Back to the end of the world: I rely on hundreds of millions of supplies to defeat natural disasters

Description

At the end of May, an acid rain kicked off the end of the world.
Extremely destructive natural disasters such as extreme heat, heavy rain, earthquakes, tornadoes, and tsunamis followed one after another.

Chi Yue was like a withered duckweed, struggling to survive for six years, and finally died of an insect plague virus that had no cure.
Open your eyes again and go back to two months before the natural disaster struck.

At this time, her husband, who was drowned in the flood to save her, was still alive.
She sold off her assets and stocked up on supplies, vowing to hold his hand tightly to survive the coming natural disaster and never make the same mistake again.
