Judging from the information obtained from refining the seed of Hutian's magical power, it can be roughly divided into five levels according to the characteristics of different spaces.

The first stage is the lowest level of unstable space. Storage rings and storage bags at the magical instrument level are essentially this type of space.

The duration of unstable space can be as short as several decades or as long as hundreds of years. Due to its own unstable characteristics, it will eventually collapse after reaching its limit.

The second stage is the independent space. The courtyard space where Shen Yuan is located and the cave opened up by ancient great monks belong to this type.

The independent space has a relatively stable spatial structure, and with the circulation of internal and external spiritual energy, it can support living things and last for hundreds of years.

The third stage is called the secret realm. This type of space is often attached to the Xuanhuang Realm. It already has the rudiments of a certain paradise, and some special secret realms even have independent rules.

A secret realm can often exist for thousands of years, but if it encounters a period of spiritual energy depletion, the imperfection of the secret realm's own internal rules will lead to the loss of spiritual energy and eventual collapse.

The place where Prince Jidu died was a ruined secret realm, and it was precisely because of the secret realm that he had the opportunity to seal his broken soul into the dragon ball and survive.

The fourth stage is the blessed land, which is often born under extremely special conditions, or is a broken part of a certain world, or is derived from a special treasure.

The blessed land exists in the Xuanhuang Realm. It has its own rules that are very different from those of the Xuanhuang Realm, forming a small world of its own. As long as it is not affected by external forces, it can almost exist forever. The only flaw is that it can only exist in a fixed space.

After the exhaustion of spiritual energy, a blessed land would attract countless practitioners, as only by entering a blessed land could one survive the period of spiritual energy exhaustion.

Of course, there are differences in strength among the blessed places. The powerful blessed places listed among the 72 blessed places can naturally stand firm in the era of spiritual energy depletion, but some small blessed places outside the 72 blessed places will often collapse due to the various influences brought about by the spiritual energy depletion period.

After several eras of spiritual energy depletion, the number of blessed lands remaining in the Xuanhuang Realm is now extremely scarce.

The fifth stage is naturally the cave heaven above the blessed land.

The blessed land can be transformed through some treasures, but there is almost no channel to the cave heaven except those opened up by earthly immortals and left over from the upper realm.

And after the connection between heaven and earth was cut off, the connection with the upper realm was severed, so the value of the cave heaven was naturally more precious.

The biggest feature of the cave heaven is that it can escape into the void and is no longer confined to a certain space. Its internal rules are also more perfect than those of the blessed land.

During the heyday of the ancient cultivation world, the masters of the cave-heaven sects would often spend thousands of years transforming the cave-heaven. Each cave-heaven was inlaid with tens of millions of formations, which would turn into an incomparably terrifying war machine once activated.

The so-called human Taixu ship is just a fragile little toy in front of Dongtian.

The Hutian method mastered by Shen Yuan points directly to the path of earthly immortality. If one practices to the peak, he can open up a paradise, but that is something that can only be achieved after one has achieved true immortality.

For Shen Yuan at this stage, having an independent space is already a pleasant surprise, not to mention that this cave order has the opportunity to help him improve the courtyard space into a secret realm.

Holding the cave order in his hand, Shen Yuan chose to use it without hesitation.

The spatial rhythm of the cave was spreading quietly. Shen Yuan could clearly see that the independent space of the courtyard was like a ball of soft plasticine being stretched by an invisible big hand.

Under the influence of that big hand, the scope of space began to expand continuously around, and the originally unstable space structure gradually formed a fulcrum that depended on the Xuanhuang Realm, thereby stabilizing this space.

Shen Yuan watched the changes in space intently. His Hutian magical power was activated, and his divine consciousness began to extend outward to capture the spatial rhythm of the cave order.

Following the rhythmic changes in the spatial level, Shen Yuan suddenly felt an extremely familiar feeling in his heart.

"Wait a minute, why does the spatial rhythm emanating from the cave order look so much like the Hutian magic power?"

Shen Yuan was suddenly startled, and all his thoughts were poured into capturing the rhythm of space. Following the slight changes in the vibrations of space, Shen Yuan began to subconsciously operate the Hutian magical power.

"No, it's not enough!" After only a preliminary imitation, Shen Yuan immediately felt the inadequacy of his own spiritual power. It was difficult for him to capture the deep rhythm of space.

With a firm heart, Shen Yuan took out the ice-condensing fruit that he had received from Lord Fubolong from his storage ring.

The ice fruit exposed to the air showed a faint strange phenomenon, and hexagonal snowflakes kept floating in the air.

As a fruit that can promote the cultivation of Yin God, Ningbing Fruit itself has great benefits on the soul level.

The most correct way to use Ningbing Fruit is to refine it into medicine.

However, at this stage, there are almost no alchemists in the cultivation world who can refine elixirs for the Divine Transformation Realm. In addition, the opportunity to comprehend the Hutian Divine Ability is rare, so Shen Yuan has no choice at all.

Shen Yuan took a bite of the condensed ice fruit. The flesh seemed fresh and juicy under the thin ice. After swallowing it, it immediately turned into a stream of clear water and quickly flowed into Shen Yuan's spiritual platform.

The blurry fake soul was bathing in the clear stream. Its blurry figure gradually became clearer, and the divine consciousness in its spirit center also grew stronger.

After swallowing the Ningbing Fruit in a few bites, only the core was left. Shen Yuan's spiritual activity had reached its peak.

Not daring to delay for a moment, Shen Yuan immediately used his spiritual power to control Hu Tian's magical power and imitate the rhythm of that space.

The breakthrough in his spiritual consciousness finally allowed Shen Yuan to capture the changes at the spatial level, and the expansion speed of the courtyard space began to accelerate.

At this moment, Shen Yuan also understood one thing, that is, why the hidden reward for becoming the leader of Luoyun Sect is the Hutian Divine Ability.

This is because this Hutian magical power was most likely from the great earthly immortal from the Luoyun Sect who was trying to lead the entire sect to ascend to heaven.

The great earthly immortal controls Luoyun Cave, and this cave order was also made by him to seal the Hutian magical power, so Shen Yuan was able to sense the power of the Hutian magical power from it.

Time passed slowly, and after dozens of minutes, the effect of the cave order had reached its limit, and the black token in Shen Yuan's hand was covered with cracks.

As the expansion of the courtyard space came to a complete halt, the space began to re-freeze, and the cave was shattered into pieces.

At this time, the courtyard space was widened by more than ten times. Although its size was not outstanding, it was even smaller than the caves of some ancient great monks.

But in terms of the spatial hierarchy, this courtyard is already a complete small secret realm. Even if the area is hundreds of times larger than the courtyard, it is still far from comparable to it.

Sitting upright in the house, Shen Yuan's eyes still retained the changes brought about by the rhythm of space, and his pupils turned into pure silver-white.

Those mysterious rhythms kept repeating in Shen Yuan's mind. After being baptized by the Ningbing Fruit, his mind kept trying to imitate the changes in space.

The cave order came from the creation of a powerful earth immortal. Although it was most likely just a casual work, the level of the Hutian magical power displayed in it was far beyond Shen Yuan's cognition. Any tiny detail was enough to bring great inspiration to Shen Yuan.

After several minutes, the silver-white color in Shen Yuan's eyes finally subsided.

Before Shen Yuan made any movement, a weak spatial fluctuation descended into the room.

The next moment, the space changed, and Shen Yuan appeared directly in the courtyard.

In his palm, the crystal clear seed of Hutian magical power dimmed again, and a large amount of information poured into Shen Yuan's mind like a tide.

Hu Tian's supernatural power has reached the level of mastery!
