The Legendary Rebuilding of a World by a Realist Demon King


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

In a rotted away castle, Ashta awoke as a Demon King.
With his ‘wisdom from a past life,’ he would rule over his lands as a thorough ‘realist.’

“Demon King, why are you attacking the level 1 Heroes?”
“Defeat them before they become stronger. That is called strategy.”

“Demon King, why are you sending fake money to the enemy country?”
“To bring chaos to their economy so they will self-destruct.”

“The werewolf troops have attacked. Should we use silver bullets?”
“Not bullets, shoot them with canons.”

And like that, Ashta ‘reformed’ the old tendencies.
He became a lord who was loved by the people and his subordinates and would go on to be called the most powerful Demon King in history.

The backstory for the MC is that he has no solid knowledge of the past, and came from a world that isn't Earth. Then suddenly the MC remembered he used to research Japan so now here is a bunch of knowledge obtained from Japanese games and earth's history. The author wanted to fool us that this would not be the generic isekai. Instead of pretending the MC was born and raised in not-Japan, just say he was a former Japanese person as it'd be more believable, given the amount of... more>> knowledge he knows about Japan.

This story is shaping up to be your generic copy paste. Japanese MC who is meek against women. Maid. Gachas. OP levels of luck. We'll see what happens as the translation continues but it seems like a knock off of "How a Realist Hero Rebuilt the Kingdom", except the author is trying to have this MC be everything the opposite of Realist Hero's MC (demon, being deceptive and cruel, physically strong, win without uniting nations, annihilating the enemy, etc.). I say knock off because this WN came out in 2018 and Realist Hero came out in 2014. <<less

Casual Machiavellian know it all, with a smart loyal maid..... there may be some wish fulfillment self projection on the part of the author.

Chapters are extremely short so it’s a slow take off, but TL is pretty smooth. As other review has said, maybe let some backlog build up to you can keep a flow going.

I wouldn't usually give a rating, especially not such a low one, so early in but at this point I think I've seen enough.

The guy keeps coming up with "innovative strategies" that any rpg noob with half a brain can come up with and recieves cringingly overwhelming praise for it every time. You mean to tell me that of all the 71 other demon kings that have been existing before this guy that not one of them have thought of killing off any of the 72 heroes before they grow... more>> up and gain power? And why in God's name would every Demon king be tasked with keeping in their castle a weapon that the hero specifically can use to gain a huge advantage against them? Probably so the MC can come up with the BRILLIANT idea of getting rid of it beforehand, you know, cuz unlike all the other "stupid" demon kings he's a realist and he has no problem reminding us of that at least twice every chapter.

Maybe it wouldn't have been so bad if the dunge-*ahem*, Demon king castle system at least was somewhat interesting, however to summon monsters all he does is literally throw ingredients into an actual pot and something pops out, also apparently using the same ingredients doesn't give the same monster. This is literally a gacha that's been unsuccessfully reskinned.

Pretty sure it won't be long before this novel flops into a burning pile of MC being glorified by all his companions for coming up with subpar and overused ideas. <<less

In truth I began reading this only because I saw the "Adapted to Manga" tag, as I held intital expectations that would mean the story would not be utter sh*t, but then again upon further contemplation I realized I have seen some completely sh*t mangas. So I don't even know why I read this, and furthermore I can't find any english translations to ascertain the quality of the manga.

Anyway onwards to reading the novel. My biggest impression of what I saw is that it was very short. With each chapter... more>> being about 1-2 pages of text, I 100% recommend to let the chapters stack up to at least 20 before beginning reading. <<less

As only 3 chapters have been released it is not possible to do anything but give the shallowest of reviews; so I wont even try. I love kingdom building and hopefully this can add to the small pool of kindom building novels. I do think though that the translators should have done an initial mass release to garner attention and traction.
