Chapter 852: Teaching in the Hidden Leaf, the System Says I

Kitazawa glances at her but doesn't say anything.

He locks the door and heads to the adjacent Hokage building.

It is already lunchtime.

Usually, he eats with Sasuke Uchiha and the others at school, but since he happens to be at the Anbu base today, he goes to the Hokage building to eat.

With so many departments and institutions in the Hokage building, there is naturally a cafeteria.

Kitazawa hasn't eaten there yet, so he can try it today.

But eating in the cafeteria is boring; he has to find Tsunade to eat with, and he can also feast his eyes.

Kitazawa raises his hand and knocks on the door.

He is not Tsunade; he is not used to kicking doors.

"Come in."

Tsunade's voice rings out.

Kitazawa pushes the door open and walks in.

Tsunade and Shizune are sitting on the sofa eating.

The food is placed on the coffee table.

"Can I join Itachi?"

Kitazawa blinks and asks.

"Of course Itachi can."

Shizune smiles and asks again, "Who do Itachi want to sit next to?"

She and Tsunade are sitting face-to-face, each on one side.

"It's the same wherever I sit."

Kitazawa walks up and sits next to Tsunade.

"Why are Itachi eating with us today?"

Tsunade leans forward slightly, picking up a piece of fried shrimp with her chopsticks.

Kitazawa's gaze subconsciously falls on her.

Her waist and back form a straight line, and due to gravity, her clothes sway twice.

Tsunade takes a bite of the fried shrimp, raises an eyebrow, and directly lifts her leg, stepping on Kitazawa's foot.

"There's no special reason."

Kitazawa retracts his gaze and says, "I just suddenly wanted to try the food made by the Hokage building cafeteria."

"I feel it's quite a bit worse than what Itachi make."

Shizune says very flatteringly.

"Thank Itachi."

Kitazawa places the food he packed from the cafeteria on the coffee table.

He picks up his chopsticks and picks up a piece of meat.

How should he put it?

The taste is okay, not terrible, but it can't be called particularly delicious either; it can only be said to be acceptable.

"I have improved the limb regeneration medical ninjutsu."

Kitazawa suddenly thinks of something and says.

"What did Itachi improve?"

Shizune asks curiously, "I think limb regeneration is already quite perfect; did Itachi reduce the side effects?"

"Can it regenerate organs with Kekkei Genkai?"

Tsunade thinks of the time Fugaku Uchiha asked Kitazawa to improve limb regeneration.

"No."

Kitazawa shakes his head and says, "What I improved is allowing limb regeneration to be used on oneself."

Actually, what he is talking about is the Forbidden Medical Jutsu: Physical Regeneration.

"Eh?"

Shizune looks surprised and asks, "Then what if an arm is broken?"

"It can also be regenerated."

Kitazawa says with a smile on his face.

"Can it be used in battle?"

Tsunade narrows her eyes and asks.

"It can be used."

Kitazawa nods and says.

"Are Itachi sure?"

Upon hearing this, Tsunade's expression tightens, and her tone becomes serious.

If it can be used in battle, the value of this medical ninjutsu will be multiplied.

Especially in evenly matched battles.

After finally causing fatal damage like a broken arm or leg, the enemy regenerates it on the spot with a medical ninjutsu; it would make the enemy break down.

"Why would I lie to Itachi?"

Kitazawa takes out the scroll for the Forbidden Medical Jutsu: Physical Regeneration and hands it to her.

Tsunade immediately puts down her bowl and chopsticks to look at it.

Shizune stands up and leans over.

As a medical ninja, she naturally understands the significance of this medical ninjutsu very well.

Kitazawa continues to eat in a leisurely manner.

Given the difficulty of the Forbidden Medical Jutsu: Physical Regeneration, Tsunade is probably the only one in the Hidden Leaf Village who can learn it.

In fact, he gave it to Tsunade for a simple purpose: to increase her strength.

She has the Yin Seal, so she is already very hard to kill; now, with the addition of the Forbidden Medical Jutsu: Physical Regeneration, she is truly an immortal body in a certain sense.

Of course, just having strong recovery power is not enough.

After all, one cannot just take hits.

Tsunade's attack methods are relatively simple, only having Super Strength.

Kitazawa is already modifying another of Shennong's forbidden medical jutsus, which is Physical Activation.

His goal is to modify it into a Yang Release Chakra Mode similar to the Lightning Release Chakra Mode.

By then, whether it is him or Tsunade, both can use it.

He can also complete a system task along the way.

However, the difficulty of modification is relatively high and will take some time.

"This is truly... incredible!"

Shizune says in a daze after finishing it.

This is no longer a simple modification, but the creation of a brand-new medical ninjutsu.

Compared to limb regeneration, the Forbidden Medical Jutsu: Physical Regeneration is even more powerful; even if the body is torn apart, it can be reorganized and restored.

"Itachi are the second ninja I have ever seen with extremely high talent in creating ninjutsu."

Tsunade closes the ninjutsu scroll and says in a deep voice.

The first ninja is naturally Tobirama Senju.

He created a large number of ninjutsu for the Hidden Leaf Village, including quite a few forbidden jutsus with astonishing effects.

"If limb regeneration is an S-rank medical ninjutsu, then this physical regeneration is an S-rank forbidden medical jutsu."

Tsunade says thoughtfully, "Its difficulty and side effects are both higher."

"But the effect is also better."

Shizune sits back on the sofa, "The most important thing is that it can be used in battle."

When it really comes to a life-or-death moment, one certainly won't care about any side effects.

"That's true."

Tsunade nods and looks at Kitazawa.

There is no doubt that his medical ninja talent is very high.

But previously, she thought that Kitazawa was at most about the same as her in terms of medical ninjutsu, but now she has changed her mind.

Just these two medical jutsus are enough to leave a heavy mark on the history of medical ninjas.

Creating one or two more medical jutsus in the future, surpassing her in strength and fame will not be a problem.

"Why are Itachi staring at me in a daze?"

Kitazawa raises his hand and waves it in front of her.

"I'm thinking about what reward to give Itachi."

Tsunade puts away the ninjutsu scroll and says.

Although not many people can learn the Forbidden Medical Jutsu: Physical Regeneration, its effect is self-evident.

Such an S-rank forbidden medical jutsu naturally must be given a correspondingly generous reward.

"Owe it to me for now."

Kitazawa's gaze falls on her rosy lips.

Tsunade immediately glares at him.

She turns her head to look at the food on the coffee table, bites her lip, and the emotions in her heart are somewhat inexplicable.

Thinking about it carefully, the reason Kitazawa brought out the Forbidden Medical Jutsu: Physical Regeneration is most likely because of her.

Because for now, she is probably the only one who can learn it.

"Eat."

Tsunade quickly returns to calm.

After lunch, Kitazawa finds another place to practice the Yin Seal.

Of course, practicing the Yin Seal is just what he tells Tsunade; in reality, he is practicing the Five Elements: Great Super-Bomb Technique.

Time passes in the blink of an eye for another week.

This week, Kitazawa has very few things to do.

Besides training, it is just refining and adjusting medicine.

There is nothing major in the Hidden Leaf Village, only the negotiations between Shikamaru Nara and the others and the Hidden Mist Village are still continuing, arguing non-stop.

But after talking for so long, it is also coming to an end.

Monday.

Kitazawa gives Konan a day off.

She takes the medicine back to the Akatsuki.

Although it is a half-month supply of medicine, she will not stay long; she will return to the Hidden Leaf Village after delivering the medicine.

Kitazawa arrives at the Ninja Academy.

Two weeks have passed since the last monthly exam, and he needs to prepare for the next one.
