What did the other world do? Was there a novel like the Supreme Dragon Emperor where the male protagonist transmigrated to another world but did not know the details?

The novel,"The Mysterious Wilderness", is somewhat similar to the novel you described. The main character, Quan Xing, transmigrated to the Ancient Barrens Continent and began his adventure in the other world. With the memories of his previous life, he displayed amazing spiritual will and the Great Desolate Spell Body. He continued to grow and experience the storms of the other world. I think this book will suit your taste. I hope you like this fairy's recommendation. Muah ~😗😋
