Controlling the Butterfly Effect from Demon Slayer

Zenitsu was so excited that he dragged Koutsuka into the house and treated him to good tea, water, and snacks. He also massaged Koutsuka's shoulders and legs and fanned him. He was so attentive.

Koutsuka had never seen such a scene before. He sat stiffly on the tatami, feeling a little overwhelmed.

"Um... please tell me……"

"Yes! What can I do for you?"

"Excuse me...are you Horitake?"

"Me? No, I'm Horitake's junior. Brother Horitake just went out for training."

A drop of cold sweat broke out on Gangkuaizuka's head.

You are not Horitake himself, why are you so attentive? It makes me feel uncomfortable.

"Um... could you please ask your senior brother to come over and get the knife?"

"OK! I'll go call him right away!"

Zenitsu opened the door and shouted to the outside:

""Brother! Your Nichirin Sword has arrived!"

The voice was loud, echoing in Taoshan.

A few minutes later, Horitake and Jigoro arrived together.

Opening the door and entering the house, Horitake looked at the waiting Tetsutsuka with some anticipation:

"Oh? Is my Sun Blade ready? Are you my swordsmith? Thank you so much for your help."

The others sat down as host and guest, and Tietsuzuka finally got into his own rhythm. He opened the Sun Blade's package and talked to himself:

"This is the Sun Blade, which I forged myself.

The raw materials for forging the Sun Blade come from the mountains closest to the sun, the red sand iron and the red ore.

Therefore, the forged sword can absorb sunlight.

Because Sunshine Mountain is a mountain that is illuminated by sunlight all day long, there are no clouds or rain on the mountain.……"

Hearing this setting, Hori Gaku couldn't help but complain in his heart.

Selected from the highest mountain closest to the sun, it can get sunshine all day long, there will be no rain and no clouds on the mountain, are you talking about... Mount Everest?

I don't believe you can mine iron ore from Mount Everest.

Besides, there is also day and night on Mount Everest, and it is not sunny all day long.

So this setting is outrageous.

Or is there no such thing at all, and these swordsmiths are just bragging?

While complaining in his heart, Tietzuka had already taken out the Nichirin Sword from the box and handed it to Hori Gaku.

Hori Gaku solemnly took his sword.

Take a closer look at this Nichirin Sword. The scabbard and handle of this sword are dark red. The style of the sword is not the traditional Japanese samurai sword, but the style of the Chinese Tang sword.

Of course, the reason why it is the Tang sword style is also Hori Gaku's request in advance.

Looking at the overall style of this sword, Hori Gaku was very satisfied:

"Master Tietuozuka, thank you for agreeing to my willful request and forging my sword into the Tang sword style."

"This is not a difficult thing. After all, the Japanese samurai sword is derived from the Chinese Tang sword. It is a good experience for me to reproduce the craftsmanship of my ancestors occasionally.

However, I did encounter difficulties when forging this sword."

"Oh? What's the problem?"

Tietuozuka pointed at the knife in Horitake's hand and said bitterly:

"I don't know what's wrong with the jade steel you chose. It seems to have lightning inside.

Every time I forge this jade steel, it always shocks me in return. After a few forgings, my arm becomes numb. There is really no other way, so several of us take turns forging, and gradually forge this sword into shape."

On the side, the knowledgeable Ji Wulang was also shocked when he heard this:

"Is there such a thing? The sword with the power of lightning chose Horitake who used the breath of thunder. Is this fate!?"

Horitake could probably guess what was going on.

When he chose the tama steel, he scanned it with his spiritual vision. The tama steel he chose was struck by lightning, so it might contain some characteristics of lightning.

Before Horitake officially drew his sword, Kōtetsuka couldn't wait any longer and urged:

"The Nichirin Sword can change color according to the characteristics of the user. Come on, pull out the sword and see what color it can turn into. I really hope it can turn into a scarlet red sword!"

Hori Gaku was also looking forward to it and slowly pulled out the Nichirin Sword.

The Nichirin Sword in the style of a Tang sword has a silver-white blade and a very sharp edge.

Under everyone's attention, the Nichirin Sword began to slowly change color along the handle.

"Mouth... mouth tired wow……"Kotetsuka was shocked.

The Sun Blade turned into a dazzling purple color, with lightning patterns interlaced between the purple colors, looking extremely mysterious!

Zenitsu was dumbfounded and muttered to himself:

"What a beautiful purple! This color... is the same color as the lightning released when my brother uses Thunder Breathing!"

Ketsuzuka was even more excited:

"Nani Koulei! ? (What is this!?) This dazzling color... has never been recorded before! It's amazing! Maybe I witnessed a miracle!"

Jigoro looked at Horitake with relief and suggested:

"Horitake, please give your Nichirin sword a name!"

"Pick a name……"Horitake pondered for a while and came up with an idea.

He looked at his knife, gently slid his hand over the blade, and said lovingly:

"Let's name it... Mighty Light! Its name is the Blade of Mighty Light!"

"Weiguang? What a good name! Where does it come from? What story is it from?"

"It's not an allusion, it comes from……"

Horitake Tsuyoshi wanted to ask where it came from, but suddenly something strange happened!

A purple arc suddenly flashed on the Blade of Power, and the arc flashed in the sky!

Everyone present was startled, and Jigoro asked quickly:

"Horitake! What's going on!?"

"I don't know! I didn't use the Breath of Thunder! It was the Lightning that released the lightning on its own."

Iron Mound didn't notice anything unusual at all, and was still dancing around:

"Is it possible to release lightning by itself? Is it the magic of the jade steel? It seems that I have forged an incredible sword!"

"No!" Hori looked at the mighty light and denied:"It's not what you said, I feel like the mighty light is...provoking! ?"

"Provocation?"Looking at the flashing purple arc, Jigoro was puzzled:"Provoke who? Provoke you?"

It's not surprising that Jigoro has such a guess.

According to legend, some powerful weapons also recognize people. If the user is not strong enough and cannot pass the test given by the weapon, the weapon will not recognize the user, and may even devour the master!

Horitake shook his head and denied this guess:

"No, the lightning released by the mighty light did not shock me. Instead, I felt very compatible with the mighty light. The mighty light seemed to be challenging me.……"

Following the direction of the arc released by the mighty light, Hori Gaku looked up.

Challenging the ceiling? No.

Challenging the sky outside? It doesn't seem right either.

Could it be...

Hori Gaku had a thrilling guess.

At some point, the clear weather outside suddenly became overcast.

Hori Gaku sensed something, opened the door, and looked up at the sky!

The heavy, gloomy clouds enveloped the entire Taoshan Mountain, pressing towards the mountain, giving people a sense of oppression and threat.

Tietsuzuka scratched his head, feeling very strange:

"The weather was fine just now, how come it suddenly changed?"

Ji Goro's face looked very ugly, he remembered an incident that happened before, that is, Zenitsu was struck by lightning and his hair color changed.

How similar is this scene to the previous one!?

However, the quality is incomparable, the dark cloud that struck Zenitsu at that time was only one layer, and it dissipated after being struck, but this time the dark cloud has covered the entire Momoyama!

Thinking of this, Ji Goro leaned on his crutches, secretly complaining in his heart:

Why do his own disciples have to experience such inhuman treatment!?
