She was a combination of a high iq scholar and a black-bellied prince charming. She was a one-on-one, two-on-one, two-on-one, absolutely refreshing, and she was welcome to jump into the pit.

In the second year of the apocalypse, Du Yue died alone, killed by apathy and exposure to extreme weather. Somehow, she opened her eyes to find herself not only alive, but also back when it was three months before the apocalypse. Despite the surprise, she thought about the upcoming disasters and upheavals. First, it was the fog that carried a virus that stayed for a month.

Then, global temperatures rose to over 120 degrees, evaporating most of the world’s water and melting all the icebergs. After that were level-10 earthquakes, cyclones, tsunamis, permanent eclipse, and avid rain… and that was not all, because after global warming, came global freezing. As temperatures dropped to below negative fifty, the savagery humans displayed was far worse than any imagined horrors like zombies! Knowing what was coming, Du Yue sold off her family property and used the pocket dimension her mother left her to hoard as many resources as possible, so that she could survive the apocalypse. Meat? Grain? Oil? Spices? Weather gear?

She bought everything! Steaks, French fries, spaghetti, and canned food must all be stocked up! To He Xing, the male lead, she was a god and the key to surviving the apocalypse!
