Elf: Evolve from Charmander to BattleGreymon

Introduction: My name is Lin Xuan. I traveled through time and became a Charmander! Fortunately, I have awakened the lying-down system, so I can upgrade by eating, sleeping, and sunbathing every day! But I didn’t expect that my evolution route was so different that I could evolve into BattleGreymon! ? ........My name is Xia Lixing, a champion-level peak trainer, known as the number one genius in history! Reborn twenty years before the extinction of mankind, I must reverse the course of history and save the fate of all mankind! Originally, I thought I had conquered a creature with unlimited potential.
