Awakening in the body of Kael Valtieri, heir to a destitute border territory in the magical kingdom of Ardania, Ivan finds a second chance in an unfamiliar world driven by arcane forces.In this realm, magic reigns supreme, yet it is woefully inefficient and bound by antiquated traditions. Armed with the knowledge of advanced robotics and engineering from his past life, Kael sets out to merge science with sorcery, aiming to revolutionize the very fabric of magic. His quest? To uplift his impoverished territory and safeguard it against the lurking dangers beyond the border.But Kael’s journey takes a thrilling turn when he stumbles upon the remnants of an ancient, forgotten civilization.

Driven by curiosity and ambition, Kael deciphers their secrets, melding ancient ingenuity with his modern intellect to forge unprecedented defenses.As Kael uncovers the dark history of this world, he learns of rifts that once unleashed monstrous beings from other dimensions, nearly annihilating humanity. Though a powerful artifact sealed these rifts, its strength is waning, and an impending cataclysm looms.Now, with time running out and the continent teetering on the brink of another monstrous invasion, Kael must wield his hybrid mastery of science and magic to confront the rising tide of darkness. Can one man, armed with the knowledge of two worlds, avert a catastrophe and carve out a new destiny?Prepare for an epic tale of innovation, mystery, and survival in a world where the past and future collide.

It seems that my previous synopsis was not very clear, so here is the clarification:An ordinary man dies and has the opportunity to be reincarnated, but after making a mistake in front of the goddess or basically desecrating her in his thoughts, he is punished by being reborn as a woman.But later, he discovers a method to temporarily recover his male body (legacy of lust).However, his endless desire will be the least of his problems.This world is nothing like the fantasy he dreamed.“As for genres, there's a little bit of everything: Harem, Romance, Comedy, Yandere, Yuri, MILFs, Lolis, Elves, woman-beast, Demons, Dragons, Gigantes, Priestesses, Androids, incest, Group Action, Futa, a little bit of SM, and much more. If it captures your interest, great!!!”.Here is the original synopsis>>>>>“Wait, you turned me into a woman just because I imagined that? I didn’t know you could read minds—that’s not fair!”(He had defiled her in his imagination in five different ways, each worse than the last.)After his death, a goddess granted him reincarnation in another world. But his uncontrollable lust angered her, and as punishment, she turned him into a woman.“Stop!... Don’t make that choice,” warned an old voice.Through an encounter beyond reason, he learns the truth: this world is nothing like the fantasy he imagined. It is brutal, merciless, and those who let their guard down don’t live long. He also discovers a method to temporarily regain his male form.Now, drawn into a battle for power where even the gods take sides, he fights not only for revenge, survival, and ambition, but also to protect those he holds dear—and everything he has built. In this second life, forged by sacrifices beyond his comprehension, he will carve his own path… no matter the cost.
