Zombie Apocalypse: I Have Safe Zone Superpower-Chapter 581: Subtract

A faint realization struck her.

’So that’s why...’

That was why the temperature inside her base had always remained stable whenever her power was active.

It wasn’t coincidence. It was her aura.

A protective field that made everything within its range resistant to harsh conditions.

Her eyes slowly widened, a soft glimmer forming within them.

"I never noticed..." she whispered. ’In my previous life... I never understood this at all.’

A faint smile tugged at her lips. ’This power... is incredible.’

With renewed focus, she turned back to the manual. It instructed her to visualize her power...

Not as something abstract, but as something tangible. Like a drawing.

At first, Ivy struggled. Her mind felt blank no matter how hard she tried to picture it.

Frustration crept in. "Why can’t I see it...?"

But then, as she reread the lines carefully, she finally understood.

She didn’t need to imagine it out of nowhere... She needed to trace it.

Using her heightened senses, she could already feel how far her power extended.

All she had to do... was outline it. Slowly, she began mapping it in her mind.

The edges. The reach. The density. And then... It appeared. A complete structure.

Her power... Looked like a whole cake.

A vast, layered cake encompassing everything within its range.

The moment she saw it clearly, her breathing steadied. ’Now... I can cut it.’

She focused on one side of that "cake" and attempted to slice off a portion.

The first attempt... Failed.

The second... Barely made a dent.

It required immense concentration, far more than she had ever used before.

Even after an entire week, all she managed to achieve was a faint, almost invisible "cut."

From an outside perspective... It would have looked like she was doing absolutely nothing.

But Ivy knew better. Her jaw tightened slightly. "I’m close..."

She didn’t skip a single hour.

Time blurred as she continued again and again, relentlessly trying to carve out that excess portion of her power.

The strain built up. Her head throbbed. Her body felt heavy. But she didn’t stop.

And then... After three weeks... It happened.

A piece... separated. A real, tangible portion of her power was finally cut off.

A faint wave of exhaustion washed over her, but beneath it... There was satisfaction.

....................

During this period, Silas had already departed to deal with the cables, leaving Ivy alone to focus entirely on mastering her ability.

Meanwhile, inside the Temporal Storage, her crops had flourished.

Cabbages, carrots, tomatoes, potatoes, onions, garlic, even spices like red chilies and oregano, etc.

Everything had grown to perfection, ready for harvest.

When Ivy stepped in and saw the sheer volume, she froze for a moment. "So much...?"

The sight was overwhelming. The fresh scent of vegetables filled the air, earthy and rich, almost intoxicating in its abundance.

’Even if I sell these... I’ll still have more than enough left.’

But she didn’t act impulsively. Instead, she carefully calculated what she had.

’I should secure enough for my faily first...’

That was her principle. Family came first. 𝓯𝓻𝒆𝙚𝒘𝓮𝙗𝓷𝒐𝓿𝙚𝒍.𝙘𝓸𝙢

And so, she stored a large portion for her own use before deciding what to sell later.

At the same time, she remembered something important.

Silas’s condition for upgrading his power.

Without hesitation, she prepared a massive quantity of vegetables specifically for him and stored them into his temporal storage.

When Silas returned and touched it, a faint emotion flickered across his face.

"After completing this mission I can proudly stand by your side," he said quietly.

His voice carried determination.

Ivy tilted her head slightly, curiosity appearing in her eyes. "You mentioned a mission...?"

Silas smiled faintly, as if he had already expected the question.

"My system assigned it to me," he replied. "I need to absorb the power from the cave."

For a brief moment, his expression darkened slightly, as if recalling something.

That shadow... He then looked at Ivy, his gaze turning serious. "I won’t have much time to communicate."

A pause. "Take care of yourself."

His voice softened, but the weight behind it grew heavier. "And don’t do anything reckless."

Another pause. "Even if you want revenge... wait for me."

Hearing those words, Ivy felt something tighten in her chest.

She nodded slowly, her eyes lingering on him with quiet reluctance.

"I will."

.....................

After he left, Ivy returned her focus to her power. Days passed once more.

Within the next two weeks... She achieved something remarkable.

Half of her power... Was cut away.

This time, the reduction was massive. The protective range shrank significantly, concentrating more densely where it mattered most.

However... As she tried to go further, she felt it.

A limit.

Her control... had reached its current peak.

She exhaled slowly, her body slightly trembling from exhaustion. "This is... as far as I can go for now."

She couldn’t allocate that extra chunk of the protective circle she had sliced away from her base. No matter how hard she tried, she couldn’t maintain a stable distance between herself and that detached portion of power.

Every time she attempted it, the connection would waver, like a fragile thread stretched too far.

’I can cut it... but I can’t place it.’

A faint frustration settled in her chest. "And I can’t just let it float aimlessly..." she muttered under her breath, her brows knitting together.

So, she had no choice. She practiced. Every single day.

.........................................

Two months passed in a blur.

Time slipped by quietly, marked only by her constant effort. During these two months, Ivy devoted herself entirely to mastering her power.

And finally... There was a breakthrough. A real one. She could now allocate the sliced portion of her protective circle to specific individuals.

Not only that... The distance between her and those assigned fragments could exceed a thousand kilometers.

Even for Ivy... That was astonishing.

Her lips parted slightly as she observed the result. "I actually did it..."

.........................................

At the same time, the outside world began to behave strangely.

The cold... It no longer remained constant.

Instead, it fluctuated unpredictably, as if the world itself couldn’t decide whether to freeze over completely or ease into warmth.
