In his previous life, Ron had seen Killua in the original storyline.
However, in this world, Ron hadn't officially met Killua yet.
"If it's convenient, could you provide me with some information about Killua when he arrives?"
As he spoke, Ron suddenly heard a brief, somewhat sly laugh over the phone.
"It would be even better if you could get me a photo of Killua defeated, lying on the ground."
Ron raised an eyebrow slightly.
"Alright, if it's convenient, I'll provide some."
"Thanks a lot! I'll pay you ten thousand Jenny for each photo!"
It wasn't much money, and it wasn't difficult to obtain.
Ron didn't even need to take action himself.
He could simply have Chii capture some images from surveillance footage.
Ron already had the task of secretly watching over Killua.
This was just a side task.
"Looks like only Uncle Silva, Grandpa Zeno, Aunt Kikyo, and Kalluto know about my mission to watch over Killua."
"Killua himself, Illumi, Milluki, and Alluka don't know."
Shizuku had forgotten much about what happened yesterday, but her body naturally began practising the technique of Ten.
Upon waking up in the morning, the first thing she did was open her notebook.
"Shizuku, let's test your Nen affinity."
"Lisa, want to join us?"
"Sure, give me a moment."
The three of them left the room and went to the living room, where Ron was already sitting at the dining table.
Breakfast had been delivered by the staff of the Sky Arena restaurant.
It was a lavish spread.
Since Chii had completed the establishment of their intelligence network, Ron was never short of money.
If Nina won her matches, she could also earn a considerable amount of prize money.
But to be honest, relying solely on Nina's winnings wasn't enough.
This is the Sky Arena.
It's the most expensive place in the entire city.
And they're on such a high floor as the 200th level.
However, Ron didn't suggest going to other areas downstairs because the items there weren't cost-effective or practical. That would waste too much time. The time of Ron and his team was worth much more than the price difference.
Sally also changed her form of address following Shizuku.
"Let's have breakfast."
"Big Brother, we want to test Shizuku's Nen affinity."
Nina said as she took a glass, filled it with water, and then went to the balcony. She plucked a leaf from the greenery and placed it on the water's surface.
Shizuku took the glass, holding it with both hands.
Then, she concentrated a large amount of aura towards her hands.
In the next moment, numerous crystals appeared in the water inside the glass.
"Just like me, a Conjuration type."
Ron had already known this.
Compared to the original storyline, Shizuku's fate had changed.
She didn't join the Phantom Troupe but became part of Ron's team.
However, her Nen affinity wouldn't change.
But Ron wasn't sure if the Nen ability Shizuku would develop might be different.
After breakfast, Ron continued teaching Shizuku the basics of Nen.
"Zetsu is the technique of closing all the body's aura nodes."
"Gyo focuses aura into the eyes, allowing you to see the presence of aura."
"Ren can refine more aura."
"As for Hatsu, once you've mastered the above techniques, you can try developing your specific Nen ability."
As Ron spoke, he paused for a moment.
"Shizuku, after you've mastered all the techniques except Hatsu, you can participate in matches at the Sky Arena."
"Below the 200th floor, don't use Nen in battles, just like Nina."
"Engaging in some real combat will be very helpful to you."
Shizuku nodded, took out her notebook, and jotted it down.
In the morning, Ron taught Shizuku, and in the afternoon, he instructed Nina and Sally.
He taught the two of them advanced Nen techniques.
While teaching, Ron was also practising himself.
During the process of instructing Nina and Sally, Ron could organize and fine-tune the techniques he had already mastered by addressing the issues they encountered.
The effect was even better than practising alone.
This reminded Ron of some scenes from his previous life.
When he was still in school, in elementary school, the teacher would ask him to help explain to classmates who weren't doing well.
When he reached middle and high school, he would take time to help his good friends with their studies.
In the process of explaining, he often gained new insights himself.
"It's similar to what I'm doing now."
Ron took out his phone and answered.
Silva's voice came through.
"I've brought Killua to the Sky Arena. I have to go on a mission now. In the coming period, please watch over Killua in secret."
"Alright, no problem."
After hanging up, Ron had a thought.
"Chii, locate this person for me."
Chii immediately began the search and quickly obtained the result.
Content from a surveillance video was transmitted to Ron's laptop.
A little boy with spiky white hair was wandering around the first floor of the Sky Arena.
This was Killua's first time leaving the Zoldyck estate.
It was also his first time coming to the Sky Arena.
Therefore, he was curious about everything around him.
Some gazes fell upon Killua but quickly moved away.
Others looked at Killua and became interested in him.
Killua stopped in front of a vending machine, studying it for a while.
Then, he walked to the front desk on the first floor to register for matches.
Because Killua had no money on him, he couldn't buy anything.
He didn't even have enough for the minimum purchase from the vending machine.
When Silva brought Killua here, he only provided him with a month's hotel stay.
And corresponding meals for each day.
Besides that, he didn't give Killua a single penny.
Therefore, Killua couldn't even buy a bottle of cola.
But then again, the prize money for winning on the first floor of the Sky Arena was only enough to buy a bottle of cola.
Ron captured Killua's hesitant expression in front of the vending machine.
Then, he sent it to Milluki via email.
Milluki opened the email, his eyes lighting up.
"Look at that expression."
"He didn't even show that face when being whipped."
"He can't even afford a bottle of cola. How pathetic!" (t/n who needs enemies when you have a Brother like Milluki)
A single photo gave Milluki psychological satisfaction. Without hesitation, he transferred ten thousand Jenny to Ron's account.
Ron raised an eyebrow slightly.
"I wonder what kind of expression Killua would have if he saw these photos in the future."
According to the Zoldyck family's way of thinking.
Even if Killua found out, he'd go after Milluki instead of Ron.
It's just like how people killed by the Zoldyck family usually don't seek revenge on the Zoldycks but rather on the ones who hired them.
Ron remembered that in the original storyline.
The Ten Dons were killed by the Zoldycks. But they went after Phantom Troupe insteed.
However afterwards, once the world's mafia learned that the Phantom Troupe members were from Meteor City, they would abandon their revenge.
