I started with Emperor Armor and conquered Infinity.

Chapter 104 Extended Time

Shinobu Kocho's eyes were calm and focused as she watched the Hand Demon's every move. Then, her gaze sharpened, and she moved like lightning, rushing forward in an instant.

He leaped into the air and raised his Nichirin Blade high.

The Nichirin Blade in his hand gleamed coldly in the sunlight. With a slight twist of his wrist, the blade traced a graceful arc in the air before slashing viciously at the Hand Demon's weak point.

The blade flashed, and before the Hand Demon could even retaliate, it was annihilated by the strike.

The massive body seemed to lose its support and collapsed with a crash, making the ground tremble.

Shinobu landed steadily on the ground, her hair fluttering slightly, her gaze calm as she looked at the enemy she had just defeated.

"Why are you so fast?"

The severed head of the Hand Demon, lying on the ground, stared resentfully at Shinobu Kocho, its crimson eyes filled with incomprehension and hatred.

"It's just that you're too weak."

Shinobu Kocho said softly.

"I'm too weak?! I've become this wretched state, and the power I'm pursuing is still too weak, no..."

The Hand Demon muttered to itself, roared, and then transformed into wisps of black smoke, slowly dissipating into the air...

"(???)"

Not far away, Sabito, Makomo, Tanjiro Kamado, Nezuko Kamado, Zenitsu Agatsuma, and Inosuke Hashibira were watching.

This woman's strength is truly terrifying. She managed to kill the Hand Demon, which even a Class A Demon Slayer Corps member would have difficulty dealing with, with a single strike.

The difference between them is just too big.

Their previous guesses were a bit conservative; perhaps Shinobu Kocho already possessed Pillar-level strength.

A young lady who looked not much older than them was so much stronger than them; they would have to train even harder...

"He's here to join in the fun again. It's annoying. He really doesn't know what he's getting himself into."

Watching the massive body of the Hand Demon slowly dissipate, Shinobu Kocho turned her head to look at the commotion not far away, shook her head, and said softly.

Not long after she had just killed the powerful Hand Demon, more than a dozen evil spirits tried to ambush her, surrounding Shinobu Kocho from different directions.

Its ferocious face, its eyes that craved flesh and blood, and its body that was more than two meters tall, far taller than his own 151cm height, seemed to block out the surrounding sunlight.

This caused Shinobu Kocho to slightly raise her bright purple eyes and slowly scan the area, her gaze sharp and intense.

These evil spirits are quite powerful; if it were an ordinary person, they would only be slowly tortured to death.

Even now, her physique is still slightly inferior to those demons who have been enhanced by Muzan's blood.

Unfortunately, these guys were no match for me in speed, let alone the power I could unleash using breathing techniques and my true energy.

"What's the use of being physically stronger if you can't match my speed and explosive power? It's completely meaningless."

A thought flashed through Shinobu's mind, and she dodged a sneak attack from a demon.

The next moment, the Nichirin Blade in his hand swept through a graceful arc, and the demon's arm was severed, falling to the ground like trash.

Then, Shinobu Kocho once again unleashed her astonishing speed and agility, leaping back and forth between the demons.

This was achieved without utilizing the full concentration of breathing techniques; solely through the influence of breathing techniques and true qi, an extremely powerful burst of movement and slashing was accomplished.

A leap, a flash, a swing, a slash.

The movements were fluid and precise, each strike a fatal blow, without any unnecessary actions.

When Tanjiro Kamado and his six companions, who were preparing to come and help, arrived at the meadow, there were already more than ten demon bodies on the ground.

On the other side of the live stream, everyone who saw this battle scene looked at Lin Yao with admiration.

This very person brought about a dramatic change to the Demon Slayer Corps, increasing their combat strength and gradually extending their influence to some remote areas.

These measures have led to an astonishing leap in the overall strength of the Demon Slayer Corps.

In terms of examples of personal improvement, Shinobu Kocho is the most vivid one.

Previously limited by her physical condition, Shinobu Kocho, who worked hard to train but achieved little, had a certain reputation within the Demon Slayer Corps.

It's not just because of her hard work, stunning looks and abilities, and somewhat resolute personality, but also because of her gentle older sister.

Now, everyone has witnessed Shinobu Kocho's amazing performance through the live stream and, after understanding her strength, they all know clearly who brought about the change.

……

"Sister, you're amazing."

Upon approaching Shinobu Kocho, Makomo, with her cheerful personality, spoke first in a gentle tone.

Others nodded in agreement.

As for Hashibira Inosuke, who is usually very active among the six, he didn't make a silly move this time, but looked at Kocho Shinobu with the eyes of someone looking at a monster.

His eyes were filled with shock and longing; he was already fantasizing about when he could become that strong.

If I could become that strong, then fighting those evil spirits wouldn't be a piece of cake.

"My name is Shinobu Kocho. I'm just a bit older than you. When you're my age, you'll have this kind of strength too."

Hearing this tone, Shinobu Kocho felt a strange sense of familiarity, as if this was a younger version of her older sister, and immediately smiled and said.

"At your young age, you have already gained Yao Jun's favor, which clearly shows that you have extraordinary abilities. Perhaps when you are the same age in the future, your strength will be even greater than mine."

He glanced at the five people behind Makomo: Sabito, Tanjiro Kamado, Nezuko Kamado, Zenitsu Agatsuma, and Inosuke Hashibira. Not one of them was a coward.

Coupled with the battle aura emanating from these people, Shinobu Kocho nodded, expressing her encouragement.

"We will."

Tanjiro Kamado and the others answered earnestly in unison.

……

After Lin Yao planted his influence among the high-ranking members of the Demon Slayer Corps and among the new recruits, he established his influence.

This allowed them to further refine their plans within the Demon Slayer world and develop the ability to cope with risks.

But Lin Yao was not satisfied with just that.

Next, there was another thing that solidified his supreme prestige within the Demon Slayer Corps: finding Muzan.

There's not much remaining value to Lin Yao to exploit now, so it's better to just kill Muzan.

Compared to the great battle five years later in the original timeline, where many Pillars died or were injured, resulting in Demon Slayer becoming Pillar Slayer, this story is a far cry from the original.

With Lin Yao as a powerful combatant, the overall potential and strength of the Demon Slayer Corps can be improved.

This allowed the Demon Slayer Corps, which had been at a disadvantage and even had to hide, fearing that Muzan and the Upper Moon demons would come after them, to regain the initiative.

This marks the Demon Slayer Corps' resurgence since Yoriichi Tsugikuni's death.

Now, Lin Yao feels that his previous plan to extend the mission time was very appropriate.

After all, this choice was necessary to better coordinate the extermination of Muzan and eliminate some forces that colluded with him.

Ultimately, the planning behind this is enough to change the entire mission world.

Even with Lin Yao's current apparent strength, he would need to gather all possible solutions to find those two-faced villains and the hiding Muzan.

One can imagine how generous the rewards must be for completing this task.

Even setting aside the elimination of related forces, the reward for simply killing Muzan would allow a formal reincarnator to experience a significant boost in strength.

Not to mention Lin Yao, who was just an apprentice reincarnator.

Of course, unless absolutely necessary, Lin Yao was unwilling to activate the Emperor's cheat and initiate a worldwide manhunt.

If you need to activate the Emperor Armor to fight Muzan, that would be incredibly embarrassing.

Even if I were to activate my armor, the enemy I faced would at least be a powerful late-stage Nascent Soul Realm expert, a level of power that is as terrifying as the Canglan Realm.

……

As three months passed in the blink of an eye, Lin Yao's influence on the Demon Slayer world reached an extremely terrifying level.

At the same time, those reincarnation points that were originally used for settlement in this world have transformed into something like energy points, which are shortening at a certain rate.

Based on the patterns within, Lin Yao also calculated how long he could stay in this world, given that he only had reincarnation points and the blessing of sect-level authority.

Nine months!

This is the maximum time that the mission world can be extended. Adding the previous three months, it actually reaches exactly one year.

Although defeating Muzan would definitely result in a significant increase in reincarnation points and plot points, it's really unnecessary.

A year is enough time for many things to change.

It seems I can stay in this world for another nine months.

It seems like a long time, spanning three seasons, which is more than three times the base period of three months.

But this is Lin Yao in the Demon Slayer world, who subdued the Demon Slayer Corps, slayed evil demons, and wiped out the dark people, spreading his influence to the grassroots.

The terrifying effects of these measures barely lasted for nine months.

It's no wonder that this extended privilege at the clan level is disliked by others.

For seasoned reincarnators, spending a huge amount of reincarnation points to extend their time by half a month or even a month is indeed too insignificant.

This 1:9 ratio, especially considering the increasingly rapid rate of energy consumption, demonstrates the immense gains Lin Yao made while working tirelessly in the Demon Slayer world.

……

Slow and steady wins the race. When Lin Yao learned that he could only stay in this world for nine months, he did not rush to find Muzan.

Instead, they systematically planned a training program to enhance their own strength, as well as that of Kanae Kocho, Shinobu Kocho, and others.

At the same time, nearly half of that time was spent making various minor adjustments to the Demon Slayer Corps.

By extending its reach to the grassroots level and extracting enough fresh blood, the Demon Slayer Corps can grow and thrive in a very short time.

Even if he summons members of the Demon Slayer Corps to other mission worlds, there won't be any major problems due to temporary casualties or power transfers.

Moreover, in order to maintain the purity of his team, Lin Yao also began a bloody purge, removing the spies of those who had benefited from the system.

Lin Yao's main purpose in going to great lengths was to protect the people he cherished and to make himself more adept at using the Demon Slayer Corps.

Meanwhile, during these four and a half months, Lin Yao also discovered that his speed of cultivating true qi had slowed down to a certain extent, just as the Samsara Space had indicated.

Even 7 months later.

If Lin Yao hadn't cultivated the high-grade Earth-level technique, the Prison Demon Body, and possessed the Myriad Fires Body, he would have doubted that his cultivation speed had stopped.

Even so, compared to the surging true energy like a rolling river before, the current stream of true energy, like a babbling brook, made Lin Yao very uncomfortable.

However, despite the various limitations, the boost from these two cultivation accelerators still allowed Lin Yao to make significant progress during his seven months of cultivation.

Leaving aside improvements in mental strength, physical strength, martial arts skills, and other aspects.

Even with true qi cultivation, one can steadily break through one star per month.

The eighth level of the foundation building realm!

This is Lin Yao's current level of true qi cultivation.
