Warlock Invasion of Naruto.

Furthermore, as he is the grandson of the First Hokage, the chances of healing his severed leg will be much greater once medical ninjutsu reaches a level where it can utilize the First Hokage's cells.

This is a conclusion that Bai Yu reached through research. The reason he didn't mention it is because the First Hokage's cells were strictly sealed, and Tsunade didn't have the authority to access them. However, now, because of Nawaki, there should be hope of obtaining them.

This approach offers the hope of curing Nawaki and also allows Shiraha to obtain the first generation of cells.

Based on speculation, the first generation of cells should meet the criteria for cells of a super-radioactive organism.

Although Bai Yu hasn't even reached the third-level apprentice level yet, it's very necessary to prepare in advance for promotion to a first-level sorcerer.

Once he advances to the level of a first-class warlock, not only will his strength increase, but his mental and magical abilities will also undergo a qualitative change, which will greatly help his research on cellular technology for limb regeneration.

"Sister...is this true?" Nawaki subconsciously looked at Tsunade, after all, his sister was a medical expert.

"Theoretically... that's possible." Tsunade looked at her brother's heartbreaking eyes and nodded with difficulty. "But..."

"The chances are slim!" Bai Yu finished Tsunade's sentence, then added:

"Rope Tree, current medical technology cannot achieve this, and it may not be able to achieve it in the future."

Even Tsunade-sensei couldn't guarantee that.

But... I believe I can!

I will dedicate my life to overcoming this technical challenge!

This is a promise between men!

"Baiyu!" Nawaki suddenly burst into tears.

His facade of strength was shattered by Bai Yu.

Tsunade couldn't stop crying, feeling sorry for her younger brother, but also moved by Bai Yu's sincerity and ambition.

Even though Mingyu hadn't given up, her older sister, who was known as a "medical expert," subconsciously "gave up" in her heart.

"Rope Tree, I will work hard with Shiraha! We will definitely heal you!"

"Sister—!" Rope Tree let out a heart-wrenching cry. Pain, grievance, regret—all sorts of emotions intertwined.

The guards outside were startled and rushed in to check the situation.

Seeing the siblings hugging and crying, he withdrew.

"Kushina..." Bai Yu whispered a reminder, then left the ward with Kushina, leaving the siblings alone.

It's definitely better to let Nawaki fully vent his emotions than for him to pretend to be strong.

Because the most difficult part is yet to come, and he will have to persevere on his own.

......

Due to the Eight-Tails' attack in Kumogakure, the Anbu who had recently stopped monitoring Kushina has reappeared, but there is only one of them.

Even so, Shiraha and Kushina could not speak freely, and as a result, the time Kushina spent chatting with Kurama was also greatly reduced.

That day, Kushina stayed at Shiraha's house until dark, and the two of them lay on the sofa watching TV programs.

Television came into being in this era, but there were very few programs, just enough to pass the time after dinner.

After the incident with Nawaki, Kushina seems to have become even more dependent on Shiraha.

"Kushina, it's too late, let me take you home."

Bai Yu glanced at the time and gently nudged Kushina, who was sleeping against his shoulder.

Kushina rubbed her sleepy eyes and put down the cat-shaped pillow she was hugging. "Hmm... what time is it?"

It's almost 9 o'clock.

Bai Yu escorted Kushina all the way to a large courtyard near the outskirts of the village.

Speaking of which, aside from sleeping at night, Kushina spends more time at his house than at her own home.

"Kushina, don't overthink it, get some rest," Bai Yu said softly, seeing that Kushina was in low spirits.

"Yes! Bai Yu, I will work hard in my cultivation and protect you well in the future."

Kushina's expression suddenly turned serious.

Bai Yu paused for a moment, then laughed and said, "Shouldn't I be the one protecting you?"

"You're so weak, of course I'll protect you."

"..."

Heartbroken.

He's not weak, okay?

Kushina is just too overpowered!

Now that Kurama (the Nine-Tails) is no longer causing trouble, Kushina's strength is improving rapidly.

Most importantly, she seems to have found the motivation to become stronger, and her enthusiasm for cultivation has surpassed that of Bai Yu.

"Hmph! Don't be so smug. I'll catch up with you sooner or later, and then..." Bai Yu didn't say "I'll pin you down" because, considering the power of Kushina's punches, he didn't dare to overstep his bounds for the time being.

"We'll see later, goodnight." Kushina jogged away into the yard.

Bai Yu smiled and waved.

Based on the Nine-Tails' chakra he sensed, it could only be described as unfathomable, like an abyss or the sea.

If Kushina could reconcile with Kurama and fully control Kurama's power, Bai Yu felt that even if he advanced to a level 2 sorcerer or even a level 3 grand sorcerer, he might not be able to handle it.

Kushina has such high potential for development, at least her future safety is guaranteed, which puts Bai Yu at ease a little.

He might really have to live off his wife for most of his life!

......

Bai Yu returned home and began tidying up the messy coffee table, then organized the bookshelf next to the television.

He prefers to curl up on the sofa rather than read in his room.

Ding Dong!

Just as Bai Yu finished tidying up and was about to go upstairs to meditate, the doorbell rang in the entryway.

"Did you leave something behind again?" Bai Yu looked at the sofa that had been cleaned and assumed that Kushina had returned.

When he opened the door, an unexpected person appeared at the door—Orochimaru.

"Lord Orochimaru?"

Bai Yu was stunned for a moment.

"I apologize for the late visit," Orochimaru said politely, his voice noticeably hoarseer than before.

"It's no trouble at all, it's my honor to have you here. I don't know..." Bai Yu said respectfully. He guessed that Orochimaru might have seen Nawaki and then learned about what he had said that afternoon.

"I came to you to ask if you are really confident? Are you determined to dedicate your life to conducting research on that child, Nawaki, even if the prospects are slim?" Orochimaru stared intently at Shiraha, as if trying to see through him.

Bai Yu said seriously, "Yes! But it's not just for the sake of the rope tree. I like to explore the unknown. Science and research are endless, and anything is possible!"

"Science and research... are endless, anything is possible, you really dare to say that. Cough cough cough!"

Orochimaru chuckled, followed by a violent cough, his pale face flushed with a sickly redness.

"I will conduct research in this area after this war is over, and you can come with me then."

I want to see if you are as talented as Tsunade says.

Before that, you should figure this out first.

After saying that, Orochimaru took out a scroll from his pocket and handed it to Shiraha before turning and leaving.

Bai Yu opened the scroll and his eyes lit up immediately.

We gave him something so precious.

Clearly, Orochimaru wanted to seize every opportunity to cure Nawaki.

Bai Yu was even more puzzled.

Why did Orochimaru, who doted on Nawaki and valued the master-disciple relationship so much, ultimately choose to kill his master?

[Chapter 35. Class Assignment and Unexpected Events]

Tsunade did not stay in the village for long. On the third day after Nawaki woke up, she and Orochimaru rushed to the front line.

Jiraiya alone is almost unable to withstand the fierce attack from Sunagakure.

The most crucial factor was the poison developed by Chiyo, the advisor of the Sand Village's Kazekage, which no one could cure.

The morale of Konoha is low.

However, the situation quickly reversed soon after Tsunade arrived at the main battlefield on the western border.

Not to mention that her arrival and Orochimaru instantly added two top-tier combatants, the most crucial thing is that Tsunade cracked Chiyo's specially made poison in less than ten days.

With its advanced medical ninja system, which surpassed that of other countries, Konoha quickly dispatched a steady stream of finished medicines and various resources to the front lines after the antidote formula was delivered to the village.

After the poison was neutralized, the Sand Village's puppeteer forces lost their "sharp teeth" that allowed them to dominate the battlefield.

As the strongest ninja village in the ninja world, Konoha has ninjas with very high overall quality.

However, Sunagakure is not a small ninja village like Amegakure. As one of the five great ninja villages, it is not something that Konoha can defeat Sunagakure in a day or two.

The Third Kazekage of Sunagakure, known as the strongest Kazekage in history, was unable to defeat the combined forces of Tsunade, Orochimaru, and Jiraiya, and was repeatedly repelled.

The Third Kazekage was already over forty, which is the peak of a ninja's life. After the age of 50, a ninja's various physical functions will decline significantly.

Keep in mind that the three legendary Sannin are only twenty-five or twenty-six years old, and are in their prime.

This battle marked the true beginning of the legendary Sannin of Konoha's fame resounding throughout the ninja world.

Because the Third Hokage of Konoha is still stationed in the rear, Sunagakure does not dare to gamble everything.

The border battlefield became a meat grinder, with hundreds and thousands of ninjas being devoured by blood and fire.

When a war cannot be won quickly, it inevitably devolves into a war of attrition, at which point both sides must test their resources and strength.

And this is precisely Konoha's strength.
