The fantasy story of Ding Xuanzhen, an immortal cultivator who returned after a transmigration, interpreting his cultivation abilities through modern physics theories and earning incense money through live streaming science popularization. Living in the dilapidated Qingyun Taoist Temple, he uses physical concepts such as resonance, magnetic fields, and fine-tuned gravity to explain immortal-like magical powers such as brick-splitting, water-controlling, healing, and levitation. He also gains Su Ke, a Ph.D. student from the Tsinghua Physics Department, as a disciple who uses instruments to verify his phenomena that defy common sense.
