The Zoldyck Family has five members in total at Killua's generation.
From the eldest to the youngest, they were Illumi, Milluki, Killua, Alluka, and Kalluto.
Among these five brothers, Alluka is the most unique.
It's because within her dwelled a power from the Dark Continent known as 'Request'.
This power possessed wish-granting properties, and as long as one makes a request to Alluka, when the power was active, it would be fulfilled in an instant.
So far, every single wish directed toward 'this power' had been realized.
Therefore, the Zoldyck Family temporarily came to a conclusion.
That is-
There is probably no upper limit to the requests that can be fulfilled.
But precisely because of this, the power was also terrifyingly dangerous.
Because-
Every fulfilled request came with a price.
In other words, the essence of this ability was an equivalent exchange with transactional properties.
Therefore, the more difficult the request is, the more human lives were needed to 'pay' for it...
The people of the Zoldyck Family didn't know the origin of this power. They only knew that this power was extremely dangerous and if they were not careful, the Zoldyck Family would be annihilated overnight.
So in order to mitigate the risk, the Zoldyck Family imprisoned Alluka in a dark underground room, where sunlight never reached.
But what the Zoldyck Family didn't know was...
The power in Alluka's body also possesses another ability that is different from the ability to make wishes:
Command!
If Killua ordered the power within Alluka to fulfill something, there would be no subsequent price to pay.
This secret was known only to Killua.
As a transmigrator, Moses naturally knew this hidden truth as well as a reader of the original work.
The reason Moses had come this time was to ask Killua to command this power to eliminate the Calamity, Thermal Light Species, which is currently under containment.
In his opinion, this was something that could be easily accomplished.
The only obstacle was how to get the Zoldyck Family to agree to let him make a request to 'that power'.
This was the prerequisite.
Only then could the secret of 'Command' remain hidden.
Otherwise, if the Zoldyck Family ever learned about 'Command', Killua and Alluka would completely lose their freedom forever.
As the one asking for help, Moses absolutely did not want to see that happen.
…
"Killua, how much longer is your house arrest?"
Seeing that Killua had agreed to his request, Moses shifted the topic to something more immediate.
As for matters related to Alluka's ability, he couldn't possibly bring them up carelessly here.
Although the other members of the Zoldyck Family were not in the hall at this moment, they were definitely monitoring everything that was going on here.
It seemed that the Zoldyck Family had a certain level of control obsession, and their extensive surveillance systems were proof of that.
"Dad didn't set a time limit."
Killua shook his head.
After removing Illumi's needle, Killua recovered his memories about Alluka.
His precious 'sister' had been locked away in a pitch-black underground cell by his own family...
For Killua, the moment his memories returned, it was followed by a strong sense of guilt.
That was why he had lost his usual composure and acted more recklessly than ever before.
This made Silva very furious and directly gave him an indefinite house arrest punishment.
Now that he thinks about it-
Killua suspected that his father's reaction was largely because this involved Alluka.
"I see…"
Moses nodded slightly.
If he wanted to borrow the power within Alluka, he will definitely not be able to hide it from the eyes of the Zoldyck Family.
So instead of doing it secretly, it was better to put it all on the table openly.
Anyway, as long as the existence of the 'Command' wasn't exposed, everything would be fine.
"Killua."
"Hmm?"
"Tell me about your experiences during this time."
Moses looked at Killua and took the initiative to bring up the topic.
Killua was stunned at first, then seemed to realize something as he met Moses's gaze.
Although there were still some unanswered questions in his mind, Killua went along with Moses's suggestion and began recounting the events that had unfolded since his return to the Zoldyck Family's estate.
Perhaps because these memories were happy ones, Killua's expression gradually brightened as he spoke.
Moses listened with a faint smile, never interrupting Killua's enthusiastic storytelling.
Then, just as Moses had anticipated, when Killua mentioned Alluka, he inevitably brought up the abilities of 'Request' and 'Coaxing'.
The power within Alluka's body is actually another independent soul named Nanika.
When Nanika manifested, Alluka's facial features would turn pitch-black and hollow. At that moment, requests could be made to Nanika.
Once Nanika fulfilled a request, she would revert to Alluka, and Alluka would then collect the 'price'.
The specific method is that Alluka randomly needs to be coaxed by people nearby and would make three requests.
If the person failed to satisfy Alluka's three requests, then the person being asked and the person they loved most would die simultaneously.
And if the price was too great, everyone who had spent significant time with that person would also die, one by one.
In other words-
If the wish-granting ability had no upper limit, then the resulting deaths from the price would also have no limit.
This meant that if the price was too steep, tens of thousands of people could die in an instant.
…
Inside the surveillance room.
All the members of the Zoldyck Family, led by Silva, heard Killua's explanation through the monitors.
"That child Killua, really..."
Kikyo's brows furrowed deeply, and the edges of her red electronic eyes flickered violently, betraying her agitation.
But she ultimately didn't say the word 'naïve'. Instead, she turned to look at her husband beside her.
Noticing Kikyo's gaze, Silva did not react at all and looked at the scene on the surveillance screen with an expressionless face.
His reaction was so still that it was impossible to tell whether he cared that the secret of Alluka's ability had been revealed to an outsider like Moses.
As for Zeno, who held significant authority in the family, he also did not express his opinion, nor did he show any intention to stop Killua from continuing speaking.
It is very likely that he had completely handed over the 'decision-making power' to Silva.
So it is unlikely that he will intervene in this matter.
The one with the strongest reaction in the room was, without a doubt, Illumi.
Having suffered multiple defeats at Moses's hands, he had no confidence in defeating Moses even though he had improved his [Needle Ability].
There was no helping it-
On the road to becoming stronger, no one will stand still. Illumi had to admit that while others were running, Moses was soaring.
He can't catch up at all...
And the gap was only widening.
This harsh reality inevitably made Illumi think about Alluka's power from time to time.
After all, his limbs that were severed by Moses were restored with the help of Alluka's ability.
Such an overpowered wish-granting ability might be his only way to kill Moses.
However, due to the enormous risks associated with the wishing ability, even if Illumi had the idea of using Alluka to eliminate Moses, he couldn't act on it recklessly.
Still, Illumi wasn't in a hurry.
After all, as long as Alluka is under the control of the Zoldyck Family, there will always be a day when his value will be exploited.
However-
Moses' sudden visit, combined with Killua's unfiltered explanation, was tantamount to exposing what Illumi considered his trump card.
Illumi could not allow this to happen.
"Father, if the information about Alluka's abilities is leaked to an outsider..."
"I know."
Silva raised a hand to stop Illumi from saying anything, but his wolf-like eyes remained fixed on the image on the surveillance monitor.
