The 28th-century interstellar female killing god Jian Ke transmigrated into a doomsday novel, becoming cannon fodder whose golden finger was snatched at the start and who was killed off. Having seen countless Zerg before time-traveling, she was completely unfazed, carrying a big saber to specifically chop zombies; doomsday land cannot grow crops, so she used a bottle of purification potion to make grain grow taller than people; ordinary people have no human rights in the doomsday, and women can only cling to the strong? She deliberately teaches them to wield big sabers, one is stronger than six. In the end, she builds a new era utopia, guarding the last piece of pure land for humanity. The male lead Si Yan is reborn, in his past life his teammates all died and he himself was plotted against and died miserably, wanting to stifle the danger in the cradle, only to be stunned to find his enemy had already died long ago.
