Rooftop Starship: Agent of Earth - Starship in space as seen by Starlink

Astronomy streamer Zhou Ye witnesses a mysterious craft vanish from every satellite record on Earth. That same night, the ship—compressed to the size of a car—lands on his rooftop and offers him a contract as Earth's planetary agent. Its fabrication bay can build technology centuries ahead of humanity, but Zhou must complete seven civilization missions before rival alien agents identify him. From a secret rooftop workshop to a global technology empire, from covert urban warfare to chases across near-Earth orbit, Zhou overwhelms the old order with impossible inventions while uncovering a darker truth: the missions are not a gift, but a trial imposed by a cosmic system that decides which civilizations deserve a future.
