Within the Great Dao Saint Realm of the Five Elements Heavenly Dao World, with that Great Dao Holy Mountain as the center, the entire Great Dao Saint Realm had expanded to a radius of 50,000 li at this time.

This area, in the true Five Elements Heavenly Dao World, is still just a drop in the ocean.

However, after all, it only belonged to the Great Dao Saint Realm, and it was already more than ten times that of an ordinary Great Sage Immortal King late-stage immortal, and it was even bigger than the Holy Emperor's.

Of course, this is only the Great Dao Saint Realm, not the Heaven and Earth Realm that is truly a realm of its own. The real realm of heaven and earth is able to accommodate living beings to survive and cultivate within it, such as the three realms of heaven and earth that the Dragon Emperor showed in front of him at the beginning.

There were three realms of heaven and earth that the Dragon Emperor showed him in the imperial capital. The spiritual domain that was tempered when the Holy King was tempered, the divine domain that was tempered when the Holy Emperor, and the immortal domain that was tempered when the Holy Emperor.

These three major heaven and earth realms, under the operation of the Dragon Emperor's Great Dao Saint Realm, have become a complete system of their own, and even the creatures within them have their own complete cultivation system.

The path that Wu Yan took to refine the Heaven and Earth Realm was not the same as the Dragon Emperor, and even different from anyone in the Hongmeng Three Realms and the Heavens and Ten Thousand Realms.

At the time of the Ancestral Immortal and the Yuan Immortal, he did not refine the Spiritual Domain, and when he reached the Saint King Realm, he naturally did not have the Heaven and Earth Spiritual Domain, and besides, in the Saint Emperor Realm and the Saint Emperor Realm, he did not plan to refine the Heaven and Earth Divine Domain and the Heaven and Earth Immortal Domain.

He has only one goal, that is, to refine the Great Dao Saint Realm until it can withstand the Great Desolate Saint Yuan Mountain, and then use his Great Dao Sacred Mountain to fuse the Great Desolate Saint Yuan Mountain and make it become the World Mountain of his own Heaven and Earth Realm, and then it is the time for him to truly refine the Heaven and Earth Realm.

This was the way he began to refine the Heaven and Earth Realm after he learned that the Great Wilderness Saint Yuan Mountain was actually a World Mountain obtained by the Five Elements Great Heavenly Venerable from the Great Wilderness Metaverse.

Possessing the Heaven and Earth Realm as soon as possible, for ordinary immortals, the advantage is that they can comprehend the Heaven and Earth Dao more quickly, and then comprehend the ethereal Heavenly Dao.

Comprehending the Great Dao of Heaven and Earth through the realm of Heaven and Earth, and then getting a glimpse of the Heavenly Dao, this is the cultivation path that ordinary immortals must take if they want to break through the Supreme Immortal Venerable, and even the Heavenly Venerable, but for Wu Yan, this is dispensable.

With the unique condition of the Great Wilderness Yuan Ding, especially the Great Wilderness Yuan Ding that was opened, as long as he can comprehend all the nine realms of Hongmeng, the nine heavenly realms within it can be used by him, and Wu Yan has no need to waste time on refining the heaven and earth realm in advance.

Wu Yan had carefully thought about the matter of the Five Elements Great Heavenly Venerable, with his ability, he could not be immortal, and finally fell into the dark tribulation, so if he wanted to preach eternity, he was afraid that it would not work to follow his old path.

And the key to preaching lies in the understanding of the Tao. As the foundation of the Dao, the role of the Dao Saint Realm will undoubtedly be more crucial.

Why did the Five Elements Great Heavenly Venerable get the Great Wilderness Saint Yuan Mountain from the Great Wilderness Metaverse in the first place? I'm afraid it has something to do with the foundation of the Dao. Perhaps it was precisely because the Dao foundation of the Heavenly Dao Sacred Mountain that he had refined before was not enough to preach Dao Chaos, let alone Dao Eternity, that he fell.

The Great Wilderness Shengyuan Mountain can be regarded as the most important treasure collection by the Five Elements Great Heavenly Venerable, and what it means is self-evident.

From the mouth of Gu Yao Lao Dao, Wu Yan has sporadically known the ultimate fate of some of the Heavenly Replenishment Descendants, and therefore understands why Gu Yao Lao Dao gave up becoming the Heavenly Replenishing Descendant.

According to Gu Yao's old Tao, with the help of the Great Wilderness Yuanding, although the heirs of Mending Heaven can easily comprehend the Hongmeng Heavenly Dao, and even become the Hongmeng Great Heavenly Venerable, they must ultimately sacrifice their own Dao to achieve the Hongmeng Holy Spirit.

According to Gu Yao's old Dao's understanding, sacrificing one's own Dao is no different from sacrificing oneself, without the Dao, even if the Dao is Hongmeng, or even the Dao Chaos, what is the use, in the end, it is not to fall and disappear?

The reason why Gu Yao Lao Dao has such an idea is also related to his failure to open the Great Wilderness Yuanding. After opening the Great Wilderness Yuanding, Wu Yan realized that things were not as simple as Gu Yao Lao Dao said.

Panzu's ultimate goal, since he wants to merge the Meritorious Heavenly Dao with the Hongmeng Heavenly Dao and restore the Chaotic Heavenly Dao, and even wants the Chaotic Heavenly Dao to also fuse the Dark Heavenly Dao and restore it into a more primitive and powerful Heavenly Dao, this kind of Dao Wu Yan guessed as the Eternal Heavenly Dao, then this sacrificial Dao is naturally not the Hongmeng Heavenly Dao as Gu Yao Lao Dao guessed.

And as the successor of the Heaven Replenishment who carries the mission of the Great Wilderness Yuanding, in the process of completing the mission, he will undoubtedly gain unimaginable benefits from it, that is, he will be able to get a glimpse of the Chaotic Heavenly Dao that has never appeared in the Hongmeng Immortal Realm, and even the more primitive and ancient Eternal Heavenly Dao!

If it is true that the Tao is eternal, is the sacrifice really a sacrifice?

This question, in terms of Wu Yan's current realm, is impossible to know, and naturally it is impossible to answer. However, he felt that the mystery in this could not be as simple as Gu Yao Lao Dao understood.

Looking at the Great Dao Holy Realm, due to the appearance of the Great Dao Holy Mountain, the entire Holy Realm had undergone earth-shaking changes, and the corners of Wu Yan's mouth showed a satisfied expression.

Late Saint King, how long has it been? It's been less than a day since the last time he broke through to the early stage of the Saint King, and he actually broke through two realms in a row again, reaching the realm of the late Saint King.

Even if it weren't for the fear of attracting the attention of the merit holy spirit, causing the shock of Situ Bofeng and others on the side of the merit pool, and letting go of the suppression of the holy source breath in the Great Dao Holy Mountain, I was afraid that if I sucked up the merit source in the merit pool, it would be possible to impact all the way to the Holy Emperor realm.

If today's Tao is occupied by merit, Wu Yan breaks through the realm, and he will no longer accept the baptism of the great tribulation of heaven and earth like before.

Of course, Wu Yan naturally understood what was going on with the original Immortal Tribulation now.

The ancient beasts in the Sea of Returning Ruins stole and absorbed the power of the Heavenly Dao in the Three Realms of Hongmeng through the Eye of the Sea of Returning Ruins, resulting in a deficiency in the Heavenly Dao.

In order to eliminate this kind of incompleteness and allow the immortals in the Three Realms to grow up normally, it is understandable that the Heavenly Dao sent down the immortal tribulation for refining.

Those who can't survive the immortal tribulation, or die in the immortal tribulation, I am afraid that it is also due to the inability to make up for the defects and hidden dangers.

Crossing the Immortal Tribulation is a phenomenon that only exists in the pseudo-realm, in the real realm, there is no immortal tribulation at all, only the Dao Tribulation, a Dao Tribulation that will occur once in an era.

As long as you can cultivate to the True Immortal Realm and survive in the True Realm, then as long as the Dao Tribulation does not come, the True Immortal will not fall, this is the real Immortal.

However, in a place like the True Realm, how could ordinary True Immortals survive?

At least as far as Wu Yan can see, in the true realm, the lowest cultivation is also the Immortal Venerable, and the immortals under the Immortal Venerable are generally cowering in the Star World or the Holy City, and they don't dare to go out at will.

Now, the Holy Spirit of Merit and the Holy Spirit of Darkness have set the land of the Heavenly Dao within the Three Realms of Hongmeng at the same time, which has also caused countless immortals in the True Realm to fall to these two Holy Spirits to pour into Xuantian one after another, breaking the peace and balance of Xuantian at once.

With a heavy exhalation, Wu Yan's gaze fell on a few plants on the edge of the Great Dao Saint Realm.

The largest of them is naturally the Soul Nourishing Ancestral Tree, of course, it is obviously not appropriate to call it the Soul Nourishing Ancestral Tree at this time.

Due to the opening of the Great Wilderness Yuan Ding, the chaotic qi that had not yet dissipated in this world also appeared in the Nine Great Realms, and it was inevitable that it would be absorbed by these plants in the Five Elements Heavenly Dao World.

The Soul Nourishing Ancestral Tree had already returned to its roots by absorbing the Qi of Chaos, and had become a Netherworld Divine Tree.

If it weren't for the fact that the chaotic qi it had absorbed was still too small, and it was only a few zhang high at the moment, I was afraid that within this Five Elements Heavenly Dao world, there would be earth-shaking changes.

After all, the Netherworld Divine Tree represents the Netherworld Heavenly Dao among the Nine Realms of Hongmeng.

This divine tree is naturally also the key that Wu Yan will use to open the Netherworld Heavenly Dao World in the future.

The other Divine Tree, which was slightly taller than the Netherworld Divine Tree, had a faint moonlight overflowing on it, and it looked extremely sacred and quiet.

This tree is the Laurel Divine Tree that Wu Yan grew up by absorbing the chaotic qi after implanting it in the Five Elements Heavenly Dao World with laurel seeds.

To be honest, Wu Yan was also a little puzzled by how this laurel divine tree could sprout and grow in the Five Elements Heavenly Dao World. After all, when Wu Yan got the laurel seed, he learned that this tree could only grow if it was planted on the Taiyin leyline.

However, he couldn't figure out the reason, so Wu Yan naturally had to attribute it to the chaotic qi.

Next to the Laurel Sacred Tree, there is a plantain sacred tree. To be honest, when Wu Yan first obtained the withered banana immortal root from the secret realm of the Spirit Ruin Land, he didn't expect that it would be resurrected one day.

It was only when Wu Yan later saw that this plantain immortal root fell into the Five Elements Heavenly Dao World, and almost in just a few days, it recovered as it was and grew into a mature plantain divine tree, he realized that this plantain divine tree was eighty percent of the original collection of the Five Elements Great Heavenly Venerable.

Of course, in addition to these three plants, what Wu Yan liked the most was actually the Chaos Divine Tree that was only a few feet tall and had always looked a little wilted.

This tree is naturally also cultivated from Chaos Seeds, but other Divine Centers can grow quickly by absorbing Chaos Qi, but this tree has not changed significantly.

In fact, among the Great Wilderness Yuan Ding, there was a fifth plant, that is, the Bright Divine Tree in the Bright Heavenly Dao World.

At the beginning, in the Desolate Ancient Heavenly Dao World, most of the seeds of the Bright Divine Tree collected by the Great Wilderness Yuan Ding had turned into the power of the Bright Heavenly Dao, dispelling the Hongmeng mist within it, and only one of them had turned into a real Bright Tree Species, and absorbed the chaotic qi in it, sprouted and grown, and became a sapling a few feet high.

Except for the saplings of the Bright Divine Tree that were not affected by Wu Yan and grew inside and outside the Bright Heavenly Dao World, the saplings of the other four Divine Trees were actually all in the Five Elements Heavenly Dao World opened up by Wu Yan's Great Dao Saint Realm.

Although the appearance of the Great Dao Sacred Mountain did not affect them, it squeezed out the middle ground they originally occupied.

To Wu Yan's surprise, they seemed to be quite disdainful of Wu Yan's Great Dao Sacred Mountain, looking at the situation, if it weren't for the endless Hongmeng mist around them, they would not even want to stay in Wu Yan's Great Dao Holy Realm after this Great Dao Holy Mountain appeared.
