I’ll Grind My Proficiency Until I Become an Immortal

In this strange and eerie realm, demons and monsters roam, and ghosts run rampant. After transmigrating to the outer sect of Hanhai Sect, Gu Changsheng can only rely on a proficiency panel to cultivate immortality. Fishing in his spare time: [Fishing • Experience +1]. Doodling talismans to kill time: [The Way of Talismans • Experience +1] [A Spotless Dao Heart • Experience +1]. Wait, this actually works? Gu Changsheng just wants to keep his head down. He'll lie low until he becomes an immortal, lie low until he becomes invincible!
