Can I, a doctor, save 10 billion lives in another world?

As a physician, could I rescue ten billion souls in a different realm? Driven by the desire to heal everyone, I practiced medicine in a broken system. After an untimely demise, I awoke reborn as Prince Eiji. In this land dominated by blind faith, where countless perish without proper care, I wielded my past expertise—performing operations and crafting tools to defy superstition.

What truly preserves life: divine intervention or science? Armed with millennia of medical wisdom, I’ll challenge both deities and illness. No deity will stand between me and those I vow to save.
