Doomsday Livestream: My Shelter Connects to Another World

The world is frozen over, and while everyone else struggles to survive, I use a back door to a xianxia world to livestream sales of down jackets and self-heating hot pots, becoming richer than the whole planet. As the world freezes over, a livestream System forcibly binds itself to me. Lin Mo watches everyone else's plight, calmly opens the basement door, and reveals sunlight and lunch from another world. The livestream chat goes from skeptical to explosive.
