A few more years passed in Cedric's trials...
His progress consistently increased; he could now fight against Master Ye for 15 hours straight, and he could also endure staying at the Pit of the Abyss for more than 16 hours. As for his progress with the Nameless Sword Technique...
Swoosh!
That's what he's focused on right now. He's on the verge of mastering the 7th move, meaning that he has already climbed the 7th mountain on the trial of his mind.
Sure enough, the farther he goes in his practice, the harder it becomes. Although the Nameless Sword Technique looked extremely ordinary and basic on the surface, it's actually very difficult to learn and do properly. Cedric can't rely on his luck to enter the state of enlightenment again. That state isn't something that will come just because one wishes for it to happen to them.
