The Whole Network Is Running for Their Lives, but I Am Planting Flowers with Nasida

[This is really my first time learning to write a novel. I know that I have many shortcomings and shortcomings. I feel that it has become a chronicle. The book has been scrapped. I can't read it anymore. I have restarted it.] The end of the world is coming, zombies are surging, and the world is in despair and fleeing. Shen Ne awakened the [Wish System] - but the first task was not to kill zombies or find supplies, but: "Ask the host to summon a favorite virtual character to become an exclusive guardian spirit." He looked at the screen full of Genshin Impact characters and chose Nasida without hesitation. Then, something magical happened. The dead trees sprouted on the land where Nacida's fingertips touched, and the poisonous fog dissipated. Wherever she walked, the zombies were stunned for a moment, and then walked around silently. Shen Ne's system is not idle either: daily mission rewards are seeds, watering and "mobile base expansion module". A palm-sized grass slime stood sentinel for him, raising a winged herbaceous mushroom that evolved into a purifying spore-spraying mushroom. The ultimate giant emerald-feathered terror mushroom at the bottom of the box flapped its wings, and spore feather blades fell from the sky, turning the entire tide of corpses into spring mud fertilizer on the spot. Others were desperately trying to grab a can in the ruins. Shen Naque and Nasida planted flowers on the roof of the building, settled in the car, and listened to her talk about plant philosophy while basking in the sun. Occasionally, zombies pass by, take a look, and then leave again. Later, distress signals were sent from various survivor bases. Shen Ne was squatting in front of the flowerbed of the mobile base watering the flowers without raising his head: "Don't worry, wait until I finish watering the roses - Nasida said that when the flowers bloom, hope will come." The end of the world doesn't need heroes. All you need is a reliable system, a warm grass god, and a mobile home.
