In the library of the Abyssal Observation Station, inside a small reading room protected by special runes.

This space, personally arranged by Uther, possesses the most stringent privacy protection within the observation station.

"Silence Stones" are embedded in the walls, completely blocking any form of spying and eavesdropping.

The room is small, accommodating only a round table and four chairs.

Yet, it is precisely this confined space that creates an intimate and focused learning atmosphere.

The tabletop is carved from a single piece of Abyss Obsidian, smooth as a mirror, clearly reflecting every expression change of the participants.

Ron sits facing the door, allowing him to perceive any possible disturbances at the first moment.

To his left, Uphemia is focused on reading a heavy theoretical tome.

Her white long hair cascades down her shoulders like a waterfall, emitting a silky sheen under the illumination of the Magic Crystal Lamp.

Today, she is noticeably more relaxed than when they first met.

The deliberately maintained perfect facade has disappeared, replaced by a scholar’s unique expression of concentration.

On the right, Chloe still shields her eyes with black silk, silently sitting in on the session.

"The core of Curse Reversal lies in redefining the chain of causality."

Ron’s voice is exceptionally clear in the quiet room:

"Traditional curses follow linear logic: the caster uses runes and Magic Power to produce specific effects on the target. Curse Reversal, however, folds this process spatially."

He uses Spiritual Power to sketch a complex three-dimensional diagram on the tabletop.

The figure resembles a twisted ribbon.

The surface and the inner side connect at a peculiar node, forming an infinite loop with no distinction between inside and outside.

"Look here..." Ron’s finger points to the critical node in the diagram:

"When the magic’s Energy Flow passes through this reversal point, the roles of the caster and the target are swapped.

The person supposed to endure the effect becomes the source of the effect, while the original caster becomes the recipient."

Uphemia frowns, her face filled with confusion:

"But this swapping... what are its triggering conditions? If Curse Reversal is so powerful, why doesn’t every wizard learn it?"

As expected of Number Eighteen, outstanding among so many test subjects, indeed very clever.

Ron nods in approval: "A very good question. Curse Reversal is indeed powerful, but its limitations are equally stringent."

He adjusts the energy diagram on the table, adding more details:

"First, the reversal process requires an extremely deep understanding of the original curse.

You must perceive every rune node, every Energy Circuit, and even completely grasp the Spiritual Power signature of the caster."

"Secondly, the timing of the reversal must be extremely precise.

Too early, and the curse hasn’t fully formed; too late, and the effect is irreversible.

This time window is often just a few seconds, or even shorter."

He pauses briefly, his expression becoming more serious:

"Lastly, and most importantly.

Each use of Curse Reversal causes permanent damage to the soul of the user.

This damage is cumulative, and when it reaches a certain critical point..."

"What happens?" Chloe, intrigued by the direction, inquires softly.

Though her eyes are shielded, her "gaze" is exceptionally focused.

"The soul shatters, consciousness dissipates." Ron unreservedly explains this dreadful consequence:

"Historically, most wizards who attempted to study this art did not meet good ends.

They either died from soul collapse or were killed by a rebound during a failed reversal."

This candid statement of risk leads both women into contemplation.

Especially Chloe, who recalls those astrologers who perished from the rebound due to over-probing the rivers of fate.

"However..." Ron changes his tone:

"In your special case, Uphemia, these risks are controllable. 𝙛𝓻𝒆𝒆𝒘𝙚𝓫𝙣𝙤𝒗𝙚𝓵.𝙘𝙤𝙢

Because what you need to reverse is not an external curse but a Control Mark deeply rooted in your bloodline."

He adjusts the energy diagram again, presenting an even more complex model:

"The control means Aiden left in you is essentially a continuous bloodline curse.

It is deeply integrated with your Life Energy and Magic Power circulation, forming a relatively stable Energy Circuit."

"And in this situation, Curse Reversal is more like... changing the direction of a river, rather than reversing the fall of a waterfall. The difficulty will be greatly reduced, and the risks correspondingly decreased."

Hope reignites in Uphemia’s eyes: "So I have a chance to succeed?"

"Not only a chance but a fairly high success rate." Ron provides a clear answer:

"As long as you can fully master the theoretical foundation and remain sufficiently patient and cautious during practice."

In the next two hours, he meticulously elaborates on the fundamental theory of Curse Reversal.

From the reorganization of runes to the precise control of Energy Flow, from the stratified use of Spiritual Power to the key points of consciousness anchoring technique.

As a skilled lecturer who has taught many courses, Ron has developed his own teaching methods.

He carefully organizes each knowledge point listed by Uphemia.

Ensuring the completeness of theory while considering the learner’s capacity to absorb it.

Uphemia, on her part, demonstrates an astonishing learning prowess.

As a perfectly crafted artificial being, her memory and comprehension far surpass those of ordinary geniuses.
