Song Bing, a veterinary student, was falsely accused of practicing medicine for free. He was accidentally bound to the medical delivery system, which can absorb or transfer diseases. He refuses to compromise, and while running a veterinary clinic to accumulate merit, he uses the system to fight back against false accusers and villains, and heal those who are trapped. Along the way, he received help from Siya and others, uncovered multiple conspiracies, and counterattacked with his medical skills and wisdom. He not only cleared his grievances, but also gained career and true love, and lived a wonderful life.
