Synesthesia!!
This was a powerful ability derived from Yi Beidou's Celestial Demon Sensing. It allowed him to perceive the True Intent deep within objects, recreating past scenes where that True Intent lingered—an ability tantamount to a Retrospect of spacetime itself!
Yi Beidou was now using this very sensory ability, and his target was the Earth Immortal Cells within the East King's body—cells originating from Penglai Immortal Mountain.
Through his prior investigation and research on Earth Immortal Flesh and Blood, supplemented by the intelligence Beretta had provided, Yi Beidou had gained a deeper understanding of the Earth Immortal Cells.
One key point was that the Earth Immortal Cells contained remnants of their original host's True Intent, possessing a certain "conceptual" attribute. Even in cells that had undergone Refinement, the Ancient Ones could not completely erase this residue, which seemed to penetrate their very essence.
