However, Yao Lao's face was still somewhat tense at this moment, and he said softly:
"Although this yin yang bone regeneration pill is only at the level of a Ninth-Grade Treasure Pill..."
"It is still categorized as a Ninth Grade Pill!"
"The medicinal ingredients required for its refinement are extremely difficult to find..."
"Furthermore, the unique aspect of Ninth Grade Pill is that it needs to contain the energy of Heaven And Earth, which requires the Alchemist's Soul Power to reach the Heaven Realm!"
"Moreover, only Late Heaven Realm Soul Power can mobilize enough Heaven And Earth energy to integrate into the Medicinal Pill..."
"There are very few people on this continent with Late Heaven Realm Soul."
After Yao Lao finished speaking, a hint of regret appeared on his face.
Although Yao Lao had successfully Rebirth and reached the Dou Sheng level at this moment, he had only just regained his Physical Body, and his aura was unstable!
His Soul Power had not completely recovered; currently, Yao Lao's Soul Power was only at the Peak of Early Heaven Realm, approaching the Middle Stage Heaven Realm level...
Relying on Yao Lao alone, he would be unable to refine a Ninth Grade Pill.
When Xiao Yi heard this, he also spoke softly:
"Yao Lao, you don't need to worry about the medicinal ingredients..."
"No matter what ingredients are needed, this junior will definitely find them, as this is the only hope for resurrecting the ancestor..."
"As for the Late Heaven Realm Soul, this junior will definitely hasten his Cultivation!"
"Once I achieve it quickly, I hope Yao Lao can refine the pill together with me at that time!"
After Xiao Yi finished speaking, he took out the sphere of Soul Origin he had obtained from the Human Hall...
The moment Yao Lao saw this sphere of light, he immediately understood what it was!
"The Hall of Souls is truly extremely cruel, possessing millions of Soul Origin like this!"
Yao Lao murmured softly, then raised his head to look at Xiao Yi and spoke again:
"You are already at Early Heaven Realm now. If you can refine this Soul Origin, you should be able to reach Late Heaven Realm!"
"In this way, by combining the strength of the two of us, refining the Ninth-Grade Treasure Pill should not be a problem..."
Xiao Xuan, who was standing nearby, did not speak at this moment, but merely nodded with great satisfaction as he looked at the much more mature Xiao Yi.
But Yao Lao paused and continued:
"However, right now, refining this yin yang bone regeneration pill still requires one crucial item..."
Xiao Yi: "May I ask what item that is?"
Yao Lao: "Heavenly Flame!"
Upon hearing the words Heavenly Flame, the Fallen Heart Flame and Sea Heart Flame immediately appeared in Xiao Yi's palm, and the Green Lotus Core Flame also emerged in Xiao Yan's palm!
Coupled with Yao Lao's Bone Chilling Flame!
Since they already possessed four types of Heavenly Flame at this moment, Xiao Yi was still puzzled why Yao Lao said they lacked a Heavenly Flame...
"Yao Lao, if four types of Heavenly Flame are still not enough..."
"As far as I know, the Pill Tower still possesses the Three Thousand Burning Flame..."
Before Xiao Yi could finish speaking, Yao Lao raised his hand and interrupted him:
"It's not that the number of Heavenly Flame is insufficient..."
"Rather, we lack one crucial Heavenly Flame that is absolutely necessary..."
"That is the Yin Yang Twin Flames, ranked twenty-first!"
"The reason the yin yang bone regeneration pill can bring the dead back to life and make flesh grow on white bones is that the Yang Fire power of the Yin Yang Twin Flames is the key!"
"Although the Yin Yang Twin Flames is only ranked twenty-first, it is still a Heavenly Flame, and we both know how difficult Heavenly Flame are to find..."
"Therefore, the most urgent task is to first find the Yin Yang Twin Flames..."
However, as soon as Yao Lao finished speaking, Xiao Yi's previously tense expression instantly relaxed!
Xiao Yi had thought the issue was the insufficient number of Heavenly Flame, but he didn't expect it to be a specific Heavenly Flame, the Yin Yang Twin Flames... He actually possessed this item!
"To be honest, I already found the Yin Yang Twin Flames in the Sound Valley. My original intention was to subdue that Heavenly Flame to resolve Xiao Yi Xian's Calamity Poison Body, but unexpectedly, it has now also become a great aid in resurrecting the ancestor!"
"Fate truly works in mysterious ways..."
Xiao Yi's lips curled up slightly. Looking at this, resurrecting Xiao Xuan was now a certainty...
Yao Lao's expression was completely different from Xiao Yi's; Yao Lao was filled with shock:
"Are you saying that the Yin Yang Twin Flames has already been absorbed by Xiao Yi Xian?"
Xiao Yi nodded.
Receiving the affirmative answer, Yao Lao was deeply shocked!
After all, in Yao Lao's understanding, Heavenly Flame were extremely rare treasures that countless Alchemist sought for their entire lives without success!
He himself had barely survived when trying to obtain the Bone Chilling Flame, and his master, Han Shanshan, had even perished because of it—this was the pain of Yao Lao's life...
Yet, such a Heavenly Flame seemed so easily obtainable in front of Xiao Yi...
Yao Lao was truly shocked in his heart...
But Yao Lao quickly calmed down. After all, Xiao Yi had a figure like Xiao Xuan behind him, someone capable of manipulating everything...
Everything unreasonable involving him instantly became reasonable.
Now that the matter of refining the Medicinal Pill was resolved, Yao Lao spoke softly again:
"The Medicinal Pill issue can temporarily be resolved..."
"However, for an extraordinarily powerful Soul like Senior Xiao Xuan's, finding a Physical Body capable of accommodating him will likely be difficult!"
"Furthermore, if we want Senior Xiao Xuan's strength to remain undiminished after his Rebirth, we also need to find some Heaven And Earth Treasure to restore Senior Xiao Xuan's Soul Origin power..."
Yao Lao's thoughts were extremely meticulous, considering everything thoroughly.
Xiao Yi was the same; he took out the remains of the Half-Emperor expert Heavenly Cold Demon Saint, along with the Soul Origin of Soul Mie Sheng, the Hall Master of the Soul Hall, and presented them together...
"The body for the ancestor's Rebirth has naturally been prepared long ago..."
"The ancestor was a Half-Emperor expert during his lifetime, so naturally, only the body of another Half-Emperor expert can contain his Soul..."
"As for the Soul Origin power, if the ancestor absorbs this Heavenly Realm Great Perfection Soul Origin of Soul Mie Sheng, he should be able to recover to his Peak strength..."
Looking at the two great treasures before them, both Yao Lao and Xiao Yan felt as if everything was illusory!
A Half-Emperor's body, the Soul Origin of Soul Mie Sheng... all of this was simply too unbelievable...
Yao Lao was even stuttering at this moment:
"Th-th-then..."
"Now, only the medicinal ingredients are missing..."
Xiao Yi: "Medicinal ingredients, please tell me directly, Yao Lao..."
"No matter what medicinal ingredients are needed, this junior will definitely find them at the fastest speed!"
Yao Lao nodded:
"The most crucial item is the yin yang marrow heart. This item grows in the fissure where the land of extreme Yin and the abyss of extreme Yang converge, and like the Yin Yang Twin Flames, it contains pure Yin and Yang Origin power..."
"Besides the yin yang marrow heart, we also need the Dragon Tendon of the Eighth-rank Magical Beast Nine Nether Cold Dragon, the nine yang fire ganoderma that grows in the unextinguished fire eye of a volcano, and the Ten Thousand Year Rotting Bone Rebirth Grass..."
"These ingredients are all top-grade treasures; it can be said that the rarity of each one is no less than that of a Heavenly Flame!"
"It will likely be difficult to gather them all within a short period of time..."
After Xiao Yi heard this, he had already firmly committed all these ingredients to memory:
"Ancestor, please rest assured..."
"Even if these ingredients are difficult to find, I will definitely gather them all!"
"The day of your Rebirth must not be far away!"
After Xiao Xuan heard this, he looked at Xiao Yi's determined gaze. Although Xiao Xuan did not speak, he simply nodded.
But from Xiao Xuan's gentle eyes and smile, it was clear that he chose to unconditionally trust the young man who had grown up along this path...
