In the apocalyptic world where order has collapsed, Lu Jin, a lightning powerhouse with top-notch combat power and lack of emotion, accidentally rescued Lin Ruanruan, an art student who is as timid as a mouse but possesses rare healing powers during a mission. One is extremely cold and the other is extremely cute. The two are forced to team up and embark on a journey full of dangers.
Their relationship has evolved from "trouble and burden" at the beginning to each other's only dependence and protection through life and death tests. When Lin Ruanruan's healing powers attracted the covetousness of various forces, and when Lu Jin's dusty past intertwined with the shocking conspiracy behind the apocalyptic virus - the "Pandora Project", they discovered that Lin Ruanruan was the key to unlocking all the mysteries.
In the end, on the wasteland, Lu Jin shattered the darkness with thunder, while Lin Ruanruan restored hope with the light of life. What they face together is not only the zombies all over the mountains and plains, but also the abyss of human nature and the choice of evolution. He taught her to survive, and she taught him to love, and together they defined what it means to be truly "powerful" in the end of the world.
