Austin had a vague suspicion about the intertwining auras among the four Law Divine Swords.

This level of entities likely involves some rule of the operation of all things in the world, a certain ultimate truth of the operation of heaven and earth.

Or rather, the convergence and operation of Elemental Powers form the cornerstone of the elements of the Prime Material Plane, the foundation of the Prime Material Plane's existence.

Such fundamental laws of the world's operation are utterly impossible for him to grasp now, given that he's only at the Half-Legendary stage.

That Austin could discover such a peculiar phenomenon is mostly due to the inadvertent result triggered by the four Law Divine Swords he had crafted, otherwise, even those in the Legendary Realm couldn't touch upon such a bizarre phenomenon.

If not, those who have comprehended the Law Origin in the Legendary Realm could use Law to wage heaven-shattering and earth-destroying battles.

If that cornerstone of the Elemental Powers of the world is deciphered and applied to battles, it would be akin to the power of a world-ending and rebirth-like force!

"Even if I know its appearance but not its essence, as long as I can follow a certain track or rule, I should be able to manifest the Four Spirits Sword Array through sheer will."

Just like magic, many do not understand its fundamental principles, yet they can still invoke the Elemental Power to unleash Magic through Spiritual Power.

This was exactly what Austin intended.

The Seta Great World had a certain scientific foundation, yet it was more metaphysical, a truth that Austin had realized when developing the Electromagnetic Cannon in his earlier years.

One must know, even in the world Austin had traversed from, Electromagnetic Cannons practical for battle had not yet been completed.

But he, just by relying on some basic electromagnetic principles, constructed a formidable Electromagnetic Cannon through the metaphysical forces of Spiritual Power and Magic Power.

If the scientists of his former life learned of this, they would likely feel deep anguish.

And so is the Four Spirits Sword Array.

Having been unable to analyze the most fundamental principles of the four Law Divine Swords nor deduce the framework of the Four Spirits Sword Array purely through scientific theory, could they use the strength of Spiritual Power and metaphysical magic to complete the remaining steps?

Thus, in wanting to develop the Four Spirits Sword Array, only the operating environment is required, and there's no need to delve too deeply into its operational logic.

Upon thinking, Austin acted.

He immersed his Heart Spirit into the four Law Divine Swords, observing the operational connection from afar.

Since he couldn't analyze the most basic principles, summarizing the external patterns of it should succeed.

For this time, Austin didn't separate the four Law Divine Swords but observed them as a whole.

Before long, he seemingly saw an "orbit" of operation formed by the virtual energy amongst the four Law Divine Swords.

Sure enough, Austin had found the right direction.

In the realm of quantum physics, the macro and micro perspectives are different.

Unexpectedly, some theories from his previous world could be applied here.

Casting away all excess thoughts, Austin refocused his Heart Spirit on the "whole" formed by the four Law Divine Swords before him, observing meticulously and comprehending the certain "principle" within.

Time ticked away slowly.

While observing and comprehending, Austin also experimented externally using the aural operation patterns formed by the four Law Divine Swords as a whole.

Verifying between what he comprehended and experimented with, he indeed made considerable gains.

For example, the transformation of the Rasengan through three Elemental Attribute Powers.

During the time the Pyramid built by the Undead was destroyed, Austin utilized a supremely invincible world-destroying compressed Wind-Water-Thunder Rasengan formed from the transformation of three attributes: wind, water, and thunder, which evaporated the thousands-meter-high Pyramid, erasing it from the earth.

To think, at that time, Austin had just recently entered the Gold stage!

The Rasengan born from the transformation of three Elemental Powers erupted with exponential power, reaching an incredible stage.

However, later on, Austin never used the supremely invincible world-destroying compressed Wind-Water-Thunder Rasengan in battles again, typically resorting to Rasengan of a single attribute.

Why so?

Because, after the two transformations of the Rasengan's nature, the difficulty in controlling it exponentially increased as well.

A slight carelessness would cause a conflict of the two Elemental Powers within the Rasengan leading to its collapse.

If two element's transformation is tricky enough, adding a third Attribute Power only complicates it further.

Precisely why, despite the multi-attribute transforming Rasengan having greater offensive power, in intense battles, it's nearly impossible to spend much energy on gathering a multi-attribute transforming Rasengan.

Thus, after obliterating the Undead Pyramid, Austin never deployed the supremely invincible world-destroying compressed Wind-Water-Thunder Rasengan again.

The reason being, in intense battles, opportunities pass in the blink of an eye, leaving no room to spend time gathering a killing move.

But now, everything has changed.

As Austin took the integration of the four Law Divine Swords as a whole and comprehended the operation of the four Law Powers, he faintly felt a resonance regarding Elemental Power's operational linkage.

Like touching upon a certain bottleneck, advancing further.

While comprehending the four Law Divine Swords, Austin reflected and pondered momentarily, his Spiritual Power invoked within the void.

Boom!!!

Suddenly, visible ripples in the void rippled and twisted, transforming into a vortex.

A large amount of Magic Power surged in, forming a Magic Power Rasengan.

Next, the Law Power fluctuated, causing the rapidly spinning attribute-less Magic Power within the Rasengan to transform in nature.

The Wind and Thunder powers completed their transformation in an instant.

"It worked! Indeed, using the concept of Wind and Thunder Dual Swords Unification as a foundation, combined with my understandings these recent times, the Wind-Thunder dual attributes transforming Rasengan can also be instantly triggered."

Gazing at the dual attribute transforming Rasengan he held, Austin exhaled deeply.

It seemed as though eternally small needle-like electric lights converged within the Rasengan spinning rapidly, and the terrifying power contained within the wind-thunder attribute transforming mixed Rasengan warped the surrounding void, causing visible faint ripples to radiate in the air.

The perfect fusion of the dual Attribute Powers within the Rasengan resulted in a convergence nearly quadrupling the power of an ordinary single-attribute transforming Rasengan!

"What a pleasant surprise."

The frustration from previously hitting bottlenecks while comprehending the four Law Divine Swords instantly vanished for Austin.

Being able to instantly unleash a multi-attribute Rasengan in battle meant significantly amplifying his attack power, enhancing his combat capability enormously.

And all of this could only be considered an unforeseen bounty amidst the comprehension of the four Law Divine Swords.
