Naruto's opening, a black ball beast

Konoha 44th May!

At Training Ground No. 34, under a cloudless sky, Inuzuka Tsutomu and Matt Dai were lying on the ground attentively, studying the breathing rhythm of the frog.

Since the two teams graduated from the ninja school a few months ago, he probably knew that he could not guide these ninjas who came from a secretarial family. Except for the daily tasks, Sawada was wise enough not to disturb Inuzuka.

This also gave Inuzuka plenty of free time. Apart from necessary tasks, during this time he continued to immerse himself in his practice as usual.

In addition to the necessary daily practice, he and Matt Dai studied the development of internal boxing.

After more than a year of unremitting study, and with Matt Dai's rich experience, the method of external refining of internal boxing has barely taken shape, but now the two of them are stuck on the most critical step from the outside to the inside.

Because they had never had any experience involving internal organs training, they were stumped by how to effectively exercise internal organs with dark energy.

And because the internal organs were too fragile, the two of them did not dare to try the step from outside to inside for a long time.

You must know that internal injuries do not require external injuries. External injuries can be easily cured. If there is a problem with the internal organs, even if you have magical energy like chakra, you will lose your life if you are not careful.

During this time, Inuzuka Tsutomu has been thinking about where is the best place to start.

After discussions between him and Matt Dai, they agreed that if you want to develop an internal training method to exercise the internal organs, you must have professional guidance from specialized medical ninjas.

After all, when it comes to understanding human organs, probably no one is more familiar with them than professional medical ninjas.

When it comes to medical ninjutsu, I'm afraid no one is better than Tsunade, but the two of them can't get along with Tsunade, and in Inuzuka's opinion, Tsunade's current state is also a big one. question.

In addition to Tsunade, there is another suitable candidate, and that is Orochimaru.

And with Anko as the matchmaker, it is obviously much easier to hook up with Orochimaru than to get close to him. However, Orochimaru is too dangerous now. If he has a choice, Inuzuka Tsutomu really doesn't want to be related to that kind of guy now.

"卆, accept my challenge! This time, I will definitely defeat you..."

While Inuzuka was thinking about how to solve the lack of medical knowledge, a familiar shout suddenly sounded from a distance.

"卆, your partner is here to find you, I won't interrupt you to reminisce about old times, come on!"

"Then you go and do your work first, Uncle Dai."

After saying hello to Matt Dai, Inuzuka raised his head and stared at the passionate Obito with a bored expression. When Obito saw the little kid following Obito, his expression was subconsciously startled.

"Who is this?..."

"This one is my cousin. His name is Uchiha Shisui. Unlike me, he is a real genius."

"Hello, senior, I am Shisui Uchiha. Brother Obito often mentions you and says you are a genius ninja like Kakashi-senpai."

Facing Inuzuka's slightly surprised gaze, the little kid had a gentle face and his words were full of humility.

"Shisui..."

Looking at Uchiha Shisui in front of him, Inuzuka Tsutomu was indeed surprised.

The two brothers don't look like members of the Uchiha clan. If Obito is impulsive and reckless, Shisui is more like a gentle boy next door.

No matter what it is, he is completely different from the Uchiha clan who are arrogant in their bones and tend to be indifferent. It is no wonder that they are not welcomed by the clan.

Shisui is better, gentle and sincere, and a well-deserved genius. In the Uchiha clan's concept of respecting the strong, he can naturally be somewhat tolerated.

But Obito is miserable. Although he has great potential, his unconventional character and often ridiculous behavior are regarded as a shame by the Uchiha clan.

It's no wonder that this guy later turned evil and showed no mercy to Uchiha. Maybe among the entire Uchiha clan, only an alternative like Shisui could get along with him.

"Hey! Shisui, you guy, when did I say such a thing..."

"Didn't Brother Obito say that? Senpai-senpai is another person who is about to surpass you after you defeat Kakashi."

"Hmph~ It's not that I'm about to surpass him, but I'm going to beat this guy up soon..."

"卆...you should wake up! In the past two months, after Minato-sensei's guidance, I have become a different person."

After complaining to Uchiha Shisui for a while, Obito finally realized that he was here to challenge Inuzuka.

"Really? If you didn't tell me, I would have forgotten that your mentor is Minato Namikaze... Then let me see how much progress you have made in the past two months. Can you give me the power to defeat me? illusion."

Facing Uchiha Obito's confident look, Inuzuka Tsutomu couldn't help but become slightly interested.

Others don't know it, but he is very aware of Obito's potential. After rigorous training, maybe Obito can bring some pressure to him.

Speaking of which, since the development of Neijiaquan, he has never fought anyone other than Matt Dai and his son.

"Hmph~ If it's an illusion, you'll know soon."

"Take the move! Swish swish..."

Looking at Inuzuka with a scornful expression on his face, Obito's figure was like a gust of wind, and the shuriken in his hand was merciless, heading straight for Inuzuka's vital point.

"Snapped..."

"It's true that we have made great progress, Obito, but these are far from enough..."

Under Obito's tiger-like attack, Inuzuka looked at six directions and raised his hands and feet lightly. It seemed that his movements were extremely slow and concise, but he could accurately predict Obito Uchiha's offensive every time, just like It is common to predict in advance.

"What a superb physical skill!"

Uchiha Shisui on the side was also dazzled by what he saw at this time. Except that Obito, who usually behaved extremely recklessly, was able to perform such a fierce attack, he was surprised.

Inuzuka's special taijutsu was not only refreshing to him, but the simple movements that seemed to be light and heavy shocked him greatly. He couldn't help but put himself into Obito's position in order to find a way to solve it.

"Damn it!"

"Art fire escape ho fireball!"

Faced with the situation of being unable to attack for a long time, Obito's mentality gradually became anxious. Taking advantage of the moment when his body was wrong, his cheeks bulged high, and the huge wave of fire instantly drowned Inuzuka's figure.

"Obito, you're doing your old habits again!"

"Excessive consumption of chakra will seriously consume your physical strength and expose flaws in your offensive."

While Obito was looking around, Inuzuka Tsumugi's figure appeared silently behind him at some point, and his hand gently rested on his shoulder.

"when."

The moment Inuzuka's voice sounded, Obito immediately became vigilant, but just when he wanted to escape, his body suddenly became weak, and all the strength in his body seemed to be drained away in an instant, and he staggered and collapsed to the ground.
