Heavens Arena, 200th Floor, Room 2079.
Leo sat cross-legged in the center of the training room, eyes slightly closed, his breathing steady and long.
Nen lingered around his body like a thin mist, flowing slowly with his rhythmic breathing.
Seven days had passed since that hearty sparring match with Wing. During this time, aside from participating in one match, he spent the rest of his time consolidating the Four Great Principles.
"Knock, knock, knock."
The sound of knocking echoed with a light rhythm.
Leo opened his eyes, and the Nen withdrew into his body.
He stood up and walked to the door. The moment he grasped the handle, his movements paused slightly—the aura coming from outside was very special, solid and restrained, yet as vast as the deep sea.
He pulled the door open.
Standing outside was a blonde girl with twin tails.
She wore an exquisite pink princess dress, with slender wrists peeking out from under lace cuffs. Her large pink eyes blinked, and a perfectly placed shy blush colored her face.
"Hello, Mr. Leo."
The girl's voice was crisp and pleasant. She folded her hands in front of her, looking quite timid.
"I'm a fan of yours. Your matches are so exciting! Could I... could I have your autograph?"
The hair on Leo's neck stood up, and a layer of cold sweat instantly broke out on his back.
The "girl" in front of him was undoubtedly Biscuit herself—that face as exquisite as a doll's, those eyes that seemed innocent yet were bottomless, and that signature princess dress.
Her mischievous streak was acting up.
Leo knew very well that exposing her disguise to her face would be seeking death. Especially when she was having so much fun.
"H-Hello!"
Leo forced a smile, his voice sounding a bit dry.
He felt Biscuit's gaze scanning him unscrupulously—it wasn't the look of a fan watching an idol, but the look of a Hunter scrutinizing prey.
He took a deep breath, forcing himself to relax, and the corners of his mouth curved into a more natural arc.
"It's my honor to have such a beautiful Young Miss like you as my fan."
A hint of playfulness flashed in Biscuit's eyes.
The moment the door opened, she had captured the subtle fluctuations in Leo's eyes and expression—that instant of surprise, though quickly masked, did not escape her eyes.
This kid knows me.
Biscuit instantly lost interest in continuing the act.
She shrugged and naturally squeezed past Leo into the room, her skirt brushing against the doorframe.
"Your acting is too poor; it's no fun."
Her voice was still that of a crisp young girl, but her tone had changed, carrying a sort of condescending casualness.
"Speak up, what's the commission? My time is very valuable."
Leo closed the door, a perfectly timed look of embarrassment on his face as he turned around.
"I'm sorry, Sister Biscuit, for spoiling your fun."
He picked up a small velvet pouch from a nearby cabinet, untied the string, and poured out a pigeon-egg-sized red gemstone.
The gem refracted brilliant light under the indoor lamps, its internal flame-like patterns seemingly rotating slowly.
"This is the reward for the commission."
Biscuit's attention was instantly captured by the gem.
She took the 'red storm,' holding it in her palm to examine it closely, her blue eyes shining remarkably bright.
"Pure color, perfect clarity, and the cut is a Great Master's handiwork... the internal storm patterns are naturally formed, every wisp of flow is unique."
She murmured to herself, sounding as professional as a jewelry appraiser.
A moment later, she looked up, her face showing unmasked excitement.
"It's truly beautiful! As expected of the red storm!"
Biscuit rubbed the gem against her cheek, looking intoxicated.
"From now on, I'll call you Little Red-Red!"
Leo watched this scene and felt a secret sigh of relief—playing to her interests was the right move.
Biscuit played with the gem for a while before putting her attention back on Leo.
She walked up to Leo, looking up at the young man who was a head and a half taller than her.
"I know that besides being strikingly handsome, your strength is also quite formidable."
Leo bowed slightly, his tone sincere.
"I would like to ask you to guide my Cultivation for a period of time. I wonder if it's convenient?"
Biscuit didn't answer immediately.
She had already seen Wing before coming here and had gotten a general idea of Leo's situation from her disciple—formidable strength, a clean and efficient fighting style, and already two wins on the 200th floor.
"Regarding Nen, how much do you know? How long have you been Cultivating?"
Biscuit asked, her eyes still fixed on the gem.
"Regarding Nen, I basically understand the System. As for the duration of Cultivation..."
Leo paused.
"Less than two months."
Biscuit's fingers paused slightly.
She put down the gem, turned around, and began to observe Leo seriously.
Those pink eyes were now as sharp as knives, as if they wanted to pierce through flesh to see every detail of his bones and Meridians.
Leo stood calmly, letting her scrutinize him.
His breathing was steady, and his gaze was candid.
Only two months of Cultivation?
Biscuit was secretly shocked.
She could feel a solid foundation from Leo, but judging by his aura alone, he far surpassed a typical beginner.
More importantly, this body—the muscle lines were perfect, every inch containing explosive power.
There were many faded scars on his skin, evidence of having experienced countless actual battles.
He could reach this step in just two months?
Either he was a natural monster, or... he had a special opportunity.
Biscuit leaned toward the latter.
There are no shortcuts in Nen Ability Cultivation; even the highest talent requires time and sweat.
But she also understood that there are always existences in this world that exceed common sense.
"Since you are so sincere..."
A moment later, Biscuit spoke, a satisfied smile appearing on her face.
"I'll take this commission."
Leo's eyes lit up, and he bowed solemnly.
"Thank you very much."
He straightened up, walked to a cabinet on the side, pulled open a drawer, and took out several exquisitely packaged booklets.
The covers of the booklets were glossy art paper, reflecting slightly under the light.
Biscuit's gaze swept over the covers—several shirtless men with well-defined muscle lines were presented in various tension-filled poses. Their abs, chest muscles, and biceps glowed healthily under the photography lights.
Her eyes instantly widened, and stars seemed to pop out of her pupils.
"This is a thank-you gift for you; please be sure to accept it."
Leo handed over the booklets.
Biscuit practically snatched them. She quickly flipped through a few pages, her eyes brightening with every page she turned.
"'Macho Man Fitness Diary'... 'Muscle Aesthetics'... 'The Combination of Power and Beauty'..."
She murmured the titles, the smile on her face growing more and more brilliant.
"Not bad! You even investigated what I like so clearly!"
Biscuit hugged the books tightly to her chest and looked up at Leo, her eyes full of appreciation.
"Good boy, I'm liking you more and more."
Leo smiled slightly.
Of course he knew—since he was asking for a favor, he naturally had to play to her interests.
Only by pleasing her would she guide him seriously.
"Alright, enough small talk."
Biscuit carefully placed the gem and the booklets on the table, her expression returning to seriousness.
"You're an Enhancer, right? Show me your 'Ren'."
Leo nodded, took a few steps back, and stood firm in the center of the training room.
He closed his eyes and took a deep breath.
The next second— "Boom!"
Nen erupted from Leo's body like a volcanic explosion!
White air currents instantly filled the entire training room, stirring the air and forming visible vortices.
Leo's hair and the hem of his clothes lifted upward, his entire body shrouded in a dense halo.
Biscuit crossed her arms and watched quietly.
Time passed minute by minute.
Five minutes, ten minutes, fifteen minutes... Sweat began to bead on Leo's forehead, and his breathing gradually became heavy.
The Nen halo around him remained stable, but the strain of maintaining it was evident.
Twenty minutes... Leo's body began to tremble slightly, his teeth clenched, and veins popped out on his forehead and neck.
Twenty-four minutes.
"Ha... ha..."
Leo finally couldn't hold it any longer, and the Nen receded like a tide.
He panted heavily, sweat dripping from his chin onto the floor, creating dark stains.
Biscuit's gaze was calm.
"Twenty-four minutes. Far from enough."
Her voice had no fluctuation.
"A qualified Nen User must be able to maintain it for at least half an hour. In battle, you need to use 'Ken' frequently, which requires even higher endurance for 'Ren'."
Leo wiped the sweat from his face and nodded while panting.
"However..."
Biscuit changed her tone, a hint of approval flashing in her eyes.
"You've only been Cultivating for two months. To reach this level is... passable."
She walked up to Leo.
"What about your ability? Can you show it to me?"
Leo adjusted his breathing and said slowly.
"I haven't developed an ability yet. I want to build a solid foundation first before considering the construction of a specific ability."
A gratified look appeared in Biscuit's eyes.
"Good, your thinking is very sound."
She stood up, hands behind her back, and began pacing the training room, her tone becoming like that of a lecturer.
"Enhancers don't really need to develop flashy ultimate moves. The physical body is an Enhancer's greatest advantage. As long as you Cultivate the Four Great Principles—Ten, Ren, Zetsu, and Hatsu—to the limit, you will be unstoppable in a head-on confrontation."
She stopped and turned to look at Leo.
"Of course, if you have special needs, you can also develop an ability. But remember, an Enhancer's ability is best when it's simple and direct. The simpler the Vow, the more effective it usually is."
Leo listened intently, committing these words to memory.
"I will guide your Cultivation well."
Biscuit walked to the table, picked up the gem and the books, and a smile returned to her face.
"As for how far you can go, that depends entirely on your own efforts."
She walked to the door and spoke over her shoulder before pulling it open.
"Pack your things. We leave Heavens Arena in three days."
Biscuit's gaze swept over this spacious but ultimately limited room.
"The venue here isn't quite suitable for your special training."
The door closed gently.
Leo stood in place, looking at the now-quiet room, a smile slowly spreading across his face.
The special training was about to begin.
He walked to the window and looked out at the crowds and vehicles flowing like ants below Heavens Arena.
This giant tower had witnessed his growth, and now, he was temporarily leaving for a broader training ground.
The dark red tattoo on the back of his hand glowed faintly under his sleeve.
[Rank: 27 (91%)] Just a little more to level up.
But more than the increase in Rank, the upcoming systematic Cultivation was the true key to solidifying his foundation.
Leo turned and began to pack his luggage.
He knew that Biscuit's training would definitely not be easy—he could guess as much from Wing's complicated expression.
But he wasn't afraid. No matter how hard or tiring, as long as he could become stronger, he would welcome it gladly.
