You would be fried to a crisp. Lol.
It was just the other day I was looking up the deepest Wells ever dug on earth. The Soviets dug the deepest well or board the deepest well whatever you call it. It was about 12 miles deep and it took them several years. The United States had one that went about 8 miles.
The Soviet one had to stop when it hit some kind of molten sulfur or something like that. But it gets super hot when you start getting down a few thousand feet.
So nobody's really gotten past the Earth's crust I don't believe. Or the mantle or whatever it's called.
