[Great-Power Technology + System + Alternate Universe]
Chen Bo transmigrates into the body of an eight-year-old boy in a parallel world and obtains the Black Technology Superpower System. Every time someone likes a technology he has developed, he earns System points, which he can use to draw blueprints for all kinds of black technology.
He draws one black-tech mystery box after another: paper drones, a controllable nuclear fusion power station, quantum computers, swarms of drones, the Luanniao aerospace fighter, armored mech legions...
Countless black-tech weapons suddenly turn up in the deserts of the Rosha Kingdom, making Eagle Sauce deeply uncomfortable.
Eagle Sauce: These weapons came from an eight-year-old kid? I'm going to sanction that brat!
Chen Bo: This came out of nowhere. I'm only eight, and Eagle Sauce has sanctioned me.
