"Three? Four? How was that supposed to be explained?" Yang Chen asked, puzzled.
Yu Ban had nothing to hide from Yang Chen and said with a chuckle, "The precise three realms are the Spirit Disk Stage, the Golden Venerate Stage, and the Body Integration Realm!"
"The Spirit Disk Stage, Golden Venerate Stage, and Body Integration Realm?" Yang Chen murmured.
"Yes. This is the process by which a Great Emperor grows. Young Master, did you know before this that once one reaches the Heavenly Martial Realm peak, the evolution of true qi has already reached its summit and will no longer advance?" Yu Ban said.
Yang Chen nodded. He did know something about this.
Starting from the Spiritual Martial Realm, true qi underwent a qualitative transformation with every increase in realm. But upon reaching the Heavenly Martial Realm peak, that transformation also reached its limit and could advance no further.
"Therefore, it became impossible to raise one's realm simply through the evolution of true qi. But in the Ancient Era, how could merely reaching the Heavenly Martial Realm peak possibly contend against all the major races across the continent? To the Ancient Era, the Heavenly Martial Realm peak was still somewhat too weak. Thus, the great powers of ancient times researched a new path. They gradually gathered the true qi cultivated within their bodies over many years into a single point, then used external objects to slowly condense it into something tangible. Though the process was incomparably difficult, once it took shape, it underwent a new transformation. That condensed essence of true qi was called a spirit disk!" Yu Ban explained.
"A spirit disk?" Yang Chen said under his breath.
"The spirit disk is a symbol of a Great Emperor. Anyone who cultivates one has already surpassed the Heavenly Martial Realm.
