More than three months had gone by. Rui's life had turned into an intense monotony of dungeon clearing, both as Rui and as the Voider, gathering information on the Root, and training with Project Forestep.
Rui had dedicated the entirety of his mind and body towards mastering as much of the Godspeed Breathing technique, hoping to gain as much of this power as he could.
Unfortunately, as good as he was with breathing techniques, he was not as good as Kane was with speed and thus was unable to reach Kane's level of mastery of the technique.
After more than three months of dedicated training, his growth had finally plateaued at about forty percent of the full level of mastery.
