Apocalypse: Starting As a Gun God, and They Want Me to Leave

[Complete New Worldview] + [Dual Transmigration] + [Retiring from Dormitory] + [Original Owner's Green-Haired Turtle] In a parallel world, all of humanity is deprived of sleep. Once you fall asleep, you will travel to a zombie world. Safe houses have appeared around the world. Sleeping in a safe house allows one to traverse a safe space in the apocalypse and avoid being eliminated immediately upon landing. Meanwhile, extraordinary class cards appeared in the post-apocalyptic world: Negotiator, Chopper, Climber, Drunkard... Every profession has its own set of skills. At Lin Ran's school, students are grouped by dormitory, supervise each other, reduce sleep, and help each other survive. Lin Ran was assigned to a room with Li Chutong, the school beauty. He helped Li Chutong travel through the zombie world, helping her become a [Survivor] and gain access to an attribute panel and storage space. As a result, Lin Ran was kicked out of the dormitory. Instead, Xu Ming, a rich second-generation, took his place. Upon learning of this, Lin Ran, the Green-haired Turtle, was so angry that he suffered a heart attack and died. A new Lin Ran has arrived from another time. Cold-blooded, decisive... Most importantly, he was very accurate! The school is going crazy! Lin Ran, the green-haired turtle, underwent a transformation overnight! When facing zombies, every shot is a headshot! Against a professional, a gun is faster than seven paces away! Within seven paces, there's practically no one! Facing a colossal boss, we went straight for its face and blasted it into a rain of blood! They were using a pistol, not a close-in weapon system! Lin Ran, who obtained the [Gun God] profession, was fiercely sought after by the student council. All the campus beauties want to share a dorm room with Lin Ran! Xu Ming, on the other hand, was proven to be a useless person who only knew how to exploit others. Li Chutong was terribly wronged, filled with remorse, and cried herself to sleep in the bathroom: "Lin Ran, come back quickly!!"
