Ren Qing's consciousness transformed into an illusory human form and arrived at the Prison Within the Abdomen.
He walked along the corridor outside the cells, his gaze sweeping across the Supernatural Remnants inside one by one, causing constant howling sounds to ring out.
Ren Qing actually felt some regret in his heart.
Previously, because the Prison Within the Abdomen was simply too narrow, he had not deliberately collected Supernatural Remnants, which led to the number now being not many left.
Ren Qing now had relatively little choice.
For the time being, it was also impossible to go to the Ghost Market, after all, the Great Dream Arcane Path had already closed. If he were to activate the shop with the Butterfly Dream Technique, it would be a bit too early.
He could only try to select from the existing Supernatural Remnants, examining the cells again and again, the atmosphere growing more and more silent.
The Supernatural Remnants seemed able to sense malice. Unlike their usual irritable state, they all hid in the corners without moving, fearing to be discovered.
The Ghost Wolf and the Kunpeng let out strange whimpering sounds, seemingly mourning their fellow kind like foxes grieving the death of a hare, but in reality mocking those of their kind locked inside the cells.
Ren Qing inspected the Supernatural Remnants for a long time, yet still was not very satisfied.
Although he did not understand much about the use of the Eerie Fetus, it could be assumed that the type of Supernatural Remnant would indirectly affect the magical tool.
But it was also hard to say, after all he had to first try to use the Eerie Fetus to refine a magical tool.
Ren Qing walked out of the corridor. His eyes swept unintentionally across the Kunpeng in the corner, and his brows suddenly twitched, making him scrutinize it.
Speaking reasonably, the Kunpeng Supernatural Remnant was indeed very suitable for the sandboat. Its potential when pushed to the extreme of aberration was already sufficient, but the problem was...
Could the Jailer really be stripped out?
The Kunpeng instantly sensed danger, a chill spreading down its spine throughout its whole body, making it unable to keep from being frightened and uneasy.
It was unlike the Sand People, so stupid that all they did every day was swallow Ze Sand and then sleep.
It was also unlike the Ghost Wolf, which, as a Jailer, had confidence, thinking that as long as it did not provoke Ren Qing, there would be no danger to its life.
Although the Kunpeng's intelligence was not considered high, it also knew the principle of being at the mercy of others, especially after hearing those tragic screams from the Supernatural Remnants.
It tried its best to hide in the shadows, wanting to make itself less conspicuous.
The malice in Ren Qing's eyes grew increasingly dense, but then he shook his head and walked away.
Whether the Jailer could be stripped out was another matter; the Eerie Fetus Refining Method had not even begun yet. If the refining method could be easily figured out, it would never have come down to someone like him, a cultivator in the Yin Runner Realm.
Ren Qing fiddled with the Eerie Fetus, feeling the aura inside it gradually weaken. It would not be long before it turned to ashes.
Ren Qing took out the magical robe he had refined during his leisure.
The result was not like the dragon bone's violent commotion; the two coming into contact produced no reaction.
But when he took the Eerie Fetus outside, the sandboat once again stirred restlessly. The dragon bone's desire to devour the Eerie Fetus grew ever more impatient.
"Could it be that the sandboat's situation cannot be replicated?"
"It shouldn't be, right..."
Ren Qing suddenly recalled that, because of the Lord of Absolute Darkness before, the dragon bone had undergone an unexpected change.
As a magical tool it had no soul, but the dragon bone did possess an instinctive consciousness.
This could perhaps be the key to the Eerie Fetus Refining Method.
After deep thought, he did not choose to forcibly use the Lord of Absolute Darkness.
If one had to rely on the power of a certain technique, then the Eerie Fetus Refining Method would have no meaning to be spread, appearing far too useless.
But Ren Qing already had a rough direction, so there was no need to remain entangled.
He directly placed the magical robe onto the Tombstone Furnace, and once the human skin as the main material was activated, he used various materials to attempt to stimulate the magical tool's consciousness.
Ren Qing originally held no hope. If all the existing materials ended in failure, then he would simply wait until after he controlled the Ghost Market to try again.
But the result was that, when he smeared Ze Sand, the robe underwent a change.
The remnant soul within the Ze Sand wanted to merge into the robe, causing the magical tool itself to resist fiercely.
Just as the robe was about to self-destruct, an extremely faint consciousness was born.
To call it consciousness, it was more like a wisp of resentment, far inferior to the sandboat's dragon bone.
Ren Qing stopped his hand in time. Though the robe was battered and in a bad state, at least it was not destroyed, and the resentment still remained.
Immediately he felt the robe want to devour the Eerie Fetus.
Without hesitation, Ren Qing tossed the Eerie Fetus to the robe. At once the human skin extended countless tendrils, tightly binding the Eerie Fetus.
Ren Qing observed extremely carefully.
He felt that there should be a complementary relationship between the magical tool and the Eerie Fetus, which had led to the birth of such an unusual refining method.
The raw material of the magical tool was taken from a cultivator, while the Eerie Fetus was a dead Supernatural Remnant.
Shouldn't they both count as having the same origin?
Ren Qing waited quietly, hoping that the first Eerie Fetus Tool could be born smoothly.
The robe gradually produced many mysterious patterns, wriggling as if breathing, as though it wanted to once again transform into a Supernatural Remnant.
Ren Qing raised his vigilance, using ghost shadows to wrap around the Tombstone Furnace.
The Tombstone Furnace was, after all, the foundation of his standing as master of the Ghost Market.
The robe magical tool stabilized, unconsciously giving off the aura of the Restraint Officer Method.
Ren Qing furrowed his brows. Why did it look like a soulless cultivator puppet?
"Could it be that I've refined some kind of freakish thing..."
Just as this thought arose, the robe suddenly went wrong. Blood kept seeping from its surface, the stench of rot spreading out.
Ren Qing hurriedly pulled the robe away from the Tombstone Furnace, then threw it into the corridor.
Bang!
A strange noise rang out.
The robe transformed into a human skin, actually walking upright for a few steps.
But not long after, the magical tool itself began to collapse, the signs of rotting growing worse, black blood spraying from its pores.
Bang!!!
The magical tool turned into minced flesh, black blood splattering the walls and floor.
Ren Qing's face was uncertain.
But after weighing the gains and losses, he felt he was not far from success.
The Eerie Fetus was a beast-like Supernatural Remnant, while the robe magical tool was of human skin material, the huge disparity making further fusion impossible.
Without much hesitation, Ren Qing continued to work on refining.
Fortunately, within the Prison Within the Abdomen, Supernatural Remnants and materials related to the Divine Leg Sutra could be gathered into several sets, showing the contributions of the Blood Dog Gang over the years.
He first used the beast skin of the Elephant-footed One to refine a robe, then the Ze Sand creatures, and finally carefully placed the Eerie Fetus.
This time the process was indeed steadier.
But after waiting two full days, it still ended in failure.
However, it did not explode; rather, the magical tool collapsed and was destroyed.
"Could it be that the Eerie Fetus Refining Method also has a time limit?"
"Impossible..."
Ren Qing slapped his head, suddenly realizing, muttering to himself: "The magical tool and the Eerie Fetus, aren't they just like the cultivator and the Supernatural Remnant..."
His eyes bloodshot, he once again refined a magical tool.
The material was still the beast skin of the Elephant-footed One, but the Supernatural Remnant was replaced with the Eerie Fetus of the Elephant-footed One at the Martial Practitioner Realm, simulating the process of ghost-devouring cultivation.
After spending several hours, the Tombstone Furnace went silent.
Ren Qing held an ordinary-looking gray robe in his hands, its texture like elephant hide. When he pulled hard, he found it much tougher than before.
But when he put it on, his expression revealed joy.
At first, Ren Qing could not use the magical tool, but after transforming into the Ghost Wolf, he felt the techniques and the Eerie Fetus Tool become connected.
The robe turned into a thick layer of elephant hide, protecting his whole body.
This Eerie Fetus Tool counted as having been made.
Ren Qing had already figured out the Eerie Fetus Refining Method.
First, for the Eerie Fetus to merge into the magical tool, it required a step-by-step ladder.
Just like how cultivators devoured Supernatural Remnants to advance, one must go from Martial Practitioner Realm Eerie Fetus, to Half-Corpse Realm Eerie Fetus, then to Ghost Envoy Realm Eerie Fetus...
The magical tools refined from Elephant-footed One materials could only merge with Eerie Fetuses of the same aberration path; otherwise, the refining would fail utterly.
The key of the Eerie Fetus Tool was not the Eerie Fetus, but the original magical tool itself.
Simply put, if Ren Qing refined the original magical tool using the materials of a Ghost Envoy Realm Elephant-footed One, then its upper limit would be the Ghost Envoy Realm.
Of course, this was on the premise that the Eerie Fetus successfully fused.
The success rate of fusion mainly depended on the strength of the consciousness born within the magical tool. As for this point, Ren Qing had not found any particularly good method.
But it had to be said, the potential of the Eerie Fetus Refining Method was absolutely terrifying.
Ren Qing felt it almost unbelievable that a method capable of changing the development of the Restraint Officers' Hall was now right before him.
He forcefully suppressed distracting thoughts and continued refining, letting the sandboat sail across the vast desert, no longer paying attention to outside matters.
When Ren Qing came back to himself, the Supernatural Remnants within the Prison Within the Abdomen were already used up, leaving behind only three finished magical tools.
These were two robes and a bone longsword.
It was not that the failure rate of refining was too high; mainly Ren Qing wanted to test the upper limits of the magical tools, so he kept refining repeatedly.
The three Eerie Fetus Tools he refined were all at the Half-Corpse Realm. Even if the corresponding Ghost Envoy Realm Eerie Fetus was obtained, the magical tool's consciousness could not bear it.
It still required further improvement.
Ren Qing picked up the bone sword, and after cutting his palm to stain it with some blood, with a simple blood refinement, he was able to control it as if wielding a sword with his will.
The bone sword flew horizontally up and down, maintained within a hundred meters.
Ren Qing's usage was slightly unskilled, and the range was not large, mainly because the Supernatural Remnant that the bone sword belonged to was called "Bone-Birth Technique".
With only his Bone Armor Technique, he could just barely control the bone sword. Only a cultivator who had mastered the Bone-Birth Technique could unleash its full power.
This showed that for cultivators like Song Zongwu and the others at the Yin Runner Realm, the Eerie Fetus Tool was probably of little use, unless it was an Eerie Fetus Tool at the Yang God Realm.
Ren Qing had originally been worried that, if the Eerie Fetus Refining Method spread, would it lead to situations of killing people to refine magical tools.
But thinking carefully, just the fact of requiring original magical tools made from living beings meant that Eerie Fetus Magical Tools could never be mass-produced.
And the Supernatural Remnants of the Great Dream Arcane Path could practically be described as cheap. Who knew how many the Restraint Officers' Hall had stockpiled over these hundreds of years.
Even if some types of Supernatural Remnants were missing, it was only because the cultivation conditions of those techniques were too harsh and had long since been cut off.
Ren Qing stroked the sandboat's wall with his hand and said: "Let's name you the Ghost Ship."
"Since techniques can form magical tools, Eerie Fetus Tools are bound to be mediocre, but if used to refine large-scale magical tools..."
One must know that the Ghost Ship's main material was not Bonewood, but the ribs of the Ksitigarbha, which was Yang God Realm material...
That meant the Ghost Ship's upper limit was the Yang God Realm!
Not to mention the Ghost Ship's consciousness was extremely unique. Even if sandboats filled the land in the future, his would still stand apart.
However, the Ghost Ship could only merge with Eerie Fetuses along the path of the Taotie Method's Secondary Stomach.
Ren Qing laughed loudly, his voice echoing through the cabin: "Reasonably speaking, every person having a Mustard-Seed Space is true orthodox cultivation."
As long as he spread the Taotie Method, through cultivators naturally dying and accumulating Supernatural Remnants, Yang God Realm Eerie Fetus Tools could sooner or later be refined.
Even though the consciousness of Eerie Fetus Tools was difficult to grow, there was always the possibility of success.
"We Restraint Officers, born as maggots on corpses, if we don't eat the corpse clean, what kind of maggots are we?"
