地下腐化之地

The Underground Corruption is a biome. It is the underground version of the surface-level Corruption. Prior to Hardmode, it will only naturally exist in the lowest parts of Chasms, and only if they are deep enough to reach the Cavern layer. Regardless, once the Wall of Flesh is defeated, more Underground Corruption will be created at and below the cavern layer. It operates similarly to surface Corruption, being composed of Ebonstone and Ebonsand, though it spawns different enemies in Hardmode.

地下腐化之地蔓延方式和地表腐化之地一样，同样也不能通过神圣之地蔓延。另外，可以通过打破恶魔祭坛来创造一小块地下腐化之地，在其被毁坏时，它会将世界中的某一块随机石块转化为黑檀石。

Underground Corruption does not suppress the spawn of other underground and cavern enemies. During Hardmode, all enemies killed in the Underground Corruption have a 1/5 (20%) chance to drop a Soul of Night. In Expert Mode, this chance increases to a 9/25 (36%) chance.

在Nintendo 3DS version中，地下腐化之地的音乐被地下猩红之地的音乐所替代，因此，地下腐化之地的八音盒在Nintendo 3DS version中是无法获取的。
