Gu Yi, from a family of medical immortals, is talented but obsessed with swordsmanship. He was originally the person who was most likely to break through the void and become a "Sword Immortal" in the ancient moon continent's sword sect for thousands of years. However, he was plotted by his fellow sect and betrayed by his lover. Although he narrowly escaped death, his meridians were blocked. At this point, his temperament changed drastically, his game world, and his cultivation also plummeted. Later, he lost his friend Ling Chengbu. He never gave up, specialized in medicine, and opened the ruins of the world. By chance, he got the Heavenly Spirit Pill, but his spiritual veins were restored but he had erysipelas. He had no choice but to choose to practice both medicine and poison. After many life and death, he was ascending, which happened to be the birth of the blood demon, and thousands of demons were plundering him. Out of pity for the creatures in the world, Gu Yi used his body as a shield and his flesh and blood as an array to suppress the blood demon at Jueming Peak.
