The divine ability condensed at Yin Difference realm completion was like an ability naturally mastered from birth; without practice it could be used as easily as moving one's arm.
However, because Ren Qing's Method of Modeling Heaven and Earth was relatively special, if he did not actually use it, he truly could not determine the specific situation.
Ren Qing began arranging magical artifacts inside the cave dwelling to block the aura of techniques, in order to avoid accidental leakage when using the divine ability.
Once preparations were complete, he planned to start testing from the most superficial aspects.
Ren Qing could not help extending his right arm and communicating with the Ghost Wolf jailer inside Eternal Space Prison. Dense wolf fur immediately covered his arm, quickly completing a partial Ghost Wolf Transformation.
In the past when he transformed into a Ghost Wolf, he had to unseal the jailer from Eternal Space Prison, and then allow the strange object to merge with his body.
The process took at least several minutes, making it difficult to use at critical moments.
Now Ren Qing could easily make his arm complete Ghost Wolf Transformation through Method of Modeling Heaven and Earth, and it did not emit the slightest Ghost Wolf aura.
He did not stop there. Next his torso transformed into a Sand Man, while his left hand began growing black feathers similar to those of an Underworld Crow.
Within only a few breaths, five jailer characteristics appeared on Ren Qing's body simultaneously, and there was not the slightest conflict between the strange objects.
He said with interest, "Method of Modeling Heaven and Earth... truly interesting."
The so-called Method of Modeling Heaven and Earth was actually manifesting the things inside the world in the stomach onto various parts of Ren Qing's flesh body. The method appeared somewhat strange.
The jailerization of limbs was not possession by strange objects, but rather transforming his own arm from inside to outside into a Ghost Wolf arm.
Ren Qing looked toward his palm. At one moment the skin turned into soil from the island in Wine Lake; at another it displayed the patterns of the Dragon Tree trunk; at another it became high-temperature scorching volcanic rock...
This was only the tip of the iceberg of Method of Modeling Heaven and Earth.
In terms of potential, Method of Modeling Heaven and Earth absolutely did not lose to Dragon Roar Within the Casket. Jailer possession was merely the most basic method of use.
Ren Qing closed his eyes and began using Method of Modeling Heaven and Earth more carefully, preparing to merge magical artifacts into his body to see what mysteries it held.
The flesh on both his shoulders gradually changed, transforming into the material of stone and forming patterns similar to wall bricks.
Inside the Eternal Space Prison.
Han Li was patrolling on the southern city wall, accompanied by seven or eight cultivators.
Ever since Wuwei City had been taken into Eternal Space Prison, its danger level had drastically decreased, but the daily patrol inspections remained heavy.
At the beginning many cultivators competed to accept these tasks, but later they discovered that although the rewards were generous, the work was too boring.
Many cultivators would rather farm or refine artifacts than guard against nonexistent dangers and wander on the city wall for an entire day.
What they did not know was that this was a measure Ren Qing used to stimulate consumption in the dream market.
In any case, the resources of the Restraint Officers' Hall were sufficient to sustain several hundred or even a thousand years, so it was better to distribute resources to everyone as much as possible.
Unfortunately there were too few cultivators, even fewer than when the Restraint Officers' Hall had first entered Marshland. Market share had already determined transaction volume.
Han Li accepted the city-guarding task mainly because he wanted a quiet environment to think about the details of the aberrant fetus artifact refining method.
While he was distracted, the wall suddenly trembled slightly.
The other cultivators quickly gathered together and looked outside the city wall. Han Li frowned slightly and hesitated as he hid behind the crowd.
Originally, from the southern city wall one could see Wine Lake and the ten thousand mu of fertile fields at a glance.
Now dense mist had already enveloped the wall, causing the guarding cultivators to panic slightly. They hurriedly used bird-type strange beasts to contact Yin Difference realm cultivators.
Han Li quietly looked around and discovered that aside from the southern wall, mist had also abruptly spread outside the corresponding northern wall.
"Han Li, are you alright?"
Xiao San'er landed beside Han Li and stuffed a shield-shaped magical artifact used for protection into his hands. The two looked at each other with solemn expressions.
"I'm fine. What exactly happened?"
"This place is Senior Ren's world inside the stomach, why would..."
Han Li's heart sank. He could not help thinking of the worst situation, Ren Qing's main body might have encountered trouble.
Just as the city-guarding cultivators hesitated whether to retreat, an aura of Yin Difference realm approached.
Chen Haoyu arrived at the southern city wall with a limp. His newly grown elephant leg had not yet fully adapted, so walking was somewhat inconvenient.
The guarding cultivators immediately gained a backbone, and the commotion settled.
"Do not panic. I have already contacted Lord Ren Qing. There should be no problem... hm?"
Chen Haoyu had not even finished speaking before he froze, because the mist covering the two city walls slowly dissipated.
What appeared before them was a cave dwelling enlarged tens of thousands of times.
Han Li stepped back several steps. A head like a mountain appeared before him. The breath from its mouth and nose could even stir up hurricanes.
He noticed that the southern and northern city walls had somehow grown on the left and right shoulders of the head, while behind them remained Wuwei City.
The city wall was like a dividing line, allowing them to step into two worlds at the same time.
"Wait, it's Ren... Immortal..."
Chen Haoyu could not help blurting it out. Soon the other cultivators also noticed that the mountain-like head was clearly Ren Qing.
Ren Qing came back to his senses and spoke to reassure them.
"It's fine. No danger has been encountered."
His voice was deafening. Many cultivators with relatively low cultivation levels covered their ears at the same time.
The cultivators immediately relaxed. It seemed to be some kind of technique or divine ability.
Only its power far exceeded imagination, actually making them appear the size of ants.
Ren Qing had not expected such a situation either.
He had only intended to merge the city wall of Wuwei City with his flesh to obtain the amplification of a magical artifact, yet even the cultivators had been pulled out.
His shoulders had completely turned into city walls. More than a hundred cultivators stood upon them, curiously looking around at the furnishings of the cave dwelling.
"No wonder it's called Method of Modeling Heaven and Earth..."
Although his body had not grown larger, the cultivators summoned from the world inside the stomach had shrunk countless times. In comparison he became a gigantic being.
Ren Qing shook his shoulders and carefully examined the cultivators, discovering that they did not feel the shaking of the city wall.
His expression became strange.
It seemed that cultivators manifested on the city wall through Method of Modeling Heaven and Earth did not have their cultivation weakened and remained at their original realm.
Ren Qing communicated with Han Li through consciousness, signaling him to perform a technique.
Han Li looked confused, then spat out an arrow feather as black as ink. It flew straight out of the range of the city wall and struck the rock wall.
The rock wall immediately formed a dent, and the corrosion from Nether Yuan sizzled.
However, Han Li's cultivation was far inferior to Ren Qing, so he only created an inconspicuous pit, yet clearly the power of the technique was unaffected.
Ren Qing showed joy. The divine ability Method of Modeling Heaven and Earth was truly terrifying.
He could fully manifest Wuwei City in his flesh body, allowing thousands of cultivators to help fight enemies, essentially turning him into a humanoid artillery platform.
If the population of Eternal Space Prison increased further, the power of the divine ability would naturally rise as well.
If the several hundred thousand people in the Longevity Forbidden Zone were included...
Ren Qing did not dare continue thinking. When the world inside the stomach reached Yang God realm or even Heavenly Aberration realm, the divine ability would produce even more changes.
He then began testing Method of Modeling Heaven and Earth.
Ren Qing wrapped the city wall on his shoulder with ghost shadow. With a slight sting, the wall immediately cracked open, yet the inside still revealed rock.
The cultivators were startled, thinking they had encountered an unknown powerful enemy.
After Ren Qing canceled Method of Modeling Heaven and Earth, the city wall returned intact to Eternal Space Prison, while only a shallow wound remained on his shoulder.
The wound healed within a few breaths.
This meant that even if the city wall manifested on his flesh body were damaged, it would not harm Wuwei City inside Eternal Space Prison.
Ren Qing attempted to use ghost shadow to perform Method of Modeling Heaven and Earth. After all, ghost shadow could also be considered a part of himself, but this time it failed very decisively.
The reason was likely that ghost shadow's connection with Eternal Space Prison was relatively shallow. Perhaps he would have to wait until Yang God realm when the divine ability became complete before trying again.
Overall, Ren Qing was very satisfied with Method of Modeling Heaven and Earth.
Unfortunately it did not solve the fundamental problem. Eternal Space Prison still could not connect to the Longevity Forbidden Zone through it, and the efficiency of lifespan extension remained difficult to improve.
While stabilizing his cultivation, Ren Qing used the dream seed outside to observe Heaven Above Heaven.
No matter what, he still needed to refine flesh puppets. If he missed the opportunity in Heaven Above Heaven, it would take at least several decades of accumulated lifespan to allow Eternal Space Prison to advance to Yang God realm.
How to proceed required careful discussion.
Ren Qing soon calmed down. It was better to finish refining the flesh puppet first; otherwise all ideas were empty talk.
He soaked the dead egg of the Heavenly Dao Insect in blood according to the formula given by Li Yaoyang, adding activated materials one by one.
In the end he obtained a Heavenly Dao Insect egg. The larva inside clearly displayed vitality, but it was still a soulless dead fetus.
Seeing this, Ren Qing took out a pseudo soul and glanced at the flesh furnace. The Fuel King had already nurtured a second pseudo soul.
However, he did not know if it was his illusion, but the newly born pseudo soul seemed more solid and contained noticeably less malice.
Ren Qing continued nurturing the split souls of the Fuel King using Other Shore Flower.
However, considering that Heavenly Dao Insect eggs were non-regenerable resources, he would at most refine five flesh puppets, making it less likely to be exposed.
Ren Qing did not choose to follow the method recorded in the Facing-the-Moon Method but instead took a shortcut.
The same applied to refining Broken Moon Meteor. A pseudo soul barely counted as a complete soul, so the difficulty was certainly far lower than using remnant souls.
He divided the pseudo soul into strands and gradually merged them into the Heavenly Dao Insect egg.
The Heavenly Dao Insect began to move, but it gave an extremely unstable feeling.
Ren Qing did not wait for it to change and directly began engraving complicated Moon Patterns, since the purpose was to refine an artifact soul.
He removed from the original Rabbit-Toad Broken Moon Meteor all Moon Patterns related to releasing demonic qi and increasing intelligence, leaving only a blank template.
With the cooperation of ghost shadow, Ren Qing spent more than a month.
The final product was a twisted lump of flesh with extremely weak consciousness, fundamentally unable to serve as the soul of a Rabbit-Toad.
But it was enough for Ren Qing.
He used Dragon Roar Within the Casket on the Broken Moon Meteor, completing pseudo-dragonization, and then hid within it a dream seed containing demonic qi.
The dream seed was originally the one belonging to the split soul, but because he had mastered eye-pupil related body techniques, he simply destroyed it and Ren Qing nurtured a new one.
The moon-core pseudo dragon looked like a flayed lizard, with a mouth occupying one-third of its body, filled with sharp fangs.
Ren Qing played with the Broken Moon Meteor pseudo dragon. Now he only needed the right moment.
