My RV Takes Me Across Worlds

In the tenth year of the New World, 70% of humanity has supernatural abilities, and 99% of those with abilities had already reached Tier Two or higher by the fifth year of the apocalypse. Yi Wudu's ability, "Book of Experiences," only needs him to gain knowledge and experience to level up. But after eight years of hard work, he had barely made it to Tier Two. Fortunately, the upgraded Book of Experiences was beyond his imagination. It was definitely not the nearly useless B-rank ability the base had detected. He had planned to take his newly advanced "Book of Experiences" and join a large, stable eco-city, where he could keep enjoying life as a layabout pampered by his doting dad, writing books when he felt like it and secretly leveling up on the side. But his RV had other ideas. The moment they left the small base, his RV took him and his doting dad along on a strange journey, shuttling back and forth between another world and the wasteland. Giants and giant forests, spirit-infused objects and a continent that never ends, a mysterious magical continent divided by the Boundary Sea, a stormy sea leading to unknown worlds, and a vanished divine realm alongside aerospace technology... And during these exciting travels, he also discovered the right way to use the "Book of Experiences." (Be sure to read the note below!) P.S. Dad: "The following is Yi Wudu's pointless whining~" Excerpt from Wasteland Observation Report: Throughout human history, people have repeatedly predicted the end of the world. Natural disasters, epidemics, resource depletion, and so on would destroy everything. But when the apocalypse really arrived in 2045, people realized that all of the above had been no more than a faint breeze before the storm that overturned the Earth and swept away human civilization. Observer: Yi Wudu. Date recorded: January 7, 2045. In 2054, the tenth year of the apocalypse, the "door" to the truth behind the apocalypse opened before me. At the time, I was immersed in the comfort and mystery of another world, and I still didn't understand what "it" truly meant. A year later, countless "windows" appeared before humanity, hoping to devour this planet struggling to hold on to hope. I looked forward to the changes "it" would bring, for better or worse. Observer: Yi Wudu. Date recorded: February 15, 2056 (Lunar New Year). P.P.S.: 1. No CP. A travel, adventure, and exploration story moving between the post-apocalyptic wasteland and a fantasy otherworld. Thank you all for your support! 2. I don't really recommend reading this. It's something of a hidden treasure for the author. When I started writing, I wanted to depict all the fantasy worlds in my head, and didn't realize the subject matter was drifting further and further off course. It ended up more like a collection of stories built around a setting. Then, because the numbers were so bad, I became increasingly anxious and rushed to finish the storylines later on. The style varies a lot from beginning to end. [Please don't read this.
