Demon Slayer Doctor

Liwei House Rules: 1. Money comes first. 2. No matter life, old age, sickness or death, no matter ugly or beautiful, no matter good or evil, as long as you have enough money, then please petitioners write down your demands! 3. We only recognize the demand list and only have money in our eyes. Don't crave our loyalty. This will become a sharp weapon inserted into your back, but you can try to influence us and get our approval! We will become the most powerful weapon in your hand. 4. We are neutral, we are sinful, and we are great. 5. The members in the library are each other's backs and dependence. If you hurt our reliance, then please wait for our revenge, whether it is heaven or hell. We are everywhere. 6. We welcome any friends who join us, even if it is just for one of us; we do not object to the withdrawal of members, because we know that family members will always leave and be separated, so for the sake of happiness, please be happy! A mysterious organization, a mysterious doctor, a medical consultation order from a thousand years ago without a follow-up visit, and a huge commission from a thousand years later, Yuki Taira felt as if he had fallen into a huge chaos... If a doctor came to the Uyashiki family, would misfortune still become misfortune?
