This Trainer Is Super Strong but Too Mean

When he woke up, Su Ming found that he was back in his senior year of high school. But... Why is the college entrance examination a battle between elves? The swamp jumping fish who has seen through everything, the naive turtle, and the garlic bastard... Su Ming is a little confused. Wilderness, labyrinth, the ultimate world... This is a world where elves come to reality. Su Ming's goal is to become an excellent trainer. Ps: This book is also called "Your Elf is My Elf", "I Admit I Am the Appearance of Greedy Shannaido", and "The Free-Price Elf Master"
