Kai still knew little to nothing about an Ending.
All he knew was from Noxian that an Ending is a part of a Nightborn's essence, which only he and the other children of the Final Night could learn. It was the end version of a particular mastery or understanding, unique to each Nightborn.
In order to complete the Ending, Kai needed to exactly do the work the Nightborn had to achieve that Ending.
Like the Perfect Slash Ending, in order to complete it, he was forced to endure the sensation of rigorously intense training in the slashing motion—for a hundred years. So that regardless of his condition, his slash would be perfect.
It was Noxian's own experience before achieving that ending.
Kai felt every struggle.
Muscles are burning from micro-tears. Bones breaking. And the mental toll was the worst.
Continuing to train despite wanting to quit put his mind through a long, hazardous odyssey.
Kai wondered what the way would be to fully complete the Stone Ending.
