[Marvel/DC/Honkai: Star Rail] What a Good Path, It Drives You Mad

The protagonist is a native of Earth, with a Honkai: Star Rail game linked in his mind. He grew up doing blacksmithing. The protagonist gets into Gotham University and encounters an excellent PhD student who blows up the school, corners him in a bathroom, and is sharpening a knife, ready to kill him. Protagonist: The Joker bomb was only 0.01 meters away from me, but I knew the situation would be perfectly resolved in five seconds... System: Stop standing there waiting to die! Aaaaaah, Honkai: Star Rail, activate! Then the protagonist plays through every Path in Honkai: Star Rail, one after another. He starts doing missions, pulling Light Cones, disguising himself as Honkai: Star Rail characters, using secret identities to make the superheroes notice him, falling in love with Aeons, and doing the sorts of things Trailblazers do. The protagonist's mission 1: Pretend to search for Honkai: Star Rail characters who have entered Earth, and complete the missions issued by the System. The protagonist's mission 2: Pursue the Aeons' attention and spread the Paths of Honkai: Star Rail. The protagonist's mission 3: Become Gotham's trash-can king with style. What the protagonist actually does includes, but is not limited to: Take the Path of Abundance to find the Hunt, Take the Path of Destruction to find Nihility, Take the Path of Order to find Harmony, Take the Path of Propagation to find Preservation... In short, he's asking for trouble. Luckily, the protagonist eventually discovers that these Aeons are all Aha messing with him. Protagonist: ...Stop bothering me, I'm thinking! Note: Aha is the love interest. Aha is responsible for disguising himself as the other Aeons, while the protagonist disguises himself as followers of different Paths. It's all about producing and consuming in-house. The Honkai: Star Rail characters' secret identities won't have romantic pairings. When they show up, they're the protagonist's relatives. The protagonist will do his best to explain where all these uncles and aunts came from... Finally, the train database administrator x the worst batch of Nameless in history. There's plenty of steamy stuff. I haven't figured out the plot outline yet. A story about romance with nonhumans: At first, the protagonist met an Aeon. They fell for each other at first sight. Later, the protagonist met many more Aeons. In the end, they all became his wings (that's how it is). Theme: Joy is the privilege of intelligent life.
