Volcanoes scorch the continents, tsunamis swallow city-states, and when even peak technology cannot save a collapsing Earth, humanity's final migration plan, "Xuanqiong," is officially launched. Tens of thousands of pioneers are transported to a strange new world, and everyone awakens a system from the start. Some unlock a martial arts system. Some unlock a beast-taming system. Some unlock an artifact-refining system. Then it is Luo Tian's turn, and a crisp ding echoes in his mind: "Congratulations, host, on binding the [God-tier Planting System]!" Luo Tian is stunned on the spot: "What the hell? Other people transmigrate to cultivate martial arts and become saints, and I transmigrate here to farm?" While others fight desperately in secret realms for spirit herbs, he waters cucumbers in his own plot and hums a song; while others go into seclusion and cultivate hard to break through bottlenecks, he squats on a field ridge wondering whether his watermelons are ripe; while others shed blood over a Foundation Establishment Pill, he casually hands over a tomato: "Try it, stronger than any pill." Then comes the day the beast tide breaks the city. As everyone is routed across the board, they watch Luo Tian pull a radish from the ground and toss it out.
