From the Phantom Master's mouth, it was known that he originally belonged to the Ghost Clan, cultivating into a Stage Five Rakshasa, having ascended from a malevolent ghost step by step, which was indeed astonishing; this fellow possessed exceptional talent.
With the constitution of a malevolent ghost, reaching this stage without perishing indicated both good fortune and strength. However, as the years stretched on, his malevolent ghost constitution reached its limit, signaling the approach of his end.
If he could ascend to King of Asura, there might be a chance to prolong his life, but the gap between a Stage Five Rakshasa and King of Asura was too vast, therefore, the only thing waiting for him was a dead end.
Who could have imagined, just as he was about to perish at his end, suddenly a person calling himself Dr. Kun appeared, transforming his rotting physical body into a mechanical one, and injecting it with new energy, namely the Astra Indra Core.
