Following the direction the giant had pointed, Di Tou soon found a building that, for all intents and purposes, looked the same as all the other smithing buildings but had a slightly metallic silver sheen, as well as the character "Earth" on it instead of human. Standing at the entrance, Di Tou hesitated for a moment before knocking on the door, only to quickly pull back his hand while grumbling, "What the h*ll? The door is hot like an oven…"
Seeing that no one opened the door, Di Tou hesitated for a moment before calling out, "I'm coming in. Please excuse me." And pushing open the door. Pushing against the doorway, Di Tou once again felt a surge of heat, but it was quickly offset by the protective energy. Feeling this change, Di Tou couldn't help but feel a little startled before roughly understanding it should be a test of some sort to keep the normal disciples away from the Earth Grade rooms and take on more than they could handle.
