Im trying to find an english webnovel, probably read it on rrl years ago. Neet and his home/bunker and years of supplies is thrown into some kinda apocalypse. Also he raises a tiny dragon that he found in an egg somewhere
Ten Realms/Two Week Curse only one that comes to mind which transmigrates with a bunker. Only the first "realm/volume" is available on RR, rest are on Amazon.
