He could have, at least, saved the blood from necromancer in a jar to drink later to see if he'd get any skills from him if he couldn't turn him into a servant.

I hope he gets another servant space and turns the necromancer into a vampire.

Too bad Lyle can't turn the necromancer into his servant, unless he gets another slot after killing so many undead.

Will the new assassin have a name too or you'll kill him soon?

I know he has Ruby, Lostred, Drakor and, now, the new assassin. Who is the 5th servant? I think you're getting confused. Isn't the tall guy, Lintosh, the 5th one!?

There's clearly a part missing when Jake is explaining about the new world.

Doesn't he have a second class called "Ruler of Darkness"?

Don't he have the a second class called Ruler of Darkness?

He wasn't a golden knight before the system

Can't he bite them, give his blood and make them his servants? I bet they would evolve into true vampires.

Why not simply put the body in a spacial ring?

Alexander needs allies in order to survive. He can't do everything on his own. Prince Noah could also make the red-headed boy his personal page and future knight since he's also seen Alexander true appearance and ask him to protect his brother.

I believe he should reveal his secret to Prince Noah and Nicholas at the same time. Also he should show Lady Elizabeth letter to them. Prince Noah would certainly want to protect his little brother and Nicholas could bring news from outside the palace to them. Alexander could help Noah improve his control over his magic and, if Prince Noah sees his twin sister as trustworthy, he could help with revealing the secret to her as well. Princess Isabel could teach Alexander everything she learned about light magic while he would teach what he developed by himself. That way he would solve his problem about learning light magic. I believe invisibility magic as well as the way changes his appearance and create illusions are new abilities he created because of his knowledge of science from his previous modern world. He could just tell her he created them out of necessity since needs hide who he is.

And the magic books!? Didn't he get many of them? Can't he learn or simply absorb their magic spells?

That doesn't make any sense. How will he get to the demigod level!? As far as I know there are no other demigods besides that guy who serves the G.O.D.. There's also the fact that regular people doesn't rank up by killing and eating each other's cores. There wouldn't be a civilization in the first place if they had to kill other people just to advance.

He even bought a water-darkness spell called [Dark Tide] but he never casts it.

I simply cannot understand why the author doesn't make use sword skill he learned from Excalibur/Caliburn which only works with his light element.

That's one thing I don't understand. Emery has powerful water spell called [Dark Tide] which could be used to counter fire ones, but the author never ever makes him use water-based spells against fire mages although water is one of Emery's elements.

I don't know why Emery doesn't use the sword skill he learned from Excalibur/Caliburn which is only compatible with the light element.

what is the purpose of the stage 3 fey warden anyway!? You never mention or use it as if it's completely useless.
