Reborn as an Extra Chapter 745: You can change this world, Rio! Part-3.

Upon hearing Rio’s account, Raika shifted the perspective back to the devastated planet once inhabited by the Nebo Civilization, his voice resonating with solemnity.

"The ultimate downfall of the Nebo Civilization, despite its former might and prosperity, was the catastrophic 'Mana Descent' Incident!"

As if initiating a playback, Raika's personal realm began to vividly depict the unfolding events.

One moment, the inhabitants were immersed in their peaceful daily lives; the next, an inexplicable distortion rippled through the very fabric of existence, fundamentally altering the universal laws.

Widespread chaos erupted, and tragically, the Nebo civilization's homeworld proved incapable of adapting to the abrupt transformation of the universe's core 'laws.'

Their planet, having been frequently graced by the old universal rules, was intrinsically bound to them. This sudden shift in foundational principles unleashed a devastating cataclysm upon their world.

The planet itself fractured and disintegrated, resulting in the instantaneous demise of hundreds of millions of innocent souls.

Such a calamity was beyond prediction, even for the Nebo Civilization, renowned for its foresight. The very 'laws' they employed for prophecy had been irrevocably changed.

"Humanity was acknowledged by mana, gaining the potential to become Awakeners, owing to the birth of 'Astra,' who compelled the 'law of mana' to recognize her innate talent..."

"Consequently, this made humans compatible with mana, bestowing upon them the power of awakening..."

"However, not all races were fortunate enough to adapt..."

"Those races that failed to earn mana's acknowledgment either succumbed to mana poisoning or faced extinction, unable to keep pace with the evolving world..."

Mana poisoning was a perilous condition where individuals incompatible with mana were forcibly infused with it, their bodies disintegrating from the inside out as their DNA was utterly destroyed.

In the present era, even commoners and inanimate objects contain trace amounts of mana, rendering the 'mana poisoning' affliction extinct.

Yet, during the nascent stages of the Mana Descent, before humanity's acceptance by mana, countless individuals perished from this very affliction.

For those unreceptive to mana, this new, mysterious power posed a danger akin to 'radiation poisoning,' but amplified exponentially!

"The Nebo Civilization, unfortunately, was too deeply entrenched in the universe's former principles to adapt and achieve compatibility with new powers like mana and miasma..."

"Thus, like so many other civilizations, they met a grim fate... their people exploding from an overdose of mana, their bodies ravaged by conflicting 'laws' of reality going awry within them..."

"Their demise was both tragic and brutal..."

Raika met Rio's gaze, his voice now level.

"I was once a venerated saint of the Nebo Civilization; my foresight was deeply trusted, and people believed that with me among them, no harm would befall them, and their civilization would flourish indefinitely..."

"But life's path is often unforeseen... I bore witness as the very people I vowed to protect and guide met horrific ends directly before my eyes..."

"I could only stand by, powerless, as they brought their dying children to me for healing and salvation; I could only stand by, helpless, as I watched young ones whose parents had been violently vaporized into bloody pulp right in front of them..."

"I stood there, utterly incapable of intervening as parents witnessed their innocent offspring slowly decay into abstract forms within their very arms..."

Raika disseminated all his memories to Rio through his personal realm, the fidelity so profound that Rio could perceive every detail of the events on Planet Nebo with astonishing clarity.

The sheer horror of the massacre inflicted upon the Nebo civilization, solely due to their incompatibility with mana and their doomed inability to survive in the newly evolved world, caused even Rio to display a flicker of concern.

Despite his limited capacity for emotion, Rio considered it a profound shame that such a gifted race was annihilated so cruelly, denied the opportunity to showcase their potential to the wider universe.

'If individuals from the Nebo race were present on our planet... perhaps predicting the locations of future dungeon outbreaks beforehand would be feasible, thus preventing a multitude of disasters...'

It was a lamentable reality that such a possibility could not be realized.

"So, your ultimate objective is to resurrect your race?"

In response to Rio's inquiry, Raika shook his head.

"No. While I wish to see them revived, my people are fundamentally incompatible with mana and miasma; they cannot harmonize with the new rules governing this world..."

"Even if I discovered a means to restore their civilization, it would merely plunge them back into the same chaos they endured before...."

"Therefore, my true ambition transcends such a goal..."

With a grand gesture, Raika spread his arms, his gaze locking with Rio’s, as the surrounding landscape dissolved into the infinite expanse of the cosmos.

"All beings across the universe are either tormented by the influence of mana and miasma, or have already met their demise..."

"Mana and Miasma are alien 'forces' that invaded our world by coercion, Rio, and all they’ve brought is naught but death and ruin upon us..."

As Raika’s words unfolded, his tone grew heavy with gravity.

"Behold the sea of miasma; it has relentlessly devoured all in its path since time immemorial. And do not mistake mana for a benign, innocent power..."

"Much like my Nebo Civilization, it too has annihilated countless other civilizations that would have otherwise thrived in tranquility and flourished on their own accord..."

"Cast your eyes upon your own planet. Humanity was destined to be the sovereign of its world and solar system, yet now they are compelled to share resources with hundreds of alien races and are subjected to harassment by demons every few centuries!"

In a voice resonating with depth, Raika unveiled his ultimate aspiration to Rio.

"Should we succeed in purging mana and miasma from our universe, we can restore it to the pristine state of peace it once enjoyed!"

"The miasma covering the seas will vanish; the perpetual terror of dungeon outbreaks will be no more; the peril of overwhelming power falling into malevolent hands will be eradicated..."

"Furthermore, the universe’s blight, the demonic race, will also cease to exist!"

"And there is but one individual capable of accomplishing this monumental task, and that, Rio, is none other than you!"
