The Root of Myriad Mother Qi was incredibly heavy; the moment it appeared, it filled the entire small world.
In the original story of Cover the Heavens, when Ye Fan first came into contact with this item, his cultivation realm was far too low, and he simply could not move it.
Even a single wisp of Myriad Mother Qi could have crushed Ye Fan to death.
The reason he was able to move it was because he had obtained a fragment of the Immortal Ascension Cauldron.
The bronze fragment of the Immortal Ascension Cauldron had proactively helped him absorb the Root of Myriad Mother Qi.
Now, Zhang Daoyuan’s cultivation realm could be considered that of a Quasi-Emperor, and he had already traveled quite far within the Quasi-Emperor realm; one could say he was nearing the level of a Great Emperor.
Zhang Daoyuan could feel that he was approaching the ceiling of this Sacred Body.
"Hmm?"
Zhang Daoyuan had intended to put away the Root of Myriad Mother Qi and refine it into a weapon.
But before he could act, he suddenly noticed a slight anomaly.
The Root of Myriad Mother Qi before him was becoming heavier and more unique.
At first, Zhang Daoyuan thought it was an illusion, but in an instant, he dismissed that thought.
Because it was real.
With his current level, which was that of a Quasi-Emperor nearing the Great Emperor level, he could easily perceive it.
It was not an illusion; the Root of Myriad Mother Qi was absorbing the rules between this Heaven and Earth and becoming stronger.
To describe this feeling, it was like moving from a small world into the Nine Heavens and Ten Lands, or arriving in the Immortal Realm.
Then, it began to undergo sublimation.
Zhang Daoyuan was not unfamiliar with this situation.
Some small worlds created by True Immortals were isolated from the world, and the associated rules were not as formidable as those of the Nine Heavens and Ten Lands.
In such small worlds, individuals at lower realms could possess destructive power at higher realm levels.
Staying in such a place for a long time allowed one to experience the destructive power and the levels of a higher realm in advance, making it easier to achieve a breakthrough after leaving.
However, in such small worlds, the associated medicinal materials and treasures would be downgraded, or rather, the ceiling was not as high as in the Nine Heavens and Ten Lands.
The top-tier medicinal materials in the Nine Heavens and Ten Lands could reach the True Immortal level—they were Immortal Medicines, and there were even medicinal materials at the Immortal King level.
But in a world created by a True Immortal, the highest-level medicinal materials could basically only reach the level of Divine Medicine.
No matter how unique they were, reaching this level was basically the limit.
Even if the seed of an Immortal Medicine were to fall into a small world, it would have no way of becoming an Immortal Medicine.
But once it was taken out of such a small world and came into contact with the Great World, receiving the baptism of the Great World's rules,
then its original essence would be revealed.
As long as it did not die or collapse during this process, it would naturally undergo sublimation and become an Immortal Medicine.
It might even undergo an even more precious metamorphosis.
This situation was also reflected in the original story of Perfect World.
The overall Heaven and Earth level of the Eight Regions of the Lower Realm where the Desolate Heaven Emperor stayed was not high enough, and the Heaven and Earth limit was very low.
But that did not mean the ceiling for the people living there was also low.
When they came from the Lower Realm to the Upper Realm, to the Nine Heavens and Ten Lands, and to the Three Thousand Dao Provinces,
they would undergo a baptism of Heaven and Earth rules.
Then, during this process, their physical bodies and Nascent Souls would undergo sublimation.
It was not just them; even the medicinal materials brought up from the Lower Realm would undergo this process.
If they could withstand the intense baptism of the Heaven and Earth rules, these medicinal materials would grow further.
Their potential would be stimulated, allowing them to reach a higher level.
Although many medicinal materials and people would be unable to withstand the baptism of the Heaven and Earth rules and would suddenly die during this process,
as long as they could withstand it, they would undergo intense change and intense sublimation.
The batch of medicinal materials that the Desolate Heaven Emperor brought up from the Lower Realm had experienced this stage of sublimation.
And now, the Root of Myriad Mother Qi in Zhang Daoyuan’s hands was also experiencing this stage.
"Hmm?"
After perceiving this, Zhang Daoyuan was instantly filled with great surprise.
He even stared closely at the Root of Myriad Mother Qi, watching it change.
Then, Zhang Daoyuan felt even more.
The change was intense but stable, because the Root of Myriad Mother Qi itself was the most top-tier treasure between Heaven and Earth.
Furthermore, the quantity he had was extremely large, making it extremely stable.
Even if a few wisps occasionally could not withstand it and shattered, more Myriad Mother Qi was being born, and the Root of Myriad Mother Qi was also undergoing sublimation during this process.
In this instant, Zhang Daoyuan thought of many things.
The future Nine Heavens and Ten Lands was like a small world, with the ceiling being the True Immortal level.
It was even the case that they could not reach the True Immortal level; the true ceiling was the Great Emperor level.
Once one reached the Great Emperor level, there was basically no path forward.
Those who could reach the Mortal Immortal realm were all exceptionally gifted individuals.
If placed in this current era, those who could achieve the Mortal Immortal realm in the Post-Desolate Ancient Era would be able to achieve the Immortal King level here steadily, with no issues at all.
Even those who achieved the Great Emperor level were the most peak Heavenly Prodigies in that era.
In this era, they could achieve the True Immortal level; as for higher levels, I dare not say, because Zhang Daoyuan’s current realm is not yet that high, and I cannot make such a judgment.
But Zhang Daoyuan could determine that a Great Emperor from the Post-Desolate Ancient Era could achieve the True Immortal level here.
That world was still the current Nine Heavens and Ten Lands, but the overall world specifications and the world ceiling had been lowered by one level.
It was just like the Great World and small worlds in this current world.
Therefore, taking things from a small world into the Great World meant that sublimation was basically a certainty, provided one could withstand it.
In the Immortal Ancient era, the Root of Myriad Mother Qi could be used to forge Immortal Artifacts, and it could even be used to forge the embryos of Immortal King Artifacts.
Because the ceiling of this era was higher.
It was just like how the Immortal Gold of later eras could basically only forge Great Emperor weapons, but in this era, it could forge Immortal Artifacts.
Take Yellow Dao Immortal Gold, for example; this special Immortal Gold was basically identical in description to the Dao Tribulation Golden of the later Post-Desolate Ancient Era.
In this era, that Immortal King who was severely injured outside the Border Pass alongside the Second Under Heaven,
and whose Nascent Soul went missing, leaving only his body behind, was formed from this Immortal Gold becoming sentient.
His mount, that Golden Divine Ox, was also formed from Yellow Dao Immortal Gold becoming sentient.
Once a Sacred Spirit of this era was successfully gestated and born, it was a True Immortal.
Whereas in the Post-Desolate Ancient Era, the period where Ye Fan, Emperor Ye, lived, a perfect and flawless Sacred Spirit born into the world was only at the level of Alternative Dao Attainment, not even a Great Emperor.
They still needed to perform the Ultimate Leap to become an Emperor and be invincible under Heaven.
It was the same world, but because the world had been subjected to continuous wars, the ceiling had constantly dropped, revealing a very large gap.
And now, Zhang Daoyuan had brought the Root of Myriad Mother Qi from the Post-Desolate Ancient Era into this era with a higher ceiling, so the Root of Myriad Mother Qi was reviving once again between this Heaven and Earth.
In the Post-Desolate Ancient Era, Myriad Mother Qi alone could forge an Ultimate Emperor Weapon, and the Root of Myriad Mother Qi was the embryo for an artifact at the True Immortal level.
It could be used to forge an Immortal Artifact.
But in this current era, Myriad Mother Qi could already forge an Immortal Artifact, and the Root of Myriad Mother Qi could forge the embryo of an Immortal King Artifact.
When Zhang Daoyuan realized this, he was suddenly overjoyed.
The Dao Scripture contained the concept of "one artifact breaks ten thousand laws"—refining a single weapon, and "after I bloom, a hundred flowers die."
And the Boundless Profound Scripture of the Sea of Realms similarly contained the most top-tier artifact refining methods.
Right now, this artifact embryo had not yet completed its final sublimation, so Zhang Daoyuan was still able to refine it.
Without any hesitation, he immediately began to refine the weapon.
