@SSDCZX if that old man indeed him, he probably 100+ year old
but its possible tho... remember this story not on 'our earth'..... there's many people got live long enough on there...
and this glasses guy still young on MC original timeline, and on alternate timeline MC got married at young age and die 2 month later...
MC's kid probably only few year younger (like ten year or more) than him...
@Goldenzeal I am mostly saying they are doing time travel correctly, because the method they are using is able to avoid all the issues with other time travel methods. By not actually time traveling, but traveling to an alternate world that's current time is at an earlier point than theirs. I will only have a problem with it if they don't keep a 1 to 1 time scale, without a consistent time dilation explanation.
Tip for everyone. This is probably the best arc so far. I am currently rereading,. I audibly groaned when I saw Great Granddaughter, but this is probably my favorite arc.
Not only do we get to finally see more of best waifu Lil Quan, but there is awesome action as well. Old versions of favorite characters. And, Evan is also there, and he is better than all previous Evans.
Really, I did not give thsis arc enough credit the first time around.
