Hi guys, do you know what webtoon it was, like similar to orv, or solo leveling.
I remember how the ml has a big white room in the basement or smth, and he sometimes get's his ghost(?) non human allies out (inkl. Angels, and maybe a lich?).
I think he had two swords that could talk. Maybe he was weak in the beginning? Not sure but if someone has a hunch please let me know!!
