The giant valley, surrounding the small village, was covered by ice and snow. The valley could protect the village from blowing away by the snowstorms raging outside. However, every coin has two sides, and though the mountains could protect the village, it could also bury the village under the snow and ice because echos and sounds in the village could lead to catastrophic avalanche. Being eroded, the mountains and also the valley were disappearing, and eventually they would break into pieces, causing the village to be eliminated. The day of the collapse of the mountains was called “The Judging Day”. Villagers were busying in discovering ways to survive from the Judging Day. Before the world was covered by snow, the sea level rose unexpectedly, and some of low-lying lands were converted into shallow water. When the temperature fell and the earth froze, water turned into ice. A piece of land was converted into icy platform, and the place was called by the villagers “The Giant Lake”. The lake was in fact, an unexpected food source for the villagers that dead fish sometimes emerged from the icy platform, eroded by the snowstorms. Since it was icy outside, people did not know why the fish were People dug a well directly towards the center of the earth to search for magma, which is considered a potential source of heat. However, they already dug for 50 kilometers but still there was no magma. Not even heat was discovered by scientists. People wanted to go into the well to figure out whether there was heat underground, but still no one was brave enough to conduct the experiment.
