Controlling the Butterfly Effect from Demon Slayer

Spring goes and autumn comes, and a year has passed quickly.

In the past year, Hori Gaku has lived a fulfilling life in Momoyama.

Although the old man Kuwashima Jigoro has a bit of an unreliable personality, he knows a lot. Hori Gaku has learned a lot from this cheap master. Jigoro is also very satisfied with his apprentice, who is practical, capable, and talented.

He is very caring for Hori Gaku, and teaches him everything he knows without hiding anything.

In the first half of the year, Hori Gaku mainly polished his body and practiced swordsmanship. In the second half of the year, Hori Gaku continued to improve his physique and began to learn the Breath of Thunder. The Breath of Thunder is worthy of being one of the five basic breaths at the beginning. The sword is swift and fierce, unstoppable, and has an extraordinary power!

After practicing hard for a period of time, Hori Gaku felt that his Breath of Thunder had begun to get started!

One day in winter, Hori Gaku officially got started with the Breath of Thunder.

There was no premonition, just like a natural process, Horitake had a sense of self-intuition, feeling that after practicing for so long, it was time to succeed!

Standing in the snow, Horitake lowered his head and leaned forward, taking a horse stance, lowering his center of gravity, holding the scabbard at his waist with his left hand and the handle with his right hand.

A breath of air, with a mysterious frequency, was inhaled into Horitake's lungs

""Thunder Breathing·First Form·Thunderbolt Flash!"

In an instant, electric arcs flashed on Horitake's body! He drew his sword out of its sheath! He turned into lightning and flashed forward quickly! A flash of cold light passed by! Horitake sheathed his sword.

Snap! Boom!

A peach tree as thick as a bucket behind Horitake was cut off by his sword and fell into the snow, causing a flurry of snow.

Listening to the sound of the trees falling behind him, Horitake smiled with satisfaction. Thunder Breathing was officially introduced! It was worth it for a whole year of training.

Hmm? There is murderous intent!

At some point, Kuwajima Jigoro appeared behind Horitake, his eyes glowing red, his body emitting black air, like an evil ghost, and his tone was faint:

"You little bastard! You're destroying my peach tree again! Sinai!"

Horitake ran away!

"Smith Masai! Smith Masai! Red bean paste Gomenasai!"

In the snow, one person ran wildly, and the other chased fiercely. The old and the young circled around countless peach trees before they stopped.

Looking at the mad old child Jigoro, Horitake raised his fist and protested while panting:

"You stinky old man! Isn't it just a peach tree? Is that so important? Peach Mountain lacks everything except this thing!"

Ci Wulang was still indignant:

"You little bastard, you've been in Taoshan for a year. How many peach trees have you destroyed? I can't even count them!"

"What can I do?" Hori Gaku complained:"There is nothing on Peach Mountain except peach trees. I practice sword skills not facing peach trees? What should I practice facing?

Compared to this, you old man, you didn't notice that I have already mastered the Lightning Breathing. Not only did you not praise me, but you also made trouble for me. Are these peach trees your disciples or am I your disciple!?"

Hori Gaku complained, and Ji Goro reacted, feeling a little embarrassed, pretending to be profound:

"Hmm? Is that so? I have learned the first form of Thunder Breathing? Although it is slower than when I first started learning, this progress is not bad."

"Stinky old man, are you praising me or belittling me?"

"You don't understand, little brat? Of course I'm praising you!"

"Really? I can't hear any compliments from you at all!"

The daily quarrels started again.

After spending a long time together, Horitake and Jigoro got to know each other better.

Kuwashima Jigoro was undoubtedly an old child. He looked very strict and fierce, but he actually loved his apprentice very much. He was a little insincere and had a very cute personality.

Horitake's personality was a little disrespectful. He seemed to have no respect for Jigoro and often argued with him, but in his heart he respected this little old man very much.

It was precisely because they understood each other that the old and the young would make a fuss almost every day, adding a lot of popularity to the cold mountains.

After the daily quarrels, Horitake and Jigoro gradually returned to silence.

Pretending that nothing had happened, Jigoro coughed twice:

"Ahem, well, overall it's not bad. I've officially mastered the art of Thunder Breathing. I need to keep working hard and keep practicing. I can't slack off.

By the way, after you've finished practicing, remember to chop the fallen peach tree into firewood. It's too much of a nuisance to pile it here."

"I know, that stinky old man, who keeps nagging all day long!"

After Jigoro left, Hori Gaku was the only one left in the snow.

He looked at the gray sky and the snow scene around him, feeling a little melancholy.

This year is the second year of Taisho, when Tanjiro's family was massacred, the beginning of their turbulent life, and the beginning of Demon Slayer.

In the past year in Momoyama, Hori Gaku did not do nothing. In his spare time, he often went down the mountain and looked around in the surrounding towns to find out if there was a family with the surname Kamado nearby.

Unfortunately, there was no news at all.

After being disappointed for a long time, Hori Gaku understood that the Kamado family was obviously not near Momoyama.

Although Neon is an island country, it has a large area and a large population. How could Hori Gaku have the energy to find a needle in a haystack this year? So the search for the protagonist was left unresolved.

Hori Gaku had no way to change the tragedy of the Kamado family.

This gloomy weather, so... Thick snow in this year, maybe these few days will be the time when Tanjiro and his sister will suffer tragedy.

Shaking his head, Hori Gaku no longer thought about things he could not control. What was important was the present and the future!

What had happened could not be undone, but the tragedy that had not happened yet, he must stop it. This was his lifelong goal!

Hori Gaku changed his mood, raised his fighting spirit again, and practiced the first form of Thunder Breathing several times.

As the saying goes, everything is difficult at the beginning. After getting started with Thunder Breathing, Hori Gaku quickly mastered the first form, and this move made him more and more proficient.

Feeling the swiftness and sharpness of Thunder Breathing, Hori Gaku felt very happy.

In the original work, Hori Gaku never learned the first form of Thunder Breathing until his death. Now he has learned it. Is this a manifestation of breaking fate?

As Hori Gaku was thinking about this, an electronic sound rang in Hori Gaku's mind:

"Ding! Detected that the host has broken the fate, the butterfly effect occurs, and the system is officially activated!"

Hori Gaku was suddenly startled, and quickly stopped practicing swordsmanship, standing blankly in the snow.

System!?

Is this... the golden finger online!?

Damn! I have been here for more than ten years! You are just online!? Are you a little late!?

Forget it, it's not too late. After all, strictly speaking, the plot has just begun.

Somewhat helpless, but more of a surprise, Hori Gaku silently said to the system:

""System, tell me, what's your situation? What functions do you have?"

The electronic voice of the system sounded a bit dull, and it seemed that it was not very intelligent:

"Ding! The full name of this system is Butterfly Effect Control System, which is mainly used to control the negative butterfly effect caused by the host and help the host become stronger."

Hori Yue thought silently:

"I know what the butterfly effect is, but can it be controlled?""

"Ding! The butterfly effect can certainly be controlled. If we allow the butterfly effect to occur, it will accumulate and lead to terrible disasters!"

"Well, you are the system and you are right. What did you just say... Control the negative butterfly effect caused by me? Is there a positive and negative butterfly effect?"

"Of course! For example, when the host was a child, he was not as sad as in the original book.���Yu Xingming adopted him, so Xingming did not suffer imprisonment. This is the positive butterfly effect caused by changing fate.

Because it was a positive butterfly effect, the system was not activated.

This time, the host learned the first form of Thunder Breathing, breaking fate, and the butterfly effect caused was a negative butterfly effect, so the system was activated and officially started!"
