After Returning from Exploring the Universe for Our Country, the Earth Is Going to End

My name is Lin Yue. I was reborn in a parallel world and became an astronaut. My return capsule is falling. Because of my encounter with a black hole, I traveled directly to the earth fifty years later. Moreover, I also discovered that the earth is going to end! Plants mutate and animals mutate. Only humans do not mutate. The population is only one-fifth of its former size. Cultivated land is lost. Food is in short supply. Countries have established bases to survive. The most noble profession is that of agricultural plantation officer. And I have awakened the "Shen Nong Technology System". As long as I grow crops, I can exchange them for technology. When I planted an extinct, non-mutated watermelon on a barren land, it made everyone burst into tears. Then, I started to engage in scientific research like crazy: high-value culture fluid, non-mutable potatoes, super-fertile black soil... Then, electromagnetic guns, magnetic storm tanks, Xuannv fighter planes. My goal is to first let my compatriots have enough to eat, and then regain their homeland and rebuild Daxia. And when Daxia's productivity once again reached the level before the disaster, Yingjiang on the other side was stunned. "Rabbit, I knew you didn't hold in your food well!"
