Set up a Stall to Sell at the Beginning [Set a Stall to Sell Vigorously at the Beginning]

Alien invasion: I save the world by selling books! Four hundred years ago, endless Zerg and Corpse races emerged from the "Gate of Immortality" that tore apart the Ming Dynasty, turning the prosperous age into a sea of ​​blood in purgatory. Accompanying the disaster is the revival of the earth's dormant spiritual energy. In the blood and fire, the pioneers ignited the fire of awakening, and based on the bones, they built towers of professional awakening and martial arts fortresses all over the world. Today, in the land of the Ming Kingdom, the shadows of the battlefields of all races (Zergs and Zombies) hang like sharp knives from the ceiling. The martial arts hall tempers the sharp edge, and the literary hall cultivates spiritual light, both of which are the fire for the survival of mankind. In Guan Gong Middle School, Su Qing, the top academic genius, awakened an extremely rare contract summoner profession, but only contracted one cat, making him the laughing stock of everyone. No one knows that this cat is the starting point for Su Qing to reach supreme power. This cat is the incarnation of the book selling lottery system. Every time a book is successfully sold, he can randomly draw an item or skill from it: A copy of "Selling Power at a Stall" can be exchanged for the "Power Potion" that can collapse mountains and crack rocks; A copy of "Doraemon" actually drew magical props; While the professional genius was fighting for survival on the battlefield of thousands of races, Su Qing set up a stall on the battlefield and ran his fingertips across the cover of a "Three-Body" illustration book. "Ding! Congratulations to the host for getting: two-way foil dimensionality reduction strike (one-time trial version)." The Zerg brood blocks the sky? The supreme power of the corpse clan dominates the world? Su Qing raised her eyes calmly: "Sorry, we close early today. Please... Please take a look at the painting."
