The moment they crossed the threshold, everything changed—not gradually, not subtly, but instantly, like stepping into a space that didn't follow the same rules as the rest of the world, because the air inside the hidden level was heavier, charged with a raw, unstable energy that made it hard to breathe properly, and the darkness wasn't complete—it pulsed faintly with dim, unnatural light coming from structures embedded into the walls, machinery that didn't look entirely mechanical, something more advanced, something experimental, something alive in ways it shouldn't have been, and as Zein Shoin moved forward slowly, she felt it stronger than ever, that undeniable connection, like every step she took was pulling her deeper into something that recognized her completely.
"…this isn't a lab," she said.
"No," Ace Craige replied,"…it's something else."
Zein looked around.
"…they were hiding this under everyone," she said.
"Yes," he replied.
"…why?" she asked.
Ace's voice lowered.
"Because no one would believe it existed," he said.
A low hum filled the space.
Growing louder.
Zein's breath slowed.
"…it's reacting again," she said.
"To you," Ace replied.
Zein didn't deny it.
"…yes," she said.
They moved deeper.
The structure opened into a massive underground chamber—
And at its center—
A core.
Pulsing.
Unstable.
Alive.
Zein stopped.
"…that's it," she said.
Ace's eyes narrowed.
"…that's not just energy," he said.
"…no," Zein whispered,"…it's something else."
The core pulsed again—
Sending a shockwave through the chamber.
Zein didn't flinch.
Ace stepped slightly in front of her.
"Stay back," he said.
"…no," she replied.
"Zein," he warned.
"I need to get closer," she said.
"You don't know what it'll do," he said.
"…I think I do," she replied.
Ace's voice hardened.
"That's not reassuring," he said.
Zein stepped forward anyway.
The energy reacted instantly—
Stronger.
Faster.
The entire chamber trembled.
"…it recognizes me," she said.
"That shouldn't be possible," Ace replied.
Zein's voice dropped.
"…I've felt this before," she said.
Ace went still.
"…when?" he asked.
Zein shook her head.
"…I don't remember," she said,"…but I know it."
The core pulsed violently.
Zein reached out—
Not touching it—
But close enough.
The energy surged toward her.
"…Zein, stop," Ace said sharply.
"I can't," she replied.
The energy wrapped around her—
Not attacking—
Responding.
Ace grabbed her arm instantly.
"Step back," he said.
Zein didn't move.
"…it's not hurting me," she said.
"That doesn't mean it won't," he replied.
Zein's voice softened—
But stayed steady.
"…it's not dangerous to me," she said.
Ace's grip tightened.
"…and that's exactly what makes it dangerous," he said.
Zein finally looked at him.
"…this was sealed," she said.
"…by who?" he asked.
Zein turned back to the core.
Her voice barely above a whisper.
"…by me," she said.
Silence.
Ace froze.
"…that's not possible," he said.
Zein didn't respond.
Because now—
She was starting to remember.
Fragments.
Feelings.
Control.
"…I didn't just seal it," she said slowly,"…I created it."
The core reacted violently—
As if confirming her words.
Ace stepped back slightly.
"…what are you saying?" he asked.
Zein's expression changed—
Not confused anymore.
Certain.
"…this isn't just energy," she said,"…it's power that was never meant to exist."
Another shockwave exploded outward—
Stronger than anything before.
The entire underground level shook violently.
Above them—
The university began to collapse.
"…we need to leave," Ace said.
"…not yet," Zein replied.
Ace stepped in front of her again.
"Yes. Now," he said.
Zein held his gaze.
"…if I leave now," she said,"…this doesn't stop."
Ace's jaw tightened.
"…and if you stay, you might not either," he said.
Zein didn't argue.
"…I know," she said.
A long pause.
Then—
"…then I'm staying too," Ace said.
Zein blinked slightly.
"…you don't have to," she said.
Ace's voice turned colder.
"I'm not asking," he replied.
Zein didn't argue this time.
Because now—
They both knew—
This wasn't just a secret anymore.
It was the beginning of destruction.
