when the story starts, does superman say that for his situation (hes dying), are 3 things that did cause it. one is the fire of apokolips, that one i get it because its from the justice league comics before rebirth. the 2nd (the kryptonite cell from argus) and 3rd (his fight with rao) i dont get them at all beause i missed them to read. but what did exactly happen? and where can i read about the situation with argus and rao? are both in the action comics? or somwhere else?
