My Girlfriend Is 3,000 Years Older, and the Whole Country Is Helping My Online Romance

Jiang Chuan starts an online romance with a short-tempered "factory girl" who says she spends her days tightening screws at the factory.

Then one day, she mails him a "flashlight" for self-defense.

That night, Jiang Chuan tests it in his dorm. A beam of light blasts straight through the surface of the moon, setting off air raid sirens around the world!

The National Academy of Sciences storms in in the middle of the night. "You call this a flashlight? It's a Dyson sphere core-fusion cannon!"

Jiang Chuan is dumbfounded. "She said it used too much power and called it defective..."

To get blueprints for even more advanced "defective products," the nation establishes the Interstellar Romance Strategic Bureau.

"Comrade Jiang Chuan! For the sake of our sixth-generation fighter jet, please get her to send over a few more 'lighters' (ion thrusters)!"
