There is no need for lighting in hell.
This is common sense for all Terraria players.
Because the surging, ceaseless, blazing lava constantly emits light and heat, illuminating the entire hell, there is no need to waste torches.
But in the live broadcast room of the bandits, hell looks almost indistinguishable from ordinary caves, and almost not a drop of lava can be seen!
At this moment, only dense torches and neatly arranged bonfires can light up the environment.
It was the light of these torches that allowed Warehouse Bird to see the familiar Hell Ruins and confirm that this was indeed hell.
Unlike the many confused audiences in the live broadcast room, Warehouse Bird carefully observed the environment and understood how these people did it.
Actually, it's not complicated at all: release water.
There are two mechanisms that are identical in both "My World" and "Terraria".
One is: when lava meets water, it turns into solid Obsidian.
