What are some popular tropes in sci fi crossover fanfiction?

I was a genius in the Earthen Plane. I was a cripple in the Spiritual Plane. I was dead in the Cloud Plane. After experiencing death in the form of dragon sneeze, I find myself back in my room in Earthen Plane where I was a genius. I had been too focused on training myself in the past life. Now that I've been given a second chance, I should just enjoy my life to the fullest extent! Instead of locking myself up in my room to cultivate, take in a few disciples so they can help take care of me! Easy life is best life! The other Planes suck anyway, I'll just lay back here and relax! All I need to do is to teach my dear disciples on the things I've learnt while they take care of me! Huh? What do you mean one of my disciples destroyed the Sinister Demon Sect last night? Do you not see how she's here massaging my shoulders now? There's no way my disciple could have obliterated the all-powerful Xi Family, can't you see she's obediently pouring tea for me over there? You must be delusional to even suggest my disciple could have flattened the impassable Death Mountains, just look at how cute she is taking a nap under the cherry blossom tree. What do you mean my cute disciples are Yanderes? *** Notes: Side Stories in "My Cute (Yandere) Disciples' Side Stories" If you're here for the R18 tag expecting adult scenes, know that this was a decision I made quite late into writing this so the scenes only come up very late into the story. One or more of the disciples may or may not have a tragic (depending on personal opinions) backstory that may or may not offend/disturb some readers (depending on your personal opinions/mental fortitude/openmindedness/morality/sexual orientation/real world knowledge/political agendas/reaction if someone gave you lemons/view on whether the Earth is flat or round, which I personally think it's neither and is actually a donut nom nom nom) which may or may not affect the rest of the story significantly. Consider yourself sufficiently warned. Story inspired from "My female disciples are scary" by feeling_tired Cover is done by the really awesome Lumi!

But after a while, it will pick up quickly. . . Now, back to the synopsis. Er-Erhmm.. (narrator-voice on) ... In another world called Blue Star, the famous son of wealth, Dorian D. Tian, is thrown into a whirl of unfortunate circumstances, resulting in his death. . His parents had a brutal car accident that left them in a coma, and his uncle had quickly taken over the company,  and seized the company, making sure that he was financially crippled for good. With that, the famous young master struggled desperately. And in the end, he gave in to his despair and depression, leaving the sad, lonely world. The end? Heh... Think again! Because in that brief moment, the lifeless corpse suddenly opened its eyes, revealing a deep calm look. That's right. Another mysterious soul had entered the body. But if one thought this story was just about revenge, then sorry... that wasn't even the half of it! .... The mysterious entity suddenly triggered an exorcist system. And from then on, both humans and even those from the underworld shuddered in fear and despair at the mysterious soul's cruelty. [Humans]: "Demon! Demon! You're definitely a demon!" [Demons]: "Help! Help! The famous demon wants to eat me!" [Evil Spirits]: "You!... Are you the one who is an evil spirit or us? Why the hell did it seem like you're the demonic one instead?" [Ghouls]: "You stay away from me! Stay away from me now, you evil entity!" [Hellhounds]: "Are you sure you're not the son of hades?" The system couldn't help looking at its host in doubt. Its indicators said that its host was indeed mortal. But why did it feel like something was wrong with its host? Dorian lightly chuckled in amusement. He would also like to ask the same question. What exactly was his identity? Well, this would be the biggest mystery of all. But Dorian wasn't in a hurry. Who were his enemies, and who were his allies? Soon, he would find the truth. In the meantime, why not play a little? "Demon! stay back!" "Oooo~~~... I... I want to go back to the underworld where it's safe." "Run for your lives! The demon is here!" …..
