This is the legendary story of how an ordinary young man, Lin Yu, rises to success in the city through his passion and dedication to traditional Chinese medicine, advancing its preservation and development.
Orphaned at a young age, Lin Yu becomes an apprentice at a small clinic, where he studies medicine under the old doctor, Grandpa Li. After successfully treating a rare illness, he helps bring the clinic into the spotlight, but also attracts the jealousy of his peers. With the help of Su Zhengguo, chairman of a pharmaceutical group, Lin Yu gets the chance to take part in a traditional Chinese medicine research project. Overcoming one obstacle after another, he develops a new Chinese medicine formulation and earns widespread acclaim, only to be maliciously smeared by a rival. Through his intelligence and hard work, Lin Yu overcomes the crisis and helps the traditional Chinese medicine hospital grow.
As his influence expands, the foreign pharmaceutical giant Pfizercon secretly schemes against him. Drawing on his expertise and unwavering convictions, Lin Yu makes a comeback and wins back his reputation, while also helping traditional Chinese medicine reach the world. Invited to join a World Health Organization project on traditional medicine, he works with experts from around the globe, overcoming differences in approach and other challenges to achieve major breakthroughs. When efforts to promote the results face interference, Lin Yu stays true to his original purpose and responds proactively. He also remains committed to passing on traditional Chinese medicine, planning to establish an international research and educational institution to breathe new life into its development.
