Starting with Proficiency Panel-Chapter 583 - 580: The heart is infinitely vast, and the physique is infinitely vast.

As he rushed into the thunder tribulation, Lu Ren felt the surrounding destructive power burst onto him with incredible intensity, like stepping into a world made of thunder, with every movement bombarded by massive thunder forces.

Bang!!

In that instant, a colossal roar echoed within Lu Ren's body, as if a heavenly furnace had been fully ignited, with layers of witch power transforming into radiant halos, releasing an exceedingly terrifying power that instantaneously repelled the surrounding thunder.

His entire physical form began to glow at that moment, and Lu Ren distinctly felt that, although the thunder continuously crashed against his body, inflicting substantial damage, his flesh recovered and regrew stronger than before the bombardment.

Lu Ren gained a profound understanding in his heart; while the thunder carried an ultimate destructive power, when destruction reached its peak, it was like yin giving birth to yang, evolving a pure vitality to compensate for the damage inflicted on his body.

For ordinary cultivators, facing such a degree of thunder tribulation and surviving until the thunder transforms from destruction into vitality would be impossible.

What is an Ancestral Witch? Is it merely a ranking of bloodline?

Suddenly, an inexplicable thought rose in Lu Ren's mind, stirring his previously calm emotions into waves of turmoil.

Is a Witch truly just pure cultivation of physical power?

In truth, this is not exclusively the case; even the purest of Witches, upon merging spiritual power with physical form to achieve an integrated state, would blend spiritual power into their flesh.

Hence, the heart becomes infinitely vast, engendering an infinitely vast power from one's physique.

"Ultimately, it is the heart that leads, with the physical form manifesting its intent, isn't it."

Lu Ren realized, finally understanding why some extraordinarily talented Witches reach the Ancestral Witch Realm, unlike those unable to grasp its essence with minds filled only with muscles.

Yet, a question remains as to why, after achieving the Ancestral Witch Realm, the Ancestral Witches do not correct the cultivation path of other Witches but allow them to continue without any opportunity for breakthrough throughout their lives?

Is it because their aptitude is truly insufficient, or is there another reason?

Boom!

The contemplation did not last long; as Lu Ren threw a punch, another explosive boom resonated, shattering the thunder aimed at him like a meteor strike.

Then Lu Ren withdrew his hand, letting the thunder refine his physique.

Much like fire engulfing his body, his blood turned to magma, raising the temperature within a thousand-mile radius, even causing the dense moisture in the tribulation clouds to evaporate, spreading a layer of ethereal mist over the terrain.

Thunder continued to inflict damage, leaving marks on Lu Ren's body, but the moment the thunder dissipated, those small wounds instantly healed, as if never harmed.

A day later, witnessing no more system notifications popping up in his mind about his physique skill level growing, nor any advancement in the cultivation of the World Honored One's Heart Sutra, with the surrounding thunder no longer harming him, he looked upward.

There, deep within the thunder.

"It has been a whole day and night; why hasn't this thunder tribulation dispersed? Instead, it's becoming more dense? What is he doing inside to make the tribulation clouds persist and grow stronger?"

Observing from afar, the cultivators were astounded; typically, a heavenly tribulation lasting half a day is considered fierce, yet after a full day and night, the tribulation clouds not only haven't dispersed but seem to be awakening something, accumulating potential energy.

Someone nearby responded, "Hey, rushing into a heavenly tribulation like that; heaven's majesty cannot be defied. If it doesn't retaliate severely, won't it be shattered by this thunder before stopping?"

"To be a Celestial Pride, to stand apart, one must be prepared to face envy from the heavens, especially when actively striking the tribulation clouds."

Some watched with excitement, others made disparaging remarks, cold glances, or somber expressions; a multitude of complex emotions displayed across hundreds of faces.

Indeed, as the tribulation cloud's force grew and persisted, from initially viewed by only a dozen to several hundred spectators by day's end.

It's ingrained in human nature to watch lively events, to go forward and take a look whenever something happens.

And on a distant hillside, appeared a Fierce Person at some unknown time, quietly observing the tribulation clouds, her gaze seemingly piercing through layers of barriers, fixed on Lu Ren within the Sea of Thunder.

She wore a white robe, with a black-golden mask on her face, her expression indifferent, revealing nothing of her thoughts.

Feeling this somehow, Lu Ren's eyes gleamed with brilliance as he penetrated the tribulation clouds, raising an eyebrow when he saw the Fierce Person observing him.

With Beidou so vast, and merely the Eastern Wilderness surpassing Earth countless times, how could they still meet?

Though grumbling inside, Lu Ren harbored no desire to retreat, possibly facing the sole opportunity to confront tribulation clouds in the Heaven-Covering World; missing it would bring regret.

What lies deep within the tribulation clouds?

In Heaven-Covering, Ye Fan braved the thunder tribulation, venturing into its depths, discovering a Thunder Pool filled with exceptional thunder liquid. 𝕗𝕣𝐞𝐞𝘄𝐞𝚋𝚗𝗼𝘃𝗲𝗹.𝚌𝕠𝚖

Who knows if such wondrous things still exist in this era.

Lu Ren strode upward, provoking the tribulation to unprecedented fury, with once indigo thunder turning deep purple, continually striking him.

Yet despite this, Lu Ren's steps remained unyielding, letting thunder rain down - his body had developed moderate resistance over such prolonged exposure.

Only from further above, where scarlet lightning flickered, did Lu Ren sense danger.

As Lu Ren prepared to step further into the thunder boundary, he suddenly paused, gazing down at a figure abruptly standing before him.

It was a being of thunder, faintly forming a humanoid shape, imbued with power demanding Lu Ren's utmost vigilance.

"Is it one of those historical Celestial Prides of unparalleled brilliance, etched into the cosmos during breakthrough, now revealed?"

Lu Ren pondered, recalling countless extraordinary, even monstrous, Celestial Prides in Heaven-Covering, who during grand breakthroughs, imprinted their presence into the cosmos—triggering a manifestation.

Who then stands before him, from history's lineage?

This thought swiftly passed as Lu Ren fiercely struck forth.
