I don't understand.... How will Hayan giving blood to Euntae save him?? When Hayan's parents gave blood to Yohan, he just became a normal vampire and not a pure blood.... He had to eat their heart to get the powers and longitivity of a pure blood..... I know that Euntae's a vamp already and could be some kind of upgrading on having Hayan's blood.... But I'm I missing on some detail? As far as I know, a pure blood's heart must be eaten to get their powers and it is only pure bloods and half pure bloods who are shown to have a normal lifespan...... Pls let me know if I am missing something.....
