Moments ago.
As soon as Mark sat under a tree's shade, his ken (understanding) leapt by leaps and bounds. His understanding with his sword had reached its limits, or so it seemed, because whenever he tried to understand more about the way of his sword, something fragile seemed to be blocking his way.
It felt extremely easy to break through; it even seemed to be within his reach, yet the reach seemed to be infinity long.
When he gained his enlightenment just recently, the blockage broke, shattered into pieces. Thereafter, nothing really changed except for him feeling light headed whenever he swung his sword.
Ideas and thoughts on how to improve his sword slashes further, constantly appeared in his mind, making it harder for him to complete even a single slash that dealt the most damage amidst of his train of thoughts which were numbered in trillions.
DING!
