Myriad Worlds Dungeon: From the Start, Patrick Star's Revenge

Lin Yesheng is transported to a parallel world by a toilet. This world is filled with countless dungeons! The good news is that they’re all based on works he knows, and none of those works exist in this world! The bad news is that the authorities have already thoroughly explored most of the dungeons. Even though the source works don’t exist here, there are detailed guides! But when Lin Yesheng enters a dungeon, he discovers that his version seems different from everyone else’s! “No way... Patrick Star is going to destroy Bikini Bottom!” “No way... Journey to the West is a scam perpetrated by the Primordial World!” “No way... this entire world is one giant dungeon!” Watching the dungeons mutate as soon as he enters them, Lin Yesheng can only look on helplessly. All that’s left is to sit atop the river of time and look down upon the world. (These worlds are all completely different from the originals. They just borrow the original characters and framework. Come give it a try if you’re interested, as long as you can put up with my terrible writing.)
