Slave and Mistress

You come to ancient Persia two thousand years ago, the era of slavery. You have special powers. Whether it is a serious injury or a chronic disease, you can heal the injury or illness with just one touch. You controlled your powers in a low-key manner, and quickly established yourself as a famous doctor here, earning you great respect. You bought a slave. You find that no matter how you treat him, he is loyal to you. You have just whipped him, but he is going to die for you. You don't understand how such a person could exist. He is obviously gentle and strong, and he has received the freedom you gave him, but instead he kneels at your feet in fear. * The hero's loyal dog. Although it is said to be ancient Persia, it is actually purely fictional. Purpose: Liberate oppressed groups.
