Rui meditated in the Great Jrava Mountain Range.
Some distance away in a little hut was Master Gurren.
He had yet again been thrown under a pile of homework, cursing incessantly as he persevered through the assignments on the Parallax Method that Rui had supplied to him.
Rui ignored him.
He was focused on something more important.
Inside his mind, an ocean of information blasted through the mindscape of his Mind Palace.
"Rgh!" Rui struggled as he processed every packet of information, each containing a vector, magnitude, and direction.
Each packet was like a drop of water.
Yet there were so many that nothing short of a sea of information had been drowning him in his Mind Palace!
It was only more than an hour later when he managed to extricate himself from the sea.
He opened his eyes as he put the final piece of the puzzle together.
The puzzle of the past.
Time reversed as he bore witness to the past.
