Introduction: In the realm of contemporary ancient martial arts, a seemingly unremarkable female university student named Xianyu possesses the seemingly useless skills of her family's cultivation techniques. By a twist of fate, she finds herself transported into the world of the popular novel Douluo Dalu, where she discovers that she is none other than Tang San's younger sister, Tang Ning. From the outset, her identity as the beloved sister of the male protagonist foreshadows her path as the cherished darling of the group. However, Tang Ning could never have anticipated that she would encounter the male lead of another world, the Emperor Yan of Battle Through the Heavens, Xiao Yan. Most intriguingly, her true intention is simply to cling to a golden thigh for support.
