Mine Survival: Build the Fourth Reich!

[Survival for all], [Underground Mine], [Farming Construction], [Empire], [Invincible Style], [Multiple Heroines], [Decisive Killing], [Brainless Fun], [Card Drawing], [With Pictures]. Once you travel through time and enter the world of national survival, billions of players around the world are trapped in narrow mines. Oxygen, water, food... Things that were originally ordinary have all turned into extremely precious survival resources here. Everyone is racing against death. However, Mu Ran awakened to the plug-in card drawing system at this time, with each level drawing 10 cards in a row, and her luck was even worse. From then on, Mu Ran's survival style changed drastically. Other players were worried about eating and drinking, but Mu Ran had already drank Coke and had self-heating hot pot, not to mention oxygen.

Develop technology, build transportation lines, arsenals, engineering robot workshops, and even independent entertainment facilities. Ever since. A whole civilization system is gradually taking shape in this underground world...
