SCIV was winning, until she insulted the most powerful demon in history and lost
(Seeing those GoT X character was winning until Y trend as of late I'm making this for RI characters).
Star Constellation immortal venerable was without doubt one of the smartest venerables, with Fate gu around and fused with HW, HC was unstoppable, until her era was over and LDV's was starting that is.
SCIV made the mistake of insulting the most powerful venerable in history a Rule path venerable! Telling him that he couldnt destroy Fate gu even if he wanted to!.
A venerable who lived all his life bending, rewritting and bypassing rules as easily as he took a breath was told by an old crone, from a bygone era that no matter how hard he cultivated, anything he tried on fate gu would be pointless!
This was without doubt SCIV's lethal mistake, she could've cultivated taking into account the possibility of Fate gu being eventually destroyed, thus picking a better specialty path than Star to get ahead and protect HC if need be, instead she arrogantly doubled down believing her plots superior to those of other venerables.
That mistake cost her everything, LDV left HC pissed off and more than ready to plot to destroy fate gu! With the right pawn of course!
Next RSDV came to HC, what did SCIV do? Tried to deceive the venerable of transformation path into a scam deal she had no intent to backing up if it actually destroyed fate gu, in adition later many HC gu immortals adopted strength path, robbing from one of the manliest Demon venerables in history.
One would think two demon venerables coming to HC's doorstep was a sign the righteous path was falling into decadence, SCIV didnt take it into consideeration, humans were still on top while VHs were slaves, until RLDV's Dao guardian Duke Long's Dragonman transformation had created a dilemma for HC, this new race of Dragonmen could last so much longer than the Average human lifespan decreasing the need for lifespan gu, in adition if one could turn mortals into dragonmen without wasting dao marks, then they could harvest Enslavement path dao marks from them!
But SCIV was righteous and had to win all the time, this meant no compromises! Who cares about improving the cultivation prospects of the gu world? Who cares about increasing the lifespan of humans with this method so they could benefit? They were all Slaves of Fate anyway! And so SCIV gave Duke Long carte Blanche to go ahead and dispose of his entire family and ruin the best lifespan extension and transformation method in history!
And what did SCIV ended up with at the end? A weakened HC, with many gu immortals stuck on dead end paths like Strength and Qi! She had to support the poor bums she crippled with her poor decisions, her righteous arrogance still strong! The Demonic path still growing! Even CC's sects were beginning to be swayed by the demonic path!
Then Gue Yue Fang Yuan came along, he was backed by every venerable immortal or demonic, SCIV had insulted out of HC with her hubris, could cultivate every path in creation! He destroyed HC's immortal graveyard, fate gu, slaughtered countless Gu immortals from CC, even achieved the Rank of Venerable in refinement path using a VH's refinement true meaning inheritance! SCIV was furious! This Gue Yue Fang Yuan openly mocked every righteous being that existed in gu world and he did it with a demonic smile that made her realize too late what she failed to realize in millions of years, that while she had been playing chess with LDV over Heaven path dao marks in Crazed demon cave the righteous path was falling and the demonic path was rising! He had spent 3 million years plotting on her, giving SSDV's SiF's recipe, his entire Eternal life obcession ingrained in FY, SCIV expected righteous slavery and lost to demonic liberty.
