Indeed, in a sense, this young girl could be considered a daughter Pan King had gained late in life, though old age did not really exist for an Immortal King.
As a supreme Immortal King, Pan King had attained his Dao only within the last few eras. Among the myriad worlds of the present day, he was still quite young for an Immortal King.
Those who deserved to be called old fossils had to date back close to the Emperorfall Era, a considerable stretch of time before even the King-Sealing Era, when the Primeval Ancient World had risen again. So much so that, apart from the name Scale-Removal Fall, the remaining eras were little known.
Pan King was a peerless prodigy born when an immortal medicine of longevity gained spiritual awareness. Most immortal medicines of longevity came into being after an Immortal King died, while a few were nurtured by heaven and earth. Some medicines that surpassed divine medicines but barely approached immortal medicines of longevity were also placed in this category. These weaker immortal medicines of longevity came from Quasi-Immortal Kings who had already set half a foot into the Immortal King realm.
As for undying immortal medicines, most were formed after the deaths of True Immortals, while a portion were nurtured by heaven and earth.
When the Age of Dharma Decline arrived, heaven's will would cut down the status of immortal medicines of longevity, turning them into undying immortal medicines.
Pan King had been a Flat Peach Tree nurtured by heaven and earth, an immortal medicine of longevity. After gaining spiritual awareness and taking human form, his talent had been unparalleled. He had become one of the central figures several eras ago, sweeping all opposition aside in his domain and attaining the Dao Fruit of an Immortal King.
