Becoming the Apocalypse's Only Fourth Calamity

[I write very slowly. My main updates are on my other story, and this one will update occasionally. I'll write this one after finishing the other.]

Blurb 1:

Doomsday: Above the Ruins is the world's first large-scale open-world VR game, released by the 23rd-century company Eternal. It boasts a post-apocalyptic setting, an exceptionally high degree of freedom, and a wide variety of gameplay.

Yun Yue soon became engrossed after starting the game. She might have terrible luck, but that was fine: money could solve everything! As a hardcore completionist, she was determined to collect every achievement and title!

But as she played, she somehow triggered a quest no player had ever mentioned and received a chuuni title no one had ever heard of before???

Yun Yue stared at the game screen's [Last Hope: Mysterious Visitor] and fell into deep thought.

Blurb 2:

In 2104, volcanoes erupted on Blue Star, glaciers melted, tsunamis struck, and the climate changed drastically. Extreme heat and cold appeared at the same time, while plants and animals underwent massive mutations. Humanity was caught unprepared by the sudden disaster and suffered devastating casualties. The survivors built several fortresses on Blue Star to defend against mutated beasts and plants.

After a long struggle, humanity's extinction seemed inevitable.

But at some point, a legend began circulating through the cities: If you sincerely prayed in your heart, a strangely dressed mysterious person would appear before you and grant your every wish.

Yun Yue, who was just trying to complete every quest: ???

Read before starting:

1. The heroine grows stronger step by step, but she will never be mistreated along the way. Anyone temporarily stronger than her has less money, and everyone else is neither as strong nor as wealthy as she is. Once she levels up, she'll be the strongest person in the world.

2. The heroine always seems mysterious and powerful to other people. Even when she does things that are normal in a game but strange in real life, everyone else just assumes there must be some deeper meaning behind them.

3. Many people have one-sided crushes on her. The male lead is basically a background character.

Theme: As long as humanity endures, hope will live on.
