In the early days of the Republic of China, warlords were fighting each other, and the various forces were divided, making the people miserable. At the same time, Japanese invaders secretly penetrated in an attempt to plunder China's resources and treasures. In such an environment, the Miao family, as a traditional Chinese medicine family that has been passed down for hundreds of years, adheres to the ancestral motto of helping the world and saving people, and is highly respected in the local area. However, its profound heritage and precious prescriptions have attracted covetation from all parties. The head of the Miao family suffered a heart attack due to internal strife at home and was replaced by a new official from the underworld due to a work error. His soul was changed into a native dog. The soul of Mr. Miao, who had passed through the native dog, teamed up with the native dog owner Jiu'er and the second young master of the Miao family to defeat the evil family, protect the Millennium Pharmacy, fight against the Japanese invaders and attack the warlords, and support the new China.
