The Three Realms Pharmacopoeia records: The ancestor of all medicines was born in chaos, and eating it can lead to eternal life. Luo Jingchen, the most gentle and gentle disciple of the Medicine King Valley, went into the forbidden area to search for medicine in order to save his dying master, and unexpectedly uncovered a shocking secret - it turned out that his master was the real culprit who massacred the whole family of the Medicine Clan, and he was actually an orphan of the Medicine Clan. In order to take revenge, he disguised himself as a hypocritical medical fairy, used medicinal food as bait, and set up a shocking chess game in the world of cultivation. Every night when the moon is full, a strong man will die suddenly due to "medicine diet", and his death will be like the "medicine disaster" recorded in ancient books. When the last enemy fell in front of him, Luo Jingchen discovered that he had already become a more terrifying demon than his enemy in his revenge. And the real "ancestor of all medicines" was awakening in his body at this moment.
