Inside Zero's VR headset a display screen had already carried out a simulated calculation for the plan.
The TS-283 nuclear bomb is a secret strategic military weapon from "Kael Technology" a leading company within the "Mechanical Alliance."
A small TS-283 nuclear bomb can blow up a 100-meter-tall building. A medium one can wipe out nearly half a city. As for a big one—there's no official info, but Kael Technology says it can erase an island.
