Using Terraria mods to destroy the TRUE hardest block ─ It wasn't Chest, it's Temple Door!?

What is the hardest thing in Terraria? More specifically, what is the strongest block that cannot be broken by typical means? While there are no bedrocks in Terraria, but there are some strong objects in Terraria, like the lihzhard brick. I know what most are going to say though: Chests. Even more specific, Chest with any item inside. For some reason, Terraria really don't like players from destroying their storage with items in it. Many only talks about the Chest, but we have been neglecting something... something that's actually stronger than the chest... well, maybe. maybe not. Jungle Temple Door in Terraria is somehow, the strongest object in game. And I tried to break it by using vanilla items, Calamity mod like Crystyl Crusher, and of course, Echdeath... Wait, do you hear the tactical nuke dropping?
