Starting from a Desert Island

I liked reading martial arts novels when I was in junior high school. I like to read Jin Yong, Liang Yusheng, Gu Long, Liu Canyang, and Chen Qingyun. Later, I don't know when, I suddenly became obsessed with online novels, immortality, fantasy, alternate history, time travel, tomb robbing, espionage, zombies, islands and other online novels. There haven't been many good novels to read recently. Just try to write a time-travel adventure island novel. During a trip, four brothers and friends accidentally traveled to a different world island, where they built homes, had various adventures, cultivated immortals, and watched how the protagonists conquered the other world continent outside the island. This is my first time writing, please take care of me! Thanks!
