Ren Qing only after sailing a hundred li away did he begin to check the Butterfly Dream Technique in his mind.
He discovered that the Butterfly Dream Technique was far more profound and mysterious than imagined, as if it was a cultivation method created by a cultivator in a half-dream, half-awake state.
Although Ren Qing had not come into contact with the actual manual of the Butterfly Dream Technique, since he knew its contents, the information stream quickly appeared.
[Butterfly Dream Technique]
[Comprehended in a dream by the Great Dream True Person, cultivating it requires thirty days without sleep, and visualizing the nightmare demon within the dream, only by not dying can it be completed.]
Ren Qing did not expect that the Butterfly Dream Technique was actually related to the Great Dream True Person.
Although it was not necessarily created by him, but more likely accidentally cultivated by chance, this also illustrated the terrifying talent of the Great Dream True Person.
The conditions for cultivation seemed sparse and ordinary at first glance, but in truth they were even more difficult than imagined.
[If after thirty days it is still not completed, the soul will fall into the nightmare demon's dreamscape, and the body and soul will undergo uncontrollable aberration.]
Ren Qing suspected that the reason the Great Dream True Person presented himself as distorted light and shadow might very well be because of aberration out of control when he first cultivated the method.
He couldn't help but suck in a cold breath.
Frankly speaking, Ren Qing could only rely on the Prison Within the Abdomen to temporarily harness the aberration of the Supernatural Remnant, while the Great Dream True Person maintained such a state at every moment.
No wonder it always felt as if the Great Dream True Person was half-awake and half-asleep, rarely responding.
Ren Qing continued to examine the information.
[Butterfly Dreamer: Soul like dreamscape]
[Dream Butterfly: Soul roams in dreams]
[Dreamless: Dreamless and sleepless]
The Great Dream True Person had many annotations on the Butterfly Dreamer and the Dream Butterfly.
But regarding the Dreamless, he did not mention it, presumably he himself did not know about this aberration route.
The Butterfly Dreamer could have the soul depart from the body during sleep, thereby constructing a dreamscape.
At the Ghost Envoy realm "Great Dream Awakens," the cultivator's control over the dreamscape would increase greatly, and the display of all kinds of illusions would be effortless.
The Dream Butterfly and Butterfly Dreamer seemed not very different, both constructing dreamscapes with the soul, but after reaching the Half-Corpse realm they were worlds apart.
The Dream Butterfly upon promotion was called "An Inch of Time."
As long as the target was within the dreamscape, the soul butterfly could attach itself to their body.
The soul butterfly was also considered a type of magical implement, similar to the Dream Seed.
After attachment, the soul butterfly could steal lifespan, but the prerequisite was that the other party must not resist in their heart, and moreover it was only a few minutes of lifespan, so one inevitably had to use the method of exchange.
The Great Dream True Person walked the path of the Dream Butterfly, and he had also revealed the method of cultivation.
It required thirty days without sleep, achieving separation of body and soul, letting the body fall into slumber while the soul continued visualizing the nightmare demon.
Then one could complete becoming a "Dream Butterfly."
When "An Inch of Time" advanced to the Yin Runner realm's "Three Inches of the Human World," one could transform the soul butterfly magical implement into a large-scale dreamscape like the Ghost Market.
The stolen lifespan would also become more.
At the Yang God realm was "Ruler of the Dream Kingdom." The Great Dream True Person did not describe much of this, but just by looking at the phantom of Grand Duke Taisui in midair above Avici Hell, one could know its power.
The Great Dream True Person might well be able to rely on Grand Duke Taisui to advance to the Heavenly Abomination realm.
As for the Dreamless, Ren Qing felt the ability was more like protection against dream-type techniques, using dreamlessness and sleeplessness to weaken the illusions generated by dreamscapes.
If Ren Qing had not seen An Inch of Time, he might really have chosen the Dreamless.
After all, only by stacking defense could one achieve being unmatched in the same realm, but since it involved prolonging life, there was no need to consider further.
The sand ship continued sailing swiftly, but Ren Qing deliberately slowed the speed, making the cabin gradually stabilize.
He then closed his eyes.
[Can consume thirty days of lifespan, exempting the cost of mastery]
Ren Qing instantly fell asleep, his consciousness immersed in boundless darkness, faintly able to hear hair-raising strange laughter.
Before long, something condensed into form within the darkness, slowly crawling closer.
Blood-red eyes opened, their gaze filled with ferocity.
The mouth on the lower jaw bore sharp teeth, faintly appearing as a half-bodied eerie creature, very much like the nightmare demon of rumor.
Before the nightmare demon could affect Ren Qing, Ren Qing's aura suddenly boiled.
Crack crack crack crack...
The Lord of Absolute Darkness, as if provoked, transformed into gray-black smoke forming ferocious visages, directly shattering the aberration that arose during grasping of the technique.
Ren Qing opened his eyes; the whites of his eyes became minimal, replaced by countless stacked Double Pupils.
But after only a moment it returned to normal, and the rampaging Supernatural Remnant calmed down.
Ren Qing attempted to perform the Butterfly Dream Technique, and specks of fluorescence appeared at his fingertips. Perhaps because he was only at the Martial Practitioner realm, the effect was unremarkable.
His consciousness entered his mind to examine the aberration tree of the Butterfly Dream Technique.
[Do you wish to choose the Dream Butterfly branch, it will consume one year of lifespan]
Ren Qing once again fell asleep.
He seemed to transform into a butterfly just breaking its cocoon, shuttling among the forest, experiencing the entirety of a butterfly's life in only a few breaths.
When the advancement succeeded, a lifelike butterfly appeared in Ren Qing's palm.
The wings of the soul butterfly opened and closed, even giving off faint air fluctuations, impossible to distinguish as real or false with the naked eye.
What most surprised Ren Qing was that the three Dream Seeds seemed to connect with the soul butterfly, showing how high the compatibility of these two techniques was.
He even suspected that when promoted to Merging the Yin God, the two techniques would generate a primary-secondary relation, and the magical implements might transform.
"Worthy indeed of the Butterfly Dream Technique…"
Ren Qing's thought moved.
The cabin turned into a lush forest; unless one checked the details of the grass and soil, it was impossible to discern reality.
As long as someone believed the illusion, Ren Qing could easily draw them into sleep.
It complemented exactly the abilities of the Double Pupils of The Blindless Method.
Ren Qing looked at the lifespan barely over ten years, and sent a large number of eyeballs into the Flesh Furnace, stabilizing and increasing lifespan.
He had the ghost shadow refine a magical implement modeled after the sand ship; the materials had backups prepared earlier, so there was no need to go to Avici Hell again.
Moreover, the Ghost Market was still closed.
The ghost shadow skillfully refined the planks, requiring no control from Ren Qing.
Only the dragon bones were troublesome; he had to break apart the ribs of Ksitigarbha to refine, which somewhat affected the quality.
But if the Restraint Officers' Hall only used it for transportation, it was more than enough.
Ren Qing rested for a moment then continued secluded cultivation, attempting visualization of The Blindless Method, discovering that the progress of the Butterfly Dream Technique also slightly advanced.
He spent several days stabilizing his realm before sending his consciousness back into the Niwan Palace.
[Do you wish to choose the An Inch of Time branch, it will consume ten years of lifespan]
The aura of the Ghost Envoy realm flickered briefly, as soul butterflies fluttered around Ren Qing, their forms becoming increasingly dreamlike.
Then the soul butterfly split into two, two into four...
Before long, the cabin was full of soul butterflies, even passing through the walls into the storage room next door.
At that moment, Ren Qing reached out to grasp one of the soul butterflies in the cabin; as light and shadow shifted, the other butterflies disappeared at once.
After advancing to An Inch of Time, the soul butterfly magical implement could divide into hundreds, and could obtain lifespan from multiple Restraint Officers simultaneously.
Though each time was only a few minutes, it was far more than what the Great Dream forge could gain.
But Ren Qing had just been in seclusion for only a few days, and for the Butterfly Dream Technique to suddenly advance to the Ghost Envoy realm was unreasonable, so he would go to the Ghost Market after some time.
After mastering An Inch of Time, both the primary and secondary souls had changed, with a layer of flickering hazy light around the surface of his body.
Ren Qing then focused on refining magical implements, mainly to explore a method of using Supernatural Remnants for refining.
Even Supernatural Remnants at the Martial Practitioner realm had recovery far exceeding imagination after injury, perfectly suited for trying refining.
Ren Qing's methods were extremely rough, completely disregarding reasonableness, only using the Restraint Officer Method and the Heavenly Dao Method to blaze a new trail of refining.
For him, as long as he could complete a rudimentary refining method it was enough.
Once some Restraint Officers mastered it, naturally talented cultivators would innovate further, forming a system within decades.
So Ren Qing no longer thought too much, selecting over a dozen refining methods that seemed most promising, and testing them one by one.
Things like corpse burial, coffin sealing, gestation, blood refining…
Ren Qing went to the prison corridor, dragged a human-faced tiger to an open space.
Then he pried open its mouth with force, ignoring its frenzied struggles, and poured liquefied molten iron straight into it.
The Prison Within the Abdomen resounded with the screams of the Supernatural Remnant, making one's hair stand on end.
Moments later, a hole appeared in the belly of the human-faced tiger, and a solidified iron block fell out.
It became weak and dying, yet still struggled to resist, then was tossed by Ren Qing into the Flesh Furnace.
"Supernatural Remnants count as flesh and blood creatures, hard to merge with materials…"
Ren Qing pinched his nose bridge in frustration, and continued to try the next refining method.
But Supernatural Remnants were extremely special; even those at the Martial Practitioner realm had intelligence comparable to children, not to mention Half-Corpse and Ghost Envoy realms.
He grabbed a Half-Corpse realm Supernatural Remnant, put it into blood mixed with various materials, and simmered it for more than seven days.
The result was the Supernatural Remnant broke free not long after, becoming lively again.
Ren Qing tried all the refining methods he could think of, but without exception.
Even burning most of the Supernatural Remnant with fire did not show any trend of refining into a magical implement, making him disappointed.
"Could it really be impossible...."
Ren Qing narrowed his eyes. If he could completely erase the consciousness of the Supernatural Remnant, perhaps it would greatly help refining progress.
He picked up a Martial Practitioner realm Supernatural Remnant and went to the outside world.
Ren Qing stepped out of the cabin and stood on the deck, binding the Supernatural Remnant with Dragon-Snake Spine, then threw it straight into the endless sand sea.
The Supernatural Remnant frantically struggled to break free, but the Dragon-Snake Spine grew tighter and tighter.
In just a few breaths, Ren Qing felt its movements weakening.
He quickly retrieved the Dragon-Snake Spine; the once ferocious Supernatural Remnant was gone, leaving only a fist-sized lump of flesh.
He picked up the lump, which felt like a lifeless dead thing.
The information stream emerged.
[Eerie Fetus]
[Formed when a Supernatural Remnant dies in the womb, consuming it leads to body and soul aberration, and if not processed, in a short time will turn to ash.]
Ren Qing's mouth fell slightly open, he seemed to have inadvertently created something remarkable.
This might very well change the entire situation of the Restraint Officers' Hall.
The sand ship seemed to sense the existence of the eerie fetus, its dragon bones twisting continuously, as if eager to absorb it.
The sailing speed became unstable, nearly crashing into a giant sand dune.
Ren Qing put away the eerie fetus, muttering: "This thing can let a magical implement undergo transformation?"
"Then since it is my own magical implement, I must pick a better Supernatural Remnant..."
