Hongyan Mavis shook her head. "None of us ever knew, as he never revealed it."
Lu Yin grew even more wary. He had completely forgotten that Ancient God also knew the Origin Sutra.
The Three Realms and Six Daos were all disciples of the Origin Progenitor, and all of them had learned the Origin Sutra.
The Origin Sutra was an all-inclusive cultivation method, much like Lu Yin’s inner universe. This allowed it to compensate for any deficiency that a person might have. For example, the Lu family had used it to compensate for their lack of spiritual force. What could Ancient God have compensated for?
Ancient God had never revealed his own comprehension of the Origin Sutra.
Lu Yin needed to completely reassess the man's strength.
As the leader of the Seven Skygods, there was no doubt that Ancient God was the strongest of them all. He was also most likely the most powerful of the Three Pillars and Six Skies.
There was no need to consider Ancient God for the time being. Lu Yin looked beyond the forest. "Just a little bit more. My inner worlds are transforming, which has let my strength rise much like it will when I break through and become a Progenitor. Why am I still missing that last little bit?"
"You want to break through to the Progenitor realm?" Hongyan Mavis asked.
Lu Yin shook his head. "It's not time yet, but my inner worlds have almost all transformed, which increased my strength almost as much as a breakthrough in my cultivation. Even so, I still can't suppress Feng Bo."
Hongyan Mavis asked, "Does there have to be a connection between transforming your inner worlds and a breakthrough?"
Lu Yin grew puzzled.
Hongyan Mavis looked down at Lu Yin's heart. "Truthfully, your current strength is unbelievable. Others cultivate in order to strengthen their inner worlds, while you transform yours, which is a new path. It is certainly impressive, but that doesn't mean you've actually had a breakthrough. What's the biggest difference between a Semi-Progenitor and a Progenitor?"
"Vitality," Lu Yin answered immediately.
Hongyan Mavis smiled, but said nothing more.
Lu Yin instantly understood. That was it, he was missing vitality.
Any cultivator with enough talent could reach the Semi-Progenitor level and develop an inner world. However, the following breakthrough to become a Progenitor had a critical requirement: Origin Matter.
In order for a person to become a Progenitor, they had to first open the three meridian points, and one needed Origin Matter to open the third meridian point. One could not become a Progenitor without that.
After rising to a level where he was constantly facing experts such as sequence powerhouses, and even Ortusers from the six Scourges, Lu Yin had nearly forgotten that one of the prerequisites to become Progenitor was to open the three meridian points and obtain Origin Matter.
He had already done this, which meant that there was nothing stopping him from becoming a Progenitor, but these requirements also revealed a distinction between Progenitors and Semi-Progenitors.
Several of Lu Yin’s inner worlds had transformed, but they still lacked vitality, which made them fundamentally different from a Progenitor’s world.
To achieve the distinctive power of a Progenitor, vitality was absolutely critical.
After all, it was the presence of vitality that made a Progenitor's world.
Xia Shenji’s Progenitor's world was filled with creatures formed from blades.
Arch-Elder Zen’s Progenitor's world lacked living creatures, and yet it had vitality. While his lonely path was devoid of any visible lifeforms, it still overflowed with vitality from the Origin Matter that the man had absorbed.
No matter how Lu Yin’s inner worlds transformed, without the necessary vitality, they would always be fundamentally different from a Progenitor's world.
Yes, that was the piece that Lu Yin was still missing.
However, how could he introduce vitality into his inner worlds?
Lu Yin fell deep into thought.
Beyond the bamboo forest, Feng Bo's sense of danger was growing stronger. Every time Lu Yin attacked, he was noticeably stronger than before, and on top of that, escape seemed impossible. Waiting in the Mirari Realm felt like awaiting execution.
No, he could not continue waiting. He had to leave.
No matter what, he was out of options.
Feng Bo picked a direction and started moving.
In the forest, Hongyan Mavis shot to her feet and looked outside with a strange expression, which Lu Yin immediately noticed. "Senior, what is it?"
Hongyan Mavis solemnly replied, "Feng Bo just entered a forbidden region."
