Frozen Apocalypse: Awakening Superpowers

[Survival in the apocalypse + space ability + decisive and ruthless + alien invasion] It all began when aliens who traded in star cores learned that a source star core, over a million years old, existed in the Super Blue Star Cluster. They launched a massive invasion of the cluster. Fortunately, the guardians of the Super Blue Star Cluster intercepted most of the alien warships. But a small force of aliens slipped onto Blue Star, leaving every nation on the planet powerless to respond. With no other choice, the United Nations proposed detonating the Yin Star to thwart the full-scale alien invasion and force Blue Star out of its original orbit. Thus began a brief ice age. The protagonist's sister and brother-in-law knocked him unconscious and threw him into a river, all for a little over a million in relocation compensation. Not only that, they plotted to kill their own father, the only parent they had left, and seize his fortune. After someone rescued the protagonist, he unexpectedly awakened an ability. From then on, with no ties holding him back, he became utterly ruthless. He waged a series of battles against alien civilizations, ultimately returning Blue Star to its original orbit and successfully wiping out every alien creature that had invaded the Super Blue Star Cluster.
