Regression of the Vector Magician

Reyon stood before the grand doors of the Phoenix Vault, his heartbeat steady but his mind racing. This was the moment he had long awaited—not just in this life, but in the previous one as well. He had always wondered why the vault was hidden so carefully, why even as a member of the Phoenix family, he had never been allowed to step foot inside. Now, standing at the entrance, he realized the reason.

The doors creaked open, revealing a sight so extravagant that it made even the royal palace seem lackluster in comparison. Rows of artifacts, glowing with immense magical power, filled the chamber. Every item here could be considered a family heirloom to other noble households, but within the Phoenix Vault, they were merely part of a collection.

However, Reyon wasn't here for treasure—he was here for knowledge.

His feet carried him toward the center of the vault, where the most valuable artifact was displayed. Mounted on the wall, inside a transparent frame infused with layers of Vector Magic, was a single ancient tome. It radiated an invisible force, sending shivers through the air around it. Reyon didn't need confirmation—he knew immediately.

This was Leywin's book.

This book had once been the greatest lost artifact of his past life. He had only ever seen fragments of its knowledge, its pages burnt and incomplete when he first encountered it. But now, here it was—whole and untouched, shielded by the very magic only a Vector Magician could bypass.

Reyon extended his hand, letting his mana flow through the symbols of £ (Epsilon) and § (Delta), aligning with the protective barrier. As expected, the moment his vectors synchronized with it, the frame dissolved into thin air. No one but a true Vector Magician could access this book.

He grasped it firmly, feeling the weight of history in his hands. As he flipped open the pages, his eyes widened. The book contained more than he had ever imagined.

The Lost Symbols: A New Path

There were two previously unknown symbols that had never made it into the fragments he had discovered in his past life:

σ (Sigma) – A symbol that reduced the resistance of magic transfer. Normally, when casting a spell, half the mana gets wasted due to inefficiencies in circulation. But with σ, the efficiency could be increased from 50% to 60%. At first, it seemed like a minor increase, but Reyon knew better—even a 10% boost in mana efficiency was an immense advantage in battle.

φ (Upsilon) – This symbol was designed to protect the brain. Controlling Vector Magic required twice the mental strain compared to casting traditional spells. This was the biggest limitation of Vector Magicians—their minds couldn't handle the extreme burden of calculations and control. Leywin had found a solution.

Reyon's fingers trembled slightly as he turned the pages. He finally understood why no one else had been able to master Vectors the way Leywin did. It wasn't just about talent—it was about knowledge.

The Power of Stacking: The True Potential of £ (Epsilon)

Then, he came across the greatest revelation of all—a detail about £ (Epsilon) that had been completely lost in his previous life.

Until now, he had believed that £ was only capable of converting surrounding mana into vector-based spells. But according to the book, that was only its basic function. The true power of £ lay in its ability to STACK other symbols.

By stacking £ + σ, he could keep reducing the resistance of magic transfer, potentially reaching 100% spell efficiency—or even surpassing it.

However, there was a grave warning. Stacking too much took an extreme toll on the brain. It could cause brain damage, unconsciousness, or even death.

Leywin had found a way to bypass this risk.

He had designed a ring—the Ring of Ferica—which worked in perfect synchronization with φ (Upsilon).

φ transferred the mental strain of vector calculations onto the ring instead of the caster's brain.

Without the Ring of Ferica, using £ to stack σ would eventually kill the user.

Reyon clenched his fist. No wonder he had reached a limit in his past life. The missing piece wasn't just the knowledge of stacking—it was the artifact that made it possible.

But there was a problem.

Where Was the Ring of Ferica?

There were no mentions of its location in the book.

Reyon's mind raced. If the ring had been recorded in this book, it meant that it had to exist. Leywin wouldn't create a technique he couldn't use himself.

But if it was missing, that meant one of two things:

It had been lost somewhere, hidden outside the Phoenix House.

Someone had already taken it, and its whereabouts were unknown.

Reyon's eyes darkened. If he truly wanted to surpass his limits, he needed to find that ring.

His thoughts were interrupted by a voice.

"Young master, the Clan Head is calling for you. If you have picked what you want, please report."

A maid stood at the entrance of the vault, waiting for his response.

Reyon exhaled slowly, closing the book. He had no time to waste.

"Understood," he said, his voice calm. He took the book under his arm and left the vault, stepping into the next phase of his journey.

He had gained powerful knowledge, but now, a greater challenge awaited him.

He needed to find the Ring of Ferica—and uncover the true depths of Vector Magic.
