Doomsday Sign-In: I Became the Lord of the Shelter

The protagonist, Chen Lin, transmigrates to Kyoto in the parallel world of Longguo and is bound to the Divine Shelter System. A sign-in rewards him with a god-tier shelter and an AI named Zero. Ten days later, the apocalypse begins. Extreme cold, scorching heat, floods, meteorites, and other disasters strike one after another, and the world falls. Zombies run rampant, but Chen Lin hides a shelter in a mountainous area. As the world order collapses and civilization retreats, only the System and his shelter remain as humanity's last spark. Here, he doesn't rely on passion, only strength and resources. And he is destined to control everything from the shadows.
