Throughout the day.
Aoki kept unlocking the Gene Lock, practicing various techniques.
Lightning Release: Thunderclap!
Lightning Release: Falling Thunder!
Lightning Release: Thunder Dragon Tornado!
Lightning Release: Thunder Beast Pursuit!
Lightning Release: False Darkness!
Lightning Release: Heavy Current Burst!
...
The Lightning Release jutsu from the Naruto world were replicated by Aoki using [Transmutation: Lightning].
The shape transformation involved would normally take over a decade of rigorous training to master.
But in the Gene Lock state, Aoki accomplished it effortlessly.
On the side.
Bisky was completely flabbergasted.
In her view, this was a combination of Transmutation, Manipulation, Emission, and Enhancement. (Enhancement can strengthen oneself, objects, and even cell activity to gain healing abilities—as seen with Kurapika in the original work)
This was the mystery of Linked Mountains!
"When I first practiced Linked Mountains, it took me several years just to get started..." Biscuit recalled her early days and was left speechless.
This Aoki had actually grasped the basics in just one day!!
Was this even fair?
Biscuit was utterly dumbfounded.
Linked Mountains refers to a cultivation method where one focuses on mastering one Nen category while supplementing it with two adjacent categories.
For example, an Enhancement-type Nen user.
They would primarily train in Enhancement while also practicing Emission and Transmutation, forming a "mountain"-shaped combat system.
Hence the name "Linked Mountains."
At the same time, Linked Mountains is considered a ticket to becoming a first-rate Nen user—a mark of true strength.
Just like mastering advanced techniques is a hallmark of elite Nen users.
"Don't look at me like that, Biscuit."
Aoki, having finished his training, sat down panting and entered a state of [Zetsu].
He had already used up all three of Miss Cookie's massages.
From now on, he'd have to endure the backlash on his own.
"My Nen ability specializes in learning techniques from all five major categories. Linked Mountains isn't that difficult for me," Aoki said.
Biscuit just scoffed. "Do you really think I'd believe that?"
If it were that easy, Linked Mountains wouldn't be called the gateway to first-rate Nen users.
Many Three-Star Hunters had only just grasped the basics of Linked Mountains.
Every single one of them had trained for decades.
Meanwhile, Aoki had only practiced for a single day.
This absurd speed was enough to make veteran Hunters want to bash their heads against a wall.
"Fine, I'll pretend you believe me."
Aoki shrugged. "Since we're here, let's eat first."
"...Hmph!" Biscuit snorted, but her body obediently picked up the meal box.
This was a specially prepared dish made by a Gourmet Hunter using Nen.
It had miraculous effects—boosting training efficiency, restoring stamina, and replenishing aura.
Of course, the effects weren't overwhelming.
But Aoki, being the wealthy man he was, ate five specially prepared meals a day.
Over time, the growth of his aura became substantial.
Both his manifested and latent aura were rapidly increasing.
"Your current aura reserves are among the top even for Two-Star Hunters," Biscuit remarked.
Since the custom-made meals included a portion for her, she could tolerate Aoki's lack of reverence.
"Is that so?"
Aoki listened with a calm expression, not particularly moved.
Originally an ordinary person, his physique had been weak.
But in the world of Hunters, humans could achieve superhuman physical capabilities.
Before Gon even learned Nen, he used a fishing rod to lift the Master of the Swamp, which weighed over a ton, and pushed open a two-ton gate at the Zoldyck estate.
Absolutely ridiculous!
However, after mastering Nen, Aoki's physical abilities had also been growing rapidly.
Especially with the unique dishes prepared by Gourmet Hunters using special ingredients.
Each bite transformed into a warm current, nourishing his entire body.
Aoki's weaknesses were being swiftly compensated for.
...
Night fell.
After a full day of training, Aoki returned to his hotel to rest.
Biscuit went to the Association's headquarters.
Finding a secluded spot, she dialed Chairman Netero's number.
Ring...
The call connected quickly.
"How's the training going, Biscuit?" Netero's cheerful voice came through the phone.
"It's going too well!"
Biscuit exclaimed excitedly, "Can you believe it? He mastered the basics of Linked Mountains in just one day!"
On the other end of the line...
Netero froze in astonishment, saying, "Wait, weren't you supposed to teach him to develop his unique Nen ability? How did it become Linked Mountains?"
"Oh, by the time I arrived, he'd already developed his Nen ability," Bisky replied flatly.
She was completely numb to it now.
Pfft!
Meanwhile, Netero nearly spat out his tea.
"He developed it already?"
"That's too fast!"
"It's only his second day since awakening Nen!"
Netero's voice was full of disbelief.
Bisky sighed. "I couldn't believe it either, but he truly mastered Linked Mountains from scratch right in front of me."
Netero fell silent.
His usually calm and carefree expression rarely showed surprise, but now it did.
First day: Awakened Nen, self-taught the Four Major Principles + advanced techniques, killed one of the Royal Guards, Neferpitou.
Second day: Developed a unique Nen ability, mastered Linked Mountains.
Was this even human?
Netero rubbed his temples, feeling a bit overwhelmed.
In his memory, humans weren't supposed to be this monstrous.
"Old man, at this rate, he might surpass you in less than a year and become the world's strongest Nen user," Bisky joked.
"Haha, that would be a good thing," Netero laughed heartily.
"It really would be," Bisky joined in the laughter.
He was always happy to see the younger generation grow.
Even if their views or stances differed, as long as it didn't harm humanity, he could accept it.
"What type is his Nen ability?" Netero asked.
"Specialist."
Bisky answered, "It's called 'The Complete One.' The effect is to negate the usual drawback of Specialists struggling to learn other Nen types, allowing him to master and develop abilities from all five other categories."
Netero listened, his expression momentarily dazed.
The Complete One?
It eerily aligned with some of his own theories.
"Chairman?" Bisky called when she didn't get a response.
"Ah, just lost in thought," Netero chuckled. "Anyway, Aoki's ability is quite fascinating."
"Trading the present for nearly limitless potential in the future."
"With his talent, he might become a super Nen user proficient in all categories."
Bisky nodded in agreement. "That's what I think too."
After discussing the situation in the NGL for a bit, they ended the call.
