Ling Xuan, a medical immortal, spent his life hanging a pot to help the world, but because he was unwilling to hand over the Immortal Sutra of Medical Dao, he was hunted by traitors and died on the top of Zixia Mountain. When he opened his eyes again, his soul returned to modern times and possessed the body of Wang Yi, an eighteen-year-old farm boy. The family is poor, the grandmother is seriously ill, and she is even more frail and has a broken Dantian - the medical fairy who once dominated the world of immortality has become a poor boy who cannot afford to eat three meals a day.
However, medical skills are immortal and Taoism has not changed. Relying on his thousands of years of medical heritage and immortality cultivation, Wang Yi survives in desperate situations: he first tries silver needles to relieve his old ailments, searches for medicine in the mountains to trigger Qi training methods, cures ailments in his neighborhood and accumulates reputation, outsmarts village tyrants, and cleverly defeats the tricks of profiteers to gain a foothold.
From farmhouses to county drug stores, from free clinics in villages and towns to sit-in clinics in provincial capitals, from county-level seminars to national medical conferences, he used his extraordinary medical skills to solve difficult and complicated diseases, and used ancient prescriptions and new applications to promote the innovation of traditional Chinese medicine. Qi training, foundation building, elixir formation, Nascent Soul... He embarked on the path of cultivating immortality in the modern world, condensed his cultivation in practicing medicine, and explored opportunities in adventures: ancient medical scrolls in ancient caves in deep mountains, cultivation secrets in underwater ruins, ancient medicinal herbs in primeval forests, and holy cultivation sites in secrets in snowy mountains.
From his humble beginnings as a farmer to the world of medicine, from deep cultivation to Yuanying, from adventures on the earth to exploration of the universe, Wang Yi entered Taoism through medicine and demonstrated medicine through Taoism. During his journey to the modern world, the fairy world, and the Hongmeng world, he wrote a legend of "medicine can revive the dead, and medicine can regenerate bones." Finally, he became the supreme leader in medicine, and let the glory of medicine shine in the heavens.
