Doomsday: My RV Upgrades Infinitely

Lin Feng is reborn just before the outbreak of the zombie apocalypse and awakens a god-level RV system. Abandoning the family that once caused his death, he drives a Wuling Hongguang that continuously upgrades by consuming metal: evolving from an armored RV into an iron fortress, and eventually into the aerial city "Dawn Miracle." In a doomsday world alternating between extreme cold and heat, he establishes a barter market, recruits survivors, and ultimately flies away from the hellish surface of the earth. Meanwhile, his selfish family, consumed by mutual schemes and betrayal, all perish at the hands of a zombie horde.
