The jade pendant soaked in Fire Phoenix Blood did not change color at all.
Not even the slightest change or movement.
"It really doesn't work..."
Lin Yue sighed helplessly and shook his head slightly, slowly pouring the Fire Phoenix Blood back into the Glazed Box. The Glazed Box then generated an invisible suction, absorbing all the Fire Phoenix Blood.
He wondered whether it required the so-called 'Essence Blood' or if it had to be the Essence Blood of a 'cultivator.'
The situation was clear.
Fire Phoenix Blood indeed could not be used for a blood sacrifice. It seemed that only after the blood sacrifice was completed and the Blood Jade of All Souls was stimulated could the Fire Phoenix Blood be used as a bloodline for fusion and refinement, making it a part of oneself.
Once Lin Yue quietly stored the Fire Phoenix Blood again, he returned to the cave mansion to continue pondering what to do.
Failure was expected, and he was not disheartened.
If he didn't have this bit of patience, he might have already collapsed during these three months of torment.
He sat down again at the stone table in the cave mansion.
"Now it seems the biggest challenge is the first step of the blood sacrifice."
Lin Yue slowly furrowed his brows, "It probably requires nine cultivators who have broken through the Five Elements Heavenly Barrier to sacrifice half their Essence Blood, or one cultivator who has broken through the Four Symbols Heaven Barrier to sacrifice half their Essence Blood."
For the Demon Path figure who refined this Blood Jade of All Souls, perhaps it truly was not difficult, which is why it was called a 'simple blood sacrifice.'
Even for the owner of this cave mansion, this condition might not be hard to achieve.
But for Lin Yue, the difficulty was beyond imagination.
"Five Elements Heavenly Barrier? Four Symbols Heaven Barrier?"
Lin Yue sighed.
These days, he had gone through many Daoist texts.
He had a little understanding of the so-called 'Heavenly Barriers.'
They were barriers set by the heavens for all souls in the world.
Mortals found it extremely difficult to perceive the Essence of Heaven and Earth, and even if they introduced energy into their body, it was only a tiny trace of the Essence of Heaven and Earth. They could never transform the mortal body.
This was because of the first Heavenly Barrier, the Five Elements Heavenly Barrier.
Only when one's spirit, physical body, perception, and other aspects were enough to break through the Five Elements Heavenly Barrier, could they harness the Five Elements Essence for cultivation, truly stepping into the realm of cultivators and beginning the path to transcendence.
For example—
A Martial Cultivator who reaches the peak by fully developing the mortal body and refining energy to a micro level of perfect unity, might with external force or a secret technique, break through the Five Elements Heavenly Barrier to become a true Martial Arts cultivator.
People of the Three Religions also needed to meet certain conditions to break through the Five Elements Heavenly Barrier.
Even Imperial Family members like the Xiahong clan, if they do not break through the Heavenly Barrier, cannot transcend!
Any cultivator who broke through the Five Elements Heavenly Barrier was a truly significant figure to mortals.
For instance, a Martial Cultivator could become a commander of ten thousand troops at the Northwest Border.
Even the Capital Commandant overseeing thousands of the City Guard Army in Qingdu was not as powerful as a Martial Cultivator, and a Martial Cultivator would not stoop to being in small Qingdu.
And yet the first step of the blood sacrifice required nine such formidable individuals to offer half of their Essence Blood?
It was utterly preposterous.
"There are fifteen commanders at the Heroic Pass in the Northwest, which means fifteen Martial Cultivators who have broken through the Five Elements Heavenly Barrier."
Lin Yue tried to expand his thoughts, "If I disguise myself as Baili Fengzhi and go to the Northwest Pass, perhaps I could get the Essence Blood of nine of them?"
But he immediately shook his head slightly, rejecting his own thought, "It's too far-fetched."
This method was too difficult to realize.
Even if there were a resemblance, to become Baili Fengzhi, he would first need to acquire a part of her body, like some hair strands with follicles.
Perhaps he could become one of Baili Fengzhi's maidservants or servants to approach her, but for such a Martial Arts master, whose control over her own body was nearly perfect, how could she not notice her hair was being pulled?
Even if it truly succeeded, he would then need to travel to the Northwest Pass.
He didn't even know where the Northwest Pass was, let alone that Baili Fengzhi had come with her Personal Guard, and if he entered the Northwest Pass alone without a Personal Guard following, it would already be very suspicious.
Moreover, those commanders were also Martial Cultivators, military officers of quite high rank in Great Yong. Subordinates, not slaves, why would they casually sacrifice half their Essence Blood?
And the other option was even more absurd.
To have one cultivator who had broken through the Four Symbols Heaven Barrier sacrifice half of their Essence Blood?
A warrior who could break through the Four Symbols Heaven Barrier was considered a significant figure even among cultivators.
Lin Yue didn't even need to think.
That commander of the border army at the Northwest Pass, Baili Fengzhi, her secret was at the Third Ring Level, higher than ordinary Martial Cultivators and advanced cultivators.
Following this speculation, she was very likely someone who had broken through the Four Symbols Heaven Barrier!
"Use Baili Fengzhi's secret to coerce her into handing over half of her Essence Blood?"
A thought flashed through Lin Yue's mind, but he immediately abandoned this suicidal idea.
Not to mention that his request for half the Essence Blood would be suspicious, what would a mere mortal want with the Essence Blood of such a Martial Arts master like Baili Fengzhi?
Not to mention, he didn't have the qualifications to threaten Baili Fengzhi. Dare to make such a request, and he might be slapped to pieces.
Old Daoist Tu was also likely a Daoist master who broke through the Four Symbols Heaven Barrier, but Old Daoist Tu was currently being imprisoned by Baili Fengzhi.
Even if there was a chance, he could not possibly ask Old Daoist Tu for half of his Essence Blood.
He knew Old Daoist Tu didn't have many years left because of certain reasons, and if he gave up half of his Essence Blood, he would likely die on the spot.
