How to Train Your Dragon: Travel Through Time Begins with the Adventures of Jackie Chan

(It is a continuation of my first book Hiccup's Bizarre Adventure. New readers of this book can read the first book I wrote before. After reading this book, you will feel more comfortable reading it.) The boy riding the dragon passed through the pink and purple whirlpool and came to a world that opened his eyes. The first thing he did when he came to this world was that Toothless had a red thing attached to his body. To understand it, he had to start by understanding the cities near the Thames River.
