The Difficulty of This Doomsday Is Too High

Survival, development, evolution, wandering, survival! Four stars transit the sun, and the Zerg invades. The world is full of alien bugs wielding sharp claws and harvesting life wantonly. How to obtain food, water, medicine, and escape the brutal hunting of insects... Becomes a necessary test that determines your life or death. Fortunately, there is no way out, and I have read all kinds of doomsday survival novels for a long time, so I got the "Daily Settlement" system. "If this were the zombie apocalypse, I would be saving the world easily." "It's a pity that this is a Zerg invasion. Even though I have a system, I have to lower my already lowered head by three points." . This is a story about a rational protagonist who makes adequate action plans to survive in the doomsday.
