The main route from Desertopia (the 1x3 tunnel) to Guodesia is complete. It needs to be made to 3x3 at regulation standards now.
Cut out 2 1x3 tunnels on the sides of the main central 1x3 one (centered on the torches). Only cobblestone and stone walls, roof and floors are allowed. All visible dirt, gravel and ores will have to be replaced.
Any help is appreciated. You can keep the ores, cobblestone and whatever you get from the excavation.
As an added bonus, whoever makes me the happiest from doing this (whether that means doing the most, doing it the best or just doing it on a day when no one is helping out) will get 5 diamonds!
Have fun!
Beware: chunks near Desertopia are corrupted. So yeah.
