SSS-Rank RV Across the Apocalypse — And My Teammates Keep Getting Crazier

Seven days of black rain. 90% of humanity turned into zombies. Lin Ye awakens the SSS-Rank talent "Order Enhancement" — he can upgrade anything. While others wait to die in the rain, he turns an Armadillo heavy truck into a "Land Aircraft Carrier." Cold beauty doctor? S-Rank Holy Healing Light. Hot-tempered mechanic girl? A-Rank Mechanical Resonance. Building a Gundam by hand? Not a dream. No planes, no tanks, no fighter jets, no spaceships. Just an RV that gets more ridiculous with every upgrade, a little sister to rescue in Magic City, and a crew of female teammates welded to the vehicle. The doors are welded shut. No one's getting off.
