Surviving Underground: Super Prompting System

Upon waking up, six billion people were scattered and transported to the enclosed depths of the underground. Every single being was in a cellar of only a few square meters, with only a shovel beside them. They were fully surrounded by dirt, rocks, and terrifying monsters that would tunnel out from time to time.
In order to survive, people began to dig around in seek of a chance to survive. Some dug up food and water, some dug up quilts that could keep out the cold, some dug up a terrifying Ogre and then got devoured, and some dug up lava and were burned to death… Joseph was one of them, but by good luck, he awakened to the [Super Prompting System].
[Dig 30 meters up and you will find a box of canned beef]
[Dig 15 meters to the left and you will find an arsenal for guns]
[Be careful to the right. Dig another 20 meters and you will perish due to poisonous gas].
When everyone was digging carefully and many even paid their lives, Joseph was already fully equipped, hunting down various monsters with guns every day, and making a name in the underground world.
