Slaying the Apocalypse with a Game System

(Apocalypse + Time Travel + Cheat Skill + Pet + Early Support, Later Invincible + Has CP + Fantasy Elements) Yu Yao, who was physically disabled, traveled to another world with the game system she had played for three years. She transmigrated into Yu Yao, an orphan who had just lost her last remaining relative. An orphan turning into another orphan, not a big deal. The problem is, the world she just arrived in is less than two months away from entering the apocalypse. Zombies run rampant, mutated plants and animals take over, order collapses, and the world is in ruins. …… So thrilling—of course she has to bring her cheat skill, grip her dual blades tightly, kill the fiercest zombies in the apocalypse, loot the best gear, and live the flashiest, most unrestrained life. Hmm? Boyfriend? Of course she has to date the most handsome one.
