- Description from Novelupdates

This is the story of a boy who lived a secluded life in the mountains, tending his farm, rearing his fish, and dreaming his dreams. Eh? Did I suddenly conquer all worlds and become the big boss? Or am I still in a dream?

An Individual from Earth finds themselves in the Shinobi World, equipped with a Scientific System. From that moment, he delved into scientific research far ahead of its time.

Kai Tensen’s life ends in a freak accident, only for him to wake up as a newborn in a completely different world filled with magic, danger, and a “System” providing him with information and secrets of the world. But his second chance at life takes a deadly turn when he discovers the truth: he’s the first necromancer in over 500 years, and the world will do anything to see him destroyed.Hunted by the fanatical Inquisition, Kai must outwit bounty hunters, corrupt mages, and even gods themselves to survive.As Kai’s strength grows, so does the danger. Each step into his newfound powers tests his humanity, forcing him to confront questions of loyalty, betrayal, and the cost of his ambition.But with whispers of a divine conspiracy and ancient relics that could shatter the gods’ control, Kai realizes his fight isn’t just for survival. It’s for revolution.In a world that brands him a monster, Kai vows to outlive his supressors. If they want a villain, he’ll give them one. The gods called him a curse and the church called him evil, but he’ll prove he’s their reckoning.Death is only the beginning.Author's Note:As you may know, I'm also the author of Fractured Horizon, a slightly futuristic fantasy/sci-fi novel about mutated human monsters and psychics that battle them. I also wrote My Undeath, a reincarnation novel set in a fantasy world. It wasn't my best work, but I loved writing the story.I put a lot more time and effort into Reborn with a Necromancer System, and ironed out the details for a while, plotting approximately 500 chapters for all of you. If you liked either of my other two novels, this novel has a lot more planned for it than the other two.
