The name of Hua Tuo and Zero's rustic temporary clinic was simple. Since they were giving free treatments, they named it Hope Clinic for the poor who couldn't afford proper medical treatment. Hope Clinic didn't discriminate between species when it came to treatment. The house rule was simple. They only asked the patient to pay what they could and did what they could to help.
Mammon sponsored the cost of medicine although most of the medicinal plants came from either Hua Tuo's private garden or Half Moon Village's herb garden. Zero managed to borrow a plot of land from Beelzebub to start planting the common herbs he needed.
