Sorry, but thats a complete lie. Its not hard to farm up that much wood. or any other material.
If I had taken screenshots of what I had in my base before I let it all go, you would scream at me for days. Just off the top of my head, I had about 75K steel reinforcements, 130k steel bars, 60k shaped wood, 150k hard brick, I think like 9 chests of obsidian bars, 8 or 9 full of star metal, 70-80k hard steel, about 7k explosives, over 1000 named thralls including 120 arch priests etc.
When you play on a server for a few years with a group of people…its not hard to accumulate things. PS, this was on a pvp server.
