Looking for a manhwa!!

I saw this one manhwa on tiktok but I forgot the name, so basically it was a manhwa where the mc was a child that used to be poor and uh weak but then in the future the mc became really powerful and ruled the murim. It had reallyy nice art the mc has black hair (⌒▽⌒) (I tried going to my watchlist but it wasnt there （/TДT)/ )
