Military Industry in the 1970s: The Mechanical Genius Goes Viral by Roasting People

[Transmigration + space + superpowers + strengthening the military industry + sharp-tongued heroine + sweet romance] Top mechanical genius Su Yue wakes up to find she's transmigrated into the daughter of a soldier sent down to the countryside in the 1970s! From the start, it's hell mode: her parents are suffering at a labor reform farm, and she's a young educated youth in the countryside.

While other transmigrators strive to get ahead, all she wants is to lie flat and live off her parents! But she's surrounded by the worst sorts: a village bully who skims her rations? She tears into him! An educated youth who makes snide remarks? She tears into them!

Luckily, she's got secret weapons: a supermarket space where she can secretly snack to her heart's content, and lightning powers to deal with anyone who dares defy her. She wanted to keep a low profile, but her abilities won't let her. She casually fixes a tractor and leaves the whole village stunned; she improves a tiny component, and military industry bigwigs come knocking!

To get her parents out of that living hell, this lazy fish is forced to get to work! Build a plane? Easy! Build a missile? No sweat! Build an aircraft carrier and a nuclear submarine? Fine, but I'm retiring as soon as this is done! Su Yue, who only wants to lie flat, somehow becomes a national treasure and a top military industry genius, racking up medals and rising to the very top!

The stoic soldier king Lu Zheng: This woman is arrogant and bold, yet unbelievably talented! Protecting her becomes the sweetest burden. Together, they take on the wicked, deliver face-slapping justice, crush enemy spies' schemes, and write a legend of their nation's rise to greatness!
