Apocalyptic Disasters: Starting with a Breakfast Shop

No CP + apocalypse + running a business + light ensemble cast Wen Yan stayed up all night to beat a game. After sleeping for a while, she woke up inside it. The System said: “Your Lucky Gift Pack has arrived. Please claim it, player Wen Yan.” Wen Yan said: “I refuse.” The System said: “Automatic claim successful.” Wen Yan: “Is this a forced sale or what?” The System fell silent, leaving Wen Yan alone to stare wide-eyed at the enormous breakfast shop and the zombies. Still bewildered, Wen Yan began rummaging through her Lucky Gift Pack. It turned out to be the very breakfast shop game she'd just beaten. Except... It was still the same game, just with a few zombies. Looking at the handful of zombies wandering around, Wen Yan: “...” Holding a piping-hot jianbing guozi that smelled irresistible, Wen Yan looked around. There were zombies everywhere! “Where am I supposed to find customers to buy breakfast in the apocalypse?!” Just then, a few muffled whines came from a dog. Wen Yan looked down and locked eyes with a dog drooling all over the place, a crystal core in its mouth. A big yellow question mark appeared above the dog's head. Wen Yan: “Fine.” And so, while ordinary people struggled to survive in the apocalypse, Wen Yan sold jianbing guozi amid the zombies. Noodles, bread, pastries, desserts, roujiamo, rice noodle rolls, grilled cold noodles, fried rice and stir-fries... Wait, why am I supposed to sell hot pot, malatang, barbecue, and roast duck too? Isn't this a breakfast shop? Who eats all that for breakfast? A horde of starving survivors: “We do! We'll eat it all!”
