Demon Slayer: Muzan, will you dance too?

Extreme burst and sustained burst are completely different optimization directions. In the battle against Upper Moon Five Gyokko, Kiyokawa Izumi exposed a lot of problems.

Perhaps because this body is not yet an adult and is still in the developmental stage, its speed, strength, and endurance are not particularly outstanding.

There is still a lot of room for improvement in the basic values; they have not yet reached the theoretical limit.

The worst aspect is endurance!

The combined usage time of the Third Form and the Fourth Form did not even exceed five minutes.

At his peak, Kiyokawa Izumi might be able to easily defeat a Lower Moon, but against any Upper Moon, even the lowest-ranking Upper Moon, Gyutaro, he wouldn't be able to win quickly.

His peak performance isn't enough to break the deadlock; he might be able to suppress the opponent, but barring any unforeseen circumstances, his form will decline rapidly.

Then, they will naturally be eliminated.

Once he gets bogged down in a tug-of-war or a war of attrition, he is bound to lose.

Both the Third Form and the Fourth Form are extremely taxing on physical strength.

If his combat strength is 10 under normal conditions, then theoretically his strongest value is 30.

After switching breathing techniques, because his swordsmanship level was already quite high, coupled with a significant increase in his base stats, even a casual strike could generate a combat power of thirty-five or even forty.

Kiyokawa Izumi was also hesitant about whether to abandon Anko.

The Seven-Day Breathing Method has a huge and obvious effect on improving bodily functions. However, it will certainly not be perfect for first-time users, especially if they have injuries.

Focusing on the seven-day breathing method may still not solve the problem of insufficient endurance, but in a short period of time, one's strength will be significantly enhanced.

The trade-off is that the upper limit is locked to some extent.

He is, after all, just a user, and may not even be able to instantly increase his lung capacity to four times the normal level, let alone continue to develop it along the original concept.

Six times, eight times, or even ten times—it sounds tempting, but he can't do it.

Once he reaches a certain limit, his strength will be fixed for a long period of time in the future.

If you want to upgrade further, you can only consider the three-piece set.

Needless to say, the unlocking conditions for the markings have never been clear – is it that the body temperature is not high enough, the heart rate is not fast enough, or the willpower is not strong enough?

Kiyokawa Izumi may not be the first swordsman of this era to unlock the markings, ultimately because the unlocking conditions are too vague.

As for Tongtou and Hedao, they were making things difficult for him, an ordinary person with little talent.

Once Kiyokawa Izumi abandons his original breathing method, he will be stuck in a bottleneck period for a long time to come.

The same applies to swordsmanship levels.

Level five seems to be the limit for ordinary people.

Looking at ourselves, we realize that we are not strong enough, far from enough!

After a brief hesitation, Kiyokawa Izumi finally made up her mind to continue using silent calls as the primary method.

He believed that the "Four Forms" he had created was a move that was very close to the Transparent World, and it would be a great pity to give it up.

When the Third Form was created, it was based on the older brother's high-speed dash when he used the final secret technique, and Shinobu Kocho's short-range dash when she used Insect Breathing.

After so long, the segmented bursts I used back then now feel crude and unsightly.

As a greedy adult, he wants both extreme bursts and sustained bursts!

The Silent Three-Stage Technique can also be transformed into the Silent Six-Stage Technique, or even a Nine-Stage Combo—he wants to completely abandon the segmented burst breathing and plug the final loophole in this move.

The Jade Pot he faced was ultimately far inferior to the previous one and three in close combat, and he did not find any obvious flaws in the Silent Three-Stage technique.

If you breathe heavily and your attack is blocked or your breathing is interrupted, you will not be able to use this move, and you may even suffer from excessive breathing.

Let alone the first or third move, using this move against Doma would be suicide.

Its Blood Demon Technique is extremely effective against breathing techniques.

If Kiyokawa Izumi were lucky enough to engage in close combat and dared to use an explosive breathing technique around it, she would only inhale highly toxic ice crystals into her lungs—Doma's blood is highly poisonous, and after freezing, it turns into ice crystal powder, which is then spread through the iron fan.

Daring to use the Silent Three-Stage Technique in front of it is no different from courting death.

Kiyokawa Izumi's short-term idea is to optimize the breathing rhythm of the Dark Breathing Technique, make the Third Form more enduring, and recreate the Land Form, which is mainly based on thrusting.

Finally, there is his ultimate technique, the Seventh Form, which is the ultimate burst of power.

Having achieved this, the self-created breathing method can be considered basically complete.

Its intensity is definitely not comparable to the ceiling-level solar call.

But if he can achieve the best, even in a blank state, he is confident that he can solo the last three upper moons.

If he can't awaken the three-piece set, this is his limit.

It's not weak, but it's definitely not strong either.

Reaching the theoretical limit, Kiyokawa Izumi estimated that he should be able to exchange ten blows with Kokushibo—provided that Kokushibo doesn't take it seriously and doesn't enter the second stage right away.

In his second or even third stage, who could possibly fight Kokushibo in his blank state for three or five moves?
