Young veterinarian Gu Ye is set up by his ex-girlfriend and creditors and takes over a dilapidated pet hospital burdened with 800,000 yuan in debt and medical malpractice disputes. At his lowest point, he binds himself to the Divine Pet Doctor System, gaining access to top-tier diagnostic and treatment abilities. However, because the system enforces standardized pricing, online rumors falsely label his clinic an outrageously expensive scam, while competitors try to suppress him. Staying true to his calling as a doctor, Gu Ye uses his exceptional skills to cure numerous critically ill pets and gradually rebuild his reputation. When the corporate giant Pet Care Group launches a capital-driven siege against him, he rises to the challenge, builds a medical alliance, introduces affordable pet health insurance, establishes a rescue center for stray animals, and participates in setting industry standards. His small clinic grows into an industry benchmark, and he ultimately becomes a legendary veterinarian!
