On the training field, Kasumi Miwa stood frozen in place, gripping the sword in her hand.
"Black Flash with every strike?" Her voice sounded dazed.
Kasumi Miwa felt that Jie Jian had to be joking with her.
Putting aside how difficult it was to trigger a Black Flash with a weapon, even if it could be done, there was no way every slash could be a Black Flash!

Kasumi Miwa thought for a moment, then hesitated.
"Uh... the interval between cursed energy and the physical attack can't exceed 0.000001 seconds?"
"Isn't that
