At that moment, Ling Xiao seemed to discover that the Hundred Insect Demon King had aged significantly.
Although this Hundred Insect Demon King is a being from tens of thousands of years ago, she hasn't lived until now continuously but has been reincarnated due to some opportunity.
It is highly possible that this Hundred Insect Demon King, like several other demon lords, had cultivated to the Reincarnation Realm, or even higher realms.
Only then could they have done this.
After being reborn, she had to cultivate her power from the beginning.
Generally speaking, the Sea Race's age is longer than the Human Race, but only around two hundred years old.
The Heavenly Man Realm cultivation can increase lifespan by ten to twenty years.
The Cave Heaven Realm cultivation can increase lifespan by fifty years.
The Yin-Yang Realm cultivation can increase lifespan by a hundred years.
So when you think about it, she only has about three hundred years to live.
