Yes, I recommend a novel called "My Orchard in the Other World". It tells the story of the protagonist transmigrating to a planet similar to the Avatar world to plant fruit trees, explore, and hunt for treasures. He can constantly travel between Earth and the other world. It suits your needs very well. In addition, there was another book called Wandering! The novel, Blue Planet Man, tells the story of the protagonist becoming the consciousness of the planet on the wandering earth, taking away the characters in Avatar while traveling through time and space, and destroying the invader's home planet. It is also very suitable for your preferences. I hope you like my recommendation. Muah ~
