In the 1980s, the protagonist Tan Dayong was a rural veterinarian. One night, the farm cow of the village bully's family was bitten by a poisonous snake and was about to die. Several sons of the village bully's family rushed to the veterinarian Tan Dayong's house and called Tan Dayong over to treat the cow. The veterinarian Tan Dayong examined the cow's wound. He told the village bully that the cow had been bitten by a poisonous snake for too long and could not be saved. After hearing this, the village bully's sons beat veterinarian Tan Dayong half to death and fainted. When he woke up, veterinarian Tan Dayong only felt a pain in his head. When he opened his eyes, he found that he had traveled through time and was in the body of a disciple of an ancient miracle doctor, who later became a miracle doctor in the world.
