Xiao Xia, who was betrayed by relatives and lovers in her previous life and pushed into the corpse tide, was reborn one month before the end of the world with endless hatred. She quickly cashed out tens of billions of dollars to hoard supplies, activated the Sumeru Space and Shadow Devouring powers, and vowed to make her hypocritical enemies pay the price. As the apocalypse approaches and extreme climates rage alternately, she begs for help from her enemies. In the ruins, she meets and forms an alliance with the mentally out-of-control "Crazy Boss" He Lin. The two are both lone brave men in the darkness. They use "Lone Brave Man" as their war song and password to save each other in the crisis of extreme cold and mutation. They sneaked into the survivor base controlled by the enemy, and in the final showdown of the beast siege, they tore apart the mask of "light" and pushed the betrayers into the abyss of despair. In the end, these two apocalyptic two wolves did not want to gain power, so they sailed to the wasteland hand in hand, proving with their actions: "Who said that only those who stand in the light are heroes?"
