Do Androids Bite Circuit Boards?

Luo Yinuo scrapes by as a scavenger-turned-scientist in a future where freeloading aliens threaten Earth's borders. When the military commissions a weapon to stop gate-crashers but refuses to pay upfront, Luo does what any broke genius would do: goes absolutely overboard. The result? A doomsday device capable of obliterating planets if the safety's off. Now Earth has the ultimate deterrent—and a ticking time bomb in the hands of a scientist who just wanted to pay rent.
