A Global Zombie Outbreak? I'll Just Summon the Feiying Armor

(Blood moon + human zombies + insect zombies + animal zombies + no saintly heroics + decisive and ruthless + apocalypse survival + one female lead + invincible!) The blood moon hung overhead, and the sky split open. The zombie hordes surged, and the world fell. Civilization collapsed, and order vanished. While everyone else fled in despair, Lin Xiangfei calmly pressed the summoner: "Shadow Armor, combine!" A gust of wind, a flash of blue light tearing through the sky! One man, one suit of armor, carving a path through a mountain of corpses and a sea of blood! From ruined cities to irradiated wastelands. "Too weak." He crushed the head of a giant mutant spider queen beneath his foot. His blade swept through the air, and the spider horde exploded in an instant! From packs of mutant beasts to nests of alien species. "That's it?" He stood atop the corpse of the Breach Zombie King, killing intent filling the air, surrounded by tens of thousands of dismembered bodies! From military encirclement to military bases. "You think you're worthy?" He crushed the neck of the so-called "Apocalypse War God" in his exoskeleton armor, then struck back with a single slash that split the entire military base apart! Until one day, a crimson rift opened in the sky. Otherworldly behemoths that blotted out the sun descended, and humanity fell into utter despair. But the corner of Lin Xiangfei's mouth curled into a smile. "Finally... I can take this a little seriously."
