The Impossibly Perfect Gun.

You just invented The A.P.E.X.-Lance Mark III "Acheron", the ultimate mathematical limit of ballistics. It compresses a planet-cracking kinetic engine into a 36-inch, 9.2-pound carbon-nanotube bullpup chassis optimized perfectly for an average human operator. Standing as the absolute zenith of Newtonian engineering, it operates entirely within the boundaries of real-world physics while completely conquering them. The Acheron achieves perfection by abandoning chemical propulsion for nuclear energy, transitioning its firing sequence into a dual-phase atomic event. The chamber utilizes an injection of Muon-Catalyzed Deuterium-Tritium fuel. Triggered by a laser array, this fuel undergoes a localized fusion pulse, yielding 10,000 times the gas expansion velocity of any chemical propellant. As the projectile enters the bore, high-intensity terawatt super-capacitors dump electricity into the vacuum-evacuated tube, transforming residual gases into a hyper-focused plasma wedge behind the bullet. This massless plasma piston prevents pressure drop across the short 36-inch barrel, accelerating the projectile exponentially to a relativistic terminal velocity of Mach 175 (60,000 m/s), or 20% the speed of light. To handle the shattering recoil, a closed-loop Magnetohydrodynamic system pumps a liquid mercury-gallium fluid in a reverse helical track inside the stock at relativistic speeds, matching the bullet's momentum vector to reduce the felt kick to absolute zero. The ammunition consists of 30mm athermalized hafnium-isomer needles encased in a bound strange-quark-matter shell. This material possesses a near-infinite melting point, preventing the bullet from vaporizing in the atmosphere. Instead, it rides inside a self-generated envelope of cold, vacuum-isolated shockwaves. The damage output is catastrophic. Because the projectile moves at relativistic speeds, impact triggers Subatomic Nuclear Spallation, forcing target atoms to undergo nuclear fission, creating a multi-kiloton atomic blast. You have a super power, naturally your body is stronger tougher and faster but most importantly, you LITERALLY cant miss with anything ever, be it gun or bow or throwing weapons, if you in your mind wish to hit something, you will. Other heroes and even villains exist and are expected, cybernetics are a huge part of human life as well, super or not. Both Inner-self and Auto-Cards are automatically on and Auto-Cards have custom settings designed more for premium users than free users, A.K.A longer context length of 1000, the soft limit for story cards. They also do not use the standard bulletin format and instead use paragraphs. Please comment any updates you might want or bug fixes that are needed, i will happily take the time to add/fix whatever is needed, enjoy yall! :D
