The tree-god's words had indicated that the ability to break through spacetime limitations existed on this land.
And Oboro could think of only Alluka's Nanika...
One of the Five Great Calamities.
First of all, with his current strength, he could almost fulfill all the prerequisites for wishing, whether it was some form of self-harm or suicide.
At the same time, Nanika of the Zoldyck family was just a juvenile, so there must exist a more mature form of Nanika on this land, releasing even more powerful rule-based power.
He couldn't travel to other worlds on his own...
He needed assistance.
"Another point is that, based on my experience of transmigrating here, the only thing that can break through the barrier is the soul. Moreover, there are differences between the two worlds. Traveling from a high-level world to a low-level world would make the barrier weaker, and the soul would be easier to traverse, but... if traveling to a higher-level space, the pressure on the soul and the success rate of the transmigration might be greatly reduced." Oboro analyzed carefully, while opening the system panel.
The system displayed a garbled interface, performing intelligent calculations based on his thoughts.
It was like a fishing net. He was a fish that had slipped through the net. If he went to a world with a stronger power system... the net holes of the fishing net would be extremely small, and even if his soul could pass through the net and reach the other side, the integrity of the soul that could be preserved would be limited... If he went to a lower-level world, the net holes would be larger, making it easier to break through.
"I already have the experience of transmigrating in this life... If I transmigrate again, the best way is to first go to a lower-level world to verify the possibility of breaking through the spacetime barrier. Otherwise... I might fail and completely disappear in the torrent of spacetime dimensions. In addition, I must retain the ability to continue transmigrating. If it's a lower-level world, my growth space will be small, and the time I stay will not be too long. I must also ensure that one day, I can return to the world of Hunter x Hunter."
"Therefore, the world of this first transmigration is extremely important... First, to experiment with the feasibility of soul traversal. Second... as the tree-god said, to better understand the true nature of the 'Supreme Will.' Third, that world also needs to have rich experimental attributes."
"I hope it works out..."
Oboro murmured.
After a moment, the system generated lines of small text.
"Soul weight reduction, huh?"
Oboro frowned.
According to the system's analysis, Oboro was like a fish, and the smaller the fish, the greater the chance of passing through the 'net.'
In that case...
"Sacrificing a portion of my own soul... to increase the success rate." Oboro instantly understood.
This meant losing some of his power. However, if he allocated and reorganized the limited soul energy.
Then... his overall strength might not be too different.
Overall, it was like an investment. He might have to give up something in the early stages, but the returns he could get in the future would be enormous.
Because this world could no longer accommodate him, and he couldn't go to the depths of the Dark Continent.
The world of Hunter x Hunter currently had no maps for him to grow, no way to grind monsters and gain experience points.
He could only rely on other dimensions to fill in the gaps.
The data given by the system was 70%!
Oboro's success rate of transmigrating to a lower-level world was very high.
But if he were to break through to a higher-level world, the success rate would only be 5%.
'If the host can successfully transmigrate to a new world, ensuring the ability to reincarnate the soul in other spacetimes, as the number of transmigrations increases, the spacetime barrier's restraint on the host will gradually weaken, and the possibility of returning to the world of Hunter x Hunter will also increase.'
'Otherwise, even if the host succeeds in this transmigration, there is a chance of getting lost in the spacetime turbulence, never being able to return to this world.'
"So, the best way is to start from a lower-level world, climbing step by step from worlds with similar power systems, and eventually return to a high position."
Oboro said in a deep voice.
The next task was very simple...
Find a large number of 'Nanika's' kin and control them.
Then, reduce the weight of his soul, traveling light.
Redesign the abilities that could be carried to another world, while meeting the transmigration requirements.
It sounded very troublesome, but for Oboro now, it was just a matter of transforming energy... very simple.
The next second, Oboro unleashed a sea of ghost mist and transmitted the image and information of 'Nanika' to all the spirits, "Find it!"
As the voice fell, countless ghosts scattered in all directions.
In fact, there were many rule-based life forms on this land, and some had abilities far stronger than 'Nanika.'
But most species' rule power had limitations and specific uses.
And 'Nanika' applied rules by presenting them as 'wishes,' so the 'range' that could be affected was large, making it relatively easier to help Oboro, which was why Oboro chose it as his target.
Since it was transmigration, the rule power was best suited to target the 'spacetime' level.
And many rule-based life forms had nothing to do with it.
Whoosh!
Oboro also transformed into a soul state and shot through the air, disappearing into the horizon.
...
"Ai... Ai... Ai!"
Six months later, Oboro stood in a mountainous area resembling a basin, surrounded by shadows like living balls of yarn.
Wandering aimlessly.
Constantly emitting 'Ai' like sounds.
Like frogs in a pond at night, making continuous noises mechanically.
Desire-dependent entities, that is, gas life forms Ai.
Oboro had once suspected that Nanika didn't seem like a gas life form... but that was probably because this rule-based life form had combined with humans.
Nanika was a mutated species.
And these original 'Ai' had not yet 'evolved,' but their abilities were still there.
These life forms could sense desires, parasitizing the bodies of other living things, forming some kind of 'altered organism,' like Nanika.
However, because the object of parasitism and fusion was not an intelligent being like a human, there were still obvious differences.
The most crucial point was that their rule power could be better released and used through human language, and even amplified.
While the 'Ai' parasitizing other species lacked the channels and means to unleash their rule power... Therefore, it also highlighted the importance of humans in the evolutionary sequence.
Whether it was soul parasitism or mental implantation, in essence, it was still an energy combination formed through evolution, the transmission of genes.
If Alluka married and had children, continuing the bloodline, perhaps future generations would be born with the abilities belonging to 'Ai.'
No longer a split will.
At this moment, all the Ai were trapped in this place by Oboro's released ghost mist, like a prison, unable to escape.
"Time is running out... But this number is enough. If condensing such a vast rule power still cannot add a 'special halo' to me that can break through the spacetime barrier, then... I will end here."
Oboro took a deep breath.
He needed to set aside the remaining half a year to transform his soul.
He could transmigrate from Earth to Hunter x Hunter because his soul was originally that of an ordinary person. For the spacetime barrier, this fishing net, he was just a small fish fry, and he only succeeded with some luck. But now... it was different.
"Although you don't have human genes... lacking the advantages of Nanika, I... can make you truly use rules!" Oboro looked at the shadows before him, large and small, and slowly raised his arm, clenching his palm towards all the gas life forms.
With a bang.
The surging ghost mist, like a black sea, soared and billowed, instantly submerging all the 'Ai.'
Using the soul as a medium!
The Ai's life form had almost no dependence on the physical body. Their hunting method was to spread like gas, unknowingly and silently.
The fact that they parasitized souls also made them inherently compatible with the characteristics of 'soul.'
The entire basin was like a pool filled with ink.
The astonishing black tide began to contract and condense among the mountains.
And in the end, all the 'Ai' were connected by soul power, forming a single entity.
Before Oboro, a huge black gas mass gradually appeared, like a giant human face, with facial features.
Oboro mixed countless spirits into it.
"Oboro... can... can... give me... your... brain?"
The oversized gas mass face opened its mouth, emitting a deafening and stuttering humming sound.
Echoing in all directions.
And... it called out Oboro's name.
"Of course."
Oboro smiled slightly.
Then, without hesitation, he raised his hand and stabbed it into his temple. His finger instantly shattered the skull, and he lifted the braincase, revealing the brain tissue inside.
Then, he swung his other hand, and his entire head was severed in an instant, rolling on the ground, turning towards the 'Ai.'
Oboro's headless body also fell to the ground.
However, his life energy did not dissipate with it.
After a short half-minute, accompanied by the rebirth of blood vessels, flesh, and bones, a new head then appeared.
He stood up from the ground again.
With his current abilities, he didn't rely on the physical body as much.
His soul had far transcended the 'post-mortem Nen' recognized by Nen users in the human world, even reaching the point where it could break free from the physical body.
"Oboro... I... want... your... soul."
But the next second, Ai's request made Oboro's expression change slightly.
Although he was the first person to 'wish,' and the forced conditions were not that cruel... it seemed that Ai had sensed his desires and judged the size of the 'wish' based on them.
The conditions and the wish were not entirely unrelated.
"Okay."
He still did not refuse.
It only wanted the soul, not all of his soul... There was a difference here.
He could separate a bit of his soul anyway, which he was going to reduce...
…
A quarter of an hour later, Oboro had fulfilled all the conditions and could finally speak his wish.
"I want the ability to freely traverse spacetime with my soul!"
"Ai."
After the response, the entire mountain area was suddenly filled with brilliant, dazzling white light.
