SSS-Ranked Summoner: Only I Summon All Heroes And Heroines Of Legend-Chapter 39: Progress To Power (Timeskip Part 2)

Svenja’s Progress

Svenja stood completely still in her training section, her two orbs hovering before her.

For weeks, Master Oz had studied them obsessively. Running diagnostics, casting analysis spells. Muttering to himself as he pored over data that only he could interpret.

Finally, he’d given her his conclusion.

"Your orbs, I’ve never seen or heard of anything like it existing as a summon. One orb is a black hole, a point of infinite gravity that pulls everything in and destroys it. It is a "sink" where time and matter end in total extinction."

He continued.

The other orb is like a white hole, the mathematical opposite. It is a "fountain" that constantly pushes matter and energy out, acting as a source of pure creation where nothing can enter.. Whoever designed them understood principles most mages will never comprehend in their entire lives. This is a milestone in magical-science."

He’d paused, studying her carefully.

"Alas, they’re rigid. Right now, they only exist as spheres. Which makes them quite limited."

Svenja had tilted her head slightly—her version of a question.

"SHAPE, svenja..."

"What if you could change their shape?" Oz had asked. "Flatten them into discs for cutting, expand them into barriers. manipulate their shapes precisely to fit whatever task that is required. Keep their inherent properties constant, but alter the form it takes. This simple yet not simple task, will take you levels unimaginable."

And so the training began.

At first, nothing happened.

Svenja would stand there for hours, staring at her orbs, willing them to change shape, the same way she willed their movements.

They remained stubbornly spherical.

But she was patient. Methodical. She approached the problem the way she approached everything—with cold, analytical precision.

She experimented with different mental commands. Different visualizations, while altering the way she channeled her mana into the orbs.

And eventually, after two weeks of silent, relentless effort, one of the orbs bulged.

Just for a fraction of a second, its perfect spherical symmetry distorted.

Master Oz, watching from the edge of the field, had smiled. "Good. Again."

Progress came in millimeters.

And after a length of time, the orbs learned to flatten into razor-thin discs that could slice through stone like paper.

They learned to expand into concave shields that deflected incoming attacks.

They learned to elongate into spear-like projectiles that could pierce armor.

And by the end of the three months, Svenja’s control had become terrifying.

She could shift the orbs’ forms mid-flight, adapting to threats in real-time. She could create cutting edges, crushing barriers, piercing strikes—all from the same two constructs.

Her versatility had increased exponentially.

And though her expression never changed, Master Oz thought he detected the faintest hint of satisfaction in the way she moved.

"You’ve done exceptional work," he told her during their final session. "But don’t stop here. There’s more potential in those constructs than even I can fully understand. Your mind is at the peak of human potential, do not limit your imagination."

Svenja gave her usual minimal nod.

Finn’s Progress

Finn collapsed onto the stone floor of his training zone, gasping for breath.

His entire body felt hollow. Drained. Like someone had scooped out his insides and left nothing but an empty shell.

"Get up," Master Oz said calmly.

"I... can’t..." Finn wheezed.

"You can. And you will." Oz ordered.

Finn groaned, but forced himself upright on trembling arms.

The training was brutal in its simplicity.

Master Oz had placed seals on Finn’s back during their first session—black patterns that spread across his skin like living tattoos. One seal acted as a catalyst, helping him absorb ambient mana from his surroundings. The other was a stabilizer, preventing the absorbed energy from tearing him apart from the inside.

"Natural mana is wild," Oz had explained. "Unrefined, and dangerously chaotic. Your body isn’t designed to process it directly. These seals will help, but you still need to learn control, and discipline."

So Finn sat with his eyes closed, meditated, And desperately, yet carefully.

At first, he felt nothing.

Then, gradually, as his concentration improved, he began to sense it—a subtle current in the air around him. A pulse in the earth beneath him. Mana existed everywhere, flowing through the world like an invisible river.

He reached out mentally, trying to draw it in.

The first attempts were disasters. The mana slipped through his grasp like water through a sieve. Or worse, it flooded into him too quickly, making him nauseous and dizzy.

He’d, have been hospitalized. Or worse, dead. But the seals were his insurances. Master Oz as the last Oz, was indeed a master of everything.

With time, Finn learned.

How to be one with the world and access it’s energy rather than seek to demand it.

He worked on his internal balance, the way to regulate the flow so it didn’t overwhelm him.

By the second month, he could absorb a steady trickle. Enough to extend his reserves by a few minutes during combat.

By the third month, the trickle had become a stream.

His mana capacity didn’t just grow—it exploded.

"Good," Master Oz said, actually sounding impressed. "You’re beginning to understand. Your summon is powerful, Finn. Extraordinarily so. But power without fuel is meaningless."

He stepped closer.

"When you manifest it in true combat, you’ll need every drop of mana you can get. Keep training this technique. Make it a second nature. Let it run in the background of your consciousness at all times."

Finn nodded, still catching his breath.

The World Outside

While they trained in the pocket domain, the Academy made its decision.

Two weeks into their intensive training, an official announcement was distributed to all students:

---

OFFICIAL NOTICE

Due to ongoing security evaluations and infrastructure improvements, all remaining academic activities for the current term will be conducted remotely via online courses and virtual instruction.

Students may choose to remain on Academy grounds or return home. Those who remain will continue under the enhanced security protocols and strict curfew enforcement (dusk to dawn).

In-person activities will resume one week prior to final examinations.

—Administration of Gran-Lusia Academy

---

The announcement sent ripples through the student body.

Some left immediately, eager to escape the unsettling atmosphere that had grown over the campus since the summoning plane incident.

Others stayed, unwilling to abandon their studies or too proud to show fear.

Altair, Ryka, Svenja, and Finn stayed.

And they kept training.

Master Oz’s pocket domain became their second home. The outside world faded into background noise—assignments completed in spare moments, virtual lectures half-listened to while recovering from brutal training sessions.

Days faced paced into weeks.

Weeks into months.

They pushed past limits they didn’t know they had. Broke through barriers they’d thought were permanent.

And slowly, steadily, they transformed.

---

The Final Day

Three months after they began, Master Oz called them all together.

The four barriers dissolved, merging back into a single open space. Altair, Ryka, Svenja, and Finn stood in a line, facing their teacher.

They looked different now.

Altair stood with quiet confidence, the ring on his finger gleaming faintly. Ryka’s eyes carried a sharper focus, her entire posture reflecting her bond with Rhegalyion. Svenja stood calm as usual, but even a casual could sense her aura had amplified. And Finn, though still lean, radiated a strength that hadn’t been there before.

Master Oz studied them for a long moment.

Then he nodded.

"You’ve done well," he said simply. "All of you. You came here with potential, but you were still greatly unprepared."

He gestured at them.

"Yet now... now you might actually survive what’s coming."

Altair felt a flicker of pride.

"But," Oz continued, his tone sharpening, "training is one thing, and Application is another."

He raised one hand, and the pocket domain began to shift.

The smooth stone floor cracked and buckled. Pillars of rock erupted from the ground, creating a maze-like terrain. The sky above darkened, swirling with storm clouds that rumbled ominously.

"Your final test," Oz said, "begins now."

The four of them tensed immediately.

"What kind of test?" Ryka asked.

Master Oz smiled.

It wasn’t a comforting smile.

The kind that meant "show me whether you’ve truly learned anything."

He stepped back, and all three clones began to fade into shadow.

"Each of you will face an opponent," he said. "One that will test everything you’ve developed over these three months."

The storm above them roared to life, lightning crackling between the clouds.

"And if you fail..." Oz’s voice echoed.

"...you will understand exactly how far you still have to go."

For a moment, there was only silence.

Then.

Master Oz formed a strange seal, nothing similar to what they’ve seen all through their training.

"Devil’s Phantasm: Mirror of Heaven and Earth"

The words echoed from everywhere, triggering the group to adjust their stance.

"Get ready" Altair muttered.

But as they all blinked, their eyes snapped to a different view.
