“After every fire, ants survive.”

…

Mysterious anomalous biological metals have polluted the world, and the world has undergone tremendous changes. Metal sickness is like a key that opens the door to evolution. Under the tide of evolution, there are no innocents.

The choice is up to you, do you want to be the surviving ants after the fire, or do you want to risk your life, step on the glorious long steps to the gods, and glimpse the supreme glory of the mother goddess?

…

Touch the totem in your heart, follow the inspiration, and step on the long steps of ascending to God:

[Amphibians] → [Atlantic Glory] → [Ningen]…

[Eight Arms] → [Nightmare in the Sea] → [Deep Divers]…

[Eagle Eye] → [Owl Ghost of the Night] → [Jersey Demon]…

[Living Dead] → [Grave Digger] → [Death Ferryman]…

…

“On that day, the world was polluted, and I was the source of pollution. Human desires are endless, desire is the best food on the way to evolution, and I am the embodiment of desire.”

– Joe Tour.

- Description from novelbuddy

She was a medical expert, talented and beautiful. She was reborn as his little wife. Her in-laws did not like her, her husband did not love her, and she was as timid as a mouse. She was weak and easy to bully.

“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?

Zavier met Cosmic Consciousness after his death. He was satisfied with every system that Cosmic Consciousness exhibited, so he wanted all of them. Surprisingly, the Cosmic Consciousness obliged him.

Zavier was reborn in an isekai full of magic and alchemy. Now, he had many routes to upgrade. Interestingly, to coordinate these systems, Cosmic Consciousness gave him the gift of being able to duplicate himself. He could clone a finite number of himself to manipulate these systems.

Magus, Alchemist, Mesmer, Tamer, Hunter, Vampire, Werewolf, Dragonknight, Necromancer.....
