Su Qingyi, a modern gold medal veterinarian, suddenly became a hapless guy in the border military camp who was about to be beheaded for "doctoring to death" the general's favorite horse. The beginning is hell mode, there are no antibiotics, no X-ray machines, and even the most basic disinfectant alcohol is a luxury. Facing a group of ancient rough guys who have "horse disease relies on jumping skills" engraved into their DNA, Su Qingyi said: It's so difficult for me, but my professional ethics don't allow me to give up! The general's BMW was restless and anxious, he was on hunger strike and dying, and the military doctors were helpless. Everyone: "This is an evil spirit, and we must kill it to eliminate future troubles!" Su Qingyi pushed aside the crowd and calmly diagnosed: "It's not an evil spirit, it's acute gastroenteritis complicated by laminitis. Give me spirits, salt water, and a knife that is as sharp as iron. Leave the horse and the human head." At first, the soldiers in the military camp scorned this thin "young" doctor. "What does a yellow-haired boy know about war horses?" "You are pretending to be a liar!" Later - "Doctor Su! My Hei Feng has been a little depressed recently. Is he lovesick?" "Doctor Su! Take a look at my horse. It ran two extra laps in training today. Is his leg cramped?" Even General Huo, known as the "Living King of Hell", would quietly hold an injured military dog late at night and knock on her door awkwardly: "Ahem, it... Accidentally sprained its foot." Su Qingyi originally wanted to rely on her professional skills to make a living in troubled times, but unexpectedly, she accidentally became the regimental pet and the talisman of the entire army. When enemy troops attack, her secret of disguising herself as a man is shaken.
