Jujutsu kaisen : Dust release

Inside the barrier, Onoki watched the building in front of him.

The mental hospital building was well-built, the paint was still fresh and the grass was freshly trimmed, there were iron bars on the windows to prevent any accidents.

Onoki watched the building for a while before they stepped forward.

[Earth Release: Thorns Forest]

Huge stone thorns shot out from the ground towards the mental hospital building, within two seconds there was a huge forest of stone thorns in place of the building.

Each thorn was 10 meters long and half a meter thick so there was no escape from the destruction that had occurred, from the ruins of the building several cursed spirits came out and shot towards Onoki forcefully.

Seeing that, Onoki reached into his pocket and took out a small cylinder, the cylinder was made of white light and inside there was a miniature sword shape.

In the blink of an eye, the cylinder expanded from the size of Onoki's hand to its full size, and likewise the sword inside expanded. Onoki reached out and pierced the cylinder casing, pulling out the sword inside.

This was the Split Soul Katana, Onoki had obtained it from Toji in their battle earlier.

He wanted to test it now.

One by one, the cursed souls were cut through without any resistance at all, the sword passing through them as if it were passing through the air.

Although Onoki had stopped using the sword after learning to release dust in the ninja world, he had not lost his skills over time.

"A good sword, it's good sword, it seems that describing the sword as directly cutting through the soul and ignoring physical defense was not a lie, this sword is as good as the Seven Swords of the Mist." Onoki praised the sword in his hand without reservation.

In the previous world, in order to raise the power of Iwagakura, Onoki collected many artifacts, among them were three of the Seven Mist Swords, unfortunately the method of making the swords was lost to history.

Shibuki the Explosive Sword, Kiba the Thunder Sword and Hiramekari the Flat Sword, after studying the swords for several years, they deciphered how they worked, however, they were unable to replicate such a feat.

Onoki had a hobby of collecting such weapons, so naturally he spared no expense.

After finishing the weak cursed spirit group, Onoki focused on the powerful cursed energy coming from the ruins, without a doubt, this was a special grade cursed spirit.

"Come on, I don't want to spend too much time here." Onoki called out, but it seemed that the cursed spirit couldn't hear him or didn't care about him.

[Earth Release: Earth Dragon]

A huge dragon was formed from stones and shot towards the ruins and pounced towards the cursed spirit.

However, things didn't go as Onoki expected as the head of the rock dragon was destroyed by a massive explosion, the rest of the Earth Dragon's body disintegrated and with its head destroyed, nothing remained of it.

"Oh interesting, you managed to destroy the Earth Dragon with just one strike, worthy of a special grade cursed spirit."

[Earth Release: Light Rock Technique]

Onoki flew into the sky and took a look at the cursed soul on the ground, due to the previous explosion, many debris and hawks were thrown away, making the battlefield cleaner.

At the center of the explosion stood the cursed spirit calmly, it had a normal human body but its head was like a grenade, even its hands were two grenades.

Seeing this, Onoki remembered some information he had read in the file earlier, one of the patients in the mental institution was suffering from post-traumatic stress disorder after an accident on one of the trips, a grenade exploded in front of him, resulting in the death of several of his companions.

Normally, the amount of emotions and cursed energy he produced wouldn't be enough to create a special-grade cursed spirit, but in a place like this mental institution, it was just waiting for its time to happen.

In such places where the concentration of negative emotions is high, the chances of a cursed spirit being born are extremely high, so there were special inspection patrols.

Onoki's train of thought was interrupted by a loud explosion, the cursed spirit was rising into the air using explosions beneath his feet, now that Onoki had a clear look, the cursed spirit's feet were also grenades.

"so you can fly too." Onoki smiled as he canceled his technique.

[Earth Release: Heavy Rock Technique]

[Earth Release: Iron Fist]

Onoki quickly fell towards the cursed spirit as a layer of rocks formed around his right arm, due to the speed of his fall the cursed spirit didn't have a chance to react and was quickly sent backwards.

With a loud thud the cursed spirit hit the ground and created a wide crater, Onoki landed lightly beside it while holding the Split Soul Katana in his left hand.

"It's a pity you're only newly formed, otherwise this would be a rather fun battle but I have to complete the mission quickly."

[Dust Release: Primordial World Separation Technique]

And just like that the cursed spirit disintegrated into dust instantly however there was something left there, a mass of earth rose up and lifted the thing towards him.

Onoki examined it carefully and recognized it immediately.

"Sukuna's finger" Onoki repeated in a low voice, it was now clear why the cursed soul had suddenly evolved to a special grade now, it was because of the special grade cursed item.

Without Sukuna's finger, the cursed soul would probably have been an eternal grade at best.

"Even my technique couldn't destroy it, it seems that what they say about it being indestructible is very true." Despite Onoki saying that, he gave the finger another round of dust release.

However, there was no effect, his cursed technique had no effect on this cursed item.

Onoki wasn't disappointed, but rather found it interesting and tried a different method this time.

"How about this this time?" Onoki waved his Split Soul Katana and forcefully cut the finger, it was supposed to ignore the physical defense and cut the soul directly but still there was no effect.

"It seems that the technique that Sukuna used to split his soul and preserve it is very powerful, even the cursed technique and the Split Soul Katana had no effect on him, unfortunately I have no experience in dealing with souls like this, if it was Orochimaru or the Second Hokage we might have been able to do something about it"

"Perhaps by using the Ghoul Seal or the Rinnegan I would have been able to extract Sukuna's soul inside the finger and destroy it but unfortunately there is no such technique or doujutsu in this world"

Onoki stored the finger and the Split Soul Katana separately in his pocket and started to do something different, earlier after killing the cursed soul this idea occurred to him.

What if he used the cursed soul to produce something, something like a cursed instrument, fortunately Onoki had a cursed technique suitable for the instrument in his mind.

[Reverse Curse Technique: Dust Release: Primordial World Assembly Technique]

A black, translucent cube formed above Onoki's palm and then expanded so much that it became much larger than him.

The positive energy was consumed in abundance, fortunately for him, he did not lack cursed energy.

In the previous days, he had been practicing converting negative energy into positive energy quickly, so there was no fear that the rapid consumption would be beyond his ability to convert.

It took five minutes before Onoki finished what he was doing, the black cube shrank and instantly disappeared, only a sword remained in its place.

The sword was massive and of an unusual shape with two distinct sides, with a narrow cutting edge running along its entire length and a wide platform section on the other side, the scroll unfolding along this last side, sliding down and settling on its surface to form a single section consisting of numerous explosive marks.

This was Shibuki, the Explosion Sword, using the technique from the cursed spirit, Onoki recreated it in this world. In the previous world, this sword was thoroughly studied in the village and the information was engraved in his brain, in the end, it was very easy to create it using the reverse curse technique.
