I'm Really Not an Immortal

"I shouldn't have ever saved you and brought you up this mountain!" My teacher scolded me for ruining his precious ingredients to make the divine medicine, but later was surprised at the outcome, that I successfully made it out! I am an orphan, study divine skilled with my teacher, and now come down the mountain to gain experiences. On the first day, I meet a girl, and saved her fatehr's life. Little did I know, they are my lost family, and little did they know, I'm a powerful figure with strong ability!
