After the realm of gods was destroyed by Spinosaurus aegyptiacus, the world of emptiness once again gave birth to a Phoenix from the primordial chaos fire bound to the boundary between the 12th dimension. Then, a dragon born from pure primordial chaos from the existence of the gods that had perished.
The Phoenix absorbed the entire existence from pure chaos fire; it was born from nirvana and returned to nirvana. Continuously, it tried to break through the door to the 13th dimension through nirvana repeatedly.
Even though newly born into the world, it had already undergone 103 nirvanas from level 10 to reach level 90. To break through to level 100, it had to undergo nirvana 150 times without rest.
On the other hand, the pure primordial chaos dragon did not need to undergo nirvana; it was not an existence like the Phoenix that could continuously reborn through nirvana. Whereas the pure primordial dragon only needed to absorb pure primordial energy and undergo the laws of the 13th dimensional heaven to enter the 13th dimension. Currently, the pure primordial chaos dragon had reached level 90, just like the Phoenix.
Whether Phoenix or Dragon, they were the first existences after the gods perished when they were eradicated by Spinosaurus aegyptiacus named "The Only One."
Phoenix continuously absorbed the ancient chaos fire, then underwent nirvana again. Each time it underwent nirvana, Phoenix required 1 year to reach a higher hierarchy.
Every nirvana, Phoenix would obtain different divine abilities each time it underwent nirvana again; sometimes obtaining the same ability, but it would stack into one, increasing understanding of that ability as nirvana time progressed.
After experiencing 106 nirvanas, Phoenix had obtained 106 divine abilities, such as the ability to control time, return after death as Phoenix, manipulate ancient chaos fire that can easily burn low dimensions, continuously evolve without limits, and dozens of very powerful divine abilities.
On the other side, the pure ancient chaos dragon, after raising its level to 96 with the heavenly laws of the 13th dimension, obtained a multitude of divine abilities like manipulating space-time in the 12th dimension, manipulating life and death, manipulating paths of karma, fate, and cause and effect, and manipulating every change in events.
Far at the edge of the 13th dimension, the giant Quetzalcoatlus named "Who Terrorizes the Sky" was breaking through to the 14th dimension. Its giant beak would even pierce the highest chaos when Quetzalcoatlus headbutted the 14th dimensional wall with its beak.
The gleam of Quetzalcoatlus's wings was extremely majestic; every movement of its wings would sweep away the entire river of time, all multiverses in the 14th dimension with disaster winds that even blew away chaotic winds from the void.
In dimension 12, Phoenix and the Dragon have reached level 99, where they continuously raise their levels to ascend to level 100 and evolve into the "Ancient Super Divine Beast Phoenix and Ancient Super Divine Beast Dragon."
Phoenix continuously absorbs the ancient chaos fire to undergo the final nirvana and reach level 100, while the dragon absorbs all pure ancient chaos to undergo the heavenly tribulation of the 13th dimension to ascend to level 100.
For 5 long years, Phoenix and the Dragon continuously absorbed until they finally reached the boundary between level 99 and level 100. After that, Phoenix flew into the chaos sky, breaking into the chaos fire and undergoing level 100 nirvana, while the dragon, after touching the level 100 boundary, immediately flew to the heavenly laws to experience level 100 lightning tribulation and evolve.
10 years passed. Phoenix rose from death after undergoing nirvana and reached level 100. On the other side, the dragon had also reached level 100 after undergoing the heavenly tribulation of the 13th dimension.
After reaching level 100, Phoenix and the Dragon simultaneously attacked the wall of the 13th dimension. Phoenix unleashed "The Fire of Primordial Chaos" that can burn everything, even capable of burning existence itself. The dragon attacked with "Pure Primordial Chaos Lightning" that can incinerate all reality into ashes.
After breaking through the 13th dimensional layer wall, Phoenix and Dragon stood frozen when they saw hundreds, thousands, millions of "world bubbles" destroyed chaotically, as if attacked by something.
Phoenix said, "It's possible that something happened in this 13th dimension that we don't know about." Dragon replied, "That might be true, but what kind of existence could wipe out all these 'world bubbles' like mere toys?"
Phoenix said, "Possibly something extremely powerful passed through here." Dragon responded, "However, those 'world bubbles' are clusters containing infinite multiverses, and there are billions to trillions of 'world bubbles' destroyed chaotically here."
After that, Phoenix and Dragon flew exploring the entire chaotic trajectories of the irregular "world bubbles."
Along the trajectory, Phoenix and Dragon saw all laws vanished, time became fragmented garbage without memory, even space could no longer contain what wasn't worthy of being called space.
At the edge of the 13th dimension, Quetzalcoatlus had broken through the 14th dimensional layer wall until it shattered and entered it at incomprehensible speed. It continued flying above the "world bubbles" of the 14th dimension, destroying all time trajectories and realities of the 14th dimension, making all "world bubbles" irregular.
On the other hand, after that, Phoenix and Dragon moved quickly until they reached the edge of the 13th dimension and saw that the 13th dimensional layer wall had been destroyed. Phoenix and Dragon didn't waste the opportunity and broke through the already destroyed 13th dimensional layer wall, entering the 14th dimension.
After Phoenix and Dragon entered the 14th dimension, they saw something enormous flying above all the "world bubbles," destroying all those "world bubbles" just by passing through them.
However, Quetzalcoatlus, sensing that something was following it, stopped moving and looked back.
Phoenix and Dragon, upon seeing Quetzalcoatlus's physical form, immediately trembled uncontrollably, their bodies unable to move.
Quetzalcoatlus roared loudly toward Phoenix and Dragon, instilling fear in them just with its roar and intimidating gaze.
Quetzalcoatlus unleashed an overwhelmingly dominating aura that shook the entire core of the 14th dimension just by emitting a fraction of its physical body's aura. That alone was enough to absolutely flatten all reality existing in the 14th dimension.
Phoenix and Dragon knew they couldn't fight Quetzalcoatlus even with their level 100 power. Despite being only level 30, Quetzalcoatlus was completely beyond their reach.
Unable to fight Quetzalcoatlus, Dragon and Phoenix fled far away and retreated into the 13th dimension. After that, Quetzalcoatlus turned around and continued flying toward the 15th dimension.
