the gate is open, its already 4 years when the gate first appeared, gates are breaking when its not cleared during 7 days then monsters will come out of the gate, so right now they're all over Jeju Island, he doesn't need to go inside or open the gate anymore
And the main character open the gate ... meet with ant and slaughter them lol
I hope ٩(๑❛ᴗ❛๑)۶
