Different races have varying lifespans. Take humans, Feather Tribe, Black Scale Tribe, Centaurs, and Dark Night Elves for example; the lifespan of Dark Night Elves is undoubtedly the longest, with an ordinary Dark Night Elf reaching around 350 years.
And ordinary humans only live up to 120 years, placing last among these five races.
It was not until the birth of sorcerers that this disadvantage began to turn around. A Level 1 Sorcerer can live up to 300 years, Level 2 up to 400 years, Level 3 up to 500 years, an Arcane Wizard up to a thousand years, and the Void King around two thousand.
Compared to the way of the sorcerers, the path of the Knights is far inferior. A Level 3 Flying Knight can at most prolong life to 200 years.
Knight King, according to the remaining records of the Centaur Race and calculations by Ivan, the lifespan of a human Knight King should be between 500 to 600 years, and that's under the influence of the legacy power from the Justice Star Ancestor.
