Yongjishitang

He is a doctor at Yongji Shitang. He only charges a small profit for medical treatment. He often refuses to accept any money from poor people. He is a famous "living Bodhisattva" in the city. He has a secret technique that is unknown to everyone - but this secret technique has never been used because he has been waiting for someone. And she is a fox demon who kills people without blinking an eye. He has no gender, is cold-blooded, and accepts rewards for doing things. The rules have been set for three hundred years: he does three things for people every time, and he charges three thousand coins, and he does not bully others. But such a frightening existence is so poor that she can't even afford to eat - because prices have increased hundreds of times in the past three hundred years, and her prices have never changed. Their first encounter was over a steamed bun. She was so hungry that she stole one. As soon as she took a bite, she was chased and beaten. She ran away in a panic, but accidentally dropped the steamed bun on the street. The next second, a passing doctor stepped on him. She looked at the pie crust on the ground, and her eyes were red after being hungry for three days. And the gentle man raised his head and saw a murderous, green-eyed, hungry... Fox demon. He was stunned for a moment, and then smiled slightly: "Girl, do you want to come to my hall and have a bowl of noodles?" ——He didn't know that this bowl of noodles was repaying a debt from three hundred years ago.
