On the day when the zombies broke out, Gu Suan was selling cars at a car show. Thousands of people crowded towards the door. He grabbed the AI smart car at the booth with his backhand, stepped on the accelerator and rushed out of the encirclement. While others were grabbing supplies, weapons, and territory, he only did one thing—settling. Count on the zombie perception rules, the early warnings that were not clearly stated in the announcement, and the final blow of the card distribution. People believe that a car seller can live for more than three days. Until the zombies surrounded the convoy, he reported three escape routes through the car window, exactly. While others are running for their lives, he is clearing the border. The earth is purifying itself, zombies are evolving, and the climate is getting out of control. Calculate, calculate one step at a time in everything, and calculate the gains and losses.
