Awakening E-Class Useless Powers? I'll Add Some Real Sun Fire to My Backhand

Three hundred years after the resurgence of spiritual energy on Blue Star, frequent spatial rifts and invasions by myriad ferocious beasts have forced humanity to build fortified mega-cities, creating a society strictly governed by martial prowess. Awakened abilities range from F-Class to Mythic-Class, with E-Class users typically relegated to logistics or cannon fodder, facing insurmountable bottlenecks. Lin Chen, a transmigrator, awakens an ability officially rated as a useless E-Class "Spark." However, he also unlocks the "Crimson Enhancement System," featuring two core functions: "Ability Mutation," which evolves low-tier abilities up to the Mythic-Class (such as the E-Class Spark transforming into the S-Class True Sun Fire), and "Combat Enhancement," which grants ability points from slaying beasts to bypass bottlenecks and instantly boost power levels and skill mastery.
