Countdown to Saving Civilization

In the year 5205, human civilization enters its final countdown.

To save human civilization, countless scientists exhaust their efforts and finally invent ten time-simulation machines.

These ten time-simulation machines can simulate all civilizations that have existed on Earth over the past billion years and use them to create a world of astonishing realism: Simulated Earth.

But each time-simulation machine can bring only one person into Simulated Earth during its entire existence. And once a Host dies in Simulated Earth, they will immediately be ejected from the machine and will never be able to enter again.

So! The Academy of Sciences decides! They must find ten young people who are healthy! Capable! And, ideally, proficient in all eighteen types of martial arts, to enter the time-simulation machines. By observing the rise and fall of other civilizations on Earth, they'll search for a way to save human civilization!

Wang Xiaoxi is an unemployed young woman who graduated with an ordinary bachelor's degree fifteen days ago and still hasn't found a job. She spends her last cent to save a stray kitten.

She looks at her empty wallet and sadly wanders through the busy city streets, when a flyer suddenly falls from the sky.

"Still worrying about finding a job? The Academy of Sciences is waiting for you! All you need is good health, a sunny disposition, and an age between 20 and 30...

Time: June 20, 2524

Location: Academy of Sciences, 1 Kejijie Street, City B."

Wang Xiaoxi: !!! A job from the heavens!

Inspired by her admiration for the Academy of Sciences, her trust in the country, and her longing for a secure government job, Wang Xiaoxi sets off without hesitation to interview at the Academy of Sciences!

Before the interview: Hehehe, here I come, secure government job!

After the interview: It's over. That secure government job just hit me on the head...

In the end, the Academy of Sciences coaxes and tricks Wang Xiaoxi into the time-simulation machine, forcing her to embark on a solitary journey to save human civilization...

She explores the secrets behind the succession of civilizations, the causes and effects of the cycles of all things, and painstakingly pieces it all together, solely to seek a future for her home...

In a nutshell, this is the story of how I just wanted to eat my fill, but you all wanted me to save the world. TAT

Note: The time-simulation machine is similar to full-dive technology. The story as a whole is like a quick transmigration novel, and Xiaoxi experiences four civilizations.
