The Second Ninja World War Begins

Natsuki returned to the Laboratory at Konoha Hospital.

But this time, besides him and Tsunade, there were five more medical Jonin.

"I called you here to learn about a new potion."

Tsunade got straight to the point. "Natsuki, demonstrate it for us now."

The five medical Jonin could not help but look surprised.

Had Natsuki invented this new potion?

Natsuki was now Orochimaru's student and fairly well-known in Konoha.

They all knew about him, but hadn't they heard that he had exceptional talent in Sword Technique? How did he also have a talent for inventing new medicine?

Geniuses really were beyond expectations.

Natsuki nodded.

He took out seven medicinal ingredients from the medicine cabinet and began extracting them.

Tsunade and the others watched his movements attentively like students, memorizing every step.

After a long while, a Blue Healing Potion was freshly produced.

"All of you, try it."

Tsunade handed the Blue Healing Potion to the five medical Jonin.

The five medical Jonin each took a small sip.

Very quickly, shock appeared on their faces.

Its effects far exceeded their expectations.

Five seconds to take effect sounded slow, but compared to other medicines, it was already extremely fast.

"Natsuki, watch what I do. If anything is wrong, point it out."

After saying that, Tsunade took out seven medicinal ingredients.

Natsuki's gaze fell upon her hands.

After watching for a while, he could not help but sigh. As expected of the finest medical Ninja—she had perfectly replicated it after seeing it only once.

Tsunade picked up the Blue Healing Potion, examined it twice, and nodded.

The techniques Natsuki had used were fairly basic.

As long as they knew the formula, most medical Ninja would be able to make it without issue.

That was undoubtedly a good thing.

Because mass production would be easy.

"Get familiar with the production process."

After saying that to the five medical Jonin, Tsunade looked at Natsuki again. "Come with me."

Natsuki nodded and followed her into her office.

"Wait a moment. I'll draw up a contract for you."

After sitting down, Tsunade took out a blank scroll.

Natsuki sat on the sofa and looked at her.

But because of his height, he could see beneath the desk at a glance.

There was a pair of long, well-proportioned feet, their pale curves smooth and graceful.

Five delicate toes were pressed together, and their red-painted nails were especially eye-catching.

"I'm done. Sign it."

Tsunade stood up. Her toes pointed downward, and the pressure made the skin of her feet flush faintly red.

She took a few steps toward Natsuki and leaned forward. Her clothes curved with her body, looking as though they might slip loose at any moment.

Natsuki glanced at her before shifting his gaze to the scroll.

The contents of the scroll were what Hiruzen Sarutobi had mentioned before.

Thirty percent of the profits from the Blue Healing Potion would go to Natsuki.

Tsunade's signature was already at the bottom, but two spaces had been left blank.

Obviously, they were for Natsuki and Hiruzen Sarutobi.

After reading it, Natsuki wrote his name on the scroll.

He handed the scroll to Tsunade and said, "Thank you, Teacher Tsunade."

Tsunade could not help but smile. She reached out and ruffled his hair.

Taking the scroll, she said, "Konoha should be thanking you. Without your Blue Healing Potion, there wouldn't be this contract."

After chatting with her for a while longer, Natsuki took the initiative to leave.

The Blue Healing Potion had achieved the results he expected according to plan. Next, he would temporarily put potion-making aside.

After all, there was no way to make the Red Healing Potion: Blood of God or the Stamina Recovery Potion anytime soon.

"Teacher."

Natsuki entered Orochimaru's study.

"What is this?"

Orochimaru looked at the Blue Healing Potion Natsuki offered him and asked.

"It's a new medicine I accidentally created."

Natsuki replied.

"...?"

Orochimaru froze for a moment, then took a sip of the Blue Healing Potion.

Feeling the changes in his body, he could not help but feel somewhat surprised.

"Very good."

Orochimaru did not hold back his praise.

To independently create a Blue Healing Potion at the age of seven—even he could not have done that.

"You may continue."

Orochimaru paused, then said, "But do not let it delay the growth of your strength."

"Yes, Teacher."

Natsuki nodded, then added, "Other than Dance of the Crescent Moon, I've already mastered all of Konoha Style Swordsmanship."

"Then today, I'll teach you Uchiha Style Sword Technique."

Orochimaru smiled faintly.

Under normal circumstances, Ninja outside the Uchiha Clan could not learn Uchiha Style Sword Technique.

But as Hiruzen Sarutobi's student, Orochimaru naturally had ways to learn it if he wanted to.

Shimura Danzō was even more outrageous—he had learned Izanagi, the Uchiha Clan's forbidden technique.

Natsuki immediately thought of Uchiha Shisui.

By combining Uchiha Style Sword Technique with Fire Release, he had created Nintaijutsu such as Uchiha Style Sword Technique: Sword Leap Flame.

Nintaijutsu was Taijutsu combined with Ninjutsu.

In the Ninja World, Sword Technique could also be classified as Taijutsu.

Natsuki began learning Uchiha Style Sword Technique from Orochimaru.

He quickly confirmed his suspicion. Nintaijutsu like Uchiha Style: Sword Leap Flame had been created by Uchiha Shisui himself.

No other Uchiha Ninja had used it in the original work, either.

The next day arrived.

Konoha Hospital had already begun producing Blue Healing Potions at full capacity, but it had nothing to do with Natsuki.

He only needed to lie back and collect money.

The morning was still devoted to theory class.

After it ended, Natsuki had lunch with Uzumaki Kushina, Yakushi Nonō, and Namikaze Minato.

"I'll train with you for a while."

After lunch, Namikaze Minato caught up with Natsuki and spoke.

"Does Lord Jiraiya have a mission?"

After thinking for a moment, Natsuki asked.

"You guessed it right away. You really are perceptive."

Namikaze Minato was slightly startled.

"It wasn't hard to guess."

Natsuki explained, "Teacher Tsunade is a medical Ninja. If Lord Jiraiya didn't have time, he would definitely have you come find my teacher."

"Teacher went to the Land of Rain to investigate intelligence."

Namikaze Minato's expression turned serious. "If nothing unexpected happens, a war will break out in the Land of Rain."

Natsuki's heart jolted.

Was the Second Ninja World War about to begin?

But fortunately, he still had time.

Because the Second Ninja World War lasted three or four years.

With the Land of Rain as the battlefield, Konoha, Sunagakure, Amegakure, and Iwagakure took turns entering the fray and fighting one another fiercely.

Konoha fought major battles against Amegakure and Sunagakure one after another.

The two most famous were the battles that made the Legendary Sannin and Tsunade famous.

The former was Tsunade, Jiraiya, and Orochimaru fighting Hanzo.

The latter was Tsunade fighting Chiyo, staging a war between medical Ninja.

Of course, the greatest impact of this war was the birth of Akatsuki.

But for Natsuki, there was one more matter that required attention: the destruction of the Uzumaki Clan.

"If the war fully breaks out, we might graduate early."

Namikaze Minato spoke heavily. "We need to become stronger as quickly as possible."

Natsuki nodded.

In the original work, both Namikaze Minato and Uzumaki Kushina graduated at the age of ten, just when the Second Ninja World War was at its fiercest.

"Minato, do you know anything about Uchiha Mikoto?"

After thinking for a moment, Natsuki asked.

"Do you want to challenge her?"

Namikaze Minato immediately understood.

After all, Natsuki had previously challenged Nara Shikaku and the others.

"The Uchiha Clan is famous throughout the Ninja World. I also want to see the legendary Sharingan for myself."

Natsuki admitted it.

"She's the top student in sixth grade, so her information shouldn't be difficult to find. Leave it to me—I'll ask around tomorrow."

Namikaze Minato readily agreed.

Because he felt that he could learn from Natsuki and challenge upperclassmen as well.

Since that was the case, he might as well gather some information.
