One month before the meteorite impact, I inherited a dilapidated zoo left behind by my grandfather, but little did I know things were far from simple. Timed impact text messages, a group of animals inside hibernation chambers, three tons of mineral water ordered a year ago—every single one was grandfather reminding me that the apocalypse is truly coming. I originally thought it was a ruined start, but who would have thought these animals would actually mutate! A fire-breathing Northeast tiger, a somnolent lizard with extremely strong defense, a parrot flexibly scouting routes, a golden python coiled into a DNA chain-like shape, the amphibian ark is ready, master, I will take you to roam wild.
