At this moment, Sadius and Ignis were inside a sealed spherical space.
This spherical space could be described as vast—virtually boundless.
Yet from another perspective, it seemed small—within their perception, the sphere's diameter was no more than a hundred meters.
This was the strength of Hongmeng: with a casual wave, he had already reached the limits of the spatial laws.
The two of them sat cross-legged, meditating on their respective Edicts and Laws within the sphere as time slowly passed.
Who knew how much time had gone by when a strange energy fluctuation suddenly appeared before them?
A portal opened up in front of them.
"Let's go. This should be the way to another universe."
The two passed through the portal—and were greeted by a completely different scene.
"Sadius, this place is surprisingly similar to the Aether Supreme Overgod Realm you created," Ignis remarked as he gazed at the stars in the distance. But he quickly noticed that his voice wasn't transmitting, and so he switched to spiritual transmission.
"This universe…it's actually structured around planets!"
"Planets? You mean like your Aether Supreme Overgod Star?"
"Yes. Each of the planets here has 108 gravitational nodes. They vary in size—some are stars, some are terrestrial planets. Judging from the layout, this universe may very well be an interstellar civilization. Come, let's visit one of the nearby planets—perhaps we'll discover some of the lifeforms of this universe."
The two immediately began flying through space.
Given their strength as Overgod-level beings, their speed was simply unimaginable.
In the blink of an eye, they reached a planet within this star system.
"This is a gas giant—no signs of life here. Let's head to the next planet."
They proceeded to a nearby terrestrial planet.
This time, they detected signs of life.
"The core of this planet is nurturing a lifeform."
"Indeed. It's similar to the three-legged Golden Crow of the Aether Overgod Realm. But unlike that one, this planet is solid."
The two were intrigued. When would the lifeform at the planet's core hatch?
Generally speaking, beings born from planetary cores or elemental essences were at the very least Saint-level in the Coiling Dragon universe.
Of course, they had no idea how cultivation realms were structured in this new universe.
"Let's not disturb this unborn little one."
They departed once more.
"That star must be the main star of this system. It's radiating immense heat."
They looked toward the massive, blazing star before them.
"So in the eyes of the locals, that would be their sun?"
"Exactly. That's this star system's sun."
"What about the moon? Does this world not have a moon?"
Ignis wasn't familiar with the principles behind the sun and moon's operation. After all, the ones he had seen before were from the Coiling Dragon universe, whose structure was different from that of this universe's sun and moons.
"Perhaps that planet over there can answer your question."
They flew further.
Soon, they arrived at another planet.
"Look there—those are this planet's moons. And not just one, but three." Sadius pointed to the three satellites in the sky.
Ignis stared at the three moons, and a realization dawned on him.
"So those small bodies orbiting a large planet are called moons? This universe allows planets to have three moons?"
"Those aren't just small planets—they're satellites."
"Satellites?"
"Yes, bodies that orbit around planets are called satellites."
"This universe truly is unique."
The two left this star system and flew toward the next, continuing their exploration of this universe.
Just then, they sensed a fluctuation of the Heaven' laws descending on a planet in the distance.
The two immediately flew over to investigate.
On a terrestrial planet, a lifeform birthed from the planetary core soared from the depths of a deep-sea trench.
"Heavenly Tribulation? That's all it was? Today, I've endured my tribulation—I am the first being on this Hunyuan Star to achieve Immortality!"
The creature had once been a giant whale. After successfully transcending its tribulation, it immediately transformed into human form. Heavenly tribulations are equivalent to the descent of Heavenly Laws.
Ignis and Sadius watched the scene unfold from outer space, stunned by what they saw.
"An immortal cultivation system?" Sadius murmured, observing the newly ascended being.
There still lingered remnants of the heaven-and-earth laws—clearly, this individual had just survived their tribulation and ascended.
"Then in this world, becoming an Immortal after enduring the tribulation must be equivalent to a Saint reaching the rank of Lowgod in the Coiling Dragon universe."
Sadius effortlessly probed the memories of the new Immortal.
This giant whale had been the first lifeform born on this planet. Only after its birth did other life gradually appear.
From the moment it was born, it instinctively absorbed the world's energy. And in just five hundred years, it endured the tribulation and ascended.
As for the rest of the planet's inhabitants, most had yet to develop intelligence—let alone begin cultivation.
At that moment, a message echoed within both Sadius and Ignis's minds:
"Spread the Dao."
The two exchanged glances and nodded at each other.
It seemed Hongmeng had not brought them here just for sightseeing.
"Sadius, how exactly are we supposed to spread the Dao? Our cultivation is based on the magic system, which differs from this immortal cultivation path."
"In theory, the main universe should encompass all systems of cultivation. It's just that our universe originated as a magic-type subsidiary universe, and even after ascending to main universe status, it still only supports the magic system. However, we should be able to evolve other systems as well. Naturally, that includes this Immortal cultivation system. As long as I mentally simulate this world's cultivation path, I should be able to reconstruct its system."
Sadius immediately began calculating.
"In this world, cultivation begins by refining and absorbing the energy of the Heaven and Earth. So, the first realm would be Qi Refining, equivalent to a Rank 1 magical beast."
"After Qi Refining, the energy accumulates and liquefies in the dantian, strengthening the body and laying the foundation. That would make the second realm Foundation Establishment, equivalent to Rank 2 to Rank 3 magical beasts."
"The liquefied energy is then compressed into a solid form within the dantian, forming a golden core—much like a magic beast's magic core. That would be the Core Formation stage, equal to Rank 4 to Rank 6 magical beasts."
Sadius observed the cultivators on this planet. Aside from the one who had ascended, the rest of the lifeforms were only at the Core Formation stage. The next stage was not easy to determine.
From the memory of the Immortal whale, Sadius learned that after forming the golden core, the soul would begin to take form. The golden core would then melt into golden liquid and fuse with the newly formed soul.
Sadius felt this was somewhat similar to how a Saint-level magus in the Coiling Dragon universe would manifest their soul form.
But what shocked him was that after this soul formation, the being's strength surged dramatically—instantly rivaling that of a Saint-level existence in their home universe. This was far too strange.
"Could it be that the other cultivators hadn't yet reached the peak of Core Formation?"
"That's possible. After all, their strongest cultivators were only at the Core Formation stage."
Sadius swept his divine sense across nearby star systems and quickly discovered another life-bearing planet.
"I see. That fellow simply skipped an entire major realm."
"The fourth realm—where the soul takes form and merges with the golden core, transforming the core into an infant—I'll call this the Nascent Soul stage. Equivalent to Rank 7 to Rank 9 magical beasts."
"The fifth realm—where the golden core liquefies, fuses with the soul, and the soul undergoes a transformation—I'll call this the Spirit Soul stage. At this stage, one can begin to comprehend the laws of the universe. Equivalent to a Saint-level magical beast."
