[No cp, management, female counterattack, group favorite, infrastructure] Gu Xiyan, a billionaire rich woman, passed through the book and became a cannon fodder female supporting character in a post-apocalyptic novel. However, she was not afraid. She was bound to a system with its own space. She thought the system would lead her to torture zombies with sparks and lightning. However, she did not expect that at the beginning, she was asked to catch zombies and cook. Gu Xiyan said that even as a pervert, she thought this was very perverted. Later, the system painted a pie for her, saying that if she could open a food city in the end of the world and collect enough human happiness points, she could return to the real world and continue to be a rich woman. She agreed, and began to work hard to earn happiness points to upgrade her small food truck. She worked step by step, defeated monsters, upgraded and built the food city, and reached the pinnacle of life! But as she went further, Gu Xiyan felt that something was wrong. The food city was built, and there were more and more people there. But why did people stay here and treat her place as a refuge? That won't work, the price must be doubled!
