi, a scumbag who is well-versed in human nature, knows that it's never as good as letting the other person bring it up himself.

Although he was delighted inside, he wore a bitter smile on his face.

"It's not a small amount, but my ninjutsu consumes too much energy, so I usually carry a lot of soldier rations with me."

As Lin Yi spoke, he showed off the abundance of Azure Dragon Pills in his pocket.

"However, it's not good to eat too much of this, and it can get cloying. Now that there's no danger, we'll just slowly refine it."

Tsunade frowned slightly.

How could her brother eat such junk food every day?

"It's alright. I can't let you call me 'sister' for nothing. I happen to have a technique that can indirectly increase your chakra reserves."

Chapter 77 Returning to the Village!

Lin Yi was delighted.

Well, she said it herself.

But there was some hesitation on his face.

Is this... convenient?

"What's inconvenient about it? This is a technique I developed myself."

Tsunade waved her hand generously, stirring up a surge of waves in the process.

"Here, keep it safe."

Tsunade tossed out a scroll, and after Lin Yi caught it, her expression turned slightly serious.

The diamond-shaped mark on his forehead instantly darkened, and lines continued to spread out from the mark.

"Such powerful chakra."

Lin Yi had only ever felt this kind of chakra fluctuation when facing tailed beasts and dragon veins.

While it may not be quite as good as it could be, it is a technique developed by Tsunade herself, which is already quite remarkable.

"This technique is called Yin Seal, an S-rank medical sealing ninjutsu. It can store your usual chakra and slightly enhance your taijutsu."

However, actively releasing chakra, upon entering the Hundred Healings state, unleashes a massive amount of chakra and possesses extremely strong self-healing abilities.

After demonstrating the effects of the Yin Seal to Lin Yi, Tsunade closed the seal again.

"How about it, kid?"

"That's amazing, Tsunade-neechan."

Lin Yi exclaimed honestly, "This technique can't just be described as good, it's absolutely amazing!"

It not only met his requirements, but also provided regular passive buffs and healing effects.

According to Tsunade, as long as there is enough chakra, severed arms and legs can grow back.

Moreover, it can keep you young forever.

To be honest, Lin Yi had some doubts about whether this was Tsunade's real purpose in inventing this technique.

"Anyway, I'll be at Konoha Hospital from now on, so you can come and ask me anytime if you encounter any problems."

Tsunade, with an barely suppressed smile, gently waved her hand.

Praise depends on who gives it; if it's just an ordinary ninja, Tsunade won't care.

But Lin Yi not only saved her and Shizune, but in Tsunade's eyes, he was also a Kage-level powerhouse.

Being recognized by such a powerful figure, Tsunade naturally couldn't help but feel proud.

"Jingyin, have you packed everything?"

"It's all taken care of, Lady Tsunade."

Silently nodded her little head, carrying a large scroll on her back.

From the day she followed Tsunade, she had hoped that Tsunade would be able to walk out of this situation and return to Konoha, but she never expected that day to come so soon.
