When Night Gray-Famale's investigation achieved a breakthrough.
As he delved into the condition known as Polick Spiritual Energy Syndrome, he found a subtle connection between "Experimental Subject A" and Fengling. According to Man Sheng Biopharmaceutical and a series of subsequent tests, they all pointed to one fact—the parts of Fengling that were called a "genetic miracle" appeared after the death of "Experimental Subject A".
Everything traced back to the fire at the prosthetic hospital of the Twin Flowers. Based on the internal investigation of Man Sheng Biopharmaceutical, they believed that a patient suffering from Polick Spiritual Energy Syndrome, in a state of mental confusion, had set the hospital afire. Consequently, they adjusted the strategy for the adaptation treatment, sedating the patient as they neared the end of life. If the patient developed a clear antibody reaction to the anesthetic, they would physically restrain the patient's movements.
