Whenever we listen to mythological stories, there is talk about a different world under the earth i.e. Hades. It is believed that demons used to live in this dark world. Till now these were just stories, but one person really discovered another world under the earth. It is 262 meters below ground level and is not a small place but a different world.
No one knew the place we are talking about when a person saw it for the first time. While he was wandering in the jungle in search of food and water, he found a mysterious path in Phong Nha Ke-Bang National Park, Vietnam. He went inside the cave present here. Although he had no expectation that this mystery and this discovery would become historical.
There was a different world inside the cave
A boy named Ho Khanh reached inside the cave in 1991 in search of food. He thought that he would get something to eat here, but he started hearing strange sounds. It was like the blowing of a strong wind and the gurgling sound of a river. Since he had reached 800 feet below the ground, he got nervous and turned back due to fear. He had even forgotten that when he met Howard and Deb Limbert of the British Cave Research Association, a cave research organization. When he talked about the cave, even the researchers were stunned.
