What was Longevity Aura?
The simplest example: under normal circumstances, the lifespan limit of the Nascent Soul Realm was one thousand years!
If a Nascent Soul Cultivator suffered severe injuries and damaged his foundation, he would not live to his natural limit. He might grow old and die at nine hundred.
At that moment, if there were a precious ten-thousand-year life-extending spirit herb, it could repair his damaged foundation and allow him to reach the thousand-year limit.
That was life extension!
On the continent, such precious spirit herbs capable of extending one's lifespan were exceedingly scarce and rare. Countless old monsters fought over them.
After all, along the path of cultivation, fighting and killing were as commonplace as daily meals. Who did not carry a few injuries?
Then what use was Longevity Aura?
When Longevity Aura entered the body, it could directly increase one's lifespan!
It increased it directly and could even break through the lifespan limit!
For example, if a Nascent Soul Realm cultivator obtained a hundred years of Longevity Aura, after refining it, his lifespan limit would rise from one thousand years to one thousand one hundred years!
"A single Lower-Grade Immortal Crystal contains roughly a hundred years of Longevity Aura!"
"And this Mid-Grade Immortal Crystal contains a full thousand years of Longevity Aura!"
Su Bai was astonished inwardly and could not help sighing. The Immortal Realm truly was the Immortal Realm!
With this Longevity Aura, the people of the Immortal Realm lived far longer than those of the Human Realm!
Of course, Immortal Crystals were incomparably precious. Not everyone possessed them; they were likely controlled by only a small number of people.
The same old saying applied.
In the same world, the strong were revered. Naturally, the rich would die rich, while the poor would die poor!
