Elf: I Can Upgrade Infinitely

Lu Yuan traveled to a world where elves and humans coexisted, but the elves in this world seemed to have a slightly different fighting style. One hundred and twenty years ago, the Elf Alliance invented the Poke Ball, and the profession of trainer was born. However, humans are not willing to gain power through the indirect method of training elves. Instead, they want to directly control various magical abilities like elves. After countless attempts and failures, the energy transmitter was born. The elves transfer the energy in their bodies to humans, and trainers have become the most noble profession. Lu Yuan came with a system that could be infinitely upgraded and ascended to the pinnacle throne of the strongest trainer. This novel and its characters are purely fictitious.
