The Disciple's Secret Transformation

Qin Fan, an unassuming disciple of the Shangdi sect, had it all figured out - he would marry the sect's revered Saintess and live a life of ease and luxury. However, his fiancée suddenly called off the engagement, leaving Qin Fan bewildered. Undeterred, he decided to focus on his alchemy skills, using the waste materials from the sect's alchemy room to refine his own spiritual power. Three years later, Qin Fan achieved immortality without anyone noticing his remarkable progress.
