Panacea

Gu Changan traveled to the world of cultivating immortals. He cultivated to the Nascent Soul in his first life but died, and was reincarnated successfully in his second life with his memories. Due to his poor spiritual roots, Gu Changan chose to practice the "Ten Thousand Medicines of Immortality", a technique that does not rely on qualifications. He can directly swallow and refine thousands of elixirs. If he completes the practice in each realm, he will gain double life span. Adhering to the principles of sound management and careful fighting, Gu Changan collected herbs and farmed everywhere, made breakthroughs in spiritual practice, lived for a long time in the world of immortality, met various people along the way, and eventually became a living fossil-level figure in the world of immortality, gained insight into the secrets of immortality, and became an immortal.
