I {Alan} am an abandoned citizen on the edge of the black hole. I am squeezed out and suppressed by Gray, the cunning village leader. Even Ella, the former White Moonlight, becomes his accomplice. The apocalypse is coming, AI rebels and devours interstellar civilization, and mechanical monsters run rampant. I accidentally bound to the [Doomsday Safe House System] - upgrade the safe house, recruit survivors, and cultivate followers to unlock divine power and black technology! Although I am dull on the surface, I secretly use the system to develop: strengthen the fortress, exchange weapons, and recruit skilled craftsmen who were persecuted by the village chief. After encountering Leah, a mechanic with a peerless appearance, I found out that she hid the core secret of AI rebellion. The village chief teamed up with his accomplice Buck to covet the safe house, and Ella went undercover to disrupt the situation. As a mortal, I borrowed the power of the system to build the last pure land on the edge of the black hole, beat the mechanical monsters, tear apart the scumbag men and women with my hands, and finally counterattacked from the abandoned people to become the co-owner of the universe!
