Oboro's Concerns

Jigoro Kuwajima was Zenitsu's teacher.

Sakonji Urokodaki trained characters including Tanjiro, as well as Giyu Tomioka, Sabito, Makomo Giyu Tomioka.

Kamado Tanjuro has also been born.

On Muzan's side, there are also a few Lower Moons that Oboro can name, such as Ubume and Hairo.

Unfortunately, the era in which these two Lower Moons lived had completely deviated from the original story, and they were killed just as they were beginning to show their talents.

Muzan has far too many enemies.

The changing environment even prompted the Taisho era government to publish a book to record and update the current situation from all sides.

So that people can better guard against ghosts.

In the current Demon Slayer world, everything is already transparent.

Muzan is the progenitor of demons, as everyone knows.

The inheritors are guided by the God of Imperial Martial Might to reform all of humanity and change the world.

They are 'cultists' among ghosts.

They believe the world is 'broken' now.

Unlike the demons under Muzan's command, they adhere to a twisted ideology.

The God of Imperial Martial Might refers to Oboro.

However, humans do not believe this claim.

In human culture, Oboro, representing the God of Imperial Martial Might, is God symbolizing power.

It brings hope to humankind.

It is a benevolent deity full of positive energy.

The person mentioned by the inheritor is not the same one at all.

As for the Demon Slayer Corps, which remained unknown to the public, it has long been exposed.

This is a ghost-hunting organization that has existed since ancient times...

In addition, large and small strongholds were built in various regions of the country to centralize the scattered population and prevent some people from being turned into ghosts.

Nowadays, there are very few people living in remote wilderness areas, like the hunters of the past.

The most typical example is the small town where Oboro lives. Even though the population is small, it has erected towering city walls... All of these changes have occurred in recent years.

It can be said that the current Demon Slayer world, while still maintaining its 'original' tone, has a completely different social landscape, power structure, and power system from the original work, and is developing in a new direction and on a new path.

The will of the Demon Slayer world, that Little Tree, has finally borne unripe fruit.

It's just not mature yet.

Long had a premonition that she was about to leave.

I can't wait for the story to start...

Several seeds successfully hatched and grew.

Some were discarded.

First, the power of the soul... allowed ghosts to collectively evolve to another level, but they didn't achieve anything remarkable.

For example, he could use his soul power to create methods and cultivation techniques that he had never researched or even conceived of.

Therefore, this part can only be recycled.

Regardless of Muzan ultimately lives or dies, his Blood Demon Art, techniques, and bloodline will all be transformed into cards.

They were taken to the next world by Oboro.

From a harvest perspective, this seed was a failure.

However, in terms of helping to improve the power system of the Demon Slayer world, its role is incredibly significant.

The second seed is Gyutaro.

Like Muzan, he contributed to the overall growth of the world.

As for elevating combat skills to a more transcendent level, that's still impossible in the world of Demon Slayer.

Even though many people study Gyutaro and have even figured out his movements, footwork, and attack techniques in battle, they are at most imitating, learning, and developing downwards.

There's no way to reach the next level.

Pure martial arts have a very weak foundation in Demon Slayer.

Apart from Akaza, who died, there doesn't seem to be a second notable figure.

There are ninjas in Demon Slayer, and they all practice killing techniques... but they are nothing compared to the Zoldyck Family.

When the information hidden in the shadows of this world is fully exposed, and all the 'key figures' are brought into the light, their 'every move' will be closely watched, regardless of whether they are human or ghost.

The appearance of Gyutaro has enriched the foundation of martial arts in this world.

Although it still belongs to a niche market.

The third seed, naturally, is breathing exercises.

Now in his sixties, Kamado Tanjuro has mastered the art of 'kikuchi' (Qi Acupoint).

It's somewhat similar to what Oboro understands as 'opening up the Ren and Du meridians'.

Yet, there are some differences.

Kamado Tanjuro can use his breathing to send 'ki' into certain acupoints through internal energy and store it, displaying superhuman strength when it erupts.

He figured all of this out on his own, without any interference from Oboro.

On the Demon Slayer Corps' side, there's another training path derived from breathing techniques, called 'Qi Vortex'.

It shares similarities with the cultivation method of Qi Acupoint, but also has its own unique aspects.

It involves distributing Qi (vital energy) throughout the muscles and blood of various parts of the body, compressing it infinitely, and forming a 'miniature circulation system' to the maximum extent. It's like installing an invisible engine in each part of the body, and before the Qi is exhausted, the strength will be greatly amplified.

The Qi Acupoint is for releasing, Qi Vortex is for gathering.

Kamado Tanjuro Qi Acupoint) allows him to utilize acupoints throughout his body, forming a line from points, and unleashing a burst of stored energy when used.

There is no obstruction to the blood, flesh, meridians, etc. in the body.

The Demon Slayer Corps' Qi Vortex are not released outwards, but rather the energy is stored in specific parts of the body and activated. The size and magnitude of the internal energy circulation are limited, and it is impossible to store them. They can only maintain the state of each Qi Vortex by breathing exercises on a daily basis.

This seed has been successfully planted! As soon as Oboro observed these two forces, the system immediately began to simulate and calculate.

It took a long time, and finally, combining his memories from his time on Earth, he came up with an advanced version of the breathing technique.

It has gone beyond the framework of Chinese Martial Arts.

When one's wish is fulfilled, it becomes a method.

Dantian and Qi Sea.

A method of controlling Qi that, even if it doesn't actually originate from Earth, is still inextricably linked to it.

From breathing exercises to Qi cultivation.

Long was happy, but not to the point of being ecstatic.

It involves the word 'law'.

This indicates that this method... absolutely surpasses the power sources of most advanced worlds.

But there's no guarantee he'll be absolutely safe in the next world.

Oboro truly hadn't expected... that in the lowly world of Demon Slayer, the upstream power of breathing could be deduced.

Whether it's the Kamado Clan or the Demon Slayer Corps, they all bear the burden of 'inheritance'.

Oboro initially approached it with a "let's give it a try" attitude, and surprisingly, she actually succeeded.

His determination to carry on the legacy impressed him once again.

Members of the Demon Slayer Corps would not dedicate themselves to studying breathing techniques if they weren't focused on slaying demons.

If the Kamado Clan hadn't strived to better continue the "Sun Breathing," Tanjiro Kamado wouldn't have achieved what he has today.

"If one can master this method and truly achieve the dantian and qi sea... then, at least in the higher worlds, one can become a 'land immortal'," Long thought to himself.

Even he, when breathing, only sensed the qi and utilized it.

But things like the dantian are too mystical.

It was as if this power was something he had never been able to touch before.

But now, the system has provided the optimal training plan.

"Something that couldn't be done even in Hunter x Hunter, was actually accomplished in Demon Slayer. Unbelievable..."

"But... what I'm worried about isn't just the power system and environment of the next world, but also the will of that world. If... it wants to eliminate me, this stowaway... and doesn't give me any time to grow, even if there's a way to become a terrestrial immortal, I'm afraid I'll perish prematurely."

Long was well aware of his situation.

The will of the Demon Slayer world sought cooperation because it had no other way to deal with him... there was an element of gambling involved.

A time traveler like him is not on the timeline of destiny in any world... His appearance is very likely to be destructive.

It causes the world's trajectory to shift.

In other words, it's a virus.

This is why he wasn't particularly excited about obtaining the Qi Refining Method.

The key lies in the soul!

Later, in the initial stages of traveling to any world, all he could rely on were his soul and the system's abilities.

Only by establishing a foothold with these two forces can other means be gradually consolidated.
