One hundred and fifty-eight years later, less than five hundred years had passed since Ding Yun first announced to the world that she had attained the Dao and would preach on the twenty-fourth heaven of the Celestial Realm after one Yuan Hui.
Many with low cultivation were making their way to the Celestial Realm.
Some, indecisive and hesitant, had not yet decided whether to attend the sermon and had not yet departed.
However, due to a message Ding Yun had received earlier, she had to advance the preaching time and directly addressed the entire world through the Heavenly Dao network:
"Some time ago, while I was meditating in the Chaos, I unexpectedly discovered a group of Outer Realm Demonic Gods and Chaos Fierce Beasts were heading towards this world in large numbers. It is feared that the combined might of the entire world will be needed to resist them. Therefore, I must advance my sermon and begin by explaining the fundamentals to enhance the strength of all living beings for resistance.
If you wish to come to the Celestial Realm to listen, you may do so by silently reciting it. If you do not wish to come, you may remain where you are, and you will still be able to listen!"
After speaking, Ding Yun used the Heavenly Dao network to guide all beings who silently wished to attend the sermon in the Celestial Realm, placing them on the twenty-four heavens according to their cultivation realm. Ding Yun did not force those who did not silently recite.
In fact, if not for the emergency, Ding Yun would not have lowered herself in such a manner. She would have preferred to be more aloof like Old Ancestor Hongjun, whether they came or not was their own loss.
But now, with foreign invasion imminent.
If the world could not withstand it and was destroyed, even if she successfully completed her world-conquering mission, she would likely receive no origin essence rewards.
Therefore, she had to be a little more urgent.
Her actions did cause some gods, demons, Daoists, and ordinary beings to start murmuring, wondering if there was some conspiracy behind her eagerness to have them listen to her teachings.
Internally, they began to hesitate.
However, Ding Yun clearly did not have the time to consider what they were thinking. She only gave them one day and one night to decide. After that day and night, she would close the reception function of the Heavenly Dao network, ceasing to guide people to the Celestial Realm. Then, she would manifest her divine form to the entire world and begin her sermon.
Using the Heavenly Dao network, she began to preach the Great Dao, allowing all life in the world to listen if they wished.
She started from the most fundamental aspects.
How basic? As basic as the division of cultivation realms, the classification of Innate Spiritual Treasures, the grading of Innate Spiritual Roots, the differences in foundation and heritage, the distinction between innate and acquired beings, and so on.
Yes, it was that basic.
Before Ding Yun, this world did not have much of a hierarchical division. Cultivation was merely a matter of strength versus weakness. No one would say, "You are this realm, I am that realm." At most, some powerful individuals were classified as God-level or Ancestor-level. The term "Great Luo Immortal" was merely Ding Yun's designation.
Similarly, for Innate Spiritual Treasures and Innate Spiritual Roots, although there were specific differences in strength and function, no one had actually designated the number of Innate Restrictions or their respective tiers. No one had specified how many Restrictions would qualify an item as an Innate Supreme Treasure. Nor had anyone stated that a certain Innate Spiritual Root was top-tier and another was low-grade. At best, they might say the fruit from this Innate Spiritual Root was more effective, while that from another was merely for taste.
As for differences in foundation and heritage, or the distinction between innate and acquired beings, while everyone had an idea, there was no specific standard for classification.
What Ding Yun was doing now was to establish all the standards and give everyone a clear understanding, which would also facilitate her subsequent lectures on distribution of treasures.
After finishing these fundamental contents, Ding Yun still did not delve into grand theories like laws. Instead, she continued to discuss foundational cultivation methods, starting from how to refine Qi and how to transcend mortality to become an immortal.
Compared to the Three Tribes era, when Innate beings were everywhere and there were no acquired lives, the current world had begun to gradually generate Acquired Spiritual Qi and Acquired lives. These Acquired beings were different from Innate beings; they did not have long lifespans, nor were they born at the immortal level. They were much stronger than ordinary mortals in other worlds, but they could definitely not be called immortals. Even if these Acquired beings were given a million years, it was unlikely they would achieve much, let alone become the main force to resist the returning beasts of the Void.
However, Ding Yun still intended to include them.
After all, teaching how to become an immortal would not take much time.
After explaining the content on becoming an immortal, Ding Yun also incidentally taught how to reverse the acquired to innate, transforming oneself from an acquired being into an innate one, and how to improve one's foundation and heritage, evolving from an ordinary innate being into one with potential comparable to innate gods and demons. She even touched upon how to enhance the potential of innate gods and demons.
Then, she discussed cultivation after becoming an immortal.
Human Immortal, Earth Immortal, Heaven Immortal.
True Immortal, Profound Immortal, Golden Immortal.
The Five Energies Courtyard Yuan Tai Yi realm!
Three Flowers Gathering atop the Head Great Luo realm!
To complement her explanations, Ding Yun also disseminated tens of thousands of cultivation methods during her lectures. These methods had different levels of compatibility and adaptability.
Some were suitable for the vast majority of beings to cultivate, some were for those with special physiques, some were for beings with weaker foundations and heritage, and some could only be cultivated by those with profound foundations and heritage. In short, Ding Yun hoped that everyone could cultivate the method that best suited their situation and offered the fastest cultivation speed.
While teaching and explaining cultivation methods, Ding Yun did not forget to simultaneously impart methods for artifact refinement, alchemy, array formation, talisman creation, and other minor and major divine abilities, body refinement techniques, and so on.
In the beginning, when she was lecturing on fundamental content, many with higher cultivation realms were somewhat impatient, feeling that Ding Yun was merely fooling them.
These topics were of no use to them.
After all, the initial content Ding Yun spoke about was akin to a group of expert professors listening to basic addition and subtraction; few could listen patiently.
It was not until Ding Yun reached the Tai Yi realm.
And lectured on the seventy-two intermediate divine abilities.
That they truly focused their attention and listened intently with great interest. Later, upon hearing about the Great Luo realm, many gods, demons, and Daoists even began to switch to the cultivation path taught by Ding Yun, that is, the immortal path.
Of course, towards the end of the lectures, some with lower cultivation had completely lost comprehension. Ding Yun, at the appropriate time, directly shielded them, allowing them to focus on their cultivation and not to force themselves to listen to expert-level content with a primary school student's level of understanding, which would not only be unproductive but also damage their self-esteem and faith.
This continued for thirty thousand years. By the time several generations of acquired beings had died, Ding Yun finally finished explaining all the content up to the Great Luo realm.
She then relocated all beings currently in the Celestial Realm who had already reached the Great Luo realm to her Heavenly Dao Palace, where she began to give them specialized teachings.
This time, not everyone could hear her teachings; only those within the Heavenly Dao Palace could.
