A Nuclear Submarine as a Superweapon? I’m Using It for Global Deliveries Instead

[Urban Imaginative Fiction] [Global Shipping] [Ghost Captain] Poor security guard Shen Qian unexpectedly gets a 60,000-ton nuclear submarine from a parallel world. He thinks he's about to reach the pinnacle of life, only to spend the next three hours listening to the submarine's control AI explain the rules. Shen Qian: “If this isn't allowed and that isn't permitted, what am I supposed to do with this submarine?” “Observe marine life?” “Volunteer as an underwater cleaner?” Luckily, a twist of fate helps him find his calling: global shipping. Nuclear power means zero fuel costs; underwater speeds start at 50 knots... He'll ship what others dare not transport, and sail into waters no one else can reach! From hauling boxes and doing manual labor to owning private docks across several continents; by day, a security guard who got rich overnight, by night, the world's most mysterious Ghost Captain. Until one day, someone contacts him: Bring back a few people. There's no shipping fee, but we can give you a plaque, the kind you hang by your front door... Shen Qian: “No problem.” “For shipping, call ‘Save Money’: fast and safe!”
