After the Cliff Fall, a Medical Hero

The protagonist saw their blind younger sibling approaching a cliff and, in an attempt to save them, fell together into a deep ravine.

The place they fell was a mysterious cave of a white snake, thousands of years old, and the humid environment of the cave allowed their body to fully recover. After the accident, an unknown and significant change occurred in the protagonist's body and intelligence.

When the village thug, Kallu, harassed the protagonist's younger sister, the protagonist subdued Kallu with their newfound powers. Seeking revenge, Kallu enlisted health department officials to pressure the protagonist to close their clinic.

The official escalated the pressure, informing the protagonist that if they didn't obtain a medical license within two months, the clinic would be sealed.

The protagonist took the medical license exam within the short two-month period given by the health department official. In the examination room, a friend trying to hinder the protagonist chose the most difficult patient, but the protagonist immediately diagnosed the patient's condition.

They accurately diagnosed a rare blood-related disease that numerous doctors had failed to identify for decades.

After passing the exam, the protagonist was chosen as a disciple by an experienced doctor, officially recognizing their outstanding medical skills.
