Blackened Divine Doctor, Starting From a Veterinarian Towards the Pinnacle of Life

Gu Ming, a talented veterinarian, suddenly obtained the Divine Doctor system. Before he could even enjoy the glory, he was sued by a group of ungrateful people and was sentenced to a lifetime ban from practicing medicine. In a fit of rage, he decided to 'return' the illnesses that should have belonged to those ungrateful people. Ungrateful person number one: 'Divine Doctor Gu, please save my life!' Ungrateful person number two: 'Oh, Divine Doctor Gu, please forgive my small mistake...' Ex-girlfriend knelt and cried: 'Waa, Gu Ming, I was wrong! I have 'Love-to-Death' disease, please save me!' Gu Ming replied: 'I'm sorry, everyone, I'm just a veterinarian, I only treat animals... (birds and beasts)'
