The day the zombies broke out, Gu Suan was selling cars at an auto show. A thousand people surged toward the exits, but he snatched the AI smart car on display and floored it, blasting through the crowd. While everyone else scrambled for supplies, weapons, and territory, he did just one thing: calculate. He calculated the zombies’ rules of perception, the warnings left unclear in the announcements, and who would land the final blow when the cards were dealt. Nobody believed a car salesman could survive three days. Until a horde surrounded his convoy and he called out three escape routes through the car window, each one spot-on. While everyone else was running for their lives, he was clearing the level. The Earth was purging itself, the zombies were evolving, and the climate was spiraling out of control. Gu Suan calculated one step ahead in everything, always weighing the costs and gains.
