Jiang Hao was reborn as a senior in high school where elves and humans coexisted. He thought he could rely on the experience of being a Pokémon boss in his previous life to easily figure out the path of a trainer. However, he just watched a Pokémon battle and was immediately confused - "Wait? Charizard gathers energy? Earthquake knocks off the flying type? Why is this Pokémon battle so exciting?!" The Pokémon's Pokémon template is mixed with the battle mechanism of Rock Kingdom, and it is ridiculously stitched and over the top. As a scumbag who was always at the bottom of the school, he was caught fishing for elves and was imprisoned by his mother. He finally picked up a "waste elf" that no one wanted in an abandoned warehouse, only to find that this thing seemed ordinary, but in fact it was ridiculously sinister. While others rolled elf eggs and fought in orthodox battles, Jiang Hao did not take the ordinary path: relying on the underworld routine to make his opponents cry, and relying on the stitching mechanism to play tricks. From the scumbag who was ridiculed by the whole class, he counterattacked and became the most outrageous trainer. "Don't laugh at me as a useless elf, and don't be too dissatisfied with fighting monsters. A winning routine is a good routine!" Reborn in the elf world, Jiang Hao has only one goal: to understand the battle rules of Luo Li Luo Qi, and lead my underworld elf to dominate the trainer world!
