it was something like demonic cult sect leader x heavenly leader
i think it was a manhua or manhwa (murim or wuxia) and the demonic cult lead was idk a demon or dragon. they both also had their respective white/black hair and the demon cult leader was possessive

This one maybe?
i remember it was about this guy who was tryna find his dead brother or smth and had his phone
the phone had like an app on it where people had usernames and could chat but it also had skills on the app and one was to see text messages of other people (inside and outside app)
yeah idk it was a while ago and it wasnt a bl/yaoi
I'm pretty sure it's this one
