Nano Trilogy III

Creation of an unprecedentedly grim nanoscale molecular apparatus for collective deployment; conceived in clandestine corporate labs by ruthless engineers and shadow financiers, its oversight was deliberately eliminated and records erased, the device proves immensely potent and nearly uncontrollable; this offensive technology devastates multiple hamlets and slaughters hundreds; the youths, now mature specialists, establish their own molecular counterweapon initiative; engagements in African settlements now feature American advanced military gear, including bespoke molecular neutralizers, US micro-drones, witchcraft botanicals and trained venomous serpents, which together secure decisive wins for the musketeers; the industrial mastermind, called Korrectorizer, is followed from New York to Washington, D.C., to the Caribbean and across Europe; he is cornered by the musketeer squad; they discover he murdered their fathers; vengeance begins; nevertheless, no corpse was ever recovered.
