Hisoka had already tasted the sweetness of increased nen after death.
No matter who survived between him and Illumi, they would both evolve. And what was Hisoka's ultimate goal? To sublimate his Nen once more, to get closer to the level of Halo.
Illumi was just a stepping stone.
As for Illumi himself, he was also hungry for power. If he could awaken the thought of the afterlife and shatter the shackles of his own potential, his future heights would soar far beyond the reach of ordinary men.
Illumi had undoubtedly realized how abnormal Killua's talent truly was. Under normal circumstances, Killua could surpass him in just a few years, but Illumi, with his strong sense of responsibility as the eldest brother, felt that he alone could protect his family and uphold the Zoldyck name. In his mind, Killua would always be just a younger brother.
Therefore, he too had to find ways to become stronger.
To reach the level he and Hisoka were striving for, every step forward was difficult beyond measure; significant improvements did not come easily.
Awakening the thought of the afterlife wasn't easy; it required the will of both fighters to gradually increase as the battle progressed, reaching an explosive peak before opening at the precise moment of death! Both the timing and the target had to be chosen perfectly. It wasn't something you could achieve by simply picking any opponent.
One had to be genuinely interested in the fight, and both parties had to possess an extraordinary level of skill.
If an opponent didn't interest you, no matter how fierce the battle, your personal will wouldn't fluctuate with enough intensity and you would simply feel bored.
This explained why Hisoka had awakened the thought of death while fighting Chrollo, because he'd enjoyed it, relished it, completely immersed himself in it!
Certain emotions and psychological states served as nourishment for Nen; without them, his Nen could never break through.
At the cost of one's own life, it was extreme, but effective.
They had both seen through the essence of Nen and understood how to play with it. Then Oboro rose and left to find Wing.
After finding the room number where Wing and the others were staying, Oboro knocked on the door.
Moments later, the door opened.
Standing in front of Oboro was a boy in a small white training suit who looked well-behaved and attentive.
His eyebrows were slightly thick, giving him a childish yet endearing look.
Unlike Killua and Gon.
Gon's aura was pure and gentle, while Killua's was that of a dark, clever ghost "Hello, who are you looking for?" Zushi looked at the man in the black suit standing in front of the door and asked politely.
"You're Zushi, right? Wing's apprentice," Oboro smiled.
"Osu!"
Seeing that this man seemed to be a friend of his master, Zushi immediately lowered his fist and bowed his head respectfully.
Since he is the friend of the master, he must be a senior, Zushi thought.
"Oboro?"
Just then, Wing heard the voices and stepped into the corridor. When he saw Oboro, surprise crossed his face.
Although he had communicated with Oboro and had mentioned Gon and Killua, he also knew that Oboro was busy and he hadn't expected him to actually come to the Heaven's Arena in person.
"Oboro?"
Zushi's eyes widened, his face filled with awe.
During this time, he had heard his master and Gon mention this man's name so many times that his ears had become numb. All he understood was that Oboro was immensely powerful, unimaginably powerful.
"Ah! It's Mr. Oboro!"
Then Oboro heard Gon's familiar voice call out in surprise.
There was also Killua, drenched in sweat, with half of his head sticking out. After he saw that the visitor was Oboro, his expression became noticeably sour.
"You're all working really hard!"
Oboro patted Zushi on the head, walked in, saw Gon running up to him drenched in sweat and praised him.
"Are we disturbing you?"
"Not at all."
Gon shook his head.
"Last time at the hotel, I said I'd come back to visit when I had time. Did you think I just said that casually?" Oboro walked into the living room and patted Wing on the shoulder.
Wing smiled weakly.
"How is it going? How far have you both gotten with your training?" Oboro sat down on the couch and looked at Gon and Killua.
"Master Wing is teaching us the Nen technique of 'Ren'," Gon said excitedly.
Killua, who was standing nearby, looked at his good friend and couldn't complain. He clearly sensed that whenever Gon saw Oboro, the boy's mood brightened considerably and his emotions shifted noticeably, it was different from how he treated others.
Show-off,' Killua grumbled in his mind.
"Oh? How good are you? Do you mind if I try?" Oboro asked happily.
"Sure!" Gon nodded vigorously, seemingly eager to demonstrate his progress in front of Oboro.
He called the reluctant Killua and Zushi over, and the three of them stood side by side.
Though Killua said nothing, the white-haired boy seemed to harbor a desire to show off, impressed by their rapid progress. After all, Wing had mentioned that their comprehension and growth rate were particularly astonishing.
Oboro, who was not wearing his sunglasses, carefully examined the aura of the three young men.
Indeed, it was a bit frightening.
The differences were obvious in this comparison: Zushi's energy seemed relatively scattered. Despite his best efforts to control it, traces of aura still leaked out. Gon's and Killua's auras, on the other hand, were already showing signs of becoming "sticky," exactly what experienced Nen users called "thick" during their basic training.
A person with an innate talent for Nen found it easier to control their aura, which was primarily related to the mind. Better control meant less energy leakage, resulting in an aura that flowed smoothly and remained tightly wrapped around the body. At the same time, the physical life force corresponded to the amount of energy; the more energy present, the thicker the aura. When both aspects were exceptional, the true density of Nen was revealed.
This was a promising sign.
The critical point was: how long had Gon and Killua been training in Nen with Wing? For an ordinary person, it would take at least a year to reach this level, and that was for those with above-average talents.
After watching for a while, Oboro couldn't help but clap his hands and exclaim in astonishment: "Incredible!"
Actually, he wasn't surprised at all.
He knew these two little monsters all too well.
"Isn't it something?" Wing echoed. "If they continue to gain good experience and develop properly, compared to your strength when you first came to the sky arena, I'm afraid they might be" "Hehehe! Scared now? I've noted our differences, and I'll keep them in mind. One day, I'll settle things with you!" Killua suppressed his irritation and rubbed his nose with his fingers, looking smug and thoroughly pleased with the expression on Oboro's face.
"Gon and I are very strong, don't underestimate us!"
"Killua," Gon laughed awkwardly.
"What are you talking about?" Oboro stared at the white-haired boy with a playful expression. "I was praising Zushi for doing such a good job, I didn't say anything about you. As a member of the Zoldyck family, isn't it normal for you to reach this level? You're also known as the most talented person in your family," "Or could it be that you're already complacent and satisfied with just this little bit of progress?"
Oboro's words immediately made Killua's cheeks flush and he replied angrily: "Of course not!"
"That's good."
Oboro nodded. "You and Gon are special, it's expected that you've mastered the basics of Nen to this level in such a short time. I don't know what Wing has told you, but in my opinion, it's not enough, not nearly enough. Zushi, on the other hand, is not too far behind you two, which means that he has surpassed both of you in sheer effort. I appreciate this mentality even more."
Zushi's face froze. He hadn't expected Senior Oboro to praise him, which left him speechless for a moment.
He could only mutter an "Oh" and bow to Oboro in gratitude.
Gon looked serious and took Oboros words to heart.
After that, Oboro stood up and said to Wing, "Let's go. We haven't seen each other for a long time. Let's take a walk."
Wing looked at the three young people in the room, smiled and waved his hand. "Don't think too much about what he said, just keep practicing."
Then he promptly left.
As he closed the door behind them, Wing hesitated for a moment, glancing at Oboro.
The eyes behind the glasses narrowed.
Although he had a good relationship with Oboro, one thing remained certain: he didn't want Gon and Killua to become people like Oboro.
Therefore, he hoped that Oboro's thoughts and actions wouldn't influence Gon and Killua.
Otherwise, with the potential these two had shown so far, they might end up becoming the same kind of person as Oboro, which would be too tragic!
He wanted to keep Gon and Killua as far away from his friend as possible.
Relations were relations, feelings were feelings. Wing felt that some of Biscuit's judgments about Oboro were still quite accurate.
The person named Oboro himself symbolized danger and instability.
