By Killua's generation, the Zoldyck Family had a total of five children.
From the eldest downward, they were Illumi, Milluki, Killua, Alluka, and Kalluto.
Among the five siblings, Alluka was undoubtedly the most unusual.
A power known as "Request," originating from the Dark Continent, resided within him.
This power possessed wish-granting properties. As long as someone made a Request to Alluka when that power was manifested, it would be fulfilled in an instant.
Up to this point, every Request made to "that power" had been granted.
Thus, the Zoldyck Family had tentatively reached a conclusion.
There was likely no upper limit to the Requests it could fulfill.
But that was precisely what made this power especially terrifying.

Fulfilling a Request came at a Price.
Or rather, the essence of this ability was an equivalent exchange with the nature of a transaction.
Thus, the more difficult a Request was to fulfill, the more "lives" were needed to pay for it...
The Zoldyck Family did not know the origin of this power. They only knew that it was extraordinarily dangerous, and that one misstep could destroy the Zoldyck Family overnight.
So, in order to control the risk, the Zoldyck Family imprisoned Alluka in an underground chamber that never saw sunlight.
But what the Zoldyck Family did not know was...

Demand!
As long as Killua commanded the power within Alluka to do something, no subsequent Price needed to be paid.
Only Killua knew this information.
And as a transmigrator, Moyu naturally knew this hidden information as a reader of the original work.
Moyu had come this time because he wanted Killua to command "that power" to eliminate the Calamity Thermal Light Species, which was currently under containment.
In his view, this
