Fūinjutsu and Medical Ninjutsu!

Asuma had no time to check his achievement reward, because the Wind Style: Rasenshuriken he had thrown began to rapidly expand after flying only twenty meters.

Retreating to Tsunade and the Shadow Clone's side, Asuma immediately shouted, "Tsunade, be careful! The storm is coming!"

But Tsunade was already staring in shock at the rapidly expanding sphere of light. In the blink of an eye, it had grown to over fifty meters in diameter, and within her senses, its area of coverage contained an extremely terrifying and dense Wind Release Chakra reaction.

In other words, this ninjutsu was not as simple as a single-target technique.

If it hit someone, escape would basically be impossible.

Other than the Reverse Summoning Technique or spatial ninjutsu like the Flying Thunder God, no Body Flicker Technique or Substitution Technique could evade this technique.

Boom!

A wild gale swept through, sending sand and stones flying.

Asuma and Tsunade hurriedly raised their hands to shield their eyes. In the next instant, the gale engulfed them, blowing their hair straight back.

If they had not applied Chakra beneath their feet, they would have been blown away and swept off their feet.

After quite a while, the storm passed.

Tsunade flickered over to the edge of the massive crater.

Looking out, she saw a giant pit more than fifty meters wide and twenty to thirty meters deep.

Water was already beginning to seep up from the bottom.

"What an astonishing Wind Style ninjutsu!"

Tsunade said in shock, "This should be the strongest Wind Style ninjutsu in the ninja world. At the very least, I've never seen anything with greater attack power!"

Asuma had already dispelled his Shadow Clone and come to Tsunade's side. He was also quite satisfied as he smiled. "I finally have a trump card of my own!"

Given the current state of the ninja world.

If Uchiha Madara did not appear and Nagato did not suddenly power up, the Third Tsuchikage and the Third Raikage were among those who could withstand this move head-on.

The Fourth Raikage might not be able to withstand it yet.

On Konoha's side, only his father, Namikaze Minato, and Uzumaki Kushina could probably block it.

If Jiraiya had not learned the Rasengan and did not have Sage Mode, he likely would not be able to block it either.

Of course.

That was assuming it hit.

A ninjutsu had to hit to be lethal. Otherwise, it was useless!

Why was Fire Style said to never kill anyone? Because it often could not hit its target.

After recovering from her shock, Tsunade turned to Asuma and looked at him as though he were a monster. Then she solemnly advised, "Your technique is extremely powerful, but unless you are absolutely certain before throwing it, or the distance is great enough, you'd better use it sparingly!"

"I understand, Tsunade!"

Asuma readily accepted her advice.

Since he had already thrown it, that meant the technique was now perfect. Given enough time, he would naturally be able to throw it farther.

Next, it was simply a matter of time.

His Experience Points would soar!

"Let's go back. With your Chakra Control, you're qualified to learn the Yin Seal, and you're also well suited for Medical Ninjutsu!"

As Tsunade spoke, she had already vanished.

Senju Ancestral Home.

Tsunade brought out a large number of books and scrolls on the basics of Fūinjutsu and Medical Ninjutsu, piling them in front of Asuma.

They were like two small mountains.

Asuma's eyes lit up as he looked at them.

Sarutobi Hiruzen was known as the Ninjutsu Doctor and was proficient in all kinds of ninjutsu, including Fūinjutsu.

But the Sarutobi Clan's materials on Fūinjutsu and Medical Ninjutsu definitely could not compare to what Tsunade had here.

Of course, the Hokage Building had a special archive, with secrecy levels second only to the Scroll of Seals. There were many materials there as well.

However, its records on Medical Ninjutsu probably still could not compare to Tsunade's.

"They're all Experience Points!"

Asuma was brimming with enthusiasm.

Tsunade watched from the side, her expression turning strange.

It was her first time seeing someone like this.

Over the next few days, aside from his basic training, Asuma even temporarily set aside his practice of the Wind Style: Rasenshuriken and devoted most of his energy to studying Fūinjutsu and Medical Ninjutsu.

For both fields, a foundation of theoretical knowledge was even more important than with other ninja arts.

As a result, his dates with Kurenai amounted to only a short hour each evening.

However, with Tsunade's guidance and the ability to seek advice from his father, the Third Hokage, at the Hokage Building, Asuma improved rapidly.

The rapid rise of his Experience Points and Intelligence Stat also kept Asuma engrossed, to the point where he wished he did not need to sleep at night.

Of course, while his original body slept, his Shadow Clone continued studying.

After three consecutive days, Asuma was visibly exhausted.

Tsunade frowned when she saw him. "Asuma, you're still young. You don't need to be in such a hurry."

"Take the day off today!"

Asuma paused, rubbed his temples, then nodded. "All right!"

He was indeed too mentally exhausted, and his learning efficiency had dropped.

After leaving the Senju Ancestral Home, Asuma rubbed his face as he opened the system and headed toward the Hot Spring District.

A soak in a hot spring would feel great.

He had been so busy these past few days that he had not even claimed the reward for his previous achievement of creating an S-rank ninjutsu without hand seals at the age of nine.

When he opened the Skill Pack, he found the Level 4 Wind Body Flicker Technique.

"This technique is pretty good. It's exactly what I need!"

Asuma was delighted.

He had already been planning to train in a Wind Style Body Flicker Technique.

The Body Flicker Technique he had used before belonged to taijutsu.

Through explosive bursts of strength and skill, sometimes supplemented by bursts of Chakra, it allowed his speed to increase sharply in an instant.

There were also plenty of ninjutsu-based Body Flicker Techniques, such as Uchiha Shisui's Water Body Flicker and Haku's Wind Body Flicker in the future.

Asuma's attainments in taijutsu were far inferior to his Wind Release Chakra Nature Transformation. With Level 10 Chakra Control as well, improving his Wind Body Flicker would undoubtedly be much faster than improving a taijutsu-based Body Flicker Technique.

"Now that I have Wind Body Flicker, I still need a Sensory Ninjutsu!"

With that thought, Asuma used the Wind Body Flicker he had just acquired to speed up his trip to the Hot Spring District.

He traveled while familiarizing himself with Wind Body Flicker, killing two birds with one stone.

Half an hour later.

Asuma emerged from the hot spring house feeling refreshed.

Strolling through the Hot Spring District and watching the young women of all sorts of figures pass by, Asuma relaxed for once.

"Once the Third Great Ninja War ends, maybe I should find a job at the Ninja Academy?"

Who did not want an easy life?

Unfortunately, the Scythe of Death still hung over his head, and Asuma did not dare slack off for even a single day.

"Huh?"

Suddenly, Asuma stopped in his tracks, his gaze landing on the roof of a hot spring house.

"Jiraiya!"

Asuma's eyes lit up, and he immediately transformed into a gust of wind and arrived on the roof.

"Senior Brother Jiraiya!"

Asuma appeared.

Jiraiya, who had been utterly absorbed and wore a perverted expression, stiffened. He slowly turned his head, and upon seeing Asuma, immediately sighed in relief. In a quiet but righteous tone, he said, "Asuma, I'm gathering material right now!"

"Gathering material?"

"Let me see!"

Asuma squeezed his head over.

Gasp!

"It really is a fine view!"

Asuma was unwilling to look away.

Jiraiya was stunned at first, then smiled like he had found a kindred spirit. "Right? Right? This is excellent material!"

The two chattered away, passing judgment and offering critiques.
