As disaster was about to strike, a group of survivors transmigrated into a desolated world and were challenged to a game of survival. From terrifying acid rains, to endless natural disasters, the heavens burn while the earth scorches, radiation is rampant, and nobody is spared from the dangers of this hellscape. The only way one survives is by building a shelter and slowly upgrading it in hopes of surviving another day. 
Luckily, Su Mo awoke a Doomsday Survival System that allowed him to infinitely level up and upgrade his shelter! The main shelter wooden door can be upgraded into a metal door, which in turn upgrades into a composite gate; the wooden spears can be upgraded into bronze spears, which eventually upgrade all the way into electromagnetic spears... While everyone struggled to survive, Su Mo was fully loaded, and well equipped to dominate the post-apocalyptic world. 
"While some of us are lighting oil lamps, he's been using refrigerators!" 
"The walls in his shelter alone are tens of meters thick, it's the safest place on this planet."
"Before I die, I wish to spend one day in his shelter..."

Great Mountain was just an overall term for this area.

The area was covered with thousands of mountain peaks and ridges that spread for over 10,000 miles.

It would be impossible for a human to count the number of peaks gathered in this area even in a whole lifetime.

Not to mention that after the winter, the size of the area would double again.

The mountain entrance was 400 kilometers journey in the southeast direction from the basin. There was a two-kilometer tall mountain that appeared before them.

The peak of the mountain was marked as First Mountain on the map.

This meant that it was the closest mountain to the basin and the first mountain they would encounter inside Great Mountain.

Without the powerful construction power of modern civilization, there was no chance that there would be a road for them to climb the mountain.

They did not have many options to climb over the mountains.
