Usually the old chapters are left up, they just aren't updated anymore. There'll be a link in the "Read or Buy" section that says "Offical English" you can go to.
Happy Memorial Day everyone! I am… 30 minutes late! When I started working on this, I didn’t know much about Galaxy Degen… now I know way more than I ever thought I would. Thank you Dortex for the help on this. And good luck to the next group... On to the next abandoned Manga! See you all then :-D
Btw I'm not updating this anymore (lol after only one chapter) because as it turns out, they're already translated on their Twitter (original) (translated)
