The Yin God of the White Sun Holy Mother furrowed its brows in pain at this moment.

In its abdomen, it felt as if thousands of sharp spikes had been thrust in, continuously draining its strength.

It could sense that Yu Ziqing's resistance was unexpectedly intense.

It also noticed Yu Ziqing's madness in layering defenses.

Furthermore, it sensed that Yu Ziqing was attempting a reverse possession.

Yet, there was nothing it could do but first deplete the runes and halos around him.

As the reverse possession began, Yu Ziqing siphoned off a significant amount of power and simultaneously seemed to glimpse the entire life of the White Sun Holy Mother.

Scenes unfolded before him, and he followed them backward, seeing the moment the White Sun Holy Mother first descended and called his name.

He also saw the simple life of an ordinary herdsman boy before the Holy Mother descended.

Until this life ended, the scenes faded away completely.

Yu Ziqing continued to intensify his force of siphoning, racing against time.

The white radiance around him dimmed slowly, and his layers of defense depleted by the thousands.

After depleting two thousand layers, he finally broke through the darkness and delved into the White Sun Holy Mother's past memories.

As he devoured the White Sun Holy Mother's Yin God, he followed the remembrances rushing back into the past.

He saw the previous time the White Sun Holy Mother was killed by him and witnessed him suffering twice from the backlash of the hungry ghost's incense power.

Once when devouring the incense power and once attempting to condense incense power into an incense fire crystal.

He saw his previous descent into Bai Gou's body.

Incessantly devouring, he relentlessly pursued the memories into the past.

Darkness reemerged, while Bai Gou's lifetime reached its initial starting point, and moments later, yet another thousand layers of defense vanished.

The scenes brightened as if playing in reverse.

He saw a massive blaze, flames filling his vision.

All around were elites of the White Sun Evil Cult, burnt alive within the flames until their forms and souls were obliterated, turning to nothingness.

Continuing in reverse, he saw an old man standing atop a large rock, book in one hand and pen in the other, with a stern expression, gazing coldly at the White Sun Evil Dao.

Indeed, it truly was that old Yang fellow.

He was the one who executed the trap slaughter of a group of White Sun Evil Cult leaders, and saying he didn't know the White Sun Evil Cult was nonsense.

He proceeded to move backwards along the scenes, witnessing scenes as if played in reverse.

The White Sun Holy Mother's lifetime after lifetime drifted past him, and he seemed to stand there, watching coldly.

He devoured more and more power and simultaneously saw more and more of the past, growing increasingly clear and immersive.

It was as though he were personally on the scene, witnessing the time when the White Sun Holy Mother advanced to the Ninth Tier, encircled and slain by numerous Ninth Tiers.

Gradually, Yu Ziqing became immersed in it, understanding more and more.

He felt he was about to uncover the true origin of the White Sun Holy Mother.

The layers on Yu Ziqing's Yin God grew fewer.

The White Sun Holy Mother's Yin God grew weaker, yet its eyes shone ever brighter.

It already sensed that Yu Ziqing's reverse possession and the speed at which it devoured his Yin God couldn't keep up with the rate at which those defensive measures crumbled.

However, the White Sun Holy Mother didn't notice that its brilliant aura-emitting Yin God had dimmed completely.

The purely white Yin God had been infiltrated by blackness, much like ink drops slowly staining its Yin God.

This was also one method to guard against possession, buying time to disperse its own Yin God and parasitically hide within the other's Yin God, preventing complete possession.

As time unfolded, ten full days passed before Yu Ziqing's amassed twenty-thousand-layered defenses completely dissipated.

At this moment, the other Dharma Methods Yu Ziqing cultivated that couldn't be layered began to take effect one by one.

His Yin God gradually began to melt, as if turning into black water, merging into the White Sun Holy Mother's white Yin God, slowly turning it entirely black.

But in the perspective of the White Sun Holy Mother, it had devoured Yu Ziqing's Yin God, fully integrating it into its own Yin God, and replaced it.

Yet, it didn't feel any memory from Yu Ziqing.

Logically, after completely devouring a Yin God, even Yu Ziqing's past memories should've been consumed, with those fragments naturally surfacing.

Yet now there was nothing at all, and Yu Ziqing's consciousness seemed to have vanished.

Yu Ziqing's consciousness had already, through the scenes, fully embedded itself into the past.

He stood there, as if the entire world was retreating, revealing everything that had once belonged to the White Sun Holy Mother.

He could hear the chirping insects and singing birds, as if he were physically present, experiencing all the White Sun Holy Mother had once touched.

Lifetime after lifetime.

He had nearly forgotten how many times the White Sun Holy Mother had descended.

In yet another life, he saw the White Sun Holy Mother being tormented by a faceless individual for an entire lifetime.

In the next life, it was the same individual, tormenting it.

It happened five times in a row.

Only then did Yu Ziqing understand why the White Sun Holy Mother feared nothing, as it had previously endured far worse.

The pain and torment accompanying its prior removal from possession paled in comparison to what this ruthless individual put the White Sun Holy Mother through for several lifetimes; it couldn't even be considered a nuisance by comparison.

Continuing from that lifetime, Yu Ziqing then saw something entirely different from before.

This wasn't where the Three Divine Dynasties were located; the powers there, the mountains and rivers there, were completely different from the land beneath his feet.

Initially, the White Sun Holy Mother wasn't from this land at all and was merely an outsider.

This was quite different from what Yu Ziqing anticipated, although, in essence, it was rather similar.

Yu Ziqing himself was a transmigrator, so understanding through personal experience, he was well aware that should he continuously arrive in this world, lifetime after lifetime, over undetermined eons, no one aside from himself could ever trace back his true origins, let alone before his transmigration.

Thus, Yu Ziqing also realized that he could not trace the origins of the White Sun Holy Mother back to its beginnings.

To thoroughly kill the White Sun Holy Mother, he had to obtain information from the Holy Mother herself.

And the method of obtaining such information was just like this.

Continuously diving in, continuously backtracking, seeking the initial starting point.

…

On the ground, the White Sun Holy Mother opened its eyes, with a calm expression tinged with a trace of joy.

Liu Xin hastily stepped forward, untying the bindings and removing the Soul Suppressing Nails.

"Congratulations, Holy Mother, felicitations, Holy Mother!"

The White Sun Holy Mother moved its body, feeling its immense strength, and couldn't help praising,

"What a powerful physique, what a powerful hungry ghost Yin God."

"It even developed seven hundred and twenty orifices, how did it manage that?"

The White Sun Holy Mother inspected the body, sensing the Death Prohibition Rune on its left arm, wanting to touch it only to be directly repelled.

The rune, of unknown origin, simply didn't allow it to touch.

However, it could vaguely sense it was likely tied to the power of the Hungry Ghost Dao.

The possession had a flaw; it occupied the body and devoured the Yin God, yet it failed to acquire any memory.

The crucial awareness core, whether it shattered or vanished, was entirely unperceived in the end.

"Holy Mother, the hungry ghost is ready, and it requires..."

"No, tend to the injuries first." The White Sun Holy Mother firmly declined.

It cherished this body immensely now; any hidden hazard, any injury, needed to be healed first before stabilizing the Yin God.

Its Yin God, now turned pure black and somewhat indistinct, appeared akin to a hungry ghost form yet didn't quite fit. It intended to wait a while longer.

Having succeeded, there was no rush at the moment.

It browsed through Yu Ziqing's Storage Bag, finding only Spirit Jade, some low-tier Dharma Method Jade Scrolls, and the rest being miscellaneous books on various local customs and cultures.

Then there was the rusty sword.

It was certain that the last time Yu Ziqing killed it, Yu was undoubtedly below the Fourth-tier, but at that time, he wielded this sword and unleashed Fifth-tier strength.

Yet, after researching for a long while, the sword appeared to be just an ordinary rusty sword without any remarkable power.

Having failed to acquire Yu Ziqing's memories, it didn't know how to unleash its power.

It could only slowly investigate it.

…

Everything around grew increasingly vivid, and Yu Ziqing already felt as if he genuinely existed in this world—not merely a bystander anymore.

He could even alter his perspective, viewing everything outside the scenes within the White Sun Holy Mother's memories.

He felt he was nearing the initial starting point.

Because he saw this life of the White Sun Holy Mother cautiously hidden in a remote, small mountain village.

One by one, slowly brainwashing the mortal villagers.

In this little village, it stayed for thirty entire years, accumulating Fourth-tier power, only then daring to take its first step.

And that first step was merely to another village.

The world continued its retrospection, and this life ended, leading to prolonged darkness and void.

This time the duration was especially long.

After an unknown length, light reappeared.

And this time, the world that emerged did not feature the White Sun Holy Mother.

It was someone else.

Following this person, Yu Ziqing saw deities sitting lofty above the nine heavens, with the slightest displeasure bringing down divine punishment.

He saw temples scattered all around, statues of deities everywhere.

He witnessed how everyone had to spend a large portion of their time each day laboring to survive, before entering temples to offer worship, treated as mere machines contributing meager wish power, even having to buy their incense candles.

The land was strewn with corpses, the populace left to die in despair.

The nobles serving deities received abundant incense fire crystals to support their cultivation.

He also saw that Qi Refiners who did not cultivate with incense fire crystals were treated like rats, persistently hunted if they dared reveal themselves.

The view belonged to an ordinary civilian.

Like everyone else, he labored hard to fill his belly, and once completed each day, he went to the temple to buy some expensive incense candles for his family's daily task of serving the gods.

Without any particular changes, his life might have continued like this, day after day, until his death.

But change came.

One day, he saw a deity, high above, emanating divine light, surrounded by flames, fall from the sky to the ground.

The deity's screams were even more harrowing than the pigs slaughtered in the village.

The impact of this scene finally added a flicker of change to his previously numb gaze.
