The tabletop was covered with a dazzling array of various tools.
Hua Yanyun picked up a set of silver needle-shaped artifacts refined from Void Refinement-grade heavenly treasures.
The silver needles rested in Hua Yanyun’s hand, their tips glinting with cold light.
Though they looked ordinary, they were genuine Void Refinement treasures, incredibly rare and precious.
“This item is called the Origin Suppressing Needle. There are forty-eight needles in a complete set, and they are extremely precious.”
“As the name suggests, these needles possess the miraculous ability to seal a cultivator’s immortal yuan and release it in an instant. They can also serve as a precise medium for transmitting spiritual power.”
As if suddenly intrigued—or perhaps simply out of a cruel desire to make He Shu even more terrified—Hua Yanyun introduced the silver needles while steadily driving them into the critical nodes of He Shu’s spiritual veins.
The importance of spiritual veins to a cultivator needed no explanation.
The needles sank deep inside, sending pain like ten thousand arrows piercing the heart.
“Aaaaahhhhhh!”
The agony made He Shu’s eyes roll back.
She wanted to scream, but her body lay completely motionless on the bed, utterly at Hua Yanyun’s mercy.
All she could do was wail madly inside her mind.
Hua Yanyun did not use all the needles.
She only took half the set.
From a distance, it looked as if she were simply performing acupuncture on the girl lying on the bed.
But only He Shu, the one experiencing it firsthand, knew this was no acupuncture at all. It was pure, unadulterated torture.
Once all twenty-four silver needles had been inserted into her body, Hua Yanyun condensed a ball of her own immortal yuan in her palm.
Nascent Soul cultivators produced true yuan within their spiritual veins.
However, once a cultivator reached the Body Integration realm, survived the immortal tribulation, and shed their mortal form to become an immortal, their spiritual veins would evolve into immortal veins, compressing their true yuan into immortal yuan.
Immortal yuan was fundamentally different from true yuan.
He Shu had only been at the mid-Nascent Soul stage before; her spiritual veins had never undergone immortal tribulation and could barely withstand the impact of immortal yuan.
As Hua Yanyun poured more and more immortal yuan into He Shu’s spiritual veins, He Shu’s body began showing signs that it could no longer endure.
Yet just before her spiritual veins were about to collapse completely under the foreign power, Hua Yanyun stopped the infusion at the perfect moment.
Tearing pain spread through her four limbs and hundreds of bones.
The pressure from the immortal yuan on her spiritual veins was simply too strong—especially with Hua Yanyun’s divine sense still roaming freely inside her body.
After carefully probing, Hua Yanyun discovered a strange power deeply rooted within He Shu’s body.
This power was hidden extremely well inside her. Hua Yanyun had used her divine sense to examine He Shu’s body more than once before, yet she had never detected even the slightest trace.
Curious, Hua Yanyun began a detailed study of this force.
It appeared to be some kind of imprint, and it had already completely fused with He Shu’s body, becoming inseparable from her.
“What a grand gesture. This is actually a Body Integration-level imprint technique. How many resources must have been consumed to refine it, and how many attempts did it take to succeed?”
Imprints were a type of artifact, usually given by elders to juniors for life protection.
They needed to be planted inside the cultivator’s body.
Normally, an imprint could be removed from the body, but the one inside He Shu had truly become one with her.
“The imprint was probably planted in He Wanyi by that old woman He Xiu herself. Perhaps even she didn’t expect the little one’s constitution to be so special that once the imprint was planted, it could never be taken out again.”
Hua Yanyun quickly calculated in her mind and felt this possibility was quite likely.
After all, the Mystic Soul Pure Sound Physique was far too unique.
“Unless something unexpected happens, He Wanyi should be the highest-ranking Southwind spy within the Jade Water Immortal Kingdom. Hehehe, now that We have caught her red-handed, I wonder what kind of amusing expression that old woman He Xiu will have when she first learns of it.”
Thinking of He Xiu suffering a setback, Hua Yanyun’s mood improved considerably.
Hua Yanyun withdrew her divine sense but did not withdraw the immortal yuan from He Shu’s body.
She was deliberately leaving it there. She wanted to test He Shu’s extraordinary recovery ability.
As long as the immortal yuan remained inside He Shu, it would continue to damage her spiritual veins.
The pain that felt like her body was being torn apart lasted a full hour before Hua Yanyun finally removed one Origin Suppressing Needle from the area over He Shu’s heart.
Like opening the floodgates of a dam, as the rampaging immortal yuan was slowly drained out bit by bit, He Shu felt an overwhelming sense of relief wash over her body.
“The recovery ability of an Absolute Physique is truly beyond imagination.”
Hua Yanyun clicked her tongue. After examining He Shu’s spiritual veins, she couldn’t help but sigh in admiration.
In that one hour, He Shu’s spiritual veins had only suffered minor damage and were already slowly healing themselves.
Hua Yanyun knew full well how devastating immortal yuan was to ordinary spiritual veins.
If He Shu had been a normal cultivator below the Body Integration realm, her spiritual veins would have been riddled with holes and would have needed at least a hundred years to recover.
This was not surprising.
The reason Absolute Physiques defied common sense was because they were essentially a special kind of quasi-immortal vein, already possessing a certain degree of compatibility with immortal yuan.
Hua Yanyun’s desire to explore He Shu’s Mystic Soul Pure Sound Physique grew even stronger.
“Why not be a little more aggressive?”
After all, it wasn’t her who would be in pain. Hua Yanyun took out the remaining twenty-four Origin Suppressing Needles.
The silver needles floated in the air about a foot above He Shu.
Under her precise control, they accurately pierced different points along He Shu’s spiritual veins.
Hua Yanyun cast a spell, using the Origin Suppressing Needles to stimulate He Shu’s spiritual veins through intermittent releases of spiritual power fluctuations.
She was trying to draw out even deeper potential from the Mystic Soul Pure Sound Physique.
A powerful electric current instantly spread throughout her entire body.
Even though He Shu was completely paralyzed, her body instinctively convulsed.
Thanks to the restraints on her limbs, she did not fall off the experimental table.
After this stimulation, Hua Yanyun immediately noticed that He Shu’s spiritual vein recovery speed had increased several times over.
She tried extracting a wisp of He Shu’s spiritual vein origin.
To her astonishment, she discovered that the missing origin was slowly regenerating!
“Could the only characteristics of the Mystic Soul Pure Sound Physique be rapid self-healing and regeneration?”
Hua Yanyun pondered. Her intuition told her that things were far from that simple.
According to the records in Cha Yuan’s biography, his close friend had once revealed that the Mystic Soul Pure Sound Physique was immune to soul path techniques.
Hua Yanyun had personally verified this.
That was why she had not researched the soul-related aspects of He Shu’s body too deeply.
Yet she had unexpectedly discovered this monstrous self-healing ability.
It was a universally acknowledged iron law in the cultivation world that damaged origin could not regenerate.
Yet He Shu—or rather, the Mystic Soul Pure Sound Physique—had broken this iron law.
Hua Yanyun was extremely excited by this discovery.
She did not believe this was a privilege exclusive to one special physique, but with only He Shu as her sole specimen, it was difficult to verify.
This torture, disguised as an experiment, lasted for several hours.
During this time, He Shu truly understood what it meant to be better off dead.
It was simply too terrifying.
Toward the end, Hua Yanyun even used the array to simulate a small-scale heavenly tribulation, nearly striking her to death.
