Since it's a modern word.. I'm expecting assault rifle, tank, rocket launcher, attack helicopter, jet fighter and so on vs super powered flying cultivator that can use magic/runes with only his mind and hand gestures..
Awesome concept, I love novels where people from cultivation come to “earth” despite the fact this is just the future of the cultivation world it’s very cool, if you want some inspiration I suggest strongest son it might help you think of some deprecation to go with this novel. I think there should be some old monsters hidden around otherwise it would be too easy for the mc, and I think he should perhaps start a roaming sect where it’s not locked in to a single location and all the members have ways to contact each other for example phones (obviously) but maybe get the mc to recruits someone who is amazing with tech so he can incorporate him into the sect and he and the tech guy can create some incredible weapons
