Refining immortal medicine was called the World-creating Cauldron in ancient times. In ancient times, Shennong tasted hundreds of herbs for the common people and laid the foundation of medicine for future generations. The ancient cauldron that Shennong used to refine hundreds of medicines has accumulated the energy of countless elixirs for thousands of years. It is said that it can refine unparalleled magical elixirs that even the gods in heaven cannot easily obtain, and it can also hide other mysterious powers.
