Two days had passed since Harry Potter arrived at Hogwarts, and in those two days, the castle itself seemed to bend subtly around his presence. While most first-years were still adjusting to shifting staircases, talking portraits, and the overwhelming freedom of magical education, Harry had immersed himself completely in books, theory, and practice.
The library had become his second home, its shelves yielding knowledge at a pace that left even Ravenclaws quietly unsettled. In just forty-eight hours, Harry had earned forty house points entirely by himself, outperforming students not only from his own year but even several upperclassmen.
Gryffindor House whispered his name with pride, amazement, and growing reverence. He was no longer just The Boy Who Lived—he was becoming something else entirely. A prodigy. A rising star. A force.
Yet academics were only one aspect of his growth. At night, when the castle slept and prefects patrolled lazily, Harry moved through Hogwarts like a ghost. Using the enchanted Hogwarts Map he had acquired earlier—a map similar in spirit to the Marauder's Map but vastly superior in scope—he explored secrets long forgotten. The parchment revealed not only the movements of every student and professor within the castle but also countless hidden rooms never mentioned in books or films.
Ancient laboratories, sealed vaults, forgotten shrines, collapsed passages, and even the unmistakable marking of Salazar Slytherin's Chamber of Secrets were all laid bare before his eyes. Among these, one location called to him most strongly: the Room of Requirement.
Under the veil of a Disillusionment Charm, guided by both the map and the Compass of True Desire, Harry slipped through the corridors late at night. The castle shifted and groaned softly around him as he reached the blank stretch of wall on the seventh floor. He slowed his steps, clearing his mind, focusing his intent. A place to train. A place to grow stronger. He walked past the wall once. Twice. Three times. Then the stone rippled, reshaped itself, and a door materialized seamlessly from the wall. Harry did not hesitate. He opened it and stepped inside.
The Room of Requirement answered perfectly. The interior was vast, its ceiling high and shadowed, the air heavy with magic. Dozens of humanoid training puppets stood arranged across the space, each gripping a wand, their wooden faces blank and unfeeling.
This alone would have been more than enough for most students, but Harry had something else in mind. Reaching into his system inventory, he pulled out a small capsule and tossed it onto the floor. The moment it made contact, it expanded violently, unfolding and reshaping itself into a massive spherical chamber that nearly touched the ceiling of the room.
Its surface gleamed with unfamiliar materials, humming faintly with power.
Harry opened the chamber and stepped inside. What greeted him was not a magical training room, but something far more advanced—a full gym, filled with equipment utterly alien to his era. Heavy resistance machines, weighted platforms, energy conduits, adjustable gravity fields, and reinforced training zones stretched out before him.
At the center stood a control panel lined with levers, switches, and glowing buttons. Resting atop it was a thick book simply titled Manual. Harry opened it and read the entire thing in one sitting, his Hyper Mind absorbing and organizing every detail instantly. When he finished, understanding settled over him completely.
The chamber was a controlled enhancement environment, capable of altering gravity, resistance, atmospheric pressure, and energy flow to accelerate physical and magical development.
Without hesitation, Harry adjusted the gravity to twice the normal level.
The moment the setting took effect, his body slammed downward as if the world itself had grown heavier. His knees bent, muscles screaming in protest, his breath forced from his lungs. For a brief moment, even Harry was stunned by the pressure.
Then he steadied himself, clenched his fists, and adjusted his stance. Slowly, deliberately, he adapted. He began to train. He exercised relentlessly, pushing his body through brutal physical routines, then practiced mana circulation under pressure, forcing his magic to flow smoothly despite the crushing force.
He transitioned into Serpent Breathing, each inhale and exhale precise, controlled, perfectly synchronized with his body's movements.
Finally, he practiced Renewal Taekwondo, executing techniques that strained every fiber of his being.
Four hours passed in relentless effort. When he finally disengaged the gravity field, the sudden lightness made him stagger. His body felt unreal—stronger, faster, more responsive. Power surged beneath his skin. The results were undeniable.
Satisfied, Harry exited the chamber, pressed the control switch, and watched as the massive structure collapsed back into a compact capsule.
He stored it inside his ring, left the Room of Requirement under Disillusionment once more, and returned quietly to his dormitory to freshen up as if nothing had happened.
During these two days, Harry had also formed an unusual routine with the Hogwarts house-elves. Sneaking into the kitchens, he worked alongside them, preparing meals not only for himself but also for Sparky and Hedwig. One night, he cooked meat harvested from a Sea King, rich with dense life energy.
The effects were immediate. The moment they ate, all fatigue vanished, muscles revitalized, magical exhaustion erased. Hedwig, already transformed by the Frostwing bloodline, began to grow. From her previous three-foot height, she expanded further, reaching nearly four feet tall—an enormous owl by any standard.
Sparky's transformation was even more dramatic. The small Pokémon grew several inches, faint arcs of electricity dancing constantly around his body. When Harry asked what had happened, Sparky squeaked proudly, and understanding clicked instantly. Thunderbolt. A move Pichu should not have been able to learn yet. Hyper Mind analyzed the phenomenon immediately.
The Sea King meat's energy had accelerated Sparky's growth by nearly twenty levels. Harry and Hedwig, possessing bloodlines, had only gained minor enhancements. Sparky, lacking any bloodline but being a Pokémon, had benefited massively.
The following morning, Harry headed to the Great Hall. Hermione and Neville joined him soon after, and the three talked quietly as they ate. It was Friday. Their schedule included Defense Against the Dark Arts with Ravenclaw and a double Potions class with Slytherin. Using the Compass of True Desire, Harry led them efficiently through the castle. When they entered the Defense classroom, they found Professor Quirrell seated stiffly, muttering to himself.
The moment he noticed students arriving, he straightened abruptly, eyes darting nervously—especially toward Harry. The stench of garlic filled the room so strongly it made several students grimace.
The lesson itself was dull. Quirrell stuttered through textbook passages, offering nothing of value. Still, Harry answered question after question flawlessly, earning fifteen points. He ignored the way Quirrell watched him from the corner of his eye.
At lunch, Hermione complained. "That class was awful. He didn't teach us anything useful."
"We'll practice on our own," Harry replied calmly. "Theory is meaningless without application."
Hermione nodded eagerly. Ron, who had joined them, looked uninterested. Neville wanted to speak but hesitated. Harry noticed—and said nothing.
Potions was next. Harry sat beside Hermione, Ron with Neville. When Professor Snape entered, his presence alone silenced the room. His lecture followed the same biting tone as in the books. Then his gaze fixed on Harry. "Potter," Snape drawled. "Tell me what I would get if I added powdered root of asphodel to an infusion of wormwood."
Harry met his eyes directly and answered without hesitation. Question after question followed, and Harry answered them all. Snape saw Lily's eyes looking back at him—sharp, intelligent, unyielding.
He turned away abruptly without awarding points.
During brewing, Neville made a disastrous mistake. The potion reacted violently. As it tipped toward Neville, Harry thrust his hand forward. The potion froze mid-air. Snape spun around, furious—then saw Harry's cauldron. Perfect. Flawless. Pure. His anger stalled. Against every instinct, Snape forced out, "Five points… to Gryffindor." The room erupted in shock.
After class, Harry stayed behind. "Professor, may I speak with you?"
Snape sneered. "What could you possibly want?"
"I also regret my mother's death," Harry said calmly. "And I intend to kill Voldemort. I want your help. Can you be my mentor."
Snape froze. "Explain yourself."
"I saw you holding her when she died. You cried for her and you even took me to Headmaster Dumberldore."
Snape's voice dropped dangerously. "How do you know this?"
"My memories which were sealed or rather blured were awakened with my magic."
Silence followed. Then Snape ordered him out.
That night, Snape stood before Dumbledore, recounting everything. Dumbledore listened, troubled. "The choice is yours, Severus," he finally said. Snape left without answering.
Later, Harry sat in the library with Hermione, confident. He had made his move. Now he would wait.
And that night, when the castle slept once more, Harry rose again, slipping silently toward the Room of Requirement—toward power.
