In the Scorching Apocalypse, I Built an Underground Shelter and Claimed the Future for Myself

The global temperature suddenly climbs by 85°C. The scorching sun burns cities, water supplies run dry, and a high-temperature apocalypse begins! Lu Dong is reborn thirty days before the disaster.

Together with the one he loves, he takes refuge in this underground haven, keeping wolves at bay and riots under control as they enjoy a peaceful life in the midst of a living hell!
