Do All of Humanity Depend on Me? but I Only Have 100 Million Grains Left

[The end of the world + system space + hotel + contract zombies + strong women + huge golden fingers! Fifty years after the end of the world, Yun Chao was exiled by his family and disemboweled by his boyfriend because he was found to have no supernatural powers. When she opened her eyes again, she awakened the power of contracted zombies. Not only that, the storage space evolved into a planting space. Poisonous mist infected water sources, and countless people died of thirst. A bottle of bath water she took out at random sold for a sky-high price in the auction house. Everyone was caught in the outbreak of the zombie nest and the zombie panic. The zombies she trained were all SSS-level. When everyone was starving, the zombies she raised feasted on a luxurious seafood meal at the hotel. Everyone struggled, and when the poisonous mist invaded, Yun Chao's hotel was invulnerable. Bosses from the five major bases came to ask for cooperation, and the president of the chamber of commerce knelt down and begged to be taken in. She is just cultivating the land, why does it seem like all mankind depends on her to support her?
