Alien Invasion: My Future Girlfriend and I Save the World

If saving one person would make the world end sooner, would you still save them?

In June 2026, Liang Su, a senior at Yudu No. 7 High School, meets a barefoot girl in a white dress at the school gate. Her name is Jing Yu. She knows he hasn't taken his medicine, knows what he dreamed about last night, and knows that he will die in twelve years.

She's not human. She comes from a thousand years in the future, and only a blue core remains of her. It has taken root in his chest. She gives him a System: physical stats, System quests, and mecha blueprints.

With her help, Liang Su earns his first fortune, builds the mecha "Black Whale," and becomes the only person in the world capable of facing monsters head-on.

But he doesn't know that every technological leap humanity makes is a warning bell to aliens. The stronger he gets, the sooner the alien invasion will come.

And saving the world was never Jing Yu's real mission.

It was saving him.

Even if saving him means the world ends sooner.
