Legitimate Beating of Qingyu?

After days of repeated development and practice, this technique had finally taken initial shape just moments ago. However, to perfect it completely, further testing was required. "Kawaki Aoba, you've come at the perfect time. Could you accompany your teacher and test whether the final refinement of this technique is a success?"

Yuhi Shinku's eyes revealed a look of sincerity, and the smile on his face was exceptionally kind.

But to Kawaki Aoba, this expression was enough to send a chill down his spine.

Holding onto his suspicions, Kawaki Aoba observed Yuhi Shinku's face closely, and in the end, he truly managed to discern a hint of the truth.

Although Teacher Shinku was smiling, he was plotting against him in his heart. This was how Kawaki Aoba interpreted it:

This brat's strength is growing too fast. If I don't take this chance to teach him a good lesson now, I'm afraid I won't have another opportunity later.

Kawaki Aoba knew that Yuhi Shinku had made up his mind; he was determined to give him a sound beating today.

Since there was no avoiding it, Kawaki Aoba decided to just go for it. It would be the perfect chance to test the strength of Teacher Shinku's chakra cloak using the Water Stream Rock Smashing Fist.

"Since Teacher Shinku has already said as much, as your student, I must certainly do my part." Kawaki Aoba agreed to the spar.

Fumbling through his ninja tool pouch, Kawaki Aoba pulled out two blue potions—one large and one medium.

He handed the large one to Yuhi Shinku, while the medium blue potion would be saved for himself to drink one minute later, once the other had finished manifesting his chakra cloak.

For Kawaki Aoba's current small frame, the medium blue potion was more than enough.

Once the minute had passed and Yuhi Shinku had stabilized his chakra cloak, the spar between teacher and student officially began.

The first to strike was Yuhi Shinku. He had been finding Kawaki Aoba an eyesore for quite some time; although he had accepted the fact that this brat would eventually become his son-in-law, he just felt inexplicably annoyed.

In particular, this was likely the last chance he would have to beat the boy up in a justified manner. Yuhi Shinku took this very seriously and was determined to use his full strength.

Perhaps this was the "doting" of a father-in-law toward his son-in-law.

With the chakra cloak covering his body, Yuhi Shinku's speed was indeed much faster than usual. Fortunately, Kawaki Aoba was using Observation Haki to track his target; otherwise, even with his former Byakugan, it would have been difficult to catch a glimpse of Teacher Shinku's figure.

A powerful, high-speed whip kick came from the side. The speed and force far exceeded Yuhi Shinku's usual level. Kawaki Aoba's eyelids twitched wildly—had this been before he mastered the Water Stream Rock Smashing Fist, he definitely would have been sent flying by that kick.

Teacher Shinku knows I drank the potion beforehand, so he's planning to beat me to a pulp as long as I don't die, he thought.

Kawaki Aoba didn't dare to be careless. He twisted his waist and stood his arm up at his side, while at the same time, a deep blue water-attribute chakra covered his entire arm.

The raw physical constitution of people in the ninja world could not compare to the martial arts masters in One Punch Man, but compared to pure fist techniques, a ninja's advantage lay in the ability to augment them with chakra.

In particular, the water-attribute chakra was perfectly compatible with the Water Stream Rock Smashing Fist. Used in combination, the power was significantly greater than the fist technique alone.

However, this wasn't something Kawaki Aoba had pondered out; it was purely an instinct of his body after obtaining the Water Stream Rock Smashing Fist.

Bang!

Yuhi Shinku's whip kick arrived, slamming heavily into Kawaki Aoba's chakra-coated right arm.

There was no sound of bone breaking as expected, but Kawaki Aoba hadn't completely blocked it either.

After the force of Yuhi Shinku's kick, Kawaki Aoba lost his balance, spinning in a large circle of over 180 degrees on the spot.

The trajectory of his swinging arms resembled flowing water, parting the air and stirring up ripples.

Wait!

Watching Kawaki Aoba's movements, Yuhi Shinku noticed something unusual.

It wasn't until Kawaki Aoba's right fist, radiating blue chakra, had completed its rotation and was about to strike him that he truly understood.

Thud!

The same force, the same counterattack. The difference was that, compared to Yuhi Shinku's pure taijutsu, Kawaki Aoba's punch carried a penetrating chakra attack. The blue water-attribute chakra had actually pierced directly through the chakra cloak he had manifested.

It was somewhat like the Hyuga Clan's Gentle Fist, yet entirely different. At the very least, the destructive power of a single strike from the Gentle Fist would never reach this level.

After quickly putting some distance between them, Yuhi Shinku looked solemnly at the sleeve of his left arm, which had been ruined by Kawaki Aoba's attack.

To be honest, if Yuhi Shinku had wanted to dodge earlier, Kawaki Aoba's punch would never have hit him.

As for just now, it was merely the teacher in him wanting to test the new skill his student had brought out.

But after experiencing it firsthand, Yuhi Shinku felt incredibly frustrated.

Why was it that his own student could always produce ninjutsu and taijutsu that he couldn't understand, yet possessed such extraordinary effects?

Especially this fist technique—it clearly hadn't existed when they were on missions before.

Could it be that he had just developed it? But hadn't he been learning the Darkness Technique from the Hokage's people these past few days?

Even for a monster of a genius, there had to be a limit.

"Aoba, what kind of fist technique is this? I've never seen you use it before." While cloaked in chakra and attacking Kawaki Aoba with taijutsu, Yuhi Shinku didn't forget to ask.

Kawaki Aoba could see from his ease that Teacher Shinku wasn't using his full strength.

Looking at Kawaki Aoba, he was also using the newly acquired Water Stream Rock Smashing Fist to handle Yuhi Shinku's offensive. Although there was a significant gap in strength between them, Kawaki Aoba was able to manage by utilizing all his various taijutsu skills.

Finding a gap where the pressure was low, Kawaki Aoba took the opportunity to respond: "Teacher Shinku, are you asking about the fist technique I'm using now? Of course, I created it myself. However, it does have some relation to the Hyuga Clan. Once I've perfected the chakra cloak, I'll discuss it with you in detail."

What a brat!

Yuhi Shinku cursed inwardly. He stopped speaking and began to exert his full strength in taijutsu; he wanted to see exactly how much substance this self-created fist technique really had.

Although Kawaki Aoba could create many hand-signless ninjutsu and taijutsu like Shave and Finger Pistol, those were all straightforward, direct attacks. A systematic discipline like a fist technique was entirely different. As for Kawaki Aoba being able to create a complete set of fist techniques, Yuhi Shinku would never believe it, even if he died.
