The three of them acted primarily under Ronald's lead.

At this moment, he found a sufficient excuse to deal with the situation, so his decision naturally went unopposed.

Next, they hastily had their first dinner on the island.

The portable provisions, though not gourmet, tasted better after defeating a formidable enemy.

After handling miscellaneous tasks.

While the sun's rays had not yet completely vanished from the sky, they began the excavation of the island's ruins in earnest.

Ronald also did not forget the newly acquired Essence Theory.

During this process, he took the time to recite the texts from the Essence Theory original, thereby gaining control over this original text.

The spells of Essence Theory thus emerged in Ronald's mind.

——[Criticism of Divine]

This spell is a core concept from the first volume of Essence Theory.

Reflected in specific abilities, it allows one to lock onto a Caster and seal the spell they are casting.

Ronald encountered considerable trouble because of this in previous battles.

——[Atomism]

As the name suggests, this spell births from the theory of atoms.

The Caster can use this spell to disassemble any object with actual mass at the atomic level. Furthermore, if the Caster sufficiently understands the nature of the material, they can transform any substance within their understanding.

——[Soul Immortality]

This spell has its unique features.

Although it attacks the opponent's soul, it actually converts part of the enemy's soul into material and then disintegrates it. Compared to typical soul spells, it's more difficult to guard against.

Only someone like Ronald, with defenses as sturdy as a fortress, could withstand such an attack head-on.

——[Soul and Spirit Concept]

Once activated, this spell combines the Caster's concept of death with the death of thoughts, subsequently reflecting on the material plane's life state.

During the spell's duration.

As long as the Caster does not lose the ability to think or abandon thinking, they will not face death, regardless of how dire their condition might be.

——[Athenian Plague]

This spell is a purely simple but powerful attack.

Once successfully cast, a supernatural plague imbued with magical power unfolds immediately, causing immensely lethal erosion to all enemies.

...

The complete set of spells in the Essence Theory is not numerous, but they are exquisite and comprehensive.

Anyone who fully masters it.

Can immediately become a top-notch original holder capable of battling any enemy.

It's just that the casting requirements for these spells…

Upon realizing the specific restrictions of casting Essence Theory spells, Ronald scratched his head awkwardly.

To master the entire original's spells, the difficulty isn't high in theory, yet it's a time-consuming and labor-intensive task.

The requirement for mastering Essence Theory spells is summed up in one word —[Read].

All spells in the original are laid out in order according to the book's content. The holder merely needs to meticulously read the entire book to immediately grasp the first spell.

But for the second and third spells…

This requires repeated deep reading of the original text.

If one doesn't hold the original long-term, it's absolutely impossible for anyone to quickly master all the spells.

This is purely a time-consuming effort!

And for those more common mystics, mastering the spells in the Essence Theory original requires passing various arduous original trials.

—— Actually, mastering this thing isn't easy at all.

Thinking thus in his heart, Ronald casually transformed the original into a mark and stored it in his hand.

Even though he hadn't gained access to all the spells.

Yet, due to the action of storing it away, it seemed he had prematurely understood the effects of the Complete Technique in the Essence Theory.

——[Immortal Matter]

This Complete Technique is simple yet powerful.

The limitation lies solely in the Essence Theory's own lengthy incantations, which need to be recited in order, leading to timing issues.

However, considering the spell's effect, this flaw is not a problem at all.

Once the[Immortal Matter]Complete Technique is successfully cast, it can immediately add an absolute material quality to the target, almost indestructible by anything in the world.

Upon understanding the details of the[Immortal Matter].

Ronald's confusion about this spell was also finally resolved.

Due to the main ideological trends in the original, the[Immortal Matter]spell cannot protect the Caster themselves but can only be applied to the surrounding objects or the original holder's companions.

Thinking carefully, it indeed makes sense.

In Ronald's experience, neither the great Mage Shui from[Lachmont]nor the Caster from[Nine Commandments Society]whom he just killed.

After successfully activating the Complete Technique.

Applied this perfect defensive capability to themselves; rather, they chose to bestow it upon their surroundings or companions.

Ronald, however, had no issues with such a limitation.

After all, he himself possesses[Humanity's End], an even more superior defensive spell than[Immortal Matter], albeit with a relatively short duration.

In the future, as long as he successfully gains access to all the spells in this original.

By then, applying the effects of[Immortal Matter]to his companions, while Ronald himself enjoys the protection of[Humanity's End]. This way, the complete defense of his faction can almost be achieved.

As for the requirement of repeatedly reading the original to master the spells…

Ronald has always been fond of reading, so this condition, rather than being a test, coincidentally aligns with his interests!

One piece of good news after another, truly couldn't be better!

Thinking so, Ronald once again threw himself into the excavation process of the surrounding ruins.

However, until sunset, the three of them had not found any valuable discoveries here.

In the previous battle, Ronald's enemy summoned a flood, burying the deepest underground space in the water, smashing most things like a real tsunami.

Coupled with subsequent burial and compression, finding anything valuable here is as difficult as scaling the heavens.

The situation gradually worsened, but Ronald did not feel discouraged.

In excellent condition, his thoughts became even more active.

Observing the current scene, Ronald recalled the details from the battle.

He thought of the nun he rescued, who was later buried on the island.

When he found her, the room where the nun was could store quite a number of books; it's only because the situation was urgent at that time that Ronald had no time to study those books.

Thinking it over now…

The cave in the central layer did not suffer from the tsunami as the bottom layer did.

Just being filled with surrounding soil.

The books there definitely still hold quite important information!
