Warlock Invasion of Naruto.

"I've already sold myself to you, what are you still worried about? Actually, you should have expected this class assignment result a long time ago."

"Hmm." Kushina nodded. She had expected that the Third Hokage would not let her, the Nine-Tails Jinchuriki, leave the village so easily, but she was still somewhat unwilling.

“However, if you have any complaints, you can still voice them to the Third Hokage,” Bai Yu said with a smile. “That’s more in line with your... straightforward personality.”

"?" Kushina glared at Shiroha. Was he about to say 'violence'?

"I...I'm going back first, I still need to wait for the Jonin instructor!" Bai Yu quickly made up an excuse to slip away.

Next, I'll be working with the team, so I need to get to know my teammates as soon as possible.

Bai Yu returned to the classroom and headed towards the back mountain of the school as instructed.

The meeting point for Class 12 is here.

When Bai Yu arrived at the agreed location.

A man in his thirties, dressed in a Jonin uniform, was sitting on a large rock. He had a cross-shaped scar on his left cheek and a standard ninja sword slung over his back.

Just like in the photo, he looks somewhat serious.

On either side of Oshima Shuichi stood a person. The girl on the left was about fourteen or fifteen years old, with short hair that reached her ears. She was very pretty and was Uchiha Chiho.

As for the boy standing on the right, he was about the same age as Uchiha Chiho, with fair skin and an expressionless face.

He has white eyes and is clearly another teammate of Shiraha, Hyuga Eito.

Elite Jonin + Hyuga + Uchiha + Common Healer = Powerful DPS + Scouting + Support DPS + Healing

A perfect team.

It seems the village is probably piloting a model to make the elite squads a complementary system like the "pig-deer-butterfly" system.

"Sorry I'm late." Bai Yu glanced at it briefly before looking away.

"It's not late, as long as you're punctual." Oshima Shuichi smiled slightly and said:

"Because you were added as a supplementary member."

Only through mutual understanding can the ability to collaborate as a team be improved.

So let me introduce myself first. My name is Hideichi Oshima, and I am your instructor, a Jonin.

He is skilled in Fire Release and Wind Release techniques, as well as swordsmanship.

Bai Yu picked up the conversation: "My name is Yagami Bai Yu, and I am skilled in taijutsu and medical ninjutsu."

As for ninjutsu, I only learned Shadow Clone Jutsu, but I can only create one clone.

This year I officially passed the medical training course assessment, and my goal is to become a medical expert like Tsunade.

Since the Third Hokage already knew about Shiraha learning Shadow Clone Technique through the 'Telescope Technique,' there was no need for him to hide it.

As for his medical ninjutsu skills, he ranked first in this training course.

He seems to be the kind of support ninja with decent ninja talent, so-so combat ability, and strong medical ninjutsu talent, which surpasses most medical ninjas.

Of course, for ordinary people, Bai Yu is already an absolute genius!

"My name is Uchiha Chiho. I have awakened a single-tomoe Sharingan and am skilled in ninja tool throwing and fire release techniques. Please take care of me." Uchiha Chiho smiled, as if she had forgotten her previous unpleasantness with Shiraha.

However, in Bai Yu's opinion, her smile seemed somewhat fake and stiff.

"Hyuga Hidetoshi, skilled in the Byakugan and Gentle Fist, please guide me." Hyuga Hidetoshi, who introduced himself last, was rather aloof, but still very polite.

That makes sense, especially in wartime like now, any squad with a medical ninja would be very happy.

At least you won't be ostracized; no one can guarantee they won't get hurt.

"A new member joined today, so we're giving him a day off." Oshima Shuichi didn't say much more, standing up from the large rock. "I'll treat everyone to a meal later to welcome the newcomer. Eat as much as you like!"

"Then I won't be polite." Bai Yu smiled happily.

......

After the meal, Bai Yu went to the training ground with the team for some activities.

Bai Yu felt that when Oshima Shuichi fought him, he couldn't hide the murderous intent in his eyes.

It seems he ate a bit too much for lunch!

Ultimately, Oshima Shuichi changed the battle plan based on Shiraha's combat (self-preservation) level.

As Bai Yu had anticipated, they carried out normal tasks together, and when faced with high-difficulty tasks, he would provide as much support as possible to his teammates while ensuring his own safety.

Finally, Oshima Shuichi emphasized that in the event of force majeure, Shiraha could prioritize evacuation.

To put it bluntly, it means abandoning the mission and running away.

This is hard to imagine for ordinary ninjas, but medical ninjas are special.

Even during wartime, enemy soldiers who capture medical ninjas are usually not killed outright. They are often exchanged as prisoners later on, an unwritten rule among nations.

After all, training a medical ninja with good overall abilities may cost more than training an ordinary Jonin.

Of course, given the specific circumstances, probably no one would be willing to try it.

Bai Yu wisely indicated that he would obey orders.

Judging from her chakra reaction, Uchiha Chiho surpasses that of an average Chunin. With her one-tomoe Sharingan and her talent, her combat strength is definitely very strong.

Hyuga Hideto is no pushover either.

The two are much better than Sakamoto and Midorikawa.

Most importantly, the team's safety is greatly guaranteed after acquiring the Byakugan. Bai Yu's "sixth sense" observation radius is now far inferior to that of the Byakugan.

......

"Mission begins tomorrow. Dismissed."

In the evening, when the party was dismissed, Oshima Shuichi left these words and departed immediately.

They didn't mention inviting me to dinner again.

The other two teammates also left separately, showing no intention of deepening their relationship with Bai Yu.

Shiraha then went to find Kushina.

After the meal, Kushina mysteriously brought Shiraha to her home.

She took out a large box from the underground chamber.

When the box was opened, it was filled with scrolls of various colors.

"Kushina, what is this...?" Bai Yu asked with a puzzled look.

"These are sealing techniques and ninjutsu of the Uzumaki clan," Kushina explained.

"Kushina, you know that with my ninjutsu talent, I probably don't have the energy to learn these things."

"Give it a try. Maybe you have a great talent for sealing techniques, just like me! There are so many scrolls here, there should be one that suits you, right?" Kushina advised.

"This..." Bai Yu hadn't considered these scrolls before mainly because he didn't want to arouse the Third Hokage's suspicion, since his persona was primarily focused on medical ninjutsu.

Kushina did not hide the fact that she had inherited the Uzumaki clan's legacy from Shiro, and she had previously taught Shiro how to create shadow clones.

However, after being reminded by the Third Hokage, Kushina stopped teaching Shiraha anything else.

As for Bai Yu, considering his average chakra talent, he mainly focused on breathing techniques and meditation, and did not take the initiative to mention this matter to Kushina again.

He felt he didn't have enough time to practice meditation, spells, and potions, let alone ninjutsu and sealing techniques.

"Let me take a look first." Bai Yu sat down on the ground and began to examine the scrolls in the box.

Most of the ninjutsu and sealing techniques in it are above B-rank.

Among them are many A-level and even S-level super-powerful sealing techniques.

Three-way Seal, Four-Element Seal, Inner Four-Element Seal, Contract Seal, Yin Seal, Four Red Yang Formation...

Besides some seals that ordinary people can use, there are also many special seals that require the bloodlines of Senju and Uzumaki to use.

"This is... magic! What is magic?"

Bai Yu stared at the golden scroll in his hand, his pupils constricting.

[Chapter 37. Natural Energy and Meditation]

The scroll contains a powerful sealing technique called "Myojinmon," a sage technique capable of suppressing tailed beasts.

The person whose name is marked is Hashirama Senju, the First Hokage.

Bai Yu learned about the concept of "immortal arts" for the first time.

"Sage Arts are Sage Arts, a very magical power." Kushina tried to explain, but with her not-so-bright mind, she was obviously not particularly suited to teaching, and besides, she had only heard of Sage Arts.

Bai Yu had no choice but to search for the relevant scrolls himself, and he read through all the scrolls containing records of immortal techniques.

Finally, he obtained some useful information—

By absorbing a certain amount of natural energy and then combining it with spiritual and physical energy in a certain proportion, the human body can refine a kind of "Sage Chakra" whose quality completely surpasses that of ordinary chakra.

This state, in which natural energy can be used, is known as "Sage Mode".

In Sage Mode, techniques released using "Sage Chakra" are called "Sage Techniques".

This state allows one to utilize natural energy to enhance both attack and defense.

"Sage Chakra" can enhance the power of one's ninjutsu, taijutsu, and genjutsu by several times, tens of times, or even dozens of times.

The same ninjutsu, when used in this state, has a completely different power. In order to distinguish it from ninjutsu, it is called "Sage Technique".

In the current ninja world, only the three sacred sites of Sage Mode—Mount Myoboku, Ryuchi Cave, and Shikkotsu Forest—possess complete Sage Mode lineages.

Hashirama Senju learned his Sage Mode from Shikkotsu Forest.

"Sage Mode...absorbing natural energy...I never expected that the Naruto world would have a training method that allows one to use external forces. It seems I underestimated the power system of this world."

Bai Yu put down the scroll and fell into deep thought.

The reason he subconsciously believed that the ninja's chakra system was inferior to the wizard's magic system was primarily due to the difference in quality between the two.

Chakra is a product of the combination of spiritual energy and physical energy.
