On what i see

On my eyes the one who sends the monsters through gates are the rulers like the king of the giants said they were captured and maybe the monarchs are not enemy because i remember after the S rank dungeon raid in seoul theres monarch thats appears and if they were really enemy why would they put the mana gem collectors to sleep in stead of killing them we can say that theyre only being careful but.
I ..remember that theres the creator that tryin to revive? The shadow monarch and i also remebers that when sung jin woo are on peeking on the memories of the shadow monarch or something like flash back the monarch use hes power to revive or make a shadow soldiers through the killed monsters and in that way why the shadow monarch is so powerfull thats why maybe the shadow monarch got killed? By the rulers and the creator reviving him or something like that dunno i dont wanna read the novel i think if i read ill get bored reading the manhwa version or something like that its more thrilling if u dont know whats gonna happen next xd thats all ~
