Reincarnated in How to Train Your Dragon and Hiccup is My Brother"

Note to the reader: The original synopsis has been adapted to introduce a fusion of worlds with different visions, making the story’s crossover elements more natural and meaningful. After dying in his original world, Rock is reincarnated as Hiccup’s older brother in How to Train Your Dragon. He thought his life would be peaceful — but everything changes when he meets a character from another story who reveals the truth. The Earth has mysteriously expanded a hundred times, now divided by magical barriers called the Walls of Legend, which separate different realities. Rock soon discovers that many worlds — like Hotel Transylvania, Encanto, and many others — have merged together. At the center of this chaos is a divine artifact, broken into fragments and scattered across the world. Whoever gathers all the pieces can rewrite reality and become the new God of this universe. Now, Rock must protect his family and explore these dangerous worlds. ---
