Black Coffin and Water Stream Rock Smashing Fist

As Kawaki Aoba integrated the skill orb into his body, he mastered the abilities contained within it in an instant.

High-level Kido, Hado #90: Black Coffin.

Once activated, Black Coffin forms a massive cube resembling a black coffin, trapping the target inside to suffer the torment of a thousand blades.

As a high-level Kido, the damage ceiling of Black Coffin is quite high. In the hands of Aizen, even a Black Coffin cast without an incantation—possessing less than a third of its original power—could instantly kill a captain-level Soul Reaper.

In the ninja world, provided he found an opening, it might not easily one-shot someone at the level of the Five Kage, but it would certainly be more than enough to deal with an average Jonin.

Of course, the damage potential of Black Coffin comes at the cost of massive consumption.

In the world of Bleach, to release a high-level Kido like Black Coffin, one's spiritual pressure must at least reach the level of a captain or lieutenant.

For Kawaki Aoba in the ninja world, the only way to pull off a Black Coffin is by cheating.

After fully digesting the Black Coffin skill, Kawaki Aoba suddenly felt a wave of gratitude toward his teacher, Yuhi Shinku.

If not for the Chakra Cloak that Yuhi Shinku had just successfully developed, Kawaki Aoba wouldn't even dream of using a skill like Black Coffin anytime soon.

Even with a massive chakra potion, it wouldn't be enough. No matter how terrifying its chakra recovery rate might be, there is ultimately a limit to the total amount of chakra his body can contain, and any chakra that leaks out is completely wasted.

But with the Chakra Cloak acting as an external battery to store that leaking chakra, didn't he now have the energy required to cast Black Coffin?

Therefore, this time, Teacher Shinku is the GOAT.

Suppressing his excitement, Kawaki Aoba decided to quickly sacrifice the Gentle Fist manual sponsored by the Hyuga Clan, then head straight to Teacher Shinku to learn the Chakra Cloak technique.

Once he did that, the damage ceiling he could output would definitely reach the pinnacle of the current ninja world.

By then, he wouldn't need to worry about the impending Third Shinobi World War or the threat from the Hyuga Clan; absolute strength would be enough to crush any of their conspiracies.

With a heart full of excitement, Kawaki Aoba placed the Gentle Fist manual from his memory onto the Sacrificial Altar in the form of a memory orb.

Soon, the Sacrificial Altar emitted a glow, and the sacrifice began.

The light dissipated, and the sacrifice ended.

Just like when he obtained Black Coffin, the reward this time was also a skill orb.

However, this orb was pale blue, with what looked like water flowing irregularly inside it.

"Huh." Kawaki Aoba let out a sound of surprise, feeling quite unexpected; the Gentle Fist manual, for which he had held little hope from the start, had actually yielded a result.

Initially, the reason Kawaki Aoba didn't think the Gentle Fist manual would yield anything good wasn't because he held any prejudice against the Gentle Fist.

It was purely because the Hyuga Clan was too stingy; even while plotting against him, they hadn't provided a complete Gentle Fist manual.

High-level applications of the Gentle Fist, such as Eight Trigrams Vacuum Palm or Eight Trigrams Palms Revolving Heaven, weren't even mentioned in this manual.

Now that it could be exchanged for a skill orb that looked quite decent, how could Kawaki Aoba not feel surprised by such luck?

Without hesitation, Kawaki Aoba integrated the blue skill orb into his body.

As the skill merged with him, a wealth of knowledge regarding fist techniques and insights flooded his mind.

"Water Stream Rock Smashing Fist," Kawaki Aoba murmured the name of the newly acquired technique.

This was the signature move of Silver Fang Bang, the third-ranked S-class hero in One Punch Man.

The power of this fist technique goes without saying; once mastered, taking down a Kage-level ninja shouldn't be a problem.

Even now, the boost to Kawaki Aoba's personal combat power was significant.

With this set of techniques, even without drinking potions, Kawaki Aoba was confident in facing a Chunin head-on. Once he started cheating, the power unleashed in combination with Shave and Finger Pistol from the Six Powers would only be greater.

It is worth noting that the compatibility of Water Stream Rock Smashing Fist is quite high, and due to its inherent characteristics, even if he forcibly changed moves mid-battle, it wouldn't cause damage to his body like the Six Powers might.

Beyond that, what Kawaki Aoba valued most about Water Stream Rock Smashing Fist was its ability to strengthen the physique.

On this point alone, it was far superior to the Hard Fist or Gentle Fist styles found in the ninja world.

However, the Water Stream Rock Smashing Fist that Kawaki Aoba obtained did have some minor flaws.

Perhaps because the sacrificed Gentle Fist manual was incomplete, the Water Stream Rock Smashing Fist he received lacked the subsequent, high-powered Exploding Heart Release Fist and Cross Fang Dragon Slayer Fist.

Although those two ultimate moves were combo techniques combining Water Stream Rock Smashing Fist and Whirlwind Iron Cutting Fist, what Kawaki Aoba valued most was the principle behind how those two styles combined.

If he could understand the principle of that joint attack...

To have such thoughts, one could only say that Kawaki Aoba was being a bit greedy.

But that was the normal reaction for any person.

Carrying that tiny bit of regret, Kawaki Aoba left his home and headed straight for the Yuhi Residence.

What could be more joyful than gaining two ultimate techniques? Gaining three.

As for the Hyuga Clan monitor following him, Kawaki Aoba wasn't worried at all that the other party would discover the secret of his potions.

The location of the Yuhi Residence wasn't as remote as his own home; it could even be considered the heart of the civilian residential area.

Kawaki Aoba knew of at least seven or eight Jonin living on that very street.

If a ninja from the Hyuga Clan dared to activate their Byakugan there, the consequences... tsk tsk tsk.

"Aoba, you've come at just the right time. I was just thinking of having Kurenai call you over."

At the Yuhi Residence, upon seeing Kawaki Aoba, Yuhi Shinku appeared very excited and happy.

Presumably, after completing the Chakra Cloak, Yuhi Shinku couldn't help but want to show it off to his student, proving that he, as a teacher, was not lacking in talent either.

After all, with a monster of a student like Kawaki Aoba, who possessed such prodigious talent in developing ninjutsu and taijutsu, the pressure on Yuhi Shinku was immense.

Kawaki Aoba, who had come specifically to seek guidance from his teacher, naturally wouldn't undermine him; instead, he played the part of a perfect straight man.

"Teacher Shinku, you look so happy. Could it be that something joyous has happened?"

This remark from Kawaki Aoba hit the nail right on the head, striking the very source of Yuhi Shinku's excitement.

With a look of smug satisfaction on his face, he laughed and said, "Indeed, something good has happened! Aoba, do you remember that technique you mentioned a few days ago? The one that repurposes the chakra dissipated after consuming medicinal agents?"
