Shen Lei's online friend of many years sent him an expensive and exquisite teenage girl figure named Wan Wan on his birthday. When his eighteenth birthday arrived, the All-Things Dimensional Elevation System bound to him, and Wan Wan awakened into a real-life young girl. She comes from another world, attracting the Dark Hunting Organization, which specializes in capturing and reselling otherworldly beings, to hunt her down. Leveraging the system to upgrade his physique and combat power skyrocketing, Shen Lei cooperates with Wan Wan, who possesses seduction abilities, to figure out the enemies' conspiracy strongpoints. The two forge a bond and embark together on the path of becoming stronger by crusading against the dark evil organization and achieving an urban counterattack and protection.
