Ron listed many flaws of this magic: "But the basic construction is very stable, perhaps it can be used as a blueprint to develop new variants."

He recalled the records he had seen in "The Apprentice's Ladder":

Many powerful spells are actually evolved from basic magic, the key is to discover and utilize the potential of the basic structure.

"If we change the slime to acid, increase the corrosiveness, and simultaneously enhance the ejection speed and range..."

Ron stood up and walked to a wooden humanoid target in the center of the laboratory.

This target was specifically used by him to test attack magic, its surface covered with special magic sensory material, able to record detailed data of the magic impact.

He took a deep breath, concentrated his spiritual power, and constructed the magic model of "Slime Splash."

But this time, he did not follow the standard structure completely and tried to adjust a few key nodes.

"Change the liquid density, reduce viscosity, enhance fluidity..." Ron adjusted the magic parameters in his mind.

The proficient level of "Magic Construction" skills and multiple professions related to spiritual power were functioning, aiding him in quickly completing this basic improvement.

As the spiritual power poured in, a faint green glow emerged from his palm, a blob of liquid slowly forming in his hand.

Unlike the original version, this blob of liquid appeared clearer, with greater fluidity.

"Go!"

Ron softly commanded, swinging his palm towards the wooden dummy.

The blob of liquid shot out like an arrow, its speed at least double that of the original "Slime Splash."

"Pa!"

The liquid hit the wooden dummy and quickly spread out.

A moment later, white smoke began to rise from the wooden surface, the area covered by the liquid being slowly corroded.

"The basic direction is correct, but the effect is still not ideal."

Ron frowned and evaluated: "The attack speed increased, but the corrosiveness was far from expected."

He walked back to the workbench and opened a heavy ancient tome "Theory of Spellcasting Medium."

This book detailed various media substances used to amplify magic throughout the history of wizards.

"Spellcasting Medium..." Ron murmured, excitement flashing in his eyes.

In the construction of magic models, integrating external substances can significantly amplify the magic effect.

This is an extremely ancient technique, from the most junior apprentice to the top Witch King, they have been constantly exploring the possibilities of this field.

The most basic spellcasting medium is the energy crystal, usually crafted by alchemists.

These crystals store pure magic power internally, which can provide additional energy during casting, enhancing the magic's potency.

"Although energy crystals are the most convenient to use, the effect is quite limited." Ron flipped through the pages, calculating in his mind:

"Moreover, the utilization efficiency is extremely low. After injecting a spell with a standard quality energy crystal, it can only enhance the power by about 20%, consuming the entire crystal's energy, compared to various magic wands, it's a complete resource waste."

More advanced spellcasting mediums are substances with special effects.

For example, Fire Dragon Heart Blood can significantly increase the temperature and duration of fire magic;

Sky Serpent Scales can provide more precise guidance for thunder magic;

And Moon Shadow Flower pollen can enhance the bewildering effect of illusion techniques.

Ron's gaze fixed on a particularly noteworthy record:

"...As for liquid magic, biological secretions are often the most ideal spellcasting medium.

These fluids processed through special glands within the biological body inherently carry unique magic marks, which can produce effects far surpassing pure construction when combined with the caster's spiritual power..."

"Biological secretions..." Ron's eyes brightened, a clear idea appearing in his mind.

Ever since Dale refined herself at the bloodline altar to become a Golden Ring pure-blooded Sea Siren, her physical capabilities have significantly evolved.

One significant feature is that the special corrosive liquid she could initially secrete has now also been enhanced.

"Perhaps Dale's secretion can be tried as a spellcasting medium..."

Ron pondered, then stood up and walked out towards the workshop.

He found Dale in the small training ground in the backyard, practicing Water Element Control.

The Little Sea Siren was focused on controlling a water ball, transforming it into various shapes in the air.

From simple geometric forms to complex animal contours, showcasing her increasingly refined control.

"Dale." Ron called out.

The Little Sea Siren turned upon hearing the sound, her eyes flashing with surprise.

The water ball instantly transformed into a delicate water flower, blooming in the air before disappearing without a trace.

"Master! Is there anything I can help you with?"

She eagerly ran over, her silver hair sparkling with metallic luster under the sunlight.
