Sign-In in the Womb: I Venture Into the Immortal Path With a System

Lin Wanxing, a top quantum physics researcher, transmigrates after a particle collider malfunctions. She unexpectedly becomes the unborn daughter of Su Qingwan, an inner disciple of the Qingyun Sect in the cultivation world, and discovers she has a twin brother. After binding to the “Daily Sign-In System of the Cultivation World,” she receives rewards on her very first day in the womb, including an incomplete innate Dao body and marrow-cleansing spiritual fluid. The System’s benefits also extend to her brother, activating a “twin-linked absorption” mode that lets them share spiritual energy and nourishment within their mother. Using a basic breathing technique, she takes her first steps on the path of cultivation while still in the womb. Her brother passively receives a boost of spiritual energy from her presence, and the resonance caused by their twin aura unexpectedly draws the attention of a white-haired elder in the Qingyun Sect’s Scripture Pavilion. With their mother Su Qingwan’s tender protection on one side and the System’s heaven-defying opportunities on the other, Lin Wanxing and her brother build up their foundations in the womb as they await the day of their birth, ready to embark together as twins on a cultivation journey filled with both danger and opportunity.
