"She" made sense, but since Shard had proposed the idea, he naturally had his own considerations:
"As long as I try the Arcane Technique while rolling the dice, theoretically, the probability that luck will affect the Arcane Technique is very high."
He looked at the street scene and said to himself.
[But what if the result of the dice is misfortune?]
"That's exactly what I'm saying, I've been contemplating this for a long time, and in principle, it's feasible."
Shard crossed the street, pretending to chat with passersby, but most of his thoughts were focused inward. He came up with a rather bold idea:
"You once said that you could rebound attacks from fate, thus turning misfortune into good fortune."
[Yes, but no one is attacking you right now.]
"No one... if luck is rolled, there is no issue. But if it's misfortune, that misfortune will affect me, then can you rebound it into good fortune?"
He asked cautiously, then heard her pleasant laughter:
[A very good idea.]
