That room was located underground, with two heavy steel doors, resembling the world's most secure bank vault.
Though the room had blue-sky-and-white-cloud wallpaper and was filled with a dazzling array of toys, it couldn't change one fact… it was a prison.
Alluka's [Wish] ability was too buggy and carried considerable risk.
Compared to utilizing Alluka's ability, the Zoldyck Family preferred not to risk it lightly.
They clearly understood that if greed went unchecked and the ability spiraled out of control, it could very likely cause the Zoldyck Family to be destroyed in an instant.
Therefore, they imprisoned Alluka here.
In Silva's eyes, Alluka was [Darkness] that came from somewhere else, not his son.
"Brother, I want to play throw and catch!"
In the room, Alluka's face beamed with a happy smile.
"Okay."
Killua picked up Alluka and threw him into the air.
Alluka let out a string of laughter, sounding very happy.
He hadn't been this happy in who knows how long.
Since being in this room, even the sense of time flowing was gone.
In the corners of the walls and on the ceiling, several surveillance cameras monitored everything in the room.
The footage was transmitted in real-time to the monitoring room, where Silva and Kikyo were present, and Milluki sat before the main control panel.
All three were watching the largest screen in the center, which displayed the feed from the camera mounted on the ceiling, covering the entire room.
Because both parents were present, Milluki didn't dare be too unrestrained… otherwise, the monitoring room floor would have been littered with trash long ago.
"What on earth is Killua trying to do."
Watching Killua playing happily with Alluka on screen, Milluki muttered softly.
Originally, he didn't need to sit in this seat. But as soon as Killua returned, he sought out Alluka, so Silva called him here to monitor the room's situation.
He'd been sitting here for about ten days.
From the moment Killua uttered Alluka's name, including Milluki, all Zoldyck Family's members knew the needle in Killua's head had been removed.
Silva crossed his arms, his gaze on the screen extremely solemn.
He heard Milluki's muttering but wouldn't respond, though he gave an answer in his heart.
What did Killua want to do?
He knew.
It was to take Alluka out of that room.
Compared to Silva's seriousness, Kikyo always looked at Killua with loving eyes. Her red electronic eye frequently trembled, revealing her emotional fluctuations.
Time passed bit by bit… several hours flew by quickly.
On the monitoring screen, Killua and Alluka were like a pair of brothers who never tired of playing, showing no signs of boredom or fatigue.
"Dad, if you ask me, just outright forbid Killua from contacting Alluka."
Resentment continuously accumulated in Milluki's heart. As a member of the Zoldyck Family, his patience as an assassin was the worst in the family.
Deep down, he was almost unable to bear this assignment anymore, having to sit here every day watching Killua and Alluka engage in boring make-believe games.
Silva didn't even look at Milluki, his gaze fixed on the screen.
Ignored by his father, Milluki pouted and could only obediently watch the screen.
At that moment, the monitoring room door opened.
Silva didn't turn around, but Milluki and Kikyo looked towards the door.
The person entering was Illumi.
"Still in the room?"
Illumi wore casual home clothes and came to Silva's side.
"See for yourself," Milluki's tone carried traces of resentment.
Illumi looked at the screen, his dark eyes flickering with a strange light.
"Father."
Illumi looked at Silva and said, "If you find it difficult, help me insert the needle."
Perhaps due to different standing, Silva ignored Milluki but not Illumi.
He turned to meet Illumi's serious gaze and said calmly, "I won't interfere with you, so I certainly won't assist you."
Illumi regretfully shrugged.
Just then, Milluki suddenly grew nervous and said, "Dad, look."
Everyone's attention was immediately drawn by Milluki's words. They quickly looked at the screen and saw Killua take out his phone from his pocket, glance at it, stare for several seconds, then put the phone back in his pocket.
Afterwards, Killua nonchalantly continued playing with Alluka.
"Rewind, zoom in," Silva ordered.
Hearing this, Milluki immediately complied. In less than two seconds, he called up and enlarged the previous scene.
The content on Killua's phone screen clearly appeared before everyone's eyes: a text message from Law.
[Killua, I'm on my way to your place.]
After reading the message content, the monitoring room fell into silence.
"Law is coming."
Milluki cautiously looked at his parents and Illumi beside him, feeling the atmosphere had changed somewhat.
He clearly saw the gravity on Silva and Kikyo's faces and also saw the faint wariness in Illumi's expression.
"That, Law might be coming to collect money from me. I owe him several billion," Milluki cautiously said.
Silva suddenly glared at him, making him shrink his neck.
'Law, oh Law, please don't come stir up trouble.'
Milluki silently thought.
"Father, do you think Law is coming to the house to find Killua or Alluka?" Illumi looked at Silva.
Milluki stared at the screen but pricked up his ears.
Silva didn't answer Illumi's question. Instead, he said, "Netero was severely injured in defeating the Ant King."
"Then you think it's the latter," Illumi said.
"Essentially correct," Silva replied.
"Law is one of the 'people in the know' and an outsider," Illumi reached up, twirling a strand of hair, and said calmly, "Regarding Alluka's matter, he's always been self-aware. But it's also because he hasn't encountered something worth crossing the line for. Now he has."
All along, Law had been one of the 'people in the know', including the matter of the needle in Killua's head.
To minimize risks, given the Zoldyck Family's style, they should have eliminated Law.
However, they couldn't take action against Law.
On one hand, Law was extremely strong… on the other, Law had ties with the family.
Fortunately, Law had never touched that sensitive line. Even though he knew about the needle in Killua's head, even though he knew Alluka was imprisoned, Law hadn't told Killua nor helped him remove the needle.
This approach greatly satisfied the Zoldyck Family. Moreover, Law hadn't sought help from Alluka for his left arm.
But now he was coming, for Netero's sake.
"To prevent the situation from escalating further, make Killua forget Alluka again, and have me make a wish to Alluka to kill Law. What do you think of this suggestion?" Illumi said.
"That's not good," Milluki couldn't help but say.
Illumi simply lightly placed a hand on Milluki's shoulder, and the latter immediately fell silent.
Silva looked coldly at Illumi, who remained expressionless.
"The risk of wishing to kill Law is far greater than the risk of wishing to heal Netero."
"Then can the family refuse Law?" Illumi continued.
Silva, however, fell silent. Regarding this question, it was no longer something he could decide alone.
Once Law arrived, they could only ask Maha to step in.
At the same time, Killua left that room.
