I found it out just now, the story is called Devil Sword King. ------------------------------------------------------------------------------------------------------------------------------ So recently, this manhua/manhwa came up in my mind from a year or two ago similar to murim online and world apocalypse online where It had these elements: The Mc can transfer between Murim and Earth The Mc ends up becoming the leader of a sect? The Mc falls in love with a girl but she dies and becomes depressed, secluding himself on earth He has a black and white sword with spirits inside of them Some characters on earth are an exact replica of murim world such as the MC's wife (who is alive on Earth but doesn't know him since she is technically a different person) The story is meh but its been stuck in my head for a good while Oh yea, I think the way he goes in between worlds is through a mirror?(I could be completely wrong) It should have 100+ chapters Anyways, sorry for not further elaborating further, If I remembered anything else then I would have said it on here. If anyone can find it, that would be great and a good deal of help to me.
