Bulgarian Metro: The Root System

Martin Von Hael, an ordinary high school student, awakens in a nightmare: the post-apocalyptic Bulgarian Metro. Radiation scourged the surface decades ago, leaving a labyrinth of dark tunnels where mutated horrors lurk and human factions ruthlessly guard their stations. Martin, now armed with the unique "Tree Skill System" — a burgeoning power allowing him to develop physical, mechanical, or metaphysical abilities — must navigate this brutal new reality. Every station is a potential trap, every face a potential enemy. Will he pledge allegiance to a subway lord, daring to survive another day in the suffocating depths, or will he risk the mutant-infested surface, driven by a primal urge to understand the truth of his reincarnation? He carries the deep chill of his past life’s abrupt end, making him outwardly cold and ruthlessly pragmatic. Yet, to truly live, Martin must confront not only the monsters of the world but the icy fortress around his own heart. The choice will define his fate and potentially that of the last vestiges of humanity.
