Her primordial spirit’s silver light repeatedly dimmed, even showing fine cracks, but under the extreme application of the "Void Law," using space as a buffer, it gradually repaired and adapted.

She continuously "anchored" her own existence: using the "points" of space to counter the "flow" of time; using her steadfast and persistent will (reality) to dissolve the erosion by the illusion of time (void).

Void, reality, time, space... these concepts of the laws were dismantled and reorganized through countless confrontations, verifications, and fusions.

She no longer attempted to forcibly control the rushing river of time but instead became like the most patient listener, analyzing its most fundamental "pulses"—the core rhythms that sustain the flow, reversal, and stillness of time.

She integrated the intricacies of the Void Law into her understanding of time.

Space is the container, time like flowing water.

She could create "gaps" in space to temporarily slow time erosion (slow down), and even simulate time "stasis" (pseudo-stillness) within space folds, or use space jumps to trigger localized, subtle time ripples.

She no longer resisted the will fragments contained in the fragments, but used her powerful primordial spirit to embrace and refine them.

Each fragment of will was like a shadow of previous understandings of the Time Law. Absorbing them was akin to standing on the shoulders of countless giant predecessors, gazing at the vaster secrets of time and space.

Subtle time marks began to emerge around her, like flowing silver meridians resonating with the star trails of starlight behind her.

On this day, the space inside the cave subtly became incredibly viscous, with the distortion from the time acceleration field reaching its peak. Outside, perhaps only a few decades had passed, but inside the cave, a century had truly elapsed.

Si Lingle, seated in meditation within, was covered in dust, like a solidified stone sculpture. But inside, an earth-shaking transformation was occurring.

"Crack—!"

A light sound came not from the cave but from her Dao Foundation, from the boundary of her understanding of time and space.

The three Time Law Fragments surrounding her body shone brilliantly as if burning out, then suddenly collapsed inward, transforming completely into three streams of light of ultimate law, merging into her brow!

Si Lingle’s eyes, closed for a hundred years, suddenly opened wide!

No longer the previous silver-gray galaxy vortex, but a deep and boundless cosmic star sea!

In that star sea, time was no longer an elusive undercurrent but a clearly visible, orbit-like extending silver river!

In her eyes, space also appeared more three-dimensional, filled with numerous understandable and operable "nodes" and "folds."

A majestic momentum suddenly erupted!

The dozens of spatial maze barriers and time barriers surrounding her shattered silently and without trace like fragile glass. The dust settled for a century was shaken free by an invisible force, floating in the air, as if time had paused for her in that moment.

Her long hair moved without wind, each strand as crystalline as jade, glinting with a flowing, cooler-than-moonlight silver brilliance. Her skin was translucent, as if containing starlight. No longer did intense immortal power fluctuations leak out, her aura instead became as deep, restrained, and vast as the universe.

A mysterious law power naturally flowed around her. Under her gaze, a suspended particle of dust instantly weathered away, while another seemed forgotten by time, frozen in place motionless.

This was instinctual control over the power of time—acceleration! Stasis!

"Heavenly Immortal Realm... So this is how it is."

Si Lingle slowly rose, her movements smooth as flowing water, leaving no trace of humanly touch, as if merging with the rhythms of the surrounding space and time.

She could clearly feel the transformed, more powerful immortal power within her body—transformed from pure space power into the more essential and powerful [Space-Time Immortal Power]!

This power was vast as the starry sky, with every strand containing meticulous control of space and an initial mastery of time.

The silver time marks behind her no longer flickered, instead coming to life, like complex star trails flowing with silver radiance engraved beneath her skin, becoming the outward manifestation of her new power system.

With every gesture, it was as if she could pluck the invisible strings of time, stirring ripples in space.

The hundred years of perilous closed-door cultivation exhausted three invaluable Time Law Fragments, but it opened the door to a higher level—[Early-stage Heavenly Immortal]!

More rare was that she successfully performed an initial, uniquely path-integrated fusion between the Void Law (space) and the newly comprehended Time Law.

She stood beside the collapsed bones and silent space fractures (over a hundred years, this place had been covered by new weapon debris and dust, yet the core scene remained the same), her heart clearer and stronger than ever before.

"’Sunken Soldier Abyss’... This is just the beginning." Si Lingle cast her gaze toward the deeper, darker recesses of the ruins, a slight yet confident curve at the corner of her mouth.
