Doomsday: My Supermarket Connects to the Heavens

The apocalypse is coming, zombies are besieging the city, and humans are fighting for half a piece of bread, but Lin Chen accidentally activates the Zhutian supermarket system - others chew bark and swallow grass roots. On his supermarket shelves, instant noodles are exchanged for cultivation world spirit rice, iodophor is mixed with fairy world healing pills, and even compressed biscuits can be used to buy Zhuge's crossbows and interstellar energy cannons from the Three Kingdoms! Zombie wave? Zhuge fired a volley of crossbows, corpses piled up into a wall; mutants raging? Exchange Xianxia Talisman and kill instantly with one click; the base is short of supplies? Connected to the planes of the heavens, food, equipment, and elite soldiers are always on call! What's even more outrageous is that the supermarket is still an absolutely safe zone. There are corpses everywhere outside, but there is enough air conditioning, WiFi, snacks and drinks inside. Lin Chen stepped on the corpse tide to stock up on goods, relied on the resources of the world to build a base, and lived from a doomsday ant to a doomsday overlord connecting all realms!
