Demon Slayer: Muzan, will you dance too?

As the plan unfolds, Kiyokawa Izumi has little time left for training—he has been mainly training his physical fitness with Iwasaki during this period.

He didn't completely abandon his daily combat training, but his challenger had become the Stone Pillar.

Only this person can put immense pressure on him.

Below the waterfall, the water cascades down from an extremely high place, enduring the biting cold while being struck like a heavy hammer.

Perhaps due to the extreme cold, Kiyokawa Izumi, who was shirtless, began to tremble slightly.

The overwhelming force from above made him unconsciously bend over. During his first training session, he always felt like he would be swept away by the water at any moment.

This kind of training is simply torture.

Exquisite swordsmanship is useless at this moment, and even breathing is affected—both swordsmanship and breathing techniques have reached their peak, so making up for the shortcomings is more cost-effective.

For Kiyokawa Izumi, the determination he made was not so casual. It was just this level of training, what was there to give up?

When all the muscles in the body groan in pain under extreme strain, consciousness gradually fades.

On his first attempt, he was almost swept away by the current.

But as he gradually adapted, Kiyoshi Izumi was able to breathe rhythmically under the impact of the water flow.

To avoid losing consciousness, they would also silently calculate the time in their minds.

Concentrate your attention by mentally calculating.

After mastering the techniques, I was indeed not as embarrassed as I was at first.

So he began the second and third training exercises.

The former involves carrying three round logs as thick as an adult male's waist and back to strengthen the lower back and core.

The latter is a bit outrageous; he pushes a boulder much larger than himself for 109 meters.

These three training methods are sufficient to meet Kiyokawa Izumi's requirements.

As for dangerous training like warming his feet by a fire, forget it. He's not made of iron; participating in that kind of training would definitely burn him.

Burns can lead to serious infections, so there's no need to try to toughen up your heat tolerance and willpower by doing so.

Putting aside the fact that the plan was about to begin and he needed to maintain his condition, he was just an ordinary person. His flesh and blood body couldn't withstand the high temperature of the flames—he wasn't as monstrous as the Rock Pillar.

The first two training sessions had already exhausted him.

Take the training of pushing a giant boulder, for example.

Without using explosive methods, it was extremely difficult for him to move the boulder using only his basic strength.

What frustrates him is that such physical training doesn't show results in just one or two days.

With just over ten days of effort, how could they possibly catch up with Mr. Iwasaki, who trains like this day after day?

In addition to spending a lot of time training his physical fitness, he also participated in the upbringing of the three children.

Every afternoon, he would return to the Butterfly House.

There wasn't much else they could do but correct their movements and make their breathing more precise. With the encouragement of the wooden swords and fists, the three little ones managed to barely master the Total Concentration Technique.

Taking the first step towards Pillar-level strength.

According to Kiyokawa Izumi's estimation, their breathing techniques and swordsmanship have both reached level three.

Compared to a real pillar, it is certainly vastly different.

But among the ordinary team members, he still stands out.

Ordinary team members like Murata, despite training for so long, haven't mastered the techniques of Total Concentration and Normal Concentration, and haven't converted them into a considerable level. His breathing technique is probably only at level two.

Swordsmanship is roughly between level two and level three.

Despite spending twice the time and effort, the lack of natural talent cannot change the fact that he will gradually be surpassed by the three little ones.

When Kiyokawa Izumi learned that he was among the team members involved in the plan, his expression was quite strange.

Could Murata participate in such a large-scale event?

As time went by, a month passed in the blink of an eye. With the plan already underway, Kiyokawa Izumi, who had to leave the Butterfly Mansion, was gradually reducing her training volume.

He needs to maintain his condition to prepare for the upcoming fierce battle.

Nestled in a valley surrounded by mountains, a respectable headquarters has been set up, demonstrating that the financial resources of the Ubuyashiki lineage should not be underestimated.

When Kiyokawa Izumi first saw it, he almost thought it was a hidden base.

For the next period of time, he will need to stay here on standby. Also present here are the Wind and Rock Pillars.

Patrolling and active in the surrounding area are the Flame Pillar, Water Pillar, and Mist Pillar.

Intelligence is relayed by the Kasugai crows, and once a battle breaks out, nearby pillars will arrive to provide support immediately, within two hours at the latest.

Waiting is undoubtedly tedious.

They won't wait indefinitely.

If the upper moon doesn't appear within a month, then the plan will unfortunately have to be declared a failure.

"Kiyokawa Izumi, do you really think we'll encounter the Upper Moon?"

Feeling equally impatient, Kaze Pillar wanted to spar with Kiyokawa Izumi again, hoping that he could give him a positive answer.

As a Pillar who has encountered the Upper Moon several times, his response is undoubtedly convincing.

"It will be a fierce battle, barring any unforeseen circumstances."

"Really? That makes me really excited!"

The hot-tempered guy was getting a little excited.
