Urban martial arts, urban imagination, no suspenseful and supernatural elements Superpowers + single female protagonist + no golden fingers + the combat power system will not collapse + the villain is not brainless and the protagonist is not invincible. Warning in advance: since it is not a brainless novel, the previous chapters may seem unclear when setting up the foreshadowing. Please feel free to read.
