"Yue Guan and Gui Mei were somewhat speechless from shock."
"As veterans, they knew all too well how precious the thing inside this Fallen Spirit Master's Dantian was."
"After examining the actual situation, Yue Guan remembered that Yu Xiaogang had only come over to inspect this after seeing the Fallen Spirit Master's notes."
"Therefore, he turned his head to look at the notes in Yu Xiaogang's hands."
"'Xiaogang, does that record how this thing is formed?'"
"As soon as the words fell, Gui Mei's gaze turned to Yu Xiaogang's hands."
"'Yes, it does record how it's formed, but the reason it was able to possess this is entirely because of its Spirit.'"
"Yu Xiaogang handed the notes to Yue Guan, and Yue Guan and Gui Mei immediately opened them and began reading word for word."
"At the same time, Yu Xiaogang once again inspected the situation inside the Fallen Spirit Master's Dantian."
"The rotating Soul Power Vortex, and the structure that was gradually transforming into a solid, eventually forming a Soul Pill."
"While the Soul Power Vortex rotated, the aura emanating from within it allowed Yu Xiaogang to easily perceive that this was the same aura the Fallen Spirit Master had leaked when preparing for battle earlier."
"It was an aura identical to the Fallen Spirit Master's Spirit."
"Through observing this Soul Power Vortex, it was as if Yu Xiaogang was observing a miniature Spirit Master."
"Feeling the fluctuations of the Soul Power Vortex, Yu Xiaogang's fingers trembled slightly."
"Yue Guan and Gui Mei might only see the significance of this thing in actual combat."
"But Yu Xiaogang was different from them; he knew much more clearly."
"Perhaps there was no other Spirit Master in the world who understood the significance of this thing better than Yu Xiaogang."
"Back when Yu Xiaogang was theorizing about the power core of Spirit Beasts, his final hypothesis was that the Spirit Beast's power core was their Spirit Bone."
"Afterward, when obtaining his fifth spirit ring, Yu Xiaogang specifically went to meet Arou and the others to consult them on this question."
"At first, Arou and the others did not want to answer, but when Yu Xiaogang described his thought process in detail, Arou and the others were all shocked."
"Eventually, Yu Xiaogang received an answer."
"'That's right, the core of us Spirit Beasts is indeed our Spirit Bone.'"
"'When our strength is not yet strong, this core is just a mass of gaseous Soul Power. As our strength progresses, this gaseous Soul Power gradually solidifies, forming a mass of liquid Soul Power.'"
"'And when we reach one hundred thousand years, this liquid Soul Power will condense into a solid, forming a miniature core of our true body.'"
"'This core symbolizes our most core, most Origin power. After we die, this core will transform into a Spirit Bone.'"
"'Those skilled in strength transform into arm bones, those skilled in speed transform into leg bones, those with powerful comprehensive strength transform into torso bones, and those with powerful Mental Energy transform into skull bones.'"
"'This is the secret of Spirit Bones.'"
"Having received this answer which did not exceed his expectations, Yu Xiaogang nodded."
"'So, the reason a Hundred Thousand Year Soul Beast is guaranteed to drop a Spirit Bone upon death is because the Hundred Thousand Year Soul Beast's power core has already formed into a solid.'"
"'Then, to take it a step further,'"
"'When a Spirit Beast has already condensed a solid Soul Power core before reaching one hundred thousand years, does it mean that the Spirit Beast already possesses the potential to become a Hundred Thousand Year Soul Beast?'"
"'Or perhaps it's no longer just potential, but guaranteed to become a Hundred Thousand Year Soul Beast.'"
"'But such Spirit Beasts are destined to be rare; this is also the reason why Spirit Bones are rare.'"
"'Am I guessing correctly?'"
"As Yu Xiaogang's voice fell, the scene fell into silence. Arou and the others looked at Yu Xiaogang with expressions as if they were looking at a monster."
"A moment later, Arou sighed with heartfelt emotion."
"'I am completely convinced by you. In this era, if you don't become a god, I won't acknowledge whoever else becomes a god!'"
"'Hmm... or rather, with that brain of yours, even if you hadn't encountered a good era, you would still be able to take that final step relying on your own ability.'"
"There was helplessness in Arou's tone, but her words were full of praise."
"'You guessed correctly. Those Spirit Beasts that drop Spirit Bones before reaching one hundred thousand years actually represent that they already possess the qualifications to cross the threshold of one hundred thousand years.'"
"'As long as they can continue to Cultivate, they will definitely become Hundred Thousand Year Soul Beasts just like us!'"
"Hearing this, Yu Yuanzhen, who had been silently listening and digesting, raised a question."
"'But aren't Hundred Thousand Year Soul Beasts something that can be achieved just by living to that age?'"
"Hearing this question, Arou sighed."
"'Yes, living to one hundred thousand years is enough to become one.'"
"'But during these one hundred thousand years, we Spirit Beasts also hunt, consume rare treasures, and some with high intelligence even Cultivate before one hundred thousand years.'"
"'Some Spirit Beasts have only lived for two thousand years, but they possess the level of fifty thousand years.'"
"'Do you think for this type of Spirit Beast, they need to live for one hundred thousand years to become a Hundred Thousand Year Soul Beast?'"
"Speaking to this point, Arou looked at Yu Xiaogang."
"'For us Spirit Beasts, one hundred thousand years is actually a threshold.'"
"'Facing this threshold, most Spirit Beasts, as you said, live for one hundred thousand years. Once the age is reached, the Spirit Beast's power core will condense on its own, allowing it to cross the threshold.'"
"'But no one has ever known that even for the Spirit Beasts with the poorest Aptitude, when they live to seventy or eighty thousand years, their actual age should be at a point where they are only one step away from one hundred thousand years.'"
"'But this threshold blocks them, making it so they can only cross that threshold when they truly live to one hundred thousand years.'"
"'There are even a small number of Spirit Beasts with exceptional talent, just like you human Genius Spirit Masters.'"
"'Their strength increases rapidly, and at two or three thousand years, or even younger, their strength reaches before the threshold of one hundred thousand years.'"
"'At this time, if this Spirit Beast's Soul Power core has already condensed, then it can easily cross this threshold.'"
"'And if the core has not yet condensed, then it will be stuck by this threshold. If it can never condense it, then it can only live to one hundred thousand years, letting the power core condense on its own.'"
"'I suppose you can understand the difference between living to one hundred thousand years and possessing a power core before one hundred thousand years, then crossing the one hundred thousand year mark, right?'"
"Yu Yuanzhen did not speak, but he already understood in his heart."
"Isn't this just the difference between a normal Spirit Master and a Genius Spirit Master?"
"The only difference is that on the Spirit Beast side, there is a guaranteed mechanism; as long as they live, their strength can continuously rise."
"Yu Xiaogang, who was on the side, heard this and couldn't help but sigh that while the Cultivation systems of Spirit Beasts and humans have many similarities, they are indeed very different."
"After clarifying the hypothesis that the Spirit Bone is the Spirit Beast's power core, Yu Xiaogang thought of his subsequent ideas."
"Since Spirit Beasts can condense a power core that represents their own power, can human Spirit Masters also achieve something similar?"
"Even after learning about the significance of the Spirit Beast's power core to Spirit Beasts, Yu Xiaogang made a further conjecture."
"Known: If a Spirit Beast possesses a Soul Power core before one hundred thousand years, then they no longer have the threshold of breaking through one hundred thousand years; as long as the strength is reached, they can advance."
"Then, if it were a human Spirit Master, if they could also condense a power core belonging to human Spirit Masters, would that mean that when a human Spirit Master breaks through to a level equivalent to a Hundred Thousand Year Soul Beast, there would be no more obstacles?"
"To put it more bluntly, as long as a human Spirit Master can condense this power core, does it mean they are guaranteed to break through to Titled Douluo?"
