Alien Beast Girl? My Talent Is Actually My Ex-Girlfriend's Picture Book

I, Lu Yuan, have awakened in the era of global mutation. However, while others were awakening fire and frost and becoming heroes to protect the city, my talent was officially identified as "the most useless in history" - I myself could not fight, nor could I absorb any energy, so I could fight against the five scum alone. My talent called [Transformation of Emotional Imprints] also has another "surprise": the resentment, unwillingness and love of my ex-girlfriends who were let down by me in those years can actually be activated by me, turning them into "exotic beast girls" who are lively and powerful! From then on, my world was turned upside down. While others fight monsters to level up, I conquer my ex-girlfriend's "Copy of Scumbag's Heart Tribulation"; while others rely on karma crystallization to drive their talents, I rely on "Regrets of Scumbag" to feed my family's increasingly picky ancestors. In order to earn their fixed weekly "living expenses", I had to wander between exes one after another, opening up new "emotional debts"... The price is that there are more and more "ex-girlfriends and beast mothers" around me who need to support me! When the cold succubus, the violent warrior queen, the ascetic actuary... They were jealous of each other for the unique "ration", and even forced me to attack the next "sister", I realized that the most dangerous dungeon in the world is not the monster's lair, but the Shura field of my ex-girlfriend. Succubus (licking her lips): "Master, the energy is not enough. It's time to activate that school girl?" Now the question is, faced with a room full of gorgeous beast-girls transformed by my ex-girlfriends, how should I explain all this to my current girlfriend who hasn't broken up yet?
