True, Cao Cao did use phoenix tears as a crutch in his fights. I'm just surprised because Cao Cao seems far stronger, seeing as even Issei had problems fighting him and Issei can beat Sairaorg. That's why I suspect they are talking about his Breakdown, in which case, yeah, as strong as Cao Cao is, I don't think he's quite Satan-Class.
