After reaching Divinity Transformation, it is actually possible to change one's appearance, and maintaining eternal youth is not difficult.
However, his current appearance was purely a sign of Life Span exhaustion. Even if he consumed any Youthful Appearance Pill or similar miraculous Spirit Pills, he couldn't change his appearance. Even if he could, it would only be temporary, and it would be very easy for others to see it wasn't his true appearance.
Moreover, his Nascent Soul Cultivation aura was clearly strong, yet his Life Span was so short... Very strange...
As the Taoist couple of the Old Ancestor, an unmatched Heavenly Pride of the Nine Provinces' younger generation, a Cultivation prodigy who reached Nascent Soul after just over a decade of Cultivation—was he really about to die? What a joke...
"Has your Old Ancestor left seclusion?" Wang Mu asked with a smile.
Granny Gu shook her head.
