Cultivation of Immortality Starts from Blood Type

Lu Yuan traveled through time. A laboratory doctor at a tertiary hospital, he woke up and became the young master of the Blood Demon Sect. His spiritual roots were rotten, his cultivation relied on pills, and he had just drunk himself to death in front of the beast's legs at the wine table. The beginning is hell difficulty. Dad was practicing blood transfusion, and his whole body was in convulsions, and he had a high fever and fell into coma. All the medical practitioners in the sect were helpless. The elders have begun discussing behind closed doors the choice of the next sect master. Lu Yuan walked into the secret room. Dad had a jade tube in his arm and a basin of soy sauce-colored urine beside the bed. "Who asked you to give him a blood transfusion?" Everyone in the room was shocked: "This is a blood exchange method. It is an ancient method passed down. What's the problem?" Lu Yuan asked Xiaohuan to get two bowls, a silver needle, and a bowl of water. He dropped the blood of his father and the donor into bowls, diluted it, and then slowly poured it together. More than twenty pairs of eyes stared at the bowl. The blood begins to clot. There are more and more tiny red particles, getting denser and denser. "That's the problem." He put down the bowl, "The blood types don't match, and the infusion is poison." From this day on, there was blood type science in the world of immortality. From this day on, Lu Yuan set an iron rule for himself. In this world, cultivating immortals also requires science.
