So the book I can't remember the title of featured domains as a part of combat. The main character developed a domain at a young age so it astonished everyone. I keep thinking of "God Slayer" by ksy but I don't think that's it. If you post please give me the chapter it happened in or at least an estimate of which chapter. Thanks ahead of time for help.
Gonna have to be a bit more specific then that for me to answer like what was his domain about, sword, withering, ice etc
Domain, eh? My best guess is 'It's Hard to Be A Man After Travelling to The Future'. The story about Ling Lan, died because of excessive spiritual power in the last life, then transmigrated into interstellar era with a system called 'Little Four'. She enter domain stage at the first or second year of her 2nd school, maybe at 17 or 18 y.o. It's still considered as young age.
I can't remember what the domain was based on, also I think the main character was described as having red and black energy swirling around him. Edit: I have a vague idea is was like bloodlust or asura based.
