As the world was still in an uproar and countless cultivators were being organised and ordered by the old monsters in the Golden Core realm to find the source of nine coloured lightning, around 5 hours after Quetzalcoatl gained his new body and became Ao Xisu, he began to awake.
The Golden Core cultivator in the room with Quetzalcoatl had long since left, going outside to organise the rest of the cultivators under him, to prepare for the possibility of cultivators finding their temple and discovering the now freed Quetzalcoatl.
Sitting up slowly Quetzalcoatl, now Ao Xisu, inspected his new body internally, and once more felt a rush of elation.
"I truly have undergone a metamorphosis from Quetzalcoatl, beginning my effectively new life as Ao Xisu, it really is incredible the capabilities of this new body."
Inside his body he could sense his cultivation base constantly rotating, one of the effects of the satanic demonic vein he possessed was that it caused his cultivation base to constantly rotate, meaning he would always be taking in natural energy and cultivating, and with the refinement from the Eternal Stratum fruit this energy would always be perfectly purified, meaning without even needing to do anything Ao Xisu would be forming a perfect foundation and refining it further.
The only time it would stop was during a battle, and the constant rotation would resume five minutes after he finished fighting, however Ao Xisu wouldn't be cultivating normally during a fight so this was not an issue.
Looking further Ao Xisu noticed that he was truly at the very peak of the Foundation Establishment realm, and feeling his power he could sense... that he was even stronger than he had been in the past!
Even though he was only barely stronger than he had been in the past, this meant that at the peak stage of the Foundation Establishment realm he possessed power equivalent to that of an early stage Nascent Soul cultivator, this was unparalleled throughout almost the entire universe, and as far as Ao Xisu himself knew had never before been seen!
The combination of his heavenly nine coloured lightning bloodline, from the Heavenly Star Clan, which had used his Fuxi bloodline as a base, his own demonic bloodline, his incredible body formed from the War God's physique as a base fused with many incredible materials such as the Rage God's muscles and the organs and skeleton of many mythical beasts, along with the satanic demonic vein he possessed as well as the Eternal Stratum fruit, along with the Yggdrasil seed and the Jade Ocean eyes, all of these incredible elements had done the impossible and allowed a Foundation Establishment cultivator to not only have unparalleled talent, but also unparalleled battle abilities, able to fight a Nascent Soul cultivator.
Even in the wider universe when faced with cultivators from the ancient time of Earth or from the infinite void outside of earth, in deep space, Ao Xisu would still be considered an absolute peak talent, if not the greatest of all time.
Ao Xisu sat up fully and stepped off the platform.
Slowly walking, Ao Xisu walked slowly towards the exit of the cavern that had suppressed him as Quetzalcoatl for the last 4000 years of his life.
Having shed his old skin, Quetzalcoatl had effectively died in the cavern, and out of the prison that had sealed Quetzalcoatl, emerged Ao Xisu, a phoenix emerging from the ashes!
Coming to the entrance of the cavern, even with his 7000 years of life experience, Ao Xisu couldn't help but exhale slightly.
Taking a deep breath he walked towards the exit and stepped across the threshold... with no resistance whatsoever!
This time he let out a deep exhalation, followed by a laugh so raucous and joyous that it seemed as if no one had ever experienced such joy or happiness under the nine heavens.
"Freedom, I'm finally free, never did I think I'd actually escape this hellish prison before my death, let alone with such incredible prospects for the future as I have now, having a tenfold pillar Foundation Establishment cultivation, as well as the ability to fight early realm Nascent Soul cultivators. Life is looking up for me right now!"
However, at this time Ao Xisu noticed something slightly alarming.
As his cultivation base revolved, he found himself making progress so negligible, that even with how close he was to the Golden Core realm it would take him around 20 years to take that final half step.
This was already incredibly fast by the standards of the current earth, however it was middling at best compared to the talents of the ancient earth, when Ao Xisu had last been free and roamed the world, and Ao Xisu knew for a fact his talent was hundreds if not thousands of times better than the best talent he had ever encountered on Earth
Quickly he identified the problem.
As soon as his cultivation base rotated fully, back to his dantian where the nine lightning beasts formed from his bloodline obtained from the inheritance of the so called Heavenly Star Clan were residing, they would absorb over 97% of the energy.
The fact that he would make it to the Golden Core realm in 20 years, even with 97% of his cultivation base being effectively wasted with every rotation was in and of itself a testament to the talent Ao Xisu possessed.
Frowning Ao Xisu tried to figure out why his bloodline, which was not only a part of him but also supposedly incredibly powerful, would inhibit his progress to such an insane degree when it should be helping him.
Unable to come up with a reason for now, Ao Xisu decided to leave the temple first before people came to investigate where the nine coloured lightning had struck down, and many cultivators came to find him.
Even though with his power being around the early stage of the Nascent Soul realm, Ao Xisu didn't want to cause too many waves at the moment, but rather seamlessly integrate back into the world, since he knew that there might be other old monsters at cultivation levels even higher than the early stage of the Nascent Soul realm still alive and hidden in seclusion, even though there was no evidence of them existing right now.
Wasn't Ao Xisu himself the best example of an unknown Nascent Soul cultivator?!
"These people have served me well over the years, however I no longer need them. I don't want these people to let anyone know I'm free. As a reward for their service, I suppose I'll grant them a quick death."
The tempering of the years spent in imprisonment had made Ao Xisu realise even more the importance of being ruthless.
Unwilling to risk any chance of himself being imprisoned once more, Ao Xisu decided to test out the limits of his new body and its current power.
Revolving his cultivation base Ao Xisu burst straight up, penetrating through the multiple layers of the temple that he had been situated in.
His Golden Core subordinate sensed him doing this, and saw him floating in the air above the temple, gathering his power.
"Lord Quetzalcoatl I congratulate you on-"
Before the Golden Core cultivator could finish his sentence, he was pierced through the chest by a bolt of green energy, Void Qi produced by the {{Qiankun Heavenly Scripture}} that Ao Xisu cultivated.
"Its Ao Xisu, not Quetzalcoatl now."
Smirking, Ao Xisu gathered more power into his palms, forming a ball of pure Void Qi, even as his subordinate, speechless, collapsed from the sky, dying almost instantaneously from the energy that Ao Xisu had sent piercing through him.
With a maniacal laugh, Ao Xisu unleashed a blast of energy, so destructive that it instantly erased everything in the surrounding 10 kilometres, including all his terrified subordinates, and the mortals who had been in the area, still in shock from the nine coloured lightning from earlier.
"By the time those cultivators arrive they should think that this destruction was caused by the nine coloured lightning, and with the deaths of those subordinates of mine, I am truly free, no one knowing I was even here."
Having thought this far ahead, Ao Xisu, still truly a demon in his mind and actions, even if not in his body, disappeared from mid air, moving so fast he was invisible to the naked eye, even a late stage Golden Core cultivator would only barely be able to make out traces of his movements.
"Into the world once more I go, and I truly possess an incredible amount of power, I was able to instantly kill a late stage Golden Core cultivator with a single bolt of energy. My first aim will be to figure out why my bloodline is hindering my progress so much, and my first destination... why not New York City!"
Laughing with joy at being free Ao Xisu flew at incredible speeds, piercing through the air cruising at around Mach 2.
Around 10 minutes later when the first cultivators arrived at the scene of his imprisonment, which was now merely a basin around 10 kilometres wide and deep, Ao Xisu already long gone, formerly the devil god Quetzalcoatl, was once more free and roaming the cultivation world.
