The Good-for-Nothing Skeleton Becomes Invincible After the Campus Beauty Summons Him

My name is Su Yuan. I was an elite mercenary. After dying, I became a tiny, talentless skeleton spirit pet. By chance, a cool, aloof campus beauty summoned me and made me her spirit pet! Everyone calls me a useless skeleton, but no one knows I have an Infinite Plunder System! Kill monsters and plunder their abilities! Fuse skills however I like! There’s no limit to my evolution! The useless skeleton Su Yuan has gone on a killing spree! From useless skeleton to Lord of the Undead, Su Yuan carries the aloof campus beauty to victory every step of the way! In debt? I’ll stomp a rich young master into the dirt until he begs for forgiveness! Look down on me? The five top universities can get on their knees and beg, and I still won’t go! My name is Ling Qiuxue, a heaven-blessed prodigy with a 100% affinity! The whole nation expects me to contract a divine undead and make China tremble! But I never imagined I’d end up contracting a talentless skeleton! Family burdens, crushing debts. Just when I felt like I was suffocating, I seemed to discover that my little skeleton was somehow special! He can pull out a rib and use it as a pen, and he can evolve endlessly! He can snap off a rib and use it as a throwing knife, aiming only at scumbags! A crisis in a secret realm? A ferocious Level 15 insect can instantly kill my teammate?
