Controlling the Butterfly Effect from Demon Slayer

With the system's reward in hand, Hori Gaku instantly learned the Lightning Breathing versions of Chidori and Raikiri.

Because the physical fitness required to use these two moves is higher, the system also strengthened Hori Gaku's physical fitness.

In this way, Hori Gaku's strength has risen a lot.

Through self-estimates, Hori Gaku feels that his strength has reached the level of a pillar.

Congratulations, congratulations, facing the upcoming burrowing ghost, Hori Gaku is more confident.

He calmly opened his spiritual vision and glanced down.

Sure enough, under the layers of bluestone slabs, the burrowing ghost was lurking, waiting for the opportunity, ready to go, ready to catch them all in one fell swoop.

Hori Gaku had a blank expression on his face, and calmly grabbed Mitsuri's hand.

Mitsuri was startled, this... is it developing a little too fast?

Hori Gaku's calm words interrupted Mitsuri's fantasies:

"Mi Li, do you believe me?"

"Eh? I...I believe you, Lord Horitake!"

"That's good, Mitsuri, you know, my eyes can see things that ordinary people can't see.

Although Kanroji Mitsuri is a little bit in love, her IQ is not low. After hearing what Horitake said, she instantly understood what he meant:

"Horitake-sama, what do you mean?……"

"Just as you thought, take care of yourself first, and help others if you can."

"I understand."

Except for these two people, no one else knew that there was danger hidden under their feet, and the Ubuyashiki siblings didn't know either. The two of them continued the process of the Demon Slayer Corps:

"First, we will prepare team uniforms for you. After measuring your size, we will embroider your rank on your uniforms."

"There are ten levels in total, namely Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, and Gui."

"Now everyone belongs to the lowest level."

"In addition, today we will let you choose the steel for casting the Nichirin Sword, but it will take another ten to fifteen days until the sword is cast."

"before that……"

Ubuyashiki Teriya clapped his hands, and several crows flew out from the surroundings, crows landing on the shoulders of Horitake and others. Ubuyashiki Hinai took the opportunity to introduce:

"This is a special messenger crow arranged for you, called a 鎹鸦"

"The crows are mainly used for communication and to convey the orders of the Demon Slayer Corps."

After saying this, the Ubuyashiki siblings walked to the sides, showing the table behind them, and lifted the cloth on the table, on which were placed ore steel blocks of different sizes:

"So, these are the steel materials for making swords."

"The steel used to kill demons and protect yourself should be selected by you."

Everyone was eager to try and wanted to go over and select the jade steel.

However, no one took action, but looked at Horitake who was standing in the front.

The meaning was obvious, please let Horitake choose first.

Horitake took the lead and walked over holding Mitsuri's hand. With his spiritual vision turned on, he could see the quality of these steels with a casual glance.

It was worthy of being the steel for forging the Nichirin sword, the quality was good.

Horitake chose for Mitsuri first, and he helped Mitsuri pick up a piece of steel that was neither too big nor too small:

"Mi Li, this is one of the best quality ones."

Mi Li took the steel block:

"Lord Horitake, what about you?"

Horitake picked up a piece of jade steel on his right hand and looked at the ore with interest:

"If I'm not mistaken, this piece of tamaste must have been struck by lightning, and maybe it will be especially suitable for me."

After Horitake and Mitsuri finished their selection, several other people gathered around and began to select tamaste with great interest.

Horitake pulled Mitsuri aside, seemingly indifferent, but in fact, all his attention was on the ground.

Damn, this underground ghost really knows how to hide. At this time, he can still bear not to alert the enemy. Is he really going to suddenly make a move at the last moment, when people are most relaxed?

Well, I have plenty of time, let's take our time.

Just like that, everyone finished their selection, and the Ubuyashiki siblings also wrote down the tamaste selected by everyone.

Finally, the Ubuyashiki siblings bowed slightly to everyone under the torii:

"Then, after your knife is successfully forged, it will be delivered to your residence by the relevant knife maker."

"Congratulations again to everyone who passed the final selection of the Demon Slayer Corps."

Escape Demon, people are about to leave, why don't you take action!?

As expected! He couldn't help it!

Horitake's expression immediately became serious, and he shouted loudly:

"Don't move yet, there is danger under our feet!"

Everyone was shocked by Hori Gaku's sudden warning.

Although they didn't know what happened, because of the prestige Hori Gaku had established, these people really stood there without moving, waiting for Hori's next instructions in a daze. The

Ubuyashiki siblings immediately guessed what happened, and their faces changed. Ubuyashiki Teriya asked anxiously:

"Mr. Horitake, is he down there?"

Horitake nodded:

"He was underground. Fortunately, he couldn't break through so many layers of bluestone and didn't dare to come out, so we……"

Before Horitake could finish his words, the ground began to rumble! The vibration was so strong that people could not stand steadily on the platform.

Mitsuri gritted her teeth and tried to stand firm:

"earthquake?"

"No! It's not an earthquake!" Hori Gaku quickly denied this guess, using his psychic vision to broaden his horizons and observe the surrounding situation:"This... this is... a large-scale ground subsidence!" The underground ghost seemed to have eaten enough people, and its strength reached the level of the lower half of the twelve demon moons!

He launched the blood demon art underground, making the land within a radius of dozens of meters soft, and caused a large-scale vortex-type ground subsidence! The originally calm and solid ground seemed to have turned into a turbulent vortex on the sea!

Crackling, the surging vortex of earth and rocks began to destroy the bluestone platform. The platform could not bear it and began to decompose into pieces of bluestone slabs and collapsed below the ground.

The swordsmen here are all newbies. They have never seen such a crisis scene. They staggered and panicked. They wanted to escape but didn't know where to escape.

All they could hear were a lot of panic shouts:

"This...what is going on?"

"what happened���? The ground collapsed?"

"Why did the ground collapse here?"

"If we continue like this, we will be buried alive. Come up with a solution!"

It's better not to count on them to come up with a solution.

At the critical moment, it was still Hori Gaku who came up with a solution:

"Don't panic! Before the stone slab sinks, everyone quickly climbs up the tree on the stone slab. Don't fall down! If you fall down, you will die!"

Everyone got the guidance and stepped on the few remaining bluestone slabs, ran to the edge of the sinkhole in a panic, and climbed up the wisteria tree.

After confirming that the trees were stable, they breathed a sigh of relief.

Among them, the weakest were the Ubuyashiki siblings.

Although the two children were smart, they were very weak.

After the crisis, the two children did not stand firmly and fell on the stone slabs. Facing the surging mud vortex around them, the siblings were helpless and seemed to have no choice but to wait for death.

Fortunately, Hori Gaku did not forget about them. After confirming that the others were safe, he pulled up the back collars of the two children, and with a breath of thunder, he flashed to the wisteria tree next to him.

Standing on the tree, he looked down at the ground.

Below, the original bluestone platform had completely disappeared, and the bluestone slabs had collapsed into the mud. The few remaining slabs followed the surging mud vortex and spun into the center of the vortex.

Looking at this scene, the Ubuyashiki siblings were still frightened and scared.
