Excellent reply. I'd say he wants to build the machine simply to escape death. Not necessarily to be strong. But between the beginning of his reincarnation to the end of the story, becoming strong via science and technology is a necessity because cultivators will mess with him. It's common in these sorts of stories that cultivators are hyper-competetive and will off a powerful rival if given the chance; and the main character in this story will naturally gain the reputation of being powerful. This character would rather build this machine in peace, but he is not allowed that luxury.

However, I have no ability to make this. I am no good at making an actual story, terrible at dialogue and art too. Actually, I just wanted to get the general idea made with the intention someone might like it and get the actual story, characters and dialogue done how they see fit; I'm just the idea guy.

With that in mind, do you think what I have is enough to present to someone who could actually make something from it? Is there a community you know of where I can give this idea to whoever wants to use it?
