I recommend "Primordial: Hiding for a Thousand Years, Coming Out to Shock the Heavens","Immortal Immortality, Starting from Farming Emotions","Absorbing Emotions to Become Stronger","One Piece's Emotional System","Data Transformation Otherworld","The Great God Attacks: Crazy Pastry Master","Spare My King's Mercy, I Can Collect Positive Emotional Value","I Can Control Personalities","Infinite Enlightenment", and "Master of Authority". They all had plots that used emotions as the core to cultivate or gain advantages. I hope you like this fairy's recommendation. Muah ~😗
