Nineteen-year-old Lin Ye has D-rank talent. His parents sacrificed themselves on the alien battlefield, and he depended on his grandfather for mutual survival. On the night the aliens besieged the city, he fell while protecting his grandfather. Opening his eyes again, he had returned to thirty days ago. The "Counter-Fate System" was activated, slaying aliens to acquire fate sources, exchanging for soul armaments, and breaking through talent limits. The C-rank that he couldn't beg for even while kneeling in his previous life is just the starting point in this life. He slays D-ranks, breaks C-ranks; slays mutant aliens, breaks B-ranks; breaks A-ranks, slays peak A-rankers. In the final decisive battle, with an A-rank body, he burned out his fate source and struck down the peak S-rank alien leader, guarding Xinjin, humanity's last stronghold. Blade by blade, he carved out a path to defy fate and change his destiny.
