You Laugh at Me for Not Knowing the Price of Rice? I'll Build Cannons and Make You Submit!

Zhou Yi opens his eyes to find that he has transmigrated from the twenty-first century, where he was an engineering student, to a parallel world in the 1970s, where he's become a sent-down youth.

His mind is crammed with future scientific knowledge and a database of countless scientific luminaries?

He has barely finished collecting his bedding when he's dragged to a meeting room at Bureau No. 7 to bail them out?

Production of the Type 56 submachine gun has been halted, leaving the bureau in dire straits?

He casually suggests developing a mountain rocket launcher, only to be ridiculed for not knowing his place?

He unlocks a future technology database, and he's equally good at arguing with experts, revising designs, and building weapons!

Ma Xingsheng wants to dismiss the doubts?

Beep. Mastery of rocket launcher design principles. The director approves the project on the spot!

Li Yan wants to find fault?

Beep. Mastery of both materials science and ballistics. The chief engineer concedes defeat!

Thermobaric bombs, tactical nuclear weapons, Tiger tanks... He hand-builds powerful weapons that astonish China and the world!

The Americans and the Soviets are freaking out: just how much cutting-edge technology is this kid hiding?
