Hard to Kill: The Marksman Who Stacked Health (LitRPG, Regression, OP MC)

Ryan Slate died in the blue flames of the Westport disaster, betrayed by a squad mate during the final evacuation. But instead of the afterlife, he wakes up five years in the past, exactly twenty-seven minutes before the official launch of the Blackfall Protocol. While the rest of the world rushes to the public training halls to link with the Arcane Grid, Ryan breaks into a decommissioned maintenance zone. He isn't looking for fame or standard classes. He is looking for B-17-a scrapped calibration pod that still holds the data for a hidden class the authorities deleted from the retail version: the Runemarksman. Equipped with his future knowledge and the unique talent Hard to Kill, Ryan discovers that every surgical strike he lands permanently increases his maximum health. While others focus on glass-cannon builds and flashy spells, Ryan becomes an unkillable marksman who can dismantle spell circuits with a single shot. From reclaiming forgotten backup circuits to exposing the corruption of the CitySec Directorate, Ryan must grow strong enough to prevent the Westport collapse. The elites want to bury the truth under layers of encrypted Ward Grids, but Ryan is coming to break the code. He was a survivor once; now, he is the glitch in their perfect system.
