When Sherlock was planning the excavation of Eternal Kingdom, he used the Dungeon Core as the origin. In the southern direction, the regional blocks were connected to form a tunnel. In the direction opposite the Dungeon Core Main Hall, there was a two-hundred-meter wide tunnel that was used as a central tunnel.
The two-hundred-meter tunnel looked more like a plaza since the length was less than a hundred meters.
Though the gamers worked day and night over the course of a month, excavating, carrying bricks, and leveling ground and walls, Sherlock's priority was to create functional rooms or regional blocks.
For example, Food Storage, a Goods Warehouse, Seedbeds, a Carpenter Workshop, Training Grounds, and the gamers' Residential Area.
The space behind the Dungeon Core Main Hall could be developed, and there was a tunnel leading to the outside world.
Developing a Dungeon wasn't merely about excavation. Sherlock's plan wasn't like that.
