In such a world, there was such a young man. He made his way upstream, stepping on blood, defying the emperor, destroying the various kings, and slaughtering his way through the hundred clans to form an Immortal Path towards the throne of Sovereign!

Emperor Zi Yu used 5 strikes of his axe to split mountains and unify everyone underneath the heavens. He partitioned the land into 9 areas, thus establishing the Nine Cauldrons which eventually became known as the 9 prefectures.

When I opened my eyes, I found myself trapped in the very novel I despise most, and to make matters worse, I became Samuel Gebb, the tragic main character. Samuel's wife constantly brings other men into their home, and he’s forced to endure her mowns with other mens.But here's the twist: I’m not Samuel. I’m the Heavenly Demon, a being feared by the world for my martial prowess.In my first life, I was just an ordinary student who read this novel and became deeply depressed for months. In my second life, I took on the role of the Heavenly Demon and conquered the world. Now, if Abigail, the female lead, thinks she can control me like she did with Samuel, she’s gravely mistaken. I’m going to ensure she pays for what she did to Samuel.In the novel, Abigail claims she never slept with any men, but I don’t believe her, even if she’s telling the truth. I’ll make her regret the three years she tormented Samuel.Original Novel: The Marriage she turned into War.Author POV: this was utterly disgusting Novel and I'm seriously thinking why Webfic wrote it and what is the reason for Author to make Main character Suffer So much, So this will be more like a Fantasy Friction of Original and I'm gonna make sure this Novel will be MasterpiecePlease don't get me wrong but after Reading the Original Novel I'm having Trust Issues with Love and Marriage but will see if I want to make Main character to Ship with someone or to Give him Harem.
