Traveling Between Two Realms, Starting from Refining Elixirs and Becoming an Immortal

I am the first in the city in the Immortal College Entrance Examination at the age of eighteen. I am a peerless genius who is proficient in alchemy, talisman making, formations, and weapon refining. Who would have thought that at the beginning, I was just an ordinary student. What pushed me to change so much was because I could travel between two worlds!
