A day began as usual - with marble. Player D. was in a better position - he had one Dragon helping him. An almost perfect situation for us: Dragon killed Marble golems, harvested them, and Player D. just had to wait untill I am full, take marble slabs and return when I am full. A conveyor, so to say.
And it worked. We just harvested anything we could, taking almost no rest for some hours. Finally 2 silos were filled with marble slabs and I brought some 1600 slabs with me. Result: almost 7000 marble bricks, and 1,75 level gained.
Then I took some rest and when returned gathered more slabs, almost filling one silo and leaving some 2000 bricks, gaining one more level.
Our teamwork had produced good results: work was fast and efficient, I did have fun with crafting and levelling up. And so the day ended with me advanced by two levels, gained some trophies from killed golems.
If things goes this way, Player D. will make his 86,000 marble bricks very soon and I would be happy to have helped with with that.
