The Trainer Should Start the Involution from the Elf Egg

When others travel through the world of Pokémon, the mythical beasts will follow them, and the system will follow them. Only when Li Feng really traveled through time did he realize that there was no golden finger, only an attribute panel that could see the Elf state. When others relied on the bond of blood to explode, he was studying the ratio of energy cubes and targeted training; when others clicked one button to reach the level, he was studying elf pathology and an introduction to combat. This adventure seems a little different? (Pokémon and Pokémon fanfic, with a low gold finger content and a realistic worldview)
