Several men have great comprehension, presumably their aptitude is not bad either.
Thinking that perhaps they should join me in cultivation, achieving immortality, strengthening their power to soar through the skies, move the earth, and overturn rivers and seas.
Although the Beastmen generally have a longer lifespan than humans, they don't exceed 200 years.
Only extremely powerful and formidable Beastmen can achieve that.
Above 100 is already considered very old.
The situation in Aetheria isn't clear, but at least here in The Lower Domain, including the Wolf Tribe, there isn't any Beastman over 100 years old.
Ordinarily, they are too old to chew meat by seventy or eighty.
Cultivation is different; once reaching Foundation Establishment, they can live for 200 years, and at Golden Core, their lifespan doubles.
Beyond that, with great power, living for several thousand, or even tens of thousands of years, or equating their lifespan with the heavens isn't impossible.
