City of Sin (Yanyu Jiangnan) - Vol 9 Chapter 85

God's Seal Cathedra Rex, Part Two!Two sons of the dragon, each different; a genius elder brother and a good-for-nothing younger brother, who despite being identical twins, are worlds apart. However, they share an identical desire for peace. On the night of their birth, the moon was high in the sky.

Rein Aster was just a herbalist farmer from a border village.A nobody. A background NPC in a story filled with prophecy and divine warfare.But by chance—or fate—he saves one of the 7 Demon Lords during a catastrophic war event. Instead of killing him, she falls for him.Obsessively. Violently. Eternally.And then… so do the others.Each Demon Lord tries to trap Rein as her personal lover/pet/priest/husband/god, building dungeons, illusion palaces, soul prisons—but Rein keeps escaping. Quietly. Cleverly. Never fully rejecting them—but never submitting, either.Why?Because Rein realizes something:The gods are worse than demons.The heroes are tyrants in shining armor.The world is collapsing—and he’s the only one they all listen to.So he hatches a plan:Use the Demon Lords’ love to take over the world.Pit them against the heroes. Unleash them on the gods. Make them fight for him. Make them kill for him. Then tame them all.Not as a king.Not as a savior.But as the lover they would burn the world for.__________The yanderes here are darker than what you might be used to.You have been warnedThe entire novel has a dark feel. Atleast read the first two minor arcs

Witnessing her fiance’s derailment with her own eyes, she married a “poor and poor” poor second generation.

The next day, jewelry, diamonds, haute couture clothing, luxury cars and mansions were received softly.

He is a domineering president who is cold-hearted and black-bellied in front of others, and he is also a three-good man who spoils his wife, loves his wife, and loves his wife.

 …

Rumor has it that his cleanliness allergy makes him never touch a woman, but she is a complete exception;

Rumor has it that he is an ascetic man who is so indifferent to strangers that he is extremely gentle in front of her;

Rumor has it that he is generous and neat and never cares about others. After his marriage, he overturns countless vinegar jars every day…

Her married life: sweet, sour, sweet, sweet, bitter, salty;

His married life: Chai, rice, oil, salt, sauce, vinegar, vinegar, vinegar, vinegar, vinegar, vinegar, vinegar, tea.

- Description from novelbuddy

“The masterminds are cooler than heroes,” I mutter as I stare at the chess pieces before me. It is easier to be the one who sits in the shadows and moves the pieces, likewise deciding the flow of the game.Heroes will foolishly sacrifice their lives for the good cause and villains will sacrifice the world for their own gain, but masterminds will use both the heroes and villains to their own benefit.Why, you ask? Well, that's because I've lost my life once while trying to be a hero so, I don't want that anymore. I'd rather be a mastermind who molds the world as per my convenience and live peacefully. Because, why not?***[Defender of Divine Glory says you are the hope of this world.]What?[Goddess of Wisdom believes that you will be the one to save the world.]Wait, what?![Propose the Grand Duke the idea of a fake marriage.]And, why would I do that?![Stop the assassination of Prince Eric.]Why would I save him?![The candidates for the throne are:... Who will you choose?]Ah! I give up...It seems like a curse that anyone who wishes for a slacker life in Isekai will have to go through the most troublesome things.In my past life, I died because of one rookie mistake but after being transmigrated in the world of fantasy I've gotten an opportunity to start afresh, but unlike the protagonists who look for their love and glory, I'd rather make money and live a life of a slacker.I have magic, I have power and I have money, what else do I need?Well, that was the plan but this damn system is getting on my nerves. I mean who in their sane mind would want to mess with the complicated royal family and political affairs? But that's not all though.I've also become the saviour of this world. Things just can't be anymore worse!Besides, the penalty of failing this quest is...[Failure: Destruction of the World.]It seems like if I screw up in selecting the right person then the destruction that is going to befall the world won't be stopped.If I speak of my reward then it's this vague thing.[Reward: Fulfillment of any wish.]“If that's the case then, I'd rather choose the person who would be the best fit for the throne.”And that's how I decided that I would become the Kingmaker.
