I Survived Until I Became an Immortal Through Sheer Skill

In a realm of gods and demons, where monsters and ghosts roam freely, Gu Changsheng, who transmigrated to the outer sect of the Han Hai Sect, can only rely on his skill proficiency panel to cultivate immortality. In his leisure time, he fishes ([Fishing Experience +1]), draws talismans ([Talisman Dao Experience +1]), and peeks at a beautiful young Daoist nun ([Dao Heart Without Dust Experience +1]). Is this even acceptable? Gu Changsheng only wants to survive. Survive until he becomes an immortal, survive until he's invincible!
