Protagonist: Lin Chen, an unemployed low-level social worker; bound to [Great Power Heavy Industry·Black Technology Shenhao System], funds can only be used for scientific research procurement, experimental research and development, and private consumption is prohibited; the purchase of special materials at the beginning triggers risk control and is registered by the police; seven categories of front-end black technology are unlocked at once at the beginning: miniature civilian controllable nuclear fusion reactor, seventh-generation graphene superconducting battery, nano-bionic hydrophobic coating, Ultra-fine grained titanium-aluminum alloy, micro electromagnetic damping and shock absorption system, micro nano laser cutting module, low-temperature plasma silent propulsion components; relying on the popularity of live broadcast research and development to unlock high-end blueprints, all the way from grassroots researchers in rental houses → official cooperative scientific research talents → national-level heavy industry pillars → interstellar technology leader, hiding the system throughout the process, low-key pretending to be a pig and eating a tiger, a series of slaps in the face, and the national fortunes are promoted in parallel.
