I actually have two plans for this project, and I'm torn between them, so I'll ask for your opinion.
1. Rewrite the work from scratch — it won't take me long, about a week for every 15 chapters. I'll also make sure to adjust the characters so they better match their personalities in Marvel (it seems that only Tony's personality is accurate here, as he's arrogant like in the Chinese novels).
In addition, I'll include some characters from the DC universe. The story won't just revolve around the Marvel List; instead, it will expand, and the list will become more of a secondary element.
2. The second option is to continue the existing chapters (75) and finish the story my own way. I'll also make sure to include DC characters and develop Isaac's personality—since he's arrogant, he could use a bit of a beating. I'm also considering bringing in The Boys universe, making it a wide story with plenty of events. This option suits me well since I've already prepared 10 chapters in advance.
I'll leave the voting to you. I'll put the numbers 1 and 2 in the comments, and whichever gets the most votes within 48 hours will be the one I go with.
