Ye Feng is framed by his fiancée, Shen Jiao, and the medicine merchant Wei Tianlong. They break his right arm and push him off Snake Cliff. Fortunately, the white deer he saved ten years ago rescues him with a Wood Spirit Pearl, regenerating his broken arm and awakening his Azure Wood Divine Eye and the power to control wood. Armed with rare medicinal herbs, he overcomes one crisis after another and foils Wei Tianlong's schemes. Ye Feng ventures deep into the Hundred Thousand Mountains, discovers the Qin family's ancestral Medicine King Cave, and raises funds by auctioning rare herbs. He establishes the Shennong Group and develops a mountain-foraging business. Shen Jiao and Wei Tianlong eventually get what they deserve and are brought to justice. Later, he ventures into an uninhabited wilderness, defeats a gang of poachers, finds his father's belongings, and uncovers the secrets behind an old mountain disaster and the Nine-Colored Divine Deer. In the end, he chooses to return the Wood Spirit Pearl to help the white deer recover and allows it to return to the mountains.
