Pokémon Go Pikachu

This Pokémon fan novel tells the story of Ye Ziyu, a senior Pokémon fan, who travels to a modern parallel world full of technology, where Pokémon and people live in harmony. But I found that there is no standard welfare gold finger for time travellers. Ye Ziyu was confused. Without a golden finger, he could only rely on the Pokémon around him and the knowledge in his mind~ There are no bug-type Pokémon in this article, there is no female protagonist, and there are various systems and technologies that I personally think are relatively complete and scientific. This is my first time writing, please give me some advice~ This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
