Global Disaster: I Have a God-Tier Shelter

Global Cataclysm: meteorites fall, volcanoes erupt, glaciers spread, the planet’s core shakes, and underground beasts swarm across the human world... Don’t panic, the God-Tier Shelter System has been activated. The shelter has not only an agricultural base for growing crops and raising livestock, but also a research base for building all kinds of combat robots. Now, follow me as I lead an army of a million robots to strike back against the beasts and march into the stars.
