SSS-Ranked Surgeon In Another World: The Healer Is Actually OP! Chapter 291: The Siege

Silence lingered in the throne hall. Not the silence of uncertainty or hesitation, the silence that follows a blade being drawn. Clean. Inevitable.

Then Isolde’s expression shifted.

Not political. Not strategic. Personal.

"There is sothing else," she said.

Duke’s gaze sharpened imdiately. Bruce turned fully toward her, reading the subtle change in her posture. This was no longer about infiltration across kingdoms. This was closer.

"My possession did not occur randomly," Isolde continued. "It began years ago. Before the Guild suppression. Before the isolation policies."

She descended from her throne once more. Frost trailed faintly behind her boots, but it did not surge. It followed her like a mory.

"There was an anomaly. Near the northern border." Her voice steadied into the cadence of a report, though the weight beneath it was anything but clinical. "A Labyrinth that spawned under unusual circumstances."

Duke frowned. "Unusual how?"

"It did not follow standard mana fluctuation patterns. There were no preliminary dungeon formations. No gradual rise in ambient density. No warning signs." Her eyes grew distant for a mont. "It simply appeared."

Bruce exchanged a brief glance with Duke. The sa thought passed between them unspoken.

Not natural. A forced insertion.

"I personally went to investigate," Isolde continued. Her jaw tightened faintly. "That was my mistake."

The hall seed to grow colder, not from frost, but from the weight of rembered miscalculation.

"When I approached the entrance, I sensed sothing wrong. The mana flow was stable. Too stable. Artificially balanced." She paused. "I realized too late."

Bruce watched her carefully, noting the restraint in her voice. This was not a woman recounting tragedy. This was a sovereign dissecting a tactical failure.

"The Invader ambushed ," she said calmly. "Not physically." Her fingers brushed lightly against her temple. "Soul-first, I posed no resistance to it."

Duke’s expression hardened.

"It attacked in proximity to the Labyrinth," she continued. "Using it as an anchor."

"A prepared foothold," Bruce said quietly.

"Yes." Isolde nodded. "The Labyrinth was not rely a dungeon. It was infrastructure."

A heavier silence settled over the throne hall.

"After it possessed ," she went on, "it did not clear the Labyrinth. It bypassed the outer layers entirely and went directly to the Core."

The words landed like falling ice. Bruce felt the implication before it was spoken.

"Claid it," Duke said flatly.

"Yes." Her voice did not waver. "Through the Core, it established dominion over every beast within the Labyrinthine space."

Bruce exhaled slowly, his mind already calculating the consequences. "And then?"

Isolde’s eyes darkened. "It began feeding."

Duke’s fingers tightened where they rested against his arm.

"Surrounding dungeons," she continued. "Over the years. Absorbed. Devoured." Each word carried the weight of years unnoticed. "The Labyrinth expanded. Its territory increased. Its internal mana density rose. The beast population multiplied beyond natural projections."

"A growing ecosystem," Bruce said.

"A controlled army," Duke corrected.

Isolde nodded. "The Core was used to annex lesser dungeons and incorporate their space. Their creatures were either assimilated or consud. Their mana redirected."

"And no one suspected?" Duke asked.

"They suspected growth," she replied. "An unusually prosperous Labyrinth. Increased drop quality. Higher-tier beasts." Her lips thinned. "But not orchestration."

Bruce leaned forward. "How large is it now?"

"Several tis its original size."

Duke let out a slow breath as Isolde continued...

"And now?" Isolde’s expression tightened. "The Core is soul-linked to the Invader. Which ans,"

"Now that the Invader is gone," Bruce finished, "the link is destabilizing."

"The beasts are losing centralized control," she confird.

Duke straightened. "They’re going berserk."

"Yes. They are still confined within the Labyrinth." She held his gaze. "For now."

Bruce’s jaw tightened.

An unnaturally vast Labyrinth. An overpopulated ecosystem. Mana saturation at abnormal levels. No governing will. A powder keg with a lit fuse and no one holding the match.

"If containnt fails?" he asked.

"They will spill into Eiskar," Isolde said calmly. "Not as scattered threats. As a wave."

The throne hall seed smaller suddenly, the walls pressing inward with the gravity of what she described.

Duke broke the silence. "What do you intend to do?"

Isolde lifted her chin, frost steadying beneath her. "I will go to the Core. And claim it."

The words did not tremble.

"I will sever the residual soul-link and establish my own authority over the Labyrinth."

Duke studied her. "You’re confident you can dominate it?"

"I am the rightful sovereign of this territory," she replied evenly. "The Labyrinth was born within my domain. Its anchor lies in my land while that alone is not enough."

Sothing colder moved through her expression, not cruelty, but pragmatism honed to a razor’s edge. "And the Invader and I shared the sa body for years. The Core will recognize the mana signature of its forr master. That resonance gives an opening no one else would have."

Bruce’s gaze did not waver. "And the beasts?"

Her answer ca without hesitation. "That is why I need you."

Duke’s lips curved faintly. "There it is."

Isolde turned fully toward them both, all pretense stripped away.

"I cannot fight through an army of berserk high-tier beasts while attempting to claim the Core. The claiming process requires focus. Stability. Direct contact with the Core itself." Her eyes t Bruce’s. "If I am interrupted at the wrong mont, the backlash could shatter the Core, or ."

Bruce understood imdiately. "You want us to hold the line."

"Yes. Restrict them. Contain them. Buy ti."

Duke rose slowly to his feet, the casual air around him thinning into sothing sharper. "How many are we talking about?"

Isolde did not hesitate. "Thousands."

The word echoed faintly in the vast hall.

"Many have grown beyond their original ranks due to prolonged Core feeding," she continued.

"High-tier variants. Mutated evolutions. So may approach SSS thresholds within the Labyrinth’s environnt."

Duke exhaled through his nose. "So this isn’t a dungeon raid."

"No," Isolde said. "It is a siege. But those beasts will be an important force for Eiskar’s future, which is why I must take the risk. If I can gain control of them, we don’t just neutralize a threat. We gain an army."

The frost beneath her pulsed once, slow and deliberate.
