I think Chung mung said people who train blah blah age older because of their abilities. If we look closer at Chung Mung from the past we can see that his little hair that sticks out is white.
He is OLD old back then! Also in case you don't know and if it concerns you or something as far as the latest novel update there is no romance around the mcლ(´ڡ`ლ)
OMG NO ROMANCE?? THIS IS THE BEST
Huh, I assumed it's there only to separate the current one from the past (/to make it easier to recognise which is which)
OH :0! I see tahnk you for that
OMG yesss it's always the no romance ones that i love the most
I don't think so. Him from the past wears a different outfit from the one he wears right now. His friend also had some white hairs.
Bro i didn't know he was 80 in his past life? Did i overlook it or was he just saying that he's old OLD back then
