Namibia

Namibia's Kalahari Desert is also known as the "dry lake" at the end of a very short stream, and although several water systems flow through it, no water has ever flowed into the ocean from here. The stream flows into the depression in the desert, penetrates and evaporates, and disappears without a trace. Beneath this dry and barren Kalahari Desert lies a huge natural "reservoir" hidden. In 1986, an expedition team discovered this place, and when standing at the mouth of the cave, a damp breeze blew out from the inside, which is the origin of the cave's name "Dragon's Breath Cave". The depth of the lake is not bottomless, and the exact depth is not yet known, and it is said that it is at least 100 meters. Dragon's Breath Cave is home to the world's largest underground lake, and such a huge cave is only part of the Kalahari Desert underground cave system, which is a wonder of the world.
