Immortal cultivation starts with copying.

That blood-red stone is called Earth Blood Crystal Stone, meaning a stone formed from the convergence of the earth's blood.

Blood Essence Immortal Grass can only be produced where this kind of stone exists, so the growth conditions of this Blood Essence Immortal Grass are extremely demanding.

However, after ten thousand years, the energy of this blood crystal stone was almost exhausted; otherwise, the blood essence herb would not have withered to this extent.

Chen Yunhao thought for a moment, then took out a small glass bottle.

It contained a blood-red liquid, which was the essence blood that Chen Yunhao extracted after slaying demonic and divine beasts.

The essence and blood of this demonic beast are extremely valuable; at the very least, they can be used to refine immortal talismans.

He opened the bottle and poured the essence of the demonic beast onto the Blood Essence Herb.

Don't be fooled by the fact that this small glass bottle is only the size of a palm; it contains a whole universe inside, with at least several hundred kilograms of demonic beast essence blood.

As the essence blood of the demon beast was slowly poured onto the Blood Essence Immortal Grass, the essence blood gradually disappeared.

Then, the Blood Essence Immortal Grass slowly began to glow with a faint blood-red light, and then gradually began to stand upright.

Half an hour later, the Blood Essence Immortal Grass stood up completely, but its branches and leaves were still drooping and had not fully recovered.

Judging from this situation, the fact that it has not yet recovered to its full strength does not mean that the efficacy of the Blood Essence Herb is much weaker.

Of course, if Chen Yunhao were to use the Blood Essence Immortal Grass now, it would still have some effect, though perhaps a little less.

He understood that as long as he devoured this Blood Essence Immortal Grass, his cultivation level would immediately advance to the late stage of Earth Immortal.

However, it wouldn't make a difference to wait a little longer. He needed to collect more demon beast blood essence to restore the Blood Essence Immortal Grass to its peak condition.

Then use the Blood Essence Herb, making sure to use it to its fullest potential.

Chen Yunhao carefully stored the Blood Essence Immortal Grass into the Qiankun Tree space and placed it under the Qiankun Tree.

The Qiankun Tree is the ancestor of all spiritual plants in the world, and the vibrant life force emanating from it is also beneficial to the growth of the Blood Essence Immortal Grass.

Chen Yunhao then returned to the small space via the teleportation array. The next step was to decide whether to keep or leave the small space.

The conclusion he reached with the artifact spirit remains the same: this small space has begun to show flaws, so there's no need to leave it.

Even though it's a small space, with most of the ground belonging to spirit fields, so what? Compared to the Qiankun Tree space, it's nothing at all.

Chen Yunhao had already cultivated a large area of ​​spiritual fields within the Qiankun Tree space, where he had planted all sorts of spiritual herbs and immortal medicines, totaling nearly a thousand acres.

Those were various spiritual herbs and elixirs he had collected and accumulated throughout his life, most of which were collected from the lower realms and are now basically useless.

Chen Yunhao stood outside the courtyard wall and tapped repeatedly with his hand. The courtyard slowly began to tremble, gradually detaching from the ground and rising into the air.

Then it shrank instantly, turning into a stream of light that landed in Chen Yunhao's hand.

This little courtyard is quite exquisite. Chen Yunhao plans to put it in the Qiankun Tree space and use it as his own private courtyard.

Then, a spatial fluctuation suddenly appeared above Chen Yunhao's head, and a huge spatial void slowly appeared.

From that void, one can see the lush and verdant world of the Qiankun Tree; the spatial devouring has officially begun.

Chen Yunhao then flashed back into the Qiankun Tree space.

Although this small space is not large, it will not be something that can be completely devoured in a short time.

Anyway, Chen Yunhao wasn't in a hurry, so he sat cross-legged in the Qiankun Tree space and slowly observed the merging of the two spaces.

This is also a rare opportunity for him to comprehend the power of space.

The opportunity for two spaces to merge, regardless of size, is rare; some cultivators may never witness it in their entire lives.

The merging of the two spaces lasted for more than half a month, and Chen Yunhao did not intervene in it; he did not yet have the ability.

Everything is a natural activity of space, a normal behavior of big fish eating small fish.

Chen Yunhao hadn't slept a wink for half a month, yet he showed no signs of fatigue; on the contrary, his eyes grew brighter the more he looked.

Because the prototype of another spatial path has already taken shape in his mind, and once he fully comprehends it, his spatial law power will increase by another level.

After the Qiankun Tree space devoured the smaller space, its area increased by several hundred miles.

This fusion is not an advancement of the Qiankun Tree, but merely a spatial fusion, so there is only an increase in area, but not much.

After the spaces merged, Chen Yunhao returned to the outside world.

He was still at the same valley where he had settled, but it was already daytime.

However, another problem arose because he had set up two restrictions in the valley before entering the space.

Someone is attacking the barrier now. After all, he has been in the space for some time, and there are quite a few cultivators coming and going in this Ancient Demon Mountain Range.

So it's not surprising that the restrictions in the valley were discovered.

Because he set up the barrier himself, he could see what was happening outside from the inside.

Outside were two cultivators at the Immortal Realm, one in the early stage of Earth Immortal and the other in the middle stage of Earth Immortal; one was older and the other younger.

The one who made the move was a young cultivator in the early stage of Earth Immortal, while the older immortals stood aside with their hands behind their backs watching the show.

The restrictions set up by Chen Yunhao were, of course, immortal arrays, so even if an immortal attacked, they wouldn't be able to break them in one or two hits.

Clearly, the two cultivators outside had only recently discovered it, and the damage to the restriction was not significant.

Chen Yunhao glanced at it silently. This kind of thing was common and not uncommon in the cultivation world.

They haven't taken action yet; they're just figuring out the timing and consequences.

If I don't intervene, these two restrictions will be broken sooner or later.

Furthermore, he himself is only at the mid-stage of Earth Immortal, and he is not entirely confident in facing the two immortals from the outside world.

Of course, his overall strength is greater than that of an ordinary immortal, but he has no idea how much stronger he is.

Since arriving in the Immortal Realm, he has always acted cautiously and prudently, except for some battles with celestial beasts.

He has almost never fought against immortals of the same level, so he still has some hesitation in his heart.

He didn't have much time to think. Chen Yunhao was able to cultivate to the Immortal Realm, which meant he was a decisive and ruthless person.

He simply pointed upwards, and the two arrays burst forth with a burst of white light.

Then, a loud bang was heard, and the entire valley shook. Even the eagle beak rock that jutted out from the top of the valley collapsed.

This was the first step; Chen Yunhao detonated two immortal formations.

He doesn't care at all; he can replicate as many as he wants anytime. He can afford to wait.

The two people who were attacking the immortal formation were slightly startled, especially the young cultivator.
