You advice me to reread again, so i'm giving you your advice back to reread the part where Igneel said he developed the antibodies.

For starters, everything you said was a speculation yourself, i'm just replying to that. You said Natsu's increase strength is because of awakening as E.N.D and dragonification, so i ask back if Gray and Gajeel improve as much as Natsu has during that 1 year period, does it mean they are undergoing the same process as Natsu.
