“Who would have thought that one ordinary review could instantly fuck your life? Definitely not me”******Luke was your average teenage boy—with an unhealthy obsession for light novels.After finishing a new read titled “The Hero’s Obsessed Harem,” he jumped online to post a review. His biggest issue? The so-called “hero” kept stealing other men’s love interests, and somehow, the story praised him for it.Right after posting the review, he got an odd reply from the author:“You think my book is flawed? I’ll make you regret that.”Luke brushed it off as a salty writer who couldn’t handle criticism—until everything went dark.The next time he opened his eyes, he was in the body of Riven Von Grave, the fourth son of the low-ranking Grave baron family—an irrelevant extra in The Hero’s Obsessed Harem. Riven was a forgotten character, engaged to three duke’s daughters since childhood, only for all three to abandon him for the so-called hero. And to make matters worse, he was fated to die in a war against demons—utterly forgotten.But Luke isn’t having any of it.Screw fate.Screw the plot.And most of all, screw the author who threw him into this mess.Armed with a mysterious system and pure spite, Riven is going to rewrite his destiny, and win back his fiancées as well.But with every change Riven makes, he changes the story, and pulls a calamity bigger than the demons toward them. What will he do when he realizes the impending doom, will he be able to fix his own mistakes?

Upon waking up, the whole people crossed the alien world.

This is a terrifying world, almost immeasurable.

There are dragons, griffins, goblins, goblins, dwarves, and orcs.

There are also zombies, undead dens, and various mythological monsters.

Everyone is a lord, starting with a life experience, a small courtyard, and three farmers.

To get rich, start by arranging trees and gradually establishing territory.

Lords need to explore the map, occupy areas, obtain resources, develop urban construction, and conquer monster dens.

Every other month, you need to resist the looting of monster legions and various alien forces in order to survive.

Zong Shen started the game and awakened the strategy system.

Raiders will appear in everything you can see.

Help him find all the hidden treasures.

[The crooked neck tree 50 meters southeast of the territory is actually not simple. 】

[Go forward 35 steps from your current position and start digging, you will get a surprise. 】

[Don’t look, this treasure chest is a trap, and the poison gas inside will make you unconscious for three days and three nights. 】

While others were still struggling to support, Zong Shen had already built a strong city.

With countless powerful soldiers and epic heroes, resources are piled up like a mountain.

Epic dragon Nithogg: “You…Don’t come here…I will give you all the treasures!”

Chief Goblin: “I am willing to serve the adults.”

King of Avalon: “I am willing to marry my beloved little daughter to you…”

Zong Shen: “Children make choices, I want them all!”
