Anyway, the time altering feature isn't going to make it easy. Both times Bee got caught into genjutsu, he experienced their effects for a while before Gyuki dispelled it. These were mere seconds, yeah, but as I already said, even 1 second (even some fractions of a second, if we include Itachi Shinden novel feats) is enough for Tsukuyomi to damage the victim's mind.
