Legendary Magic Quill (2)

Park Ha-jun smirked, twisting the corner of his mouth. Adjusting the graph to raise the upper limit.

As both a mathematician and a scroll maker, his curiosity surged.

What were the constraints? How far could the limits go...?

......

He bought 50 sheets of low-grade parchment from the Exclusive Shop. He listed all possible cases in his notebook.

And drew them himself to grasp the constraints and limits.

His goal was to fully understand Circuit Reinforcement.

The result?

......

The limit was 3. Anything beyond that...

Crackle-

The circuit on the scroll burned black.

It was probably because of this 'capacity limit.' Incidentally, designing for destructive power of 3 required making mana consumption efficiency utter crap.

But there was no need to feel regretful. Didn't he have Circuit Reinforcement in his skill list?

Maybe he could raise the limit even further with a 'Skill Enhancement Ticket.'

And above all, this was just the 'designed' base destructive power.

If he drew a perfect circuit on high-grade parchment...

......

A scroll surpassing the destructive power of a 5th-circle mage was born.

Furthermore, on legendary-grade parchment, 'Destructive Power: 6' was possible.

Of course, he wasn't sure if there'd be demand for such scrolls. Their commercial value might be a bit low.

However.

'...This should deal some damage even to divine monsters like Garuda.'

It wouldn't be useless. Sometimes, sheer brute force was necessary.

'Anyway, the limits are like this...'

Park Ha-jun summarized the limits and noted the constraints in his notebook.

'The constraints are a one-to-one function and continuous...'

...He just needed to understand that he couldn't draw bizarre graphs into the circuit.

He even got a paper idea from this part.

But he jotted it only in his notebook and opened the Exchange.

He'd unintentionally drawn 50 non-attribute magic bullet scrolls, hadn't he?

Ten of them had burned circuits and were headed for disposal, but leaving the remaining 40 in the workshop would just be clutter.

He listed all 40 on the exchange.

Their performance was generally like this.

Drawn on low-grade parchment, the destructive power was below 3.

Still, they were scrolls with overwhelmingly impressive stats.

'Hope it helps...'

He'd heard there were hunters with gate raids scheduled right after suppressing the wave.

He sold them at a price that wouldn't burden those hunters.

Next, he sent the one scroll drawn on high-grade parchment—[Base Destructive Power: 3.9] non-attribute magic bullet—to Lee Dong-gyu.

With Garuda looming, it was like informing them of his growth so the association could factor it into their Garuda subjugation plans.

After handling all the experimental scrolls, he roughly checked the Ancient Grade Circuits.

Several themes existed.

[Special Attributes] [Time] [Space].

Only [Special Attributes] glowed blue. The other themes seemed to require additional gold.

"..."

Park Ha-jun skimmed through, nodding intriguingly.

Then he tidied the workbench ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠and headed to the bedroom.

This was truly the limit now. Tomorrow, after sleeping, he'd research the 3rd-circle—Explosion—circuit.

He fell asleep as soon as he closed his eyes.

Swish.

A sand hourglass two stories tall.

The purple sand inside flowed backward. From bottom to top. Extremely slowly.

"..."

The Mine Bishop swallowed a groan.

This hourglass was like the Mines' activity level.

The more sand piled on top, the more aggressively the Mines could act.

The condition for that sand to accumulate was humanity falling into chaos.

Yet.

"...It's slow."

Cracks had appeared in capitals worldwide, and swarms of monsters had emerged, hadn't they?

Yet the hourglass sand only flowed backward quickly on the first day.

Less than a day later, the reversal speed had drastically slowed.

That had delayed Garuda's summoning. The sand had only now reached the necessary amount.

The reason was simple.

Crack-

A phenomenon from a single sheet of parchment.

The vast sky swept by Infinite Proliferation Frost Wind, clearing A-rank flying monsters.

asd123 had sown seeds of hope.

'...I expected it.'

From the moment he'd cleanly resolved the Basky incident, he hadn't expected the waves to achieve his goal.

He was just painting a bigger picture. He'd accumulate more sand in the hourglass and target him.

But that didn't mean he'd grant humanity a peaceful victory.

asd123 overcame crises with unique phenomena each time...

'...But they're meaningless before overwhelming power.'

The Bishop reached toward the hourglass. Soon, the sand piled on top cascaded down.

"...Commencing summoning."

The summoned Garuda would wreak havoc on humanity's dimension.

If even one or two S-rank hunters died, humanity would plunge into great chaos.

With that full sand, he'd neutralize asd123...

Swish.

The moment all the sand fell.

From the center of the rift over Beijing, vast energy plunged to the ground.

Craaaash-!!!!

Within the endlessly plunging energy, Garuda slowly took form from its toes upward.

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

Crossing dimensions required time for such immense power.

The next day.

Park Ha-jun was organizing his newly assigned lab.

It had been a storage room from another department.

The board of directors had hastily provided it upon seeing his research achievements.

Once he finished organizing and brought in equipment, he could start operations?

Two labs. One for his projects, the other for magic fusion research.

Switching roles every quarter would reduce fatigue.

'...After successfully wrapping up this wave, let's hire three more researchers.'

While tidying, he sensed a presence and looked toward the door.

Kim Ah-hyun stood there, clutching a scroll preciously to her chest.

"..."

Seeing her hesitate, Park Ha-jun tilted his head.

"Um... I bought this. Professor, would you analyze it with me?"

With those words, she presented the scroll.

It was the scroll he'd posted yesterday afternoon.

"Haha... You bought this one."

Kim Ah-hyun nodded and showed him her smartphone.

It had been a while since he'd seen the hunter community.

......

The comments were full of provocative stuff. That's why he'd deliberately avoided looking...

Kim Ah-hyun pointed to one comment with her finger.

Then she looked up at Park Ha-jun.

"These people are underestimating you, Professor. Let's research it together and show them it's possible."

Kim Ah-hyun surely knew he was asd123.

He hadn't denied it in their last conversation.

Even so, she was tactfully requesting guidance while avoiding questions that might put him in a tough spot.

Her passion and consideration pleased him greatly.

"Of course. If you'll help with the research, I'd be delighted. But..."

There was something to handle first. When Kim Ah-hyun showed her phone, an email from Lee Dong-gyu had arrived.

Kim Ah-hyun nodded, hiding her sulky expression.

"Tomorrow, let's analyze the circuits together."

Specifying the date finally brightened her face.

"Yes...!"

After sending her off, he read the email.

After reading the email, Park Ha-jun sat in a chair in the corner of the new lab.

It was perfect for focusing alone.

And the goal was simple. The strongest attack-type scroll.

A scroll capable of shredding Garuda's wings.

At minimum, one that could inflict major damage on the wings.

'Not much time to spare.'

No time to unlock 4th-circle or analyze new circuits.

He'd send Explosion, which he'd glanced at a bit. It was fire-attribute and destruction-focused.

He bought legendary-grade parchment from the Exclusive Shop.

No special effects, yet 100 million gold.

But 100% mana limit tolerance was overwhelmingly powerful in itself.

Having sufficiently practiced Explosion on mid-grade parchment, Park Ha-jun made two Explosion scrolls on legendary-grade parchment. It took about three hours.

His geometric interpretation ability had slightly improved since the last skill enhancement ticket, hadn't it?

Even so, perfecting Explosion took considerable time because it wasn't an ordinary one.

'...Anyway, better send it quick. Three hours flew by.'

Fortunately, he'd brought an item transfer tool for emergencies.

He sent the scrolls through it, then returned to the main lab.

Around that time in Beijing.

Lee Jong-hwa, who had successfully aided the US and come straight to Beijing without regrouping.

The emergency meeting options had narrowed to two.

Fight, or buy more time with Seo Ji-ah's barrier.

The latter would allow support from more countries.

They could ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠clear more of the stray mobs rampaging in Chinese airspace.

But.

"As you see, without S-rank firepower, more support is meaningless. And those mobs..."

Kwaaa-

Vast energy plunging from the rift over Beijing.

And in response, energy from Fragment of the Story was slowly manifesting Basky.

But the ordinary Naga clan—not divine monsters—were already summoned and fighting the flying monsters.

"They're handling it well enough. No need to delay the fight."

Basky, who had rampaged on Earth not long ago.

It was ironic to receive his help.

[The Naga clan will lend strength to the decisive battle against Garuda.]

Since the damn system vouched for them as allies, no needless worries.

'...A bit concerned about Basky's venom.'

He was reasonable, so they'd try talking.

Anyway, there'd be casualties, but by the felt aura, Garuda subjugation wouldn't fail.

Rumble.

Thus, Lee Jong-hwa used Lightning Strike where feasible.

At the same time, harboring some expectation.

Lee Dong-gyu said he'd sent ample gold to asd123—had he bought the Legendary Magic Quill?

If so, what changes would come...?

While clearing flying monsters rampaging over Beijing.

"President!"

Assemblyman Jeong Hyeon-seok arrived via mass teleport magic, holding two scrolls.

"...You're here."

Jeong Hyeon-seok nodded with a grim expression.

Lee Jong-hwa lightly extended his hand, and Jeong confirmed again before slowly handing them over.

"Not ordinary scrolls this time either, I see."

He checked the received scrolls.

"..."

The insane one had arrived.
